+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ChangeLog for wpa_supplicant
+
+2008-02-19 - v0.5.10
+ * added support for Makefile builds to include debug-log-to-a-file
+ functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
+ * added network configuration parameter 'frequency' for setting
+ initial channel for IBSS (adhoc) networks
+ * fixed EAP-SIM and EAP-AKA message parser to validate attribute
+ lengths properly to avoid potential crash caused by invalid messages
+ * added driver_wext workaround for race condition between scanning and
+ association with drivers that take very long time to scan all
+ channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
+ using a longer hardcoded timeout for the scan if the driver supports
+ notifications for scan completion (SIOCGIWSCAN event); this helps,
+ e.g., in cases where wpa_supplicant and madwifi driver ended up in
+ loop where the driver did not even try to associate
+ * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
+ attributes in EAP-SIM Start/Response when using fast reauthentication
+ * fixed problems in getting NDIS events from WMI on Windows 2000
+
+2007-12-02 - v0.5.9
+ * fixed an integer overflow issue in the ASN.1 parser used by the
+ (experimental) internal TLS implementation to avoid a potential
+ buffer read overflow
+ * fixed a race condition with -W option (wait for a control interface
+ monitor before starting) that could have caused the first messages to
+ be lost
+ * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+ draft (draft-ietf-emu-eap-gpsk-07.txt)
+ * added ctrl_iface RECONNECT (wpa_cli reconnect) command
+ (like reassociate, but only takes effect if already associated)
+ * fixed a possible race condition between wpa_cli reassociate and
+ wpa_cli disconnect
+ * return a non-zero exit code from non-interactive wpa_cli if the
+ command is not recognized or fails
+ * fixed 0.5.8 regressions in BSS selection that prevented wildcard SSID
+ from being used with non-WPA networks and disabled workaround for
+ ignoring bogus WPA/RSN IE in non-WPA configuration
+ * fixed OpenSSL TLS wrapper to clear trusted CA list to allow
+ network blocks to use different trusted CA configurations
+ * fixed a potential EAP state machine loop when mloving from PSK to EAP
+ configuration without restarting wpa_supplicant
+
+2007-05-28 - v0.5.8
+ * updated driver_wext.c to build with the current wireless-dev.git tree
+ and net/d80211 changes
+ * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+ draft (draft-ietf-emu-eap-gpsk-03.txt)
+ * fixed 'make install'
+ * fixed EAP-TTLS implementation not to crash on use of freed memory
+ if TLS library initialization fails
+ * fixed EAP-AKA Notification processing to allow Notification to be
+ processed after AKA Challenge response has been sent
+
+2006-12-31 - v0.5.7
+ * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
+ * updated EAP-PSK to use the IANA-allocated EAP type 47
+ * fixed EAP-PAX key derivation
+ * fixed EAP-PSK bit ordering of the Flags field
+ * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
+ tunnelled identity request (previously, the identifier from the outer
+ method was used, not the tunnelled identifier which could be
+ different)
+ * fixed EAP-TTLS AVP parser processing for too short AVP lengths
+ * added support for EAP-FAST authentication with inner methods that
+ generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
+ for PAC provisioning)
+ * fixed dbus ctrl_iface to validate message interface before
+ dispatching to avoid a possible segfault [Bug 190]
+ * fixed PeerKey key derivation to use the correct PRF label
+ * updated Windows binary build to link against OpenSSL 0.9.8d and
+ added support for EAP-FAST
+
+2006-11-24 - v0.5.6
+ * added experimental, integrated TLSv1 client implementation with the
+ needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
+ setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
+ .config); this can be useful, e.g., if the target system does not
+ have a suitable TLS library and a minimal code size is required
+ (total size of this internal TLS/crypto code is bit under 50 kB on
+ x86 and the crypto code is shared by rest of the supplicant so some
+ of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
+ * removed STAKey handshake since PeerKey handshake has replaced it in
+ IEEE 802.11ma and there are no known deployments of STAKey
+ * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+ draft (draft-ietf-emu-eap-gpsk-01.txt)
+ * added preliminary implementation of IEEE 802.11w/D1.0 (management
+ frame protection)
+ (Note: this requires driver support to work properly.)
+ (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
+ * fixed Windows named pipes ctrl_iface to not stop listening for
+ commands if client program opens a named pipe and closes it
+ immediately without sending a command
+ * fixed USIM PIN status determination for the case that PIN is not
+ needed (this allows EAP-AKA to be used with USIM cards that do not
+ use PIN)
+ * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
+ be used with cards that do not support file selection based on
+ partial AID
+ * added support for matching the subjectAltName of the authentication
+ server certificate against multiple name components (e.g.,
+ altsubject_match="DNS:server.example.com;DNS:server2.example.com")
+ * fixed EAP-SIM/AKA key derivation for re-authentication case (only
+ affects IEEE 802.1X with dynamic WEP keys)
+ * changed ctrl_iface network configuration 'get' operations to not
+ return password/key material; if these fields are requested, "*"
+ will be returned if the password/key is set, but the value of the
+ parameter is not exposed
+
+2006-08-27 - v0.5.5
+ * added support for building Windows version with UNICODE defined
+ (wide-char functions)
+ * driver_ndis: fixed static WEP configuration to avoid race condition
+ issues with some NDIS drivers between association and setting WEP
+ keys
+ * driver_ndis: added validation for IELength value in scan results to
+ avoid crashes when using buggy NDIS drivers [Bug 165]
+ * fixed Release|Win32 target in the Visual Studio project files
+ (previously, only Debug|Win32 target was set properly)
+ * changed control interface API call wpa_ctrl_pending() to allow it to
+ return -1 on error (e.g., connection lost); control interface clients
+ will need to make sure that they verify that the value is indeed >0
+ when determining whether there are pending messages
+ * added an alternative control interface backend for Windows targets:
+ Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
+ control interface mechanism for Windows builds (previously, UDP to
+ localhost was used)
+ * changed ctrl_interface configuration for UNIX domain sockets:
+ - deprecated ctrl_interface_group variable (it may be removed in
+ future versions)
+ - allow both directory and group be configured with ctrl_interface
+ in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
+ - ctrl_interface=/var/run/wpa_supplicant is still supported for the
+ case when group is not changed
+ * added support for controlling more than one interface per process in
+ Windows version
+ * added a workaround for a case where the AP is using unknown address
+ (e.g., MAC address of the wired interface) as the source address for
+ EAPOL-Key frames; previously, that source address was used as the
+ destination for EAPOL-Key frames and in key derivation; now, BSSID is
+ used even if the source address does not match with it
+ (this resolves an interoperability issue with Thomson SpeedTouch 580)
+ * added a workaround for UDP-based control interface (which was used in
+ Windows builds before this release) to prevent packets with forged
+ addresses from being accepted as local control requests
+ * removed ndis_events.cpp and possibility of using external
+ ndis_events.exe; C version (ndis_events.c) is fully functional and
+ there is no desire to maintain two separate versions of this
+ implementation
+ * ndis_events: Changed NDIS event notification design to use WMI to
+ learn the adapter description through Win32_PnPEntity class; this
+ should fix some cases where the adapter name was not recognized
+ correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
+ USB) [Bug 113]
+ * fixed selection of the first network in ap_scan=2 mode; previously,
+ wpa_supplicant could get stuck in SCANNING state when only the first
+ network for enabled (e.g., after 'wpa_cli select_network 0')
+ * winsvc: added support for configuring ctrl_interface parameters in
+ registry (ctrl_interface string value in
+ HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
+ required to enable control interface (previously, this was hardcoded
+ to be enabled)
+ * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
+ * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
+
+2006-06-20 - v0.5.4
+ * fixed build with CONFIG_STAKEY=y [Bug 143]
+ * added support for doing MLME (IEEE 802.11 management frame
+ processing) in wpa_supplicant when using Devicescape IEEE 802.11
+ stack (wireless-dev.git tree)
+ * added a new network block configuration option, fragment_size, to
+ configure the maximum EAP fragment size
+ * driver_ndis: Disable WZC automatically for the selected interface to
+ avoid conflicts with two programs trying to control the radio; WZC
+ will be re-enabled (if it was enabled originally) when wpa_supplicant
+ is terminated
+ * added an experimental TLSv1 client implementation
+ (CONFIG_TLS=internal) that can be used instead of an external TLS
+ library, e.g., to reduce total size requirement on systems that do
+ not include any TLS library by default (this is not yet complete;
+ basic functionality is there, but certificate validation is not yet
+ included)
+ * added PeerKey handshake implementation for IEEE 802.11e
+ direct link setup (DLS) to replace STAKey handshake
+ * fixed WPA PSK update through ctrl_iface for the case where the old
+ PSK was derived from an ASCII passphrase and the new PSK is set as
+ a raw PSK (hex string)
+ * added new configuration option for identifying which network block
+ was used (id_str in wpa_supplicant.conf; included on
+ WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
+ variable in wpa_cli action scripts; in addition WPA_ID variable is
+ set to the current unique identifier that wpa_supplicant assigned
+ automatically for the network and that can be used with
+ GET_NETWORK/SET_NETWORK ctrl_iface commands)
+ * wpa_cli action script is now called only when the connect/disconnect
+ status changes or when associating with a different network
+ * fixed configuration parser not to remove CCMP from group cipher list
+ if WPA-None (adhoc) is used (pairwise=NONE in that case)
+ * fixed integrated NDIS events processing not to hang the process due
+ to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
+ * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
+ draft-clancy-emu-eap-shared-secret-00.txt)
+ * added Microsoft Visual Studio 2005 solution and project files for
+ build wpa_supplicant for Windows (see vs2005 subdirectory)
+ * eloop_win: fixed unregistration of Windows events
+ * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
+ at the end of RSN pre-authentication and added unregistration of
+ a Windows event to avoid getting eloop_win stuck with an invalid
+ handle
+ * driver_ndis: added support for selecting AP based on BSSID
+ * added new environmental variable for wpa_cli action scripts:
+ WPA_CTRL_DIR is the current control interface directory
+ * driver_ndis: added support for using NDISUIO instead of WinPcap for
+ OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
+ l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
+ wpa_supplicant without requiring WinPcap; note that using NDISUIO
+ requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
+ only one application to open the device
+ * changed NDIS driver naming to only include device GUID, e.g.,
+ {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
+ specific \Device\NPF_ prefix before the GUID; the prefix is still
+ allowed for backwards compatibility, but it is not required anymore
+ when specifying the interface
+ * driver_ndis: re-initialize driver interface is the adapter is removed
+ and re-inserted [Bug 159]
+ * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
+ big endian hosts [Bug 146]
+
+2006-04-27 - v0.5.3
+ * fixed EAP-GTC response to include correct user identity when run as
+ phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
+ * driver_ndis: Fixed encryption mode configuration for unencrypted
+ networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
+ refused to associate with open networks) [Bug 106]
+ * driver_ndis: use BSSID OID polling to detect when IBSS network is
+ formed even when ndis_events code is included since some NDIS drivers
+ do not generate media connect events in IBSS mode
+ * config_winreg: allow global ctrl_interface parameter to be configured
+ in Windows registry
+ * config_winreg: added support for saving configuration data into
+ Windows registry
+ * added support for controlling network device operational state
+ (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
+ http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
+ that can use this information)
+ * driver_wext: added support for WE-21 change to SSID configuration
+ * driver_wext: fixed privacy configuration for static WEP keys mode
+ [Bug 140]
+ * added an optional driver_ops callback for MLME-SETPROTECTION.request
+ primitive
+ * added support for EAP-SAKE (no EAP method number allocated yet, so
+ this is using the same experimental type 255 as EAP-PSK)
+ * added support for dynamically loading EAP methods (.so files) instead
+ of requiring them to be statically linked in; this is disabled by
+ default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
+ on how to use this)
+
+2006-03-19 - v0.5.2
+ * do not try to use USIM APDUs when initializing PC/SC for SIM card
+ access for a network that has not enabled EAP-AKA
+ * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
+ v0.5.1 due to the new support for expanded EAP types)
+ * added support for generating EAP Expanded Nak
+ * try to fetch scan results once before requesting new scan when
+ starting up in ap_scan=1 mode (this can speed up initial association
+ a lot with, e.g., madwifi-ng driver)
+ * added support for receiving EAPOL frames from a Linux bridge
+ interface (-bbr0 on command line)
+ * fixed EAPOL re-authentication for sessions that used PMKSA caching
+ * changed EAP method registration to use a dynamic list of methods
+ instead of a static list generated at build time
+ * fixed PMKSA cache deinitialization not to use freed memory when
+ removing PMKSA entries
+ * fixed a memory leak in EAP-TTLS re-authentication
+ * reject WPA/WPA2 message 3/4 if it does not include any valid
+ WPA/RSN IE
+ * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
+ if the driver does not support SIOCSIWAUTH
+
+2006-01-29 - v0.5.1
+ * driver_test: added better support for multiple APs and STAs by using
+ a directory with sockets that include MAC address for each device in
+ the name (driver_param=test_dir=/tmp/test)
+ * added support for EAP expanded type (vendor specific EAP methods)
+ * added AP_SCAN command into ctrl_iface so that ap_scan configuration
+ option can be changed if needed
+ * wpa_cli/wpa_gui: skip non-socket files in control directory when
+ using UNIX domain sockets; this avoids selecting an incorrect
+ interface (e.g., a PID file could be in this directory, even though
+ use of this directory for something else than socket files is not
+ recommended)
+ * fixed TLS library deinitialization after RSN pre-authentication not
+ to disable TLS library for normal authentication
+ * driver_wext: Remove null-termination from SSID length if the driver
+ used it; some Linux drivers do this and they were causing problems in
+ wpa_supplicant not finding matching configuration block. This change
+ would break a case where the SSID actually ends in '\0', but that is
+ not likely to happen in real use.
+ * fixed PMKSA cache processing not to trigger deauthentication if the
+ current PMKSA cache entry is replaced with a valid new entry
+ * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
+ EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
+ ap_scan=2)
+
+2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
+ * added experimental STAKey handshake implementation for IEEE 802.11e
+ direct link setup (DLS); note: this is disabled by default in both
+ build and runtime configuration (can be enabled with CONFIG_STAKEY=y
+ and stakey=1)
+ * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
+ decrypt AT_ENCR_DATA attributes correctly
+ * fixed EAP-AKA to allow resynchronization within the same session
+ * made code closer to ANSI C89 standard to make it easier to port to
+ other C libraries and compilers
+ * started moving operating system or C library specific functions into
+ wrapper functions defined in os.h and implemented in os_*.c to make
+ code more portable
+ * wpa_supplicant can now be built with Microsoft Visual C++
+ (e.g., with the freely available Toolkit 2003 version or Visual
+ C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
+ example makefile for nmake
+ * added support for using Windows registry for command line parameters
+ (CONFIG_MAIN=main_winsvc) and configuration data
+ (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
+ contents; this version can be run both as a Windows service and as a
+ normal application; 'wpasvc.exe app' to start as applicant,
+ 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
+ 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
+ unregister a service
+ * made it possible to link ndis_events.exe functionality into
+ wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
+ * added better support for multiple control interface backends
+ (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
+ * fixed PC/SC code to use correct length for GSM AUTH command buffer
+ and to not use pioRecvPci with SCardTransmit() calls; these were not
+ causing visible problems with pcsc-lite, but Windows Winscard.dll
+ refused the previously used parameters; this fixes EAP-SIM and
+ EAP-AKA authentication using SIM/USIM card under Windows
+ * added new event loop implementation for Windows using
+ WaitForMultipleObject() instead of select() in order to allow waiting
+ for non-socket objects; this can be selected with
+ CONFIG_ELOOP=eloop_win in .config
+ * added support for selecting l2_packet implementation in .config
+ (CONFIG_L2_PACKET; following options are available now: linux, pcap,
+ winpcap, freebsd, none)
+ * added new l2_packet implementation for WinPcap
+ (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
+ reduce latency in EAPOL receive processing from about 100 ms to about
+ 3 ms
+ * added support for EAP-FAST key derivation using other ciphers than
+ RC4-128-SHA for authentication and AES128-SHA for provisioning
+ * added support for configuring CA certificate as DER file and as a
+ configuration blob
+ * fixed private key configuration as configuration blob and added
+ support for using PKCS#12 as a blob
+ * tls_gnutls: added support for using PKCS#12 files; added support for
+ session resumption
+ * added support for loading trusted CA certificates from Windows
+ certificate store: ca_cert="cert_store://<name>", where <name> is
+ likely CA (Intermediate CA certificates) or ROOT (root certificates)
+ * added C version of ndis_events.cpp and made it possible to build this
+ with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
+ easily on cross-compilation builds
+ * added wpasvc.exe into Windows binary release; this is an alternative
+ version of wpa_supplicant.exe with configuration backend using
+ Windows registry and with the entry point designed to run as a
+ Windows service
+ * integrated ndis_events.exe functionality into wpa_supplicant.exe and
+ wpasvc.exe and removed this additional tool from the Windows binary
+ release since it is not needed anymore
+ * load winscard.dll functions dynamically when building with MinGW
+ since MinGW does not yet include winscard library
+
+2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
+ * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
+ and WinPcap to receive frames sent to PAE group address
+ * disable EAP state machine when IEEE 802.1X authentication is not used
+ in order to get rid of bogus "EAP failed" messages
+ * fixed OpenSSL error reporting to go through all pending errors to
+ avoid confusing reports of old errors being reported at later point
+ during handshake
+ * fixed configuration file updating to not write empty variables
+ (e.g., proto or key_mgmt) that the file parser would not accept
+ * fixed ADD_NETWORK ctrl_iface command to use the same default values
+ for variables as empty network definitions read from config file
+ would get
+ * fixed EAP state machine to not discard EAP-Failure messages in many
+ cases (e.g., during TLS handshake)
+ * fixed a infinite loop in private key reading if the configured file
+ cannot be parsed successfully
+ * driver_madwifi: added support for madwifi-ng
+ * wpa_gui: do not display password/PSK field contents
+ * wpa_gui: added CA certificate configuration
+ * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
+ * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
+ the new AP is using different WPA/RSN IE
+ * use longer timeout for IEEE 802.11 association to avoid problems with
+ drivers that may take more than five second to associate
+
+2005-10-27 - v0.4.6
+ * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
+ RSN IE, but WPA IE would match with wpa_supplicant configuration
+ * added support for named configuration blobs in order to avoid having
+ to use file system for external files (e.g., certificates);
+ variables can be set to "blob://<blob name>" instead of file path to
+ use a named blob; supported fields: pac_file, client_cert,
+ private_key
+ * fixed RSN pre-authentication (it was broken in the clean up of WPA
+ state machine interface in v0.4.5)
+ * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
+ sure the driver configures broadcast decryption correctly
+ * added ca_path (and ca_path2) configuration variables that can be used
+ to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
+ system-wide trusted CA list
+ * added support for starting wpa_supplicant without a configuration
+ file (-C argument must be used to set ctrl_interface parameter for
+ this case; in addition, -p argument can be used to provide
+ driver_param; these new arguments can also be used with a
+ configuration to override the values from the configuration)
+ * added global control interface that can be optionally used for adding
+ and removing network interfaces dynamically (-g command line argument
+ for both wpa_supplicant and wpa_cli) without having to restart
+ wpa_supplicant process
+ * wpa_gui:
+ - try to save configuration whenever something is modified
+ - added WEP key configuration
+ - added possibility to edit the current network configuration
+ * driver_ndis: fixed driver polling not to increase frequency on each
+ received EAPOL frame due to incorrectly cancelled timeout
+ * added simple configuration file examples (in examples subdirectory)
+ * fixed driver_wext.c to filter wireless events based on ifindex to
+ avoid interfaces receiving events from other interfaces
+ * delay sending initial EAPOL-Start couple of seconds to speed up
+ authentication for the most common case of Authenticator starting
+ EAP authentication immediately after association
+
+2005-09-25 - v0.4.5
+ * added a workaround for clearing keys with ndiswrapper to allow
+ roaming from WPA enabled AP to plaintext one
+ * added docbook documentation (doc/docbook) that can be used to
+ generate, e.g., man pages
+ * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
+ PF_PACKET in order to prepare for network devices that do not use
+ Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
+ * use receipt of EAPOL-Key frame as a lower layer success indication
+ for EAP state machine to allow recovery from dropped EAP-Success
+ frame
+ * cleaned up internal EAPOL frame processing by not including link
+ layer (Ethernet) header during WPA and EAPOL/EAP processing; this
+ header is added only when transmitted the frame; this makes it easier
+ to use wpa_supplicant on link layers that use different header than
+ Ethernet
+ * updated EAP-PSK to use draft 9 by default since this can now be
+ tested with hostapd; removed support for draft 3, including
+ server_nai configuration option from network blocks
+ * driver_wired: add PAE address to the multicast address list in order
+ to be able to receive EAPOL frames with drivers that do not include
+ these multicast addresses by default
+ * driver_wext: add support for WE-19
+ * added support for multiple configuration backends (CONFIG_BACKEND
+ option); currently, only 'file' is supported (i.e., the format used
+ in wpa_supplicant.conf)
+ * added support for updating configuration ('wpa_cli save_config');
+ this is disabled by default and can be enabled with global
+ update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
+ and wpa_gui to store the configuration changes in a permanent store
+ * added GET_NETWORK ctrl_iface command
+ (e.g., 'wpa_cli get_network 0 ssid')
+
+2005-08-21 - v0.4.4
+ * replaced OpenSSL patch for EAP-FAST support
+ (openssl-tls-extensions.patch) with a more generic and correct
+ patch (the new patch is not compatible with the previous one, so the
+ OpenSSL library will need to be patched with the new patch in order
+ to be able to build wpa_supplicant with EAP-FAST support)
+ * added support for using Windows certificate store (through CryptoAPI)
+ for client certificate and private key operations (EAP-TLS)
+ (see wpa_supplicant.conf for more information on how to configure
+ this with private_key)
+ * ported wpa_gui to Windows
+ * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
+ built with the open source version of the Qt4 for Windows
+ * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
+ with drivers that do not support WPA
+ * ndis_events: fixed Windows 2000 support
+ * added support for enabling/disabling networks from the list of all
+ configured networks ('wpa_cli enable_network <network id>' and
+ 'wpa_cli disable_network <network id>')
+ * added support for adding and removing network from the current
+ configuration ('wpa_cli add_network' and 'wpa_cli remove_network
+ <network id>'); added networks are disabled by default and they can
+ be enabled with enable_network command once the configuration is done
+ for the new network; note: configuration file is not yet updated, so
+ these new networks are lost when wpa_supplicant is restarted
+ * added support for setting network configuration parameters through
+ the control interface, for example:
+ wpa_cli set_network 0 ssid "\"my network\""
+ * fixed parsing of strings that include both " and # within double
+ quoted area (e.g., "start"#end")
+ * added EAP workaround for PEAP session resumption: allow outer,
+ i.e., not tunneled, EAP-Success to terminate session since; this can
+ be disabled with eap_workaround=0
+ (this was allowed for PEAPv1 before, but now it is also allowed for
+ PEAPv0 since at least one RADIUS authentication server seems to be
+ doing this for PEAPv0, too)
+ * wpa_gui: added preliminary support for adding new networks to the
+ wpa_supplicant configuration (double click on the scan results to
+ open network configuration)
+
+2005-06-26 - v0.4.3
+ * removed interface for external EAPOL/EAP supplicant (e.g.,
+ Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
+ anymore and is unlikely to be used by anyone
+ * driver_ndis: fixed WinPcap 3.0 support
+ * fixed build with CONFIG_DNET_PCAP=y on Linux
+ * l2_packet: moved different implementations into separate files
+ (l2_packet_*.c)
+
+2005-06-12 - v0.4.2
+ * driver_ipw: updated driver structures to match with ipw2200-1.0.4
+ (note: ipw2100-1.1.0 is likely to require an update to work with
+ this)
+ * added support for using ap_scan=2 mode with multiple network blocks;
+ wpa_supplicant will go through the networks one by one until the
+ driver reports a successful association; this uses the same order for
+ networks as scan_ssid=1 scans, i.e., the priority field is ignored
+ and the network block order in the file is used instead
+ * fixed a potential issue in RSN pre-authentication ending up using
+ freed memory if pre-authentication times out
+ * added support for matching alternative subject name extensions of the
+ authentication server certificate; new configuration variables
+ altsubject_match and altsubject_match2
+ * driver_ndis: added support for IEEE 802.1X authentication with wired
+ NDIS drivers
+ * added support for querying private key password (EAP-TLS) through the
+ control interface (wpa_cli/wpa_gui) if one is not included in the
+ configuration file
+ * driver_broadcom: fixed couple of memory leaks in scan result
+ processing
+ * EAP-PAX is now registered as EAP type 46
+ * fixed EAP-PAX MAC calculation
+ * fixed EAP-PAX CK and ICK key derivation
+ * added support for using password with EAP-PAX (as an alternative to
+ entering key with eappsk); SHA-1 hash of the password will be used as
+ the key in this case
+ * added support for arbitrary driver interface parameters through the
+ configuration file with a new driver_param field; this adds a new
+ driver_ops function set_param()
+ * added possibility to override l2_packet module with driver interface
+ API (new send_eapol handler); this can be used to implement driver
+ specific TX/RX functions for EAPOL frames
+ * fixed ctrl_interface_group processing for the case where gid is
+ entered as a number, not group name
+ * driver_test: added support for testing hostapd with wpa_supplicant
+ by using test driver interface without any kernel drivers or network
+ cards
+
+2005-05-22 - v0.4.1
+ * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
+ packets to be encrypted; this was apparently broken by the changed
+ ioctl order in v0.4.0
+ * driver_madwifi: added preliminary support for compiling against 'BSD'
+ branch of madwifi CVS tree
+ * added support for EAP-MSCHAPv2 password retries within the same EAP
+ authentication session
+ * added support for password changes with EAP-MSCHAPv2 (used when the
+ password has expired)
+ * added support for reading additional certificates from PKCS#12 files
+ and adding them to the certificate chain
+ * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
+ were used
+ * fixed a possible double free in EAP-TTLS fast-reauthentication when
+ identity or password is entered through control interface
+ * display EAP Notification messages to user through control interface
+ with "CTRL-EVENT-EAP-NOTIFICATION" prefix
+ * added GUI version of wpa_cli, wpa_gui; this is not build
+ automatically with 'make'; use 'make wpa_gui' to build (this requires
+ Qt development tools)
+ * added 'disconnect' command to control interface for setting
+ wpa_supplicant in state where it will not associate before
+ 'reassociate' command has been used
+ * added support for selecting a network from the list of all configured
+ networks ('wpa_cli select_network <network id>'; this disabled all
+ other networks; to re-enable, 'wpa_cli select_network any')
+ * added support for getting scan results through control interface
+ * added EAP workaround for PEAPv1 session resumption: allow outer,
+ i.e., not tunneled, EAP-Success to terminate session since; this can
+ be disabled with eap_workaround=0
+
+2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
+ * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
+ used to reduce the size of the wpa_supplicant considerably if
+ debugging code is not needed
+ * fixed EAPOL-Key validation to drop packets with invalid Key Data
+ Length; such frames could have crashed wpa_supplicant due to buffer
+ overflow
+ * added support for wired authentication (IEEE 802.1X on wired
+ Ethernet); driver interface 'wired'
+ * obsoleted set_wpa() handler in the driver interface API (it can be
+ replaced by moving enable/disable functionality into init()/deinit())
+ (calls to set_wpa() are still present for backwards compatibility,
+ but they may be removed in the future)
+ * driver_madwifi: fixed association in plaintext mode
+ * modified the EAP workaround that accepts EAP-Success with incorrect
+ Identifier to be even less strict about verification in order to
+ interoperate with some authentication servers
+ * added support for sending TLS alerts
+ * added support for 'any' SSID wildcard; if ssid is not configured or
+ is set to an empty string, any SSID will be accepted for non-WPA AP
+ * added support for asking PIN (for SIM) from frontends (e.g.,
+ wpa_cli); if a PIN is needed, but not included in the configuration
+ file, a control interface request is sent and EAP processing is
+ delayed until the PIN is available
+ * added support for using external devices (e.g., a smartcard) for
+ private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
+ new wpa_supplicant.conf variables:
+ - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
+ - network: engine, engine_id, key_id
+ * added experimental support for EAP-PAX
+ * added monitor mode for wpa_cli (-a<path to a program to run>) that
+ allows external commands (e.g., shell scripts) to be run based on
+ wpa_supplicant events, e.g., when authentication has been completed
+ and data connection is ready; other related wpa_cli arguments:
+ -B (run in background), -P (write PID file); wpa_supplicant has a new
+ command line argument (-W) that can be used to make it wait until a
+ control interface command is received in order to avoid missing
+ events
+ * added support for opportunistic WPA2 PMKSA key caching (disabled by
+ default, can be enabled with proactive_key_caching=1)
+ * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
+ Authenticator rejects PMKSA caching attempt and the driver is not
+ using assoc_info events
+ * added -P<pid file> argument for wpa_supplicant to write the current
+ process id into a file
+
+2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
+ * added new phase1 option parameter, include_tls_length=1, to force
+ wpa_supplicant to add TLS Message Length field to all TLS messages
+ even if the packet is not fragmented; this may be needed with some
+ authentication servers
+ * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
+ using drivers that take care of AP selection (e.g., when using
+ ap_scan=2)
+ * fixed reprocessing of pending request after ctrl_iface requests for
+ identity/password/otp
+ * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
+ EAP-PEAP and EAP-TTLS
+ * all drivers using driver_wext: set interface up and select Managed
+ mode when starting wpa_supplicant; set interface down when exiting
+ * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
+ ipw2100 and ipw2200; please note that this also changed the
+ configuration variable in .config to CONFIG_DRIVER_IPW
+
+2005-01-24 - v0.3.6
+ * fixed a busy loop introduced in v0.3.5 for scan result processing
+ when no matching AP is found
+
+2005-01-23 - v0.3.5
+ * added a workaround for an interoperability issue with a Cisco AP
+ when using WPA2-PSK
+ * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
+ WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
+ retransmission of dropped frames)
+ * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
+ (e.g., segfault when processing EAPOL-Key frames)
+ * fixed EAP workaround and fast reauthentication configuration for
+ RSN pre-authentication; previously these were disabled and
+ pre-authentication would fail if the used authentication server
+ requires EAP workarounds
+ * added support for blacklisting APs that fail or timeout
+ authentication in ap_scan=1 mode so that all APs are tried in cases
+ where the ones with strongest signal level are failing authentication
+ * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
+ authentication attempt
+ * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
+ in the previous authentication (previously, only Phase 1 success was
+ verified)
+
+2005-01-09 - v0.3.4
+ * added preliminary support for IBSS (ad-hoc) mode configuration
+ (mode=1 in network block); this included a new key_mgmt mode
+ WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
+ key management; see wpa_supplicant.conf for more details and an
+ example on how to configure this (note: this is currently implemented
+ only for driver_hostapd.c, but the changes should be trivial to add
+ in associate() handler for other drivers, too (assuming the driver
+ supports WPA-None)
+ * added preliminary port for native Windows (i.e., no cygwin) using
+ mingw
+
+2005-01-02 - v0.3.3
+ * added optional support for GNU Readline and History Libraries for
+ wpa_cli (CONFIG_READLINE)
+ * cleaned up EAP state machine <-> method interface and number of
+ small problems with error case processing not terminating on
+ EAP-Failure but waiting for timeout
+ * added couple of workarounds for interoperability issues with a
+ Cisco AP when using WPA2
+ * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
+ Note: This requires a patch for openssl to add support for TLS
+ extensions and number of workarounds for operations without
+ certificates. Proof of concept type of experimental patch is
+ included in openssl-tls-extensions.patch.
+
+2004-12-19 - v0.3.2
+ * fixed private key loading for cases where passphrase is not set
+ * fixed Windows/cygwin L2 packet handler freeing; previous version
+ could cause a segfault when RSN pre-authentication was completed
+ * added support for PMKSA caching with drivers that generate RSN IEs
+ (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
+ but similar code can be easily added to driver_ndiswrapper.c once
+ ndiswrapper gets full support for RSN PMKSA caching
+ * improved recovery from PMKID mismatches by requesting full EAP
+ authentication in case of failed PMKSA caching attempt
+ * driver_ndis: added support for NDIS NdisMIncidateStatus() events
+ (this requires that ndis_events is ran while wpa_supplicant is
+ running)
+ * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
+ * added support for driver interfaces to replace the interface name
+ based on driver/OS specific mapping, e.g., in case of driver_ndis,
+ this allows the beginning of the adapter description to be used as
+ the interface name
+ * added support for CR+LF (Windows-style) line ends in configuration
+ file
+ * driver_ndis: enable radio before starting scanning, disable radio
+ when exiting
+ * modified association event handler to set portEnabled = FALSE before
+ clearing port Valid in order to reset EAP state machine and avoid
+ problems with new authentication getting ignored because of state
+ machines ending up in AUTHENTICATED/SUCCESS state based on old
+ information
+ * added support for driver events to add PMKID candidates in order to
+ allow drivers to give priority to most likely roaming candidates
+ * driver_hostap: moved PrivacyInvoked configuration to associate()
+ function so that this will not be set for plaintext connections
+ * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
+ interface can distinguish plaintext and IEEE 802.1X (no WPA)
+ authentication
+ * fixed static WEP key configuration to use broadcast/default type for
+ all keys (previously, the default TX key was configured as pairwise/
+ unicast key)
+ * driver_ndis: added legacy WPA capability detection for non-WPA2
+ drivers
+ * added support for setting static WEP keys for IEEE 802.1X without
+ dynamic WEP keying (eapol_flags=0)
+
+2004-12-12 - v0.3.1
+ * added support for reading PKCS#12 (PFX) files (as a replacement for
+ PEM/DER) to get certificate and private key (CONFIG_PKCS12)
+ * fixed compilation with CONFIG_PCSC=y
+ * added new ap_scan mode, ap_scan=2, for drivers that take care of
+ association, but need to be configured with security policy and SSID,
+ e.g., ndiswrapper and NDIS driver; this mode should allow such
+ drivers to work with hidden SSIDs and optimized roaming; when
+ ap_scan=2 is used, only the first network block in the configuration
+ file is used and this configuration should have explicit security
+ policy (i.e., only one option in the lists) for key_mgmt, pairwise,
+ group, proto variables
+ * added experimental port of wpa_supplicant for Windows
+ - driver_ndis.c driver interface (NDIS OIDs)
+ - currently, this requires cygwin and WinPcap
+ - small utility, win_if_list, can be used to get interface name
+ * control interface can now be removed at build time; add
+ CONFIG_CTRL_IFACE=y to .config to maintain old functionality
+ * optional Xsupplicant interface can now be removed at build time;
+ (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
+ * added auth_alg to driver interface associate() parameters to make it
+ easier for drivers to configure authentication algorithm as part of
+ the association
+
+2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
+ * driver_broadcom: added new driver interface for Broadcom wl.o driver
+ (a generic driver for Broadcom IEEE 802.11a/g cards)
+ * wpa_cli: fixed parsing of -p <path> command line argument
+ * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
+ ACK, not tunneled EAP-Success (of which only the first byte was
+ actually send due to a bug in previous code); this seems to
+ interoperate with most RADIUS servers that implements PEAPv1
+ * PEAPv1: added support for terminating PEAP authentication on tunneled
+ EAP-Success message; this can be configured by adding
+ peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
+ (some RADIUS servers require this whereas others require a tunneled
+ reply
+ * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
+ the old label for key derivation; previously, the default was 1,
+ but it looks like most existing PEAPv1 implementations use the old
+ label which is thus more suitable default option
+ * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
+ * fixed parsing of wep_tx_keyidx
+ * added support for configuring list of allowed Phase 2 EAP types
+ (for both EAP-PEAP and EAP-TTLS) instead of only one type
+ * added support for configuring IEEE 802.11 authentication algorithm
+ (auth_alg; mainly for using Shared Key authentication with static
+ WEP keys)
+ * added support for EAP-AKA (with UMTS SIM)
+ * fixed couple of errors in PCSC handling that could have caused
+ random-looking errors for EAP-SIM
+ * added support for EAP-SIM pseudonyms and fast re-authentication
+ * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
+ session resumption)
+ * added support for EAP-SIM with two challanges
+ (phase1="sim_min_num_chal=3" can be used to require three challenges)
+ * added support for configuring DH/DSA parameters for an ephemeral DH
+ key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
+ dh_file and dh_file2 (phase 2); this adds support for using DSA keys
+ and optional DH key exchange to achieve forward secracy with RSA keys
+ * added support for matching subject of the authentication server
+ certificate with a substring when using EAP-TLS/PEAP/TTLS; new
+ configuration variables subject_match and subject_match2
+ * changed SSID configuration in driver_wext.c (used by many driver
+ interfaces) to use ssid_len+1 as the length for SSID since some Linux
+ drivers expect this
+ * fixed couple of unaligned reads in scan result parsing to fix WPA
+ connection on some platforms (e.g., ARM)
+ * added driver interface for Intel ipw2100 driver
+ * added support for LEAP with WPA
+ * added support for larger scan results report (old limit was 4 kB of
+ data, i.e., about 35 or so APs) when using Linux wireless extensions
+ v17 or newer
+ * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
+ only if there is a PMKSA cache entry for the current AP
+ * fixed error handling for case where reading of scan results fails:
+ must schedule a new scan or wpa_supplicant will remain waiting
+ forever
+ * changed debug output to remove shared password/key material by
+ default; all key information can be included with -K command line
+ argument to match the previous behavior
+ * added support for timestamping debug log messages (disabled by
+ default, can be enabled with -t command line argument)
+ * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
+ if keys are not configured to be used; this fixes IEEE 802.1X mode
+ with drivers that use this information to configure whether Privacy
+ bit can be in Beacon frames (e.g., ndiswrapper)
+ * avoid clearing driver keys if no keys have been configured since last
+ key clear request; this seems to improve reliability of group key
+ handshake for ndiswrapper & NDIS driver which seems to be suffering
+ of some kind of timing issue when the keys are cleared again after
+ association
+ * changed driver interface API:
+ - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
+ version is being used (now, this is set to 2; previously, it was
+ not defined)
+ - pass pointer to private data structure to all calls
+ - the new API is not backwards compatible; all in-tree driver
+ interfaces has been converted to the new API
+ * added support for controlling multiple interfaces (radios) per
+ wpa_supplicant process; each interface needs to be listed on the
+ command line (-c, -i, -D arguments) with -N as a separator
+ (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
+ * added a workaround for EAP servers that incorrectly use same Id for
+ sequential EAP packets
+ * changed libpcap/libdnet configuration to use .config variable,
+ CONFIG_DNET_PCAP, instead of requiring Makefile modification
+ * improved downgrade attack detection in IE verification of msg 3/4:
+ verify both WPA and RSN IEs, if present, not only the selected one;
+ reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
+ Probe Response frame, and RSN is enabled in wpa_supplicant
+ configuration
+ * fixed WPA msg 3/4 processing to allow Key Data field contain other
+ IEs than just one WPA IE
+ * added support for FreeBSD and driver interface for the BSD net80211
+ layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
+ required kernel mods have not yet been committed
+ * made EAP workarounds configurable; enabled by default, can be
+ disabled with network block option eap_workaround=0
+
+2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
+ * resolved couple of interoperability issues with EAP-PEAPv1 and
+ Phase 2 (inner EAP) fragment reassembly
+ * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
+ AP is using non-zero key index for the unicast key and key index zero
+ for the broadcast key
+ * driver_hostap: fixed IEEE 802.1X WEP key updates and
+ re-authentication by allowing unencrypted EAPOL frames when not using
+ WPA
+ * added a new driver interface, 'wext', which uses only standard,
+ driver independent functionality in Linux wireless extensions;
+ currently, this can be used only for non-WPA IEEE 802.1X mode, but
+ eventually, this is to be extended to support full WPA/WPA2 once
+ Linux wireless extensions get support for this
+ * added support for mode in which the driver is responsible for AP
+ scanning and selection; this is disabled by default and can be
+ enabled with global ap_scan=0 variable in wpa_supplicant.conf;
+ this mode can be used, e.g., with generic 'wext' driver interface to
+ use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
+ supporting wireless extensions.
+ * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
+ operation with an AP that does not include SSID in the Beacon frames)
+ * added support for new EAP authentication methods:
+ EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
+ * added support for asking one-time-passwords from frontends (e.g.,
+ wpa_cli); this 'otp' command works otherwise like 'password' command,
+ but the password is used only once and the frontend will be asked for
+ a new password whenever a request from authenticator requires a
+ password; this can be used with both EAP-OTP and EAP-GTC
+ * changed wpa_cli to automatically re-establish connection so that it
+ does not need to be re-started when wpa_supplicant is terminated and
+ started again
+ * improved user data (identity/password/otp) requests through
+ frontends: process pending EAPOL packets after getting new
+ information so that full authentication does not need to be
+ restarted; in addition, send pending requests again whenever a new
+ frontend is attached
+ * changed control frontends to use a new directory for socket files to
+ make it easier for wpa_cli to automatically select between interfaces
+ and to provide access control for the control interface;
+ wpa_supplicant.conf: ctrl_interface is now a path
+ (/var/run/wpa_supplicant is the recommended path) and
+ ctrl_interface_group can be used to select which group gets access to
+ the control interface;
+ wpa_cli: by default, try to connect to the first interface available
+ in /var/run/wpa_supplicant; this path can be overriden with -p option
+ and an interface can be selected with -i option (i.e., in most common
+ cases, wpa_cli does not need to get any arguments)
+ * added support for LEAP
+ * added driver interface for Linux ndiswrapper
+ * added priority option for network blocks in the configuration file;
+ this allows networks to be grouped based on priority (the scan
+ results are searched for matches with network blocks in this order)
+
+2004-06-20 - v0.2.3
+ * sort scan results to improve AP selection
+ * fixed control interface socket removal for some error cases
+ * improved scan requesting and authentication timeout
+ * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
+ TLS processing
+ * PEAP version can now be forced with phase1="peapver=<ver>"
+ (mostly for testing; by default, the highest version supported by
+ both the Supplicant and Authentication Server is selected
+ automatically)
+ * added support for madwifi driver (Atheros ar521x)
+ * added a workaround for cases where AP sets Install Tx/Rx bit for
+ WPA Group Key messages when pairwise keys are used (without this,
+ the Group Key would be used for Tx and the AP would drop frames
+ from the station)
+ * added GSM SIM/USIM interface for GSM authentication algorithm for
+ EAP-SIM; this requires pcsc-lite
+ * added support for ATMEL AT76C5XXx driver
+ * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
+ does not include key data in the EAPOL-Key frame (i.e., part of
+ EAP keying material is used as data encryption key)
+ * added support for using plaintext and static WEP networks
+ (key_mgmt=NONE)
+
+2004-05-31 - v0.2.2
+ * added support for new EAP authentication methods:
+ EAP-TTLS/EAP-MD5-Challenge
+ EAP-TTLS/EAP-GTC
+ EAP-TTLS/EAP-MSCHAPv2
+ EAP-TTLS/EAP-TLS
+ EAP-TTLS/MSCHAPv2
+ EAP-TTLS/MSCHAP
+ EAP-TTLS/PAP
+ EAP-TTLS/CHAP
+ EAP-PEAP/TLS
+ EAP-PEAP/GTC
+ EAP-PEAP/MD5-Challenge
+ EAP-GTC
+ EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
+ * added support for anonymous identity (to be used when identity is
+ sent in plaintext; real identity will be used within TLS protected
+ tunnel (e.g., with EAP-TTLS)
+ * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
+ * added support for requesting identity and password information using
+ control interface; in other words, the password for EAP-PEAP or
+ EAP-TTLS does not need to be included in the configuration file since
+ a frontand (e.g., wpa_cli) can ask it from the user
+ * improved RSN pre-authentication to use a candidate list and process
+ all candidates from each scan; not only one per scan
+ * fixed RSN IE and WPA IE capabilities field parsing
+ * ignore Tx bit in GTK IE when Pairwise keys are used
+ * avoid making new scan requests during IEEE 802.1X negotiation
+ * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
+ with TLS support (this replaces the included implementation with
+ library code to save about 8 kB since the library code is needed
+ anyway for TLS)
+ * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
+ (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
+
+2004-05-06 - v0.2.1
+ * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
+ Supplicant
+ - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
+ - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
+ - EAP-MD5 (cannot be used with WPA-RADIUS)
+ [draft-ietf-eap-rfc2284bis-09.txt]
+ - EAP-TLS [RFC 2716]
+ - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
+ - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
+ [draft-kamath-pppext-eap-mschapv2-00.txt]
+ (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
+ default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
+ - new configuration file options: eap, identity, password, ca_cert,
+ client_cert, privatekey, private_key_passwd
+ - Xsupplicant is not required anymore, but it can be used by
+ disabling the internal IEEE 802.1X Supplicant with -e command line
+ option
+ - this code is not included in the default build; Makefile need to
+ be edited for this (uncomment lines for selected functionality)
+ - EAP-TLS and EAP-PEAP require openssl libraries
+ * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
+ * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
+ (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
+ EAPOL-Key frames instead of WPA key handshakes)
+ * added support for IEEE 802.11i/RSN (WPA2)
+ - improved PTK Key Handshake
+ - PMKSA caching, pre-authentication
+ * fixed wpa_supplicant to ignore possible extra data after WPA
+ EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
+ TPTK' error from message 3 of 4-Way Handshake in case the AP
+ includes extra data after the EAPOL-Key)
+ * added interface for external programs (frontends) to control
+ wpa_supplicant
+ - CLI example (wpa_cli) with interactive mode and command line
+ mode
+ - replaced SIGUSR1 status/statistics with the new control interface
+ * made some feature compile time configurable
+ - .config file for make
+ - driver interfaces (hostap, hermes, ..)
+ - EAPOL/EAP functions
+
+2004-02-15 - v0.2.0
+ * Initial version of wpa_supplicant

+
+Features
+--------
+
+Supported WPA/IEEE 802.11i features:
+- WPA-PSK ("WPA-Personal")
+- WPA with EAP (e.g., with RADIUS authentication server) ("WPA-Enterprise")
+ Following authentication methods are supported with an integrate IEEE 802.1X
+ Supplicant:
+ * EAP-TLS
+ * EAP-PEAP/MSCHAPv2 (both PEAPv0 and PEAPv1)
+ * EAP-PEAP/TLS (both PEAPv0 and PEAPv1)
+ * EAP-PEAP/GTC (both PEAPv0 and PEAPv1)
+ * EAP-PEAP/OTP (both PEAPv0 and PEAPv1)
+ * EAP-PEAP/MD5-Challenge (both PEAPv0 and PEAPv1)
+ * EAP-TTLS/EAP-MD5-Challenge
+ * EAP-TTLS/EAP-GTC
+ * EAP-TTLS/EAP-OTP
+ * EAP-TTLS/EAP-MSCHAPv2
+ * EAP-TTLS/EAP-TLS
+ * EAP-TTLS/MSCHAPv2
+ * EAP-TTLS/MSCHAP
+ * EAP-TTLS/PAP
+ * EAP-TTLS/CHAP
+ * EAP-SIM
+ * EAP-AKA
+ * EAP-PSK
+ * EAP-PAX
+ * EAP-SAKE
+ * EAP-GPSK
+ * LEAP (note: requires special support from the driver for IEEE 802.11
+ authentication)
+ (following methods are supported, but since they do not generate keying
+ material, they cannot be used with WPA or IEEE 802.1X WEP keying)
+ * EAP-MD5-Challenge
+ * EAP-MSCHAPv2
+ * EAP-GTC
+ * EAP-OTP
+- key management for CCMP, TKIP, WEP104, WEP40
+- RSN/WPA2 (IEEE 802.11i)
+ * pre-authentication
+ * PMKSA caching
+
+Supported TLS/crypto libraries:
+- OpenSSL (default)
+- GnuTLS
+
+Internal TLS/crypto implementation (optional):
+- can be used in place of an external TLS/crypto library
+- TLSv1
+- X.509 certificate processing
+- PKCS #1
+- ASN.1
+- RSA
+- bignum
+- minimal size (ca. 50 kB binary, parts of which are already needed for WPA;
+ TLSv1/X.509/ASN.1/RSA/bignum parts are about 25 kB on x86)
+
+
+Requirements
+------------
+
+Current hardware/software requirements:
+- Linux kernel 2.4.x or 2.6.x with Linux Wireless Extensions v15 or newer
+- FreeBSD 6-CURRENT
+- NetBSD-current
+- Microsoft Windows with WinPcap (at least WinXP, may work with other versions)
+- drivers:
+ Linux drivers that support WPA/WPA2 configuration with the generic
+ Linux wireless extensions (WE-18 or newer). Even though there are
+ number of driver specific interface included in wpa_supplicant, please
+ note that Linux drivers are moving to use generic wireless extensions
+ and driver_wext (-Dwext on wpa_supplicant command line) should be the
+ default option to start with before falling back to driver specific
+ interface.
+
+ Host AP driver for Prism2/2.5/3 (development snapshot/v0.2.x)
+ (http://hostap.epitest.fi/)
+ Driver need to be set in Managed mode ('iwconfig wlan0 mode managed').
+ Please note that station firmware version needs to be 1.7.0 or newer
+ to work in WPA mode.
+
+ Linuxant DriverLoader (http://www.linuxant.com/driverloader/)
+ with Windows NDIS driver for your wlan card supporting WPA.
+
+ Agere Systems Inc. Linux Driver
+ (http://www.agere.com/support/drivers/)
+ Please note that the driver interface file (driver_hermes.c) and
+ hardware specific include files are not included in the
+ wpa_supplicant distribution. You will need to copy these from the
+ source package of the Agere driver.
+
+ madwifi driver for cards based on Atheros chip set (ar521x)
+ (http://sourceforge.net/projects/madwifi/)
+ Please note that you will need to modify the wpa_supplicant .config
+ file to use the correct path for the madwifi driver root directory
+ (CFLAGS += -I../madwifi/wpa line in example defconfig).
+
+ ATMEL AT76C5XXx driver for USB and PCMCIA cards
+ (http://atmelwlandriver.sourceforge.net/).
+
+ Linux ndiswrapper (http://ndiswrapper.sourceforge.net/) with
+ Windows NDIS driver.
+
+ Broadcom wl.o driver
+ This is a generic Linux driver for Broadcom IEEE 802.11a/g cards.
+ However, it is proprietary driver that is not publicly available
+ except for couple of exceptions, mainly Broadcom-based APs/wireless
+ routers that use Linux. The driver binary can be downloaded, e.g.,
+ from Linksys support site (http://www.linksys.com/support/gpl.asp)
+ for Linksys WRT54G. The GPL tarball includes cross-compiler and
+ the needed header file, wlioctl.h, for compiling wpa_supplicant.
+ This driver support in wpa_supplicant is expected to work also with
+ other devices based on Broadcom driver (assuming the driver includes
+ client mode support).
+
+ Intel ipw2100 driver
+ (http://sourceforge.net/projects/ipw2100/)
+
+ Intel ipw2200 driver
+ (http://sourceforge.net/projects/ipw2200/)
+
+ In theory, any driver that supports Linux wireless extensions can be
+ used with IEEE 802.1X (i.e., not WPA) when using ap_scan=0 option in
+ configuration file.
+
+ Wired Ethernet drivers (with ap_scan=0)
+
+ BSD net80211 layer (e.g., Atheros driver)
+ At the moment, this is for FreeBSD 6-CURRENT branch and NetBSD-current.
+
+ Windows NDIS
+ The current Windows port requires WinPcap (http://winpcap.polito.it/).

+
+wpa_supplicant was designed to be portable for different drivers and
+operating systems. Hopefully, support for more wlan cards and OSes will be
+added in the future. See developer's documentation
+(http://hostap.epitest.fi/wpa_supplicant/devel/) for more information about the
+design of wpa_supplicant and porting to other drivers. One main goal
+is to add full WPA/WPA2 support to Linux wireless extensions to allow
+new drivers to be supported without having to implement new
+driver-specific interface code in wpa_supplicant.
+
+Optional libraries for layer2 packet processing:
+- libpcap (tested with 0.7.2, most relatively recent versions assumed to work,
+ this is likely to be available with most distributions,
+ http://tcpdump.org/)
+- libdnet (tested with v1.4, most versions assumed to work,
+ http://libdnet.sourceforge.net/)
+
+These libraries are _not_ used in the default Linux build. Instead,
+internal Linux specific implementation is used. libpcap/libdnet are
+more portable and they can be used by adding CONFIG_L2_PACKET=pcap into
+.config. They may also be selected automatically for other operating
+systems. In case of Windows builds, WinPcap is used by default
+(CONFIG_L2_PACKET=winpcap).
+
+
+Optional libraries for EAP-TLS, EAP-PEAP, and EAP-TTLS:
+- OpenSSL (tested with 0.9.7c and 0.9.7d, and 0.9.8 versions; assumed to
+ work with most relatively recent versions; this is likely to be
+ available with most distributions, http://www.openssl.org/)
+- GnuTLS
+- internal TLSv1 implementation
+
+TLS options for EAP-FAST:
+- OpenSSL 0.9.8d _with_ openssl-0.9.8d-tls-extensions.patch applied
+ (i.e., the default OpenSSL package does not include support for
+ extensions needed for EAP-FAST)
+- internal TLSv1 implementation
+
+One of these libraries is needed when EAP-TLS, EAP-PEAP, EAP-TTLS, or
+EAP-FAST support is enabled. WPA-PSK mode does not require this or EAPOL/EAP
+implementation. A configuration file, .config, for compilation is
+needed to enable IEEE 802.1X/EAPOL and EAP methods. Note that EAP-MD5,
+EAP-GTC, EAP-OTP, and EAP-MSCHAPV2 cannot be used alone with WPA, so
+they should only be enabled if testing the EAPOL/EAP state
+machines. However, there can be used as inner authentication
+algorithms with EAP-PEAP and EAP-TTLS.
+
+See Building and installing section below for more detailed
+information about the wpa_supplicant build time configuration.
+
+
+
+WPA
+---
+
+The original security mechanism of IEEE 802.11 standard was not
+designed to be strong and has proven to be insufficient for most
+networks that require some kind of security. Task group I (Security)
+of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
+to address the flaws of the base standard and has in practice
+completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
+802.11 standard was approved in June 2004 and published in July 2004.
+
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
+IEEE 802.11i work (draft 3.0) to define a subset of the security
+enhancements that can be implemented with existing wlan hardware. This
+is called Wi-Fi Protected Access<TM> (WPA). This has now become a
+mandatory component of interoperability testing and certification done
+by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
+site (http://www.wi-fi.org/OpenSection/protected_access.asp).
+
+IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
+for protecting wireless networks. WEP uses RC4 with 40-bit keys,
+24-bit initialization vector (IV), and CRC32 to protect against packet
+forgery. All these choices have proven to be insufficient: key space is
+too small against current attacks, RC4 key scheduling is insufficient
+(beginning of the pseudorandom stream should be skipped), IV space is
+too small and IV reuse makes attacks easier, there is no replay
+protection, and non-keyed authentication does not protect against bit
+flipping packet data.
+
+WPA is an intermediate solution for the security issues. It uses
+Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
+compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+
+Keys can be managed using two different mechanisms. WPA can either use
+an external authentication server (e.g., RADIUS) and EAP just like
+IEEE 802.1X is using or pre-shared keys without need for additional
+servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
+respectively. Both mechanisms will generate a master session key for
+the Authenticator (AP) and Supplicant (client station).
+
+WPA implements a new key handshake (4-Way Handshake and Group Key
+Handshake) for generating and exchanging data encryption keys between
+the Authenticator and Supplicant. This handshake is also used to
+verify that both Authenticator and Supplicant know the master session
+key. These handshakes are identical regardless of the selected key
+management mechanism (only the method for generating master session
+key changes).
+
+
+
+IEEE 802.11i / WPA2
+-------------------
+
+The design for parts of IEEE 802.11i that were not included in WPA has
+finished (May 2004) and this amendment to IEEE 802.11 was approved in
+June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
+version of WPA called WPA2. This includes, e.g., support for more
+robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
+to replace TKIP and optimizations for handoff (reduced number of
+messages in initial key handshake, pre-authentication, and PMKSA caching).
+
+
+
+wpa_supplicant
+--------------
+
+wpa_supplicant is an implementation of the WPA Supplicant component,
+i.e., the part that runs in the client stations. It implements WPA key
+negotiation with a WPA Authenticator and EAP authentication with
+Authentication Server. In addition, it controls the roaming and IEEE
+802.11 authentication/association of the wlan driver.
+
+wpa_supplicant is designed to be a "daemon" program that runs in the
+background and acts as the backend component controlling the wireless
+connection. wpa_supplicant supports separate frontend programs and an
+example text-based frontend, wpa_cli, is included with wpa_supplicant.
+
+Following steps are used when associating with an AP using WPA:
+
+- wpa_supplicant requests the kernel driver to scan neighboring BSSes
+- wpa_supplicant selects a BSS based on its configuration
+- wpa_supplicant requests the kernel driver to associate with the chosen
+ BSS
+- If WPA-EAP: integrated IEEE 802.1X Supplicant completes EAP
+ authentication with the authentication server (proxied by the
+ Authenticator in the AP)
+- If WPA-EAP: master key is received from the IEEE 802.1X Supplicant
+- If WPA-PSK: wpa_supplicant uses PSK as the master session key
+- wpa_supplicant completes WPA 4-Way Handshake and Group Key Handshake
+ with the Authenticator (AP)
+- wpa_supplicant configures encryption keys for unicast and broadcast
+- normal data packets can be transmitted and received
+
+
+
+Building and installing
+-----------------------
+
+In order to be able to build wpa_supplicant, you will first need to
+select which parts of it will be included. This is done by creating a
+build time configuration file, .config, in the wpa_supplicant root
+directory. Configuration options are text lines using following
+format: CONFIG_<option>=y. Lines starting with # are considered
+comments and are ignored. See defconfig file for an example configuration
+and a list of available options and additional notes.
+
+The build time configuration can be used to select only the needed
+features and limit the binary size and requirements for external
+libraries. The main configuration parts are the selection of which
+driver interfaces (e.g., hostap, madwifi, ..) and which authentication
+methods (e.g., EAP-TLS, EAP-PEAP, ..) are included.
+
+Following build time configuration options are used to control IEEE
+802.1X/EAPOL and EAP state machines and all EAP methods. Including
+TLS, PEAP, or TTLS will require linking wpa_supplicant with OpenSSL
+library for TLS implementation. Alternatively, GnuTLS or the internal
+TLSv1 implementation can be used for TLS functionaly.
+
+CONFIG_IEEE8021X_EAPOL=y
+CONFIG_EAP_MD5=y

+CONFIG_EAP_PAX=y
+CONFIG_EAP_LEAP=y
+
+Following option can be used to include GSM SIM/USIM interface for GSM/UMTS
+authentication algorithm (for EAP-SIM/EAP-AKA). This requires pcsc-lite
+(http://www.linuxnet.com/) for smart card access.
+
+CONFIG_PCSC=y
+
+Following options can be added to .config to select which driver
+interfaces are included. Hermes driver interface needs to be downloaded
+from Agere (see above). CONFIG_WIRELESS_EXTENSION will be used
+automatically if any of the selected drivers need it.
+
+CONFIG_WIRELESS_EXTENSION=y
+CONFIG_DRIVER_HOSTAP=y

+CONFIG_DRIVER_HERMES=y
+CONFIG_DRIVER_MADWIFI=y
+CONFIG_DRIVER_ATMEL=y

+CONFIG_EAP_LEAP=y
+CONFIG_PCSC=y
+
+EAP-PEAP and EAP-TTLS will automatically include configured EAP
+methods (MD5, OTP, GTC, MSCHAPV2) for inner authentication selection.
+
+
+After you have created a configuration file, you can build
+wpa_supplicant and wpa_cli with 'make' command. You may then install
+the binaries to a suitable system directory, e.g., /usr/local/bin.
+
+Example commands:
+
+# build wpa_supplicant and wpa_cli
+make
+# install binaries (this may need root privileges)
+cp wpa_cli wpa_supplicant /usr/local/bin
+
+
+You will need to make a configuration file, e.g.,
+/etc/wpa_supplicant.conf, with network configuration for the networks
+you are going to use. Configuration file section below includes
+explanation fo the configuration file format and includes various
+examples. Once the configuration is ready, you can test whether the
+configuration work by first running wpa_supplicant with following
+command to start it on foreground with debugging enabled:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d
+
+Assuming everything goes fine, you can start using following command
+to start wpa_supplicant on background without debugging:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
+
+Please note that if you included more than one driver interface in the
+build time configuration (.config), you may need to specify which
+interface to use by including -D<driver name> option on the command
+line. See following section for more details on command line options
+for wpa_supplicant.
+
+
+
+Command line options
+--------------------
+
+usage:
+ wpa_supplicant [-BddfhKLqqtuvwW] [-P<pid file>] [-g<global ctrl>] \
+ -i<ifname> -c<config file> [-C<ctrl>] [-D<driver>] [-p<driver_param>] \
+ [-b<br_ifname> [-N -i<ifname> -c<conf> [-C<ctrl>] [-D<driver>] \
+ [-p<driver_param>] [-b<br_ifname>] ...]
+
+options:
+ -b = optional bridge interface name
+ -B = run daemon in the background
+ -c = Configuration file
+ -C = ctrl_interface parameter (only used if -c is not)
+ -i = interface name
+ -d = increase debugging verbosity (-dd even more)
+ -D = driver name
+ -f = Log output to default log location (normally /tmp)
+ -g = global ctrl_interface
+ -K = include keys (passwords, etc.) in debug output
+ -t = include timestamp in debug messages
+ -h = show this help text
+ -L = show license (GPL and BSD)
+ -p = driver parameters
+ -P = PID file
+ -q = decrease debugging verbosity (-qq even less)
+ -v = show version
+ -w = wait for interface to be added, if needed
+ -W = wait for a control interface monitor before starting
+ -N = start describing new interface
+
+drivers:
+ hostap = Host AP driver (Intersil Prism2/2.5/3) [default]
+ (this can also be used with Linuxant DriverLoader)
+ hermes = Agere Systems Inc. driver (Hermes-I/Hermes-II)
+ madwifi = MADWIFI 802.11 support (Atheros, etc.)
+ atmel = ATMEL AT76C5XXx (USB, PCMCIA)
+ wext = Linux wireless extensions (generic)
+ ndiswrapper = Linux ndiswrapper
+ broadcom = Broadcom wl.o driver
+ ipw = Intel ipw2100/2200 driver (old; use wext with Linux 2.6.13 or newer)
+ wired = wpa_supplicant wired Ethernet driver
+ bsd = BSD 802.11 support (Atheros, etc.)
+ ndis = Windows NDIS driver
+
+In most common cases, wpa_supplicant is started with
+
+wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -iwlan0
+
+This makes the process fork into background and wait for the wlan0
+interface if it is not available at startup time.
+
+The easiest way to debug problems, and to get debug log for bug
+reports, is to start wpa_supplicant on foreground with debugging
+enabled:
+
+wpa_supplicant -c/etc/wpa_supplicant.conf -iwlan0 -d
+
+
+wpa_supplicant can control multiple interfaces (radios) either by
+running one process for each interface separately or by running just
+one process and list of options at command line. Each interface is
+separated with -N argument. As an example, following command would
+start wpa_supplicant for two interfaces:
+
+wpa_supplicant \
+ -c wpa1.conf -i wlan0 -D hostap -N \
+ -c wpa2.conf -i ath0 -D madwifi
+
+
+If the interface is added in a Linux bridge (e.g., br0), the bridge
+interface needs to be configured to wpa_supplicant in addition to the
+main interface:
+
+wpa_supplicant -cw.conf -Dmadwifi -iath0 -bbr0
+
+
+Configuration file
+------------------
+
+wpa_supplicant is configured using a text file that lists all accepted
+networks and security policies, including pre-shared keys. See
+example configuration file, wpa_supplicant.conf, for detailed
+information about the configuration format and supported fields.
+
+Changes to configuration file can be reloaded be sending SIGHUP signal
+to wpa_supplicant ('killall -HUP wpa_supplicant'). Similarly,
+reloading can be triggered with 'wpa_cli reconfigure' command.
+
+Configuration file can include one or more network blocks, e.g., one
+for each used SSID. wpa_supplicant will automatically select the best
+betwork based on the order of network blocks in the configuration
+file, network security level (WPA/WPA2 is preferred), and signal
+strength.
+
+Example configuration files for some common configurations:
+
+1) WPA-Personal (PSK) as home network and WPA-Enterprise with EAP-TLS as work
+ network
+
+# allow frontend (e.g., wpa_cli) to be used by all users in 'wheel' group
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+#
+# home network; allow all valid ciphers
+network={
+ ssid="home"
+ scan_ssid=1
+ key_mgmt=WPA-PSK
+ psk="very secret passphrase"
+}
+#
+# work network; use EAP-TLS with WPA; allow only CCMP and TKIP ciphers
+network={
+ ssid="work"
+ scan_ssid=1
+ key_mgmt=WPA-EAP
+ pairwise=CCMP TKIP
+ group=CCMP TKIP
+ eap=TLS
+ identity="user@example.com"
+ ca_cert="/etc/cert/ca.pem"
+ client_cert="/etc/cert/user.pem"
+ private_key="/etc/cert/user.prv"
+ private_key_passwd="password"
+}
+
+
+2) WPA-RADIUS/EAP-PEAP/MSCHAPv2 with RADIUS servers that use old peaplabel
+ (e.g., Funk Odyssey and SBR, Meetinghouse Aegis, Interlink RAD-Series)
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+ ssid="example"
+ scan_ssid=1
+ key_mgmt=WPA-EAP
+ eap=PEAP
+ identity="user@example.com"
+ password="foobar"
+ ca_cert="/etc/cert/ca.pem"
+ phase1="peaplabel=0"
+ phase2="auth=MSCHAPV2"
+}
+
+
+3) EAP-TTLS/EAP-MD5-Challenge configuration with anonymous identity for the
+ unencrypted use. Real identity is sent only within an encrypted TLS tunnel.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+ ssid="example"
+ scan_ssid=1
+ key_mgmt=WPA-EAP
+ eap=TTLS
+ identity="user@example.com"
+ anonymous_identity="anonymous@example.com"
+ password="foobar"
+ ca_cert="/etc/cert/ca.pem"
+ phase2="auth=MD5"
+}
+
+
+4) IEEE 802.1X (i.e., no WPA) with dynamic WEP keys (require both unicast and
+ broadcast); use EAP-TLS for authentication
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+ ssid="1x-test"
+ scan_ssid=1
+ key_mgmt=IEEE8021X
+ eap=TLS
+ identity="user@example.com"
+ ca_cert="/etc/cert/ca.pem"
+ client_cert="/etc/cert/user.pem"
+ private_key="/etc/cert/user.prv"
+ private_key_passwd="password"
+ eapol_flags=3
+}
+
+
+5) Catch all example that allows more or less all configuration modes. The
+ configuration options are used based on what security policy is used in the
+ selected SSID. This is mostly for testing and is not recommended for normal
+ use.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+ ssid="example"
+ scan_ssid=1
+ key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
+ pairwise=CCMP TKIP
+ group=CCMP TKIP WEP104 WEP40
+ psk="very secret passphrase"
+ eap=TTLS PEAP TLS
+ identity="user@example.com"
+ password="foobar"
+ ca_cert="/etc/cert/ca.pem"
+ client_cert="/etc/cert/user.pem"
+ private_key="/etc/cert/user.prv"
+ private_key_passwd="password"
+ phase1="peaplabel=0"
+ ca_cert2="/etc/cert/ca2.pem"
+ client_cert2="/etc/cer/user.pem"
+ private_key2="/etc/cer/user.prv"
+ private_key2_passwd="password"
+}
+
+
+6) Authentication for wired Ethernet. This can be used with 'wired' interface
+ (-Dwired on command line).
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+ap_scan=0
+network={
+ key_mgmt=IEEE8021X
+ eap=MD5
+ identity="user"
+ password="password"
+ eapol_flags=0
+}
+
+
+
+Certificates
+------------
+
+Some EAP authentication methods require use of certificates. EAP-TLS
+uses both server side and client certificates whereas EAP-PEAP and
+EAP-TTLS only require the server side certificate. When client
+certificate is used, a matching private key file has to also be
+included in configuration. If the private key uses a passphrase, this
+has to be configured in wpa_supplicant.conf ("private_key_passwd").
+
+wpa_supplicant supports X.509 certificates in PEM and DER
+formats. User certificate and private key can be included in the same
+file.
+
+If the user certificate and private key is received in PKCS#12/PFX
+format, they need to be converted to suitable PEM/DER format for
+wpa_supplicant. This can be done, e.g., with following commands:
+
+# convert client certificate and private key to PEM format
+openssl pkcs12 -in example.pfx -out user.pem -clcerts
+# convert CA certificate (if included in PFX file) to PEM format
+openssl pkcs12 -in example.pfx -out ca.pem -cacerts -nokeys
+
+
+
+wpa_cli
+-------
+
+wpa_cli is a text-based frontend program for interacting with
+wpa_supplicant. It is used to query current status, change
+configuration, trigger events, and request interactive user input.
+
+wpa_cli can show the current authentication status, selected security
+mode, dot11 and dot1x MIBs, etc. In addition, it can configure some
+variables like EAPOL state machine parameters and trigger events like
+reassociation and IEEE 802.1X logoff/logon. wpa_cli provides a user
+interface to request authentication information, like username and
+password, if these are not included in the configuration. This can be
+used to implement, e.g., one-time-passwords or generic token card
+authentication where the authentication is based on a
+challenge-response that uses an external device for generating the
+response.
+
+The control interface of wpa_supplicant can be configured to allow
+non-root user access (ctrl_interface_group in the configuration
+file). This makes it possible to run wpa_cli with a normal user
+account.
+
+wpa_cli supports two modes: interactive and command line. Both modes
+share the same command set and the main difference is in interactive
+mode providing access to unsolicited messages (event messages,
+username/password requests).
+
+Interactive mode is started when wpa_cli is executed without including
+the command as a command line parameter. Commands are then entered on
+the wpa_cli prompt. In command line mode, the same commands are
+entered as command line arguments for wpa_cli.
+
+
+Interactive authentication parameters request
+
+When wpa_supplicant need authentication parameters, like username and
+password, which are not present in the configuration file, it sends a
+request message to all attached frontend programs, e.g., wpa_cli in
+interactive mode. wpa_cli shows these requests with
+"CTRL-REQ-<type>-<id>:<text>" prefix. <type> is IDENTITY, PASSWORD, or
+OTP (one-time-password). <id> is a unique identifier for the current
+network. <text> is description of the request. In case of OTP request,
+it includes the challenge from the authentication server.
+
+The reply to these requests can be given with 'identity', 'password',
+and 'otp' commands. <id> needs to be copied from the the matching
+request. 'password' and 'otp' commands can be used regardless of
+whether the request was for PASSWORD or OTP. The main difference
+between these two commands is that values given with 'password' are
+remembered as long as wpa_supplicant is running whereas values given
+with 'otp' are used only once and then forgotten, i.e., wpa_supplicant
+will ask frontend for a new value for every use. This can be used to
+implement one-time-password lists and generic token card -based
+authentication.
+
+Example request for password and a matching reply:
+
+CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
+> password 1 mysecretpassword
+
+Example request for generic token card challenge-response:
+
+CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
+> otp 2 9876

+
+
+Using wpa_cli to run external program on connect/disconnect
+-----------------------------------------------------------
+
+wpa_cli can used to run external programs whenever wpa_supplicant
+connects or disconnects from a network. This can be used, e.g., to
+update network configuration and/or trigget DHCP client to update IP
+addresses, etc.
+
+One wpa_cli process in "action" mode needs to be started for each
+interface. For example, the following command starts wpa_cli for the
+default ingterface (-i can be used to select the interface in case of
+more than one interface being used at the same time):
+
+wpa_cli -a/sbin/wpa_action.sh -B
+
+The action file (-a option, /sbin/wpa_action.sh in this example) will
+be executed whenever wpa_supplicant completes authentication (connect
+event) or detects disconnection). The action script will be called
+with two command line arguments: interface name and event (CONNECTED
+or DISCONNECTED). If the action script needs to get more information
+about the current network, it can use 'wpa_cli status' to query
+wpa_supplicant for more information.
+
+Following example can be used as a simple template for an action
+script:
+
+#!/bin/sh
+
+IFNAME=$1
+CMD=$2
+
+if [ "$CMD" == "CONNECTED" ]; then
+ SSID=`wpa_cli -i$IFNAME status | grep ^ssid= | cut -f2- -d=`
+ # configure network, signal DHCP client, etc.
+fi
+
+if [ "$CMD" == "DISCONNECTED" ]; then
+ # remove network configuration, if needed
+fi
+
+
+
+Integrating with pcmcia-cs/cardmgr scripts
+------------------------------------------
+
+wpa_supplicant needs to be running when using a wireless network with
+WPA. It can be started either from system startup scripts or from
+pcmcia-cs/cardmgr scripts (when using PC Cards). WPA handshake must be
+completed before data frames can be exchanged, so wpa_supplicant
+should be started before DHCP client.
+
+Command line option '-w' can be used if wpa_supplicant is started
+before the wireless LAN interface is present (e.g., before inserting
+the PC Card) or is not yet up.
+
+For example, following small changes to pcmcia-cs scripts can be used
+to enable WPA support:
+
+Add MODE="Managed" and WPA="y" to the network scheme in
+/etc/pcmcia/wireless.opts.
+
+Add the following block to the end of 'start' action handler in
+/etc/pcmcia/wireless:
+
+ if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+ /usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf \
+ -i$DEVICE
+ fi
+
+Add the following block to the end of 'stop' action handler (may need
+to be separated from other actions) in /etc/pcmcia/wireless:
+
+ if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+ killall wpa_supplicant
+ fi
+
+This will make cardmgr start wpa_supplicant when the card is plugged
+in. wpa_supplicant will wait until the interface is set up--either
+when a static IP address is configured or when DHCP client is
+started--and will then negotiate keys with the AP.
+
+
+
+Dynamic interface add and operation without configuration files
+---------------------------------------------------------------
+
+wpa_supplicant can be started without any configuration files or
+network interfaces. When used in this way, a global (i.e., per
+wpa_supplicant process) control interface is used to add and remove
+network interfaces. Each network interface can then be configured
+through a per-network interface control interface. For example,
+following commands show how to start wpa_supplicant without any
+network interfaces and then add a network interface and configure a
+network (SSID):
+
+# Start wpa_supplicant in the background
+wpa_supplicant -g/var/run/wpa_supplicant-global -B
+
+# Add a new interface (wlan0, no configuration file, driver=wext, and
+# enable control interface)
+wpa_cli -g/var/run/wpa_supplicant-global interface_add wlan0 \
+ "" wext /var/run/wpa_supplicant
+
+# Configure a network using the newly added network interface:
+wpa_cli -iwlan0 add_network
+wpa_cli -iwlan0 set_network 0 ssid '"test"'
+wpa_cli -iwlan0 set_network 0 key_mgmt WPA-PSK
+wpa_cli -iwlan0 set_network 0 psk '"12345678"'
+wpa_cli -iwlan0 set_network 0 pairwise TKIP
+wpa_cli -iwlan0 set_network 0 group TKIP
+wpa_cli -iwlan0 set_network 0 proto WPA
+wpa_cli -iwlan0 enable_network 0
+
+# At this point, the new network interface should start trying to associate
+# with the WPA-PSK network using SSID test.
+
+# Remove network interface
+wpa_cli -g/var/run/wpa_supplicant-global interface_remove wlan0

+
+
+wpa_supplicant has support for being used as a WPA/WPA2/IEEE 802.1X
+Supplicant on Windows. The current port requires that WinPcap
+(http://winpcap.polito.it/) is installed for accessing packets and the
+driver interface. Both release versions 3.0 and 3.1 are supported.
+
+The current port is still somewhat experimental. It has been tested
+mainly on Windows XP (SP2) with limited set of NDIS drivers. In
+addition, the current version has been reported to work with Windows
+2000.
+
+All security modes have been verified to work (at least complete
+authentication and successfully ping a wired host):

+
+
+Binary version
+--------------
+
+Compiled binary version of the wpa_supplicant and additional tools is
+available from http://hostap.epitest.fi/wpa_supplicant/. These
+binaries can be used after installing WinPcap.
+
+
+Building wpa_supplicant with mingw
+----------------------------------
+
+The default build setup for wpa_supplicant is to use MinGW and
+cross-compiling from Linux to MinGW/Windows. It should also be
+possible to build this under Windows using the MinGW tools, but that
+is not tested nor supported and is likely to require some changes to
+the Makefile unless cygwin is used.
+
+
+Building wpa_supplicant with MSVC
+---------------------------------
+
+wpa_supplicant can be built with Microsoft Visual C++ compiler. This
+has been tested with Microsoft Visual C++ Toolkit 2003 and Visual
+Studio 2005 using the included nmake.mak as a Makefile for nmake. IDE
+can also be used by creating a project that includes the files and
+defines mentioned in nmake.mak. Example VS2005 solution and project
+files are included in vs2005 subdirectory. This can be used as a
+starting point for building the programs with VS2005 IDE.
+
+WinPcap development package is needed for the build and this can be
+downloaded from http://www.winpcap.org/install/bin/WpdPack_3_1.zip. The
+default nmake.mak expects this to be unpacked into C:\dev\WpdPack so
+that Include and Lib directories are in this directory. The files can be
+stored elsewhere as long as the WINPCAPDIR in nmake.mak is updated to
+match with the selected directory. In case a project file in the IDE is
+used, these Include and Lib directories need to be added to project
+properties as additional include/library directories.
+
+OpenSSL source package can be downloaded from
+http://www.openssl.org/source/openssl-0.9.8b.tar.gz and built and
+installed following instructions in INSTALL.W32. Note that if EAP-FAST
+support will be included in the wpa_supplicant, OpenSSL needs to be
+patched to# support it openssl-tls-extensions.patch. The example
+nmake.mak file expects OpenSSL to be installed into C:\dev\openssl, but
+this directory can be modified by changing OPENSSLDIR variable in
+nmake.mak.
+
+If you do not need EAP-FAST support, you may also be able to use Win32
+binary installation package of OpenSSL from
+http://www.slproweb.com/products/Win32OpenSSL.html instead of building
+the library yourself. In this case, you will need to copy Include and
+Lib directories in suitable directory, e.g., C:\dev\openssl for the
+default nmake.mak. Copy {Win32OpenSSLRoot}\include into
+C:\dev\openssl\include and make C:\dev\openssl\lib subdirectory with
+files from {Win32OpenSSLRoot}\VC (i.e., libeay*.lib and ssleay*.lib).
+This will end up using dynamically linked OpenSSL (i.e., .dll files are
+needed) for it. Alternative, you can copy files from
+{Win32OpenSSLRoot}\VC\static to create a static build (no OpenSSL .dll
+files needed).
+
+
+Building wpa_supplicant for cygwin
+----------------------------------
+
+wpa_supplicant can be built for cygwin by installing the needed
+development packages for cygwin. This includes things like compiler,
+make, openssl development package, etc. In addition, developer's pack
+for WinPcap (WPdpack.zip) from
+http://winpcap.polito.it/install/default.htm is needed.
+
+.config file should enable only one driver interface,
+CONFIG_DRIVER_NDIS. In addition, include directories may need to be
+added to match the system. An example configuration is available in
+defconfig. The library and include files for WinPcap will either need
+to be installed in compiler/linker default directories or their
+location will need to be adding to .config when building
+wpa_supplicant.
+
+Othen than this, the build should be more or less identical to Linux
+version, i.e., just run make after having created .config file. An
+additional tool, win_if_list.exe, can be built by running "make
+win_if_list".
+
+
+Building wpa_gui
+----------------
+
+wpa_gui uses Qt application framework from Trolltech. It can be built
+with the open source version of Qt4 and MinGW. Following commands can
+be used to build the binary in the Qt 4 Command Prompt:
+
+# go to the root directory of wpa_supplicant source code
+cd wpa_gui-qt4
+qmake -o Makefile wpa_gui.pro
+make
+# the wpa_gui.exe binary is created into 'release' subdirectory
+
+
+Using wpa_supplicant for Windows
+--------------------------------
+
+wpa_supplicant and wpa_cli behave more or less identically to Linux
+version, so instructions in README and example wpa_supplicant.conf
+should be applicable for most parts. In addition, there is another
+version of wpa_supplicant, wpasvc.exe, which can be used as a Windows
+service and which reads its configuration from registry instead of
+text file.
+
+When using access points in "hidden SSID" mode, ap_scan=2 mode need to
+be used (see wpa_supplicant.conf for more information).
+
+Windows NDIS/WinPcap uses quite long interface names, so some care
+will be needed when starting wpa_supplicant. Alternatively, the
+adapter description can be used as the interface name which may be
+easier since it is usually in more human-readable
+format. win_if_list.exe can be used to find out the proper interface
+name.
+
+Example steps in starting up wpa_supplicant:
+
+# win_if_list.exe
+ifname: \Device\NPF_GenericNdisWanAdapter
+description: Generic NdisWan adapter
+
+ifname: \Device\NPF_{769E012B-FD17-4935-A5E3-8090C38E25D2}
+description: Atheros Wireless Network Adapter (Microsoft's Packet Scheduler)
+
+ifname: \Device\NPF_{732546E7-E26C-48E3-9871-7537B020A211}
+description: Intel 8255x-based Integrated Fast Ethernet (Microsoft's Packet Scheduler)
+
+
+Since the example configuration used Atheros WLAN card, the middle one
+is the correct interface in this case. The interface name for -i
+command line option is the full string following "ifname:" (the
+"\Device\NPF_" prefix can be removed). In other words, wpa_supplicant
+would be started with the following command:
+
+# wpa_supplicant.exe -i'{769E012B-FD17-4935-A5E3-8090C38E25D2}' -c wpa_supplicant.conf -d
+
+-d optional enables some more debugging (use -dd for even more, if
+needed). It can be left out if debugging information is not needed.
+
+With the alternative mechanism for selecting the interface, this
+command has identical results in this case:
+
+# wpa_supplicant.exe -iAtheros -c wpa_supplicant.conf -d
+
+
+Simple configuration example for WPA-PSK:
+
+#ap_scan=2
+ctrl_interface=
+network={
+ ssid="test"
+ key_mgmt=WPA-PSK
+ proto=WPA
+ pairwise=TKIP
+ psk="secret passphrase"
+}
+
+(remove '#' from the comment out ap_scan line to enable mode in which
+wpa_supplicant tries to associate with the SSID without doing
+scanning; this allows APs with hidden SSIDs to be used)
+
+
+wpa_cli.exe and wpa_gui.exe can be used to interact with the
+wpa_supplicant.exe program in the same way as with Linux. Note that
+ctrl_interface is using UNIX domain sockets when built for cygwin, but
+the native build for Windows uses named pipes and the contents of the
+ctrl_interface configuration item is used to control access to the
+interface. Anyway, this variable has to be included in the configuration
+to enable the control interface.
+
+
+Example SDDL string formats:
+
+(local admins group has permission, but nobody else):
+
+ctrl_interface=SDDL=D:(A;;GA;;;BA)
+
+("A" == "access allowed", "GA" == GENERIC_ALL == all permissions, and
+"BA" == "builtin administrators" == the local admins. The empty fields
+are for flags and object GUIDs, none of which should be required in this
+case.)
+
+(local admins and the local "power users" group have permissions,
+but nobody else):
+
+ctrl_interface=SDDL=D:(A;;GA;;;BA)(A;;GA;;;PU)
+
+(One ACCESS_ALLOWED ACE for GENERIC_ALL for builtin administrators, and
+one ACCESS_ALLOWED ACE for GENERIC_ALL for power users.)
+
+(close to wide open, but you have to be a valid user on
+the machine):
+
+ctrl_interface=SDDL=D:(A;;GA;;;AU)
+
+(One ACCESS_ALLOWED ACE for GENERIC_ALL for the "authenticated users"
+group.)
+
+This one would allow absolutely everyone (including anonymous
+users) -- this is *not* recommended, since named pipes can be attached
+to from anywhere on the network (i.e. there's no "this machine only"
+like there is with 127.0.0.1 sockets):
+
+ctrl_interface=SDDL=D:(A;;GA;;;BU)(A;;GA;;;AN)
+
+(BU == "builtin users", "AN" == "anonymous")
+
+See also [1] for the format of ACEs, and [2] for the possible strings
+that can be used for principal names.

+
+
+Starting wpa_supplicant as a Windows service (wpasvc.exe)
+---------------------------------------------------------
+
+wpa_supplicant can be started as a Windows service by using wpasvc.exe
+program that is alternative build of wpa_supplicant.exe. Most of the
+core functionality of wpasvc.exe is identical to wpa_supplicant.exe,
+but it is using Windows registry for configuration information instead
+of a text file and command line parameters. In addition, it can be
+registered as a service that can be started automatically or manually
+like any other Windows service.
+
+The root of wpa_supplicant configuration in registry is
+HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant. This level includes global
+parameters and a 'interfaces' subkey with all the interface configuration
+(adapter to confname mapping). Each such mapping is a subkey that has
+'adapter', 'config', and 'ctrl_interface' values.
+
+This program can be run either as a normal command line application,
+e.g., for debugging, with 'wpasvc.exe app' or as a Windows service.
+Service need to be registered with 'wpasvc.exe reg <full path to
+wpasvc.exe>'. Alternatively, 'wpasvc.exe reg' can be used to register
+the service with the current location of wpasvc.exe. After this, wpasvc
+can be started like any other Windows service (e.g., 'net start wpasvc')
+or it can be configured to start automatically through the Services tool
+in administrative tasks. The service can be unregistered with
+'wpasvc.exe unreg'.
+
+If the service is set to start during system bootup to make the
+network connection available before any user has logged in, there may
+be a long (half a minute or so) delay in starting up wpa_supplicant
+due to WinPcap needing a driver called "Network Monitor Driver" which
+is started by default on demand.
+
+To speed up wpa_supplicant start during system bootup, "Network
+Monitor Driver" can be configured to be started sooner by setting its
+startup type to System instead of the default Demand. To do this, open
+up Device Manager, select Show Hidden Devices, expand the "Non
+Plug-and-Play devices" branch, double click "Network Monitor Driver",
+go to the Driver tab, and change the Demand setting to System instead.
+
+Configuration data is in HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant\configs
+key. Each configuration profile has its own key under this. In terms of text
+files, each profile would map to a separate text file with possibly multiple
+networks. Under each profile, there is a networks key that lists all
+networks as a subkey. Each network has set of values in the same way as
+network block in the configuration file. In addition, blobs subkey has
+possible blobs as values.
+
+HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant\configs\test\networks\0000
+ ssid="example"
+ key_mgmt=WPA-PSK
+
+See win_example.reg for an example on how to setup wpasvc.exe
+parameters in registry. It can also be imported to registry as a
+starting point for the configuration.

+ * offset to the field containing the length of the configuration variable.
+ * .param3 and .param4 can be used to mark the allowed range (length for STR
+ * and value for INT).
+ *
+ * For each configuration line in wpa_supplicant.conf, the parser goes through
+ * this table and select the entry that matches with the field name. The parser
+ * function (.parser) is then called to parse the actual value of the field.
+ *
+ * This kind of mechanism makes it easy to add new configuration parameters,
+ * since only one line needs to be added into this table and into the

+ * The meaning of this string depends on which control interface
+ * mechanism is used. For all cases, the existance of this parameter
+ * in configuration is used to determine whether the control interface
+ * is enabled.
+ *
+ * For UNIX domain sockets (default on Linux and BSD): This is a
+ * directory that will be created for UNIX domain sockets for listening
+ * to requests from external programs (CLI/GUI, etc.) for status
+ * information and configuration. The socket file will be named based
+ * on the interface name, so multiple %wpa_supplicant processes can be
+ * run at the same time if more than one interface is used.
+ * /var/run/wpa_supplicant is the recommended directory for sockets and
+ * by default, wpa_cli will use it when trying to connect with
+ * %wpa_supplicant.
+ *
+ * Access control for the control interface can be configured
+ * by setting the directory to allow only members of a group
+ * to use sockets. This way, it is possible to run
+ * %wpa_supplicant as root (since it needs to change network
+ * configuration and open raw sockets) and still allow GUI/CLI
+ * components to be run as non-root users. However, since the
+ * control interface can be used to change the network
+ * configuration, this access needs to be protected in many
+ * cases. By default, %wpa_supplicant is configured to use gid
+ * 0 (root). If you want to allow non-root users to use the
+ * control interface, add a new group and change this value to
+ * match with that group. Add users that should have control
+ * interface access to this group.
+ *
+ * When configuring both the directory and group, use following format:
+ * DIR=/var/run/wpa_supplicant GROUP=wheel
+ * DIR=/var/run/wpa_supplicant GROUP=0
+ * (group can be either group name or gid)
+ *
+ * For UDP connections (default on Windows): The value will be ignored.
+ * This variable is just used to select that the control interface is
+ * to be created. The value can be set to, e.g., udp
+ * (ctrl_interface=udp).
+ *
+ * For Windows Named Pipe: This value can be used to set the security
+ * descriptor for controlling access to the control interface. Security
+ * descriptor can be set using Security Descriptor String Format (see
+ * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).

+
+%wpa_supplicant implementation is divided into number of independent
+modules. Core code includes functionality for controlling the network
+selection, association, and configuration. Independent modules include
+WPA code (key handshake, PMKSA caching, pre-authentication), EAPOL
+state machine, and EAP state machine and methods. In addition, there
+are number of separate files for generic helper functions.
+
+Both WPA and EAPOL/EAP state machines can be used separately in other
+programs than %wpa_supplicant. As an example, the included test
+programs eapol_test and preauth_test are using these modules.
+
+\ref driver_wrapper "Driver interface API" is defined in driver.h and
+all hardware/driver dependent functionality is implemented in
+driver_*.c.
+
+
+\section wpa_supplicant_core wpa_supplicant core functionality
+
+wpa_supplicant.c
+ Program initialization, main control loop
+
+main.c
+ main() for UNIX-like operating systems and MinGW (Windows); this
+ uses command line arguments to configure wpa_supplicant
+
+events.c
+ Driver event processing; wpa_supplicant_event() and related functions
+
+wpa_supplicant_i.h
+ Internal definitions for %wpa_supplicant core; should not be
+ included into independent modules
+
+wpa_supplicant.h
+ Definitions for driver event data and message logging
+
+
+\section generic_helper_func Generic helper functions
+
+%wpa_supplicant uses generic helper functions some of which are shared
+with with hostapd. The following C files are currently used:
+
+eloop.c and eloop.h
+ Event loop (select() loop with registerable timeouts, socket read
+ callbacks, and signal callbacks)
+
+common.c and common.h
+ Common helper functions
+
+defs.h
+ Definitions shared by multiple files
+
+l2_packet.h, l2_packet_linux.c, and l2_packet_pcap.c
+ Layer 2 (link) access wrapper (includes native Linux implementation
+ and wrappers for libdnet/libpcap). A new l2_packet implementation
+ may need to be added when porting to new operating systems that are
+ not supported by libdnet/libpcap. Makefile can be used to select which
+ l2_packet implementation is included. l2_packet_linux.c uses Linux
+ packet sockets and l2_packet_pcap.c has a more portable version using
+ libpcap and libdnet.
+
+pcsc_funcs.c and pcsc_funcs.h
+ Wrapper for PC/SC lite SIM and smart card readers
+
+priv_netlink.h
+ Private version of netlink definitions from Linux kernel header files;
+ this could be replaced with C library header file once suitable
+ version becomes commonly available
+
+version.h
+ Version number definitions
+
+wireless_copy.h
+ Private version of Linux wireless extensions definitions from kernel
+ header files; this could be replaced with C library header file once
+ suitable version becomes commonly available
+
+
+\section crypto_func Cryptographic functions
+
+md5.c and md5.h
+ MD5 (replaced with a crypto library if TLS support is included)
+ HMAC-MD5 (keyed checksum for message authenticity validation)

+
+sha1.c and sha1.h
+ SHA-1 (replaced with a crypto library if TLS support is included)
+ HMAC-SHA-1 (keyed checksum for message authenticity validation)
+ PRF-SHA-1 (pseudorandom (key/nonce generation) function)
+ PBKDF2-SHA-1 (ASCII passphrase to shared secret)
+ T-PRF (for EAP-FAST)
+ TLS-PRF (RFC 2246)
+
+aes_wrap.c, aes_wrap.h, aes.c
+ AES (replaced with a crypto library if TLS support is included),
+ AES Key Wrap Algorithm with 128-bit KEK, RFC3394 (broadcast/default
+ key encryption),
+ One-Key CBC MAC (OMAC1) hash with AES-128,
+ AES-128 CTR mode encryption,
+ AES-128 EAX mode encryption/decryption,
+ AES-128 CBC
+

+\page ctrl_iface_page Control interface
+
+%wpa_supplicant implements a control interface that can be used by
+external programs to control the operations of the %wpa_supplicant
+daemon and to get status information and event notifications. There is
+a small C library, in a form of a single C file, wpa_ctrl.c, that
+provides helper functions to facilitate the use of the control
+interface. External programs can link this file into them and then use
+the library functions documented in wpa_ctrl.h to interact with
+%wpa_supplicant. This library can also be used with C++. wpa_cli.c and
+wpa_gui are example programs using this library.
+
+There are multiple mechanisms for inter-process communication. For
+example, Linux version of %wpa_supplicant is using UNIX domain sockets
+for the control interface and Windows version UDP sockets. The use of
+the functions defined in wpa_ctrl.h can be used to hide the details of
+the used IPC from external programs.
+
+
+\section using_ctrl_iface Using the control interface
+
+External programs, e.g., a GUI or a configuration utility, that need to
+communicate with %wpa_supplicant should link in wpa_ctrl.c. This
+allows them to use helper functions to open connection to the control
+interface with wpa_ctrl_open() and to send commands with
+wpa_ctrl_request().
+
+%wpa_supplicant uses the control interface for two types of communication:
+commands and unsolicited event messages. Commands are a pair of
+messages, a request from the external program and a response from
+%wpa_supplicant. These can be executed using wpa_ctrl_request().
+Unsolicited event messages are sent by %wpa_supplicant to the control
+interface connection without specific request from the external program
+for receiving each message. However, the external program needs to
+attach to the control interface with wpa_ctrl_attach() to receive these
+unsolicited messages.
+
+If the control interface connection is used both for commands and
+unsolicited event messages, there is potential for receiving an
+unsolicited message between the command request and response.
+wpa_ctrl_request() caller will need to supply a callback, msg_cb,
+for processing these messages. Often it is easier to open two
+control interface connections by calling wpa_ctrl_open() twice and
+then use one of the connections for commands and the other one for
+unsolicited messages. This way command request/response pairs will
+not be broken by unsolicited messages. wpa_cli is an example of how
+to use only one connection for both purposes and wpa_gui demonstrates
+how to use two separate connections.
+
+Once the control interface connection is not needed anymore, it should
+be closed by calling wpa_ctrl_close(). If the connection was used for
+unsolicited event messages, it should be first detached by calling
+wpa_ctrl_detach().
+
+
+\section ctrl_iface_cmds Control interface commands
+
+Following commands can be used with wpa_ctrl_request():
+
+\subsection ctrl_iface_PING PING
+
+This command can be used to test whether %wpa_supplicant is replying
+to the control interface commands. The expected reply is \c PONG if the
+connection is open and %wpa_supplicant is processing commands.
+
+

+.SH NAME
+wpa_background \- Background information on Wi-Fi Protected Access and IEEE 802.11i
+.SH "WPA"
+.PP
+The original security mechanism of IEEE 802.11 standard was
+not designed to be strong and has proven to be insufficient for
+most networks that require some kind of security. Task group I
+(Security) of IEEE 802.11 working group
+(http://www.ieee802.org/11/) has worked to address the flaws of
+the base standard and has in practice completed its work in May
+2004. The IEEE 802.11i amendment to the IEEE 802.11 standard was
+approved in June 2004 and published in July 2004.
+.PP
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version
+of the IEEE 802.11i work (draft 3.0) to define a subset of the
+security enhancements that can be implemented with existing wlan
+hardware. This is called Wi-Fi Protected Access<TM> (WPA). This
+has now become a mandatory component of interoperability testing
+and certification done by Wi-Fi Alliance. Wi-Fi provides
+information about WPA at its web site
+(http://www.wi-fi.org/OpenSection/protected_access.asp).
+.PP
+IEEE 802.11 standard defined wired equivalent privacy (WEP)
+algorithm for protecting wireless networks. WEP uses RC4 with
+40-bit keys, 24-bit initialization vector (IV), and CRC32 to
+protect against packet forgery. All these choices have proven to
+be insufficient: key space is too small against current attacks,
+RC4 key scheduling is insufficient (beginning of the pseudorandom
+stream should be skipped), IV space is too small and IV reuse
+makes attacks easier, there is no replay protection, and non-keyed
+authentication does not protect against bit flipping packet
+data.
+.PP
+WPA is an intermediate solution for the security issues. It
+uses Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP
+is a compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+.PP
+Keys can be managed using two different mechanisms. WPA can
+either use an external authentication server (e.g., RADIUS) and
+EAP just like IEEE 802.1X is using or pre-shared keys without need
+for additional servers. Wi-Fi calls these "WPA-Enterprise" and
+"WPA-Personal", respectively. Both mechanisms will generate a
+master session key for the Authenticator (AP) and Supplicant
+(client station).
+.PP
+WPA implements a new key handshake (4-Way Handshake and
+Group Key Handshake) for generating and exchanging data encryption
+keys between the Authenticator and Supplicant. This handshake is
+also used to verify that both Authenticator and Supplicant know
+the master session key. These handshakes are identical regardless
+of the selected key management mechanism (only the method for
+generating master session key changes).
+.SH "IEEE 802.11I / WPA2"
+.PP
+The design for parts of IEEE 802.11i that were not included
+in WPA has finished (May 2004) and this amendment to IEEE 802.11
+was approved in June 2004. Wi-Fi Alliance is using the final IEEE
+802.11i as a new version of WPA called WPA2. This includes, e.g.,
+support for more robust encryption algorithm (CCMP: AES in Counter
+mode with CBC-MAC) to replace TKIP and optimizations for handoff
+(reduced number of messages in initial key handshake,
+pre-authentication, and PMKSA caching).

+.SH NAME
+wpa_cli \- WPA command line client
+.SH SYNOPSIS
+
+\fBwpa_cli\fR [ \fB-p \fIpath to ctrl sockets\fB\fR ] [ \fB-i \fIifname\fB\fR ] [ \fB-hvB\fR ] [ \fB-a \fIaction file\fB\fR ] [ \fB-P \fIpid file\fB\fR ] [ \fB\fIcommand ...\fB\fR ]
+
+.SH "OVERVIEW"
+.PP
+wpa_cli is a text-based frontend program for interacting
+with wpa_supplicant. It is used to query current status, change
+configuration, trigger events, and request interactive user
+input.
+.PP
+wpa_cli can show the current authentication status, selected
+security mode, dot11 and dot1x MIBs, etc. In addition, it can
+configure some variables like EAPOL state machine parameters and
+trigger events like reassociation and IEEE 802.1X
+logoff/logon. wpa_cli provides a user interface to request
+authentication information, like username and password, if these
+are not included in the configuration. This can be used to
+implement, e.g., one-time-passwords or generic token card
+authentication where the authentication is based on a
+challenge-response that uses an external device for generating the
+response.
+.PP
+The control interface of wpa_supplicant can be configured to
+allow non-root user access (ctrl_interface_group in the
+configuration file). This makes it possible to run wpa_cli with a
+normal user account.
+.PP
+wpa_cli supports two modes: interactive and command
+line. Both modes share the same command set and the main
+difference is in interactive mode providing access to unsolicited
+messages (event messages, username/password requests).
+.PP
+Interactive mode is started when wpa_cli is executed without
+including the command as a command line parameter. Commands are
+then entered on the wpa_cli prompt. In command line mode, the same
+commands are entered as command line arguments for wpa_cli.
+.SH "INTERACTIVE AUTHENTICATION PARAMETERS REQUEST"
+.PP
+When wpa_supplicant need authentication parameters, like
+username and password, which are not present in the configuration
+file, it sends a request message to all attached frontend programs,
+e.g., wpa_cli in interactive mode. wpa_cli shows these requests
+with "CTRL-REQ-<type>-<id>:<text>"
+prefix. <type> is IDENTITY, PASSWORD, or OTP
+(one-time-password). <id> is a unique identifier for the
+current network. <text> is description of the request. In
+case of OTP request, it includes the challenge from the
+authentication server.
+.PP
+The reply to these requests can be given with 'identity',
+'password', and 'otp' commands. <id> needs to be copied from the
+the matching request. 'password' and 'otp' commands can be used
+regardless of whether the request was for PASSWORD or OTP. The
+main difference between these two commands is that values given
+with 'password' are remembered as long as wpa_supplicant is
+running whereas values given with 'otp' are used only once and
+then forgotten, i.e., wpa_supplicant will ask frontend for a new
+value for every use. This can be used to implement
+one-time-password lists and generic token card -based
+authentication.
+.PP
+Example request for password and a matching reply:
+.sp
+.RS
+
+.nf
+CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
+> password 1 mysecretpassword
+.fi
+.RE
+.PP
+Example request for generic token card challenge-response:

+wpa_supplicant \- Wi-Fi Protected Access client and IEEE 802.1X supplicant
+.SH SYNOPSIS
+
+\fBwpa_supplicant\fR [ \fB-BddfhKLqqtuvwW\fR ] [ \fB-i\fIifname\fB\fR ] [ \fB-c\fIconfig file\fB\fR ] [ \fB-D\fIdriver\fB\fR ] [ \fB-P\fIPID_file\fB\fR ] [ \fB-f\fIoutput file\fB\fR ]
+
+.SH "OVERVIEW"
+.PP
+Wireless networks do not require physical access to the network equipment
+in the same way as wired networks. This makes it easier for unauthorized
+users to passively monitor a network and capture all transmitted frames.
+In addition, unauthorized use of the network is much easier. In many cases,
+this can happen even without user's explicit knowledge since the wireless
+LAN adapter may have been configured to automatically join any available
+network.
+.PP
+Link-layer encryption can be used to provide a layer of security for
+wireless networks. The original wireless LAN standard, IEEE 802.11,
+included a simple encryption mechanism, WEP. However, that proved to
+be flawed in many areas and network protected with WEP cannot be consider
+secure. IEEE 802.1X authentication and frequently changed dynamic WEP keys
+can be used to improve the network security, but even that has inherited
+security issues due to the use of WEP for encryption. Wi-Fi Protected
+Access and IEEE 802.11i amendment to the wireless LAN standard introduce
+a much improvement mechanism for securing wireless networks. IEEE 802.11i
+enabled networks that are using CCMP (encryption mechanism based on strong
+cryptographic algorithm AES) can finally be called secure used for
+applications which require efficient protection against unauthorized
+access.
+.PP
+\fBwpa_supplicant\fR is an implementation of
+the WPA Supplicant component, i.e., the part that runs in the
+client stations. It implements WPA key negotiation with a WPA
+Authenticator and EAP authentication with Authentication
+Server. In addition, it controls the roaming and IEEE 802.11
+authentication/association of the wireless LAN driver.
+.PP
+\fBwpa_supplicant\fR is designed to be a
+"daemon" program that runs in the background and acts as the
+backend component controlling the wireless
+connection. \fBwpa_supplicant\fR supports separate
+frontend programs and an example text-based frontend,
+\fBwpa_cli\fR, is included with
+wpa_supplicant.
+.PP
+Before wpa_supplicant can do its work, the network interface
+must be available. That means that the physical device must be
+present and enabled, and the driver for the device must have be
+loaded. Note, however, that the '-w' option of the wpa_supplicant
+daemon instructs the daemon to continue running and to wait for
+the interface to become available. Without the '-w' option, the
+daemon will exit immediately if the device is not already
+available.

+After \fBwpa_supplicant\fR has configured the

+.SH "OVERVIEW"
+.PP
+\fBwpa_supplicant\fR is configured using a text
+file that lists all accepted networks and security policies,
+including pre-shared keys. See the example configuration file,
+probably in \fB/usr/share/doc/wpa_supplicant/\fR, for
+detailed information about the configuration format and supported
+fields.
+.PP
+All file paths in this configuration file should use full
+(absolute, not relative to working directory) path in order to allow
+working directory to be changed. This can happen if wpa_supplicant is
+run in the background.
+.PP
+Changes to configuration file can be reloaded be sending
+SIGHUP signal to \fBwpa_supplicant\fR ('killall -HUP
+wpa_supplicant'). Similarly, reloading can be triggered with
+the 'wpa_cli reconfigure' command.
+.PP
+Configuration file can include one or more network blocks,
+e.g., one for each used SSID. wpa_supplicant will automatically
+select the best network based on the order of network blocks in
+the configuration file, network security level (WPA/WPA2 is

+.PP
+wpa_supplicant supports X.509 certificates in PEM and DER
+formats. User certificate and private key can be included in the
+same file.
+.PP
+If the user certificate and private key is received in

+
+ <para>
+ Wireless networks do not require physical access to the network equipment
+ in the same way as wired networks. This makes it easier for unauthorized
+ users to passively monitor a network and capture all transmitted frames.
+ In addition, unauthorized use of the network is much easier. In many cases,
+ this can happen even without user's explicit knowledge since the wireless
+ LAN adapter may have been configured to automatically join any available
+ network.
+ </para>
+
+ <para>
+ Link-layer encryption can be used to provide a layer of security for
+ wireless networks. The original wireless LAN standard, IEEE 802.11,
+ included a simple encryption mechanism, WEP. However, that proved to
+ be flawed in many areas and network protected with WEP cannot be consider
+ secure. IEEE 802.1X authentication and frequently changed dynamic WEP keys
+ can be used to improve the network security, but even that has inherited
+ security issues due to the use of WEP for encryption. Wi-Fi Protected
+ Access and IEEE 802.11i amendment to the wireless LAN standard introduce
+ a much improvement mechanism for securing wireless networks. IEEE 802.11i
+ enabled networks that are using CCMP (encryption mechanism based on strong
+ cryptographic algorithm AES) can finally be called secure used for
+ applications which require efficient protection against unauthorized
+ access.
+ </para>
+
+ <para><command>wpa_supplicant</command> is an implementation of
+ the WPA Supplicant component, i.e., the part that runs in the
+ client stations. It implements WPA key negotiation with a WPA
+ Authenticator and EAP authentication with Authentication
+ Server. In addition, it controls the roaming and IEEE 802.11
+ authentication/association of the wireless LAN driver.</para>
+
+ <para><command>wpa_supplicant</command> is designed to be a
+ "daemon" program that runs in the background and acts as the
+ backend component controlling the wireless
+ connection. <command>wpa_supplicant</command> supports separate
+ frontend programs and an example text-based frontend,
+ <command>wpa_cli</command>, is included with
+ wpa_supplicant.</para>
+
+ <para>Before wpa_supplicant can do its work, the network interface
+ must be available. That means that the physical device must be
+ present and enabled, and the driver for the device must have be
+ loaded. Note, however, that the '-w' option of the wpa_supplicant
+ daemon instructs the daemon to continue running and to wait for
+ the interface to become available. Without the '-w' option, the
+ daemon will exit immediately if the device is not already
+ available.</para>
+
+ <para>After <command>wpa_supplicant</command> has configured the
+ network device, higher level configuration such as DHCP may
+ proceed. There are a variety of ways to integrate wpa_supplicant
+ into a machine's networking scripts, a few of which are described

+ <title>Quick Start</title>
+
+ <para>First, make a configuration file, e.g.
+ <filename>/etc/wpa_supplicant.conf</filename>, that describes the networks
+ you are interested in. See <citerefentry>
+ <refentrytitle>wpa_supplicant.conf</refentrytitle>
+ <manvolnum>5</manvolnum>
+ </citerefentry>
+ for details.</para>
+
+ <para>Once the configuration is ready, you can test whether the
+ configuration works by running <command>wpa_supplicant</command>
+ with following command to start it on foreground with debugging
+ enabled:</para>
+
+ <blockquote><programlisting>
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d
+ </programlisting></blockquote>
+
+ <para>Assuming everything goes fine, you can start using following
+ command to start <command>wpa_supplicant</command> on background
+ without debugging:</para>
+
+ <blockquote><programlisting>
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
+ </programlisting></blockquote>
+
+ <para>Please note that if you included more than one driver
+ interface in the build time configuration (.config), you may need
+ to specify which interface to use by including -D<driver
+ name> option on the command line.</para>
+
+ <!-- XXX at this point, the page could include a little script
+ based on wpa_cli to wait for a connection and then run
+ dhclient -->

+ <title>Interface to pcmcia-cs/cardmrg</title>
+
+ <para>For example, following small changes to pcmcia-cs scripts
+ can be used to enable WPA support:</para>
+
+ <para>Add MODE="Managed" and WPA="y" to the network scheme in
+ <filename>/etc/pcmcia/wireless.opts</filename>.</para>
+
+ <para>Add the following block to the end of 'start' action handler

+
+ <blockquote><programlisting>
+if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+ /usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
+fi
+ </programlisting></blockquote>
+
+
+ <para>Add the following block to the end of 'stop' action handler
+ (may need to be separated from other actions) in
+ <filename>/etc/pcmcia/wireless</filename>:</para>
+
+ <blockquote><programlisting>
+if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+ killall wpa_supplicant
+fi
+ </programlisting></blockquote>
+
+ <para>This will make <command>cardmgr</command> start

+\page driver_wrapper Driver wrapper implementation (driver.h, drivers.c)
+
+All hardware and driver dependent functionality is in separate C files
+that implement defined wrapper functions. Other parts
+of the %wpa_supplicant are designed to be hardware, driver, and operating
+system independent.
+
+Driver wrappers need to implement whatever calls are used in the
+target operating system/driver for controlling wireless LAN
+devices. As an example, in case of Linux, these are mostly some glue
+code and ioctl() calls and netlink message parsing for Linux Wireless
+Extensions (WE). Since features required for WPA were added only recently to
+Linux Wireless Extensions (in version 18), some driver specific code is used
+in number of driver interface implementations. These driver dependent parts
+can be replaced with generic code in driver_wext.c once the target driver
+includes full support for WE-18. After that, all Linux drivers, at
+least in theory, could use the same driver wrapper code.
+
+A driver wrapper needs to implement some or all of the functions
+defined in driver.h. These functions are registered by filling struct
+wpa_driver_ops with function pointers. Hardware independent parts of
+%wpa_supplicant will call these functions to control the driver/wlan
+card. In addition, support for driver events is required. The event
+callback function, wpa_supplicant_event(), and its parameters are
+documented in wpa_supplicant.h. In addition, a pointer to the 'struct
+wpa_driver_ops' needs to be registered in drivers.c file.
+
+When porting to other operating systems, the driver wrapper should be
+modified to use the native interface of the target OS. It is possible
+that some extra requirements for the interface between the driver
+wrapper and generic %wpa_supplicant code are discovered during porting
+to a new operating system. These will be addressed on case by case
+basis by modifying the interface and updating the other driver
+wrappers for this. The goal is to avoid changing this interface
+without very good reasons in order to limit the number of changes
+needed to other wrappers and hardware independent parts of
+%wpa_supplicant. When changes are required, recommended way is to
+make them in backwards compatible way that allows existing driver
+interface implementations to be compiled without any modification.
+
+Generic Linux Wireless Extensions functions are implemented in
+driver_wext.c. All Linux driver wrappers can use these when the kernel
+driver supports the generic ioctl()s and wireless events. Driver
+specific functions are implemented in separate C files, e.g.,
+driver_hostap.c. These files need to define struct wpa_driver_ops
+entry that will be used in wpa_supplicant.c when calling driver
+functions. struct wpa_driver_ops entries are registered in drivers.c.
+
+In general, it is likely to be useful to first take a look at couple
+of driver interface examples before starting on implementing a new
+one. driver_hostap.c and driver_wext.c include a complete
+implementation for Linux drivers that use %wpa_supplicant-based control
+of WPA IE and roaming. driver_ndis.c (with help from driver_ndis_.c)
+is an example of a complete interface for Windows NDIS interface for
+drivers that generate WPA IE themselves and decide when to roam. These
+example implementations include full support for all security modes.
+
+
+\section driver_req Driver requirements for WPA
+
+WPA introduces new requirements for the device driver. At least some
+of these need to be implemented in order to provide enough support for
+%wpa_supplicant.
+
+\subsection driver_tkip_ccmp TKIP/CCMP
+
+WPA requires that the pairwise cipher suite (encryption algorithm for
+unicast data packets) is TKIP or CCMP. These are new encryption
+protocols and thus, the driver will need to be modified to support
+them. Depending on the used wlan hardware, some parts of these may be
+implemented by the hardware/firmware.
+
+Specification for both TKIP and CCMP is available from IEEE (IEEE
+802.11i amendment). Fully functional, hardware independent
+implementation of both encryption protocols is also available in Host
+AP driver (driver/modules/hostap_{tkip,ccmp}.c). In addition, Linux 2.6
+kernel tree has generic implementations for WEP, TKIP, and CCMP that can
+be used in Linux drivers.
+
+The driver will also need to provide configuration mechanism to allow
+user space programs to configure TKIP and CCMP. Linux Wireless Extensions
+v18 added support for configuring these algorithms and
+individual/non-default keys. If the target kernel does not include WE-18,
+private ioctls can be used to provide similar functionality.
+
+\subsection driver_roaming Roaming control and scanning support
+
+%wpa_supplicant can optionally control AP selection based on the
+information received from Beacon and/or Probe Response frames
+(ap_scan=1 mode in configuration). This means that the driver should
+support external control for scan process. In case of Linux, use of
+new Wireless Extensions scan support (i.e., 'iwlist wlan0 scan') is
+recommended. The current driver wrapper (driver_wext.c) uses this for
+scan results.
+
+Scan results must also include the WPA information element. Support for
+this was added in WE-18. With older versions, a custom event can be used
+to provide the full WPA IE (including element id and length) as a hex
+string that is included in the scan results.
+
+%wpa_supplicant needs to also be able to request the driver to
+associate with a specific BSS. Current Host AP driver and matching
+driver_hostap.c wrapper uses following sequence for this
+request. Similar/identical mechanism should be usable also with other
+drivers.
+
+- set WPA IE for AssocReq with private ioctl
+- set SSID with SIOCSIWESSID
+- set channel/frequency with SIOCSIWFREQ
+- set BSSID with SIOCSIWAP
+ (this last ioctl will trigger the driver to request association)
+
+\subsection driver_wpa_ie WPA IE generation
+
+%wpa_supplicant selects which cipher suites and key management suites
+are used. Based on this information, it generates a WPA IE. This is
+provided to the driver interface in the associate call. This does not
+match with Windows NDIS drivers which generate the WPA IE
+themselves.
+
+%wpa_supplicant allows Windows NDIS-like behavior by providing the
+selected cipher and key management suites in the associate call. If
+the driver generates its own WPA IE and that differs from the one
+generated by %wpa_supplicant, the driver has to inform %wpa_supplicant
+about the used WPA IE (i.e., the one it used in (Re)Associate
+Request). This notification is done using EVENT_ASSOCINFO event (see
+wpa_supplicant.h). %wpa_supplicant is normally configured to use
+ap_scan=2 mode with drivers that control WPA IE generation and roaming.
+
+\subsection driver_events Driver events
+
+%wpa_supplicant needs to receive event callbacks when certain events
+occur (association, disassociation, Michael MIC failure, scan results
+available, PMKSA caching candidate). These events and the callback
+details are defined in wpa_supplicant.h (wpa_supplicant_event() function
+and enum wpa_event_type).
+
+On Linux, association and disassociation can use existing Wireless
+Extensions event that is reporting new AP with SIOCGIWAP
+event. Similarly, completion of a scan can be reported with SIOCGIWSCAN
+event.
+
+Michael MIC failure event was added in WE-18. Older versions of Wireless
+Extensions will need to use a custom event. Host AP driver used a custom
+event with following contents: MLME-MICHAELMICFAILURE.indication(keyid=#
+broadcast/unicast addr=addr2). This is the recommended format until
+the driver can be moved to use WE-18 mechanism.
+
+\subsection driver_wext_summary Summary of Linux Wireless Extensions use
+
+AP selection depends on ap_scan configuration:
+
+ap_scan=1:
+
+- %wpa_supplicant requests scan with SIOCSIWSCAN
+- driver reports scan complete with wireless event SIOCGIWSCAN
+- %wpa_supplicant reads scan results with SIOCGIWSCAN (multiple call if
+ a larget buffer is needed)
+- %wpa_supplicant decides which AP to use based on scan results
+- %wpa_supplicant configures driver to associate with the selected BSS
+ (SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWFREQ,
+ SIOCSIWESSID, SIOCSIWAP)
+
+ap_scan=2:
+
+- %wpa_supplicant configures driver to associate with an SSID
+ (SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWESSID)
+
+
+After this, both modes use similar steps:
+
+- optionally (or required for drivers that generate WPA/RSN IE for
+ (Re)AssocReq), driver reports association parameters (AssocReq IEs)
+ with wireless event IWEVASSOCREQIE (and optionally IWEVASSOCRESPIE)
+- driver reports association with wireless event SIOCGIWAP
+- %wpa_supplicant takes care of EAPOL frame handling (validating
+ information from associnfo and if needed, from scan results if WPA/RSN
+ IE from the Beacon frame is not reported through associnfo)

+/**
+\page eap_module EAP peer implementation
+
+Extensible Authentication Protocol (EAP) is an authentication framework
+defined in RFC 3748. %wpa_supplicant uses a separate code module for EAP
+peer implementation. This module was designed to use only a minimal set
+of direct function calls (mainly, to debug/event functions) in order for
+it to be usable in other programs. The design of the EAP
+implementation is based loosely on RFC 4137. The state machine is
+defined in this RFC and so is the interface between the peer state
+machine and methods. As such, this RFC provides useful information for
+understanding the EAP peer implementation in %wpa_supplicant.
+
+Some of the terminology used in EAP state machine is referring to
+EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
+layer being IEEE 802.1X if EAP module is built for other programs than
+%wpa_supplicant. These terms should be understood to refer to the
+lower layer as defined in RFC 4137.
+
+
+\section adding_eap_methods Adding EAP methods
+
+Each EAP method is implemented as a separate module, usually as one C
+file named eap_<name of the method>.c, e.g., eap_md5.c. All EAP
+methods use the same interface between the peer state machine and
+method specific functions. This allows new EAP methods to be added
+without modifying the core EAP state machine implementation.
+
+New EAP methods need to be registered by adding them into the build
+(Makefile) and the EAP method registration list in the
+eap_peer_register_methods() function of eap_methods.c. Each EAP
+method should use a build-time configuration option, e.g., EAP_TLS, in
+order to make it possible to select which of the methods are included
+in the build.
+
+EAP methods must implement the interface defined in eap_i.h. struct
+eap_method defines the needed function pointers that each EAP method
+must provide. In addition, the EAP type and name are registered using
+this structure. This interface is based on section 4.4 of RFC 4137.
+
+It is recommended that the EAP methods would use generic helper
+functions, eap_msg_alloc() and eap_hdr_validate() when processing
+messages. This allows code sharing and can avoid missing some of the
+needed validation steps for received packets. In addition, these
+functions make it easier to change between expanded and legacy EAP
+header, if needed.
+
+When adding an EAP method that uses a vendor specific EAP type
+(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
+must be registered by passing vendor id instead of EAP_VENDOR_IETF to
+eap_peer_method_alloc(). These methods must not try to emulate
+expanded types by registering a legacy EAP method for type 254. See
+eap_vendor_test.c for an example of an EAP method implementation that
+is implemented as an expanded type.

+\mainpage Developers' documentation for %wpa_supplicant
+
+%wpa_supplicant is a WPA Supplicant for Linux, BSD and Windows with
+support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE
+802.1X/WPA component that is used in the client stations. It
+implements key negotiation with a WPA Authenticator and it can optionally
+control roaming and IEEE 802.11 authentication/association of the wlan
+driver.
+
+The goal of this documentation and comments in the source code is to
+give enough information for other developers to understand how
+%wpa_supplicant has been implemented, how it can be modified, how new
+drivers can be supported, and how %wpa_supplicant can be ported to
+other operating systems. If any information is missing, feel free to
+contact Jouni Malinen <j@w1.fi> for more
+information. Contributions as patch files are also very welcome at the
+same address. Please note that %wpa_supplicant is licensed under dual
+license, GPLv2 or BSD at user's choice. All contributions to
+%wpa_supplicant are expected to use compatible licensing terms.
+
+The source code and read-only access to %wpa_supplicant CVS repository
+is available from the project home page at
+http://hostap.epitest.fi/wpa_supplicant/. This developers' documentation
+is also available as a PDF file from
+http://hostap.epitest.fi/wpa_supplicant/wpa_supplicant-devel.pdf .
+
+The design goal for %wpa_supplicant was to use hardware, driver, and
+OS independent, portable C code for all WPA functionality. The source
+code is divided into separate C files as shown on the \ref
+code_structure "code structure page". All hardware/driver specific
+functionality is in separate files that implement a \ref
+driver_wrapper "well-defined driver API". Information about porting
+to different target boards and operating systems is available on
+the \ref porting "porting page".
+
+EAPOL (IEEE 802.1X) state machines are implemented as a separate
+module that interacts with \ref eap_module "EAP peer implementation".
+In addition to programs aimed at normal production use,
+%wpa_supplicant source tree includes number of \ref testing_tools
+"testing and development tools" that make it easier to test the
+programs without having to setup a full test setup with wireless
+cards. These tools can also be used to implement automatic test
+suites.
+
+%wpa_supplicant implements a
+\ref ctrl_iface_page "control interface" that can be used by
+external programs to control the operations of the %wpa_supplicant
+daemon and to get status information and event notifications. There is
+a small C library that provides helper functions to facilitate the use of the
+control interface. This library can also be used with C++.

+/**
+\page porting Porting to different target boards and operating systems
+
+%wpa_supplicant was designed to be easily portable to different
+hardware (board, CPU) and software (OS, drivers) targets. It is
+already used with number of operating systems and numerous wireless
+card models and drivers. The main %wpa_supplicant repository includes
+support for Linux, FreeBSD, and Windows. In addition, at least VxWorks,
+PalmOS, Windows CE, and Windows Mobile are supported in separate
+repositories. On the hardware
+side, %wpa_supplicant is used on various systems: desktops, laptops,
+PDAs, and embedded devices with CPUs including x86, PowerPC,
+arm/xscale, and MIPS. Both big and little endian configurations are
+supported.
+
+
+\section ansi_c_extra Extra functions on top of ANSI C
+
+%wpa_supplicant is mostly using ANSI C functions that are available on
+most targets. However, couple of additional functions that are common
+on modern UNIX systems are used. Number of these are listed with
+prototypes in common.h (the #ifdef CONFIG_ANSI_C_EXTRA block). These
+functions may need to be implemented or at least defined as macros to
+native functions in the target OS or C library.
+
+Many of the common ANSI C functions are used through a wrapper
+definitions in os.h to allow these to be replaced easily with a
+platform specific version in case standard C libraries are not
+available. In addition, os.h defines couple of common platform
+specific functions that are implemented in os_unix.c for UNIX like
+targets and in os_win32.c for Win32 API. If the target platform does
+not support either of these examples, a new os_*.c file may need to be
+added.
+
+Unless OS_NO_C_LIB_DEFINES is defined, the standard ANSI C and POSIX
+functions are used by defining the os_*() wrappers to use them
+directly in order to avoid extra cost in size and speed. If the target
+platform needs different versions of the functions, os.h can be
+modified to define the suitable macros or alternatively,
+OS_NO_C_LIB_DEFINES may be defined for the build and the wrapper
+functions can then be implemented in a new os_*.c wrapper file.
+
+common.h defines number of helper macros for handling integers of
+different size and byte order. Suitable version of these definitions
+may need to be added for the target platform.
+
+
+\section configuration_backend Configuration backend
+
+%wpa_supplicant implements a configuration interface that allows the
+backend to be easily replaced in order to read configuration data from
+a suitable source depending on the target platform. config.c
+implements the generic code that can be shared with all configuration
+backends. Each backend is implemented in its own config_*.c file.
+
+The included config_file.c backend uses a text file for configuration
+and config_winreg.c uses Windows registry. These files can be used as
+an example for a new configuration backend if the target platform uses
+different mechanism for configuration parameters. In addition,
+config_none.c can be used as an empty starting point for building a
+new configuration backend.
+
+
+\section driver_iface_porting Driver interface
+
+Unless the target OS and driver is already supported, most porting
+projects have to implement a driver wrapper. This may be done by
+adding a new driver interface module or modifying an existing module
+(driver_*.c) if the new target is similar to one of them. \ref
+driver_wrapper "Driver wrapper implementation" describes the details
+of the driver interface and discusses the tasks involved in porting
+this part of %wpa_supplicant.
+
+
+\section l2_packet_porting l2_packet (link layer access)
+
+%wpa_supplicant needs to have access to sending and receiving layer 2
+(link layer) packets with two Ethertypes: EAP-over-LAN (EAPOL) 0x888e
+and RSN pre-authentication 0x88c7. l2_packet.h defines the interfaces
+used for this in the core %wpa_supplicant implementation.
+
+If the target operating system supports a generic mechanism for link
+layer access, that is likely the best mechanism for providing the
+needed functionality for %wpa_supplicant. Linux packet socket is an
+example of such a generic mechanism. If this is not available, a
+separate interface may need to be implemented to the network stack or
+driver. This is usually an intermediate or protocol driver that is
+operating between the device driver and the OS network stack. If such
+a mechanism is not feasible, the interface can also be implemented
+directly in the device driver.
+
+The main %wpa_supplicant repository includes l2_packet implementations
+for Linux using packet sockets (l2_packet_linux.c), more portable
+version using libpcap/libdnet libraries (l2_packet_pcap.c; this
+supports WinPcap, too), and FreeBSD specific version of libpcap
+interface (l2_packet_freebsd.c).
+
+If the target operating system is supported by libpcap (receiving) and
+libdnet (sending), l2_packet_pcap.c can likely be used with minimal or
+no changes. If this is not a case or a proprietary interface for link
+layer is required, a new l2_packet module may need to be
+added. Alternatively, struct wpa_driver_ops::send_eapol() handler can
+be used to override the l2_packet library if the link layer access is
+integrated with the driver interface implementation.
+
+
+\section eloop_porting Event loop
+
+%wpa_supplicant uses a single process/thread model and an event loop
+to provide callbacks on events (registered timeout, received packet,
+signal). eloop.h defines the event loop interface. eloop.c is an
+implementation of such an event loop using select() and sockets. This
+is suitable for most UNIX/POSIX systems. When porting to other
+operating systems, it may be necessary to replace that implementation
+with OS specific mechanisms that provide similar functionality.
+
+
+\section ctrl_iface_porting Control interface
+
+%wpa_supplicant uses a \ref ctrl_iface_page "control interface"
+to allow external processed
+to get status information and to control the operations. Currently,
+this is implemented with socket based communication; both UNIX domain
+sockets and UDP sockets are supported. If the target OS does not
+support sockets, this interface will likely need to be modified to use
+another mechanism like message queues. The control interface is
+optional component, so it is also possible to run %wpa_supplicant
+without porting this part.
+
+The %wpa_supplicant side of the control interface is implemented in
+ctrl_iface.c. Matching client side is implemented as a control
+interface library in wpa_ctrl.c.
+
+
+\section entry_point Program entry point
+
+%wpa_supplicant defines a set of functions that can be used to
+initialize main supplicant processing. Each operating system has a
+mechanism for starting new processing or threads. This is usually a
+function with a specific set of arguments and calling convention. This
+function is responsible on initializing %wpa_supplicant.
+
+main.c includes an entry point for UNIX-like operating system, i.e.,
+main() function that uses command line arguments for setting
+parameters for %wpa_supplicant. When porting to other operating
+systems, similar OS-specific entry point implementation is needed. It
+can be implemented in a new file that is then linked with
+%wpa_supplicant instead of main.o. main.c is also a good example on
+how the initialization process should be done.
+
+The supplicant initialization functions are defined in
+wpa_supplicant_i.h. In most cases, the entry point function should
+start by fetching configuration parameters. After this, a global
+%wpa_supplicant context is initialized with a call to
+wpa_supplicant_init(). After this, existing network interfaces can be
+added with wpa_supplicant_add_iface(). wpa_supplicant_run() is then
+used to start the main event loop. Once this returns at program
+termination time, wpa_supplicant_deinit() is used to release global
+context data.
+
+wpa_supplicant_add_iface() and wpa_supplicant_remove_iface() can be
+used dynamically to add and remove interfaces based on when
+%wpa_supplicant processing is needed for them. This can be done, e.g.,
+when hotplug network adapters are being inserted and ejected. It is
+also possible to do this when a network interface is being
+enabled/disabled if it is desirable that %wpa_supplicant processing
+for the interface is fully enabled/disabled at the same time.
+
+
+\section simple_build Simple build example
+
+One way to start a porting project is to begin with a very simple
+build of %wpa_supplicant with WPA-PSK support and once that is
+building correctly, start adding features.
+
+Following command can be used to build very simple version of
+%wpa_supplicant:
+
+\verbatim
+cc -o wpa_supplicant config.c eloop.c common.c md5.c rc4.c sha1.c \
+ config_none.c l2_packet_none.c tls_none.c wpa.c preauth.c \
+ aes_wrap.c wpa_supplicant.c events.c main_none.c drivers.c
+\endverbatim
+
+The end result is not really very useful since it uses empty functions
+for configuration parsing and layer 2 packet access and does not
+include a driver interface. However, this is a good starting point
+since the build is complete in the sense that all functions are
+present and this is easy to configure to a build system by just
+including the listed C files.
+
+Once this version can be build successfully, the end result can be
+made functional by adding a proper program entry point (main*.c),
+driver interface (driver_*.c and matching CONFIG_DRIVER_* define for
+registration in drivers.c), configuration parser/writer (config_*.c),
+and layer 2 packet access implementation (l2_packet_*.c). After these
+components have been added, the end result should be a working
+WPA/WPA2-PSK enabled supplicant.
+
+After the basic functionality has been verified to work, more features
+can be added by linking in more files and defining C pre-processor
+defines. Currently, the best source of information for what options
+are available and which files needs to be included is in the Makefile
+used for building the supplicant with make. Similar configuration will
+be needed for build systems that either use different type of make
+tool or a GUI-based project configuration.

+
+[ \ref eapol_test "eapol_test" |
+\ref preauth_test "preauth_test" |
+\ref driver_test "driver_test" |
+\ref unit_tests "Unit tests" ]
+
+%wpa_supplicant source tree includes number of testing and development
+tools that make it easier to test the programs without having to setup
+a full test setup with wireless cards. In addition, these tools can be
+used to implement automatic tests suites.
+
+\section eapol_test eapol_test - EAP peer and RADIUS client testing
+
+eapol_test is a program that links together the same EAP peer
+implementation that %wpa_supplicant is using and the RADIUS
+authentication client code from hostapd. In addition, it has minimal
+glue code to combine these two components in similar ways to IEEE
+802.1X/EAPOL Authenticator state machines. In other words, it
+integrates IEEE 802.1X Authenticator (normally, an access point) and
+IEEE 802.1X Supplicant (normally, a wireless client) together to
+generate a single program that can be used to test EAP methods without
+having to setup an access point and a wireless client.
+
+The main uses for eapol_test are in interoperability testing of EAP
+methods against RADIUS servers and in development testing for new EAP
+methods. It can be easily used to automate EAP testing for
+interoperability and regression since the program can be run from
+shell scripts without require additional test components apart from a
+RADIUS server. For example, the automated EAP tests described in
+eap_testing.txt are implemented with eapol_test. Similarly, eapol_test
+could be used to implement an automated regression test suite for a
+RADIUS authentication server.
+
+eapol_test uses the same build time configuration file, .config, as
+%wpa_supplicant. This file is used to select which EAP methods are
+included in eapol_test. This program is not built with the default
+Makefile target, so a separate make command needs to be used to
+compile the tool:
+
+\verbatim
+make eapol_test
+\endverbatim
+
+The resulting eapol_test binary has following command like options:
+
+\verbatim
+usage:
+eapol_test [-nWS] -c<conf> [-a<AS IP>] [-p<AS port>] [-s<AS secret>] \
+ [-r<count>] [-t<timeout>] [-C<Connect-Info>] \
+ [-M<client MAC address>]
+eapol_test scard
+eapol_test sim <PIN> <num triplets> [debug]
+
+options:
+ -c<conf> = configuration file
+ -a<AS IP> = IP address of the authentication server, default 127.0.0.1
+ -p<AS port> = UDP port of the authentication server, default 1812
+ -s<AS secret> = shared secret with the authentication server, default 'radius'
+ -r<count> = number of re-authentications
+ -W = wait for a control interface monitor before starting
+ -S = save configuration after authentiation
+ -n = no MPPE keys expected
+ -t<timeout> = sets timeout in seconds (default: 30 s)
+ -C<Connect-Info> = RADIUS Connect-Info (default: CONNECT 11Mbps 802.11b)
+ -M<client MAC address> = Set own MAC address (Calling-Station-Id,
+ default: 02:00:00:00:00:01)
+\endverbatim
+
+
+As an example,
+\verbatim
+eapol_test -ctest.conf -a127.0.0.1 -p1812 -ssecret -r1
+\endverbatim
+tries to complete EAP authentication based on the network
+configuration from test.conf against the RADIUS server running on the
+local host. A re-authentication is triggered to test fast
+re-authentication. The configuration file uses the same format for
+network blocks as %wpa_supplicant.
+
+
+\section preauth_test preauth_test - WPA2 pre-authentication and EAP peer testing
+
+preauth_test is similar to eapol_test in the sense that in combines
+EAP peer implementation with something else, in this case, with WPA2
+pre-authentication. This tool can be used to test pre-authentication
+based on the code that %wpa_supplicant is using. As such, it tests
+both the %wpa_supplicant implementation and the functionality of an
+access point.
+
+preauth_test is built with:
+
+\verbatim
+make preauth_test
+\endverbatim
+
+and it uses following command line arguments:
+
+\verbatim
+usage: preauth_test <conf> <target MAC address> <ifname>
+\endverbatim
+
+For example,
+\verbatim
+preauth_test test.conf 02:11:22:33:44:55 eth0
+\endverbatim
+would use network configuration from test.conf to try to complete
+pre-authentication with AP using BSSID 02:11:22:33:44:55. The
+pre-authentication packets would be sent using the eth0 interface.
+
+
+\section driver_test driver_test - driver interface for testing wpa_supplicant
+
+%wpa_supplicant was designed to support number of different ways to
+communicate with a network device driver. This design uses \ref
+driver_wrapper "driver interface API" and number of driver interface
+implementations. One of these is driver_test.c, i.e., a test driver
+interface that is actually not using any drivers. Instead, it provides
+a mechanism for running %wpa_supplicant without having to have a
+device driver or wireless LAN hardware for that matter.
+
+driver_test can be used to talk directly with hostapd's driver_test
+component to create a test setup where one or more clients and access
+points can be tested within one test host and without having to have
+multiple wireless cards. This makes it easier to test the core code in
+%wpa_supplicant, and hostapd for that matter. Since driver_test uses
+the same driver API than any other driver interface implementation,
+the core code of %wpa_supplicant and hostapd can be tested with the
+same coverage as one would get when using real wireless cards. The
+only area that is not tested is the driver interface implementation
+(driver_*.c).
+
+Having the possibility to use simulated network components makes it
+much easier to do development testing while adding new features and to
+reproduce reported bugs. As such, it is often easiest to just do most
+of the development and bug fixing without using real hardware. Once
+the driver_test setup has been used to implement a new feature or fix
+a bug, the end result can be verified with wireless LAN cards. In many
+cases, this may even be unnecessary, depending on what area the
+feature/bug is relating to. Of course, changes to driver interfaces
+will still require use of real hardware.
+
+Since multiple components can be run within a single host, testing of
+complex network configuration, e.g., large number of clients
+association with an access point, becomes quite easy. All the tests
+can also be automated without having to resort to complex test setup
+using remote access to multiple computers.
+
+driver_test can be included in the %wpa_supplicant build in the same
+way as any other driver interface, i.e., by adding the following line
+into .config:
+
+\verbatim
+CONFIG_DRIVER_TEST=y
+\endverbatim
+
+When running %wpa_supplicant, the test interface is selected by using
+\a -Dtest command line argument. The interface name (\a -i argument)
+can be selected arbitrarily, i.e., it does not need to match with any
+existing network interface. The interface name is used to generate a
+MAC address, so when using multiple clients, each should use a
+different interface, e.g., \a sta1, \a sta2, and so on.
+
+%wpa_supplicant and hostapd are configured in the same way as they
+would be for normal use. Following example shows a simple test setup
+for WPA-PSK.
+
+hostapd is configured with following psk-test.conf configuration file:
+
+\verbatim
+driver=test
+
+interface=ap1
+logger_stdout=-1
+logger_stdout_level=0
+debug=2
+dump_file=/tmp/hostapd.dump
+
+test_socket=/tmp/Test/ap1
+
+ssid=jkm-test-psk
+
+wpa=1
+wpa_key_mgmt=WPA-PSK
+wpa_pairwise=TKIP
+wpa_passphrase=12345678
+\endverbatim
+
+and started with following command:
+
+\verbatim
+hostapd psk-test.conf
+\endverbatim
+
+%wpa_supplicant uses following configuration file:
+
+\verbatim
+driver_param=test_socket=/tmp/Test/ap1
+
+network={
+ ssid="jkm-test-psk"
+ key_mgmt=WPA-PSK
+ psk="12345678"
+}
+\endverbatim
+
+%wpa_supplicant can then be started with following command:
+
+\verbatim
+wpa_supplicant -Dtest -cpsk-test.conf -ista1 -ddK
+\endverbatim
+
+If run without debug information, i.e., with
+
+\verbatim
+wpa_supplicant -Dtest -cpsk-test.conf -ista1
+\endverbatim
+
+%wpa_supplicant completes authentication and prints following events:
+
+\verbatim
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a
+WPA: Key negotiation completed with 02:b8:a6:62:08:5a [PTK=TKIP GTK=TKIP]
+CTRL-EVENT-CONNECTED - Connection to 02:b8:a6:62:08:5a completed (auth)
+\endverbatim
+
+If test setup is using multiple clients, it is possible to run
+multiple %wpa_supplicant processes. Alternatively, the support for
+multiple interfaces can be used with just one process to save some
+resources on single-CPU systems. For example, following command runs
+two clients:
+
+\verbatim
+./wpa_supplicant -Dtest -cpsk-test.conf -ista1 \
+ -N -Dtest -cpsk-test.conf -ista2
+\endverbatim
+
+This shows following event log:
+
+\verbatim
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a
+WPA: Key negotiation completed with 02:b8:a6:62:08:5a [PTK=TKIP GTK=TKIP]
+CTRL-EVENT-CONNECTED - Connection to 02:b8:a6:62:08:5a completed (auth)
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a
+WPA: Key negotiation completed with 02:b8:a6:62:08:5a [PTK=TKIP GTK=TKIP]
+CTRL-EVENT-CONNECTED - Connection to 02:b8:a6:62:08:5a completed (auth)
+\endverbatim
+
+hostapd shows this with following events:
+
+\verbatim
+ap1: STA 02:b5:64:63:30:63 IEEE 802.11: associated
+ap1: STA 02:b5:64:63:30:63 WPA: pairwise key handshake completed (WPA)
+ap1: STA 02:b5:64:63:30:63 WPA: group key handshake completed (WPA)
+ap1: STA 02:2a:c4:18:5b:f3 IEEE 802.11: associated
+ap1: STA 02:2a:c4:18:5b:f3 WPA: pairwise key handshake completed (WPA)
+ap1: STA 02:2a:c4:18:5b:f3 WPA: group key handshake completed (WPA)
+\endverbatim
+
+By default, driver_param is simulating a driver that uses the WPA/RSN
+IE generated by %wpa_supplicant. Driver-generated IE and AssocInfo
+events can be tested by adding \a use_associnfo=1 to the \a driver_param
+line in the configuration file. For example:
+
+\verbatim
+driver_param=test_socket=/tmp/Test/ap1 use_associnfo=1
+\endverbatim
+
+
+\section unit_tests Unit tests
+
+Number of the components (.c files) used in %wpa_supplicant define
+their own unit tests for automated validation of the basic
+functionality. Most of the tests for cryptographic algorithms are
+using standard test vectors to validate functionality. These tests can
+be useful especially when verifying port to a new CPU target.
+
+In most cases, these tests are implemented in the end of the same file
+with functions that are normally commented out, but ca be included by
+defining a pre-processor variable when building the file separately.
+The details of the needed build options are included in the Makefile
+(test-* targets). All automated unit tests can be run with
+
+\verbatim
+make tests
+\endverbatim
+
+This make target builds and runs each test and terminates with zero
+exit code if all tests were completed successfully.

+Automatic regression and interoperability testing of wpa_supplicant's
+IEEE 802.1X/EAPOL authentication
+
+Test program:
+- Linked some parts of IEEE 802.1X Authenticator implementation from
+ hostapd (RADIUS client and RADIUS processing, EAP<->RADIUS
+ encapsulation/decapsulation) into wpa_supplicant.
+- Replaced wpa_supplicant.c and wpa.c with test code that trigger
+ IEEE 802.1X authentication automatically without need for wireless
+ client card or AP.
+- For EAP methods that generate keying material, the key derived by the
+ Supplicant is verified to match with the one received by the (now
+ integrated) Authenticator.
+
+The full automated test suite can now be run in couple of seconds, but
+I'm more than willing to add new RADIUS authentication servers to make
+this take a bit more time.. ;-) As an extra bonus, this can also be
+seen as automatic regression/interoperability testing for the RADIUS
+server, too.
+
+In order for me to be able to use a new authentication server, the
+server need to be available from Internet (at least from one static IP
+address) and I will need to get suitable user name/password pairs,
+certificates, and private keys for testing use. Other alternative
+would be to get an evaluation version of the server so that I can
+install it on my own test setup. If you are interested in providing
+either server access or evaluation version, please contact me
+(j@w1.fi).

+1) PEAPv1 required new label, "client PEAP encryption" instead of "client EAP
+ encryption", during key derivation (requires phase1="peaplabel=1" in the
+ network configuration in wpa_supplicant.conf)
+2) used FreeRADIUS as inner auth server
+3) required a patch to FreeRADIUS to fix EAP-SIM
+5) PEAPv1 required termination of negotiation on tunneled EAP-Success and new
+ label in key deriviation
+ (phase1="peap_outer_success=0 peaplabel=1") (in "IETF Draft 5" mode)
+6) Authenticator simulator required patching for handling Access-Accept within
+ negotiation (for the first EAP-Success of LEAP)
+7) EAP-PSK is not included in FreeRADIUS distribution; used external
+ rlm_eap_psk implementation from
+ http://perso.rd.francetelecom.fr/bersani/EAP_PSK/
+ EAP-PSKWindowsimplementations.html
+8) PEAPv1 used non-standard version negotiation (client had to force v1 even
+ though server reported v0 as the highest supported version)

+ * This l2_packet implementation is explicitly for WinPcap and Windows events.
+ * l2_packet_pcap.c has support for WinPcap, but it requires polling to receive
+ * frames which means relatively long latency for EAPOL RX processing. The
+ * implementation here uses a separate thread to allow WinPcap to be receiving
+ * all the time to reduce latency for EAPOL receiving from about 100 ms to 3 ms
+ * when comparing l2_packet_pcap.c to l2_packet_winpcap.c. Extra sleep of 50 ms
+ * is added in to receive thread whenever no EAPOL frames has been received for
+ * a while. Whenever an EAPOL handshake is expected, this sleep is removed.
+ *
+ * The RX thread receives a frame and signals main thread through Windows event
+ * about the availability of a new frame. Processing the received frame is
+ * synchronized with pair of Windows events so that no extra buffer or queuing
+ * mechanism is needed. This implementation requires Windows specific event
+ * loop implementation, i.e., eloop_win.c.
+ *
+ * WinPcap has pcap_getevent() that could, in theory at least, be used to
+ * implement this kind of waiting with a simpler single-thread design. However,
+ * that event handle is not really signaled immediately when receiving each
+ * frame, so it does not really work for this kind of use.

+-----------------
+Modified 7/98
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+ void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+ void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it. This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'

+To do:
+- hostap: try other roaming modes
+ NOTE: current mode (manual roaming) does not really roam at all..
+ Firmware did not notice the current AP disappearing..
+- add support for WPA with ap_scan=0 (update selected cipher etc. based on
+ AssocInfo; make sure these match with configuration)
+- optional security separation (build time option): run EAPOL state machines
+ as non-root (need to add something like socketpair between privileged root
+ process and non-root handler; send EAPOL packets between processes
+ and send keying data from non-root -> privileged)
+ EAPOL-Key processing (WPA & WEP keys) could be in privileged part
+ at least in the beginning; some parts might end up being moved to
+ non-root part eventually
+- consider closing smart card / PCSC connection when EAP-SIM/EAP-AKA
+ authentication has been completed (cache scard data based on serial#(?)
+ and try to optimize next connection if the same card is present for next
+ auth)
+- EAP-AKA: AT_CHECKCODE
+- EAP-SIM/AKA: AT_RESULT_IND
+- on disconnect event, could try to associate with another AP if one is
+ present in scan results; would need to update scan results periodically..
+- if driver/hw is not WPA2 capable, must remove WPA_PROTO_RSN flag from
+ ssid->proto fields to avoid detecting downgrade attacks when the driver
+ is not reporting RSN IE, but msg 3/4 has one
+- Cisco AP and non-zero keyidx for unicast -> map to broadcast
+ (actually, this already works with driver_ndis; so maybe just change
+ driver_*.c to do the mapping for drivers that cannot handle non-zero keyidx
+ for unicast); worked also with Host AP driver and madwifi
+- IEEE 802.1X and key update with driver_ndis?? wpa_supplicant did not seem
+ to see unencrypted EAPOL-Key frames at all..
+- EAP-PAX with PAX_SEC
+- EAP (RFC 3748)
+ * OTP Extended Responses (Sect. 5.5)
+- test what happens if authenticator sends EAP-Success before real EAP
+ authentication ("canned" Success); this should be ignored based on
+ RFC 3748 Sect. 4.2
+- test compilation with gcc -W options (more warnings?)
+ (Done once; number of unused function arguments still present)
+- add proper support for using dot11RSNAConfigSATimeout
+- ctrl_iface: get/set/remove blob
+- use doc/docbook/*.sgml and docbook2{txt,html,pdf} to replace README and
+ web pages including the same information.. i.e., have this information only
+ in one page; how to build a PDF file with all the SGML included?
+- test wait-for-interface and daemonize combinations with number of driver
+ interfaces
+ * 'test' worked with WPA-PSK
+- EAP-POTP/RSA SecurID profile (draft-nystrom-eap-potp-03.txt)
+- document wpa_gui build and consider adding it to 'make install'
+- test madwifi with pairwise=TKIP group=WEP104
+- possibility to link in WPA Authenticator state machine to wpa_supplicant
+ (new STAKey handshake, WPA2 IBSS)
+- consider merging hostapd and wpa_supplicant PMKSA cache implementations
+- add support for configuring password for MSCHAPv2 as NtPasswordHash in
+ the same way as was added to hostapd (hash:<hex value>)
+- test_driver: configure directory and create AP-<mac> and STA-<mac> files
+ there to allow scanning multiple APs (e.g., for testing pre-auth and PMKSA
+ caching testing) and to exchange STA-STA EAPOL frames
+- consider adding generic buffer functionality that could be used in number
+ of places
+ * allocate buffer (with default max size), allow reserving head room to
+ make it possible to add a header without having to reallocate buffer
+ * reallocate buffer (add head and/or tail room)
+ * ref count and free when count=0 ?
+ * add data (to tail): re-alloc more tailroom if needed and copy new data
+ * error flag so that caller can do multiple add()s and only in the end
+ check whether something has failed; this should make error handling
+ simpler
+- consider redesigning pending EAP requests (identity/password/otp from
+ ctrl_iface) by moving the retrying of the previous request into EAP
+ state machine so that EAPOL state machine is not needed for this
+- rfc4284.txt (network selection for eap)
+- www pages about configuring wpa_supplicant:
+ * global options (ap_scan, ctrl_interfaces) based on OS/driver
+ * network block
+ * key_mgmt selection
+ * WPA parameters
+ * EAP options (one page for each method)
+ * "configuration wizard" (step 1: select OS, step 2: select driver, ...) to
+ generate example configuration
+- error path in rsn_preauth_init: should probably deinit l2_packet handlers
+ if something fails; does something else need deinit?
+- consider moving SIM card functionality (IMSI fetching) away from eap.c;
+ this should likely happen before EAP is initialized for authentication;
+ now IMSI is read only after receiving EAP-Identity/Request, but since it is
+ really needed for all cases, reading IMSI and generating Identity string
+ could very well be done before EAP has been started
+- test all allowed EAP Phase 2 methods (i.e., anything else than PEAP, TTLS,
+ FAST): SIM AKA PAX PSK LEAP; if these work, include in eap_testing.txt; if
+ not, either fix or make eap_allowed_phase2_type reject
+- try to work around race in receiving association event and first EAPOL
+ message
+- helper function to do memcmp(addr, "\x00\x00\x00\x00\x00\x00", ETH_ALEN)
+- add wpa_secure_memzero() macro and secure implementation (volatile u8*) to
+ clear memory; this would be used to clear temporary buffers containing
+ private data (e.g., keys); the macro can be defined to NOP in order to save
+ space (i.e., no code should depend on the macro doing something)
+- make sure that TLS session cache is not shared between EAP types or if it
+ is, that the cache entries are bound to only one EAP type; e.g., cache entry
+ created with EAP-TLS must not be allowed to do fast re-auth with EAP-TTLS
+- consider moving eap_tls_build_ack() call into eap_tls_process_helper()
+ (it seems to be called always if helper returns 1)
+ * could need to modify eap_{ttls,peap,fast}_decrypt to do same
+- add support for fetching full user cert chain from Windows certificate
+ stores even when there are intermediate CA certs that are not in the
+ configured ca_cert store (e.g., ROOT) (they could be, e.g., in CA store)
+
+
+0.6.x branch:
+- clean up common.[ch]
+- change TLS/crypto library interface to use a structure of function
+ pointers and helper inline functions (like driver_ops) instead of
+ requiring every TLS wrapper to implement all functions
+- move from CVS to git (0.3.x, 0.4.x, 0.5.x releases will continue
+ to be updated only on CVS)
+- move files into subdirectories and combine wpa_supplicant and hostapd
+ into a repository that matches in directory structure with the release
+ tarballs
+ (subdirs: eap_common, eap_peer, eap_server, driver, driver_ap, ...)
+- make it clearer that EAP server/peer can be used as a separate library
+ for other programs
+- add support for encrypted configuration fields (e.g., password, psk,
+ passphrase, pin)
+- wpa_gui: add support for setting and showing priority, id_str, auth_alg
+ (open/shared for static WEP)

+/*
+ * Initial APIs (1996 -> onward) :
+ * -----------------------------
+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands. This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ * # net/core/dev.c (two place + add include)
+ * # net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ * # net/core/dev.c (two other places)
+ * # include/linux/netdevice.h (one place)
+ * # include/linux/proc_fs.h (one place)
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * This file is only concerned with the user space API and common definitions.
+ * The new driver API is defined and documented in :
+ * # include/net/iw_handler.h
+ *
+ * Note as well that /proc/net/wireless implementation has now moved in :
+ * # net/core/wireless.c
+ *
+ * Wireless Events (2002 -> onward) :
+ * --------------------------------
+ * Events are defined at the end of this file, and implemented in :
+ * # net/core/wireless.c
+ *
+ * Other comments :
+ * --------------
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...

+##### Example wpa_supplicant configuration file ###############################
+#
+# This file describes configuration file format and lists all available option.
+# Please also take a look at simpler configuration examples in 'examples'
+# subdirectory.
+#
+# Empty lines and lines starting with # are ignored
+
+# NOTE! This file may contain password information and should probably be made
+# readable only by root user on multiuser systems.
+
+# Note: All file paths in this configuration file should use full (absolute,
+# not relative to working directory) path in order to allow working directory
+# to be changed. This can happen if wpa_supplicant is run in the background.
+
+# Whether to allow wpa_supplicant to update (overwrite) configuration
+#
+# This option can be used to allow wpa_supplicant to overwrite configuration
+# file whenever configuration is changed (e.g., new network block is added with
+# wpa_cli or wpa_gui, or a password is changed). This is required for
+# wpa_cli/wpa_gui to be able to store the configuration changes permanently.
+# Please note that overwriting configuration file will remove the comments from
+# it.
+#update_config=1
+
+# global configuration (shared by all network blocks)
+#
+# Parameters for the control interface. If this is specified, wpa_supplicant
+# will open a control interface that is available for external programs to
+# manage wpa_supplicant. The meaning of this string depends on which control
+# interface mechanism is used. For all cases, the existance of this parameter
+# in configuration is used to determine whether the control interface is
+# enabled.
+#
+# For UNIX domain sockets (default on Linux and BSD): This is a directory that
+# will be created for UNIX domain sockets for listening to requests from
+# external programs (CLI/GUI, etc.) for status information and configuration.
+# The socket file will be named based on the interface name, so multiple
+# wpa_supplicant processes can be run at the same time if more than one
+# interface is used.
+# /var/run/wpa_supplicant is the recommended directory for sockets and by
+# default, wpa_cli will use it when trying to connect with wpa_supplicant.
+#
+# Access control for the control interface can be configured by setting the
+# directory to allow only members of a group to use sockets. This way, it is
+# possible to run wpa_supplicant as root (since it needs to change network
+# configuration and open raw sockets) and still allow GUI/CLI components to be
+# run as non-root users. However, since the control interface can be used to
+# change the network configuration, this access needs to be protected in many
+# cases. By default, wpa_supplicant is configured to use gid 0 (root). If you
+# want to allow non-root users to use the control interface, add a new group
+# and change this value to match with that group. Add users that should have
+# control interface access to this group. If this variable is commented out or
+# not included in the configuration file, group will not be changed from the
+# value it got by default when the directory or socket was created.
+#
+# When configuring both the directory and group, use following format:
+# DIR=/var/run/wpa_supplicant GROUP=wheel
+# DIR=/var/run/wpa_supplicant GROUP=0
+# (group can be either group name or gid)
+#
+# For UDP connections (default on Windows): The value will be ignored. This
+# variable is just used to select that the control interface is to be created.
+# The value can be set to, e.g., udp (ctrl_interface=udp)
+#
+# For Windows Named Pipe: This value can be used to set the security descriptor
+# for controlling access to the control interface. Security descriptor can be
+# set using Security Descriptor String Format (see http://msdn.microsoft.com/
+# library/default.asp?url=/library/en-us/secauthz/security/
+# security_descriptor_string_format.asp). The descriptor string needs to be
+# prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty
+# DACL (which will reject all connections). See README-Windows.txt for more
+# information about SDDL string format.
+#
+ctrl_interface=/var/run/wpa_supplicant
+
+# IEEE 802.1X/EAPOL version
+# wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines
+# EAPOL version 2. However, there are many APs that do not handle the new
+# version number correctly (they seem to drop the frames completely). In order
+# to make wpa_supplicant interoperate with these APs, the version number is set
+# to 1 by default. This configuration value can be used to set it to the new
+# version (2).
+eapol_version=1
+
+# AP scanning/selection
+# By default, wpa_supplicant requests driver to perform AP scanning and then
+# uses the scan results to select a suitable AP. Another alternative is to
+# allow the driver to take care of AP scanning and selection and use
+# wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
+# information from the driver.
+# 1: wpa_supplicant initiates scanning and AP selection
+# 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
+# parameters (e.g., WPA IE generation); this mode can also be used with
+# non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
+# APs (i.e., external program needs to control association). This mode must
+# also be used when using wired Ethernet drivers.
+# 2: like 0, but associate with APs using security policy and SSID (but not
+# BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
+# enable operation with hidden SSIDs and optimized roaming; in this mode,
+# the network blocks in the configuration file are tried one by one until
+# the driver reports successful association; each network block should have
+# explicit security policy (i.e., only one option in the lists) for
+# key_mgmt, pairwise, group, proto variables
+ap_scan=1
+
+# EAP fast re-authentication
+# By default, fast re-authentication is enabled for all EAP methods that
+# support it. This variable can be used to disable fast re-authentication.
+# Normally, there is no need to disable this.

+# OpenSSL Engine support

+#
+# id_str: Network identifier string for external scripts. This value is passed
+# to external action script through wpa_cli as WPA_ID_STR environment
+# variable to make it easier to do network specific configuration.
+#
+# ssid: SSID (mandatory); either as an ASCII string with double quotation or
+# as hex string; network name
+#
+# scan_ssid:
+# 0 = do not scan this SSID with specific Probe Request frames (default)
+# 1 = scan with SSID-specific Probe Request frames (this can be used to
+# find APs that do not accept broadcast SSID or use multiple SSIDs;
+# this will add latency to scanning, so enable this only when needed)
+#
+# bssid: BSSID (optional); if set, this network block is used only when
+# associating with the AP using the configured BSSID
+#
+# priority: priority group (integer)
+# By default, all networks will get same priority group (0). If some of the
+# networks are more desirable, this field can be used to change the order in
+# which wpa_supplicant goes through the networks when selecting a BSS. The
+# priority groups will be iterated in decreasing priority (i.e., the larger the
+# priority value, the sooner the network is matched against the scan results).
+# Within each priority group, networks will be selected based on security
+# policy, signal strength, etc.
+# Please note that AP scanning with scan_ssid=1 and ap_scan=2 mode are not
+# using this priority to select the order for scanning. Instead, they try the

+# 0 = infrastructure (Managed) mode, i.e., associate with an AP (default)
+# 1 = IBSS (ad-hoc, peer-to-peer)
+# Note: IBSS can only be used with key_mgmt NONE (plaintext and static WEP)
+# and key_mgmt=WPA-NONE (fixed group key TKIP/CCMP). In addition, ap_scan has
+# to be set to 2 for IBSS. WPA-None requires following network block options:
+# proto=WPA, key_mgmt=WPA-NONE, pairwise=NONE, group=TKIP (or CCMP, but not
+# both), and psk must also be set.
+#
+# frequency: Channel frequency in megahertz (MHz) for IBSS, e.g.,
+# 2412 = IEEE 802.11b/g channel 1. This value is used to configure the initial
+# channel for IBSS (adhoc) networks. It is ignored in the infrastructure mode.
+# In addition, this value is only used by the station that creates the IBSS. If
+# an IBSS network with the configured SSID is already present, the frequency of
+# the network will be used instead of this configured value.
+#
+# proto: list of accepted protocols
+# WPA = WPA/IEEE 802.11i/D3.0
+# RSN = WPA2/IEEE 802.11i (also WPA2 can be used as an alias for RSN)

+# ca_cert: File path to CA certificate file (PEM/DER). This file can have one

+# EAP-TLS/TTLS/PEAP. Full path should be used since working directory may
+# change when wpa_supplicant is run in the background.
+# On Windows, trusted CA certificates can be loaded from the system
+# certificate store by setting this to cert_store://<name>, e.g.,
+# ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT".
+# Note that when running wpa_supplicant as an application, the user
+# certificate store (My user account) is used, whereas computer store
+# (Computer account) is used when running wpasvc as a service.
+# ca_path: Directory path for CA certificate files (PEM). This path may
+# contain multiple CA certificates in OpenSSL format. Common use for this
+# is to point to system trusted CA list which is often installed into
+# directory like /etc/ssl/certs. If configured, these certificates are
+# added to the list of trusted CAs. ca_cert may also be included in that
+# case, but it is not required.
+# client_cert: File path to client certificate file (PEM/DER)
+# Full path should be used since working directory may change when
+# wpa_supplicant is run in the background.
+# Alternatively, a named configuration blob can be used by setting this
+# to blob://<blob name>.
+# private_key: File path to client private key file (PEM/DER/PFX)
+# When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
+# commented out. Both the private key and certificate will be read from
+# the PKCS#12 file in this case. Full path should be used since working
+# directory may change when wpa_supplicant is run in the background.
+# Windows certificate store can be used by leaving client_cert out and
+# configuring private_key in one of the following formats:
+# cert://substring_to_match
+# hash://certificate_thumbprint_in_hex
+# for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
+# Note that when running wpa_supplicant as an application, the user
+# certificate store (My user account) is used, whereas computer store
+# (Computer account) is used when running wpasvc as a service.
+# Alternatively, a named configuration blob can be used by setting this
+# to blob://<blob name>.
+# private_key_passwd: Password for private key file (if left out, this will be
+# asked through control interface)
+# dh_file: File path to DH/DSA parameters file (in PEM format)
+# This is an optional configuration file for setting parameters for an
+# ephemeral DH key exchange. In most cases, the default RSA
+# authentication does not use this configuration. However, it is possible
+# setup RSA to use ephemeral DH key exchange. In addition, ciphers with
+# DSA keys always use ephemeral DH keys. This can be used to achieve
+# forward secrecy. If the file is in DSA parameters format, it will be
+# automatically converted into DH params.
+# subject_match: Substring to be matched against the subject of the
+# authentication server certificate. If this string is set, the server
+# sertificate is only accepted if it contains this string in the subject.
+# The subject string is in following format:
+# /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
+# altsubject_match: Semicolon separated string of entries to be matched against
+# the alternative subject name of the authentication server certificate.
+# If this string is set, the server sertificate is only accepted if it
+# contains one of the entries in an alternative subject name extension.
+# altSubjectName string is in following format: TYPE:VALUE
+# Example: EMAIL:server@example.com
+# Example: DNS:server.example.com;DNS:server2.example.com
+# Following types are supported: EMAIL, DNS, URI
+# phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
+# (string with field-value pairs, e.g., "peapver=0" or
+# "peapver=1 peaplabel=1")
+# 'peapver' can be used to force which PEAP version (0 or 1) is used.
+# 'peaplabel=1' can be used to force new label, "client PEAP encryption",
+# to be used during key derivation when PEAPv1 or newer. Most existing
+# PEAPv1 implementation seem to be using the old label, "client EAP
+# encryption", and wpa_supplicant is now using that as the default value.
+# Some servers, e.g., Radiator, may require peaplabel=1 configuration to
+# interoperate with PEAPv1; see eap_testing.txt for more details.
+# 'peap_outer_success=0' can be used to terminate PEAP authentication on
+# tunneled EAP-Success. This is required with some RADIUS servers that
+# implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
+# Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
+# include_tls_length=1 can be used to force wpa_supplicant to include
+# TLS Message Length field in all TLS messages even if they are not
+# fragmented.
+# sim_min_num_chal=3 can be used to configure EAP-SIM to require three
+# challenges (by default, it accepts 2 or 3)
+# phase2: Phase2 (inner authentication with TLS tunnel) parameters
+# (string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
+# "autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS)
+# Following certificate/private key fields are used in inner Phase2
+# authentication when using EAP-TTLS or EAP-PEAP.
+# ca_cert2: File path to CA certificate file. This file can have one or more
+# trusted CA certificates. If ca_cert2 and ca_path2 are not included,
+# server certificate will not be verified. This is insecure and a trusted
+# CA certificate should always be configured.
+# ca_path2: Directory path for CA certificate files (PEM)
+# client_cert2: File path to client certificate file
+# private_key2: File path to client private key file
+# private_key2_passwd: Password for private key file
+# dh_file2: File path to DH/DSA parameters file (in PEM format)
+# subject_match2: Substring to be matched against the subject of the
+# authentication server certificate.
+# altsubject_match2: Substring to be matched against the alternative subject
+# name of the authentication server certificate.
+#
+# fragment_size: Maximum EAP fragment size in bytes (default 1398).
+# This value limits the fragment size for EAP methods that support
+# fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set
+# small enough to make the EAP messages fit in MTU of the network
+# interface used for EAPOL. The default value is suitable for most

+# nai: user NAI (ID_Client)
+#
+# EAP-FAST variables:
+# pac_file: File path for the PAC entries. wpa_supplicant will need to be able
+# to create this file and write updates to it when PAC is being
+# provisioned or refreshed. Full path to the file should be used since
+# working directory may change when wpa_supplicant is run in the
+# background. Alternatively, a named configuration blob can be used by
+# setting this to blob://<blob name>
+# phase1: fast_provisioning=1 option enables in-line provisioning of EAP-FAST

+#
+# wpa_supplicant supports number of "EAP workarounds" to work around
