ChangeLog for hostapd
+????-??-?? - v2.1
+ * added support for simulataneous authentication of equals (SAE) for
+ stronger password-based authentication with WPA2-Personal
+
+2013-01-12 - v2.0
+ * added AP-STA-DISCONNECTED ctrl_iface event
+ * improved debug logging (human readable event names, interface name
+ included in more entries)
+ * added number of small changes to make it easier for static analyzers
+ to understand the implementation
+ * added a workaround for Windows 7 Michael MIC failure reporting and
+ use of the Secure bit in EAPOL-Key msg 3/4
+ * fixed number of small bugs (see git logs for more details)
+ * changed OpenSSL to read full certificate chain from server_cert file
+ * nl80211: number of updates to use new cfg80211/nl80211 functionality
+ - replace monitor interface with nl80211 commands
+ - additional information for driver-based AP SME
+ * EAP-pwd:
+ - fix KDF for group 21 and zero-padding

+ * added support for libnl 3.2 and newer
+ * increased initial group key handshake retransmit timeout to 500 ms
+ * added a workaround for 4-way handshake to update SNonce even after
+ having sent EAPOL-Key 3/4 to avoid issues with some supplicant
+ implementations that can change SNonce for each EAP-Key 2/4
+ * added a workaround for EAPOL-Key 4/4 using incorrect type value in
+ WPA2 mode (some deployed stations use WPA type in that message)
+ * added a WPS workaround for mixed mode AP Settings with Windows 7
+ * changed WPS AP PIN disabling mechanism to disable the PIN after 10

+ * EAP-AKA: added support for AT_COUNTER_TOO_SMALL
+ * EAP-AKA: skip AKA/Identity exchange if EAP identity is recognized
+ * EAP-AKA': fixed identity for MK derivation
+ * EAP-AKA': updated to RFC 5448 (username prefixes changed); note: this
+ breaks interoperability with older versions
+ * EAP-SIM/AKA: allow pseudonym to be used after unknown reauth id
+ * changed ANonce to be a random number instead of Counter-based
+ * added support for canceling WPS operations with hostapd_cli wps_cancel
+ * fixed EAP/WPS to PSK transition on reassociation in cases where
+ deauthentication is missed
+ * hlr_auc_gw enhancements:
+ - a new command line parameter -u can be used to enable updating of
+ SQN in Milenage file
+ - use 5 bit IND for SQN updates
+ - SQLite database can now be used to store Milenage information
+ * EAP-SIM/AKA DB: added optional use of SQLite database for pseudonyms
+ and reauth data
+ * added support for Chargeable-User-Identity (RFC 4372)

+ * added support for 256-bit AES with internal TLS implementation
+ * changed EAPOL transmission to use AC_VO if WMM is active
+ * fixed EAP-TLS/PEAP/TTLS/FAST server to validate TLS Message Length
+ correctly; invalid messages could have caused the hostapd process to
+ terminate before this fix [CVE-2012-4445]
+ * limit number of active wildcard PINs for WPS Registrar to one to avoid
+ confusing behavior with multiple wildcard PINs
+ * added a workaround for WPS PBC session overlap detection to avoid
+ interop issues with deployed station implementations that do not
+ remove active PBC indication from Probe Request frames properly
+ * added support for using SQLite for the eap_user database
+ * added Acct-Session-Id attribute into Access-Request messages
+ * fixed EAPOL frame transmission to non-QoS STAs with nl80211
+ (do not send QoS frames if the STA did not negotiate use of QoS for
+ this association)
+
+2012-05-10 - v1.0
+ * Add channel selection support in hostapd. See hostapd.conf.
+ * Add support for IEEE 802.11v Time Advertisement mechanism with UTC
+ TSF offset. See hostapd.conf for config info.
+ * Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
+ This allows the driver to use PS buffering of Deauthentication and
+ Disassociation frames when the STA is in power save sleep. Only
+ available with drivers that provide TX status events for Deauth/
+ Disassoc frames (nl80211).
+ * Allow PMKSA caching to be disabled on the Authenticator. See
+ hostap.conf config parameter disable_pmksa_caching.
+ * atheros: Add support for IEEE 802.11w configuration.
+ * bsd: Add support for setting HT values in IFM_MMASK.
+ * Allow client isolation to be configured with ap_isolate. Client
+ isolation can be used to prevent low-level bridging of frames
+ between associated stations in the BSS. By default, this bridging
+ is allowed.
+ * Allow coexistance of HT BSSes with WEP/TKIP BSSes.
+ * Add require_ht config parameter, which can be used to configure
+ hostapd to reject association with any station that does not support
+ HT PHY.
+ * Add support for writing debug log to a file using "-f" option. Also
+ add relog CLI command to re-open the log file.
+ * Add bridge handling for WDS STA interfaces. By default they are
+ added to the configured bridge of the AP interface (if present),
+ but the user can also specify a separate bridge using cli command
+ wds_bridge.
+ * hostapd_cli:
+ - Add wds_bridge command for specifying bridge for WDS STA
+ interfaces.
+ - Add relog command for reopening log file.
+ - Send AP-STA-DISCONNECTED event when an AP disconnects a station
+ due to inactivity.
+ - Add wps_config ctrl_interface command for configuring AP. This
+ command can be used to configure the AP using the internal WPS
+ registrar. It works in the same way as new AP settings received
+ from an ER.
+ - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
+ - Add command get version, that returns hostapd version string.
+ * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
+ Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
+ notification to the STA.
+ * Allow AP mode to disconnect STAs based on low ACK condition (when
+ the data connection is not working properly, e.g., due to the STA
+ going outside the range of the AP). Disabled by default, enable by
+ config option disassoc_low_ack.
+ * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
+ config file.
+ * WPS:
+ - Send AP Settings as a wrapped Credential attribute to ctrl_iface
+ in WPS-NEW-AP-SETTINGS.
+ - Dispatch more WPS events through hostapd ctrl_iface.
+ - Add mechanism for indicating non-standard WPS errors.
+ - Change concurrent radio AP to use only one WPS UPnP instance.
+ - Add wps_check_pin command for processing PIN from user input.
+ UIs can use this command to process a PIN entered by a user and to
+ validate the checksum digit (if present).
+ - Add hostap_cli get_config command to display current AP config.
+ - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
+ runtime and support dynamic AP PIN management.
+ - Disable AP PIN after 10 consecutive failures. Slow down attacks
+ on failures up to 10.
+ - Allow AP to start in Enrollee mode without AP PIN for probing,
+ to be compatible with Windows 7.
+ - Add Config Error into WPS-FAIL events to provide more info
+ to the user on how to resolve the issue.
+ - When controlling multiple interfaces:
+ - apply WPS commands to all interfaces configured to use WPS
+ - apply WPS config changes to all interfaces that use WPS
+ - when an attack is detected on any interface, disable AP PIN on
+ all interfaces
+ * WPS ER:
+ - Show SetSelectedRegistrar events as ctrl_iface events.
+ - Add special AP Setup Locked mode to allow read only ER.
+ ap_setup_locked=2 can now be used to enable a special mode where
+ WPS ER can learn the current AP settings, but cannot change them.
+ * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
+ - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
+ for testing protocol extensibility.
+ - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
+ workarounds.
+ - Add support for AuthorizedMACs attribute.
+ * TDLS:
+ - Allow TDLS use or TDLS channel switching in the BSS to be
+ prohibited in the BSS, using config params tdls_prohibit and
+ tdls_prohibit_chan_switch.
+ * EAP server: Add support for configuring fragment size (see
+ fragment_size in hostapd.conf).
+ * wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
+ wlantest can be used to capture frames from a monitor interface
+ for realtime capturing or from pcap files for offline analysis.
+ * Interworking: Support added for 802.11u. Enable in .config with
+ CONFIG_INTERWORKING. See hostapd.conf for config parameters for
+ interworking.
+ * Android: Add build and runtime support for Android hostapd.
+ * Add a new debug message level for excessive information. Use
+ -ddd to enable.
+ * TLS: Add support for tls_disable_time_checks=1 in client mode.
+ * Internal TLS:
+ - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
+ CONFIG_TLSV11.
+ - Add domainComponent parser for X.509 names
+ * Reorder some IEs to get closer to IEEE 802.11 standard. Move
+ WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
+ Move HT IEs to be later in (Re)Assoc Resp.
+ * Many bugfixes.
+
2010-04-18 - v0.7.2
