+
+ [1] https://sourceware.org/bugzilla/show_bug.cgi?id=16975
+

+ Fix prototype for set_mempolicy(2)
+ The nodemask argument is const. The return type in numaif.h is long.
+
+swapon.2
+ Rasmus Villemoes
+ Remove header from synopsis
+ The <asm/page.h> header is not readily available, and the comment
+ seems to indicate that it is for getting PAGE_SIZE. But it is
+ never mentioned why one would need to know that, and it is in any
+ case better obtained using sysconf(), provided by <unistd.h>.
+
+a64l.3
+ Rasmus Villemoes
+ Fix prototype for a64l()
+ The argument is const, both according to POSIX and the
+ glibc headers.

+
+getrpcport.3

+ Fix prototypes
+ Remove const qualifiers from arguments to key_decryptsession,
+ key_encryptsession, and key_setsecret.
+
+makecontext.3
+ Rasmus Villemoes
+ Fix prototype
+ The second argument to swapcontext() is const.
+
+makedev.3
+ Rasmus Villemoes
+ Fix prototype
+ gnu_dev_makedev, and hence its trivial macro wrapper makedev, takes
+ two unsigned int parameters; this is consistent with it being the
+ inverse of (gnu_dev_)major/minor, which return unsigned int.
+
+malloc_trim.3
+ Rasmus Villemoes
+ Fix prototype
+ As mentioned further down, malloc_trim returns an integer.
+

+ Add feature test macro requirements
+

+ Add missing #include <signal.h>
+
+rcmd.3
+ Rasmus Villemoes

+ Unlike the BSDs, the second argument of rcmd() and rcmd_af() has
+ type unsigned short.
+ The first argument of iruserok_af() has type const void*.
+
+re_comp.3
+ Rasmus Villemoes
+ Fix prototypes
+ re_comp and re_exec take const char* arguments.
+
+resolver.3
+ Rasmus Villemoes
+ Fix prototypes and extern-declaration
+ Fix const- and signedness of various char* parameters.
+
+ Also, there is no "struct state", but _res is a struct
+ __res_state. (Actually, _res is errno-like in that it is really a
+ macro expanding to (*__res_state()).)
+
+rexec.3
+ Rasmus Villemoes
+ Fix prototypes
+ The user, passwd and cmd arguments to rexec and rexec_af are all
+ const.
+
+rtime.3
+ Rasmus Villemoes

+
+scandir.3
+ Rasmus Villemoes

+
+core.5

+ Michael Kerrisk [Marko Myllynen]
+ Add brief descriptions of collating-element and collating-symbol
+ Marko Myllynen
+ t_fmt_ampm is needed only for locales that employ AM/PM convention
+ Michael Kerrisk [Marko Myllynen]
+ Remove crufty reference to /usr/lib/nls/src
+ That file is nowhere to be found
+ Marko Myllynen
+ Clarify LC_TIME/am_pm and LC_NAME keywords usage
+ am_pm should be defined only if AM/PM convention is used to signal
+ applications they should not try to print them when using them in
+ unwanted.
+
+ Same for all LC_NAME keywords expect for name_fmt which should be
+ always defined.
+ Marko Myllynen
+ Clarify lang_term / lang_lib
+ As noted by Keld Simonsen in the lib-locales@sourceware mailing
+ list:
+
+ https://sourceware.org/ml/libc-locales/2014-q2/msg00008.html
+ From: Keld Simonsen <keld at rap dot rap dot dk>
+ To: Marko Myllynen <myllynen at redhat dot com>
+ Date: Tue, 29 Apr 2014 17:02:09 +0200
+
+ lang_term reflects ISO 639-2/T (terminology) codes, while
+ lang_lib reflects ISO 639-2/B (bibliographic) codes.
+ lang_term is preferred over lang_lib codes for locale names.
+ There are 20 specific ISO 639-2/B codes.
+ Marko Myllynen
+ Correct the FILES section
+
+proc.5
+ Michael Kerrisk
+ 'pid_max' is a system-wide limit on number of threads and processes
+ Since PIDs > /proc/sys/kernel/pid_max are not allocated, this
+ file thus also imposes a system-wide limit on the number of
+ threads and processes.
+
+capabilities.7
+ Michael Kerrisk
+ CAP_SYS_ADMIN allows overriding RLIMIT_NPROC
+ Michael Kerrisk
+ CAP_SYS_PTRACE allows process_vm_readv(2) and process_vm_writev(2)
+
+charsets.7
+ Michael Kerrisk [Marko Myllynen]
+ Remove crufty statement that Romanian may be switching to ISO 8859-16
+ Michael Kerrisk
+ Remove ancient paragraph on charsets supported in glibc 2.3.2
+ That test is rather ancient, and probably of little use.
+
+fanotify.7
+ Heinrich Schuchardt
+ Fix to example program: fanotify read() should use aligned buffer
+
+inotify.7
+ Heinrich Schuchardt
+ Add example program
+ This example of the usage of the inotify API shows the
+ usage of inotify_init1(2) and inotify_add_watch(2) as well
+ as polling and reading from the inotify file descriptor.
+ Heinrich Schuchardt
+ munmap() does not generate inotify events
+
+locale.7
+ Marko Myllynen [Michael Kerrisk]
+ Document the LOCPATH environment variable
+ Michael Kerrisk
+ Add further details on various categories

+
+syscalls.2
+ Carlos O'Donell
+ Add prlimit64(2)
+ While trying to reconcile the new features in glibc with the
+ documented entries in the linux kernel man pages I noticed that
+ glibc exports prlimit64 for use by 32-bit applications (as does
+ the linux kernel), but that prlimit64 was not defined in the
+ syscalls list or in the prlimit-related page.
+
+ This is not the complete fix for this, but I don't have the time
+ to explain why and when prlimit64 should be used (or how it should
+ be used safely). Therefore I'm just patching the syscalls.2 list
+ to show that prlimit64 exists and was added in 2.6.36 (verified
+ with git by checking out the tags before and after).
+
+syslog.2
+ Michael Kerrisk
+ Rework introductory paragraph
+ Michael Kerrisk [Robert P. J. Day]
+ Rework text describing loglevels
+ The kernel header file mentioned in the discussion of the KERN_*
+ constants has morphed and is no longer exported inside glibc.
+ And the definitions of the constants themselves changed subtly
+ with kernel commit 04d2c8c83d0e3ac5f78aeede51babb3236200112.
+ So, rewrite the description of the constants to be a bit more
+ abstract.
+ Michael Kerrisk
+ Rewrite parts of the page, and import /proc/sys/kernel/printk
+ * Move /proc/sys/kernel/printk from proc(5) to this page,
+ and correct various details in the discussion of that file.
+ * Rewrite and correct various other details on the page.
+ * Clean out some crufty text.
+ * Miscellaneous minor fixes.
+ Michael Kerrisk
+ Update SYSLOG_ACTION_CONSOLE_OFF + SYSLOG_ACTION_CONSOLE_ON description
+ Details changed in Linux 2.6.32
+
+tee.2
+ Michael Kerrisk
+ Document EAGAIN error
+ See https://bugzilla.kernel.org/show_bug.cgi?id=48641
+
+vmsplice.2
+ Michael Kerrisk
+ Document EAGAIN error
+ See https://bugzilla.kernel.org/show_bug.cgi?id=48641
+
+ether_aton.3
+ Michael Kerrisk
+ Make description of ether_line() bug a little more informative
+
+mallopt.3
+ Michael Kerrisk [Florian Weimer]
+ MALLOC_MMAP_THRESHOLD_ and MALLOC_MMAP_MAX_ *do* work in setgid programs
+ My testing on this point was bogus, overlooking details of
+ strace(1)'s behavior with setuid programs.
+
+ See https://sourceware.org/bugzilla/show_bug.cgi?id=12155
+
+printf.3
+ Michael Kerrisk [Rich Felker]
+ Remove libc4 and libc5 details
+ Rich Felker noted that "scare text" in the man page warned about
+ the use of snprintf() on libc, and that some people had cited
+ this as a reason not to use snprintf(). Linux libc is now
+ ancient history, so there is no real need to keep that text.
+ But, while we're at it, we may as well clear out all of the
+ other ancient libc4 and libc5 pieces in the page. They are
+ nowadays more clutter than help.
+ Michael Kerrisk
+ SUSv3 and later agree with C99 for the snprintf() return value
+ Determined by inspection of the SUSv3 and SUSv4 specifications.
+ Michael Kerrisk
+ Remove some old text about glibc 2.0 changes
+ We probably don't now need such ancient info.
+ Michael Kerrisk
+ Update references to standards for C and S conversion specifiers
+
+profil.3
+ Michael Kerrisk
+ SEE ALSO: add sprof(1)
+
+charmap.5
+ Marko Myllynen
+ Various minor updates and improvements
+ - more precise title
+ - extend description a bit
+ - document previously omitted WIDTH_DEFAULT
+ Marko Myllynen
+ Remove accidental ISO C compliance reference
+ glibc refers in locale/programs/charmap.c to ISO C 99 section
+ 7.17.(2) and ISO C 99 section 5.2.1.(3) that if a character map
+ is not ASCII compatible then the locale using it is not ISO C
+ compliant. This does not state anything about the character set
+ itself.
+
+proc.5
+ Michael Kerrisk
+ Replace /proc/sys/kernel/printk discussion with reference to syslog(2)
+ It makes more sense to have the /proc/sys/kernel/printk with
+ the related material in syslog(2).
+ Michael Kerrisk
+ Rewrite /proc/sys/kernel/printk description
+
+inotify.7
+ Michael Kerrisk
+ Clarify which events are generated for watched directories
+ Really, with respect to watched directories, events fall into
+ three classes (not two, as was shown):
+
+ * Events that can be generated only for the watched directory.
+ * Events that can be generated only for objects that are inside
+ the watched directory.
+ * Events that can be generated both for the watched directory
+ and for objects inside the directory.
+
+ So, mark these three classes more clearly in the list of inotify
+ events.
+ Heinrich Schuchardt [Michael Kerrisk]
+ BUGS: Note possible bug triggered by watch descriptor reuse
+ Watch descriptor IDs are returned by inotify_add_watch().
+ When calling inotify_rm_watch() an IN_IGNORED is placed on the
+ inotify queue pointing to the ID of the removed watch.
+
+ inotify_add_watch() should not return a watch descriptor ID for
+ which events are still on the queue but should return an
+ unused ID.
+
+ Unfortunately, the existing Kernel code does not provide such a
+ guarantee.
+
+ Actually, in rare cases watch descriptor IDs are returned by
+ inotify_add_watch() for which events are still on the inotify
+ queue.
+
+ See https://bugzilla.kernel.org/show_bug.cgi?id=77111
+ Michael Kerrisk
+ Add further detail to the watch descriptor reuse bug
+ As well as inotify_rm_watch(), file deletion and unmounting a
+ filesystem can also cause a watch descriptor to be deleted.
+ Michael Kerrisk
+ The watch descriptor reuse bug may be hard to hit in practice
+ Explain the circumstances in detail, indicating that the
+ bug may be very unlikely to occur in practice.
+ Michael Kerrisk
+ Clarify description of IN_EXCL_UNLINK
+ Clarify the text a little, in particular making it clearer
+ that the target of a watch is an i-node (not a pathname).
+ Michael Kerrisk
+ Clarify IN_ONESHOT explanation
+ Make it clearer that the target of monitoring is an i-node,
+ not a pathname.
+ Michael Kerrisk
+ Make comment on 'mask' field more accurate
+
+libc.7
+ Michael Kerrisk
+ Clarify man-pages policy on documenting C libraries other tahn glibc
+ Michael Kerrisk
+ Use absolute dates in discussion of libc vs glibc
+
+pipe.7
+ Elie De Brauwer
+ Add reference that the pipe capacity can be changed
+ In fcntl(2) F_SETPIPE_SZ, F_GETPIPE_SZ and
+ /proc/sys/fs/pipe-max-size are defined, however
+ pipe(7) still defines the pipe capacity as being
+ a static entity. Adding a reference to fcntl(2).
+ Michael Kerrisk [Walter Harms]
+ Clarify that since 2.6.35, 65535 bytes is the default pipe capacity
+
+ld.so.8
+ Michael Kerrisk
+ Clarify that LD_PROFILE can specify just a single shared object
+ Michael Kerrisk
+ Clarify that LD_PROFILE output is appended to target file
+ The LD_PROFILE output is appended to any existing
+ contents of the target file.
+ Michael Kerrisk

+sync.2
+proc.5
+ Adrian Bunk
+ Change "sync(1)" to "sync(8)"
+
+bind.2
+ Michael Kerrisk [Ryan Hammonds]
+ Correct EINVAL error description
+ As pointed out by Ryan:
+
+ My application is trying to bind an IPv4 UDP socket to an
+ address. I've found that passing an invalid address length
+ to bind() causes bind to return EINVAL. According to the
+ bind(2) manpage, this should only occur when using unix
+ domain sockets (which I am not).
+
+chmod.2
+ Michael Kerrisk
+ Glibc falls back to chmod() on kernels that don't support fchmodat()
+ Michael Kerrisk
+ Glibc falls back to chown()/lchown() on kernels that lack fchownat()
+
+epoll_wait.2
+ Michael Kerrisk
+ NOTES: describe raw epoll_pwait() system call differences

+
+perf_event_open.2
+ Vince Weaver
+ Clarify PERF_SAMPLE_STACK_USER usage
+ This clarifies the PERF_SAMPLE_STACK_USER section.
+ I found these issue while implementing some code that uses
+ the option. The important change is fixing the name of the
+ sample_stack_user parameter, the rest is just some wording
+ fixes and minor clarifications.
+ Vince Weaver
+ Clarify PERF_SAMPLE_DATA_SRC usage
+ When checking the fields in the PERF_SAMPLE_DATA_SRC type samples
+ you need to shift the masks before doing the compare.
+
+ Although the value you are checking (perf_mem_data_src) is
+ specified as a bitfield so this might all fall apart if trying
+ to access the field in a cross-endian way. The Power people
+ were working on this issue, not sure if they resolved it.

+ Peter Schiffer [Jan Chaloupka, Michael Kerrisk]
+ New page for glibc memusagestat(1) command

+ Peter Schiffer [Jan Chaloupka]
+ New page describing the glibc mtrace(1) command

+
+Changes to individual pages
+---------------------------
+
+connect.2
+ Michael Haardt
+ Note that a new socket should be used if connect() fails
+
+fcntl.2
+ Michael Kerrisk
+ One must define _GNU_SOURCE to get the F_OFD_* definitions
+
+poll.2, select.2
+ Rusty Russell
+ Fix erroneous description of "available for write".
+ POSIX says: "POLLOUT Normal data may be written without
+ blocking.". This "may" is misleading, see the POSIX
+ write page:
+
+ Write requests to a pipe or FIFO shall be handled in the
+ same way as a regular file with the following exceptions:
+ ...
+ If the O_NONBLOCK flag is clear, a write request may cause
+ the thread to block, but on normal completion it shall
+ return nbyte.
+ ...
+ When attempting to write to a file descriptor (other than a
+ pipe or FIFO) that supports non-blocking writes and cannot
+ accept the data immediately:
+
+ If the O_NONBLOCK flag is clear, write() shall block the
+ calling thread until the data can be accepted.
+
+ If the O_NONBLOCK flag is set, write() shall not block the
+ thread. If some data can be written without blocking the
+ thread, write() shall write what it can and return the
+ number of bytes written. Otherwise, it shall return -1 and
+ set errno to [EAGAIN].
+
+ The net result is that write() of more than 1 byte on a
+ socket, pipe or FIFO which is "ready" may block: write()
+ (unlike read!) will attempt to write the entire buffer and
+ only return a short write under exceptional circumstances.
+
+ Indeed, this is the behaviour we see in Linux:

+
+packet.7
+ Sorin Dumitru
+ Fix include file
+ It looks like most of the socket options from this man pages
+ are not defined in <netpacket/packet.h>. They are defined in
+ <linux/if_packet.h> so we should include that one.

+ Michael Kerrisk [J. Bruce Fields]
+ Don't mention "classical BSD" in discussion of fcntl()/flock interaction

+ be called from a process group leader
+
+sgetmask.2
+ Michael Kerrisk
+ Since 3.16, support for these system calls is configurable
+ Support for these calls is now dependent on the setting of the
+ CONFIG_SGETMASK_SYSCALL option.
+
+sigaction.2
+ Michael Kerrisk
+ Document SA_RESTORER
+ Michael Kerrisk
+ Add some detail on the sa_restorer field

+ Add bpf(2) to list
+
+tee.2
+ Michael Kerrisk
+ Add shell session demonstrating use of the example program
+
+tkill.2
+ Michael Kerrisk [Rich Felker]
+ Remove bogus text saying tgid==-1 makes tgkill() equivalent to tkill()
+
+abort.3
+ Michael Kerrisk
+ Note that SIGABRT is raised as though raise(3) is called
+ Also note that abort() is POSIX.1-2008 compliant.
+
+cmsg.3
+ David Wragg
+ Ensure buf is suitably aligned in sending example
+ Inspection of the definition of CMSG_FIRSTHDR (both in glibc and
+ the suggested definition in RFC3542) shows that it yields the
+ msg_control field. So when sending, the pointer placed in
+ msg_control should be suitably aligned as a struct cmsghdr.
+ In the sending example, buf was declared as a bare char array,
+ and so is not necessarily suitably aligned.
+
+ The solution here involves placing buf inside a union, and is
+ based on the sockets/scm_rights_send.c sample from The Linux
+ Programming Interface "dist" source code collection.
+
+exp10.3
+ Michael Kerrisk
+ Before glibc 2.19, exp() did not give ERANGE error on underflow
+ http://sources.redhat.com/bugzilla/show_bug.cgi?id=6787
+
+ftw.3
+ Michael Kerrisk
+ FTW_CHDIR has no effect on the 'fpath' argument passed to fn()
+
+getopt.3
+ Michael Kerrisk [Jonny Grant]
+ Ensure that 'nsecs' is used
+
+ilogb.3
+ Michael Kerrisk [Will Newton]
+ Since glibc 2.16, ilogb() does correctly diagnose domain errors
+
+memcmp.3
+ Michael Haardt
+ Document return value for n==0 case
+ Michael Haardt
+ Warn against use of memcmp() for comparing security-critical data
+
+mq_open.3
+ Michael Kerrisk
+ Document the O_CLOEXEC flag
+ Michael Kerrisk
+ Place 'flags' constants in alphabetical order
+
+pow.3
+ Manuel López-Ibáñez
+ Add note on performance characteristics of pow()
+
+pthread_setschedparam.3
+ Simon Newton
+ Fix logic error in example program
+ The example program will crash if -A is used, since 'attr'
+ is uninitialized.
+
+ $ ./a.out -A
+ *** Error in `./a.out': free(): invalid pointer: 0xb779c3c4 ***
+ Aborted (core dumped)
+ 刘湃
+ Small fixes to example program
+
+sigvec.3
+ Michael Kerrisk
+ Starting with version 2.21, glibc no longer exports sigvec()
+
+sysconf.3
+ Josh Triplett
+ Document _SC_NGROUPS_MAX
+ Already documented in getgroups(2), but not in sysconf(3).
+
+termios.3
+ Michael Kerrisk
+ SEE ALSO: add tset(1)
+
+tgamma.3
+ Michael Kerrisk
+ Since glibc 2.18, errno is correctly set to EDOM when (x == -infinity))
+
+wordexp.3
+ Carlos O'Donell
+ Make it clear that WRDE_NOCMD prevents command substitution
+ The use of WRDE_NOCMD prevents command substitution. If the flag
+ WRDE_NOCMD is set then no command substitution shall occur and
+ the error WRDE_CMDSUB will be returned if such substitution is
+ requested when processing the words.
+
+ The manual page as-is makes it seem like the command substitution
+ occurs, and an error is returned *after* the substitution.
+ This patch clarifies that.
+
+locale.5
+ Marko Myllynen
+ Describe the formats of values
+ locale(5) describes what a locale should define but doesn't
+ spell out how (in what format). The patch attempts to address
+ this, it also has few trivial additional enhancements.
+
+ * Reference to locale(7) for category descriptions.
+ * Clarify first_workday in NOTES a bit.
+ * Add upstream BZ reference for two missing LC_ADDRESS fields.
+ Marko Myllynen
+ Fix miscoded character
+
+resolv.conf.5
+ Jan Chaloupka
+ Add missing no-tld-query option
+ Based on commit [1], the no-tld-query option exists for
+ resolv.conf configuration file. Description of this option
+ is provided in [2]. This patch just copies this option
+ into resolv.conf.5 man page. Plus changes 'a' member
+ into 'an' before 'unqualified name as if it ...'
+ on the third line of [2]. Based on [3], this option
+ was added in glibc 2.14 as solving [4] bug.

+
+credentials.7
+ Josh Triplett
+ Cross-reference getgroups(2)
+ Since credentials.7 discusses supplementary GIDs, it should
+ reference getgroups(2).
+
+fanotify.7
+ Heinrich Schuchardt
+ Allow relative paths in example
+ The current example code requires passing an absolute
+ path to the mount to be watched.
+
+ By passing AT_FDCWD to fanotify_mark it can use both
+ absolute and relative paths.
+ Heinrich Schuchardt
+ fallocate(2) creates no events
+ fallocate(2) should create FAN_MODIFY events but does not.
+ Heinrich Schuchardt [Michael Kerrisk]
+ fanotify notifies only events generated on the same mount
+ Unfortunately, fanotify does not inform listeners for all paths
+ under which a touched filesystem object is visible, but only the
+ listener using the same path as the process touching the
+ filesystem object.
+ Heinrich Schuchardt
+ Update BUGS to note bugs still not fixed in 3.17
+ I bumped the Linux version number in the BUGS section to 3.17.
+
+inotify.7
+ Heinrich Schuchardt
+ fallocate(2) does not trigger inotify events
+ Calling fallocate(2) does not result in inotify events.
+
+locale.7
+ Marko Myllynen
+ Improve LOCPATH description
+ LOCPATH is ignored by privileged programs.
+
+ Add locale archive references.
+
+ Add FILES section.
+
+man-pages.7
+ Michael Kerrisk [Laurent Georget]
+ Clarify that SEE ALSO entries may refer to pages from other projects
+
+signal.7
+ Michael Kerrisk
+ Mention other "slow devices"
+ Reads from eventfd(2), signalfd(2), timerfd(2), inotify(7),
+ and fanotify(7) file descriptors are also slow operations
+ that are restartable.
+ Michael Kerrisk
+ Fix SO_RECVTIMEO/ SO_SENDTIMEO confusion in text
+ Michael Kerrisk
+ Since Linux 3.8, reads on inotify(7) file descriptors are restartable
+ Michael Kerrisk
+ inotify(7) reads no longer show the odd EINTR error after SIGCONT
+ Since kernel 3.7, reads from inotify(7) file descriptors no longer
+ show the (Linux oddity) behavior of failing with EINTR when the
+ process resumes after a stop signal + SIGCONT.
+ Michael Kerrisk
+ SEE ALSO: add sigreturn(2)
+
+unix.7
+ Michael Kerrisk [Scott Harvey]
+ Fix buglet in code snippet in BUGS section
+
+ld.so.8
+ Carlos O'Donell
+ Add --inhibit-cache option
+ The dynamic loader has 6 options, only 5 are documented.
+ This patch documents the sixth option i.e. `--inhibit-cache`.
+ Jonathan Wakely [Siddhesh Poyarekar]
+ Correct documentation of $ORIGIN
+ As noted by Siddhesh:
+
+ The ld.so man page says:
+
+ $ORIGIN (or equivalently ${ORIGIN})
+ This expands to the directory containing the
+ application executable. Thus, an application located
+ in somedir/app could be compiled with
+
+ This is incorrect since it expands to the directory containing
+ the DSO and not the application executable. This seems like
+ deliberate behaviour in dl-object.c, so it needs to be fixed in
+ the man page.
+
+ See http://stackoverflow.com/questions/26280738/what-is-the-equivalent-of-loader-path-for-rpath-specification-on-linux/26281226#26281226

+
+New and rewritten pages
+-----------------------
+
+seccomp.2
+ Kees Cook, Michael Kerrisk, Will Drewry [Andy Lutomirski]
+ New page documenting seccomp(2)
+ Combines documentation from prctl, in-kernel seccomp_filter.txt
+ and dropper.c, along with details specific to the new system call.
+
+
+Newly documented interfaces in existing pages
+---------------------------------------------
+
+netlink.7
+ Stephan Mueller [Michael Kerrisk]
+ Add NETLINK_CRYPTO
+
+
+Changes to individual pages
+---------------------------
+
+adjtimex.2
+ Laurent Georget [Richard Cochran, Jeff Epler]
+ Clarify the 'ppm scaling' used in struct timex
+ This patch makes explicit and clarifies the unit used for
+ the fields "freq", "ppsfreq" and "stabil" in struct timex.
+ Michael Kerrisk [Masanari Iida]
+ Note that TIME_ERROR is the modern synonym for TIME_BAD
+
+perf_event_open.2
+ Vince Weaver
+ Clarify the PERF_FLAG_FD_* flags
+ This change clarifies the behavior of the PERF_FLAG_FD_OUTPUT and
+ PERF_FLAG_FD_NO_GROUP flags to perf_event_open(), and removes
+ the related FIXME comments.
+
+ While writing tests to validate the behavior of these flags I
+ discovered that PERF_FLAG_FD_OUTPUT has been broken since the
+ 2.6.35 kernel release.
+
+prctl.2
+ Dave Hansen [Michael Kerrisk]
+ Add description of Intel MPX calls
+ The 3.19 kernel will have support for Intel MPX, including
+ a pair of new prctl() calls (PR_MPX_ENABLE_MANAGEMENT and
+ PR_MPX_DISABLE_MANAGEMENT) for enabling and disabling the
+ kernel's management of the "bounds tables". Add a
+ descriptions of the interface.
+ Michael Kerrisk
+ Add mention of seccomp(2) under PR_SET_SECCOMP
+ Michael Kerrisk
+ Suggest /proc/PID/status "Seccomp" as alternative to PRCTL_GET_SECCOMP
+ Michael Kerrisk
+ SIGKILL can also occur PRCTL_GET_SECCOMP in SECCOMP_MODE_FILTER mode
+ Kees Cook [Andy Lutomirski]
+ Document SECCOMP_MODE_FILTER vs EFAULT
+ This notes the distinction made between EINVAL and EFAULT when
+ attempting to use SECCOMP_MODE_FILTER with PR_SET_SECCOMP.
+
+setns.2
+pid_namespaces.7
+ Mike Frysinger
+ Elaborate discussion of the PID namespace descendant limitation
+ The setns(2) man page already mentions that CLONE_NEWPID may only
+ be used with descendant namespaces, but this nuance could be
+ listed in a few more places so it is not missed.
+
+shmget.2
+ Michael Kerrisk [Akihiro Motoki]
+ Make wording of SHMALL description a little clearer
+
+sigaction.2
+ Michael Kerrisk
+ Add siginfo_t fields for SECCOMP_RET_TRAP
+
+memchr.3
+strstr.3
+ Alexandre Bique
+ Reference memmem(3) in SEE ALSO section
+
+memcmp.3
+ Michael Kerrisk [Michael Haardt]
+ NOTES: add some detail on avoiding memcmp() of cryptographic data
+ Wording largely based on comments from Michael Haardt.
+
+pthread_tryjoin_np.3
+ Jérôme Pouiller [Michael Kerrisk]
+ Document EINVAL error for pthread_timedjoin_np()
+
+mem.4
+ Elie De Brauwer
+ /dev/kmem depends on CONFIG_DEVKMEM
+ Elie De Brauwer
+ Correct /dev/port group in example
+ mem.4 mentions that group for /dev/port should be set to 'mem'
+ However, all other files (/dev/mem and /dev/kmem) use the kmem
+ group in their examples and on my system /dev/port belongs to
+ kmem. Hence the 'mem' group was probably a typo:
+ Elie De Brauwer
+ Add CONFIG_STRICT_DEVMEM
+ Since 2.6.26 the CONFIG_NONPROMISC_DEVMEM options limits the
+ physical addresses which can be accessed through /dev/mem.
+
+random.4
+ Heinrich Schuchardt
+ Describe handling of O_NONBLOCK
+ /dev/random and /dev/urandom treat O_NONBLOCK differently.
+ This should be described in the manpage.
+ Heinrich Schuchardt
+ Mention PRNG used by urandom
+ /dev/urandom uses a pseudo-random number generator to replace
+ missing entropy.
+
+proc.5
+ Michael Kerrisk
+ Document "Seccomp" field of /proc/PID/status
+
+epoll.7
+ Michael Kerrisk [Ignat Loskutov]
+ Use epoll_create1() rather than epoll_create() in the code example
+ epoll_create1() is more or less the preferred API for new
+ applications, since it allows for some flags and avoids the
+ misdesigned epoll_create() argument, and so it seems sensible
+ to use that in the example, rather than epoll_create().
+
+tcp.7
+ Troy Davis
+ Clarify tcp_tw_recycle on Internet-facing hosts
+ Clarify that tcp_tw_recycle will break communication with many
+ general-purpose remote Internet hosts (namely, remote NAT devices)
+ even when the Linux device itself is not behind NAT.

+ Update the perf_event_open manpage to be more consistent when
+ discussing overflow events. It merges the discussion of
+ poll-type notifications with those generated by SIGIO
+ signal handlers.
+ This addresses the remaining FIXMEs is the document.
+ Vince Weaver
+ Remove inaccurate paragraph describing attr.config
+ Remove an inaccurate paragraph about values in the attr.config
+ field. This information was never true in any released kernel;
+ it somehow snuck into the manpage because it is still described
+ this way in tools/perf/design.txt in the kernel source tree.
+ Michael Kerrisk
+ Correct the kernel version number for PERF_COUNT_HW_CACHE_NODE
+ Michael Kerrisk
+ Add some kernel version numbers to various fields and constants

+ and being consistent helps users scan the man pages quickly
+ and understand what they are looking at.
+
+fexecve.3
