+ Mention default path for compiled files
+
+clock_nanosleep.2

+
+epoll_ctl.2
+ Michael Kerrisk
+ Regular files and directories can't be monitored with epoll_ctl()
+
+ioctl.2
+ Heinrich Schuchardt
+ Rename 'd' argument to 'fd' in text
+ In most other manpages file descriptors are called 'fd'.
+ This patches renames attribute 'd' to 'fd'.
+
+madvise.2
+ Michael Kerrisk
+ VERSIONS: Support for madvise() is now configurable
+ Support for this system call now depends on the
+ CONFIG_ADVISE_SYSCALLS configuration option.
+
+open.2
+ Michael Kerrisk
+ Enhance rationale discussion for openat() and friends
+
+posix_fadvise.2
+ Mel Gorman
+ Document the behavior of partial page discard requests
+ It is not obvious from the interface that "partial page discard"
+ requests are ignored. It should be spelled out.
+ Michael Kerrisk [Weijie Yang]
+ ERRORS: Since 2.6.16, the kernel correctly deals with the ESPIPE case
+ Michael Kerrisk
+ Support for fadvise64() is now configurable
+ Support for this system call now depends on the
+ CONFIG_ADVISE_SYSCALLS configuration option.
+
+prctl.2
+ Andreas Schwab
+ Correct description of null-termination in PR_GET_NAME and PR_SET_NAME
+ The size of the process name has always been at most 16 byte
+ _including_ the null terminator. This also means that the
+ name returned by PR_GET_NAME is always null-terminated.
+ Michael Kerrisk
+ PR_SET_NAME silently truncates strings that exceed 16 bytes
+
+restart_syscall.2
+ Michael Kerrisk
+ Add some text explaining why restart_syscall() exists
+
+sched_setaffinity.2
+ Michael Kerrisk
+ NOTES: Add paragraph on how to discover set of CPUs available on system

+
+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

+ Add some detail on the sa_restorer field
+ Michael Kerrisk

+
+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.

+ [4] https://sourceware.org/bugzilla/show_bug.cgi?id=12734
+
+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.

+
+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.

+ 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

+fclose.3
+ Carlos O'Donell
+ Consistency fix: use "stream" as name for "FILE *" argument

+ instead of randomly using "fp" or "stream." Choosing something
+ and being consistent helps users scan the man pages quickly
+ and understand what they are looking at.
+
+fexecve.3
