Apologies if I missed anyone!
-Newly documented interfaces in existing pages
----------------------------------------------
+New and rewritten pages
+-----------------------
-perf_event_open.2
- Vince Weaver
- Add PERF_IOC_FLAG_GROUP documentation
- The perf_event_open() ENABLE/DISABLE/RESET ioctls can take an
- argument, PERF_IOC_FLAG_GROUP. This wasn't documented at all
- until about a year ago (despite the support being there from
- the beginning) so I missed this when initially writing
- the man page.
+getrandom.2
+ Heinrich Schuchardt, Theodore T'so, Michael Kerrisk
+ New page documenting getrandom(2)
+ Kernel 3.17 introduces a new system call getrandom(2).
-socket.7
- Pavel Emelyanov, Michael Kerrisk
- Document SO_PEEK_OFF option
- Since Linux 3.4 there appeared an ability to specify the
- offset in bytes from which the data will be MSG_PEEK-ed.
- Describe this socket option in the socket(7) page, where
- all the other socket options are described.
+kexec_load.2
+ Vivek Goyal, Michael Kerrisk
+ Add documentation of kexec_file_load(2)
+ Michael Kerrisk, Vivke Goyal
+ Rewrite and extend documentation of kexec_load().
-Global changes
---------------
+New and changed links
+---------------------
-Various pages
+kexec_file_load.2
Michael Kerrisk
- Convert inline formatting (\fX...\fP) to dot-directive formatting
-
-readdir.2
-asprintf.
-getline.3
-getlogin.3
-pthread_setname_np.3
-readdir.3
-strerror.3
- Michael Kerrisk [Jon Grant]
- Clarify that terminating null byte is '\0'
-
+ New link to kexec_load.2
Changes to individual pages
---------------------------
-execve.2
- Peter LaDow
- Add envp to the Linux notes about NULL pointers
- During the review of static analysis results, we discovered a
- functional, but non-portable, use of execve(). For example:
-
- char *cmd[] = { "/path/to/some/file", NULL };
- execve(cmd[0], cmd, NULL);
-
- The call succeeds. Yet, the static analysis tool (rightly)
- pointed out that envp could be dereferenced. But digging into
- glibc and the kernel, it appears that like argv, envp when NULL
- is treated as if it were an empty list.
-
- So, to clear things up, I'm submitting this patch to update the
- man page to indicate that envp is treated like argv.
-
-fallocate.2
+personality.2
Michael Kerrisk
- RETURN VALUE: mention that 'errno' is set on error
-
-io_setup.2
- Cyril Hrubis [Jeff Moyer]
- Clarify the nr_events parameter
- Currently the io_setup.2 man page describes what the kernel really
- does, i.e., that the resulting context may be able to hold more
- than the 'nr_event's operations because the memory allocated in
- kernel is rounded to be multiple of page size.
-
- It is better not to expose this implementation detail and
- simply state that the resulting context is suitable for
- 'nr_events' operations.
-
-perf_event_open.2
- Vince Weaver
- Clarify the perf_event_open() wakeup_events/wakeup_watermark fields
- Clarify the perf_event_open() wakeup_events/wakeup_watermark
- fields a bit, based on info from kernel commit cfeb1d90a1b1.
- Vince Weaver
- Update to match the Linux 3.10 release
- This patch updates the perf_event_open() documentation to include
- new interfaces added in the 3.10 kernel.
-
- It also documents a few [To be documented] instances left over
- from the 3.7 kernel.
- Vince Weaver
- Small correction to description of 'flags' argument
+ SEE ALSO: add setarch(8)
prctl.2

+tzset.3

+ J William Piggott
+ Add description for posixrules file
+ J William Piggott
+ Correct system timezone file path
+ J William Piggott
+ There are only two TZ formats
+ tzset(3) currently states that there are three TZ formats. The
+ first two it lists are actually variations of the POSIX-style
+ TZ format, of which there are at least five variations.
+
+ This patch corrects this to match the POSIX specification of
+ TZ having only two formats.
+ J William Piggott
+ Filespec omitted incorrect
+ Paragraph three of the DESCRIPTION section says
+ that when TZ is set, but empty, then UTC is used.
+
+ Later it says if the TZ filespec is omitted then the file
+ /usr/share/zoneinfo/localtime is used. This is incorrect,
+ it will use UTC in that case as well.
+ J William Piggott
+ Fix incorrect TZ string representation
+ The TZ string representation indicates that the start/end
+ rules are required; this is incorrect.
+ J William Piggott
+ Add ENVIRONMENT section + other rearrangements
+ FILES section was overly verbose and included
+ environment variables. Added ENVIRONMENT section,
+ removing ENV VARS from the FILES section.
