-
-mbind.2
- Michael Kerrisk [Daniel J Blueman]
- Clarify EFAULT text
+fflush.3
+ Michael Kerrisk [Sergey V. Zubkov]
+ Clarify that flushing of input streams occurs only for seekable files
+ See https://bugzilla.kernel.org/show_bug.cgi?id=91931
+ Michael Kerrisk [Sergey V. Zubkov]

-perf_event_open.2
- Vince Weaver
- Clarify description of overflow events
- 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
+termios.3
Michael Kerrisk
- Add some kernel version numbers to various fields and constants

-ptrace.2
-sigaction.2
-seccomp.2
- Kees Cook
- Ptrace and siginfo details
- While writing some additional seccomp tests, I realized
- PTRACE_EVENT_SECCOMP wasn't documented yet. Fixed this, and added
- additional notes related to ptrace events SIGTRAP details.
+tzset.3
+ J William Piggott
+ Document behavior when TZ filespec omits the colon
+ If the TZ filespec omits the leading colon, glibc will parse
+ it for any valid format, i.e., it will still work.
+ 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.
-readv.2
- Michael Kerrisk
- Update details on glibc readv()/writev() wrapper behavior
- And add a historical detail about Linux 2.0.
+ 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.
-select.2
- Michael Kerrisk
- Mention RLIMIT_NOFILE as a possible cause of EINVAL error
+ 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.

- Note kernel version that introduced create_module()
- Note kernel version that added setup()
- Michael Kerrisk

-
-utimensat.2
- Michael Kerrisk [Elliot Hughes]
- If both tv_sec fields are UTIME_OMIT, the file need not exist
- As noted by Elliot, if both tv_sec fields are UTIME_OMIT,
- utimensat() will return success even if the file does not exist.
+ SEE ALSO: add chfn(1), chsh(1)
-errno.3
+capabilities.7
Michael Kerrisk

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

- Michael Kerrisk
- Rewrite the script+close-on-exec problem as a BUG
