Global changes
--------------

assert.3
assert_perror.3
rexec.3
rpc.3
Michael Kerrisk [Jon Grant]
Reword a sentence to use more gender-neutral language


Changes to individual pages
---------------------------

execve.2
Michael Kerrisk
'arg...' for interpreter scripts starts with argv[1]

fallocate.2
Christoph Hellwig
Clarify the zeroing behavior
fallocate() zeroes only space that did not previously contain
data, but leaves existing data untouched.

futex.2
Rodrigo Campos
Fix link to Rusty's futex example library
When I asked to webmaster@kernel.org, Konstantin Ryabitsev
answered that the ".nl." is "an obsolete scheme and really
should be changed to just ftp.kernel.org".

getgroups.2
Michael Kerrisk
Note that NGROUPS_MAX is defined in
Michael Kerrisk
Clarify that sysconf(_SC_NGROUPS_MAX) is a run-time technique
Michael Kerrisk
Document /proc/sys/kernel/ngroups_max

ioctl.2
Michael Kerrisk [KOSAKI Motohiro, David Gibson]
'request' argument is typed as 'unsigned long' in glibc
See https://bugzilla.kernel.org/show_bug.cgi?id=42705

perf_event_open.2
Vince Weaver
Linux 3.12 rdpmc/mmap
It turns out that the perf_event mmap page rdpmc/time setting was
broken, dating back to the introduction of the feature. Due
to a mistake with a bitfield, two different values mapped to
the same feature bit.

A new somewhat backwards compatible interface was introduced
in Linux 3.12. A much longer report on the issue can be found
here:
https://lwn.net/Articles/567894/
Vince Weaver
Linux 3.12 adds PERF_SAMPLE_IDENTIFIER
A new PERF_SAMPLE_IDENTIFIER sample type was added in Linux 3.12.
Vince Weaver
E2BIG documentation
The following documents the E2BIG error return for
perf_event_open().

I actually ran into this error the hard way and it took me
half a day to figure out why my ->size value was changing.
Vince Weaver
Linux 3.12 adds PERF_EVENT_IOC_ID
A new perf_event related ioctl, PERF_EVENT_IOC_ID, was added
in Linux 3.12.
Vince Weaver
PERF_COUNT_SW_DUMMY support
Support for the PERF_COUNT_SW_DUMMY event type was added in
Linux 3.12.
Vince Weaver [Andreas Sandberg]
PERF_EVENT_IOC_PERIOD update
The PERF_EVENT_IOC_PERIOD ioctl was broken until 2.6.36,
and it turns out that the ARM architecture has some
differing behavior too.

pipe.2
Trevor Bramwell
Fix error in example program

poll.2
Michael Kerrisk [Paolo Bonzini]
Clarify meaning of events==0
events==0 does not mean that revents is always returned as
zero. The "output only" events (POLLHUP, POLLERR, POLLNVAL)
can still be returned.

See https://bugzilla.kernel.org/show_bug.cgi?id=61911

readlink.2
Michael Kerrisk [Yuanhang Zheng]
Fix typo in error message in example program

recv.2
Michael Kerrisk
Remove out-of-date statement that UNIX domain does not support MSG_TRUNC
Should have removed that sentence as part of
commit a25601b48b822eb1882ae336574b8d062a17e564

sched_get_priority_max.2
Michael Kerrisk
Add SCHED_IDLE to discussion

send.2
Michael Kerrisk
RETURN VALUE: these calls return number of bytes (not characters) sent

setreuid.2
Michael Kerrisk
Small clarification to description of when saved set-user-ID is set

sigpending.2
Michael Kerrisk
Note treatment of signals that are blocked *and* ignored

stat.2
Michael Kerrisk
Note filesystem support for nanosecond timestamps
Add some detail on which native filesystems do and don't
support nanosecond timestamps.
Michael Kerrisk
Cosmetic reworking of timestamp discussion in NOTES
Michael Kerrisk [Yang Yang]
Update discussion of nanosecond timestamps
The existing text describes the timestamp fields as 'time_t'
and delegates discussion of nanosecond timestamps under NOTES.
Nanosecond timestamps have been around for a while now,
and are in POSIX.1-2008, so reverse the orientation of the
discussion, putting the nanosecond fields into DESCRIPTION
and detailing the historical situation under NOTES.

symlink.2
Michael Kerrisk
Further fine tuning of argument names
Follow-up to f2ae6dde0c68448bec986d12fe32268a2c98bfd9
See https://sourceware.org/bugzilla/show_bug.cgi?id=16073

kcmp.3
Shawn Landden

malloc.3
Greg Price
Scale back promises of alignment
It's not true that the return value is suitably aligned for "any
variable"; for example, it's unsuitable for a variable like
float *x __attribute__ ((__vector_size__ (32)));
which requires 32-byte alignment. Types like this are defined in
, and with 16-byte alignment in and
, so the application programmer need not even know
that a vector_size attribute has been applied.

On an x86 architecture, a program that loads from or stores to a
pointer with this type derived from malloc can crash because GCC
generates an aligned load/store, like MOVDQA.

The C99 standard (TC3, as of N1256) does say the return value is
suitably aligned for "any type of object". The C11 standard (as
of N1570) revises this to any type with "fundamental alignment",
which means an alignment "supported by the implementation in all
contexts", which I suppose tautologically includes aligning
malloc/realloc return values.

The actual behavior of current glibc malloc is to align to the
greater of 2 * sizeof(size_t) and __alignof__ (long double),
which may be one bit greater than this commit promises.
