Newly documented interfaces in existing 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.
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.
Global changes
--------------
Various pages
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'
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
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
prctl.2
Michael Kerrisk
Note equivalents of PR_SET_NAME
pthread_setname_np() and pthread_getname_np() and
/proc/self/task/TID/comm provide access to the same
attribute.
pread.2
Michael Kerrisk [Марк Коренберг]
pread() and pwrite() are especially useful in multithreaded applications
