Changes to individual pages
---------------------------
clone.2

Michael Kerrisk
CLONE_NEWIPC governs mechanisms that don't have filesystem pathnames
Michael Kerrisk
CLONE_NEWIPC doesn't mount the POSIX MQ file system
Michael Kerrisk
Add an example program (CLONE_NEWUTS)
Michael Kerrisk
Some reworking of CLONE_NEWIPC text
No substantial content changes.
Michael Kerrisk
SEE ALSO: add kcmp(2)
SEE ALSO: add setns(2)
fallocate.2
Michael Kerrisk
FALLOC_FL_* flags are defined in glibc only since 2.18
getxattr.2
removexattr.2
setxattr.2
Michael Kerrisk [Andrew Perepechko, ]
Note that ENOATTR is a synonym for ENODATA
Various people have pointed out that strace(1) shows ENODATA
for the case where the named attribute does not exist, or
the process has no access to this attribute. ENODATA
and ENOATTR are in fact defined as synonyms. Point this out
in the man page, so that people understand the strace(1) info.
See https://bugzilla.kernel.org/show_bug.cgi?id=51871
getxattr.2
listxattr.2
removexattr.2
setxattr.2
Michael Kerrisk
Put errors under ERRORS section
The errno values on these pages were listed in a nonstandard
way under the RETURN VALUE section. Put them in ERRORS sections.
init_module.2
Michael Kerrisk [Rusty Russell]
ERRORS: Add errors for module signatures (EBADMSG, ENOKEY)
link.2
mkdir.2
mknod.2
open.2
rename.2
symlink.2
write.2
mkfifo.3
Mark Hills
Document EDQUOT error
The return error EDQUOT is not documented in open(2), write(2),
symlink(2) etc.
Whether inodes or disk blocks are required for each function
is something I based on received wisdom and BSD documentation,
rather than tracing the code to the kernel. For symlink(2)
this certainly depends on the file system type.
listxattr.2
Michael Kerrisk [Theodore Ts'o]
Fix RETURN VALUE description
On success, 0 may be returned, so change wording from
"positive number" to "nonnegative number".
outb.2
Michael Kerrisk
Add SYNOPSIS
prctl.2
Kees Cook
Document PR_SET_PTRACER
Document the Yama LSM's prctl handler that allows processes to
declare ptrace restriction exception relationships via
PR_SET_PTRACER.
Michael Kerrisk
Make it explicit that PR_SET_PTRACER replaces previous setting
The attribute is a scalar, not a list.
Shawn Landden
Document EINVAL error for PR_SET_PTRACER
Michael Kerrisk
Document PR_GET_TID_ADDRESS
ptrace.2
Michael Kerrisk

Must be called using syscall(2)
Yes, the call is way obsolete, but add this info
for completeness.
recvmmsg.2
Elie De Brauwer
Add/correct kernel version info for recvmmsg() and MSG_WAITFORNONE
This patch isolates the since/version related fixes as requested.
This change introduces the following delta:
* The page states it was added in 2.6.32 but it is only added
2.6.33 (ref: http://kernelnewbies.org/Linux_2_6_33)
* The MSG_WAITFORONE flag was in turn only added in 2.6.34
(ref: http://kernelnewbies.org/Linux_2_6_34)

Clarify suid_dumpable versus core_pattern

references.
Justin Lebar
statm's "shared" field refers to pages backed by files
I noticed that statm's "shared" field doesn't match the sum of
all the "shared" entries in smaps [1].
The kernel docs explain that statm's "shared" field is "number of
pages that are shared (i.e. backed by a file)" [2]. smaps appears
to call a page shared if it's mapped by at least two processes,
which explains this discrepancy.
I'm not a kernel hacker, but it appears to me they do mean "i.e."
and not "e.g." in the statm description: In
fs/proc/task_mmu.c::task_statm, I see
*shared = get_mm_counter(mm, MM_FILEPAGES);
Here's a patch which updates the man page to match the (hopefully
correct) kernel docs.
