Serge Hallyn c60f4c530d cgroups.7: wfix 
Note though that I'm not sure about this.  Putting all the
cgroups under /sys/fs/cgroup is, i think, frowned upon now.
Certain lxc prefers mounts in a subdirectory of
/sys/fs/cgroup.

"IP_LEAVE_GROUP" does not exist. It was perhaps a confusion with
MCAST_LEAVE_GROUP. Change the text to IP_DROP_MEMBERSHIP which has
the same function as MCAST_LEAVE_GROUP and is documented in the
ip.7 man page.

_POSIX_SOURCE was a POSIX.1-1990 creation that was soon made
obsolete bu _POSIX_C_SOURCE. Retaining mention of it
in the feature test macro requirements section of the
SYNOPSIS doesn't contain important information, and may
mislead readers into actually trying to use this macro.
A few mentions of it a maintained in a some pages where
defining _POSIX_SOURCE inhibits some behavior.

point to the related man-pages.

pthreads are the main usage of futexes, refer to pthread.7.
Implementation of robust futexes requires knowledge of set_robust_list.2
and get_robust_list.2.
It is noworthy that a closing thread can wake up a futex. Hence mention
clone.2 and set_tid_address.2.

Namhyung Kim 3a0c27f88e rtld-audit.7: Fix (typo) error in la_pltenter() description 
s/la_pltenter()/la_pltexit()/

la_pltenter() is called regardless of the value of
framesizep but la_pltexit() is called only if la_pltenter()
returns with non-zero framesizep set.  I spent long time to
figure out why la_pltexit() is not called at all.

Quoting comments in glibc/sysdeps/x86_64/dl-trampoline.h:

  /* There's nothing in the frame size, so there
     will be no call to the _dl_call_pltexit. */

and

  /* At this point we need to prepare new stack for the function
     which has to be called.  We copy the original stack to a
     temporary buffer of the size specified by the 'framesize'
     returned from _dl_profile_fixup */

I think it's because it needs to preserve 'inregs' to be passed to
la_pltexit().

The _dl_profile_fixup() sets the '*framesizep' to maximum value of
what la_pltenter() sets.  Please see glibc/elf/dl-runtime.c file.

Michael Kerrisk e50eaaf192 nptl.7: Note that i386 and x86-64 binaries can't share mutexes 
Quoting Nicholas Miell:

    PTHREAD_PROCESS_SHARED says any thread with access to the
    memory containing the mutex can operate on the mutex and
    POSIX basically ignores the idea that different processes
    could be running completely incompatible executables or
    whatever.

    pthread_mutex_t has a bunch of #ifdefs in the middle of it
    that change the structure size and layout between i386 and
    x86_64.

    Most importantly, the positions of the __nusers and __kind
    fields are swapped (this looks to be an oversight dating
    back to 2003 when __nusers was first introduced and carefully
    preserved when the separate i386 and x86_64 versions of
    pthreadtypes.h were merged into the single x86 version),
    which means that when the lock and unlock functions attempt
    to figure out what kind of mutex it is
    (recursive/adaptive/whatever), they'll look at the wrong
    field if the mutex is from the wrong architecture and then
    things will break.

    And then there's the fact that the rest of the struct is a
    union in the 32-bit version and flat in the 64-bit version,
    but that could have been worked around if you put a flag in
    the __kind field that tells the 64-bit pthread library that
    it is looking at a 32-bit mutex.

Ben Woodard 8e83cef60d rtld-audit.7: Use correct printf() specifier for pointer types 
In the example code you used %x rather than %p in the example
code for an audit library. The problem is that it truncates the
pointers on 64b platforms. So you get something like:

la_symbind64(): symname = strrchr sym->st_value = 0x7f4b8a3f8960
ndx = 222 flags = 0x0 refcook = 8b53e5c8 defcook = 8b537e30

rather than:

la_symbind64(): symname = fclose sym->st_value = 0x7fa452dd49b0
ndx = 1135 flags = 0x0 refcook = 0x7fa453f395c8 defcook = 0x7fa453f32e30

This has bitten me a handful of times when playing around with
audit test libraries to investigate its behavior.
