[BZ #22342] Fix netgroup cache keys.
Unlike other nscd caches, the netgroup cache contains two types of
records - those for "iterate through a netgroup" (i.e. setnetgrent())
and those for "is this user in this netgroup" (i.e. innetgr()),
i.e. full and partial records. The timeout code assumes these records
have the same key for the group name, so that the collection of records
that is "this netgroup" can be expired as a unit.
However, the keys are not the same, as the in-netgroup key is generated
by nscd rather than being passed to it from elsewhere, and is generated
without the trailing NUL. All other keys have the trailing NUL, and as
noted in the linked BZ, debug statements confirm that two keys for the
same netgroup are added to the cache with two different lengths.
The result of this is that as records in the cache expire, the purge
code only cleans out one of the two types of entries, resulting in
stale, possibly incorrect, and possibly inconsistent cache data.
The patch simply includes the existing NUL in the computation for the
key length ('key' points to the char after the NUL, and 'group' to the
first char of the group, so 'key-group' includes the first char to the
NUL, inclusive).

Fix i386 fenv_private.h float128 for 32-bit --with-fpmath=sse (bug 22902).
As discussed in bug 22902, the i386 fenv_private.h implementation has
problems for float128 for the case of 32-bit glibc built with libgcc
from GCC configured using --with-fpmath=sse.
The optimized floating-point state handling in fenv_private.h needs to
know which floating-point state - x87 or SSE - is used for each
floating-point type, so that only one state needs updating / testing
for libm code using that state internally. On 32-bit x86, the x87
rounding mode is always used for float128, but the x87 exception flags
are only used when libgcc is built using x87 floating-point
arithmetic; if libgcc is built for SSE arithmetic, the SSE exception
flags are used.
The choice of arithmetic with which libgcc is built is independent of
that with which glibc is built. Thus, since glibc cannot tell the
choice used in libgcc, the default implementations of
libc_feholdexcept_setroundf128 and libc_feupdateenv_testf128 (which
use the <fenv.h> functions, thus using both x87 and SSE state on
processors that have both) need to be used; this patch updates the
code accordingly.

case.

Refactor atfork handlers
Current implementation (sysdeps/nptl/fork.c) replicates the atfork
handlers list backward to invoke the child handlers after fork/clone
syscall.
The internal atfork handlers is implemented as a single-linked list
so a lock-free algorithm can be used, trading fork mulithread call
performance for some code complexity and dynamic stack allocation
(since the backwards list should not fail).
This patch refactor it to use a dynarary instead of a linked list.
It simplifies the external variables need to be exported and also
the internal atfork handler member definition.
The downside is a serialization of fork call in multithread, since to
operate on the dynarray the internal lock should be used. However
as noted by Florian, it already acquires external locks for malloc
and libio so it is already hitting some lock contention. Besides,
posix_spawn should be faster and more scalable to run external programs
in multithread environments.

elf: Remove ad-hoc restrictions on dlopen callers [BZ #22787]
This looks like a post-exploitation hardening measure: If an attacker is
able to redirect execution flow, they could use that to load a DSO which
contains additional code (or perhaps make the stack executable).
However, the checks are not in the correct place to be effective: If
they are performed before the critical operation, an attacker with
sufficient control over execution flow could simply jump directly to
the code which performs the operation, bypassing the check. The check
would have to be executed unconditionally after the operation and
terminate the process in case a caller violation was detected.
Furthermore, in _dl_check_caller, there was a fallback reading global
writable data (GL(dl_rtld_map).l_map_start and
GL(dl_rtld_map).l_text_end), which could conceivably be targeted by an
attacker to disable the check, too.
Other critical functions (such as system) remain completely
unprotected, so the value of these additional checks does not appear
that large. Therefore this commit removes this functionality.

intl/tst-gettext: fix failure with newest msgfmt
Since upstream gettext commit
d13f165b83 (msgfmt: Remove
POT-Creation-Date field from the header in the output.), msgfmt does not
copy the POT-Creation-Date field in the header entry from the po file to
the mo file anymore. This breaks the assumption that we can test gettext
by comparing each message in the po files with the corresponding string
return by gettext. This makes the intl/tst-gettext to fail.
While it would have been possible to modify the po2test.awk script to
also strip the line POT-Creation-Date field when creating the msgs.h
file, it would not work with both the old and new msgfmt.
Instead create a tst-gettext-de.po file from de.po by removing the
POT-Creation-Date line. Another alternative would be to use a static
tst-gettext-de.po file, but I guess the reason for using de.po is to
also catch issues caused by newly added strings.
As tst-catgets also uses msg.h, it should also be updated. Instead of
using the new tst-gettext-de.po file, the patch modifies xopen-msg.awk

Document use of CC and CFLAGS in more detail (bug 20980, bug 21234).

addresses this by documenting the proper use of CC and CFLAGS in more
detail - saying what options should go where and specifying the
requirement to compile with optimization.
The previous text incorrectly used @var markup with CC and CFLAGS.
The correct markup for environment variables is @env, but it's also
the case that passing such variables explicitly on the configure
command line is preferred to passing them in the environment, so this
patch changes the documentation to describe passing them on the
command line (and uses @code).

Fix hppa local PLT entries for sigprocmask (bug 18124).
When adding/updating localplt.data for various architectures to get

nscd: don't unconditionally use PTHREAD_RWLOCK_WRITER_NONRECURSIVE_INITIALIZER_NP
PTHREAD_RWLOCK_WRITER_NONRECURSIVE_INITIALIZER_NP is Linux-only.
* nscd/connections.c (RWLOCK_INITIALIZER): Define to
PTHREAD_RWLOCK_WRITER_NONRECURSIVE_INITIALIZER_NP or
PTHREAD_RWLOCK_INITIALIZER if that is not available.

linux/aarch64: sync sys/ptrace.h with Linux 4.15 [BZ #22433]
Remove compat-specific constants that were never exported by kernel
headers under these names. Before linux commit v3.7-rc1~16^2~1 they
were exported with COMPAT_ prefix, and since that commit they are not
exported at all.
* sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (__ptrace_request):
Remove arm-specific PTRACE_GET_THREAD_AREA, PTRACE_GETHBPREGS,
and PTRACE_SETHBPREGS.

[BZ #22830] malloc_stats: restore cancellation for stderr correctly.
malloc_stats means to disable cancellation for writes to stderr while
it runs, but it restores stderr->_flags2 with |= instead of =, so what
it actually does is disable cancellation on stderr permanently.
[BZ #22830]
* malloc/malloc.c (__malloc_stats): Restore stderr->_flags2
correctly.
* malloc/tst-malloc-stats-cancellation.c: New test case.
* malloc/Makefile: Add new test case.
