65f6f938cd linux: open and openat ignore 'mode' with O_TMPFILE in flags
Both open and openat load their last argument 'mode' lazily, using
va_arg() only if O_CREAT is found in oflag. This is wrong, mode is also
necessary if O_TMPFILE is in oflag.

By chance on x86_64, the problem wasn't evident when using O_TMPFILE
with open, as the 3rd argument of open, even when not loaded with
va_arg, is left untouched in RDX, where the syscall expects it.

However, openat was not so lucky, and O_TMPFILE couldn't be used: mode
is the 4th argument, in RCX, but the syscall expects its 4th argument in
a different register than the glibc wrapper, in R10.

Introduce a macro __OPEN_NEEDS_MODE (oflag) to test if either O_CREAT or
O_TMPFILE is set in oflag.

Tested on Linux x86_64.

9a44d530c4 Fix resolver if_* namespace (bug 17717).
Resolver code, brought in by pthreads (at least), uses if_* interfaces
that weren't in POSIX before 2001, resulting in linknamespace
failures.  This patch changes those interfaces to be weak aliases of
__if_* and makes the resolver use __if_* directly.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by this patch).

c5c2b7c3fd Fix pthreads getrlimit, gettimeofday namespace (bug 17682).
Some pthreads functions use getrlimit and gettimeofday, but these
functions are XSI, not base POSIX; this is a namespace issue for
dynamic linking as well as static linking.  This patch makes them use
__getrlimit and __gettimeofday instead - the former needed to be newly
exported from libc.so at GLIBC_PRIVATE (and so now needs
libc_hidden_proto / libc_hidden_def), the latter was already exported.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).

e0cfa51064 hurd: Fix dlopening libraries from static programs
dlopening libraries from a static program would dlopen libc.so,
which thus needs its own initialization, done in posixland_init,
which was missing initializing RPCs so far.

	* sysdeps/mach/hurd/i386/init-first.c (posixland_init): Call

2f5c1b000a Fix __getcwd rewinddir namespace (bug 17584).
__getcwd is called from dcigettext.o (brought in by various ISO C
functionality), but calls rewinddir, which is not an ISO C function.
This patch makes __getcwd call __rewinddir instead and makes rewinddir
a weak alias for __rewinddir.

Since getcwd.c is shared with gnulib (albeit not merged in either
direction for a long time, and omitted from gnulib's
config/srclist.txt list of shared files) I put in a #ifndef _LIBC
define of __rewinddir to rewinddir, although a future merged version
of getcwd could end up looking significantly different.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by this patch).

af296fcdab Remove bitrotten --enable-oldest-abi (bug 6652).
This patch removes the --enable-oldest-abi configure option, which has
long been bitrotten (as reported in bug 6652).  The principle of
removing this option was agreed in the thread starting at
<https://sourceware.org/ml/libc-alpha/2013-07/msg00174.html>.

Tested for x86_64 and x86 that the installed shared libraries other
than libc.so are unchanged by this patch and that libc.so disassembly
and symbol versions are unchanged (debug info changes because of
changed line numbers in csu/version.c).

ba90e05052 Remove configuration name patterns from shlib-versions.
This patch removes the first column (patterns matching configuration
names) from shlib-versions, leaving shlib-versions entry selection
based purely on sysdeps directories.

An implication of this removal is that the default for any non-Linux
ports using NPTL will be the same SONAMEs for NPTL libraries as for
Linux (as those defaults, previously limited to .*-.*-linux.*, are
left in nptl/shlib-versions and nptl_db/shlib-versions).

Special host_os handling in configure.ac that was purely for
shlib-versions is removed.  (The host_os setting is still used for
libc-abis - see
<https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding
that - but no entries there are affected by this change.)

Tested on x86_64 and x86 that the installed shared libraries are
unchanged by this patch.

c729e7c13a Move OS-specific shlib-versions entries to sysdeps files.
This patch moves OS-specific entries in the top-level shlib-versions
file to appropriate sysdeps directories.  I left the entries in
nptl/shlib-versions and nptl_db/shlib-versions unchanged; I think it
can be for those doing non-Linux NPTL-using ports to figure out
whether those entries should actually be OS-independent or should move
to sysdeps.

Given these two patches, I think the only further change needed before
the first column of shlib-versions can be eliminated will be changing
sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions to use %ifdef
to distinguish BE and LE configurations, instead of relying on the
powerpc64-.*-linux.* and powerpc.*le-.*-linux.* patterns.

Tested on x86_64 that the installed shared libraries are unchanged by
this patch.

	* shlib-versions: Remove OS-specific entries.  Moved to files in
	sysdeps.
	* sysdeps/mach/hurd/shlib-versions: New file.
	* sysdeps/unix/sysv/linux/shlib-versions: Likewise.

17a62de1ff Fix hang on fork
If e.g. a signal is being received while we are running fork(), the signal
thread may be having our SS lock when we make the space copy, and thus in the
child we can not take the SS lock any more.

* sysdeps/mach/hurd/fork.c (__fork): Lock SS->lock around __proc_dostop call.

acd7f096d7 Complete _BSD_SOURCE / _SVID_source followup cleanup.
This patch completes the headers cleanup consequent on removal of
_BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations):

* #endif conditionals that referred to BSD or SVID are updated.

* Redundant __USE_* tests in cases involving __USE_MISC are removed.
  This includes cases such as __USE_MISC || __USE_ISOC99, where
  __USE_MISC is redundant (because __USE_MISC is only ever defined in
  the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99
  is also defined; the same applies to the non-XSI-extended POSIX
  versions), and cases involving __USE_GNU, where __USE_GNU is
  redundant (because if __USE_GNU is defined, so are the other __USE_*
  macros).  There may well be other cases of __USE_FOO || __USE_BAR
  tests that could be simplified because one macro implies the other;
  this patch only addresses cases involving __USE_MISC.

498afc54df Combine __USE_BSD and __USE_SVID into __USE_MISC.
This patch cleans up following the obsoletion of _BSD_SOURCE and
_SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC.

The only non-mechanical part of this patch is the changes to
features.h; everything else is simple substitution of __USE_MISC for
the old macros.  Thus, this patch leaves obviously redundant
conditionals such as "defined __USE_MISC || defined __USE_MISC", and
does not update #endif comments where they referred to BSD or SVID in
words instead of the literal macro name.  This is intended to
facilitate patch review by separating the less mechanical changes from
these purely mechanical changes into a separate patch.  (I do intend
to integrate all the changes from
<https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I
believe includes all the trailing comment updates, in subsequent
patches.)

ef7344f09c Flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd.
As discussed in
<https://sourceware.org/ml/libc-alpha/2012-04/msg00840.html> and
<https://sourceware.org/ml/libc-alpha/2012-04/msg00989.html>, it seems
appropriate to flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd.

The bulk of the patch is just moving files.  The only other changes
are: update paths in sysdeps/mach/hurd/Implies and
sysdeps/unix/sysv/linux/wait3.c; merge the two syscalls.list files,
with the removal of syscalls that were in
sysdeps/unix/bsd/syscalls.list but overridden in the bsd4.4 directory
by .c files there.

Tested x86_64.  The installed shared libraries are identical before
and after the patch except for libc.so where the move of wait3.c
(included by sysdeps/unix/sysv/linux/wait3.c) affects debug info, but
the disassembly is unchanged.

	* sysdeps/mach/hurd/Implies: Change unix/bsd/bsd4.4 to unix/bsd.
