bef8fd6013 Fix qsort_r namespace (bug 17571).
qsort_r is defined in the same file as qsort, but is not an ISO C
function, so should be a weak alias for __qsort_r.  The uses in
getaddrinfo should also call __qsort_r, since getaddrinfo is a POSIX
function and qsort_r isn't.  This patch implements this.  Because nscd
uses the getaddrinfo sources outside libc, as do the tst-rfc3484
tests, a #define of __qsort_r to qsort_r is added there alongside the
similar defines for other libc-internal symbols used in getaddrinfo.

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

	[BZ #17571]
	* stdlib/msort.c (qsort_r): Rename to __qsort_r and define as weak
	alias of __qsort_r.

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).

61fe374a44 Remove _POSIX_REGEX_VERSION
There is no _POSIX_REGEX_VERSION, so don't check for it.
_REGEX_VERSION has been removed as well[1], so only keep the -1 return
for backward compatibility.  I found this when trying to make the
getconf environment variables typo-proof.

	* sysdeps/posix/sysconf.c (__sysconf): Return -1 for

c7aec4beb1 sysdeps/posix/tempname.c: Merge from gnulib
Partial merge from gnulib which fixes a number of -Wundef warnings.
The parts that differ from gnulib are the header comment, use of
__glibc_unlikely, a #define of __secure_getenv and the use of tabs.
The majority of the patch is cosmetic comment changes, the only runtime
change is an abort if an unknown kind is passed to __gen_tempname.

ChangeLog:

2014-06-25  Will Newton  <will.newton@linaro.org>

	* sysdeps/posix/tempname.c: Merge from gnulib, cosmetic
	comment changes throughout the file.  Remove checks
	for HAVE_*_H definitions that are not required.
	(__gen_tempname): Call abort if an unknown kind value is
	passed.

cf26a0cb6a Return EAI_AGAIN for AF_UNSPEC when herrno is TRY_AGAIN (BZ #16849)
getaddrinfo correctly returns EAI_AGAIN for AF_INET and AF_INET6
queries.  For AF_UNSPEC however, an older change
(a682a1bf55) broke the check and due to
that the returned error was EAI_NONAME.

This patch fixes the check so that a non-authoritative not-found is
returned as EAI_AGAIN to the user instead of EAI_NONAME.

a88ddc902b Use statvfs64() for pathconf(_PC_NAME_MAX).
pathconf(_PC_NAME_MAX) was implemented on top of statfs().  The 32bit
version therefore fails EOVERFLOW if the filesystem blockcount is
sufficiently large.

Most pathconf() queries use statvfs64(), which avoids this issue.  This
patch modifies pathconf(_PC_NAME_MAX) to do likewise.

a071766ebf Fix use of half-initialized result in getaddrinfo when using nscd (bug 16743)
This fixes a bug in the way the results from __nscd_getai are collected:
for every returned result a new entry is first added to the
gaih_addrtuple list, but if that result doesn't match the request this
entry remains uninitialized.  So for this non-matching result an extra
result with uninitialized content is returned.

To reproduce (with nscd running):

	$ getent ahostsv4 localhost
	127.0.0.1       STREAM localhost
	127.0.0.1       DGRAM
	127.0.0.1       RAW
	(null)          STREAM

We needlessly enabled thread cancellation before it was necessary. As
only call that needs to be guarded is waitpid which is cancellation
point we could remove cancellation altogether.

639a0ef8ab Remove redundant GAIH_OKIFUNSPEC and GAIH_EAI.
Only gaih_inet() and gaih_inet_serv() use a special bit flag denoted
by the GAIH_OKIFUNSPEC macro. Only the return value of
gaih_inet_serv() is actively checked for the bit flag which is
redundant because it just copies the nonzero property of the value
otherwise returned. The return value of gaih_inet() is only checked
for being zero and then the bit flag is filtered out. As the bit flag
is set only for otherwise nonzero return values, it doesn't affect the
zero comparison. GAIH_EAI just an alias to ~GAIH_OKIFUNSPEC.

Resolves #16072 (CVE-2013-4458).

but the AF_INET6 case went undetected back then.

894f3f1049 Fix incorrect getaddrinfo assertion trigger
[BZ #9954]

With the following /etc/hosts:
127.0.0.1       www.my-domain.es
127.0.1.1       www.my-domain.es
192.168.0.1     www.my-domain.es

Using getaddrinfo() on www.my-domain.es, trigger the following assertion:
../sysdeps/posix/getaddrinfo.c:1473: rfc3484_sort: Assertion
`src->results[i].native == -1 || src->results[i].native == a1_native' failed.

This is due to two different bugs:
- In rfc3484_sort() rule 7, src->results[i].native is assigned even if
src->results[i].index is -1, meaning that no interface is associated.
- In getaddrinfo() the source IP address used with the lo interface needs a
special case, as it can be any IP within 127.X.Y.Z.

3d04f5db20 Set EAI_SYSTEM only when h_errno is NETDB_INTERNAL
Fixes BZ #15339.

NSS_STATUS_UNAVAIL may mean that a necessary input resource is not
available.  This could occur in a number of cases including when the
network is down, system runs out of file descriptors, etc.  The
correct differentiator in such a case is the h_errno, which gives the
nature of failure.  In case of failures other than a simple 'not
found', we set h_errno as NETDB_INTERNAL and let errno be the
identifier for the exact error.

017678433c Suppress incorrect link warnings for NSS symbols
When glibc is built with --enable-static-nss, the warning that
using NSS symbols requires the nss shared objects to be present
is no longer true, as those symbols are built into libc.  Suppress
the warning for those symbols by providing a new macro
(nss_interface_function) for the NSS functions that is defined as
static_link_warning in the normal case, and empty for static NSS.

3a2c02424d Cache network interface information
Whenever getaddrinfo needed network interface information it used the
netlink interface to read the information every single time.  The
problem is that this information can change at any time.

The patch implements monitoring of the network interfaces through
nscd.  If no change is detected the previously read information can
be reused (which is the norm).  This timestamp information is also
made available to other processes using the shared memory segment
between nscd and those processes.

getaddrinfo works around the resolver functionality to avoid automatic
IPv6 lookups.  The restoring didn't allow for the resolver to set
additional bits in _res.

7fb90fb89b Fix Linux getcwd for long paths
The getcwd syscall (so far?) can only handle path up to one page
in size.  There is no limit about directory hierarchy depth, though,
and the POSIX getcwd is supposed to handle this.  In that case fall
back to the generic getcwd.

Additionally, optimize the generic getcwd to use openat when possible
to change the asymptotic performance from O(N^2) to O(n).

7c9302908e Don't abort immediately on successful lookup in getaddrinfo.
When not using gethostbyname4 methods we immediately aborted the loop
over the nss modules on the first successful lookup.  While this is
almost always what is wanted the nsswitch.conf file allows to select
something different.
