2014-08-21Remove unnecessary uses of NOT_IN_libcSiddhesh Poyarekar
If a IS_IN_* macro is defined, then NOT_IN_libc is always defined, except obviously for IS_IN_libc. There's no need to check for both. Verified on x86_64 and i686 that the source is unchanged. * include/libc-symbols.h: Remove unnecessary check for NOT_IN_libc. * nptl/pthreadP.h: Likewise. * sysdeps/aarch64/setjmp.S: Likewise. * sysdeps/alpha/setjmp.S: Likewise. * sysdeps/arm/sysdep.h: Likewise. * sysdeps/i386/setjmp.S: Likewise. * sysdeps/m68k/setjmp.c: Likewise. * sysdeps/posix/getcwd.c: Likewise. * sysdeps/powerpc/powerpc32/setjmp-common.S: Likewise. * sysdeps/powerpc/powerpc64/setjmp-common.S: Likewise. * sysdeps/s390/s390-32/setjmp.S: Likewise. * sysdeps/s390/s390-64/setjmp.S: Likewise. * sysdeps/sh/sh3/setjmp.S: Likewise. * sysdeps/sh/sh4/setjmp.S: Likewise. * sysdeps/unix/alpha/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/aarch64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/ia64/setjmp.S: Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sh/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/tile/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise. * sysdeps/x86_64/setjmp.S: Likewise.

2014-06-25sysdeps/posix/tempname.c: Merge from gnulibWill Newton
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.
2014-05-15Return EAI_AGAIN for AF_UNSPEC when herrno is TRY_AGAIN (BZ #16849)Siddhesh Poyarekar
getaddrinfo correctly returns EAI_AGAIN for AF_INET and AF_INET6 queries. For AF_UNSPEC however, an older change (a682a1bf553b1efe4dbb03207fece5b719cec482) 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.

2014-04-09Use statvfs64() for pathconf(_PC_NAME_MAX).Peter TB Brett
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.
2014-03-24Fix use of half-initialized result in getaddrinfo when using nscd (bug 16743)Andreas Schwab
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 (null) DGRAM (null) RAW

2014-01-15Do not enable asynchronous cancellation in system. Fixes bug 14782.Ondřej Bílka
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.

2013-12-02Remove redundant GAIH_OKIFUNSPEC and GAIH_EAI.Pavel Simerda
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.

2013-10-25Fix stack overflow due to large AF_INET6 requestsSiddhesh Poyarekar
Resolves #16072 (CVE-2013-4458). This patch fixes another stack overflow in getaddrinfo when it is called with AF_INET6. The AF_UNSPEC case was fixed as CVE-2013-1914, but the AF_INET6 case went undetected back then.
2013-10-25Fix incorrect getaddrinfo assertion triggerAllan McRae
[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.

2013-06-11Fix symbol definitions for __clock_* functionsSiddhesh Poyarekar
__clock_gettime and other __clock_* functions could result in an extra PLT reference within libc.so if it actually gets used. None of the code currently uses them, which is why this probably went unnoticed.

2013-05-21Set EAI_SYSTEM only when h_errno is NETDB_INTERNALSiddhesh Poyarekar
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.

2012-10-30Suppress incorrect link warnings for NSS symbolsChris Metcalf
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.
