* Preserve errno across _PC_CHOWN_RESTRICTED call on XFSSiddhesh Poyarekar2013-04-031-1/+2
| | | | | | | | | | | | | | Fix BZ #15305. On kernel versions earlier than 2.6.29, the Linux kernel exported a sysctl called restrict_chown for xfs, which could be used to allow chown to users other than the owner. 2.6.29 removed this support, causing the open_not_cancel_2 to fail and thus modify errno. The fix is to save and restore errno so that the caller sees it as unmodified. Additionally, since the code to check the sysctl is not useful on newer kernels, we add an ifdef so that in future the code block gets rmeoved completely.

* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).Thomas Schwinge2013-04-021-0/+2
| | | | It is based on draft TS 18661 and currently enabled as a GNU extension.

* Don't add input group during initgroups_dyn in hesiodSiddhesh Poyarekar2013-03-281-1/+1
| | | | | | | | | | | | | Fixes BZ #15304. The *initgroups_dyn functions are called with a group argument. This group gid is usually skipped while populating the grouplist since the caller adds that group id in advance. The hesiod initgroups_dyn implementation however adds the group gid to the list if it does not already exist. While it works fine for the usual initgroups, it breaks nscd since it calls initgroups_dyn with -1 as the gid (to have all groups included).
* Fix casinh inaccuracy near i, imaginary part > 1 (bug 15307).Joseph Myers2013-03-271-1/+1

* BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibmAdhemerval Zanella2013-03-221-4/+4
| | | | | | The patch increase the high value to check if expl overflows. Current high mark value is not really correct, the algorithm accepts high values. It also adds a correct wrapper function to check for overflow and underflow.
* BZ#11120: fix x86_64/strcmp.S NOT_IN_libc safeguardsDmitry V. Levin2013-03-221-8/+8
| | | | | | | | Due to a typo repeated several times, this bug hasn't been fixed yet, despite being marked as resolved in glibc 2.12. * sysdeps/x86_64/strcmp.S: Replace all occurrences of NOT_IN_lib with NOT_IN_libc.
* Fix Bessel function spurious overflows for ldbl-128 / ldbl-128ibm (bug 15285).Joseph Myers2013-03-211-1/+1

* Move BZ#11261 from 2.18 to 2.16 bug list.Carlos O'Donell2013-03-171-20/+20
| | | | | | BZ#11261 was fixed in the 2.16 release even if we only found out that it was fixed in the 2.18 release. Testing shows it is fixed in the 2.16 release so we add it to that NEWS section.
* BZ#11261 fixed by previous commit.Carlos O'Donell2013-03-171-3/+3
| | | | | | Fixed by 41b81892f11fe1353123e892158b53de73863d62. Verified fixed by using test case in BZ#11261.

|
* Remove PIPE_BUF Linux-specific codeSiddhesh Poyarekar2013-03-071-3/+3
| | | | | | | | Fixes BZ #12723 The variable pipe buffer size does nothing to the value of PIPE_BUF, since the number of bytes that are atomically written is still PIPE_BUF on Linux.

* Revert GLIBC_PTHREAD_DEFAULT_STACKSIZE changes.Carlos O'Donell2013-03-011-4/+0
| | | | | | | This reverts the change that allows the POSIX Thread default stack size to be changed by the environment variable GLIBC_PTHREAD_DEFAULT_STACKSIZE. It has been requested that more discussion happen before this change goes into 2.18.

* MIPS: Respect the legacy syscall restart convention.Maciej W. Rozycki2013-02-051-1/+1
| | | | | | | | | | | | | | | That convention requires the instruction immediately preceding SYSCALL to initialize $v0 with the syscall number. Then if a restart triggers, $v0 will have been clobbered by the syscall interrupted, and needs to be reinititalized. The kernel will decrement the PC by 4 before switching back to the user mode so that $v0 has been reloaded before SYSCALL is executed again. This implies the place $v0 is loaded from must be preserved across a syscall, e.g. an immediate, static register, stack slot, etc. The restriction was lifted with Linux 2.6.36 kernel release and no special requirements are placed around the SYSCALL instruction anymore, however we still support older kernel binaries.
