* Remove redundant GAIH_OKIFUNSPEC and GAIH_EAI.Pavel Simerda2013-12-021-17/+14
| | | | | | | | | | | 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.

* Fix typo in sys/ptrace.h.Carlos O'Donell2013-11-251-1/+1
| | | | | | | The event code is PTRACE_EVENT_SECCOMP, not PTRAVE_EVENT_SECCOMP. This patch fixes the V->C typo. There are no ABI issues since the number remains the same for the code. Code using the old wrong name will need to be updated.

* PowerPC: Set/restore rounding mode only when neededAdhemerval Zanella2013-11-257-25/+293
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch helps some math functions performance by adding the libc_fexxx variant of inline functions to handle both FPU round and exception set/restore and by using them on the libc_fexxx_ctx functions. It is based on already coded fexxx family functions for PPC with fpu. Here is the summary of performance improvements due this patch (measured on a POWER7 machine): Before: cos(): ITERS:9.5895e+07: TOTAL:5116.03Mcy, MAX:77.6cy, MIN:49.792cy, 18744 calls/Mcy exp(): ITERS:2.827e+07: TOTAL:5187.15Mcy, MAX:494.018cy, MIN:38.422cy, 5450.01 calls/Mcy pow(): ITERS:6.1705e+07: TOTAL:5144.26Mcy, MAX:171.95cy, MIN:29.935cy, 11994.9 calls/Mcy sin(): ITERS:8.6898e+07: TOTAL:5117.06Mcy, MAX:83.841cy, MIN:46.582cy, 16982 calls/Mcy tan(): ITERS:2.9473e+07: TOTAL:5115.39Mcy, MAX:191.017cy, MIN:172.352cy, 5761.63 calls/Mcy After: cos(): ITERS:2.05265e+08: TOTAL:5111.37Mcy, MAX:78.754cy, MIN:24.196cy, 40158.5 calls/Mcy exp(): ITERS:3.341e+07: TOTAL:5170.84Mcy, MAX:476.317cy, MIN:15.574cy, 6461.23 calls/Mcy pow(): ITERS:7.6153e+07: TOTAL:5129.1Mcy, MAX:147.5cy, MIN:30.916cy, 14847.2 calls/Mcy sin(): ITERS:1.58816e+08: TOTAL:5115.11Mcy, MAX:1490.39cy, MIN:22.341cy, 31048.4 calls/Mcy tan(): ITERS:3.4964e+07: TOTAL:5114.18Mcy, MAX:177.422cy, MIN:146.115cy, 6836.68 calls/Mcy
* Adjust generic swapon prototype to match Linux version.Roland McGrath2013-11-211-1/+1
|
* Don't use broken DL_AUTO_FUNCTION_ADDRESS()Guy Martin2013-11-211-2/+3
| | | | | | | | | | | | On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the variable fptr[2] in it's own scope. The content of fptr[] is thus undefined right after the macro exits. Newer gcc's (>= 4.7) reuse the stack space of this variable triggering a segmentation fault in dl-init.c:69. To fix this we rewrite the macros to make the call directly to init and fini without needing to pass back a constructed function pointer.
* Add systemtap probe markers for sin, cos, asin and acosSiddhesh Poyarekar2013-11-201-0/+5
|
* Make powerpc-nofpu floating-point state thread-local (bug 15483).Joseph Myers2013-11-1918-67/+104

* PowerPC: Fix __fe_mask_env exportAdhemerval Zanella2013-11-132-2/+2
| | | | Change SHLIB_COMPAT calls to GLIBC_2_19 for __fe_nomask_env symbol.
* Set arch_minimum_kernel to 3.4.0 for x32H.J. Lu2013-11-132-0/+6
| | | | x32 ABI support was added in Linux kernel 3.4.0.
* PowerPC: Fix __fe_mask_env exportAdhemerval Zanella2013-11-135-13/+13
| | | | | This patch does not export __fe_mask_env anymore, only providing a compatibility symbol. It fixes BZ#14143.
* Fix sparc 64-bit GMP ifunc resolution in static builds.David S. Miller2013-11-125-5/+5
| | | | | | | | | | [BZ #16150] * sysdeps/sparc/sparc64/multiarch/add_n.S: Resolve to the correct generic symbol in the non-vis3 case in static builds. * sysdeps/sparc/sparc64/multiarch/addmul_1.S: Likewise. * sysdeps/sparc/sparc64/multiarch/mul_1.S: Likewise. * sysdeps/sparc/sparc64/multiarch/sub_n.S: Likewise. * sysdeps/sparc/sparc64/multiarch/submul_1.S: Likewise.
* PowerPC: Fix vDSO missing ODP entriesAdhemerval Zanella2013-11-083-5/+28
| | | | | | | This patch fixes the vDSO symbol used directed in IFUNC resolver where they do not have an associated ODP entry leading to undefined behavior in some cases. It adds an artificial OPD static entry to such cases and set its TOC to non 0 to avoid triggering lazy resolutions.
* Fix build on pre-v9 32-bit Sparc.David S. Miller2013-11-061-1/+2
| | | | | | | | | We cannot use fnegd in this code, as fnegd was added in v9. Only fnegs exists in v8 and earlier. [BZ #15985] * sysdeps/sparc/sparc32/fpu/s_fdim.S (__fdim): Do not use fnegd on pre-v9 cpus, use a fnegs+fmovs sequence instead.
* Restrict shm_open and shm_unlink to SHMDIR. Fixes bugs 14752 and 15763.Ondřej Bílka2013-10-311-6/+8

* rename configure.in to configure.acMike Frysinger2013-10-3032-16/+16
| | | | | | | Autoconf has been deprecating configure.in for quite a long time. Rename all our configure.in and preconfigure.in files to .ac. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Consolidate conditionals in mp sin/cos functionsSiddhesh Poyarekar2013-10-281-8/+6
| | | | | Consolidate conditionals in multiple precision sin and cos functions to prepare the code for addition of probe points.
* PowerPC: strcpy/stpcpy optimization for PPC64/POWER7Adhemerval Zanella2013-10-254-134/+407
| | | | | | | | | | This patch intends to unify both strcpy and stpcpy implementationsi for PPC64 and PPC64/POWER7. The idead default powerpc64 implementation is to provide both doubleword and word aligned memory access. For PPC64/POWER7 is also provide doubleword and word memory access, remove the branch hints, use the cmpb instruction for compare doubleword/words, and add an optimization for inputs of same alignment.
* Fix stack overflow due to large AF_INET6 requestsSiddhesh Poyarekar2013-10-251-2/+18
| | | | | | | | 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.
* Fix incorrect getaddrinfo assertion triggerAllan McRae2013-10-251-3/+10
| | | | | | | | | | | | | | | | | | | [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.
