2014-09-05Use NSS_STATUS_TRYAGAIN to indicate insufficient buffer (BZ #16878)Siddhesh Poyarekar4-9/+19
The netgroups nss modules in the glibc tree use NSS_STATUS_UNAVAIL (with errno as ERANGE) when the supplied buffer does not have sufficient space for the result. This is wrong, because the canonical way to indicate insufficient buffer is to set the errno to ERANGE and the status to NSS_STATUS_TRYAGAIN, as is used by all other modules. This fixes nscd behaviour when the nss_ldap module returns NSS_STATUS_TRYAGAIN to indicate that a netgroup entry is too long to fit into the supplied buffer. (cherry picked from commit c3ec475c5dd16499aa040908e11d382c3ded9692) Conflicts: NEWS
2014-09-05Provide correct buffer length to netgroup queries in nscd (BZ #16695)Siddhesh Poyarekar3-3/+9
The buffer to query netgroup entries is allocated sufficient space for the netgroup entries and the key to be appended at the end, but it sends in an incorrect available length to the NSS netgroup query functions, resulting in overflow of the buffer in some special cases. The fix here is to factor in the key length when sending the available buffer and buffer length to the query functions.

2014-08-28PowerPC: Fix gprof entry point for LEAdhemerval Zanella3-1/+9
This patch fixes the ELFv2 gprof entry point since the ABI does not define function descriptors. It fixes BZ#17213. This is a backport of a53fbd8e6cd2f69bdfa3431d616a5f332aea6664.
2014-08-28Correct DT_PPC64_NUMAlan Modra3-2/+8
[BZ #17153] * elf/elf.h (DT_PPC64_NUM): Correct value. * NEWS: Add to fixed bug list. This is a backport of f6c44d475104e931bab2b4ffa499961088de673c.
2014-08-28PowerPC: Cleanup powerpc memmoveAdhemerval Zanella6-25/+15
Now that MEMCPY_OK_FOR_FWD_MEMMOVE should be define on memcopy.h there is no need to specialized powerpc memmove implementation. This patch moves the define set to powerpc memcopy and cleanup its definition on powerpc code.
2014-08-28PowerPC: Fix compiler warningsAdhemerval Zanella4-3/+12
This patch fixes some compiler due trailing data in #undef directives and due missing prototypes.
2014-08-28PowerPC: Add ifunc tests for memmoveAdhemerval Zanella2-0/+11
This patch add the missing ifunc tests definition for memmove ppc32 optimization patch (commit 07aedd7). This is a backport of 91f4b564bd7bedcd93e7047cad570ce292d6330b.
2014-08-28PowerPC: Align power7 memcpy using VSX to quadwordAdhemerval Zanella3-20/+10
This patch changes power7 memcpy to use VSX instructions only when memory is aligned to quardword. It is to avoid unaligned kernel traps on non-cacheable memory (for instance, memory-mapped I/O).
2014-08-28PowerPC: optimized memmove for POWER7/PPC32Adhemerval Zanella5-1/+109
This patch adds a optimized memmove for power7 by using the optimized power7 memcpy for forward copying.
2014-08-28PowerPC: optimized memmove for POWER7/PPC64Adhemerval Zanella11-2/+1037
This patch adds an optimized memmove optimization for POWER7/powerpc64. Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions.
2014-08-28PowerPC: memmove default implementation cleanupAdhemerval Zanella2-98/+7
This patch removes the powerpc specific logic in memmove and instead include default implementation with MEMCPY_OK_FOR_FWD_MEMMOVE defined. This lead in a increase performance, since the constraints to use memcpy in powerpc code are too restrictive and memcpy can be used for any forward memmove. This is a backport of d6f68bbef4427850c2901728a1d13efc0e687297.
2014-08-28PowerPC: strcat optimization for PPC64/POWER7Vidya Ranganathan7-4/+118
This patch adds an ifunc power7 strcat symbol that uses the logic on sysdeps/powerpc/strcat.c but call power7 strlen/strcpy symbols instead of default ones. This is a backport of bc8ea38590070604006399e42469087e943fc8ec.
2014-08-28PowerPC: sync hwcap.h capabilitiesAdhemerval Zanella2-0/+7
Linux commit dd58a092c4202f2bd490adab7285b3ff77f8e467 added the PPC_FEATURE2_VEC_CRYPTO auvx capability to indicate whether to hardware supports vector crypto hardware instructions. This patch adds its definition to powerpc hwcap bits. This is a backport of db22400947e1c82153e5270d23fed53fc1e3a659.
2014-08-28PowerPC: Fix nearbyintl failure for few inputsRajalakshmi Srinivasaraghavan4-1/+23
This patch fixes few failures in nearbyintl() where the fraction part is close to 0.5.i The new tests added report few extra failures in nearbyint_downward and nearbyint_towardzero which is a known issue. Fixes #17031. This is a backport of 754c5a08aacb44895d1ab97c553ce424eb43f761.
2014-06-22posix_spawn_file_actions_addopen needs to copy the path argument (BZ 17048)Florian Weimer6-9/+54
POSIX requires that we make a copy, so we allocate a new string and free it in posix_spawn_file_actions_destroy. Reported by David Reid, Alex Gaynor, and Glyph Lefkowitz. This bug may have security implications. (cherry picked from commit 89e435f3559c53084498e9baad22172b64429362) Conflicts: NEWS
2014-06-11PowerPC: Optimized strcmp for PPC64/POWER7Vidya Ranganathan7-1/+329
Optimization is achieved on 8 byte aligned strings with double word comparison using cmpb instruction. On unaligned strings loop unrolling is applied for Power7 gain. It is a backport of e23d3d2690bf63207b1a47e83a94693daebbbfe5.
2014-06-06PowerPC: Fix optimized strncat strlen callAdhemerval Zanella2-1/+8
This patch fixes the optimized ppc64/power7 strncat strlen call for static build without ifunc enabled. The strlen symbol to call in such situation is just strlen, instead of __GI_strlen (since the __GI_ alias is just created for shared objects). It is a backport of ed36bfa18faf9be457575568e64b8409e46caa22.
2014-06-06PowerPC: Fix --disable-multi-arch buildsAdhemerval Zanella11-6/+31
This patch fixes some powerpc32 and powerpc64 builds with --disable-multi-arch option along with different --with-cpu=powerN. It cleanups the Implies directories by removing the multiarch folder for non multiarch config and also fixing two assembly implementations: powerpc64/power7/strncat.S that is calling the wrong strlen; and power8/fpu/s_isnan.S that misses the hidden_def and weak_alias directives. It is a backport of de21c33c068c8e39afb5711613a7c083c11ce6a1.
2014-06-03Fixed pthread_spin_lock on sparc32/64 (bug 16882)Guo Yixuan6-6/+126

2014-05-26PowerPC: Remove 64 bits instructions in PPC32 codeAdhemerval Zanella9-16/+28
This patch replaces the insrdi by insrwi in powerpc32 assembly. It is a backport of d298c41635ce7f2dc7c3eccc842fe3aa754c0c8e.
2014-05-22PowerPC: Fix memchr ifunc hidden symbol for PPC32Adhemerval Zanella3-10/+21
This patch fixes a similar issue to 736c304a1ab4cee36a2f3343f1698bc0abae4608, where for PPC32 if the symbol is defined as hidden (memchr) then compiler will create a local branc (symbol@local) and the linker will not create a required PLT call to make the ifunc work. It changes the default hidden symbol (__GI_memchr) to default memchr symbol for powerpc32 (__memchr_ppc32). Backport of 3d2badacf185fac740a2992240a817fb2ca325af.
2014-05-21aarch64: Merge __local_multiple_threads offset with memory referenceRichard Henderson2-5/+10
This also highlights that we'd been loading 64-bits instead of the proper 32-bits. Caught by the linker as a relocation error, since the variable happened to be unaligned for 64-bits. Cherry-pick of a6b3657be6bc5067aeec98d990f60765361c6557.
2014-05-19PowerPC: Fix multiarch hypotf PPC64 pathAdhemerval Zanella2-0/+5

2014-05-06PowerPC: strncpy/stpncpy optimization for PPC64/POWER7Vidya Ranganathan11-1/+610
The optimization is achieved by following techniques: > data alignment [gain from aligned memory access on read/write] > POWER7 gains performance with loop unrolling/unwinding [gain by reduction of branch penalty]. > zero padding done by calling optimized memset
2014-05-05PowerPC: ifunc improvement for internal callsAdhemerval Zanella8-26/+64
This patch changes de default symbol redirection for internal call of memcpy, memset, memchr, and strlen to the IFUNC resolved ones. The performance improvement is noticeable in algorithms that uses these symbols extensible, like the regex functions. This is a backport of 19c4bec0f43599eecc2f32de96ae179cd7d64053.
2014-05-04misc/sys/xattr.h: guard against linux uapi header inclusionSerge Hallyn1-0/+2
If the glibc xattr.h header is included after the uapi header, compilation fails due to an enum re-using a #define from the uapi header. Protect against this by guarding the define and enum inclusions against each other.
