2015-07-20Add si_addr_bnd to _sigfault in x86 struct siginfohjl/pr18696H.J. Lu1-0/+7
X86 struct siginfo in kernel 3.19 has been changed by commit ee1b58d36aa1b5a79eaba11f5c3633c88231da83 Author: Qiaowei Ren <qiaowei.ren@intel.com> Date: Fri Nov 14 07:18:19 2014 -0800 mpx: Extend siginfo structure to include bound violation information This patch adds new fields about bound violation into siginfo structure. si_lower and si_upper are respectively lower bound and upper bound when bound violation is caused. This patch updates x86 struct siginfo to enable GDB with MPX support. [BZ #18696] * sysdeps/unix/sysv/linux/x86/bits/siginfo.h (_sigfault): Add si_addr_bnd. (si_lower): New. (si_upper): Likewise.

If 'w' mode is used with a provided buffer the fmemopen will try to find the first null byte to set as maximum internal stream size. It should be done only for append mode ('a'). Kudos for Stefan Liebler for finding this error on s390-32. * libio/fmemopen.c (__fmemopen): Fix 'w' openmode with provided buffer. * stdio-common/tst-fmemopen2.c (do_test_with_buffer): Fix typo and fail output information.
2015-07-16powerpc: strstr optimizationRajalakshmi Srinivasaraghavan7-1/+636
This patch optimizes strstr function for power >= 7 systems. Performance gain is obtained using aligned memory access and usage of cmpb instruction for quicker comparison. The average improvement of this optimization is ~40%. Tested on ppc64 and ppc64le. 2015-07-16 Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com> * sysdeps/powerpc/powerpc64/multiarch/Makefile: Add strstr(). * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c: Likewise. * sysdeps/powerpc/powerpc64/power7/strstr.S: New File. * sysdeps/powerpc/powerpc64/multiarch/strstr-power7.S: New File. * sysdeps/powerpc/powerpc64/multiarch/strstr-ppc64.c: New File. * sysdeps/powerpc/powerpc64/multiarch/strstr.c: New File.
2015-07-16hppa/ia64: _dl_unmap: make it hiddenMike Frysinger5-4/+11
This symbol is only used by DL_UNMAP which in turn is only used by _dl_close_worker in dl-close.c, and _dl_close_worker itself is marked hidden as it is only used by the ldso. That means _dl_unmap should be marked hidden. Without this, the elf/check-localplt test fails.
2015-07-16hppa/ia64: _dl_symbol_address: add PLT bypass for rtldMike Frysinger4-0/+10
This symbol is defined in the ldso, and is used both there and libc.so. There is no hidden symbol for it though which leads to relocations in the ldso and the elf/check-localplt test failing. Add a hidden def for rtld to fix all of that. This function/file is only used by hppa & ia64, so no testing is needed for other arches.

2015-07-16Set NODELETE flag when opening already open objects with RTLD_NODELETESiddhesh Poyarekar6-8/+106
The DF_1_NODELETE flag is set too late when opening a DSO, due to which, if a DSO is already open, subsequently opening it with RTLD_NODELETE fails to set the DF_1_NODELETE flag. This patch fixes this by setting the flag immediately after bumping the opencount. Verified on x86_64.

On tile (and any other machine with no FP exceptions) the feenable_test() function will generate a "function defined but not used" warning because all of the callers are commented out. We already were ifdef'ing out the body of the function, so instead just ifdef out the entire function if FE_ALL_EXCEPT == 0.

2015-07-10Clean up semaphore EINTR handling after Linux futex docs clarification.Torvald Riegel2-30/+12
The Linux kernel futex documentation now states that since Linux 2.6.22, FUTEX_WAIT does return EINTR only when interrupted by a signal, and not spuriously anymore. We only support more recent kernels, so clean up EINTR handling in the semaphore and update the comments.
2015-07-10Add and use new glibc-internal futex API.Torvald Riegel40-492/+963
This adds new functions for futex operations, starting with wait, abstimed_wait, reltimed_wait, wake. They add documentation and error checking according to the current draft of the Linux kernel futex manpage. Waiting with absolute or relative timeouts is split into separate functions. This allows for removing a few cases of code duplication in pthreads code, which uses absolute timeouts; also, it allows us to put platform-specific code to go from an absolute to a relative timeout into the platform-specific futex abstractions.. Futex operations that can be canceled are also split out into separate functions suffixed by "_cancelable". There are separate versions for both Linux and NaCl; while they currently differ only slightly, my expectation is that the separate versions of lowlevellock-futex.h will eventually be merged into futex-internal.h when we get to move the lll_ functions over to the new futex API.

2015-07-09Improve bndmov encoding with zero displacementH.J. Lu2-0/+13
If x86-64 assembler doesn't support MPX, we encode bndmov instruction by hand. When displacement is zero, assembler generates shorter encoding.

2015-07-09[AArch64][BZ 18648] change greg_t definition in ucontext.hSzabolcs Nagy3-8/+12
This is an ABI breaking change, but typedef int greg_t; is not a useful definition on aarch64. greg_t is usually used for defining gregset_t which is used in mcontext_t. The general registers in mcontext_t can only be accessed by target specific code and on aarch64 greg_t is not needed for that so this change is not supposed to break existing code, just fix the definition. [BZ #18648] * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h (greg_t): Change the definition to elf_greg_t. (Added another BZ entry that was missed in the previous commit).

Kernel uses int pr_uid, pr_gid, but glibc used unsigned short. This is an ABI breaking change, but the size and alignment of the struct and the layout of other members is not changed and there is no known usage of pr_uid and pr_gid so it is expected to be safe.

This patch added a new fmemopen version, for glibc 2.22, that aims to be POSIX complaint. It fixes some long-stading glibc fmemopen issues, such as: * it changes the way fseek with SEEK_END works on fmemopen to seek relative to buffer size instead of first '\0'. This is default mode and 'b' opening mode does not change internal behavior (bz#6544). * fix apending opening mode to use as start position either first null byte of len specified in function call (bz#13152 and #13151). * remove binary option 'b' and internal different handling (bz#12836) * fix seek/SEE_END with negative values (bz#14292).

Both of "_IO_UNBUFFERED" and "_IO_LINE_BUF" are the bit flags, but I find there are some codes looks like "_IO_LINE_BUF+_IO_UNBUFFERED", while some codes are "_IO_LINE_BUF|_IO_UNBUFFERED". I think the former is not good, even though the final result is same.
