* locale: Do not define lang_ab for tcy_IN and bhb_INKhem Raj2015-07-213-2/+8
| | | | | | | | | After renaming localedef now complains and build fails LC_ADDRESS: field `lang_ab' must not be defined earlier the names were similar to lang_ab definitions 'tu' or 'bh' but after rename they are not.

* sparc: fix sigaction for 32bit builds [BZ #18694]Mike Frysinger2015-07-203-1/+16
| | | | | | | | | | | Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction struct to pass conform tests, but it ended up also changing the ABI for 32 bit builds. For 64 bit builds, changing the long to two ints works, but for 32 bit builds, it inserts 4 extra bytes. This leads to many packages randomly failing like bash that spews things like: configure: line 471: wait_for: No record of process 0 Bracket the new member by a wordsize check to fix the ABI for 32bit.
* Remove Linuxism from tst-tls-atexitSiddhesh Poyarekar2015-07-213-43/+64
| | | | | | | | | | | | | | | | | | | | | | The tst-tls-atexit test case searches for its module in /proc/PID/maps to verify that it is unloaded, which is a Linux-specific test. This patch makes the test generic by looking for the library in the link map list in the _r_debug structure. Verified that the test continues to succeed on x86_64. There is a bug in the test case where it calls dlclose once again, which is actually incorrect but still manages to unload the DSO thanks to an existing bug in __tls_call_dtors. This will be fixed in a later patch which also fixes up the __cxa_thread_atexit_impl implementation. I have added a FIXME comment to that call momentarily, which I will remove when I fix the problem. * stdlib/tst-tls-atexit-lib.c (do_foo): Rename to reg_dtor. * stdlib/tst-tls-atexit.c: (is_loaded): New function. (spawn_thread): New function. (load): Rename to reg_dtor_and_close. Move dlopen to... (do_test): ... here. Use IS_LOADED to test for its availability.

* tst-leaks: raise timeout to 5 secondsChris Metcalf2015-07-202-0/+5
| | | | | This test takes about 2.3 seconds on my tilegx system, and so times out. Bump it up to 5 seconds instead.
* Add si_addr_bnd to _sigfault in x86 struct siginfoH.J. Lu2015-07-203-1/+16
| | | | | | | | | | | | | | | | | | | | | | 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.

* libio: Fix fmemopen 'w' mode with provided bufferAdhemerval Zanella2015-07-163-5/+12
| | | | | | | | | | | | | 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.
* powerpc: strstr optimizationRajalakshmi Srinivasaraghavan2015-07-167-1/+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.
* hppa/ia64: _dl_unmap: make it hiddenMike Frysinger2015-07-165-4/+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.
* hppa/ia64: _dl_symbol_address: add PLT bypass for rtldMike Frysinger2015-07-164-0/+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.

* Set NODELETE flag when opening already open objects with RTLD_NODELETESiddhesh Poyarekar2015-07-166-8/+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.

* Remove unnecessary mutex locks from tst-tls-atexit test caseSiddhesh Poyarekar2015-07-102-3/+3

* Clean up semaphore EINTR handling after Linux futex docs clarification.Torvald Riegel2015-07-102-30/+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.
* Add and use new glibc-internal futex API.Torvald Riegel2015-07-1040-492/+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.

* Improve bndmov encoding with zero displacementH.J. Lu2015-07-092-0/+13
| | | | | | | | | | If x86-64 assembler doesn't support MPX, we encode bndmov instruction by hand. When displacement is zero, assembler generates shorter encoding.

* [AArch64][BZ 18648] change greg_t definition in ucontext.hSzabolcs Nagy2015-07-093-8/+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.
