* Modify elf/tst-audit9.c to use test-skeleton.cArjun Shankar2015-07-152-1/+12
| | | | | | | | | | | | | | | This test was skipped by the use-test-skeleton conversion script [29955b5d] because the definition of `main' did not begin according to the GNU formatting style that the script assumed. ChangeLog: 2015-07-09 Arjun Shankar <arjun.is@lostca.se> * elf/tst-audit9.c (main): Converted to ... (do_test): ... this. (TEST_FUNCTION): New macro. Include test-skeleton.c.
* tst-tzset: raise timeout to 5 secondsMike Frysinger2015-07-152-0/+5
| | | | | This test is reliably taking 2.3 seconds on my system, and the default is 2 seconds, so it always times out. Bump it up to 5 seconds instead.
* i686: Mark stdlib/tst-makecontext as XFAIL.Stefan Liebler2015-07-152-0/+11
| | | | | | | | | | | The testcase stdlib/tst-makecontext fails on i686 because _Unwind_Backtrace from libgcc produces a segmentation fault if it was called within a context created by makecontext. See Bug 18635. ChangeLog: * sysdeps/i386/i686/Makefile (test-xfail-tst-makecontext): New variable.
* S390: Regenerate ULPsStefan Liebler2015-07-152-28/+32

* math/test-fenvinline: avoid compiler warningChris Metcalf2015-07-102-2/+7
| | | | | | | | 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.
* 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. This patch improves bndmov encoding with zero displacement so that ld.so is identical when using assemblers with and without MPX support. * sysdeps/x86_64/dl-trampoline.S (_dl_runtime_resolve): Improve bndmov encoding with zero displacement.

* [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. [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).
* [AArch64][BZ 18400] fix elf_prpsinfo in procfs.hSzabolcs Nagy2015-07-092-2/+7
| | | | | | | | | | | | | 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. [BZ #18400] * sysdeps/unix/sysv/linux/aarch64/sys/procfs.h (struct elf_prpsinfo): Fix pr_uid and pr_gid members.

* libio: fmemopen rewrite to POSIX complianceAdhemerval Zanella2015-07-0837-114/+703

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). A compatibility symbol is provided to with old behavior for older symbols version (2.2.5). * include/stdio.h (fmemopen): Remove hidden prototype.

* Use "|" instead of "+" when combine the _IO_LINE_BUF and _IO_UNBUFFERED flagsFeng Gao2015-07-084-7/+14
| | | | | | | | 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.

| | | | | | Mark all the functions that don't handle NULL pointers as __nonnull. POSIX does not require either behavior, so the prototypes should match the reality of the codebase.
* Fix ruserok scalability with large ~/.rhosts file.Carlos O'Donell2015-07-083-37/+55
| | | | | | | | | | | | | | | | Fixes bug 18557. The ruserok API does hosts checks first while it walks the user's ~/.rhosts file. This results in lots of DNS queries that could have been skipped if we short-circuit test the user portion first to see if would have had a failed match. This supports configurations where rlogin is used on internal secure networks with large numbers of users and machines. The Red Hat QE team did extensive testing on various rlogin combinations to validate this change, and in fact we found a defect in the first version which is fixed in this version.
* Add forced deletion support to _dl_close_workerPavel Kopyl2015-07-0711-19/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://sourceware.org/bugzilla/show_bug.cgi?id=17833 I've a shared library that contains both undefined and unique symbols. Then I try to call the following sequence of dlopen: 1. dlopen("./libfoo.so", RTLD_NOW) 2. dlopen("./libfoo.so", RTLD_LAZY | RTLD_GLOBAL) First dlopen call terminates with error because of undefined symbols, but STB_GNU_UNIQUE ones set DF_1_NODELETE flag and hence block library in the memory. The library goes into inconsistent state as several structures remain uninitialized. For instance, relocations for GOT table were not performed. By the time of second dlopen call this library looks like as it would be fully initialized but this is not true: any call through incorrect GOT table leads to segmentation fault. On some systems this inconsistency triggers assertions in the dynamic linker. This patch adds a parameter to _dl_close_worker to implement forced object deletion in case of dlopen() failure: 1. Clears DF_1_NODELETE bit if forced, to allow library to be removed from memory. 2. For each unique symbol that is defined in this object clears appropriate entry in _ns_unique_sym_table.

* S390: Fix "backtrace() returns infinitely deep stack frames with ↵Stefan Liebler2015-07-076-5/+78

On s390/s390x backtrace(buffer, size) returns the series of called functions until "makecontext_ret" and additional entries (up to "size") with "makecontext_ret". GDB-backtrace is also warning: "Backtrace stopped: previous frame identical to this frame (corrupt stack?)" To reproduce this scenario you have to setup a new context with makecontext() and activate it with setcontext(). See e.g. cf() function in testcase stdlib/tst-makecontext.c. Or see bug in libgo "Bug 66303 - runtime.Caller() returns infinitely deep stack frames on s390x " (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66303). This patch omits the cfi_startproc/cfi_endproc directives in ENTRY/END macro of __makecontext_ret. Thus no frame information is generated in .eh_frame and backtrace stops after __makecontext_ret. There is also no .eh_frame info for _start or thread_start functions.

When this happens in C code, the compiler can potentially detect this, leading to warnings in application code when those string functions are inlined. Perform those operations in the assembly code instead of the C code to fix this.
