* nscd: Improved support for tracking startup failure in nscd service (BZ #16639)Siddhesh Poyarekar2014-03-035-37/+161
| | | | | | | | | | | | | | | | | | | | | | Currently, the nscd parent process parses commandline options and configuration, forks on startup and immediately exits with a success. If the child process encounters some error after this, it goes undetected and any services started up after it may have to repeatedly check to make sure that the nscd service did actually start up and is serving requests. To make this process more reliable, I have added a pipe between the parent and child process, through which the child process sends a notification to the parent informing it of its status. The parent waits for this status and once it receives it, exits with the corresponding exit code. So if the child service sends a success status (0), the parent exits with a success status. Similarly for error conditions, the child sends the non-zero status code, which the parent passes on as the exit code. This, along with setting the nscd service type to forking in its systemd configuration file, allows systemd to be certain that the nscd service is ready and is accepting connections.

* Add header and standard information to threads.texi.Carlos O'Donell2014-02-282-0/+15
| | | | | | | The glibc manual uses special annotations to include functions in the summary chapter. These annotations were missing from the functions in the threads chapter. This patch adds those special markers and in turn adds these functions to the summary chapter.
* Promote do_lookup_x:check_match to a full function.Carlos O'Donell2014-02-282-104/+129
| | | | | | | | | | | | | | | | | While it may be argued that nested functions make the resulting code easier to read, or worse to read the following two bugs make it difficult to debug: Bug 8300 - no local symbol information within nested or nesting procedures https://sourceware.org/bugzilla/show_bug.cgi?id=8300 Bug 53927 - wrong value for DW_AT_static_link http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53927 Until these are fixed I've made check_match a full function. After they are fixed we can resume arguing about the merits of nested functions on readability and maintenance.

* Fix ARM NAN fraction bits.Joey Ye2014-02-272-3/+8
| | | | | | | | | | | | | | | | | | Current ARM soft-float implementation is violating the RTABI (http://infocenter.arm.com/help/topic/com.arm.doc.ihi0043d/IHI0043D_rtabi.pdf) Section 4.1.1.1: When not otherwise specified by IEEE 754, the result on an invalid operation should be the quiet NaN bit pattern with only the most significant bit of the significand set, and all other significand bits zero. This patch fixes it by setting _FP_NANFRAC_* to zero. Ran make check test with -mfloat-abi=soft. No regression. * sysdeps/arm/soft-fp/sfp-machine.h (_FP_NANFRAC_S, _FP_NANFRAC_D) (_FP_NANFRAC_Q): Set to zero.

* Fix sign of input to bsloww1 (BZ #16623)Siddhesh Poyarekar2014-02-276-7/+205
| | | | | | | | In 84ba214c, I removed some redundant sign computations and in the process, I incorrectly got rid of a temporary variable, thus passing the absolute value of the input to bsloww1. This caused #16623. This fix undoes the incorrect change.
* Support expected failures in .test-result files.Joseph Myers2014-02-275-5/+29
| | | | | | | | | | | | | | | | | | | | | | | This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00195.html>, makes it possible for .test-result files for individual tests to contain XPASS and XFAIL rather than PASS and FAIL in cases where failure is expected. This replaces the marking of two individual tests with "-" to cause them to be expected at makefile level to fail; evaluate-test.sh will ensure it exits with status 0 for an expected failure. Tested x86_64. * scripts/evaluate-test.sh: Take new argument indicating whether failure is expected. * Makeconfig (evaluate-test): Pass argument to evaluate-test.sh indicating whether failure is expected. * conform/Makefile (test-xfail-run-conformtest): New variable. ($(objpfx)run-conformtest.out): Don't expect to fail at makefile level. * posix/Makefile (test-xfail-annexc): New variable. ($(objpfx)annexc.out): Don't expect to fail at makefile level.
* Consistently include Makeconfig after defining subdir.Joseph Myers2014-02-2662-76/+205
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I noted it was necessary to add includes of Makeconfig early in various subdirectory makefiles for the tests-special variable settings added by that patch to be conditional on configuration information. No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed.

* Simplify calloc implementation.Ondřej Bílka2014-02-262-109/+10
| | | | | | To make future improvements of allocator simpler we could for now calloc just call malloc and memset. With that we could omit a changes that would duplicate malloc changes anyway.
* BZ #16632: Change [_BSD/_SVID]_SOURCE warning.Carlos O'Donell2014-02-253-3/+12
| | | | | | | | | | | | | | | | | | Source packages that need to support both 2.19 and 2.20 will need to decide to use _BSD_SOURCE and _SVID_SOURCE vs. _DEFAULT_SOURCE. The difficulty in making that decision is that __GLIBC_MINOR__ is itself defined in features.h, but you want to set the feature test macros before including features.h. Therefore to ease the transition we should disable the warning if _DEFAULT_SOURCE is also defined. https://sourceware.org/ml/libc-alpha/2014-02/msg00666.html https://sourceware.org/glibc/wiki/Release/2.20#Packaging_Changes
* BZ #16613: Support TLS in audit libraries.Carlos O'Donell2014-02-259-3/+90
| | | | | | | | | | | This commit fixes a bug where the dynamic loader would crash when loading audit libraries, via LD_AUDIT, where those libraries used TLS. The dynamic loader was not considering that the audit libraries would use TLS and failed to bump the TLS generation counter leaving TLS usage inconsistent after loading the audit libraries. https://sourceware.org/ml/libc-alpha/2014-02/msg00569.html
* misc/sys/select.h (__FD_MASK): Avoid signed integer overflow.Florian Weimer2014-02-253-2/+7
| | | | | | | Shifting into the sign position is currently supported as a GCC extension, but explicitly subjected to future changes. Computation in the unsigned type followed by a cast to the signed type is a GCC extension that will be available forever.
* ARM: Add SystemTap probes to longjmp and setjmp.Will Newton2014-02-255-31/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the ARM port implements pointer encryption for jmpbufs, gdb needs a SystemTap probe point in longjmp to determine the target PC of a call to longjmp. This patch implements the probe point in longjmp and a similar probe point in setjmp. In order to have all the appropriate registers available to pass to the probe this reorders the layout of jmpbuf, putting the sp and lr registers at the start rather than the end, allowing them to be read and written sequentially. Tested on armv7, no new failures in the glibc testsuite and confirmed that this fixes the gdb.base/longjmp.exp failures in the gdb testsuite. ChangeLog: 2014-02-25 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S: Include stap-probe.h. (__longjmp): Restore sp and lr before restoring callee saved registers. Add longjmp and longjmp_target SystemTap probe point. * sysdeps/arm/bits/setjmp.h (__jmp_buf): Update comment. * sysdeps/arm/include/bits/setjmp.h (__JMP_BUF_SP): Define to zero to match jmpbuf layout. * sysdeps/arm/setjmp.S: Include stap-probe.h. (__sigsetjmp): Save sp and lr before saving callee saved registers. Add setjmp SystemTap probe point.

This is just adding $(evaluate-test) calls to all such rules, since tests with multiple commands were previously split into separate tests. Note that the tests the makefiles expect to fail (posix/annexc and conformtest) currently get FAIL listed in the .test-result file, rather than XFAIL; a subsequent patch will introduce a better XFAIL mechanism.

* Fix __ASSUME_RECVMMSG issues (bug 16610).Joseph Myers2014-02-2014-8/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the issues for accept4, __ASSUME_RECVMMSG is also confused about whether it relates to function availability or socketcall operation availability; this is now bug 16610. Nothing actually tests __ASSUME_RECVMMSG for function availability, but implicit in the definition in kernel-features.h is the idea that it makes sense when the syscall is available and socketcall is not being used. As with accept4, there are architectures where the syscall was added later than the socketcall operation, meaning that assuming glibc is built with recent enough kernel headers, it does not attempt to use socketcall for these operations and __ASSUME_RECVMMSG gets defined for kernels >= 2.6.33 even when the syscall was only added later. This patch splits the macro into separate macros like those used for accept4; having similar macro structure in both cases (and for sendmmsg once I've dealt with that) seems likely to be less confusing than having a different structure on the basis of nothing actually needing to assume the recvmmsg function works. Appropriate definitions are added for all architectures. Architecture-specific note: Tile's kernel-features.h says "TILE glibc support starts with 2.6.36", which is accurate in that 2.6.36 was the first kernel version with Tile support, and on that basis I've made that header define __ASSUME_RECVMMSG_SYSCALL unconditionally. However, Tile's configure.ac has arch_minimum_kernel=2.6.32. Since arch_minimum_kernel is meant to reflect only kernel.org kernel versions, I think that should change to 2.6.36. (If using glibc with kernel versions from before a port went in kernel.org, it's your responsibility to change arch_minimum_kernel in a local patch, and at the same time to adjust any __ASSUME_* definitions that may not be correct for your older kernel; for developing the official glibc it should only ever be necessary to consider what official kernel.org releases support.)

* Fix __ASSUME_ACCEPT4 issues (bug 16609).Joseph Myers2014-02-2016-23/+151

As previously noted, __ASSUME_ACCEPT4 is used in two ways: * In OS-independent code, to mean "accept4 can be assumed to work rather than fail with ENOSYS". It doesn't matter whether it's implemented with socketcall or a separate syscall. * In Linux-specific code, to mean "the socketcall multiplex syscall can be assumed to handle the accept4 operation. When used in Linux-specific code, it *never* refers to anything relating to the accept4 syscall, only to the socketcall multiplexer. This patch splits the macro into separate __ASSUME_ACCEPT4_SOCKETCALL, __ASSUME_ACCEPT4_SYSCALL and __ASSUME_ACCEPT4 to clarify the different cases involved. A macro __ASSUME_SOCKETCALL is added for convenience in writing logic relating to all socketcall architectures. In addition, to address the issue of architectures where socketcall support for accept4 was added before a separate syscall was added (and so the separate syscall should not be used unless known to be present or fallback to socketcall is available), a fourth macro __ASSUME_ACCEPT4_SYSCALL_WITH_SOCKETCALL is added to indicate that the syscall became available at the same time as socketcall support. This is then used in the relevant places in a conditional determining whether to undefine __NR_accept4 (the simple approach to avoiding the syscall's presence causing problems; I didn't try to implement runtime fallback from the syscall to socketcall). Architecture-specific note: alpha defined __ASSUME_ACCEPT4 for 2.6.33 and later, but actually the syscall was added for alpha in 3.2, so this patch uses the correct condition for __ASSUME_ACCEPT4_SYSCALL there. Tested x86_64, including that disassembly of the installed shared libraries is unchanged by this patch.

* Move tests of clog10 from libm-test.inc to auto-libm-test-in.Joseph Myers2014-02-196-164/+34006
| | | | | | | | | | | | | | | | | | This patch moves tests of clog10 to auto-libm-test-in. Note that this means gen-auto-libm-tests will now depend on the recent MPC 1.0.2 release which added a fix for a bug that made gen-auto-libm-tests hang for clog10. (It still can't conveniently be used for cacos cacosh casin casinh catan catanh csin csinh because of extreme slowness of those functions for special cases in MPC; at least some slow cases of csin / csinh are fixed in MPC trunk, but not in a release.)

* Move tests of fma from libm-test.inc to auto-libm-test-in.Joseph Myers2014-02-185-901/+15468
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves tests of fma to auto-libm-test-in, adding the required support to gen-auto-libm-tests. Because fma can have exact zero results depending on the rounding mode, results of fma cannot always be determined from a single value computed in higher precision with a sticky bit. Thus, this patch adds support for recomputing results with the original MPFR/MPC function in the case where an exact zero is involved. (This also affects some results for cpow; when we start testing cpow in all rounding modes, I think it will be most appropriate to make those tests use IGNORE_ZERO_INF_SIGN, since ISO C does not attempt to determine signs of zero results, or special caes in general, for cpow, and I think signs of zero for cpow are beyond the scope of glibc's accuracy goals.) Simply treating the existing test inputs for fma like those for other functions (i.e., as representing the given value rounded up or down to any of the supported floating-point formats) increases the size of auto-libm-test-out by about 16MB (i.e., about half the file is fma test data). While rounded versions of tests are perfectly reasonable test inputs for fma, in this case having them seems excessive, so this patch allows functions to specify in gen-auto-libm-tests that the given test inputs are only to be interpreted exactly, not as corresponding to values rounded up and down. This reduces the size of the generated test data for fma to a more reasonable 2MB. A consequence of this patch is that fma is now tested for correct presence or absence of "inexact" exceptions, where previously this wasn't tested because I didn't want to try to add that test coverage manually to all the existing tests. As far as I know, the existing fma implementations are already correct in this regard. This patch provides the first cases where the gen-auto-libm-tests support for distinguishing before-rounding/after-rounding underflow actually produces separate entries in auto-libm-test-out (for functions without exactly determined results, the affected cases are all considered underflow-optional, so this only affects functions like fma with exactly determined results). I didn't see any signs of problems with this logic in the output.
