2014-07-02malloc/obstack: Merge from gnulibWill Newton
Merge the latest version of the obstack.c and obstack.h files from gnulib. The majority of this change is coding style and cosmetic comment changes but it also fixes a -Wundef warning in the build as a side effect. 2014-07-02 Will Newton <will.newton@linaro.org> * malloc/obstack.c: Merge from gnulib master. [HAVE_CONFIG_H]: Remove conditional code. [!_LIBC]: Include config.h. [!ELIDE_CODE]: Don't include inttypes.h, include stdint.h unconditionally. (print_and_abort): Mark as _Noreturn. (_obstack_allocated_p): Mark as __attribute_pure__. (obstack_free): Rename to __obstack_free. [!__attribute__]: Remove conditional code. * malloc/obstack.h: Merge from gnulib master. [__cplusplus]: Move conditional down. [!__attribute_pure__]: Define __attribute_pure__ here if it is not already defined. (_obstack_memory_used): Mark as __attribute_pure__. [!__obstack_free]: Define as obstack_free. [__GNUC__]: Remove check for ancient NeXT gcc.
2014-06-19malloc/malloc.c: Avoid calling sbrk unnecessarily with zeroWill Newton
Due to my bad review suggestion for the fix for BZ #15089 a check was removed from systrim to prevent sbrk being called with a zero argument. Add the check back to avoid this useless work. ChangeLog: 2014-06-19 Will Newton <will.newton@linaro.org> * malloc/malloc.c (systrim): If extra is zero then return early.
2014-06-06Don't require test wrappers to preserve environment variables, use more ↵Joseph Myers
consistent environment. One wart in the original support for test wrappers for cross testing, as noted in <https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the requirement for test wrappers to pass a poorly-defined set of environment variables from the build system to the system running the glibc under test. Although some variables are passed explicitly via $(test-wrapper-env), including LD_* variables that simply can't be passed implicitly because of the side effects they'd have on the build system's dynamic linker, others are passed implicitly, including variables such as GCONV_PATH and LOCPATH that could potentially affect the build system's libc (so effectively relying on any such effects not breaking the wrappers). In addition, the code in cross-test-ssh.sh for preserving environment variables is fragile (it depends on how bash formats a list of exported variables, and could well break for multi-line variable definitions where the contents contain things looking like other variable definitions). This patch moves to explicitly passing environment variables via $(test-wrapper-env). Makefile variables that previously used $(test-wrapper) are split up into -before-env and -after-env parts that can be passed separately to the various .sh files used in testing, so those files can then insert environment settings between the two parts. The common default environment settings in make-test-out are made into a separate makefile variable that can also be passed to scripts, rather than many scripts duplicating those settings (for testing an installed glibc, it is desirable to have the GCONV_PATH setting on just one place, so just that one place needs to support it pointing to an installed sysroot instead of the build tree). The default settings are included in the variables such as $(test-program-prefix), so that if tests do not need any non-default settings they can continue to use single variables rather than the split-up variables. Although this patch cleans up LC_ALL=C settings (that being part of the common defaults), various LANG=C and LANGUAGE=C settings remain. Those are generally unnecessary and I propose a subsequent cleanup to remove them. LC_ALL takes precedence over LANG, and while LANGUAGE takes precedence over LC_ALL, it only does so for settings other than LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C locale, and anything that gets LC_ALL=C does not need the other settings. While preparing this patch I noticed some tests with .sh files that appeared to do nothing beyond what the generic makefile support for tests can do (localedata/tst-wctype.sh - the makefiles support -ENV variables and .input files - and localedata/tst-mbswcs.sh - just runs five tests that could be run individually from the makefile). So I propose another subsequent cleanup to move those to using the generic support instead of special .sh files.

2014-05-30Remove mi_arena nested function.Ondřej Bílka

2014-05-26Remove nested function mi_arena from malloc_info.Carlos O'Donell
The nested function mi_arena was removed from malloc_info and made into a non-nested static inline function of the same name with the correct set of arguments passed from malloc_info. This enables building glibc with compilers that don't support nested functions. Future work on malloc_info should remove these functions entirely to support JSON format output. Therefore we do the minimum required to remove the nested function.
2014-05-16Use existing makefile variables for dependencies on glibc libraries.Joseph Myers
glibc's Makeconfig defines some variables such as $(libm) and $(libdl) for linking with libraries built by glibc, and nptl/Makeconfig (included by the toplevel Makeconfig) defines others such as $(shared-thread-library). In some places glibc's Makefiles use those variables when linking against the relevant libraries, but in other places they hardcode the location of the libraries in the build tree. This patch cleans up various places to use the variables that already exist (in the case of libm, replacing several duplicate definitions of a $(link-libm) variable in subdirectory Makefiles). (It's not necessarily exactly equivalent to what the existing code does - in particular, $(shared-thread-library) includes libpthread_nonshared, but is replacing places that just referred to libpthread.so. But I think that change is desirable on the general principle of linking things as close as possible to the way in which they would be linked with an installed library, unless there is a clear reason not to do so.) To support running tests with an installed copy of glibc without needing the full build tree from when that copy was built, I think it will be useful to use such variables more generally and systematically - every time the rules for building a test refer to some file from the build tree that's also installed by glibc, use a makefile variable so that the installed-testing case can point those variables to installed copies of the files. This patch just deals with straightforward cases where such variables already exist. It's quite possible some uses of $(shared-thread-library) should actually be a new $(thread-library) variable that's set appropriately in the --disable-shared case, if those uses would in fact work without shared libraries. I didn't change the status quo that those cases hardcode use of a shared library whether or not it's actually needed (but other uses such as $(libm) and $(libdl) would now get the static library if the shared library isn't built, when some previously hardcoded use of the shared library - if they actually need shared libraries, the test itself needs an enable-shared conditional anyway).

2014-03-06Enumerate tests with special rules in tests-special variable.Joseph Myers
This patch is a revised and updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>. In order to generate overall summaries of the results of all tests in the glibc testsuite, we need to identify and concatenate the files with the results of individual tests. Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this. However, the normal glibc approach is explicit enumeration of the expected set of files with a given property, rather than all files matching some pattern like that. Furthermore, we would like to be able to mark tests as UNRESOLVED if the file with their results is for some reason missing, and in future we would like to be able to mark tests as UNSUPPORTED if they are disabled for a particular configuration (rather than simply having them missing from the list of tests as at present). Such handling of tests that were not run or did not record results requires an explicit enumeration of tests. For the tests following the default makefile rules, $(tests) (and $(xtests)) provides such an enumeration. Others, however, are added directly as dependencies of the "tests" and "xtests" makefile targets. This patch changes the makefiles to put them in variables tests-special and xtests-special, with appropriate dependencies on the tests listed there then being added centrally. Those variables are used in Rules and so need to be set before Rules is included in a subdirectory makefile, which is often earlier in the makefile than the dependencies were present before. We previously discussed the question of where to include Rules; see the question at <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a discussion in <https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why Rules is included early rather than late in subdirectory makefiles. It was necessary to avoid an indirection through the check-abi target and get the check-abi-* targets for individual libraries into the tests-special variable. The intl/ test $(objpfx)tst-gettext.out, previously built only because of dependencies from other tests, was also added to tests-special for the same reason. The entries in tests-special are the full makefile targets, complete with $(objpfx) and .out. If a future change causes tests to be named consistently with a .out suffix, this can be changed to include just the path relative to $(objpfx), without .out. Tested x86_64, including that the same set of files is generated in the build directory by a build and testsuite run both before and after the patch (except for changes to the elf/tst-null-argv.debug.out.<number> file name), and a build with run-built-tests=no to verify there aren't any more obvious instances of the issue Marcus Shawcroft reported with a previous version in <https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>. * Makefile (tests): Change dependencies to ....

2014-02-28Fix fallout from Joseph's untested Makeconfig change.Roland McGrath
2014-02-26Consistently include Makeconfig after defining subdir.Joseph Myers
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.

2014-02-21Generate .test-result files for tests with special rules.Joseph Myers
This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html> now proposed for inclusion in glibc, extends the generation of PASS and FAIL status in .test-result files for individual tests to cover tests with their own custom makefile rules. 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.

2013-12-24Fix race in free() of fastbin chunk: BZ #15073Maxim Kuvyrkov
Perform sanity check only if we have_lock. Due to lockless nature of fastbins we need to be careful derefencing pointers to fastbin entries (chunksize(old) in this case) in multithreaded environments. The fix is to add have_lock to the if-condition checks. The rest of the patch only makes code more readable. * malloc/malloc.c (_int_free): Perform sanity check only if we have_lock.

2013-11-21Use __glibc_block in public headers.Meador Inge
As detailed in PR11157, the use of '__block' is known to interfere with keywords in some environments, such as the Clang -fblocks extension. Recently a similar issue was raised concerning the use of '__unused' and a '__glibc' prefix was proposed to create a glibc implementation namespace for these sorts of issues [1]. This patches takes that approach. [1] https://sourceware.org/ml/libc-alpha/2012-02/msg00047.html [2] http://lists.debian.org/debian-glibc/2013/11/msg00020.html

2013-10-30malloc: Fix for infinite loop in memalign/posix_memalign.Will Newton
A very large alignment argument passed to mealign/posix_memalign causes _int_memalign to enter an infinite loop. Limit the maximum alignment value to the maximum representable power of two to prevent this from happening. Changelog: 2013-10-30 Will Newton <will.newton@linaro.org> [BZ #16038] * malloc/hooks.c (memalign_check): Limit alignment to the maximum representable power of two. * malloc/malloc.c (__libc_memalign): Likewise. * malloc/tst-memalign.c (do_test): Add test for very large alignment values. * malloc/tst-posix_memalign.c (do_test): Likewise.

2013-10-10malloc/hooks.c: Correct check for overflow in memalign_check.Will Newton
A large value of bytes passed to memalign_check can cause an integer overflow in _int_memalign and heap corruption. This issue can be exposed by running tst-memalign with MALLOC_CHECK_=3. ChangeLog: 2013-10-10 Will Newton <will.newton@linaro.org> * malloc/hooks.c (memalign_check): Ensure the value of bytes passed to _int_memalign does not overflow.
