* BZ #16613: Support TLS in audit libraries.Carlos O'Donell2014-02-251-1/+8
| | | | | | | | | | | 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
* Generate .test-result files for tests with special rules.Joseph Myers2014-02-211-21/+42

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.

* Split up rules for tests that compare output with baselines.Joseph Myers2014-02-141-42/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch splits makefile rules that generate a file then run cmp to check the contents of that file into separate rules to generate and compare the file. This simplifies making those tests generate PASS / FAIL results, by removing the need to insert && between commands in the test so that a $(evaluate-test) call is reached. It also avoids the oddity of the .out file being an intermediate file rather than the final result generated, as noted for some of these tests in <https://sourceware.org/ml/libc-alpha/2012-10/msg00894.html>. In many cases, the rule to run the program was no longer needed because the default rules for running test programs on the host to generate a .out file sufficed. (I'm not asserting the commands run after this patch are *exactly* the same as before, simply that the rules did nothing special that appeared deliberate or relevant to anything about what the tests were testing. In cases where the rules redirected stderr as well as stdout, I left the existing rule's redirection in place to avoid changing what gets compared with the expected results.) It's clear there is a lot in common between the various -cmp.out rules and it might be possible in future to refactor them into more generic support for the case of comparing test output against a baseline. (Some baselines are *.exp, some *.expect, some directly embedded in the makefiles, and nptl/tst-cleanupx0.expect appears unused.) Tested x86_64. * elf/Makefile ($(objpfx)order.out): Remove rule.

* Make ABI tests generate .out files.Joseph Myers2014-02-121-1/+1
| | | | | | | | | | | | | | | | | | | If you rerun "make check" in a tree where some tests have already been run, it will rerun ABI tests because those do not create an output file. This patch changes those tests to create .out files so they only get rerun if the dependencies (on the ABI baselines and the generated .symlist files) indicate they should be rerun. Tested x86_64. * Makerules (check-abi-%): Change target to $(objpfx)check-abi-%.out. (check-abi target): Update dependencies. (check-abi-pattern variable): Redirect output of diff to $@. (check-abi variable): Likewise. * elf/Makefile (check-abi): Update dependencies.

* BZ #15754: Fix test case for ARM.Carlos O'Donell2013-09-231-0/+3
| | | | | | | Statically built binaries use __pointer_chk_guard_local, while dynamically built binaries use __pointer_chk_guard. Provide the right definition depending on the test case we are building.
* BZ #15754: CVE-2013-4788Carlos O'Donell2013-09-231-2/+7
| | | | | | | | | | | | The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.

* Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar2013-05-291-2/+4
| | | | | | | | | Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users.

* rtld: limit self loading check to normal mode onlyDmitry V. Levin2012-09-191-1/+4
| | | | | | | | | Commit glibc-2.14~10 disallowed rtld self loading to avoid a segfault that used to happen when rtld was loading itself in normal mode. Unfortunately, that commit disallowed all modes of self loading, including those that used to work before. This change limits the check for self loading to normal mode only, so that instruments like ldd could handle rtld properly.

* New ld.so argument --inhibit-ldcache to disable ld.so.cache lookupSiddhesh Poyarekar2012-04-111-1/+2
| | | | | | | | | | | It may sometimes be desirable to make the dynamic linker only pick up libraries from the library path and rpath and not look at the ld.so.cache that ldconfig generates. An example of such a use case is the glibc testsuite where the dynamic linker must not be influenced by any external paths or caches. This change adds a new option --inhibit-ldcache that when used, tells the dynamic linker to not use ld.so.cache even if it is available.
