* Allow for unpriviledged nested containersDJ Delorie2022-04-041-0/+5
| | | | | | | | | | | | | | | | | If the build itself is run in a container, we may not be able to fully set up a nested container for test-container testing. Notably is the mounting of /proc, since it's critical that it be mounted from within the same PID namespace as its users, and thus cannot be bind mounted from outside the container like other mounts. This patch defaults to using the parent's PID namespace instead of creating a new one, as this is more likely to be allowed. If the test needs an isolated PID namespace, it should add the "pidns" command to its init script. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* Add alloc_align attribute to memalign et alJonathan Wakely2021-10-211-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 4.9.0 added the alloc_align attribute to say that a function argument specifies the alignment of the returned pointer. Clang supports the attribute too. Using the attribute can allow a compiler to generate better code if it knows the returned pointer has a minimum alignment. See https://gcc.gnu.org/PR60092 for more details. GCC implicitly knows the semantics of aligned_alloc and posix_memalign, but not the obsolete memalign. As a result, GCC generates worse code when memalign is used, compared to aligned_alloc. Clang knows about aligned_alloc and memalign, but not posix_memalign. This change adds a new __attribute_alloc_align__ macro to <sys/cdefs.h> and then uses it on memalign (where it helps GCC) and aligned_alloc (where GCC and Clang already know the semantics, but it doesn't hurt) and xposix_memalign. It can't be used on posix_memalign because that doesn't return a pointer (the allocated pointer is returned via a void** parameter instead). Unlike the alloc_size attribute, alloc_align only allows a single argument. That means the new __attribute_alloc_align__ macro doesn't really need to be used with double parentheses to protect a comma between its arguments. For consistency with __attribute_alloc_size__ this patch defines it the same way, so that double parentheses are required.

* Add TEST_COMPARE_STRING_WIDE to support/check.hJoseph Myers2021-10-121-0/+6
| | | | | | | | | | | | | | | | | | | | | | | I'd like to be able to test narrow and wide string interfaces, with the narrow string tests using TEST_COMPARE_STRING and the wide string tests using something analogous (possibly generated using macros from a common test template for both the narrow and wide string tests where appropriate). Add such a TEST_COMPARE_STRING_WIDE, along with functions support_quote_blob_wide and support_test_compare_string_wide that it builds on. Those functions are built using macros from common templates shared by the narrow and wide string implementations, though I didn't do that for the tests of test functions. In support_quote_blob_wide, I chose to use the \x{} delimited escape sequence syntax proposed for C2X in N2785, rather than e.g. trying to generate the end of a string and the start of a new string when ambiguity would result from undelimited \x (when the next character after such an escape sequence is valid hex) or forcing an escape sequence to be used for the next character in the case of such ambiguity. Tested for x86_64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Linux filesystems might not fully support 64 bit timestamps [1], which make some Linux specific tests to fail when they check for the functionality.

* localedef: Add verbose messages for failure paths.Carlos O'Donell2020-04-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | During testing of localedef running in a minimal container there were several error cases which were hard to diagnose since they appeared as strerror (errno) values printed by the higher level functions. This change adds three new verbose messages for potential failure paths. The new messages give the user the opportunity to use -v and display additional information about why localedef might be failing. I found these messages useful myself while writing a localedef container test for --no-hard-links. Since the changes cleanup the code that handle codeset normalization we add tst-localedef-path-norm which contains many sub-tests to verify the correct expected normalization of codeset strings both when installing to default paths (the only time normalization is enabled) and installing to absolute paths. During the refactoring I created at least one buffer-overflow which valgrind caught, but these tests did not catch because the exec in the container had a very clean heap with zero-initialized memory. However, between valgrind and the tests the results are clean. The new tst-localedef-path-norm passes without regression on x86_64. Change-Id: I28b9f680711ff00252a2cb15625b774cc58ecb9d

* Fix alignment of TLS variables for tls variant TLS_TCB_AT_TP [BZ #23403]Stefan Liebler2019-02-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alignment of TLS variables is wrong if accessed from within a thread for architectures with tls variant TLS_TCB_AT_TP. For the main thread the static tls data is properly aligned. For other threads the alignment depends on the alignment of the thread pointer as the static tls data is located relative to this pointer. This patch adds this alignment for TLS_TCB_AT_TP variants in the same way as it is already done for TLS_DTV_AT_TP. The thread pointer is also already properly aligned if the user provides its own stack for the new thread. This patch extends the testcase nptl/tst-tls1.c in order to check the alignment of the tls variables and it adds a pthread_create invocation with a user provided stack. The test itself is migrated from test-skeleton.c to test-driver.c and the missing support functions xpthread_attr_setstack and xposix_memalign are added. ChangeLog: [BZ #23403] * nptl/allocatestack.c (allocate_stack): Align pointer pd for TLS_TCB_AT_TP tls variant. * nptl/tst-tls1.c: Migrate to support/test-driver.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | The test-container.c file assumes that ld.so is always named something like /elf/ld-linux-*.

This patch introduces the new global variable support_objdir_elf_ldso which contains the absolute path to the runtime linker used by the testsuite, e.g. OBJDIR_PATH/elf/ld-linux-x86-64.so.2. The check in test-container.c is now comparing against this path.

The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected.
