2024-12-13or1k: Update libm-test-ulpsStafford Horne1-0/+27
Pick up new functions cospi, "Imaginary part of csin", exp10m1, exp2m1, log10p1, log2p1, sinpi and tanpi.
2024-12-13nptl: Add <thread_pointer.h> for or1kMichael Jeanson1-0/+30
This will be required by the rseq extensible ABI implementation on all Linux architectures exposing the '__rseq_size' and '__rseq_offset' symbols to set the initial value of the 'cpu_id' field which can be used by applications to test if rseq is available and registered. As long as the symbols are exposed it is valid for an application to perform this test even if rseq is not yet implemented in libc for this architecture. Compile tested with build-many-glibcs.py but I don't have access to any hardware to run the tests.

2024-12-12Implement C23 atan2piJoseph Myers51-2/+14869
C23 adds various <math.h> function families originally defined in TS 18661-4. Add the atan2pi functions (atan2(y,x)/pi). Tested for x86_64 and x86, and with build-many-glibcs.py.
2024-12-12Clear CXX and TEST_CXX if C++ link test failsH.J. Lu2-12/+2
Since the C++ compiler is used only for testing, use TEST_CXX as the C++ compiler if available. If C++ link test fails, clear both CXX and TEST_CXX so that the C++ compiler isn't used for glibc build nor test. Tested for m68k-linux-gnu-coldfire build and native build on x86-64.

2024-12-11powerpc: Use correct procedure call standard for getrandom vDSO call (bug 32440)Florian Weimer3-6/+49
A plain indirect function call does not work on POWER because success and failure are signaled through a flag register, and not via the usual Linux negative return value convention. This has potential security impact, in two ways: the return value could be out of bounds (EAGAIN is 11 on powerpc6le), and no random bytes have been written despite the non-error return value. Fixes commit 461cab1de747f3842f27a5d24977d78d561d45f9 ("linux: Add support for getrandom vDSO"). Reported-by: Ján Stanček <jstancek@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2024-12-11Add TEST_CC and TEST_CXX supportH.J. Lu8-136/+682
Support testing glibc build with a different C compiler or a different C++ compiler with $ ../glibc-VERSION/configure TEST_CC="gcc-6.4.1" TEST_CXX="g++-6.4.1" 1. Add LIBC_TRY_CC_AND_TEST_CC_OPTION, LIBC_TRY_CC_AND_TEST_CC_COMMAND and LIBC_TRY_CC_AND_TEST_LINK to test both CC and TEST_CC. 2. Add check and xcheck targets to Makefile.in and override build compiler options with ones from TEST_CC and TEST_CXX. Tested on Fedora 41/x86-64: 1. Building with GCC 14.2.1 and testing with GCC 6.4.1 and GCC 11.2.1. 2. Building with GCC 15 and testing with GCC 6.4.1. Support for GCC versions older than GCC 6.2 may need to change the test sources. Other targets may need to update configure.ac under sysdeps and modify Makefile.in to override target build compiler options. Signed-off-by: H.J.

2024-12-11malloc: Add tcache path for callocWangyang Guo2-38/+132
This commit add tcache support in calloc() which can largely improve the performance of small size allocation, especially in multi-thread scenario. tcache_available() and tcache_try_malloc() are split out as a helper function for better reusing the code. Also fix tst-safe-linking failure after enabling tcache. In previous, calloc() is used as a way to by-pass tcache in memory allocation and trigger safe-linking check in fastbins path. With tcache enabled, it needs extra workarounds to bypass tcache.

2024-12-10malloc: add indirection for malloc(-like) functions in tests [BZ #32366]Sam James9-2/+53
GCC 15 introduces allocation dead code removal (DCE) for PR117370 in r15-5255-g7828dc070510f8. This breaks various glibc tests which want to assert various properties of the allocator without doing anything obviously useful with the allocated memory. Alexander Monakov rightly pointed out that we can and should do better than passing -fno-malloc-dce to paper over the problem. Not least because GCC 14 already does such DCE where there's no testing of malloc's return value against NULL, and LLVM has such optimisations too. Handle this by providing malloc (and friends) wrappers with a volatile function pointer to obscure that we're calling malloc (et. al) from the compiler. Reviewed-by: Paul Eggert <eggert@cs.ucla.edu>

2024-12-05Use M_LIT in place of M_MLIT for literalsJoseph Myers2-2/+2
This should fix the reported issue building cospi and sinpi with GCC 6. Tested for x86_64 (not with GCC 6).
2024-12-05Add further test of TLSJoseph Myers11-0/+381
Add an additional test of TLS variables, with different alignment, accessed from different modules. The idea of the alignment test is similar to tst-tlsalign and the same code is shared for setting up test variables, but unlike the tst-tlsalign code, there are multiple threads and variables are accessed from multiple objects to verify that they get a consistent notion of the address of an object within a thread. Threads are repeatedly created and shut down to verify proper initialization in each new thread. The test is also repeated with TLS descriptors when supported. (However, only initial-exec TLS is covered in this test.) Tested for x86_64.
2024-12-05hurd: Protect against servers returning bogus read/write lengthsSergey Bugaev2-8/+14
There already was a branch checking for this case in _hurd_fd_read () when the data is returned out-of-line. Do the same for inline data, as well as for _hurd_fd_write (). It's also not possible for the length to be negative, since it's stored in an unsigned integer. Not verifying the returned length can confuse the callers who assume the returned length is always reasonable. This manifested as libzstd test suite failing on writes to /dev/zero, even though the write () call appeared to succeed. In fact, the zero store backing /dev/zero was returning a larger written length than the size actually submitted to it, which is a separate bug to be fixed on the Hurd side. With this patch, EGRATUITOUS is now propagated to the caller.
