__futex_abstimed_wait_cancelable64 By mistake the if for calling __futex_abstimed_wait_cancellable32 was misaligned with the rest of the function body.
2020-09-07Disable -Wstringop-overread for some string testsJoseph Myers2-0/+11
Similarly to Maciej's changes to fix the build of rawmemchr in the presence of GCC 11's -Wstringop-overread, also disable that option in two string function tests that have similar warnings and other string function warnings already disabled. Tested with build-many-glibcs.py for aarch64-linux-gnu and arm-linux-gnueabi that it fixes building the glibc testsuite.

2020-09-07C11 threads: Fix inaccuracies in testsuiteCorinna Vinschen3-3/+3
- tst-mtx-recursive.c: mtx_init fails to use mtx_plain. Per C11 specs, using mtx_recursive alone is not supported. This isn't catched because mtx_plain is defined as 0. - tst-thrd-sleep.c: thrd_sleep returns 0 on success, a negative value on failure. Testing against thrd_success is incorrect. - tst-tss-basic.c: tss_set is incorrectly checkd for a non-0 value. The test should test aginst C11 threads error codes. This isn't catched because thrd_success is defined as 0. Note that all three tests fail on FreeBSD, which defines all mutex type values, as well as all C11 threads error codes with non-0 values.

This is the first of a series of patches to sync with Gnulib commit 615b43e1f9. This patch adopts most of the changes of Gnulib, except it retains GETCWD_RETURN_TYPE and does not always use a 64-bit internal API. These remaining discrepancies will be addressed in later patches in this series. Checked on x86_64-linux-gnu and i686-linux-gnu.
2020-09-02x86-64: Fix FMA4 detection in ifunc [BZ #26534]Ondřej Hošek1-1/+1
A typo in commit 107e6a3c2212ba7a3a4ec7cae8d82d73f7c95d0b causes the FMA4 code path to be taken on systems that support FMA, even if they do not support FMA4. Fix this to detect FMA4.
2020-09-02y2038: nptl: Convert pthread_cond_{clock|timed}wait to support 64 bit timeLukasz Majewski5-9/+152
The pthread_cond_clockwait and pthread_cond_timedwait have been converted to support 64 bit time. This change introduces new futex_abstimed_wait_cancelable64 function in ./sysdeps/nptl/futex-helpers.c, which uses futex_time64 where possible and tries to replace low-level preprocessor macros from lowlevellock-futex.h The pthread_cond_{clock|timed}wait only accepts absolute time. Moreover, there is no need to check for NULL passed as *abstime pointer as __pthread_cond_wait_common() always passes non-NULL struct __timespec64 pointer to futex_abstimed_wait_cancellable64(). For systems with __TIMESIZE != 64 && __WORDSIZE == 32: - Conversions between 64 bit time to 32 bit are necessary - Redirection to __pthread_cond_{clock|timed}wait64 will provide support for 64 bit time The futex_abstimed_wait_cancelable64 function has been put into a separate file on the purpose - to avoid issues apparent on the m68k architecture related to small number of available registers (there is not enough registers to put all necessary arguments in them if the above function would be added to futex-internal.h with __always_inline attribute). In fact - new function - namely __futex_abstimed_wait_cancellable32 is used to reduce number of needed registers (as some in-register values are stored on the stack when function call is made). Build tests: ./src/scripts/build-many-glibcs.py glibcs Run-time tests: - Run specific tests on ARM/x86 32bit systems (qemu): https://github.com/lmajewski/meta-y2038 and run tests: https://github.com/lmajewski/y2038-tests/commits/master Above tests were performed with Y2038 redirection applied as well as without to test the proper usage of both __pthread_cond_{clock|timed}wait64 and __pthread_cond_{clock|timed}wait.

2020-08-27RISC-V: Use 64-bit time_t and off_t for RV32 and RV64Alistair Francis4-0/+162
Using the original glibc headers under bits/ let's make small modifications to use 64-bit time_t and off_t for both RV32 and RV64. For the typesizes.h, here are justifications for the changes from the generic version (based on Arnd's very helpful feedback): - All the !__USE_FILE_OFFSET64 types (__off_t, __ino_t, __rlim_t, ...) are changed to match the 64-bit replacements. - __time_t is defined to 64 bit, but no __time64_t is added. This makes sense as we don't have the time64 support for other 32-bit architectures yet, and it will be easy to change when that happens. - __suseconds_t is 64-bit. This matches what we use the kernel ABI for the few drivers that are relying on 'struct timeval' input arguments in ioctl, as well as the adjtimex system call. It means that timeval has to be defined without the padding, unlike timespec, which needs padding. Reviewed-by: Maciej W. Rozycki <macro@wdc.com>

It's possible that although __OFF_T_MATCHES_OFF64_T is defined the included the relevent header file. This results in a io/tst-lockf failure for RV32 by calling the non 64-bit version of lockf.
