* Linux: Move mq_send, mq_timedsend, __mq_timedsend_time64 to libcFlorian Weimer2021-06-251-6/+6

* Linux: Move mq_notify from librt to libcFlorian Weimer2021-06-251-0/+4
| | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. An explicit call from fork into the mq_notify implementation replaces the previous use of pthread_atfork. Reviewed-by: Adhemerva Zanella <adhemerval.zanella@linaro.org>
* Linux: Move mq_setattr from librt to libcFlorian Weimer2021-06-251-0/+7
| | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. To introduce the proper symbol versioning, the implementation of the system call wrapper us moved to a C file. Reviewed-by: Adhemerva Zanella <adhemerval.zanella@linaro.org>
* y2038: linux: Provide __mq_timedreceive_time64 implementationLukasz Majewski2020-04-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides new __mq_timedreceive_time64 explicit 64 bit function for receiving messages with absolute timeout. Moreover, a 32 bit version - __mq_timedreceive has been refactored to internally use __mq_timedreceive_time64. The __mq_timedreceive is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversion to 64 bit struct __timespec64 from struct timespec. The new mq_timedsend_time64 syscall available from Linux 5.1+ has been used, when applicable. As this wrapper function is also used internally in the glibc, to e.g. provide mq_receive implementation, an explicit check for abs_timeout being NULL has been added due to conversions between struct timespec and struct __timespec64. Before this change the Linux kernel handled this NULL pointer. 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 Linux kernel, headers and minimal kernel version for glibc build test matrix: - Linux v5.1 (with mq_timedreceive_time64) and glibc built with v5.1 as minimal kernel version (--enable-kernel="5.1.0") The __ASSUME_TIME64_SYSCALLS flag defined. - Linux v5.1 and default minimal kernel version The __ASSUME_TIME64_SYSCALLS not defined, but kernel supports mq_timedreceive_time64 syscall. - Linux v4.19 (no mq_timedreceive_time64 support) with default minimal kernel version for contemporary glibc (3.2.0) This kernel doesn't support mq_timedreceive_time64 syscall, so the fallback to mq_timedreceive is tested. Above tests were performed with Y2038 redirection applied as well as without (so the __TIMESIZE != 64 execution path is checked as well).

* Fix mq_receive, mq_send mq_timed* namespace (bug 18545).Joseph Myers2015-06-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | mq_receive calls mq_timedreceive, and mq_send calls mq_timedsend. But mq_receive and mq_send were in POSIX by 1996, while mq_timed* were added in the 2001 edition of POSIX. This patch fixes this by making mq_timed* into weak aliases for __mq_timed* and calling the __mq_timed* names. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #18545] * rt/mq_timedreceive.c (mq_timedreceive): Rename to __mq_timedreceive and define as alias of __mq_timedreceive. Use hidden_weak. * rt/mq_timedsend.c (mq_timedsend): Rename to __mq_timedsend and define as alias of __mq_timedsend. Use hidden_weak. * sysdeps/unix/sysv/linux/syscalls.list (mq_timedsend): Use __mq_timedsend as strong name. (mq_timedreceive): Use __mq_timedreceive as strong name. * include/mqueue.h (__mq_timedsend): Declare. Use hidden_proto. (__mq_timedreceive): Likewise. * sysdeps/unix/sysv/linux/mq_receive.c (mq_receive): Call __mq_timedreceive instead of mq_timedreceive. * sysdeps/unix/sysv/linux/mq_send.c (mq_send): Call __mq_timedsend instead of mq_timedsend. * conform/Makefile (test-xfail-UNIX98/mqueue.h/linknamespace): Remove variable.
* Use IS_IN internally onlySiddhesh Poyarekar2014-11-241-1/+3
| | | | | | | | | | | | This change is only useful for the conformance tests since the headers changed are not installed. The conformance tests fail due to IS_IN not being defined, so wrap it with a check to make sure that _ISOMAC is defined. * include/bits/stdlib-float.h: Use IS_IN only if _ISOMAC is defined. * include/mqueue.h: Likewise. * include/stdlib.h: Likewise.
