* linux: Update the mremap C implementation [BZ #31968]H.J. Lu2024-08-011-1/+13
| | | | | | | | | | | | | | Update the mremap C implementation to support the optional argument for MREMAP_DONTUNMAP added in Linux 5.7 since it may not always be correct to implement a variadic function as a non-variadic function on all Linux targets. Return MAP_FAILED and set errno to EINVAL for unknown flag bits. This fixes BZ #31968. Note: A test must be added when a new flag bit is introduced. Signed-off-by: H.J.

* AArch64: Check kernel version for SVE ifuncsWilco Dijkstra2024-04-082-0/+49
| | | | | | | | | | | | | | | | | Old Linux kernels disable SVE after every system call. Calling the SVE-optimized memcpy afterwards will then cause a trap to reenable SVE. As a result, applications with a high use of syscalls may run slower with the SVE memcpy. This is true for kernels between 4.15.0 and before 6.2.0, except for 5.14.0 which was patched. Avoid this by checking the kernel version and selecting the SVE ifunc on modern kernels. Parse the kernel version reported by uname() into a 24-bit kernel.major.minor value without calling any library functions. If uname() is not supported or if the version format is not recognized, assume the kernel is modern.

* linux: Use rseq area unconditionally in sched_getcpu (bug 31479)Florian Weimer2024-03-181-8/+0
| | | | | | | | | | | | | | | | | | | | | Originally, nptl/descr.h included <sys/rseq.h>, but we removed that in commit 2c6b4b272e6b4d07303af25709051c3e96288f2d ("nptl: Unconditionally use a 32-byte rseq area"). After that, it was not ensured that the RSEQ_SIG macro was defined during sched_getcpu.c compilation that provided a definition. This commit always checks the rseq area for CPU number information before using the other approaches. This adds an unnecessary (but well-predictable) branch on architectures which do not define RSEQ_SIG, but its cost is small compared to the system call. Most architectures that have vDSO acceleration for getcpu also have rseq support.

| | | | | | | | | | | | | | | | | | | | Different than other 64 bit architectures, powerpc64 defines the LFS POSIX lock constants with values similar to 32 ABI, which are meant to be used with fcntl64 syscall. Since powerpc64 kABI does not have fcntl, the constants are adjusted with the FCNTL_ADJUST_CMD macro. The 4d0fe291aed3a476a changed the logic of generic constants LFS value are equal to the default values; which is now wrong for powerpc64. Fix the value by explicit define the previous glibc constants (powerpc64 does not need to use the 32 kABI value, but it simplifies the FCNTL_ADJUST_CMD which should be kept as compatibility).

| | | | | | | | | | | | | | | | | | | (BZ#30477) For architecture with default 64 bit time_t support, the kernel does not provide LFS and non-LFS values for F_GETLK, F_GETLK, and F_GETLK (the default value used for 64 bit architecture are used). This is might be considered an ABI break, but the currenct exported values is bogus anyway. The POSIX lockf is not affected since it is aliased to lockf64, which already uses the LFS values.

* __check_pf: Add a cancellation cleanup handler [BZ #20975]H.J. Lu2023-05-232-0/+17
| | | | | | | | | | | | | | | | | | | | | | There are reports for hang in __check_pf: https://github.com/JoeDog/siege/issues/4 It is reproducible only under specific configurations: 1. Large number of cores (>= 64) and large number of threads (> 3X of the number of cores) with long lived socket connection. 2. Low power (frequency) mode. 3. Power management is enabled. While holding lock, __check_pf calls make_request which calls __sendto and __recvmsg. Since __sendto and __recvmsg are cancellation points, lock held by __check_pf won't be released and can cause deadlock when thread cancellation happens in __sendto or __recvmsg. Add a cancellation cleanup handler for __check_pf to unlock the lock when cancelled by another thread. This fixes BZ #20975 and the siege hang issue.

* Linux: Support __IPC_64 in sysvctl *ctl command arguments (bug 29771)Florian Weimer2022-11-114-26/+63
| | | | | | | | | | | | | | | | | | Old applications pass __IPC_64 as part of the command argument because old glibc did not check for unknown commands, and passed through the arguments directly to the kernel, without adding __IPC_64. Applications need to continue doing that for old glibc compatibility, so this commit enables this approach in current glibc. For msgctl and shmctl, if no translation is required, make direct system calls, as we did before the time64 changes. If translation is required, mask __IPC_64 from the command argument. For semctl, the union-in-vararg argument handling means that translation is needed on all architectures.
