* PR #1433: Fix incorrect timespec definition on 32-bit platforms with 64-bit ↵Gravatar Oleg Lyovin2023-05-02
| | | | | | | | | | | | | | | | | time_t Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1433 Some 32-bit configurations may use 64-bit time_t, which leads to different layout of userspace timespec and the one expected by SYS_futex implementation in kernel. In particular the issue occurs when using musl libc which has switched to unconditional 64-bit time_t definition. This patch introduces custom struct timespec with two longs when old SYS_futex is used to match the kernel timespec definition.

* | Fix handling of `CHECK` macros in static analysis tools.Gravatar Abseil Team2023-04-24
| | | | | | | | | | | | | | Currently static analysis tools built using the Clang Dataflow Analysis framework can't prove that code under `switch (0) case 0:` is executed on all paths. The Clang Dataflow Analysis framework should ultimately be improved to handle these cases. In the meantime, to enable the use of such tools in their current state, we add a `default` case back to the `switch` statement in `ABSL_LOG_INTERNAL_STATELESS_CONDITION` to help them understand that the code is executed on all paths.

* Name anonymous memory allocations on Linux.Gravatar Abseil Team2023-04-12
| | | | | | | | | | | | | | | | | | | Use Linux's prctl(PR_SET_VMA) system call to name memory arenas being allocated using mmap(MAP_ANONYMOUS). This change allows Abseil's memory arena(s) to be distinguished from other uses of anonymous memory within a process, which in turn helps investigations into the memory usage of applications. The change adds a new prctl() system call to the code paths that call mmap(). This is not expected to add significant overhead to applications. The call to prctl(PR_SET_VMA, ...) can fail if the Linux kernel in use was not configured with the CONFIG_ANON_VMA_NAME kernel option. This should be OK since the naming memory regions is primarily a debugging aid. PiperOrigin-RevId: 523687348 Change-Id: Ie404e5eeef0a6da53330b3a56149c4f3bc6bf5c7
