Subject: [glibc] linux: Consolidate Linux getsockopt implementation
Date: Tue, 6 Jul 2021 14:45:40 +0000 (GMT) [thread overview]
Message-ID: <20210706144540.DF8FE383D029@sourceware.org> (raw)
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=1c46663a70d7225102b9c7adda542d3782353db6
commit 1c46663a70d7225102b9c7adda542d3782353db6
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Jul 5 13:44:26 2021 -0300
linux: Consolidate Linux getsockopt implementation
This patch consolidates the getsockopt Linux syscall implementation on
sysdeps/unix/sysv/linux/getsockopt.c. The changes are:
1. Remove it from auto-generation syscalls.list on all architectures.
2. Add __ASSUME_GETSOCKOPT_SYSCALL as default and undef if for
specific kernel versions on some architectures.
This also fix a potential issue where 32-bit time_t ABI should use the
linux getsockopt which overrides the underlying SO_* constants used for
socket timestamping for _TIME_BITS=64.
Checked on x86_64-linux-gnu and i686-linux-gnu.
