Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532] The kernel changes for a 64-bit time_t on 32-bit architectures resulted in <asm/socket.h> indirectly including <linux/posix_types.h>. The latter is not namespace-clean for the POSIX version of <sys/socket.h>. This issue has persisted across several Linux releases, so this commit creates our own copy of the SO_* definitions for !__USE_MISC mode. The new test socket/tst-socket-consts ensures that the copy is consistent with the kernel definitions (which vary across architectures). The test is tricky to get right because CPPFLAGS includes include/libc-symbols.h, which in turn defines _GNU_SOURCE unconditionally. Tested with build-many-glibcs.py. I verified that a discrepancy in the definitions actually results in a failure of the socket/tst-socket-consts test. 2019-07-24 08:59:34 +00:00			`/* Socket constants which vary among Linux architectures.

Update copyright dates with scripts/update-copyrights I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: * pre-commit check failed ... remote: * error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master 2021-01-02 19:32:25 +00:00			`Copyright (C) 2019-2021 Free Software Foundation, Inc.`

y2038: Add __USE_TIME_BITS64 support for socket-constants.h It is only used for !__USE_MISC, the default way uses the kernel headers. The patch also adds the SO_TIMESTAMP, SO_TIMESTAMPNS, and SO_TIMESTAMPING which uses new values for 64-bit time_t kernel interfaces. The __USE_TIME_BITS64 is not defined internally yet, although the internal header is used when building the 64-bit stat implementations.
