commit 2efbd3ae03af46d2888321322320513dd08cb5c9
Author: Florian Weimer <fweimer@redhat.com>

recvmsg, sendmsg, recvmmsg, sendmmsg: 2.24 ABI revert compatibility
GLIBC_2.24 compatibility versions are added to be able to run old
binaries, so that use of the GLIBC_2.24 symbol versions can be phased
out gradually.
It uses an endian-agnostic, word-size approach to sanitize the upper
bits of the affected struct members, using the old struct definitions
without padding.
