The recvmsg handling is more complicated because it requires check the returned kernel control message and make some convertions. For !__ASSUME_TIME64_SYSCALLS it converts the first 32-bit time SO_TIMESTAMP or SO_TIMESTAMPNS and appends it to the control buffer if has extra space or returns MSG_CTRUNC otherwise. The 32-bit time field is kept as-is. Calls with __TIMESIZE=32 will see the converted 64-bit time control messages as spurious control message of unknown type. Calls with __TIMESIZE=64 running on pre-time64 kernels will see the original message as a spurious control ones of unknown typ while running on kernel with native 64-bit time support will only see the time64 version of the control message. Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15 kernel). Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com> |
