linux(4): Handle SO_TIMESTAMPNS socket option 2022-05-28T20:46:05+00:00 Dmitry Chagin dchagin@FreeBSD.org 2022-05-28T20:46:05+00:00 71bc8bcf660b437b99af1e3d382f7bfdaea5fa9c The SO_TIMESTAMPNS enables or disables the receiving of the SCM_TIMESTAMPNS control message. The cmsg_data field is a struct timespec. To distinguish between SO_TIMESTAMP and SO_TIMESTAMPNS in the recvmsg() map the last one to the SO_BINTIME and convert bintime to the timespec. In the rest, implementation is identical to the SO_TIMESTAMP. MFC after: 2 weeks

linux(4): Handle 64-bit SO_TIMESTAMP for 32-bit binaries 2022-05-28T20:45:39+00:00 Dmitry Chagin dchagin@FreeBSD.org 2022-05-28T20:45:39+00:00 0e26e54bdfa2859908150011a4a165e9dd3de9ac To solve y2k38 problem in the recvmsg syscall the new SO_TIMESTAMP constant were added on v5.1 Linux kernel. So, old 32-bit binaries that knows only 32-bit time_t uses the old value of the constant, and binaries that knows 64-bit time_t uses the new constant. To determine what size of time_t type is expected by the user-space, store requested value (SO_TIMESTAMP) in the process emuldata structure. MFC after: 2 weeks
