src/sys/kern: uipc_socket2.c
src/sys/miscfs/fifofs: fifo_vnops.c
src/tests/lib/libc/sys: t_poll.c
Log Message:
- fifo_poll(): If the last writer has disappeared, detect this and return
POLLHUP, per POSIX.
- fifo_close(): Use the new fifo_socantrcvmore(), which is like the
garden-variety socantrcvmore(), except it specifies POLL_HUP rather
than POLL_IN (so the correct code for SIGIO is sent).
- sowakeup(): Allow POLL_HUP as a code (notifies poll'ers with POLLHUP).
- Add test cases for correct POLLHUP behavior with FIFOs.
Fixes PR kern/56429.
