* selftests: timers: set-timer-lat: fix hang when std out/err are redirectedShuah Khan2017-09-251-3/+1
| | | | | | | | | | | | | | | do_timer_oneshot() uses select() as a timer with FD_SETSIZE and readfs is cleared with FD_ZERO without FD_SET. When stdout and stderr are redirected, the test hangs in select forever. Fix the problem calling select() with readfds empty and nfds zero. This is sufficient for using select() for timer. With this fix "./set-timer-lat > /dev/null 2>&1" no longer hangs.

* selftests/seccomp: Support glibc 2.26 siginfo_t.hKees Cook2017-09-251-5/+13
| | | | | | | | | | | | | | | | The 2.26 release of glibc changed how siginfo_t is defined, and the earlier work-around to using the kernel definition are no longer needed. The old way needs to stay around for a while, though.

| * | sctp: do not mark sk dumped when inet_sctp_diag_fill returns errXin Long2017-09-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill returns err, in which case it shouldn't mark sk dumped by setting cb->args[3] as 1 in sctp_sock_dump(). Otherwise, it could cause some asocs to have no parent's sk dumped in 'ss --sctp'. So this patch is to not set cb->args[3] when inet_sctp_diag_fill() returns err in sctp_sock_dump().

| * | sctp: fix an use-after-free issue in sctp_sock_dumpXin Long2017-09-153-39/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 86fdb3448cc1 ("sctp: ensure ep is not destroyed before doing the dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep with holding sock and sock lock. But Paolo noticed that endpoint could be destroyed in sctp_rcv without sock lock protection. It means the use-after-free issue still could be triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks !ep, although it's pretty hard to reproduce. I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close and sctp_sock_dump long time. This patch is to add another param cb_done to sctp_for_each_transport and dump ep->assocs with holding tsp after jumping out of transport's traversal in it to avoid this issue. It can also improve sctp diag dump to make it run faster, as no need to save sk into cb->args[5] and keep calling sctp_for_each_transport any more. This patch is also to use int * instead of int for the pos argument in sctp_for_each_transport, which could make postion increment only in sctp_for_each_transport and no need to keep changing cb->args[2] in sctp_sock_filter and sctp_sock_dump any more.
