| * | BACKPORT: tcp: enforce tcp_min_snd_mss in tcp_mtu_probing() | Eric Dumazet | 2019-07-18 | 1 | -0/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 967c05aee439e6e5d7d805e195b3a20ef5c433d6 upstream. If mtu probing is enabled tcp_mtu_probing() could very well end up with a too small MSS. Use the new sysctl tcp_min_snd_mss to make sure MSS search is performed in an acceptable range.

| * | tcp: fix various issues for sockets morphing to listen state | Eric Dumazet | 2017-07-04 | 1 | -2/+4 |
| | | | | | | | | | | | | | | | | | | | | | | | | | commit 02b2faaf0af1d85585f6d6980e286d53612acfc2 upstream. Dmitry Vyukov reported a divide by 0 triggered by syzkaller, exploiting tcp_disconnect() path that was never really considered and/or used before syzkaller ;) I was not able to reproduce the bug, but it seems issues here are the three possible actions that assumed they would never trigger on a listener. 1) tcp_write_timer_handler 2) tcp_delack_timer_handler 3) MTU reduction Only IPv6 MTU reduction was properly testing TCP_CLOSE and TCP_LISTEN states from tcp_v6_mtu_reduced() Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: Dmitry Vyukov <dvyukov@google.com> Signed-off-by: David S.
