Paolo Abeni fd8976790a mptcp: be careful on MPTCP-level ack. ... We can enter the main mptcp_recvmsg() loop even when no subflows are connected. As note by Eric, that would result in a divide by zero oops on ack generation. Address the issue by checking the subflow status before sending the ack. Additionally protect mptcp_recvmsg() against invocation with weird socket states. v1 -> v2: - removed unneeded inline keyword - Jakub Reported-and-suggested-by: Eric Dumazet <eric.dumazet@gmail.com> Fixes: ea4ca586b1 ("mptcp: refine MPTCP-level ack scheduling") Signed-off-by: Paolo Abeni <pabeni@redhat.com> Link: https://lore.kernel.org/r/5370c0ae03449239e3d1674ddcfb090cf6f20abe.1606253206.git.pabeni@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2020-11-25 13:36:16 -08:00
