Subject: [PATCH net 0/2] mptcp: mptcp: fix deadlock in mptcp{,6}_release
Date: Thu, 1 Apr 2021 18:57:43 +0200 [thread overview]
Message-ID: <cover.1617295578.git.pabeni@redhat.com> (raw)
syzkaller has reported a few deadlock triggered by
mptcp{,6}_release.
These patches address the issue in the easy way - blocking
the relevant, multicast related, sockopt options on MPTCP
sockets.
Note that later on net-next we are going to revert patch 1/2,
as a part of a larger MPTCP sockopt implementation refactor
Paolo Abeni (2):
mptcp: forbit mcast-related sockopt on MPTCP sockets
mptcp: revert "mptcp: provide subflow aware release function"
