Subject: [PATCH net 0/2] Fix two further potential unbounded recursions in GUE error handlers
Date: Thu, 3 Jan 2019 21:43:33 +0100 [thread overview]
Message-ID: <cover.1546547862.git.sbrivio@redhat.com> (raw)
Patch 1/2 takes care of preventing the issue fixed by commit 11789039da53
("fou: Prevent unbounded recursion in GUE error handler") also with
UDP-Lite payloads -- I just realised this might happen from a syzbot
report.
Patch 2/2 fixes the issue for both UDP and UDP-Lite on IPv6, which I also
forgot to deal with in that same commit.
