Subject: [PATCH net 0/2] Fix two further potential unbounded recursions in GUE error handlers

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.

Stefano Brivio (2):
  fou: Prevent unbounded recursion in GUE error handler also with
    UDP-Lite
  fou6: Prevent unbounded recursion in GUE error handler
