Thanks for looking into it. I can try with your patch, but no
guarantees that the fuzzer will hit the same condition in some
reasonable time-frame. Will get back in some time with results.
Ok, thanks!
PS. If you think it's possible to create a repro (userland code) which
can trigger this, I can give it a try.
Did by accident trinity create tunnels? It looks that upper layer
protocols (except SCTP) all allocate and reserve MAX_HEADER to
accommodate enough head room in worst case for possible tunnels.
Not sure, but I run it inside a pid/ipc/uts/etc/user-namespaces where
it operates with a full set of capabilities, so most of the SOCK_RAW
and tunnel-like-creating calls succeed, so maybe..
Ok thanks, can you post your .config?
