[lwip-devel] [bug #28054] Two segments with FIN flag on the out-of-sequence queue

[Kieran Mansley]

Follow-up Comment #2, bug #28054 (project lwip):

>From looking at the code it looks like we do the right thing when the second
segment is in order - there is lots of checking of TCP flags there - but
ignore them completely when trimming if the second segment is also out of
order.  Whenever we trim a segment in that section (tcp_in.c:1244 -> 1363) we
need to check the flags and removing any FIN if present.
