Subject: Question regarding handling of ootb packets
Date: Tue, 19 Jan 2010 02:42:54 +0000 [thread overview]
Message-ID: <20100119024254.GA2161@localhost.localdomain> (raw)
Hey all-
I'm having a bit of trouble understanding the implementation of
sctp_rcv_ootb. Specifically I'm wondering why we allow packets checked in
sctp_rcv_ootb with malformed chunks into the receive queue. For instance, if a
chunk in an ootb packet has a zero length, we break out of the loop and return
0, which lets us eventually call sctp_inq_push to put it on the receive queue,
from which point on we seem to assume the chunk header length field is valid and
correct. Am I missing something, or is this a bug?
Thanks!
Neil
