Question regarding handling of ootb packets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
