Description Marcel Holtmann 2006-08-29 10:40:58 UTC 
From Sridhar Samudrala:

With the recent fix, the callers of sctp_primitive_ABORT() need to create an
ABORT chunk and pass it as an argument rather than msghdr that was passed earlier.

This is a regression with bug 202122 (CVE-2006-3745).
Comment 2 Marcel Holtmann 2006-09-01 06:10:05 UTC 
The regression causes a panic if an SCTP socket has SO_LINGER set with a linger
value of 0 and it is closed.
Comment 3 Neil Horman 2006-09-14 12:23:10 UTC 
Looks pretty obvious.  Let me smoke test it quick and I'll post it.
