Summary: 6xx reply handling
Initial Comment:
I found two bugs in 6xx reply handing in TM:
1) according to RFC3261, no branch should be added after a 6xx reply (no more
serial forking):
Chapter 6 Definitions:
Sequential Search: In a sequential search, a proxy server attempts each
contact address in sequence, proceeding to the next one only after the previous
has generated a final response. A 2xx or 6xx class final response always
terminates a sequential search.
16.7 Response Processing (Point 5)
If a 6xx response is received, it is not immediately forwarded,but the
stateful proxy SHOULD cancel all client pending transactions as described in
Section 10, and it MUST NOT create any new branches in this context.
2) ignoring bug 1), if after a 6xx reply, a new branch is added in failure
route or callback, the pending branches (from the same set with 6xx reply) are
not cancelled any more.
