| * sctp: make sctp over IPv6 work with IPsecVlad Yasevich2011-04-271-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | SCTP never called xfrm_output after it's v6 route lookups so that never really worked with ipsec. Additioanlly, we never passed port nubmers and protocol in the flowi, so any port based policies were never applied as well. Now that we can fixed ipv6 routing lookup code, using ip6_dst_lookup_flow() and pass port numbers.

| * sctp: cache the ipv6 source after route lookupVlad Yasevich2011-04-274-119/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipv6 routing lookup does give us a source address, but instead of filling it into the dst, it's stored in the flowi. We can use that instead of going through the entire source address selection again. Also the useless ->dst_saddr member of sctp_pf is removed. And sctp_v6_dst_saddr() is removed, instead by introduce sctp_v6_to_addr(), which can be reused to cleanup some dup code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When processing an ACK for ADD_IP parameter, we only release the routes on non-active transports. This can cause a wrong source address to be used. We can release the routes and cause new route lookups and source address selection so that new addresses can be used as source. Additionally, we don't need to lookup routes for all transports at the same time. We can let the transmit code path update the cached route when the transport actually sends something.

| * sctp: teach CACC algorithm about removed transportsVlad Yasevich2011-04-191-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have have to remove a transport due to ASCONF, we move the data to a new active path. This can trigger CACC algorithm to not mark that data as missing when SACKs arrive. This is because the transport passed to the CACC algorithm is the one this data is sitting on, not the one it was sent on (that one may be gone). So, by sending the original transport (even if it's NULL), we may start marking data as missing.

* sctp: fix reporting of unknown parametersJiri Bohac2011-02-191-5/+5
| | | | | | | | | | | | | commit 5fa782c2f5ef6c2e4f04d3e228412c9b4a4c8809 re-worked the handling of unknown parameters. sctp_init_cause_fixed() can now return -ENOSPC if there is not enough tailroom in the error chunk skb. When this happens, the error header is not appended to the error chunk. In that case, the payload of the unknown parameter should not be appended either.
