2011-09-16sctp: deal with multiple COOKIE_ECHO chunksMax Matveev
Attempt to reduce the number of IP packets emitted in response to single SCTP packet (2e3216cd) introduced a complication - if a packet contains two COOKIE_ECHO chunks and nothing else then SCTP state machine corks the socket while processing first COOKIE_ECHO and then loses the association and forgets to uncork the socket. To deal with the issue add new SCTP command which can be used to set association explictly. Use this new command when processing second COOKIE_ECHO chunk to restore the context for SCTP state machine. Signed-off-by: Max Matveev <makc@redhat.com> Signed-off-by: David S.

2011-08-06net: Compute protocol sequence numbers and fragment IDs using MD5.David S. Miller
Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

2011-08-03net: fix NULL dereferences in check_peer_redir()Eric Dumazet
Gergely Kalman reported crashes in check_peer_redir(). It appears commit f39925dbde778 (ipv4: Cache learned redirect information in inetpeer.) added a race, leading to possible NULL ptr dereference. Since we can now change dst neighbour, we should make sure a reader can safely use a neighbour. Add RCU protection to dst neighbour, and make sure check_peer_redir() can be called safely by different cpus in parallel. As neighbours are already freed after one RCU grace period, this patch should not add typical RCU penalty (cache cold effects) Many thanks to Gergely for providing a pretty report pointing to the bug.

2011-07-13mac80211: allow driver to disconnect after resumeJohannes Berg
In WoWLAN, devices may use crypto keys for TX/RX and could also implement GTK rekeying. If the driver isn't able to retrieve replay counters and similar information from the device upon resume, or if the device isn't responsive due to platform issues, it isn't safe to keep the connection up as GTK rekey messages from during the sleep time could be replayed against it. The only protection against that is disconnecting from the AP. Modifying mac80211 to do that while it is resuming would be very complex and invasive in the case that the driver requires a reconfig, so do it after it has resumed completely. In that case, however, packets might be replayed since it can then only happen after TX/RX are up again, so mark keys for interfaces that need to disconnect as "tainted" and drop all packets that are sent or received with those keys.
