| * | | | mac80211: allow driver to generate P1K for IV32Johannes Berg2011-07-081-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support pre-populating the P1K cache in iwlwifi hardware for WoWLAN, we need to calculate the P1K for the current IV32. Allow drivers to get the P1K for any given IV32 instead of for a given packet, but keep the packet-based version around as an inline.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to implement GTK rekeying, the device needs to be able to encrypt frames with the right PN/IV and check the PN/IV in RX frames. To be able to tell it about all those counters, we need to be able to get them from mac80211, this adds the required API. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

| * | | | mac80211: fix TKIP races, make API easier to useJohannes Berg2011-07-081-26/+22

This can lead to bad IVs etc. Also, the crypto offload helper code just obtains the P1K/P2K from the cache, and can update it as well, but there's no guarantee that packets are really processed in order. To fix these issues, first introduce a spinlock that will protect the IV16/IV32 values in the TX context. This first step makes sure that we don't assign the same IV multiple times or get confused in other ways. Secondly, change the way the P1K cache works. I add a field "p1k_iv32" that stores the value of the IV32 when the P1K was last recomputed, and if different from the last time, then a new P1K is recomputed. This can cause the P1K computation to flip back and forth if packets are processed out of order. All this also happens under the new spinlock. Finally, because there are argument differences, split up the ieee80211_get_tkip_key() API into ieee80211_get_tkip_p1k() and ieee80211_get_tkip_p2k() and give them the correct arguments.

This behavior is already practiced in TCP. We do not check the input queue because that would mean to parse all chunks on it to look for unacknowledged data which seems too much of an effort. Control chunks or duplicated chunks may also be in the input queue and should not be stopping a graceful shutdown.

| * | | | | sctp: Enforce retransmission limit during shutdownThomas Graf2011-07-071-0/+1

The graceful shutdown will wait for all outstanding TSN to be acknowledged before sending the SHUTDOWN request. This never happens due to the peer's zero window not acknowledging the continuously retransmitted data chunks. Although the error counter is incremented for each failed retransmission, the receiving of the SACK announcing the zero window clears the error count again immediately. Also heartbeat requests continue to be sent periodically. The peer acknowledges these requests causing the error counter to be reset as well. This patch changes behaviour to only reset the overall error counter for the above rules while not in shutdown. After reaching the maximum number of retransmission attempts, the T5 shutdown guard timer is scheduled to give the receiver some additional time to recover. The timer is stopped as soon as the receiver acknowledges any data. The issue can be easily reproduced by establishing a sctp association over the loopback device, constantly queueing data at the sender while not reading any at the receiver. Wait for the window to reach zero, then initiate a shutdown by killing both processes simultaneously. The association will never be freed and the chunks on the retransmission queue will be retransmitted indefinitely.

In order to successfully go through GTK rekeying, the KEK, KCK and the replay counter are required. Add API to let the supplicant hand the parameters to the driver which may store it for future GTK rekey operations. Note that, of course, if GTK rekeying is done by the device, the EAP frame must not be passed up to userspace, instead a rekey event needs to be sent to let userspace update its replay counter.

Routing table entries, as well as clones made in response to route lookup requests, all live in the same table. And all of these things are together collected in the destination cache table for ipv6. This means that routing table entries count against the garbage collection limits, even though such entries cannot ever be reclaimed and are added explicitly by the administrator (rather than being created in response to lookups). Therefore it makes no sense to count ipv6 routing table entries against the GC limits. Add a DST_NOCOUNT destination cache entry flag, and skip the counting if it is set. Use this flag bit in ipv6 when adding routing table entries. Signed-off-by: David S. Miller <davem@davemloft.net>

Note that links may still be modified or renamed while a dump is taking place but we can guarantee for userspace to receive a complete list of links and not miss any. Testing: I have added 500 VLAN netdevices to make sure the dump is split over multiple messages. Then while continuously dumping links in one process I also continuously deleted and re-added a dummy netdevice in another process. Multiple dumps per seconds have had the NLM_F_DUMP_INTR flag set. I guess we can wait for Johannes patch to hit net-next via the wireless tree. I just wanted to give this some testing right away.

To achieve this, add a sequence counter to the netlink callback struct. Of course, netlink code still needs to use this new functionality. The correct way to do that is to always set cb->seq when a dumpit callback is invoked and call nl_dump_check_consistent() for each new message. The core code will also call this function for the final MSG_DONE message. To make it usable with generic netlink, a new function genlmsg_nlhdr() is needed to obtain the netlink header from the genetlink user header.
