2009-11-11mac80211: fix max HT rate processing on mac80211Luis R. Rodriguez
The max MCS index is 76, fix the higher check to allow through frames received at MCS 76. This is a non-issue for current drivers as MCS 76 is only possible with a device supporting 4 spatial streams. While at it change the WARN_ON() on invalid HT rates to a WARN() to provide more useful information. This will help debug issues when the driver is passing up a bogus HT rate value. The rate must map to a valid MCS index which can be any of the values in the set [0 - 76] (inclusive). Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

2009-11-11mac80211: implement support for 4-address frames for AP and client modeFelix Fietkau
In some situations it might be useful to run a network with an Access Point and multiple clients, but with each client bridged to a network behind it. For this to work, both the client and the AP need to transmit 4-address frames, containing both source and destination MAC addresses. With this patch, you can configure a client to communicate using only 4-address frames for data traffic. On the AP side you can enable 4-address frames for individual clients by isolating them in separate AP VLANs which are configured in 4-address mode. Such an AP VLAN will be limited to one client only, and this client will be used as the destination for all traffic on its interface, regardless of the destination MAC address in the packet headers. The advantage of this mode compared to regular WDS mode is that it's easier to configure and does not require a static list of peer MAC addresses on any side.

2009-11-08xfrm: SAD entries do not expire correctly after suspend-resumeYury Polyanskiy
This fixes the following bug in the current implementation of net/xfrm: SAD entries timeouts do not count the time spent by the machine in the suspended state. This leads to the connectivity problems because after resuming local machine thinks that the SAD entry is still valid, while it has already been expired on the remote server. The cause of this is very simple: the timeouts in the net/xfrm are bound to the old mod_timer() timers. This patch reassigns them to the CLOCK_REALTIME hrtimer. I have been using this version of the patch for a few months on my machines without any problems. Also run a few stress tests w/o any issues. This version of the patch uses tasklet_hrtimer by Peter Zijlstra (commit 9ba5f0). This patch is against 2.6.31.4. Please CC me.

If too many sockets are listed, we take a look at the secondary (port, address) hash chain. We choose the shortest chain and proceed with a RCU lookup on the elected chain. But, if we chose (port, address) chain, and fail to find a socket on given address, we must try another lookup on (port, in6addr_any) chain to find sockets not bound to a particular IP. -> No extra cost for typical setups, where the first lookup will probabbly be performed.

There is no good reason to not support userspace specifying the network namespace during device creation, and it makes it easier to create a network device and pass it to a child network namespace with a well known name. We have to be careful to ensure that the target network namespace for the new device exists through the life of the call. To keep that logic clear I have factored out the network namespace grabbing logic into rtnl_link_get_net. In addtion we need to continue to pass the source network namespace to the rtnl_link_ops.newlink method so that we can find the base device source network namespace. Signed-off-by: Eric W.
