In this implementation, a mesh gate is a root node with a certain bit set in its RANN flags. The mpath to this root node is marked as a path to a gate, and added to our list of known gates for this if_mesh. Once a path discovery process fails, we forward the unresolved frames to a known gate. Thanks to Luis Rodriguez for refactoring and bug fix help.

This adds proper RCU annotations to the mesh path table code, and fixes a number of bugs in the code that I found while checking the sparse warnings I got as a result of the annotations. Some things like the changes in mesh_path_add() or mesh_pathtbl_init() only serve to shut up sparse, but other changes like the changes surrounding the for_each_mesh_entry() macro fix real RCU bugs in the code.

The locking in mesh_{mpath,mpp}_table_grow not only has an rcu_read_unlock() missing, it's also racy (though really only technically since it's invoked from a single function only) since it obtains the new size of the table without any locking, so two invocations of the function could attempt the same resize. Additionally, it uses synchronize_rcu() which is rather expensive and can be avoided trivially here. Modify the functions to only use the table lock and use call_rcu() instead of synchronize_rcu().

This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live). As that is otherwise harmless, I decided to make it part of this patch. Signed-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

The Mesh Control header only includes 0, 1 or 2 addresses. If there is one address, it should be interpreted as Address 4. If there are 2, they are interpreted as Addresses 5 and 6 (Address 4 being the 4th address in the 802.11 header). The address extension used to hold up to 3 addresses instead of the current 2. I'm not sure which draft version changed this, but it is very unlikely that it will change again given the state of the approval process of this draft. See section 7.1.3.6.3 in current draft (8.0). Also, note that the extra address that I'm removing was not being used, so this change has no effect on over-the-air frame formats. But I thought I better remove it before someone does start using it. Signed-off-by: NJavier Cardona <javier@cozybit.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

Instead of tying mesh activity to interface up, add join and leave commands for mesh. Since we must be backward compatible, let cfg80211 handle joining a mesh if a mesh ID was pre-configured when the device goes up. Note that this therefore must modify mac80211 as well since mac80211 needs to lose the logic to start the mesh on interface up. We now allow querying mesh parameters before the mesh is connected, which simply returns defaults. Setting them (internally renamed to "update") is only allowed while connected. Specify them with the new mesh join command instead where needed. In mac80211, beaconing must now also follow the mesh enabled/not enabled state, which is done by testing the mesh ID.

The netdev broadcast address cannot change from all-ones so there's no need to use it; we can instead hard-code it. Since we already have an instance in tkip.c, which will be shared if it is marked static const, doing this reduces text size at no data/bss cost. The real motivation for this is, of course, the desire to get rid of almost all uses of netdevs in mac80211 so that auditing their use becomes easier.

Mesh uses the tx failure average to compute the (m)path metric. This used to be done inside the rate control module. This patch breaks the dependency between the mesh stack and the rate control algorithm. Mesh will now work independently of the chosen rate control algorithm. The mesh stack keeps a moving average of the average transmission losses for each mesh peer station. If the fail average exceeds a certain threshold, the peer link is marked as broken.

The 11s task group recently changed the frame mesh multicast/broadcast frame format to use 3-address. This was done to avoid interactions with widely deployed lazy-WDS access points. This patch changes the format of group addressed frames, both mesh-originated and proxied, to use the data format defined in draft D2.08 and forward. The address fields used for group addressed frames is: In 802.11 header ToDS:0 FromDS:1 addr1: DA (broadcast/multicast address) addr2: TA addr3: Mesh SA In address extension header: addr4: SA (only present if frame was proxied) Note that this change breaks backward compatibility with earlier mesh stack versions.

In order for userspace to be able to figure out whether it obtained a consistent snapshot of data or not when using netlink dumps, we need to have a generation number in each dump message that indicates whether the list has changed or not -- its value is arbitrary. This patch adds such a number to all dumps, this needs some mac80211 involvement to keep track of a generation number to start with when adding/removing mesh paths or stations. The wiphy and netdev lists can be fully handled within cfg80211, of course, but generation numbers need to be stored there as well.

Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

We forgot to cancel all timers in mac80211 when suspending. In particular we forgot to deal with some things that can cause hardware reconfiguration -- while it is down. While at it we go ahead and add a warning in ieee80211_sta_work() if its run while the suspend->resume cycle is in effect. This should not happen and if it does it would indicate there is a bug lurking in either mac80211 or mac80211 drivers. With this now wpa_supplicant doesn't blink when I go to suspend and resume where as before there where issues with some timers running during the suspend->resume cycle. This caused a lot of incorrect assumptions and would at times bring back the device in an incoherent, but mostly recoverable, state. Signed-off-by: NLuis R.
