| | | | | | | | | | | | | sta_info_cleanup locks the sta_list using rcu_read_lock however the delete operation isn't rcu safe. A race between sta_info_cleanup timer being called and a STA being removed can occur which leads to a panic while traversing sta_list. Fix this by switching to the RCU-safe versions.

* mac80211: clean up remain-on-channel on interface stopJohannes Berg2012-06-04
| | | | | | | | | | | | | | | | | | When any interface goes down, it could be the one that we were doing a remain-on-channel with. We therefore need to cancel the remain-on-channel and flush the related work structs so they don't run after the interface has been removed or even destroyed. It's also possible in this case that an off-channel SKB was never transmitted, so free it if this is the case. Note that this can also happen if the driver finishes the off-channel period without ever starting it.

* mac80211: Fix Unreachable Mesh Station Problem when joining to another MBSSChun-Yeow Yeoh2012-06-04
| | | | | | | | | | | | | | | Mesh station that joins an MBSS is reachable using mesh portal with 6 address frame by mesh stations from another MBSS if these two different MBSSes are bridged. However, if the mesh station later moves into the same MBSS of those mesh stations, it is unreachable by mesh stations in the MBSS due to the mpp_paths table is not deleted. A quick fix is to perform mesh_path_lookup, if it is available for the target destination, mpp_path_lookup is not performed. When the mesh station moves back to its original MBSS, the mesh_paths will be deleted once expired. So, it will be reachable using mpp_path_lookup again.

* mac80211: Fix race in checking AP status by sending null frameSoumik Das2012-05-25
| | | | | | | | | | | | | | | mac80211 tries to verify the existence of the current AP by probing or sending a NULL frame in function ieee80211_mgd_probe_ap_send. It 1st sends a null frame to the AP, increments probe_send_count and waits for the ACK to the NULL frame for a finite duration of time. At times, it happens that by the time mac80211 gets to increment probe_send_count, the ACK for the NULL frame transmitted has already been processed. This leads to a race condition where mac80211 times out waiting for the ACK for the NULL frame causing unnecessary disconnection with the AP.

Three HT protection modes are supported for now: non-HT mixed mode - is selected if any non-HT peers are present in our MBSS. 20MHz-protection mode - is selected if all peers in our 20/40MHz MBSS support HT and atleast one HT20 peer is present. no-protection mode - is selected otherwise. This is a limited implementation of 9.23.3.5, which only considers mesh peers when determining the HT protection mode. Station's channel_type needs to be maintained.

| * | mac80211: fix num_mcast_sta counting issuesFelix Fietkau2012-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Moving a STA to an AP VLAN prevents num_mcast_sta from being decremented once the STA leaves, because sta->sdata changes. Fix this by checking for AP VLANs as well. Also exclude 4-addr VLAN stations from num_mcast_sta - remote 4-addr stations ignore 3-address multicast frames anyway. In a typical bridge configuration they receive the same packets as 4-address unicast. This patch also fixes clearing the sdata->u.vlan.sta pointer when the STA is removed from a 4-addr VLAN.
