* | | mac80211: fix RCU warnings in meshJohannes Berg2011-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sparse RCU checking reports two warnings in the mesh path table code. These are due to questionable uses of rcu_dereference. To fix the first one, get rid of mesh_gate_add() and just make mesh_path_add_gate() do the correct deref. To fix the second one, simply remove rcu_dereference() in mesh_gate_del() -- it already gets a proper pointer as indicated by the prototype (no __rcu annotation) and confirmed by the code.

HT may be disabled, making an /a/b/g/n station act like an a/b/g station. HT40 may be disabled forcing the station to be HT20 even if the AP and local hardware support HT40.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers can usually handle fragmented packets much easier when they get the entire list of fragments at once.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers (e.g. ath9k) assume that it's safe to go into low-power mode immediately after the idle state changes.

This code is called for each tx'ed frame and thus it makes sense to reduce its runtime. Do this by calculating the group index by this formula based on the SGI and HT40 flags as well as the stream number: idx = (HT40 * 2 * MINSTREL_MAX_STREAMS) + (SGI * MINSTREL_MAX_STREAMS) + (streams - 1) Hence, the groups are ordered by th HT40 flag first, then by the SGI flag and afterwards by the number of used streams.

Remove the special case for authentication frames to fix the AP shared key side when operating without cooked monitor interfaces -- with cooked monitor the IEEE80211_TX_INTFL_DONT_ENCRYPT also gets set, so we never get here -- an AP never encrypts auth frames.

This would cause broadcast frames to be discarded by peers with which we have a BA session, since their sequence number would fall outside the allowed range. Set No Ack QoS control bits on multicast QoS frames and filter these in de-aggregation code.

* | | mac80211: Avoid filling up mesh preq queue with redundant requestsJavier Cardona2011-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't accept redundant PREQs for a given destination. This fixes a problem under high load: kernel: [20386.250913] mesh_queue_preq: 235 callbacks suppressed kernel: [20386.253335] Mesh HWMP (mesh0): PREQ node queue full kernel: [20386.253352] Mesh HWMP (mesh0): PREQ node queue full (...) The 802.11s protocol has a provision to limit the rate of path requests (PREQs) are transmitted (dot11MeshHWMPpreqMinInterval) but there was no limit on the rate at which PREQs were being queued up. There is a valid reason for queuing PREQs: this way we can even out PREQ bursts. But queueing multiple PREQs for the same destination is useless.

* | | mac80211: verify virtual interfaces in driver APIJohannes Berg2011-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver is never informed about monitor or AP_VLAN interfaces, so whenever we pass those to it later this is a bug. Verify we don't as there are some cases where this could happen. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
