2012-02-01mac80211: timeout a single frame in the rx reorder bufferEliad Peller
The current code checks for stored_mpdu_num > 1, causing the reorder_timer to be triggered indefinitely, but the frame is never timed-out (until the next packet is received) Signed-off-by: Eliad Peller <eliad@wizery.com> Cc: <stable@vger.kernel.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2012-01-30mac80211: Move num_sta_ps counter decrement after synchronize_rcuHelmut Schaa
Unted the assumption that the sta struct is still accessible before the synchronize_rcu call we should move the num_sta_ps counter decrement after synchronize_rcu to avoid incorrect decrements if num_sta_ps.

2012-01-30mac80211: Fix incorrect num_sta_ps decrement in ap_sta_ps_endHelmut Schaa
If the driver blocked this specific STA with the help of ieee80211_sta_block_awake we won't clear WLAN_STA_PS_STA later but still decrement num_sta_ps. Hence, the next data frame from this STA will trigger ap_sta_ps_end again and also decrement num_sta_ps again leading to an incorrect num_sta_ps counter. This can result in problems with powersaving clients not waking up from PS because the TIM calculation might be skipped due to the incorrect num_sta_ps counter.

2012-01-30mac80211: Fix incorrect num_sta_ps decrement in __sta_info_destroyHelmut Schaa
When WLAN_STA_PS_DRIVER is set by ieee80211_sta_block_awake the num_sta_ps counter is not incremented. Hence, we shouldn't decrement it in __sta_info_destroy if only WLAN_STA_PS_DRIVER is set. This could result in an incorrect num_sta_ps counter leading to strange side effects with associated powersaving clients. Fix this by only decrementing num_sta_ps when WLAN_STA_PS_STA was set before.

2012-01-30mac80211: station state transition error handlingJohannes Berg
In the future, when we start notifying drivers, state transitions could potentially fail. To make it easier to distinguish between programming bugs and driver failures: * rename sta_info_move_state() to sta_info_pre_move_state() which can only be called before the station is inserted (and check this with a new station flag). * rename sta_info_move_state_checked() to just plain sta_info_move_state(), as it will be the regular function that can fail for more than just one reason (bad transition or an error from the driver) This makes the programming model easier -- one of the functions can only be called before insertion and can't fail, the other can fail.

2012-01-27mac80211: Do not scan for IBSS merge with a fixed BSSID.Nicolas Cavallari
Currently, when we are on an IBSS network with no active station, we would scan for other BSSID, even if fixed_bssid is on, due to a bug in ibss.c, where fixed_channel would be checked instead of fixed_bssid. This would trigger useless scans where scan results would not be used anyway. This patch also reverts commit 39d02a7d90602d4557ee05db2a157a4e0, which assumed that the ifibss->fixed_channel check was legitimate to disable single-channel scans. IBSS single-channel scan should now be fixed. Signed-off-by: Nicolas Cavallari <cavallar@lri.fr> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-01-24mac80211: set bss_conf.idle when vif is connectedEliad Peller
__ieee80211_recalc_idle() iterates through the vifs, sets bss_conf.idle = true if they are disconnected, and increases "count" if they are not (which later gets evaluated in order to determine whether the device is idle). However, the loop doesn't set bss_conf.idle = false (along with increasing "count"), causing the device idle state and the vif idle state to get out of sync in some cases.

2012-01-24mac80211: in IBSS use the Auth frame to trigger STA reinsertionAntonio Quartulli
In case of a node re-joining the cell the sta_info structure belonging to it is first destroyed and then reinserted. In this way its internal state is reset. The joining operation is recognised thank the Auth frame being received. This operation is helpful in case of a node being rebooted that is joining the ad-hoc cell again, before its purge timeout on other nodes expires.

2012-01-18mac80211: fix work removal on deauth requestJohannes Berg
When deauth is requested while an auth or assoc work item is in progress, we currently delete it without regard for any state it might need to clean up. Fix it by cleaning up for those items. In the case Pontus found, the problem manifested itself as such: authenticate with 00:23:69:aa:dd:7b (try 1) authenticated failed to insert Dummy STA entry for the AP (error -17) deauthenticating from 00:23:69:aa:dd:7b by local choice (reason=2) It could also happen differently if the driver uses the tx_sync callback. We can't just call the ->done() method of the work items because that will lock up due to the locking in cfg80211. This fix isn't very clean, but that seems acceptable since I have patches pending to remove this code completely.

Use local->tx_headroom instad of local->hw.extra_tx_headroom. local->tx_headroom is the max of hw.extra_tx_headroom required by the driver and the headroom required by mac80211 for status reporting. On drivers where hw.extra_tx_headroom is smaller than what mac80211 requires (e.g. ath5k), we would not reserve sufficient buffer space to report tx status.

We may leak the 'fwd_skb' we skb_copy() in ieee80211_rx_h_mesh_fwding() if we take the 'else' branch in the 'if' statement just below. If we take that branch we'll end up returning from the function and since we've not assigned 'fwd_skb' to anything at that point, we leak it when the variable goes out of scope. The simple fix seems to be to just kfree_skb(fwd_skb); just before we return. That is what this patch does. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: John W.

2012-01-13mac80211: fix no-op authorized transitionsJohannes Berg
When userspace attempts to authorize a station that is already authorized, nothing happens as you'd expect. Similarly, when it unauthorizes a station that is associated, nothing happens. However, when it unauthorizes a station that isn't even associated yet, we erroneously try to move the station to associated. This seems to happen occasionally as a result of a race when wpa_supplicant attempts to unauthorize the port in managed mode. Particularly with my new patches to keep stations, it can then move a station into ASSOCIATED state before we have really associated, which is really confusing.

2011-12-21mac80211: Keep skb->piority for relayed frames in AP modeHelmut Schaa
When mac80211 relays a frame from STA1 to STA2 in AP mode it will get re-classified in the tx path. Unfortunately the frame protocol field is always set to ETH_P_8023 while the classification only kicks in for ETH_P_IP. Hence, a high priority frame from STA1 will be send to STA2 as best effort. Instead of running classification on the frame just use the same priority as STA1 did. Do this by adding 256 to the skb->priority to allow cfg80211_classify8021d to shortcut frame classification.
