2011-11-09mac80211: fix race between connection monitor & suspendJohannes Berg
When the connection monitor timer fires right before suspend, the following will happen: timer fires -> monitor_work gets queued suspend calls ieee80211_sta_quiesce ieee80211_sta_quiesce: - deletes timer - cancels monitor_work synchronously, running it [note wrong order of these steps] monitor_work runs, re-arming the timer later, timer fires while system should be quiesced This causes a warning: WARNING: at net/mac80211/util.c:540 ieee80211_can_queue_work+0x35/0x40 [mac80211]() but is otherwise harmless.

2011-10-03mac80211: Send nullfunc frames at lower rate during connection monitorRajkumar Manoharan
Recently mac80211 was changed to use nullfunc instead of probe request for connection monitoring for tx ack status reporting hardwares. Sometimes in congested network, STA got disconnected quickly after the association. It was observered that the rate control was not adopted to environment due to minimal transmission. As the nullfunc are used for monitoring purpose, these frames should not be sacrificed for rate control updation. So it is better to send the monitoring null func frames at minimum rate that could help to retain the connection. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

When adding a TDLS peer STA, mark it with a new flag in both nl80211 and mac80211. Before adding a peer, make sure the wiphy supports TDLS and our operating mode is appropriate (managed). In addition, make sure all peers are removed on disassociation. A TDLS peer is first added just before link setup is initiated.

The hw.conf.channel value is not updated properly for drivers that support HW channel switch.

2011-09-14mac80211: stop tx before doing hw config and rate updateRajkumar Manoharan
The assumption is that during the hw config, transmission was already stopped by mac80211. Sometimes the AP can be switching b/w the ht modes due to intolerant or etc where STA is in the middle of transmission. In such scenario, buffer overflow was observed at driver side. And also before updating the rate control, the frames are continued to xmited with older rates. This patch ensures that the frames are always xmitted with updated rates and avoid buffer overflow.

2011-08-26mac80211: fix race condition between assoc_done and first EAP packetGuy Eilam
When associating to an AP, the station might miss the first EAP packet that the AP sends due to a race condition between the association success procedure and the rx flow in mac80211. In such cases, the packet might fall in ieee80211_rx_h_check due to the fact that the relevant rx->sta wasn't allocated yet. Allocation of the relevant station info struct before actually sending the association request and setting it with a new dummy_sta flag solve this problem. The station will accept only EAP packets from the AP while it is in the pre-association/dummy state. This dummy station entry is not seen by normal sta_info_get() calls, only by sta_info_get_bss_rx(). The driver is not notified for the first insertion of the dummy station. The driver is notified only after the association is complete and the dummy flag is removed from the station entry. That way, all the rest of the code flow should be untouched by this change.

2011-07-13mac80211: allow driver to disconnect after resumeJohannes Berg
In WoWLAN, devices may use crypto keys for TX/RX and could also implement GTK rekeying. If the driver isn't able to retrieve replay counters and similar information from the device upon resume, or if the device isn't responsive due to platform issues, it isn't safe to keep the connection up as GTK rekey messages from during the sleep time could be replayed against it. The only protection against that is disconnecting from the AP. Modifying mac80211 to do that while it is resuming would be very complex and invasive in the case that the driver requires a reconfig, so do it after it has resumed completely. In that case, however, packets might be replayed since it can then only happen after TX/RX are up again, so mark keys for interfaces that need to disconnect as "tainted" and drop all packets that are sent or received with those keys.

2011-04-12mac80211: Check for queued frames before entering power save.Vivek Natarajan
In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops.

It also may result in a failed 4-way handshake depending on the AP's timing requirements and beacon interval, and the station's listen interval.

2011-02-23mac80211: Fix a race on enabling power save.Vivek Natarajan
There is a race on sending a data frame before the tx completion of nullfunc frame for enabling power save. As the data quickly follows the nullfunc frame, the AP thinks that the station is out of power save and continues to send the frames. Whereas in the station, the nullfunc ack will be processed after the tx completion of data frame and mac80211 goes to powersave. Thus the power save state mismatch between the station and the AP causes some data loss and some applications fail because of that. This patch fixes this issue.

Low level driver could pass rx frames to us after disassociate, what can lead to run conn_mon_timer by ieee80211_sta_rx_notify(). That is obviously wrong, but nothing happens until we unload modules and resources are used after free.

2011-02-09mac80211: Properly set work-item channel-type.Ben Greear
Some were indirectly set to NO_HT (zero), but I think it's better to explicitly set it in case the enum ever changes. In cfg.c, it seems the channel-type was just ignored (and thus always set to NO_HT). Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-02-07mac80211: Make some mlme timers module paramaters.Ben Greear
This allows users to tune the connection-loss algorithms to be more or less lenient. In particular, larger null-func retries helps when using lots of virtual stations on a loaded network. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-02-03mac80211: Warn users if HT fails because of freq mismatch.Ben Greear
I have a netgear WNDR3700 that appears to have an off-by-four bug in how it fills out the hti->control_chan (I configure the AP to channel 11, it reports 15 as control_chan). Poke a message into the kernel logs to give users a clue as to why they are not getting the expected channel-type or rate. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W.

2011-01-31mac80211: disable power save if an infra AP vif existsRajkumar Manoharan
PS should not be enabled if an infra AP vif exists in the interface list. So while recalculating PS, AP vif type should be taken into account.

2011-01-21cfg80211: Extend channel to frequency mapping for 802.11jBruno Randolf
Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping channel numbers in the 2GHz and 5GHz band we can't map from channel to frequency without knowing the band. This is no problem as in most contexts we know the band. In places where we don't know the band (and WEXT compatibility) we assume the 2GHz band for channels below 14. This patch does not implement all channel to frequency mappings defined in 802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz channels as well as 802.11y channels have been omitted. The following drivers have been updated to reflect the API changes: iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx. The drivers have been compile-tested only.
