2013-08-26mac80211: fix change_interface queue assignmentsJohannes Berg
Jouni reported that with mac80211_hwsim, multicast TX was causing crashes due to invalid vif->cab_queue assignment. It turns out that this is caused by change_interface() getting invoked and not having the vif->type/vif->p2p assigned correctly before calling the queue check (ieee80211_check_queues). Fix this by passing the 'external' interface type to the function and adjusting it accordingly. While at it, also fix the error path in change_interface, it wasn't correctly resetting to the external type but using the internal one instead. Fortunately this affects on hwsim because all other drivers set the vif->type/vif->p2p variables when changing iftype. This shouldn't be needed, but almost all implementations actually do it for their own internal handling. Reported-by: Jouni Malinen <j@w1.fi> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-08-23mac80211: ignore (E)CSA in probe response framesJohannes Berg
Seth reports that some APs, notably the Netgear WNDAP360, send invalid ECSA IEs in probe response frames with the operating class and channel number both set to zero, even when no channel switch is being done. As a result, any scan while connected to such an AP results in the connection being dropped. Fix this by ignoring any channel switch announcment in probe response frames entirely, since we're connected to the AP we will be receiving a beacon (and maybe even an action frame) if a channel switch is done, which is sufficient.

According to 802.11-2012 9.3.2.10, paragraph 4, QoS data frames with a group address in the Address 1 field have sequence numbers allocated from the same counter as non-QoS data and management frames.

2013-08-23mac80211: move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into driversJohannes Berg
mac80211 currently sets WIPHY_FLAG_SUPPORTS_SCHED_SCAN based on whether the start_sched_scan operation is supported or not, but that will not be correct for all drivers, we're adding scheduled scan to the iwlmvm driver but it depends on firmware support. Therefore, move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into the drivers so that they can control it regardless of implementing the operation. This currently only affects the TI drivers since they're the only ones implementing scheduled scan (in a mac80211 driver.)

2013-08-16mac80211: add APIs to allow keeping connections after WoWLANJohannes Berg
In order to be able to (securely) keep connections alive after the system was suspended for WoWLAN, we need some additional APIs. We already have API (ieee80211_gtk_rekey_notify) to tell wpa_supplicant about the new replay counter if GTK rekeying was done by the device while the host was asleep, but that's not sufficient. If GTK rekeying wasn't done, we need to tell the host about sequence counters for the GTK (and PTK regardless of rekeying) that was used while asleep, add ieee80211_set_key_rx_seq() for that. If GTK rekeying was done, then we need to be able to disable the old keys (with ieee80211_remove_key()) and allocate the new GTK key(s) in mac80211 (with ieee80211_gtk_rekey_add()). If protocol offload (e.g. ARP) is implemented, then also the TX sequence counter for the PTK must be updated, using the new ieee80211_set_key_tx_seq() function.

2013-08-16mac80211: perform power save processing before decryptionJohan Almbladh
This patch decouples the power save processing from the frame decryption by running the decrypt rx handler after sta_process. In the case where the decryption failed for some reason, the stack used to not process the PM and MOREDATA bits for that frame. The stack now always performs power save processing regardless of the decryption result. That means that encrypted data frames and NULLFUNC frames are now handled in the same way regarding power save processing, making the stack more robust.

In case the AP has different regulatory information than we do, it can happen that we connect to an AP based on e.g. the world roaming regulatory data, and then update our database with the AP's country information disables the channel the AP is using. If this happens on an HT AP, the bandwidth tracking code will hit the WARN_ON() and disconnect. Since that's not very useful, ignore the channel-disable flag in bandwidth tracking.

2013-07-31mac80211: ignore HT primary channel while connectedJohannes Berg
While we're connected, the AP shouldn't change the primary channel in the HT information. We checked this, and dropped the connection if it did change it. Unfortunately, this is causing problems on some APs, e.g. on the Netgear WRT610NL: the beacons seem to always contain a bad channel and if we made a connection using a probe response (correct data) we drop the connection immediately and can basically not connect properly at all. Work around this by ignoring the HT primary channel information in beacons if we're already connected. Also print out more verbose messages in the other situations to help diagnose similar bugs quicker in the future.

2013-07-22mac80211: prevent the buffering or frame transmission to non-assoc mesh STAChun-Yeow Yeoh
This patch is intended to avoid the buffering to non-assoc mesh STA and also to avoid the triggering of frame to non-assoc mesh STA which could cause kernel panic in specific hw. One of the examples, is kernel panic happens to ath9k if user space inserts the mesh STA and not proceed with the SAE and AMPE, and later the same mesh STA is detected again. The sta_state of the mesh STA remains at IEEE80211_STA_NONE and if the ieee80211_sta_ps_deliver_wakeup is called and subsequently the ath_tx_aggr_wakeup, the kernel panic due to ath_tx_node_init is not called before to initialize the require data structures.
