Saqeb Akhter reported frequent disconnects while streaming videos over samba: <http://marc.info/?m=128600031109136> > [ 1166.512087] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7) > [ 1526.059997] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7) > [ 2125.324356] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7) > [...] The reason is that the device generates frames with slightly bogus SA/TA addresses. e.g.: [ 2314.402316] Ignore 9f:1f:31:f8:64:ff [ 2314.402321] Ignore 9f:1f:31:f8:64:ff [ 2352.453804] Ignore 0d:1f:31:f8:64:ff [ 2352.453808] Ignore 0d:1f:31:f8:64:ff ^^ the group-address flag is set! (the correct SA/TA would be: 00:1f:31:f8:64:ff) Since the AP does not know from where the frames come, it generates a DEAUTH response for the (invalid) mcast address. This mcast deauth frame then passes through all filters and tricks the stack into thinking that the AP brutally kicked us! This patch fixes the problem by simply ignoring non-broadcast, group-addressed deauth/disassoc frames.

| * mac80211: Fix frame injection using non-AP vifJouni Malinen2010-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for frame injection to work properly for some use cases (e.g., finding the station entry and keys for encryption), mac80211 needs to find the correct sdata entry. This works when the main vif is in AP mode, but commit a2c1e3dad516618cb0fbfb1a62c36d0b0744573a broke this particular use case for station main vif. While this type of injection is quite unusual operation, it has some uses and we should fix it. Do this by changing the monitor vif sdata selection to allow station vif to be selected instead of limiting it to just AP vifs. We still need to skip some iftypes to avoid selecting unsuitable vif for injection. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | mac80211: use nullfunc instead of probe request for connection monitoringFelix Fietkau2010-11-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nullfunc frames are better for connection monitoring, because probe requests are answered even if the AP has already dropped the connection, whereas nullfunc frames from an unassociated station will trigger a disassoc/deauth frame from the AP (WLAN_REASON_CLASS3_FRAME_FROM_NONASSOC_STA), which allows the station to reconnect immediately instead of waiting until it attempts to transmit the next unicast frame. This only works on hardware with reliable tx ACK reporting, any other hardware needs to fall back to the probe request method. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

| * mac80211: unset SDATA_STATE_OFFCHANNEL when cancelling a scanBrian Cavagnolo2010-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For client STA interfaces, ieee80211_do_stop unsets the relevant interface's SDATA_STATE_RUNNING state bit prior to cancelling an interrupted scan. When ieee80211_offchannel_return is invoked as part of cancelling the scan, it doesn't bother unsetting the SDATA_STATE_OFFCHANNEL bit because it sees that the interface is down. Normally this doesn't matter because when the client STA interface is brought back up, it will probably issue a scan. But in some cases (e.g., the user changes the interface type while it is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This prevents the interface queues from being started. So we cancel the scan before unsetting the SDATA_STATE_RUNNING bit. Signed-off-by: Brian Cavagnolo <brian@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | mac80211: Disable hw crypto for GTKs on AP VLAN interfacesHelmut Schaa2010-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using AP VLAN interfaces, each VLAN interface should be in its own broadcast domain. Hostapd achieves this by assigning different GTKs to different AP VLAN interfaces. However, mac80211 drivers are not aware of AP VLAN interfaces and as such mac80211 sends the GTK to the driver in the context of the base AP mode interface. This causes problems when multiple AP VLAN interfaces are used since the driver will use the same key slot for the different GTKs (there's no way for the driver to distinguish the different GTKs from different AP VLAN interfaces). Thus, only the clients associated to one AP VLAN interface (the one that was created last) can actually use broadcast traffic. Fix this by not programming any GTKs for AP VLAN interfaces into the hw but fall back to using software crypto. The GTK for the underlying AP interface is still sent to the driver. That means, broadcast traffic to stations associated to an AP VLAN interface is encrypted in software whereas broadcast traffic to stations associated to the non-VLAN AP interface is encrypted in hardware.

* | mac80211: fix powersaving clients racesJohannes Berg2010-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code to handle powersaving stations has a race: when the powersave flag is lifted from a station, we could transmit a packet that is being processed for TX at the same time right away, even if there are other frames queued for it. This would cause frame reordering. To fix this, lift the flag only under the appropriate lock that blocks TX. Additionally, the code to allow drivers to block a station while frames for it are on the HW queue is never re-enabled the station, so traffic would get stuck indefinitely. Fix this by clearing the flag for this appropriately. Finally, as an optimisation, don't do anything if the driver unblocks an already unblocked station.

* | mac80211: Add function to get probe request template for current APJuuso Oikarinen2010-11-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chipsets with hardware based connection monitoring need to autonomically send directed probe-request frames to the AP (in the event of beacon loss, for example.) For the hardware to be able to do this, it requires a template for the frame to transmit to the AP, filled in with the BSSID and SSID of the AP, but also the supported rate IE's. This patch adds a function to mac80211, which allows the hardware driver to fetch this template after association, so it can be configured to the hardware.

* mac80211: fix failure to check kmalloc return value in key_key_readJesper Juhl2010-10-29
| | | | | | | | | | | | | | | | | | I noticed two small issues in mac80211/debugfs_key.c::key_key_read while reading through the code. Patch below. The key_key_read() function returns ssize_t and the value that's actually returned is the return value of simple_read_from_buffer() which also returns ssize_t, so let's hold the return value in a ssize_t local variable rather than a int one. Also, memory is allocated dynamically with kmalloc() which can fail, but the return value of kmalloc() is not checked, so we may end up operating on a null pointer further on. So check for a NULL return and bail out with -ENOMEM in that case. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

The ampdu_len field of the tx status is not always initialized for non-HT frames (and it would probably be unreasonable to require all drivers to do so). This could cause rate control statistics to be corrupted. We now trust the ampdu_len and ampdu_ack_len fields only when the frame is marked with the IEEE80211_TX_STAT_AMPDU flag. 2. Successful transmission attempts where only recognized when the A-MPDU subframe carrying the rate control status information was marked with the IEEE80211_TX_STAT_ACK flag. If this information happed to be carried on a frame that failed to be ACKed then the other subframes (which may have succeeded) where not correctly registered. We now update rate control statistics regardless of whether the subframe carrying the information was ACKed or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since this small buffer isn't used for DMA, we can simply allocate it on the stack, it just needs to be 16 bytes of which only 8 will be used for WEP40 keys.

| | * | | mac80211: temporarily disable reorder release timerChristian Lamparter2010-10-11

A lengthy discussion - which lists some of the pitfalls and possible solutions - can be found at: http://marc.info/?t=128635927000001 But due to the complicated nature of the subject and the imminent advent of a new -rc cycle, it was decided to disable the feature for the time being.

| | * | | mac80211: fix possible null-pointer de-referenceChristian Lamparter2010-10-11

The original bug was detected by smatch. ( http://repo.or.cz/w/smatch.git ) net/mac80211/mesh_plink.c +574 mesh_rx_plink_frame(168) error: we previously assumed 'sta' could be null.
