mac80211: don't parse encrypted management frames in ieee80211_frame_acked

2018-03-24T09:57:33Z

[ Upstream commit cf147085fdda044622973a12e4e06f1c753ab677 ] ieee80211_frame_acked is called when a frame is acked by the peer. In case this is a management frame, we check if this an SMPS frame, in which case we can update our antenna configuration. When we parse the management frame we look at the category in case it is an action frame. That byte sits after the IV in case the frame was encrypted. This means that if the frame was encrypted, we basically look at the IV instead of looking at the category. It is then theorically possible that we think that an SMPS action frame was acked where really we had another frame that was encrypted. Since the only management frame whose ack needs to be tracked is the SMPS action frame, and that frame is not a robust management frame, it will never be encrypted. The easiest way to fix this problem is then to not look at frames that were encrypted.

mac80211: add TDLS connection timeout

2014-09-11T10:18:47Z

Adding a timeout for tearing down a TDLS connection that hasn't had ACKed traffic sent through it for a certain amount of time. Since we have no other monitoring facility to indicate the existance (or non-existance) of a peer, this patch will cause a peer to be considered as unavailable if for some X time at least some Y packets have all not been ACKed.

mac80211: add Intel Mobile Communications copyright

2014-09-05T11:52:06Z

Our legal structure changed at some point (see wikipedia), but we forgot to immediately switch over to the new copyright notice. For files that we have modified in the time since the change, add the proper copyright notice now. Signed-off-by: Johannes Berg Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

Converting time from one format to another seems to give coders a warm and fuzzy feeling. Use the proper interfaces. Signed-off-by: Thomas Gleixner Cc: John Stultz Cc: Peter Zijlstra Cc: John W. Linville [fix compile error] Signed-off-by: Johannes Berg

mac80211: reduce packet loss notifications under load

2014-05-28T14:22:48Z

During strong signal fluctuations under high throughput, few consecutive failed A-MPDU transmissions can easily trigger packet loss notification, and thus (in AP mode) client disconnection. Reduce the number of false positives by checking the A-MPDU status flag and treating a failed A-MPDU as a single packet. Signed-off-by: Felix Fietkau Signed-off-by: Johannes Berg

mac80211: fixup radiotap tx flags for RTS/CTS

2014-04-22T15:08:30Z

When using RTS/CTS, the CTS-to-Self bit in radiotap TX flags is getting set instead of the RTS bit. Set the correct one. Reported-by: Larry Maxwell Signed-off-by: Bob Copeland Signed-off-by: Johannes Berg

mac80211: update last_tx_rate only for data frame

2014-04-09T08:50:45Z

Rate controller in firmware may also return the Tx Rate used for management frame that is usually sent as lowest Tx Rate (1Mbps in 2.4GHz). So update the last_tx_rate only if it is data frame. This patch is tested with ath9k_htc. Signed-off-by: Chun-Yeow Yeoh Signed-off-by: Johannes Berg

mac80211: remove set but unused variables

Compiling with W=1 found a few variables that are set but not used (-Wunused-but-set-variable), remove them. Signed-off-by: Johannes Berg

mac80211: Tx frame latency statistics

2013-12-02T10:51:50Z

Measure TX latency and jitter statistics per station per TID. These Measurements are disabled by default and can be enabled via debugfs. Features included for each station's TID: 1. Keep count of the maximum and average latency of Tx frames. 2. Keep track of many frames arrived in a specific time range (need to enable through debugfs and configure the bins ranges) Signed-off-by: Matti Gottlieb Signed-off-by: Johannes Berg
