2019-10-01ath9k_htc: Discard undersized packetsMasashi Honma
Sometimes the hardware will push small packets that trigger a WARN_ON in mac80211. Discard them early to avoid this issue. This patch ports 2 patches from ath9k to ath9k_htc. commit 3c0efb745a172bfe96459e20cbd37b0c945d5f8d "ath9k: discard undersized packets". commit df5c4150501ee7e86383be88f6490d970adcf157 "ath9k: correctly handle short radar pulses".

2018-06-29ath9k: use irqsave() in USB's complete callbackSebastian Andrzej Siewior
The USB completion callback does not disable interrupts while acquiring the lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives.

2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg

In v3.15 the driver stopped to accept network packets after successful authentification, which could be worked around by passing the nohwcrypt=1 module parameter. This was not reproducible by everyone, and showed random behaviour in some tests. It was caused by an uninitialized variable introduced in 4ed1a8d4a257 ("ath9k_htc: use ath9k_cmn_rx_accept") and used in 341b29b9cd2f ("ath9k_htc: use ath9k_cmn_rx_skb_postprocess").

Ether_addr_equal_64bits is more efficient than ether_addr_equal, and can be used when each argument is an array within a structure that contains at least two bytes of data beyond the array. The structures involved are: ieee80211_hdr defined in include/linux/ieee80211.h ath_common defined in drivers/net/wireless/ath/ath.h This was done using Coccinelle (http://coccinelle.lip6.fr/).

2013-08-22ath9k_htc: Restore skb headroom when returning skb to mac80211Helmut Schaa
ath9k_htc adds padding between the 802.11 header and the payload during TX by moving the header. When handing the frame back to mac80211 for TX status handling the header is not moved back into its original position. This can result in a too small skb headroom when entering ath9k_htc again (due to a soft retransmission for example) causing an skb_under_panic oops. Fix this by moving the 802.11 header back into its original position before returning the frame to mac80211 as other drivers like rt2x00 or ath5k do.

2013-02-27ath9k_htc: fix signal strength handling issuesFelix Fietkau
The ath9k commit 2ef167557c0a26c88162ecffb017bfcc51eb7b29 (ath9k: fix signal strength reporting issues) fixed an issue where the reported per-frame signal strength reported to mac80211 was being overwritten with an internal average. The same issue is also present in ath9k_htc. In addition to preventing the driver from overwriting the value, this commit also ensures that the internal average (which is used for ANI) only tracks beacons of the AP that we're connected to.
