* ath9k_htc: Add a sanity check in ath9k_htc_ampdu_action()Dan Carpenter2017-12-141-0/+4
| | | | | | | | | | | | | | | Smatch generates a warning here: drivers/net/wireless/ath/ath9k/htc_drv_main.c:1688 ath9k_htc_ampdu_action() error: buffer overflow 'ista->tid_state' 8 <= 15 I don't know if it's a real bug or not but the other paths through this function all ensure that "tid" is less than ATH9K_HTC_MAX_TID (8) so checking here makes things more consistent.

* | cfg80211: remove enum ieee80211_bandJohannes Berg2016-04-121-6/+6
|/ | | | | | | | | 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.

* mac80211: pass block ack session timeout to to driverSara Sharon2016-01-141-3/+4
| | | | | | | | | | | | Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session.

| | | | | | | | | | | | | | | | | | | | | | | current code will handle -ETIMEDOUT as success which is probalbly wrong. According to this comment I assume it is safe to handle -ETIMEDOUT as false: drivers/net/wireless/ath/ath9k/calib.c 290 /* 291 * We timed out waiting for the noisefloor to load, probably due to an 292 * in-progress rx.

We need to avoid 294 * trying to load -50 (which happens below) while the previous load is 295 * still in progress as this can cause rx deafness. Instead by returning 296 * here, the baseband nf cal will just be capped by our present 297 * noisefloor until the next calibration timer. 298 */ Since no other error wariants are present, this patch is checking only for (ret <= 0).

| | | | | | | | | | | | | | | | | | | | | | | | mac80211 ->sta_rc_update() callback must be atomic. Since we have to take mutex and do other operations that can sleep when sending fimrware commands to device, the only option to satisfy atomicity requirement of ->sta_rc_update(), that I can see, is introduce work_struct and defer uploading new rates to that work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sta_rc_update() callback must be atomic, hence we can not take mutexes or do other operations, which can sleep in ath9k_htc_sta_rc_update(). I think we can just return from ath9k_htc_sta_rc_update(), if it is called without IEEE80211_RC_SUPP_RATES_CHANGED bit. That will help with scheduling while atomic bug for most cases (except mesh and IBSS modes). For mesh and IBSS I do not see other solution like creating additional workqueue, because sending firmware command require us to sleep, but this can be done in additional patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | When TX aggregation is stopped, there are a few different cases: - connection with the peer was dropped - session stop was requested locally - session stop was requested by the peer - connection was dropped while a session is stopping The behaviour in these cases should be different, if the connection is dropped then the driver should drop all frames, otherwise the frames may continue to be transmitted, aggregated in the case of a locally requested session stop or unaggregated in the case of the peer requesting session stop. Split these different cases so that the driver can act accordingly; however, treat local and remote stop the same way and ask the driver to not send frames as aggregated packets any more. In the case of connection drop, the stop callback the driver is otherwise supposed to call is no longer required. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
