mac80211: add ieee80211_is_any_nullfunc()

2020-05-10T08:26:36+00:00

commit 30b2f0be23fb40e58d0ad2caf8702c2a44cda2e1 upstream. commit 08a5bdde3812 ("mac80211: consider QoS Null frames for STA_NULLFUNC_ACKED") Fixed a bug where we failed to take into account a nullfunc frame can be either non-QoS or QoS. It turns out there is at least one more bug in ieee80211_sta_tx_notify(), introduced in commit 7b6ddeaf27ec ("mac80211: use QoS NDP for AP probing"), where we forgot to check for the QoS variant and so assumed the QoS nullfunc frame never went out Fix this by adding a helper ieee80211_is_any_nullfunc() which consolidates the check for non-QoS and QoS nullfunc frames. Replace existing compound conditionals and add a couple more missing checks for QoS variant.

mac80211: ignore tx status for PS stations in ieee80211_tx_status_ext

2018-12-13T08:21:37+00:00

commit a317e65face482371de30246b6494feb093ff7f9 upstream. Make it behave like regular ieee80211_tx_status calls, except for the lack of filtered frame processing. This fixes spurious low-ack triggered disconnections with powersave clients connected to an AP.

mac80211: Always report TX status

2018-11-10T15:41:33+00:00

[ Upstream commit 8682250b3c1b75a45feb7452bc413d004cfe3778 ] If a frame is dropped for any reason, mac80211 wouldn't report the TX status back to user space. As the user space may rely on the TX_STATUS to kick its state machines, resends etc, it's better to just report this frame as not acked instead.

mac80211: don't parse encrypted management frames in ieee80211_frame_acked

2018-03-24T09:58:44+00:00

[ 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: move station statistics into sub-structs

2015-10-21T08:08:22+00:00

Group station statistics by where they're (mostly) updated (TX, RX and TX-status) and group them into sub-structs of the struct sta_info. Also rename the variables since the grouping now makes it obvious where they belong. This makes it easier to identify where the statistics are updated in the code, and thus easier to think about them. Signed-off-by: Johannes Berg

mac80211: remove sta->last_ack_signal

2015-10-21T08:08:21+00:00

This file only feeds a debugfs file that isn't very useful, so remove it. If necessary, we can add other ways to get this information, for example in the NL80211_CMD_PROBE_CLIENT response. Signed-off-by: Johannes Berg
