Fix this and add some comments to make it easier to understand the AC-to-UP(pair) mapping. Set the wmm_acm bits (and show WMM debug) even if the driver does not implement conf_tx() handler. In addition, fix the ACM-based AC downgrade code to not use the highest priority in error cases. We need to break the loop to get the correct AC_BK value (3) instead of returning 0 (which would indicate AC_VO). The comment here was not really very useful either, so let's provide somewhat more helpful description of the situation. Since it is very unlikely that the ACM flag would be set for AC_BK and AC_BE, these bugs are not likely to be seen in real life networks. Anyway, better do these things correctly should someone really use silly AP configuration (and to pass some functionality tests, too). Remove the TODO comment about handling ACM. Downgrading AC is perfectly valid mechanism for ACM. Eventually, we may add support for WMM-AC and send a request for a TS, but anyway, that functionality won't be here at the location of this TODO comment.

In case of a STA mac80211's scan function ever returns 0 and queues the scan request. If ieee80211_sta_work is executed and ieee80211_start_scan fails for some reason cfg80211_scan_done will never be called but cfg80211 still thinks the scan was triggered successfully and will refuse any future scan requests due to drv->scan_req not being cleaned up. If a scan is triggered from within the MLME a similar problem appears. If ieee80211_start_scan returns an error, local->scan_req will not be reset and mac80211 will refuse any future scan requests. Hence, in both cases call ieee80211_scan_failed (which notifies cfg80211 and resets local->scan_req) if ieee80211_start_scan returns an error. Signed-off-by: Helmut Schaa Signed-off-by: John W.

There isn't a problem with this commit, but because of other code changes it doesn't work on kernels >= 2.6.28 (works if same/similar change applied on 2.6.27 for example). The issue is as follows: after commit "mac80211: restructure disassoc/deauth flows" in 2.6.28, the call to ieee80211_sta_deauthenticate added by commit e327b847 will not work: because we do sta_info_flush(local, sdata) inside ieee80211_stop (iface.c), all stations in interface are cleared, so when calling ieee80211_sta_deauthenticate->ieee80211_set_disassoc (mlme.c), inside ieee80211_set_disassoc we have this in the beginning: sta = sta_info_get(local, ifsta->bssid); if (!sta) { The !sta check triggers, thus the function returns early and ieee80211_sta_send_apinfo(sdata, ifsta) later isn't called, so wpa_supplicant/userspace isn't notified with SIOCGIWAP. This commit moves deauthentication to before flushing STA info (sta_info_flush), thus the above can't happen and userspace is really notified when interface goes down.

Subsequently, this reduces the number of warnings, too. Thanks to Joe Perches for pointing this out! v3: Ran the whole file through Lindent first... which does most of the work for me. :) Again, thanks to Joe Perches for this. This is my final answer!
