cfg80211: fix scheduled scan pointer access

2013-10-21T09:59:15Z

Since rdev->sched_scan_req is dereferenced outside the lock protecting it, this might be done at the wrong time, causing crashes. Move the dereference to where it should be - inside the RTNL locked section. Cc: stable@vger.kernel.org [3.8+] Reviewed-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

nl80211: add scan width to bss and scan request structs

2013-07-16T06:58:01Z

To allow scanning and working with 5 MHz and 10 MHz BSS, extend the inform bss commands and add wrappers to take 5 and 10 MHz bss into account. Signed-off-by: Simon Wunderlich Signed-off-by: Mathias Kretschmer Signed-off-by: Johannes Berg

wireless: add comments about bss refcounting

cfg80211: vastly simplify locking

2013-05-24T22:02:15Z

Virtually all code paths in cfg80211 already (need to) hold the RTNL. As such, there's little point in having another four mutexes for various parts of the code, they just cause lock ordering issues (and much of the time, the RTNL and a few of the others need thus be held.) Simplify all this by getting rid of the extra four mutexes and just use the RTNL throughout. Only a few code changes were needed to do this and we can get rid of a work struct for bonus points.

cfg80211: move cfg80211_get_dev_from_ifindex under wext

2013-05-24T22:02:13Z

The function is only used and needed by the wext code for scanning, so move it there. Signed-off-by: Johannes Berg

cfg80211: always check for scan end on P2P device

2013-03-24T10:15:58Z

If a P2P device wdev is removed while it has a scan, then the scan completion might crash later as it is already freed by that time. To avoid the crash always check the scan completion when the P2P device is being removed for some reason. If the driver already canceled it, don't want and free it, otherwise warn and leak it to avoid later crashes. In order to do this, locking needs to be changed away from the rdev mutex (which can't always be guaranteed). For now, use the sched_scan_mtx instead, I'll rename it to just scan_mtx in a later patch. Signed-off-by: Johannes Berg

cfg80211: fix potential BSS memory leak and update

2013-03-07T11:55:32Z

In the odd case that while updating information from a beacon, a BSS was found that is part of a hidden group, we drop the new information. In this case, however, we leak the IE buffer from the update, and erroneously update the entry's timestamp so it will never time out. Fix both these issues.

nl80211/cfg80211: add radar detection command/event

2013-02-15T08:40:18Z

Add new NL80211_CMD_RADAR_DETECT, which starts the Channel Availability Check (CAC). This command will also notify the usermode about events (CAC finished, CAC aborted, radar detected, NOP finished). Once radar detection has started it should continuously monitor for radars as long as the channel is active. This patch enables DFS for AP mode in nl80211/cfg80211.
