| | | | | | | | | | | Set the spectrum management bit in the hw flags so that mac80211 will set the WLAN_CAPABILITY_SPECTRUM_MGMT bit in association requests (which in practice means that we support 802.11h spectrum management).

* wl12xx: Don't filter beacons that include changed HT IEsShahar Levi2011-05-121-2/+6
| | | | | | | | | | | This patch adds a beacon filter rule to pass up the beacons that contain changed HT information elements. These beacons need to be passed to mac80211 so that it can act on such changes.

* cfg80211/mac80211: avoid bounce back mac->cfg->mac on sched_scan_stoppedLuciano Coelho2011-05-128-30/+43
| | | | | | | | | | | | | | | | | When sched_scan_stopped was called by the driver, mac80211 calls cfg80211, which in turn was calling mac80211 back with a flag "driver_initiated". This flag was used so that mac80211 would do the necessary cleanup but would not call the driver. This was enough to prevent the bounce back between the driver and mac80211, but not between mac80211 and cfg80211. To fix this, we now do the cleanup in mac80211 before calling cfg80211. To help with locking issues, the workqueue was moved from cfg80211 to mac80211.

* mac80211: fix another key non-raceJohannes Berg2011-05-121-2/+4
| | | | | | | | | | | | The code here is only not racy because all the places that assign the pointers it uses are holding the sta_mtx as well as the key_mtx and so can't race against this because this code holds the sta_mtx. But that's not intuitive, so fix it to hold the key_mtx. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: make key locking clearerJohannes Berg2011-05-123-27/+20Star
| | | | | | | | | | | | | The code in ieee80211_del_key() doesn't acquire the key_mtx properly when it dereferences the keys. It turns out that isn't actually necessary since the key_mtx itself seems to be redundant since all key manipulations are done under the RTNL, but as long as we have the key_mtx we should use it the right way too.

* mac80211: remove pointless mesh path timer RCU codeJohannes Berg2011-05-121-14/+3Star
| | | | | | | | | | | | | | | The code here to RCU-dereference a pointer that's on the stack is totally pointless, RCU isn't magic (like say Java's weak references are), so the code can't work like whoever wrote it thought it might. Remove it so readers don't get confused. Note that it seems that a bug is there anyway: I don't see any code that cancels the timer when a mesh path struct is destroyed.

| | | | | | | | | | | | | | | | | The XB113 cards are single band, 5 GHz-only, but the default settings were configured to assume it was dual band. Users of these cards then would see 2.4 GHz channels but you would never get any scan results from these channels given that the radio is not present.

* mac80211: fix contention time computation in minstrel, minstrel_htDaniel Halperin2011-05-122-8/+23
| | | | | | | | | | When transmitting a frame, the transmitter waits a random number of slots between 0 and cw. Thus, the contention time is (cw / 2) * t_slot which we can represent instead as (cw * t_slot) >> 1. Also fix a few other accounting bugs around contention time, and add comments.

That means, it's not possible to re-authenticate the link if you already have combination key and for instance want to re-authenticate to get the high security (use 16 digit pin). Therefore, it's necessary to check security requirements on auth complete event to prevent not enough secure connection.

Add NL80211_CMD_START_SCHED_SCAN and NL80211_CMD_STOP_SCHED_SCAN commands to the nl80211 interface. When results are available they are reported by NL80211_CMD_SCHED_SCAN_RESULTS events. The userspace is informed when the scheduled scan has stopped with a NL80211_CMD_SCHED_SCAN_STOPPED event, which can be triggered either by the driver or by a call to NL80211_CMD_STOP_SCHED_SCAN.
