| | * mac80211: Don't restart sta-timer if not associated.Ben Greear2013-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found another crash when deleting lots of virtual stations in a congested environment. I think the problem is that the ieee80211_mlme_notify_scan_completed could call ieee80211_restart_sta_timer for a stopped interface that was about to be deleted. With the following patch I am unable to reproduce the crash.

| | * cfg80211: always check for scan end on P2P deviceJohannes Berg2013-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <johannes.berg@intel.com>
| | * mac80211: fix virtual monitor interface lockingJohannes Berg2013-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The virtual monitor interface has a locking issue, it calls into the channel context code with the iflist mutex held which isn't allowed since it is usually acquired the other way around. The mutex is still required for the interface iteration, but need not be held across the channel calls. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| | * cfg80211: fix wdev tracing crashJohannes Berg2013-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Arend reported a crash in tracing if the driver returns an ERR_PTR() value from the add_virtual_intf() callback. This is due to the tracing then still attempting to dereference the "pointer", fix this by using IS_ERR_OR_NULL().

| | * mac80211: fix crash with P2P Device returning action framesJohannes Berg2013-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a P2P Device interface receives an unhandled action frame, we attempt to return it. This crashes because it doesn't have a channel context. Fix the crash by using status->band and properly mark the return frame as an off-channel frame.

| | * cfg80211: fix potential BSS memory leak and updateJohannes Berg2013-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * mac80211: always synchronize_net() during station removalJohannes Berg2013-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there are keys left during station removal, then a synchronize_net() will be done (for each key, I have a patch to address this for 3.10), otherwise it won't be done at all which causes issues because the station could be used for TX while it's being removed from the driver -- that might confuse the driver. Fix this by always doing synchronize_net() if no key was present any more. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * | | | Bluetooth: Handle AD updating through an async requestJohan Hedberg2013-03-18

This patch changes the hci_update_ad() function to take a request pointer and updates its users appropriately. E.g. the function is no longer called after the init sequence but during stage 3 of the init sequence. The TX power is read during the init sequence, so we don't need an explicit update whenever it is read and the AD update based on the local name should be done through the local name mgmt handler. The only other user is the update based on enabling advertising. This part is still kept as there is no mgmt API to enable it.

| * | | | Bluetooth: Fix waiting for EIR update when setting local nameJohan Hedberg2013-03-18

This patch fixes the issue by running the local name HCI command and the EIR update in the same asynchronous request, and returning the mgmt command complete through the complete callback of the request. The downside of this is that we must set hdev->dev_name before the local name HCI command has completed since otherwise the generated EIR command doesn't contain the new name. This means that we can no-longer reliably detect when the name has really changed and when not. Luckily this only affects scenarios where the mgmt interface is *not* used (e.g. hciconfig) so redundant mgmt_ev_local_name_changed events in these cases are an acceptable drawback.
