* mac80211: add stations after AP start on reconfigArik Nemtsov2012-06-061-7/+30
| | | | | | | | | | | | When performing a HW restart for an AP mode interface, add stations back only after the AP is beaconing. This mimics the normal flow of STA addition on AP. Some devices (wlcore) do not support adding stations before beaconing, so this has the added benefit of making recovery work for them.

* cfg80211: validate remain-on-channel time betterJohannes Berg2012-06-062-7/+18
| | | | | | | | | | | | | | | | The remain-on-channel time validation shouldn't depend on the value of HZ, as it does now with the check against jiffies, since then you might use a value that works on one system but not on another. Fix it by checking against a minimum that's fixed. Also add validation of the wait duration for a management frame TX since this also translates into remain-on-channel internally.

* mac80211: Clear wowlan flag when drv_suspend returns failurePontus Fuchs2012-06-061-0/+1
| | | | | | | | | | | | | | | | drv_resume can get called without a prior call to drv_suspend. Consider the following steps: 1. Suspend is started but driver's drv_suspend returns error. 2. Suspend is aborted. local->wowlan flag is left set. 3. Interface is removed. 4. Suspend again. This time open_count is 0 so drv_suspend is not called and local->wowlan not cleared. 5. On resume ieee80211_reconfig will call drv_resume since local->wowlan is set. Signed-off-by: Pontus Fuchs <pontus.fuchs@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* rfkill: Add the capability to switch all devices of all type in ↵Alex Hung2012-06-061-1/+1
| | | | | | | | | | | | | | __rfkill_switch_all(). __rfkill_switch_all() switches the state of devices of a given type; however, it does not switch devices of all type (RFKILL_TYPE_ALL). As a result, it ignores the keycode "KEY_RFKILL" from another module, i.e. eeepc-wmi.

| * | iwlwifi: fix double free/complete in firmware loadingJohannes Berg2012-06-051-2/+7
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linus reported that due to mac80211 failing to register the device (due to WoWLAN) his machine crashed etc. as we double-freed the vmalloc() firmware area. His patch to fix it was very similar to this one but I noticed that there's another bug in the area: we complete the completion before starting, so since we're running in a work struct context stop() could be called while in the middle of start() which will almost certainly lead to issues. Make a modification similar to his to avoid the double- free but also move the completion to another spot so it is only done after start() either finished or failed so that stop() can have a consistent state.

| * mac80211: clean up remain-on-channel on interface stopJohannes Berg2012-06-042-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When any interface goes down, it could be the one that we were doing a remain-on-channel with. We therefore need to cancel the remain-on-channel and flush the related work structs so they don't run after the interface has been removed or even destroyed. It's also possible in this case that an off-channel SKB was never transmitted, so free it if this is the case. Note that this can also happen if the driver finishes the off-channel period without ever starting it.

| * mac80211: Fix Unreachable Mesh Station Problem when joining to another MBSSChun-Yeow Yeoh2012-06-041-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mesh station that joins an MBSS is reachable using mesh portal with 6 address frame by mesh stations from another MBSS if these two different MBSSes are bridged. However, if the mesh station later moves into the same MBSS of those mesh stations, it is unreachable by mesh stations in the MBSS due to the mpp_paths table is not deleted. A quick fix is to perform mesh_path_lookup, if it is available for the target destination, mpp_path_lookup is not performed. When the mesh station moves back to its original MBSS, the mesh_paths will be deleted once expired. So, it will be reachable using mpp_path_lookup again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CFG80211_DEV_WARN_ON() at "net/wireless/ibss.c line 63" is unnecessarily triggered even after successful connection, when cfg80211_ibss_joined() is called by driver inside .join_ibss handler. This patch fixes the problem by changing 'sme_state' in ibss path and having WARN_ON() check for 'sme_state' similar to infra association.
