Allow changing to DFS channels if the channel is available for beaconing and userspace controls DFS operation. Channel switch announcement from other stations on DFS channels will be interpreted as radar event. These channels will then be marked as unvailable. Signed-off-by:

To use DFS in IBSS mode, userspace is required to react to radar events. It can inform nl80211 that it is capable of doing so by adding a NL80211_ATTR_HANDLE_DFS attribute when joining the IBSS. This attribute is supplied to let the kernelspace know that the userspace application can and will handle radar events, e.g. by intiating channel switches to a valid channel. DFS channels may only be used if this attribute is supplied and the driver supports it. Driver support will be checked even if a channel without DFS will be initially joined, as a DFS channel may be chosen later. Signed-off-by:

When the driver requests to move to STATIC or DYNAMIC SMPS, we send an action frame to each associated station and reconfigure the channel context / driver. Of course, non-MIMO stations are ignored. The beacon isn't updated. The association response will include the original capabilities. Stations that associate while in non-OFF SMPS mode will get an action frame right after association to inform them about our current state. Note that we wait until the end of the EAPOL. Sending an action frame before the EAPOL is finished can be an issue for a few clients. Clients aren't likely to send EAPOL frames in MIMO anyway. When the SMPS configuration gets more permissive (e.g. STATIC -> OFF), we don't wake up stations that are asleep We remember that they don't know about the change and send the action frame when they wake up. When the SMPS configuration gets more restrictive (e.g. OFF -> STATIC), we set the TIM bit for every sleeping STA. uAPSD stations might send MIMO until they poll the action frame, but this is for a short period of time.

If we have a wiphy with an ISO3166-alpha2 regulatory domain programmed with the strict flag set we wait until the wiphy gets its wiphy->regd programmed before allowing regulatory domains hints other than country IE hints from processing on the wiphy. The existing check however discards the possibility of custom regulatory domains having also used the strict flag and these will not have the wiphy->regd set. Custom strict regulatory domains never set the wiphy->regd though as such currently all regulatory hints other than country IE hints are being ignored on these wiphys. All custom strict regulatory domains set the wiphy with the WIPHY_FLAG_CUSTOM_REGULATORY and use wiphy_apply_custom_regulatory(). Enhance the check for the strict ISO3166-alpha2 regulatory domain case by exempting the WIPHY_FLAG_CUSTOM_REGULATORY case. This will enable other regulatory hints to be processed now for these strict custom regulatory domains. Cc: smihir@qti.qualcomm.com Cc: tushnimb@qca.qualcomm.com Signed-off-by:

Limit the current implementation to a single channel context used by a single vif, thereby avoiding multi-vif/channel complexities. Reuse the main function from AP CSA code, but move a portion out in order to fit the STA scenario. Add a new mac80211 HW flag so we don't break devices that don't support channel switch with channel-contexts. The new behavior will be opt-in. Signed-off-by:

If allowed in a country, these channels typically require DFS so mark them as such. Channel 144 is a bit special, it's coming into use now to allow more VHT 80 channels, but world roaming with passive scanning is acceptable anyway. It seems fairly unlikely that it'll be used as the control channel for a VHT AP, but it needs to be present to allow a full VHT connection to an AP that uses it as one of the secondary channels. Also enable VHT 160 on these channels, and also for channels 36-48 to be able to use VHT 160 there. Signed-off-by: -

Some devices may not be able to report A-MSDUs in single buffers. Drivers for such devices were forced to re-assemble A-MSDUs which would then be eventually disassembled by mac80211. This could lead to CPU cache thrashing and poor performance. Since A-MSDU has a single sequence number all subframes share it. This was in conflict with retransmission/duplication recovery (IEEE802.11-2012: 9.3.2.10). Patch introduces a new flag that is meant to be set for all individually reported A-MSDU subframes except the last one. This ensures the last_seq_ctrl is updated after the last subframe is processed. If an A-MSDU is actually a duplicate transmission all reported subframes will be properly discarded. Signed-off-by:

This function adds the channel switch announcement implementation for the IBSS code. It is triggered by userspace (mac80211/cfg) or by external channel switch announcement, which have to be adopted. Both CSAs in beacons and action frames are supported. As for AP mode, the channel switch is applied after some time. However in IBSS mode, the channel switch IEs are generated in the kernel.

IBSS CSA will require to disconnect if a channel switch fails, but mac80211 should search and re-connect after this disconnect. To allow such usage, split off the ibss disconnect process in a separate function which only performs the disconnect without overwriting nl80211-supplied parameters. Signed-off-by:

Since when we detect beacon lost we do active AP probing (using nullfunc frame or probe request) there is no need to have beacon polling. Flags IEEE80211_STA_BEACON_POLL seems to be used just for historical reasons. Change also make that after we start connection poll due to beacon loss, next received beacon will abort the poll.

If it is needed to disconnect multiple virtual interfaces after (WoWLAN-) suspend, the most obvious approach would be to iterate all interfaces by calling ieee80211_iterate_active_interfaces() and then call ieee80211_resume_disconnect() for each one. This is what the iwlmvm driver does. Unfortunately, this causes a locking dependency from mac80211's iflist_mtx to the key_mtx. This is problematic as the former is intentionally never held while calling any driver operation to allow drivers to iterate with their own locks held. The key_mtx is held while installing a key into the driver though, so this new lock dependency means drivers implementing the logic above can no longer hold their own lock while iterating. To fix this, add a new ieee80211_iterate_active_interfaces_rtnl() function that iterates while the RTNL is already held. This is true during suspend/resume, so that then the locking dependency isn't introduced. While at it, also refactor the various interface iterators and keep only a single implementation called by the various cases. Signed-off-by:
