Add a new regulatory flag that allows a driver to manage regdomain changes/updates for its own wiphy. A self-managed wiphys only employs regulatory information obtained from the FW and driver and does not use other cfg80211 sources like beacon-hints, country-code IEs and hints from other devices on the same system. Conversely, a self-managed wiphy does not share its regulatory hints with other devices in the system. If a system contains several devices, one or more of which are self-managed, there might be contradictory regulatory settings between them. Usage of flag is generally discouraged. Only use it if the FW/driver is incompatible with non-locally originated hints. A new API lets the driver send a complete regdomain, to be applied on its wiphy only. After a wiphy-specific regdomain change takes place, usermode will get a new type of change notification. The regulatory core also takes care enforce regulatory restrictions, in case some interfaces are on forbidden channels.

Add the necessary feature flags and a scan flag to support using random MAC addresses for scan while unassociated. The configuration for this supports an arbitrary MAC address value and mask, so that any kind of configuration (e.g. fixed OUI or full 46-bit random) can be requested. Full 46-bit random is the default when no other configuration is passed. Also add a small helper function to use the addr/mask correctly. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Add a new NL80211_CH_SWITCH_STARTED_NOTIFY message that can be sent to the userspace when a channel switch process has started. This allows userspace to take action, for instance, by requesting other interfaces to switch channel as necessary. This patch introduces a function that allows the drivers to send this notification. It should be used when the driver starts processing a channel switch initiated by a remote device (eg. when a STA receives a CSA from the AP) and when it successfully starts a userspace-triggered channel switch (eg. when hostapd triggers a channel swith in the AP).

A mandatory parameters during the ocb_join operation are 'center frequency' and 'channel width (5/10 MHz)'.

During the review of the corresponding wpa_supplicant patches we noticed that the only way for it to detect that this functionality is supported currently is to check for the command support. This can be misleading though, as the command was also designed to, in the future, support pure 802.11 TSPECs. Expose the WMM-TSPEC feature flag to nl80211 so later we can also expose an 802.11-TSPEC feature flag (if needed) to differentiate the two cases. Note: this change isn't needed in 3.18 as there's no driver there yet that supports the functionality at all. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

There are a few possible cases of where BSS data came from: 1) only a beacon has been received 2) only a probe response has been received 3) the driver didn't report what it received (this happens when using cfg80211_inform_bss[_width]()) 4) both probe response and beacon data has been received Unfortunately, in the userspace API, a few things weren't there: a) there was no way to differentiate cases 1) and 4) above without comparing the data of the IEs b) the TSF was always from the last frame, instead of being exposed for beacon/probe response separately like IEs Fix this by i) exporting a new flag attribute that indicates whether or not probe response data has been received - this addresses (a) ii) exporting a BEACON_TSF attribute that holds the beacon's TSF if a beacon has been received iii) not exporting the beacon attributes in case (3) above as that would just lead userspace into thinking the data actually came from a beacon when that isn't clear To implement this, track inside the IEs struct whether or not it (definitely) came from a beacon.

In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation. But, memory get allocated under spin_lock_bh(), this implies atomic context. So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake), and it should be this way or warning triggered in the memory allocation code. Remove @gfp parameter as no actual choice exist, and use hard coded GFP_ATOMIC for memory allocation.

Currently, cfg80211 tries to implement ethtool, but that doesn't really scale well, with all the different operations. Make the lower-level driver responsible for it, which currently only has an effect on mac80211. It will similarly not scale well at that level though, since mac80211 also has many drivers.

Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The firmware / low level driver can parse the channel in the DS IE or HT IE and compensate the RSSI so that it will still have a valid value even if we heard the frame on an adjacent channel. This can be done up to a certain offset. Add this offset as a configuration for the low level driver. A low level driver that can compensate the low RSSI in this case should assign the maximal offset for which the RSSI value is still valid.
