Currently, cfg80211 will copy beacon IEs from a previously received hidden SSID beacon to a probe response entry, if that entry is created after the beacon entry. However, if it is the other way around, or if the beacon is updated, such changes aren't propagated. Fix this by tracking the relation between the probe response and beacon BSS structs in this case. In case drivers have private data stored in a BSS struct and need access to such data from a beacon entry, cfg80211 now provides the hidden_beacon_bss pointer from the probe response entry to the beacon entry.

In per-station statistics, present 32bit counters are too small for practical purposes - with gigabit speeds, it get overlapped every few seconds. Expand counters in the struct station_info to be 64-bit. Driver can still fill only 32-bit and indicate in @filled only bits like STATION_INFO_[TR]X_BYTES; in case driver provides full 64-bit counter, it should also set in @filled bit STATION_INFO_[TR]RX_BYTES64 Netlink sends both 32-bit and 64-bit counters, if present, to not break userspace.

Add API to enable drivers to implement MAC address based access control in AP/P2P GO mode. Capable drivers advertise this capability by setting the maximum number of MAC addresses in such a list in wiphy->max_acl_mac_addrs. An initial ACL may be given to the NL80211_CMD_START_AP command and/or changed later with NL80211_CMD_SET_MAC_ACL. Black- and whitelists are supported, but not simultaneously.

As per email discussion Jouni Malinen pointed out that: "P2P message exchanges can be executed on the current operating channel of any operation (both P2P and non-P2P station). These can be on 5 GHz and even on 60 GHz (so yes, you _can_ do GO Negotiation on 60 GHz). As an example, it would be possible to receive a GO Negotiation Request frame on a 5 GHz only radio and then to complete GO Negotiation on that band. This can happen both when connected to a P2P group (through client discoverability mechanism) and when connected to a legacy AP (assuming the station receive Probe Request frame from full scan in the beginning of P2P device discovery)." This means that P2P messages can be sent over different radio devices. However, these should use the same P2P device address so it should be able to provision this from user-space. This patch adds a parameter for this to struct vif_params which should only be used during creation of the P2P device interface.

Add power_mode entry to the mesh config structure to hold the user-configured default mesh power mode. This value will be used for new peer links. Add the dot11MeshAwakeWindowDuration value to the mesh config. The awake window is a duration in TU describing how long the STA will stay awake after transmitting its beacon in PS mode. Add access routines to: - get/set local link-specific power mode (STA) - get remote STA's link-specific power mode (STA) - get remote STA's non-peer power mode (STA) - get/set default mesh power mode (mesh config) - get/set mesh awake window duration (mesh config) All config changes may be done at mesh runtime and take effect immediately.

Change nl80211 to support specifying a VHT (or HT) using the control channel frequency (as before) and new attributes for the channel width and first and second center frequency. The old channel type is of course still supported for HT. Also change the cfg80211 channel definition struct to support these by adding the relevant fields to it (and removing the _type field.) This also adds new helper functions: - cfg80211_chandef_create to create a channel def struct given the control channel and channel type, - cfg80211_chandef_identical to check if two channel definitions are identical - cfg80211_chandef_compatible to check if the given channel definitions are compatible, and return the wider of the two This isn't entirely complete, but that doesn't matter until we have a driver using it. In particular, it's missing - regulatory checks on the usable bandwidth (if that even makes sense) - regulatory TX power (database can't deal with it) - a proper channel compatibility calculation for the new channel types Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Instead of passing a channel pointer and channel type to all functions and driver methods, pass a new channel definition struct. Right now, this struct contains just the control channel and channel type, but for VHT this will change.

As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.

The function cfg80211_get_p2p_attr() can fail and returns a negative error code. However, the return type is unsigned int.

The NL80211_CMD_TDLS_OPER command was previously used only for userspace request for the kernel code to perform TDLS operations. However, there are also cases where the driver may need to request operations from userspace, e.g., when using security on the AP path. Add a new cfg80211 function for generating a TDLS operation event for drivers to request a new link to be set up (NL80211_TDLS_SETUP) or an existing link to be torn down (NL80211_TDLS_TEARDOWN). Drivers can optionally use these events, e.g., based on noticing data traffic being sent to a peer station that is seen with good signal strength.

Parsing the P2P attributes can be tricky as their contents can be split across multiple (vendor) IEs. Thus, it's not possible to parse them like IEs (by returning a pointer to the data.)

Allow drivers (and mac80211) to advertise support for per-interface TX power configuration.
