Set DFS CAC time also in case of using custom and strict regulatory from drivers. In other case we could have unset DFS CAC time directly after driver loaded and before issue regulatory set from user mode.

When looking for a BSS matching given parameters, ignore invalid BSSIDs. This avoids, for example, trying to join an IBSS that has a multicast BSSID, which isn't supported by all drivers nor is it a valid configuration of the IBSS so better create a new one with a correctly chosen random BSSID.

With single-channel drivers, we need to be able to change a running chanctx if we want to use chanctx reservation. Not all drivers may be able to do this, so add a flag that indicates support for it. Changing a running chanctx can also be used as an optimization in multi-channel drivers when the context needs to be reserved for future usage. Introduce IEEE80211_CHANCTX_RESERVED chanctx mode to mark a channel as reserved so nobody else can use it (since we know it's going to change). In the future, we may allow several vifs to use the same reservation as long as they plan to use the chanctx on the same future channel.

In order to support channel switch with multiple vifs and multiple contexts, we implement a concept of channel context reservation. This allows us to reserve a channel context to be used later. The reservation functionality is not tied directly to channel switch and may be used in other situations (eg. reserving a channel context during IBSS join). We first check if an existing compatible context exists and if it does, we reserve it. If there is no compatible context we create a new one and reserve it. Additionally, split ieee80211_vif_copy_chanctx_to_vlans() so we can call it while already holding the chanctx mutex.

Combine the functions into one, so that we can switch from one context to the other without having to unassign and assign separately. This is needed by the channel reservation functionality because otherwise we have a small period of time when the chanctx is set to NULL, which can cause problems if someone else is trying to dereference it.

ieee80211_vif_change_channel() locks chanctx_mtx.

It was impossible to change chanctx of master AP for AP VLANs because the copy function requires RTNL which can't be simply taken in mac80211 code due to possible deadlocks. This is required for future chanctx reservation that re-bind vifs to new chanctx. This requires safe AP VLAN iteration without RTNL. Now VLANs can be iterated while holding either RTNL or local->mtx because the list is modified while holding both of these locks.

Get rid of the cfg80211_can_add_interface() and cfg80211_can_change_interface() functions by moving that functionality to mac80211. With this patch all interface combination checks are now out of cfg80211 (except for the channel switch case which will be addressed in a future commit). Additionally, modify the ieee80211_check_combinations() function so that an undefined chandef can be passed, in order to use it before a channel is defined.

Allow GO operation on a channel marked with IEEE80211_CHAN_GO_CONCURRENT iff there is an active station interface that is associated to an AP operating on the same channel in the 2 GHz band or the same UNII band (in the 5 GHz band). This relaxation is not allowed if the channel is marked with IEEE80211_CHAN_RADAR. Note that this is a permissive approach to the FCC definitions, that require a clear assessment that the device operating the AP is an authorized master, i.e., with radar detection and DFS capabilities. It is assumed that such restrictions are enforced by user space. Furthermore, it is assumed, that if the conditions that allowed for the operation of the GO on such a channel change, i.e., the station interface disconnected from the AP, it is the responsibility of user space to evacuate the GO from the channel.

The FCC are clarifying some soft configuration requirements, which among other include the following: 1. Indoor operation, where a device can use channels requiring indoor operation, subject to that it can guarantee indoor operation, i.e., the device is connected to AC Power or the device is under the control of a local master that is acting as an AP and is connected to AC Power. 2. Concurrent GO operation, where devices may instantiate a P2P GO while they are under the guidance of an authorized master. For example, on a channel on which a BSS is connected to an authorized master, i.e., with DFS and radar detection capability in the UNII band.

Wdev->ssid_len has already been set in cfg80211_connect() and is equal to connect->ssid_len. Use wdev->ssid_len instead of connect->ssid_len so it will be consistent with previous ssid assignment statement. If bss is found in cfg80211_get_conn_bss(), wdev->conn->state is set to CFG80211_CONN_AUTHENTICATE_NEXT in there. So it's not needed to set it manually to CFG80211_CONN_AUTHENTICATE_NEXT if bss is found in that function.

When dynamically creating interfaces from userspace, e.g. for P2P usage, such interfaces are usually owned by the process that created them, i.e. wpa_supplicant. Should wpa_supplicant crash, such interfaces will often cease operating properly and cause problems on restarting the process. To avoid this problem, introduce an ownership concept for interfaces. If an interface is owned by a netlink socket, then it will be destroyed if the netlink socket is closed for any reason, including if the process it belongs to crashed. This gives us a race-free way to get rid of any such interfaces. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
