2014-09-05cfg80211: avoid duplicate entries on regdomain intersectionEliad Peller
The regdom intersection code simply tries intersecting each rule of the source with each rule of the target. Since the resulting intersections are not observed as a whole, this can result in multiple overlapping/duplicate entries. Make the rule addition a bit more smarter, by looking for rules that can be contained within other rules, and adding only extended ones.

2014-04-25cfg80211: Use 5MHz bandwidth by default when checking usable channelsRostislav Lisovy
Current code checks if the 20MHz bandwidth is allowed for particular channel -- if it is not, the channel is disabled. Since we need to use 5/10 MHz channels, this code is modified in the way that the default bandwidth to check is 5MHz. If the maximum bandwidth allowed by the channel is smaller than 5MHz, the channel is disabled. Otherwise the channel is used and the flags are set according to the bandwidth allowed by the channel.

2014-04-22cfg80211: fix processing world regdomain when non modularLuis R. Rodriguez
This allows processing of the last regulatory request when we determine its still pending. Without this if a regulatory request failed to get processed by userspace we wouldn't be able to re-process it later. An example situation that can lead to an unprocessed last_request is enabling cfg80211 to be built-in to the kernel, not enabling CFG80211_INTERNAL_REGDB and the CRDA binary not being available at the time the udev rule that kicks of CRDA triggers. In such a situation we want to let some cfg80211 triggers eventually kick CRDA for us again. Without this if the first cycle attempt to kick off CRDA failed we'd be stuck without the ability to change process any further regulatory domains. cfg80211 will trigger re-processing of the regulatory queue whenever schedule_work(&reg_work) is called, currently this happens when: * suspend / resume * disconnect * a beacon hint gets triggered (non DFS 5 GHz AP found) * a regulatory request gets added to the queue We don't have any specific opportunistic late boot triggers to address a late mount of where CRDA resides though, adding that should be done separately through another patch. Without an opportunistic fix then this fix relies at least one of the triggeres above to happen. Reported-by: Sander Eikelenboom <linux@eikelenboom.it> Signed-off-by: Luis R.

2014-04-09cfg80211: Enable GO operation on additional channelsIlan Peer
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.

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.

2014-03-03cfg80211: allow reprocessing of pending requestsLuis R. Rodriguez
In certain situations we want to trigger reprocessing of the last regulatory hint. One situation in which this makes sense is the case where the cfg80211 was built-in to the kernel, CFG80211_INTERNAL_REGDB was not enabled and the CRDA binary is on a partition not availble during early boot. In such a case we want to be able to re-process the same request at some other point. When we are asked to re-process the same request we need to be careful to not kfree it, addresses that.

2014-02-05cfg80211: regulatory introduce maximum bandwidth calculationJanusz Dziedzic
In case we will get regulatory request with rule where max_bandwidth_khz is set to 0 handle this case as a special one. If max_bandwidth_khz == 0 we should calculate maximum available bandwidth base on all frequency contiguous rules. In case we need auto calculation we just have to set: country PL: DFS-ETSI (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ AUTO), (N/A, 20) (5250 - 5330 @ AUTO), (N/A, 20), DFS (5490 - 5710 @ 80), (N/A, 27), DFS This mean we will calculate maximum bw for rules where AUTO (N/A) were set, 160MHz (5330 - 5170) in example above. So we will get: (5170 - 5250 @ 160), (N/A, 20) (5250 - 5330 @ 160), (N/A, 20), DFS In other case: country FR: DFS-ETSI (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ AUTO), (N/A, 20) (5250 - 5330 @ 80), (N/A, 20), DFS (5490 - 5710 @ 80), (N/A, 27), DFS We will get 80MHz (5250 - 5170): (5170 - 5250 @ 80), (N/A, 20) (5250 - 5330 @ 80), (N/A, 20), DFS Base on this calculations we will set correct channel bandwidth flags (eg. IEEE80211_CHAN_NO_80MHZ). We don't need any changes in CRDA or internal regulatory.
