* cfg80211: allow AID/listen interval changes for unassociated stationAyala Beker2015-11-031-9/+18
| | | | | | | | | | | | | | | Currently, cfg80211 rejects updates of AID and listen interval parameters for existing entries. This information is known only at association stage and as a result it's impossible to update entries that were added unassociated. Fix this by allowing updates of these properies for stations that the driver (or mac80211) assigned unassociated state. This then fixes mac80211's use of NL80211_FEATURE_FULL_AP_CLIENT_STATE.

* cfg80211: Add multiple scan plans for scheduled scanAvraham Stern2015-10-133-15/+170
| | | | | | | | | | | | | | | | | | | | | | | Add the option to configure multiple 'scan plans' for scheduled scan. Each 'scan plan' defines the number of scan cycles and the interval between scans. The scan plans are executed in the order they were configured. The last scan plan will always run infinitely and thus defines only the interval between scans. The maximum number of scan plans supported by the device and the maximum number of iterations in a single scan plan are advertised to userspace so it can configure the scan plans appropriately. When scheduled scan results are received there is no way to know which scan plan is being currently executed, so there is no way to know when the next scan iteration will start. This is not a problem, however. The scan start timestamp is only used for flushing old scan results, and there is no difference between flushing all results received until the end of the previous iteration or the start of the current one, since no results will be received in between.

* nl80211: allow BSS data to include CLOCK_BOOTTIME timestampDmitry Shmidt2015-10-134-39/+47
| | | | | | | | | | | | | | | | | | | For location and connectivity services, userspace would often like to know the time when the BSS was last seen. The current "last seen" value is calculated in a way that makes it less useful, especially if the system suspended in the meantime. Add the ability for the driver to report a real CLOCK_BOOTTIME stamp that can then be reported to userspace (if present). Drivers wishing to use this must be converted to the new API to call cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They need to ensure the reported value is accurate enough even when the frame might have been buffered in the device (e.g. firmware.)

This also enables improvements to other drivers, like ath6kl, that would like to sleep in this callback.

| * cfg80211: wext: clear sinfo struct before calling driverJohannes Berg2015-06-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until recently, mac80211 overwrote all the statistics it could provide when getting called, but it now relies on the struct having been zeroed by the caller. This was always the case in nl80211, but wext used a static struct which could even cause values from one device leak to another. Using a static struct is OK (as even documented in a comment) since the whole usage of this function and its return value is always locked under RTNL. Not clearing the struct for calling the driver has always been wrong though, since drivers were free to only fill values they could report, so calling this for one device and then for another would always have leaked values from one to the other. Fix this by initializing the structure in question before the driver method call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we disconnect from the AP, drivers call cfg80211_disconnect().

This issue obviously doesn't show up with any mac80211 based driver since mac80211 doesn't call this function. Fix this by requiring drivers to indicate whether the disconnect is locally generated or not. I've tried to update the drivers, but may not have gotten the values correct, and some drivers may currently not be able to report correct values. In case of doubt I left it at false, which is the current behaviour. For libertas, make adjustments as indicated by Dan Williams.

* cfg80211: Stop calling crda if it is not responsiveIlan peer2015-04-013-7/+38
| | | | | | | | | | | | | | | Patch eeca9fce1d71a4955855ceb0c3b13c1eb9db27c1 (cfg80211: Schedule timeout for all CRDA call) introduced a regression, where in case that crda is not installed (or not configured properly etc.), the regulatory core will needlessly continue to call it, polluting the log with the following log: "cfg80211: Calling CRDA to update world regulatory domain" Fix this by limiting the number of continuous CRDA request failures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

| * cfg/mac80211: add regulatory classes IE during TDLS setupArik Nemtsov2015-03-301-0/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Seems Broadcom TDLS peers (Nexus 5, Xperia Z3) refuse to allow TDLS connection when channel-switching is supported but the regulatory classes IE is missing from the setup request. Add a chandef to reg-class translation function to cfg80211 and use it to add the required IE during setup. For now add only the current regulatory class as supported - it is enough to resolve the compatibility issue.

| * cfg80211: Process all pending regulatory requests/hintsBen2015-03-171-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | It is possible that there are several regulatory requests pending, but the processing of the last one does not call CRDA, and thus the other requests are not handled. Fix this by rescheduling the work until all requests have been processed.
