* iwlwifi: mvm: remove pointless scan plan checksJohannes Berg2015-10-25
| | | | | | | | As cfg80211 already enforces these limits, there's little point in having them again here in our code. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

* iwlwifi: mvm: Implement per vif frame registration APIAndrei Otcheretianski2015-10-25
| | | | | | | | | | | Implement config_iface_filter() driver op. Currently support only probe request registration for p2p client vifs, by setting MAC_FILTER_IN_PROBE_REQUEST flag in MAC_CONTEXT_CMD. This is needed since WFDS spec and certification require a P2P client to be discoverable on its operating channel.

* iwlwifi: avoid read/write operations if the bus is deadEliad Peller2015-10-25
| | | | | | | | | | Recovery takes too much time if the bus is dead (each timeout is 2000ms, etc.). Explicitly skip fw dump in this case, as it will result in garbage data (and might take signifcant time) Signed-off-by: Eliad Peller <eliadx.peller@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
* iwlwifi: mvm: Add support for two scheduled scan plansAvraham Stern2015-10-25
| | | | | | | | | Add support for two scan plans for scheduled scan. The first plan will run for a limited number of iterations, then the second plan will run infinitely. Signed-off-by: Avraham Stern <avraham.stern@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
* iwlwifi: mvm: let any command flag be passed to iwl_mvm_flushtx_path()Luca Coelho2015-10-25
| | | | | | | | | | Instead of only allowing the caller to decide whether the CMD_ASYNC flag is set, let it pass the entire flags bitmask. This allows more flexibility and will be needed when we call this function in the suspend flow (where other flags are needed).

* iwlwifi: mvm: use short timeouts in P2P low latency if supportedJohannes Berg2015-10-25
| | | | | | | | | | | Those timeouts are used for AM-to-PSM transition. We already have those pairs defined for default and WOWLAN use cases. We expect that by using shorter threshold for low latency P2P, e.g. for Miracast video scenario, we might save a considerable amount of power.

| | | | | | | | | | | The hardware bug in the commit mentioned below forces us not to re-enable the clock gating in the Host Cluster. The impact on the power consumption is minimal and it allows the WAKE_ME interrupt to propagate.

| * mac80211: move station statistics into sub-structsJohannes Berg2015-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Group station statistics by where they're (mostly) updated (TX, RX and TX-status) and group them into sub-structs of the struct sta_info. Also rename the variables since the grouping now makes it obvious where they belong. This makes it easier to identify where the statistics are updated in the code, and thus easier to think about them. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211: move beacon_loss_count into ifmgdJohannes Berg2015-10-21
| | | | | | | | | | | | | | | | | | | | There's little point in keeping (and even sending to userspace) the beacon_loss_count value per station, since it can only apply to the AP on a managed-mode connection. Move the value to ifmgd, advertise it only in managed mode, and remove it from ethtool as it's available through better interfaces. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211: remove sta->last_ack_signalJohannes Berg2015-10-21
| | | | | | | | | | | | | | | | This file only feeds a debugfs file that isn't very useful, so remove it. If necessary, we can add other ways to get this information, for example in the NL80211_CMD_PROBE_CLIENT response. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * cfg80211: reg: centralize freeing ignored requestsJohannes Berg2015-10-16
| | | | | | | | | | | | | | | | | | | | | | | | Instead of having a lot of places that free ignored requests and then return REG_REQ_OK, make reg_process_hint() process REG_REQ_IGNORE by freeing the request, and let functions it calls return that instead of freeing. This also fixes a leak when a second (different) country IE hint was ignored. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * cfg80211: reg: make CRDA support optionalJohannes Berg2015-10-16
| | | | | | | | | | | | | | | | If there's a built-in regulatory database, there may be little point in also calling out to CRDA and failing if the system is configured that way. Allow removing CRDA support to save ~1K kernel size. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * cfg80211: reg: remove useless reg_timeout schedulingJohannes Berg2015-10-15
| | | | | | | | | | | | | | | | | | | | | | When the functions reg_set_rd_driver() and reg_set_rd_country_ie() return with an error, the calling function already restores data by calling restore_regulatory_settings(), so there's no need to also schedule a timeout (which would lead to other side effects such as indicating CRDA failed, which clearly isn't true.) Remove the scheduling. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * cfg80211: reg: search built-in database directlyJohannes Berg2015-10-15
| | | | | | | | | | | | | | | | | | Instead of searching the built-in database only in the worker, search it directly and return an error if the entry cannot be found (or memory cannot be allocated.) This means that builtin database queries no longer rely on the timeout. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * cfg80211: reg: rename reg_call_crda to reg_query_databaseJohannes Berg2015-10-15
| | | | | | | | | | | | | | The new name is more appropriate since in the case of a built-in database it may not really rely on CRDA. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * cfg80211: reg: fix reg_call_crda() return value bugJohannes Berg2015-10-15
| | | | | | | | | | | | | | | | The function reg_call_crda() can't actually validly return REG_REQ_IGNORE as it does now when calling CRDA fails since that return value isn't handled properly. Fix that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * cfg80211: reg: remove useless non-NULL checkJohannes Berg2015-10-15

| * mac80211: remove PM-QoS listenerJohannes Berg2015-10-14
| | | | | | | | | | | | | | | | | | | | As this API has never really seen any use and most drivers don't ever use the value derived from it, remove it. Change the only driver using it (rt2x00) to simply use the DTIM period instead of the "max sleep" time. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * mac80211: Do not restart scheduled scan if multiple scan plans are setAvraham Stern2015-10-13
| | | | | | | | | | | | | | | | | | | | | | | | If multiple scan plans were set for scheduled scan, do not restart scheduled scan on reconfig because it is possible that some scan plans were already completed and there is no need to run them all over again. Instead, notify userspace that scheduled scan stopped so it can configure new scan plans for scheduled scan.

| * cfg80211: Add multiple scan plans for scheduled scanAvraham Stern2015-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Shmidt2015-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it's possible for someone to send a vlan range to the kernel with the pvid flag set which will result in the pvid bouncing from a vlan to vlan and isn't correct, it also introduces problems for hardware where it doesn't make sense having more than 1 pvid. iproute2 already enforces this, so let's enforce it on kernel-side as well.

In netfilter and af_packet we defragment packets in the output path, and there is the usual amount of confusion about how to compute which net we are processing the packets in.
