| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since cfg80211 frequently takes actions from its netdev notifier call, wireless extensions messages could still be ordered badly since the wext netdev notifier, since wext is built into the kernel, runs before the cfg80211 netdev notifier. For example, the following can happen: 5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff 5: wlan1: <BROADCAST,MULTICAST,UP> link/ether when setting the interface down causes the wext message. To also fix this, export the wireless_nlevent_flush() function and also call it from the cfg80211 notifier. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | | wext: fix message delay/orderingJohannes Berg2016-01-291-11/+40

It turns out that the message is a wireless extensions message, which was sent because the interface had been connected and disconnection while it was deleted caused a wext message. For its netlink messages, wext uses RTM_NEWLINK, but the message is without all the regular rtnetlink attributes, so "ip monitor link" prints just rudimentary information: 5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff Deleted 5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff 5: wlan1: <BROADCAST,MULTICAST,UP> link/ether (from my hwsim reproduction) This can cause userspace to get confused since it doesn't expect an RTM_NEWLINK message after RTM_DELLINK. The reason for this is that wext schedules a worker to send out the messages, and the scheduling delay can cause the messages to get out to userspace in different order. To fix this, have wext register a netdevice notifier and flush out any pending messages when netdevice state changes. This fixes any ordering whenever the original message wasn't sent by a notifier itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a new station is added to AP/GO interfaces the default behaviour is for it to be added authenticated and associated, due to backwards compatibility. To prevent that, the driver must be able to do that (setting the NL80211_FEATURE_FULL_AP_CLIENT_STATE feature flag) and userspace must set the flag mask to auth|assoc and clear the set. Handle this quirk in the API entirely in nl80211, and always push the full flags to the drivers. NL80211_FEATURE_FULL_AP_CLIENT_STATE is still required for userspace to be allowed to set the mask including those bits, but after checking that add both flags to the mask and set in case userspace didn't set them otherwise. This obsoletes the mac80211 code handling this difference, no other driver is currently using these flags. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | 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.)

| * cfg80211: allow changing station capabilities for unassociated stationsAyala Beker2015-09-291-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, cfg80211 rejects capability updates for existing entries and as a result it's impossible to update entries that were added unassociated, but that is necessary to go through the full station states from userspace, adding a station before authentication etc. Fix this by allowing updates to capabilities for stations that the driver (or mac80211) assigned unassociated state. Drivers setting the full station state support flag must use the new station type for proper operation.

| * net/wireless: enable wiphy device to suspend/resume asynchronouslyFu, Zhonghui2015-09-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Now, PM core supports asynchronous suspend/resume mode for devices during system suspend/resume, and the power state transition of one device may be completed in separate kernel thread. PM core ensures all power state transition timing dependency between devices. This patch enables wiphy device to suspend/resume asynchronously. This can take advantage of multicore and improve system suspend/resume speed. Signed-off-by: Zhonghui Fu <zhonghui.fu@linux.intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * nl80211: put current TX power in interface infoRafał Miłecki2015-09-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | Many drivers implement reading current TX power (using either cfg80211 or ieee80211 op) but userspace can't get it using nl80211. Right now the only way to access it is to call some wext ioctl. Let's put TX power in interface info reply (callback is wdev specific) just like we do with current channel. To be consistent (e.g. NL80211_CMD_SET_WIPHY) let's use mBm as na unit. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
