Commit mac80211: avoid using synchronize_rcu in ieee80211_set_probe_resp changed the return value when the probe response template is not present.

In multi-channel scenarios, the channel that we will transmit a probe request on isn't always the current channel (which will be NULL anyway) but will instead be the channel that the AP is on. Pass the channel to the ieee80211_send_probe_req() function so it can be used in the different scenarios. The scan code continues to pass the current channel, of course.

The optimisation of scanning only on the current channel should check the operating channel. Also modify it to compare channel pointer rather than the frequency. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Even for single-channel devices it is possible that we switch the channel temporarily (e.g. for scanning) but while doing so process a received frame that was still received on the old channel, so checking the current band is racy. Use the band from status instead. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

With the move to multi-channel and away from drv_config(), hw.conf.channel will not always be set, only for devices using the current API instead of the new channel context APIs. Check the channel is set before adding its frequency to the trace data. Also break some overly long lines in the code. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Using hw.conf.channel is wrong as it could be the temporary channel if the station is added from the workqueue while the device is already on another channel. Use oper_channel instead. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Using local->_oper_channel_type in the mesh code is completely wrong as this value is the combination of the various interface channel types and can be a different value from the mesh interface in case there are multiple virtual interfaces. Use sdata->vif.bss_conf.channel_type instead as it tracks the per-vif channel type. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Some devices like the current iwlwifi implementation require that the P2P interface address match the P2P Device address (only one P2P interface is supported.) Add the HW flag IEEE80211_HW_P2P_DEV_ADDR_FOR_INTF that allows drivers to request that P2P Interfaces added while a P2P Device is active get the same MAC address by default.

After cfg80211 got a P2P Device abstraction, add support to mac80211. Whether it really is supported or not will depend on whether or not the driver has support for it, but mac80211 needs to change to be able to support drivers that need a P2P Device. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
-
由 Johannes Berg 提交于
In order to support using a different MAC address for the P2P Device address we must first have a P2P Device abstraction that can be assigned a MAC address. This abstraction will also be useful to support offloading P2P operations to the device, e.g. periodic listen for discoverability. Currently, the driver is responsible for assigning a MAC address to the P2P Device, but this could be changed by allowing a MAC address to be given to the NEW_INTERFACE command. As it has no associated netdev, a P2P Device can only be identified by its wdev identifier but the previous patches allowed using the wdev identifier in various APIs, e.g. remain-on-channel.

In IBSS it is possible that the supported rates set for a station changes over time (e.g. it gets first initialised as an empty set because of no available information about rates and updated later). In this case the driver has to be notified about the change in order to update its internal table accordingly (if needed). This behaviour is needed by all those drivers that handle rc internally but leave stations management to mac80211 Reported-by: NGui Iribarren <gui@altermundi.net> Signed-off-by: NAntonio Quartulli <ordex@autistici.org> [Johannes - add docs, validate IBSS mode only, fix compilation] Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

This could take a while (100ms+) and may delay sending assoc resp in AP mode with WPS or P2P GO (as setting the probe resp takes place there).

When sending probe requests, e.g. during software scanning, these will go out on the *current* channel, so their IEs need to be built from the current channel. At other times, e.g. for beacons or probe request templates, the IEs will be used on the *operating* channel and using the current channel instead might result in errors. Add the appropriate parameters to respect the difference. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
