* cfg80211: Pass TDLS peer's QoS/HT/VHT information during set_stationJouni Malinen2013-02-151-9/+81
| | | | | | | | | | | | | | | The information of the peer's capabilities is required for the driver to perform TDLS Peer UAPSD operations. This information of the peer is passed by the supplicant using NL80211_CMD_SET_STATION command. This commit enhances the function nl80211_set_station to pass this information of the peer to the driver in case this command is used with the TDLS peer STA. In addition, make the HT/VHT capability configuration handled more consistently for other STA cases (reject both instead of just HT).

* cfg80211: Pass station (extended) capability info to kernelJouni Malinen2013-02-151-0/+36
| | | | | | | | | | | | | | | The information of the peer's capabilities and extended capabilities are required for the driver to perform TDLS Peer UAPSD operations and off channel operations. This information of the peer is passed from user space using NL80211_CMD_SET_STATION command. This commit enhances the function nl80211_set_station to pass the capability information of the peer to the driver. Similarly, there may be need for capability information for other modes, so allow this to be provided with both add_station and change_station.

* cfg80211: advertise extended capabilities to userspaceJohannes Berg2013-02-151-0/+9
| | | | | | | | | | | In many cases, userspace may need to know which of the 802.11 extended capabilities ("Extended Capabilities element") are implemented in the driver or device, to include them e.g. in beacons, assoc request/response or other frames. Add a new nl80211 attribute to hold the extended capabilities bitmap for this. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new NL80211_CMD_RADAR_DETECT, which starts the Channel Availability Check (CAC). This command will also notify the usermode about events (CAC finished, CAC aborted, radar detected, NOP finished).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While technically the TSF isn't an IE, it can be necessary to distinguish between the TSF from a beacon and a probe response, in particular in order to know the next DTIM TBTT, as not all APs are spec compliant wrt. TSF==0 being a DTIM TBTT and thus the DTIM count needs to be taken into account as well. To allow this, move the TSF into the IE struct so it can be known whence it came.

* | cfg80211: track hidden SSID networks properlyJohannes Berg2013-02-112-54/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, cfg80211 will copy beacon IEs from a previously received hidden SSID beacon to a probe response entry, if that entry is created after the beacon entry. However, if it is the other way around, or if the beacon is updated, such changes aren't propagated. Fix this by tracking the relation between the probe response and beacon BSS structs in this case. In case drivers have private data stored in a BSS struct and need access to such data from a beacon entry, cfg80211 now provides the hidden_beacon_bss pointer from the probe response entry to the beacon entry.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to find a hidden SSID, the lookup function is done wrong; the code is trying to combine the two lookups into one, and as a consequence doesn't always find the entry at all. To understand this, consider a case where multiple BSS entries with the same channel and BSSID exist but have different SSID length. Then comparing against the probe response SSID length is bound to cause problems since the hidden one might be either zeroed out or zero-length. To fix this we need to do two lookups for the two ways to hide SSIDs. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per email discussion Jouni Malinen pointed out that: "P2P message exchanges can be executed on the current operating channel of any operation (both P2P and non-P2P station). These can be on 5 GHz and even on 60 GHz (so yes, you _can_ do GO Negotiation on 60 GHz). As an example, it would be possible to receive a GO Negotiation Request frame on a 5 GHz only radio and then to complete GO Negotiation on that band. This can happen both when connected to a P2P group (through client discoverability mechanism) and when connected to a legacy AP (assuming the station receive Probe Request frame from full scan in the beginning of P2P device discovery)." This means that P2P messages can be sent over different radio devices. However, these should use the same P2P device address so it should be able to provision this from user-space. This patch adds a parameter for this to struct vif_params which should only be used during creation of the P2P device interface.

Consider this change: - reset_regdomains(true); - cfg80211_regdomain = cfg80211_world_regdom; + reset_regdomains(true, cfg80211_world_regdom); This looks innocent enough, until you realise that the called function (reset_regdomains) also resets the cfg80211_world_regdom pointer, so that the old version of the code would use the new object it pointed to and the new version of the code uses the old object.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Today, stations are added already associated. That is inefficient if, for example, the driver has no room for stations any more because then the station will go through the entire auth/assoc handshake, only to be kicked out afterwards. To address this a bit better, at least with drivers using the new station state callback, allow hostapd to add stations in unauthenticated mode, just after receiving the AUTH frame, before even replying. Thus if there's no more space at that point, it can send a negative auth frame back. It still needs to handle later state transition errors though, of course.

* | cfg80211: do not process beacon hints if one is already queuedLuis R. Rodriguez2013-01-031-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regulatory beacon hints are used to help with world roaming and as it is right now we learn from a beacon hint processed on one wiphy to all other wiphys. The processing of beacon hints however is scheduled and if we have a lot of interfaces we may hit the case that we'll queue a the same beacon hint many times until its processed. To avoid this do a lookup on the queued up beacon hints prior to adding a new beacon hint. If the beacon hint is removed from the pending reg beacon hint list then it would be processed and we'd ensure all wiphys would have learned from it, if its on the pending reg beacon list we'd now find it prior to it being processed.
