* | cfg80211: average ack rssi support for data framesBalaji Pothunoori2018-05-071-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Average ack rssi will be given to userspace via NL80211 interface if firmware is capable. Userspace tool ‘iw’ can process this information and give the output as one of the fields in ‘iw dev wlanX station dump’. Example output : localhost ~ #iw dev wlan-5000mhz station dump Station 34:f3:9a:aa:3b:29 (on wlan-5000mhz) inactive time: 5370 ms rx bytes: 85321 rx packets: 576 tx bytes: 14225 tx packets: 71 tx retries: 0 tx failed: 2 beacon loss: 0 rx drop misc: 0 signal: -54 dBm signal avg: -53 dBm tx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2 rx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2 avg ack signal: -56 dBm authorized: yes authenticated: yes associated: yes preamble: short WMM/WME: yes MFP: no TDLS peer: no DTIM period: 2 beacon interval:100 short preamble: yes short slot time:yes connected time: 203 seconds Main use case is to measure the signal strength of a connected station to AP. Data packet transmit rates and bandwidth used by station can vary a lot even if the station is at fixed location, especially if the rates used are multi stream(2stream, 3stream) rates with different bandwidth(20/40/80 Mhz). These multi stream rates are sensitive and station can use different transmit power for each of the rate and bandwidth combinations. RSSI measured from these RX packets on AP will be not stable and can vary a lot with in a short time. Whereas 802.11 ack frames from station are sent relatively at a constant rate (6/12/24 Mbps) with constant bandwidth(20 Mhz). So average rssi of the ack packets is good and more accurate.

* nl80211: Implement TX of control port framesDenis Kenzior2018-03-291-0/+3
| | | | | | | | | | | | | | | | This commit implements the TX side of NL80211_CMD_CONTROL_PORT_FRAME. Userspace provides the raw EAPoL frame using NL80211_ATTR_FRAME. Userspace should also provide the destination address and the protocol type to use when sending the frame. This is used to implement TX of Pre-authentication frames. If CONTROL_PORT_ETHERTYPE_NO_ENCRYPT is specified, then the driver will be asked not to encrypt the outgoing frame. A new EXT_FEATURE flag is introduced so that nl80211 code can check whether a given wiphy has capability to pass EAPoL frames over nl80211.

* cfg80211/nl80211: Optional authentication offload to userspaceSrinivas Dasari2018-01-311-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | This interface allows the host driver to offload the authentication to user space. This is exclusively defined for host drivers that do not define separate commands for authentication and association, but rely on userspace SME (e.g., in wpa_supplicant for the ~WPA_DRIVER_FLAGS_SME case) for the authentication to happen. This can be used to implement SAE without full implementation in the kernel/firmware while still being able to use NL80211_CMD_CONNECT with driver-based BSS selection. Host driver sends NL80211_CMD_EXTERNAL_AUTH event to start/abort authentication to the port on which connect is triggered and status of authentication is further indicated by user space to host driver through the same command response interface. User space entities advertise this capability through the NL80211_ATTR_EXTERNAL_AUTH_SUPP flag in the NL80211_CMD_CONNECT request. Host drivers shall look at this capability to offload the authentication.

* cfg80211/nl80211: add a port authorized eventAvraham Stern2017-10-021-11/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an event that indicates that a connection is authorized (i.e. the 4 way handshake was performed by the driver). This event should be sent by the driver after sending a connect/roamed event. This is useful for networks that require 802.1X authentication. In cases that the driver supports 4 way handshake offload, but the 802.1X authentication is managed by user space, the driver needs to inform user space right after the 802.11 association was completed so user space can initialize its 802.1X state machine etc. However, it is also possible that the AP will choose to skip the 802.1X authentication (e.g. when PMKSA caching is used) and proceed with the 4 way handshake immediately. In this case the driver needs to inform user space that 802.1X authentication is no longer required (e.g. to prevent user space from disconnecting since it did not get any EAPOLs from the AP). This is also useful for roaming, in which case it is possible that the driver used the Fast Transition protocol so 802.1X is not required. Since there will now be a dedicated notification indicating that the connection is authorized, the authorized flag can be removed from the roamed event. Drivers can send the new port authorized event right after sending the roamed event to indicate the new AP is already authorized. This therefore reserves the old PORT_AUTHORIZED attribute.

The driver / firmware will decide whether to use it or not. Include a feature bit to advertise support for NL80211_MFP_OPTIONAL.

* nl80211: Don't verify owner_nlportid on NAN commandsAndrei Otcheretianski2017-06-301-5/+4
| | | | | | | | | | | | | | | | | | | If NAN interface is created with NL80211_ATTR_SOCKET_OWNER, the socket that is used to create the interface is used for all NAN operations and reporting NAN events. However, it turns out that sending commands and receiving events on the same socket is not possible in a completely race-free way: If the socket buffer is overflowed by the events, the command response will not be sent. In that case the caller will block forever on recv. Using non-blocking socket for commands is more complicated and still the command response or ack may not be received. So, keep unicasting NAN events to the interface creator, but allow using a different socket for commands.

* nl80211: add authorized flag to ROAM eventAvraham Stern2017-06-131-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | Drivers that initiate roaming while being connected to a network that uses 802.1X authentication need to inform user space if 802.1X authentication is further required after roaming. For example, when using the Fast transition protocol, roaming within the mobility domain does not require new 802.1X authentication, but roaming to another mobility domain does. In addition, some drivers may not support 802.1X authentication (so it has to be done in user space), while other drivers do. Add a flag to the roaming notification to indicate if user space is required to do 802.1X authentication after the roaming or not. This flag will only be used for networks that use 802.1X authentication. For networks that do not use 802.1X authentication it is assumed that no further action is required from user space after the roaming notification.

| | | | | | | | | | | | | | | | | | | | | | | | | | DFS requirement for ETSI domain (section 4.7.1.4 in ETSI EN 301 893 V1.8.1) is the only one which explicitly states that once DFS channel is marked as available afer the CAC, this channel will remain in available state even moving to a different operating channel. But the same is not explicitly stated in FCC DFS requirement. Also, Pre-CAC requriements are not explicitly mentioned in FCC requirement. Current implementation in keeping DFS channel in available state is same as described in ETSI domain. For non-ETSI DFS domain, this patch gives a grace period of 2 seconds since the completion of successful CAC before moving the channel's DFS state to 'usable' from 'available' state. The same grace period is checked against the channel's dfs_state_entered timestamp while deciding if a DFS channel is available for operation. There is a new radar event, NL80211_RADAR_PRE_CAC_EXPIRED, reported when DFS channel is moved from available to usable state after the grace period. Also make sure the DFS channel state is reset to usable once the beaconing operation on that channel is brought down (like stop_ap, leave_ibss and leave_mesh) in non-ETSI domain.

| | | | | | | | | | | | | | | | | | | | | | | Change the SET CQM command's RSSI threshold attribute to accept any number of thresholds as a sorted array. The API should be backwards compatible so that if one s32 threshold value is passed, the old mechanism is enabled. The netlink event generated is the same in both cases. cfg80211 handles an arbitrary number of RSSI thresholds but drivers have to provide a method (set_cqm_rssi_range_config) that configures a range set by a high and a low value. Drivers have to call back when the RSSI goes out of that range and there's no additional event for each time the range is reconfigured as there was with the current one-threshold API. This method doesn't have a hysteresis parameter because there's no benefit to the cfg80211 code from having the hysteresis be handled by hardware/driver in terms of the number of wakeups. At the same time it would likely be less consistent between drivers if offloaded or done in the drivers.

| | | | | | | | | | | | | | | | | | Update the drivers to pass the RSSI level as a cfg80211_cqm_rssi_notify parameter and pass this value to userspace in a new nl80211 attribute. This helps both userspace and also helps in the implementation of the multiple RSSI thresholds CQM mechanism. Note for marvell/mwifiex I pass 0 for the RSSI value because the new RSSI value is not available to the driver at the time of the cfg80211_cqm_rssi_notify call, but the driver queries the new value immediately after that, so it is actually available just a moment later if we wanted to defer caling cfg80211_cqm_rssi_notify until that moment. Without this, the new cfg80211 code (patch 3) will call .get_station which will send a duplicate HostCmd_CMD_RSSI_INFO command to the hardware.

* | cfg80211: Add support for randomizing TA of Public Action framesvamsi krishna2017-01-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to use a random local address (Address 2 = TA in transmit and the same address in receive functionality) for Public Action frames in order to improve privacy of WLAN clients. Applications fill the random transmit address in the frame buffer in the NL80211_CMD_FRAME command. This can be used only with the drivers that indicate support for random local address by setting the new NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA and/or NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA_CONNECTED in ext_features. The driver needs to configure receive behavior to accept frames to the specified random address during the time the frame exchange is pending and such frames need to be acknowledged similarly to frames sent to the local permanent address when this random address functionality is not used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disconnect or deauthenticate when the owning socket is closed if this flag is supplied to CMD_CONNECT or CMD_ASSOCIATE. This may be used to ensure userspace daemon doesn't leave an unmanaged connection behind. In some situations it would be possible to account for that, to some degree, in the deamon restart code or in the up/down scripts without the use of this attribute. But there will be systems where the daemon can go away for varying periods without a warning due to local resource management.

* nl80211: Use different attrs for BSSID and random MAC addr in scan reqVamsi Krishna2016-12-091-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned and the random MAC address to be used when privacy is enabled. When both the features are enabled, both the BSSID and the local MAC address were getting same value causing Probe Request frames to go with unintended DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID attribute to set the specific BSSID (which was the more recent addition in cfg80211) for a scan. Backwards compatibility with old userspace software is maintained to some extent by allowing NL80211_ATTR_MAC to be used to set the specific BSSID when scanning without enabling random MAC address use. Scanning with random source MAC address was introduced by commit ad2b26abc157 ("cfg80211: allow drivers to support random MAC addresses for scan") and the issue was introduced with the addition of the second user for the same attribute in commit 818965d39177 ("cfg80211: Allow a scan request for a specific BSSID").

* cfg80211: Add support to update connection parametersvamsi krishna2016-10-271-0/+8
| | | | | | | | | | | | | | | | | | Add functionality to update the connection parameters when in connected state, so that driver/firmware uses the updated parameters for subsequent roaming. This is for drivers that support internal BSS selection and roaming. The new command does not change the current association state, i.e., it can be used to update IE contents for future (re)associations without causing an immediate disassociation or reassociation with the current BSS. This commit implements the required functionality for updating IEs for (Re)Association Request frame only. Other parameters can be added in future when required.

* cfg80211: configure multicast to unicast for AP interfacesMichael Braun2016-10-271-0/+21
| | | | | | | | | | | | | | | | | | | | | | Add the ability to configure if an AP (and associated VLANs) will do multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames (possibly within 802.1Q). If enabled, such frames are to be sent to each station separately, with the DA replaced by their own MAC address rather than the group address. Note that this may break certain expectations of the receiver, such as the ability to drop unicast IP packets received within multicast L2 frames, or the ability to not send ICMP destination unreachable messages for packets received in L2 multicast (which is required, but the receiver can't tell the difference if this new option is enabled.) This also doesn't implement the 802.11 DMS (directed multicast service).

FILS does not need the special rules for the Authentication transaction number and Status code fields, but it does need to add non-IE fields. The previously used NL80211_ATTR_SAE_DATA can be reused for this to avoid having to duplicate that implementation. Rename that attribute to more generic NL80211_ATTR_AUTH_DATA (with backwards compatibility define for NL80211_SAE_DATA). Also document the special rules related to the Authentication transaction number and Status code fiels.

* cfg80211: support virtual interfaces with different beacon intervalsPurushottam Kushwaha2016-10-131-2/+6
| | | | | | | | | | | | | | | | | | | | This commit provides a mechanism for the host drivers to advertise the support for different beacon intervals among the respective interface combinations in a group, through NL80211_IFACE_COMB_BI_MIN_GCD (u32). This value will be compared against GCD of all beaconing interfaces of matching combinations. If the driver doesn't advertise this value, the old behaviour where all beacon intervals must be identical is retained. If it is specified, then any beacon interval for an interface in the interface combination as well as the GCD of all active beacon intervals in the combination must be greater or equal to this value.
