| * cfg80211: add support to probe unexercised mesh linkRajkumar Manoharan2019-04-261-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding support to allow mesh HWMP to measure link metrics on unexercised direct mesh path by sending some data frames to other mesh points which are not currently selected as a primary traffic path but only 1 hop away. The absence of the primary path to the chosen node makes it necessary to apply some form of marking on a chosen packet stream so that the packets can be properly steered to the selected node for testing, and not by the regular mesh path lookup.

| * cfg80211/nl80211: Offload OWE processing to user space in AP modeSunil Dutt2019-04-081-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This interface allows the host driver to offload OWE processing to user space. This intends to support OWE (Opportunistic Wireless Encryption) AKM by the drivers that implement SME but rely on the user space for the cryptographic/OWE processing in AP mode. Such drivers are not capable of processing/deriving the DH IE. A new NL80211 command - NL80211_CMD_UPDATE_OWE_INFO is introduced to send the request/event between the host driver and user space. Driver shall provide the OWE info (MAC address and DH IE) of the peer to user space for cryptographic processing of the DH IE through the event. Accordingly, the user space shall update the OWE info/DH IE to the driver. Following is the sequence in AP mode for OWE authentication. Driver passes the OWE info obtained from the peer in the Association Request to the user space through the event cfg80211_update_owe_info_event. User space shall process the OWE info received and generate new OWE info. This OWE info is passed to the driver through NL80211_CMD_UPDATE_OWE_INFO request. Driver eventually uses this OWE info to send the Association Response to the peer. This OWE info in the command interface carries the IEs that include PMKID of the peer if the PMKSA is still valid or an updated DH IE for generating a new PMKSA with the peer.

| * nl80211/cfg80211: Specify band specific min RSSI thresholds with sched scanvamsi krishna2019-04-081-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds the support to specify the RSSI thresholds per band for each match set. This enhances the current behavior which specifies a single rssi_threshold across all the bands by introducing the rssi_threshold_per_band. These per band rssi thresholds are referred through NL80211_BAND_* (enum nl80211_band) variables as attribute types. Such attributes/values per each band are nested through NL80211_ATTR_SCHED_SCAN_MIN_RSSI. These band specific rssi thresholds shall take precedence over the current rssi_thold per match set. Drivers indicate this support through %NL80211_EXT_FEATURE_SCHED_SCAN_BAND_SPECIFIC_RSSI_THOLD. These per band rssi attributes/values does not specify "default RSSI filter" as done by NL80211_SCHED_SCAN_MATCH_ATTR_RSSI to stay backward compatible. That said, these per band rssi values have to be specified for the corresponding matchset.

In practice, this adds (Re)Association Request frame information element reporting to mac80211 drivers for the cases where user space SME is used. This provides more information for user space to figure out which capabilities were negotiated for the association. For example, this can be used to determine whether HT, VHT, or HE is used.

* cfg80211: Authentication offload to user space in AP modeSrinivas Dasari2019-01-251-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 40cbfa90218b ("cfg80211/nl80211: Optional authentication offload to userspace")' introduced authentication offload to user space by the host drivers in station mode. This commit extends the same for the AP mode too. Extend NL80211_ATTR_EXTERNAL_AUTH_SUPPORT to also claim the support of external authentication from the user space in AP mode. A new flag parameter is introduced in cfg80211_ap_settings to intend the same while "start ap". Host driver to use NL80211_CMD_FRAME interface to transmit and receive the authentication frames to / from the user space. Host driver to indicate the flag NL80211_RXMGMT_FLAG_EXTERNAL_AUTH while sending the authentication frame to the user space. This intends to the user space that the driver wishes it to process the authentication frame for certain protocols, though it had initially advertised the support for SME functionality. User space shall accordingly do the authentication and indicate its final status through the command NL80211_CMD_EXTERNAL_AUTH. Allow the command even if userspace doesn't include the attribute NL80211_ATTR_SSID for AP interface. Host driver shall continue with the association sequence and indicate the STA connection status through cfg80211_new_sta. To facilitate the host drivers in AP mode for matching the pmkid by the stations during the association, NL80211_CMD_EXTERNAL_AUTH is also enhanced to include the pmkid to drivers after the authentication. This pmkid can also be used in the STA mode to include in the association request. Also modify nl80211_external_auth to not mandate SSID in AP mode.

* cfg80211: Allow drivers to advertise supported AKM suitesVeerendranath Jakkam2019-01-251-0/+5
| | | | | | | | | | | | | | | There was no such capability advertisement from the driver and thus the current user space has to assume the driver to support all the AKMs. While that may be the case with some drivers (e.g., mac80211-based ones), there are cfg80211-based drivers that implement SME and have constraints on which AKMs can be supported (e.g., such drivers may need an update to support SAE AKM using NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to advertise the exact set of supported AKMs so that user space tools can determine what network profile options should be allowed to be configured.

* cfg80211: add peer measurement with FTM initiator APIJohannes Berg2018-11-091-0/+263
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new "peer measurement" API, that can be used to measure certain things related to a peer. Right now, only implement FTM (flight time measurement) over it, but the idea is that it'll be extensible to also support measuring the necessary things to calculate e.g. angle-of-arrival for WiGig. The API is structured to have a generic list of peers and channels to measure with/on, and then for each of those a set of measurements (again, only FTM right now) to perform. Results are sent to the requesting socket, including a final complete message. Closing the controlling netlink socket will abort a running measurement. v3: - add a bit to report "final" for partial results - remove list keeping etc. and just unicast out the results to the requester (big code reduction ...) - also send complete message unicast, and as a result remove the multicast group - separate out struct cfg80211_pmsr_ftm_request_peer from struct cfg80211_pmsr_request_peer - document timeout == 0 if no timeout - disallow setting timeout nl80211 attribute to 0, must not include attribute for no timeout - make MAC address randomization optional - change num bursts exponent default to 0 (1 burst, rather rather than the old default of 15==don't care) v4: - clarify NL80211_ATTR_TIMEOUT documentation v5: - remove unnecessary nl80211 multicast/family changes - remove partial results bit/flag, final is sufficient - add max_bursts_exponent, max_ftms_per_burst to capability - rename "frames per burst" -> "FTMs per burst" v6: - rename cfg80211_pmsr_free_wdev() to cfg80211_pmsr_wdev_down() and call it in leave, so the device can't go down with any pending measurements v7: - wording fixes (Lior) - fix ftm.max_bursts_exponent to allow having the limit of 0 (Lior) v8: - copyright statements - minor coding style fixes - fix error path leak Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* nl80211: Add per peer statistics to compute FCS error rateAnkita Bajaj2018-10-121-0/+7
| | | | | | | | | | | | | | | | | | | | Add support for drivers to report the total number of MPDUs received and the number of MPDUs received with an FCS error from a specific peer. These counters will be incremented only when the TA of the frame matches the MAC address of the peer irrespective of FCS error. It should be noted that the TA field in the frame might be corrupted when there is an FCS error and TA matching logic would fail in such cases. Hence, FCS error counter might not be fully accurate, but it can provide help in detecting bad RX links in significant number of cases. This FCS error counter without full accuracy can be used, e.g., to trigger a kick-out of a connected client with a bad link in AP mode to force such a client to roam to another AP.

| | * cfg80211: make wmm_rule part of the reg_rule structureStanislaw Gruszka2018-08-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make wmm_rule be part of the reg_rule structure. This simplifies the code a lot at the cost of having bigger memory usage. However in most cases we have only few reg_rule's and when we do have many like in iwlwifi we do not save memory as it allocates a separate wmm_rule for each channel anyway. This also fixes a bug reported in various places where somewhere the pointers were corrupted and we ended up doing a null-dereference.

| * nl80211/mac80211: allow non-linear skb in rx_control_portDenis Kenzior2018-07-061-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of cfg80211_rx_control_port assumed that the caller could provide a contiguous region of memory for the control port frame to be sent up to userspace. Unfortunately, many drivers produce non-linear skbs, especially for data frames. This resulted in userspace getting notified of control port frames with correct metadata (from address, port, etc) yet garbage / nonsense contents, resulting in bad handshakes, disconnections, etc. mac80211 linearizes skbs containing management frames. But it didn't seem worthwhile to do this for control port frames. Thus the signature of cfg80211_rx_control_port was changed to take the skb directly. nl80211 then takes care of obtaining control port frame data directly from the (linear | non-linear) skb. The caller is still responsible for freeing the skb, cfg80211_rx_control_port does not take ownership of it.
