P2P: Reject group formation on WPS provisioning failure There is no need to wait for the 15 second group formation timeout to clear the state if WPS failure is detected during P2P group formation. Allow the WPS exchange steps (WSC_NACK and EAP-Failure) to be completed and remove the group to get rid of the extra wait. Signed-hostap: Jouni Malinen <j@w1.fi>

WPS: Add new mechanism for NFC config method using password token Instead of requiring low-level access to an NFC device and synchronous operations, the new WPS_NFC_TOKEN and WPS_NFC ctrl_iface commands can be used to build a NFC password token and initiate WPS protocol run using that token (or pre-configured values) as separate commands. The WPS_NFC_TOKEN output can be written to a NFC tag using an external program, i.e., wpa_supplicant does not need to have low-level code for NFC operations for this.

WPS: Enforce five second minimum time before AP iteration Previously, wpa_supplicant was using number of scan iterations (WPS_PIN_SCAN_IGNORE_SEL_REG = 3) to give some time for finding a WPS AP with Selected Registrar TRUE before starting to iterate through all WPS APs. While this works fine in most cases, some drivers may return the initial three scan results so quickly that the total amount of time is only couple of seconds in case none of the APs are initially advertising Selected Registrar TRUE. To give some more time for APs (WPS Registrars) to become ready, add an additional constraint on the iteration based on time (WPS_PIN_TIME_IGNORE_SEL_REG = 5 seconds).

WPS: Pick WPS AP based on latest received WPS IE wpa_supplicant used the WPS IE from a Probe Response frame, if one was received, even if there might have been a more recent Beacon frame with an updated WPS IE. This could result in using stale information about active WPS registrar, e.g., when operating on the 6 GHz band. Prefer WPS IE from a Beacon frame over the default selection of Probe Response frame (if one has been received) in cases where the Beacon frame is received more recently than the Probe Response frame and active WPS Registrar information is being checked. Skip this for the case where UUID-E is needed since that is not available in the Beacon frame. Signed-off-by: Sai Pratyusha Magam <quic_smagam@quicinc.com>

Use normal scan before sched_scan if that can speed up connection When normal scan can speed up operations, use that for the first three scan runs before starting the sched_scan to allow user space sleep more. We do this only if the normal scan has functionality that is suitable for this or if the sched_scan does not have better support for multiple SSIDs.

WPS: Pick WPS AP based on latest received WPS IE wpa_supplicant used the WPS IE from a Probe Response frame, if one was received, even if there might have been a more recent Beacon frame with an updated WPS IE. This could result in using stale information about active WPS registrar, e.g., when operating on the 6 GHz band. Prefer WPS IE from a Beacon frame over the default selection of Probe Response frame (if one has been received) in cases where the Beacon frame is received more recently than the Probe Response frame and active WPS Registrar information is being checked. Skip this for the case where UUID-E is needed since that is not available in the Beacon frame. Signed-off-by: Sai Pratyusha Magam <quic_smagam@quicinc.com>

WPS: Add a workaround for TKIP/CCMP mixed mode credentials Many deployed APs do not handle negotiation of security parameters well when both TKIP and CCMP (or both WPA and WPA2) are enabled. The most common end result seems to be ending up with the least secure option.. As a workaround, check whether the AP advertises WPA2/CCMP in Beacon frames and add those options for the credential if needed. This allows the client to select the most secure configuration regardless of how broken the AP's WPS implementation is as far as auth/encr type negotiation is concerned.

These places can break if P2P_DEVICE interface would need to be used with the primary interface as the group interface, since the parent of the primary interface points to itself and not the p2p_dev interface. Fix this by adding a separate "p2pdev" pointer to wpa_supplicant, it will be the same as parent pointer in most cases but whenever the primary interface is used as a group interface, change it to point to the correct p2p_dev interface.

wpa_supplicant: Track consecutive connection failures Within wpas_connection_failed(), the 'count' value of wpa_blacklist is erroneously used as a tally of the number times the device has failed to associate to a given BSSID without making a successful connection. This is not accurate because there are a variety of ways a BSS can be added to the blacklist beyond failed association such as interference or deauthentication. This 'count' is lost whenever the blacklist is cleared, so the wpa_supplicant stores an additional value 'extra_blacklist_count' which helps persist the 'count' through clears. These count values are used to determine how long to wait to rescan after a failed connection attempt. While this logic was already slightly wrong, it would have been completely broken by the upcoming change which adds time-based blacklisting functionality. With the upcoming change, 'count' values are not cleared on association, and thus do not necessarily even approximate the "consecutive connection failures" which they were being used for. This change seeks to remove this unnecessary overloading of the blacklist 'count' by directly tracking consecutive connection failures within the wpa_supplicant struct, independent of the blacklist. This new 'consecutive_conn_failures' is iterated with every connection failure and cleared when any successful connection is made. This change also removes the now unused 'extra_blacklist_count' value. Signed-off-by: Kevin Lund <kglund@google.com> Signed-off-by: Brian Norris <briannorris@chromium.org>

wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPS The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a backhaul STA through WPS. To enable this, the backhaul STA needs to add a Multi-AP IE to the WFA vendor extension element in the WSC M1 message that indicates it supports the Multi-AP backhaul STA role. The Registrar (if it support Multi-AP onboarding) will respond to that with a WSC M8 message that also contains the Multi-AP IE, and that contains the credentials for the backhaul SSID (which may be different from the SSID on which WPS is performed). Introduce a new parameter to wpas_wps_start_pbc() and allow it to be set via control interface's new multi_ap=1 parameter of WPS_PBC call. multi_ap_backhaul_sta is set to 1 in the automatically created SSID. Thus, if the AP does not support Multi-AP, association will fail and WPS will be terminated. Only wps_pbc is supported. This commit adds the multi_ap argument only to the control socket interface, not to the D-Bus interface. Since WPS associates with the fronthaul BSS instead of the backhaul BSS, we should not drop association if the AP announces fronthaul-only BSS. Still, we should only do that in the specific case of WPS. Therefore, add a check to multi_ap_process_assoc_resp() to allow association with a fronthaul-only BSS if and only if key_mgmt contains WPS.

wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPS The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a backhaul STA through WPS. To enable this, the backhaul STA needs to add a Multi-AP IE to the WFA vendor extension element in the WSC M1 message that indicates it supports the Multi-AP backhaul STA role. The Registrar (if it support Multi-AP onboarding) will respond to that with a WSC M8 message that also contains the Multi-AP IE, and that contains the credentials for the backhaul SSID (which may be different from the SSID on which WPS is performed). Introduce a new parameter to wpas_wps_start_pbc() and allow it to be set via control interface's new multi_ap=1 parameter of WPS_PBC call. multi_ap_backhaul_sta is set to 1 in the automatically created SSID. Thus, if the AP does not support Multi-AP, association will fail and WPS will be terminated. Only wps_pbc is supported. This commit adds the multi_ap argument only to the control socket interface, not to the D-Bus interface. Since WPS associates with the fronthaul BSS instead of the backhaul BSS, we should not drop association if the AP announces fronthaul-only BSS. Still, we should only do that in the specific case of WPS. Therefore, add a check to multi_ap_process_assoc_resp() to allow association with a fronthaul-only BSS if and only if key_mgmt contains WPS.

WPS: Enforce five second minimum time before AP iteration Previously, wpa_supplicant was using number of scan iterations (WPS_PIN_SCAN_IGNORE_SEL_REG = 3) to give some time for finding a WPS AP with Selected Registrar TRUE before starting to iterate through all WPS APs. While this works fine in most cases, some drivers may return the initial three scan results so quickly that the total amount of time is only couple of seconds in case none of the APs are initially advertising Selected Registrar TRUE. To give some more time for APs (WPS Registrars) to become ready, add an additional constraint on the iteration based on time (WPS_PIN_TIME_IGNORE_SEL_REG = 5 seconds).

In addition, add UUID-R into SetSelectedRegistrar action to make it potentially easier for an AP to figure out which ER sent the action should there be multiple ERs using the same IP address.

WPS: Remove unused Credential AP Channel processing Commit bd3a3737672aaf6eb50dba2b8caa3941c8df42e9 added a mechanism to use AP Channel attribute from within a Credential attribute to optimize scans. However, this design is not actually used with the WPS NFC use cases. With configuration token, the AP Channel attribute is in the same container with the Credential attribute (and that was also handled in the previous implementation). With connection handover, AP Channel information is outside the Credential attribute as well. Simplify implementation by removing the AP Channel within Credential case. This allows wpas_wps_use_cred() to get the AP Channel from the container instead of having to find this during credential iteration. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

WPS NFC: Remove NFC_RX_HANDOVER_SEL The newer NFC_REPORT_HANDOVER command is more general version that handles the cases where NFC_RX_HANDOVER_SEL could potentially have been used. In addition, with the new WPS NFC design, it is important to receive the handover request message that was used in the handover in addition to the select message, so the NFC_RX_HANDOVER_SEL command on its own would not be sufficient for this.

WPS: Add new mechanism for NFC config method using password token Instead of requiring low-level access to an NFC device and synchronous operations, the new WPS_NFC_TOKEN and WPS_NFC ctrl_iface commands can be used to build a NFC password token and initiate WPS protocol run using that token (or pre-configured values) as separate commands. The WPS_NFC_TOKEN output can be written to a NFC tag using an external program, i.e., wpa_supplicant does not need to have low-level code for NFC operations for this.

P2P: Fix PBC overlap detection PBC overlap detection searches for another BSS with active PBC in the BSS table. However, when a separate P2P interface is used, scan results without P2P IE are not saved in the BSS table, so non-P2P BSS's with active PBC will not be detected. Fix this by iterating only the WPS AP array instead of the BSS table. This is also more efficient since only WPS APs may have active PBC. This also fixes hwsim test "grpform_pbc_overlap" when a dedicated P2P Device is used. Signed-off-by: Avraham Stern <avraham.stern@intel.com>
