* Use per-interface type driver key_mgmt capabilities when possibleVeerendranath Jakkam2020-05-121-1/+5
| | | | | | | | | | | Use key_mgmt_iftype instead of key_mgmt when the specific interface type is known by the context of the operation. Use per interface type AKM capabilities in capa.key_mgmt_iftype array based on the wpa_supplicant context instead of using capa.key_mgmt to determine the driver AKM capability.

* WPS: Convert WPA/TKIP-only to WPA+WPA2 mixed mode credentialJouni Malinen2020-04-171-2/+2
| | | | | | | | | | | This case of accepting WPA/TKIP-only credential based on internal registrar request to configure an AP to use TKIP was still remaining while all the WPS cases were supposed to enable mixed mode automatically. This is bit of a corner case since this is based on explicit local request to configure TKIP, but anyway, convert this one as well to allow WPA2/CCMP to be used.

* Allow TKIP support to be removed from buildDisha Das2020-04-171-0/+5
| | | | | | | | | Add a build flag CONFIG_NO_TKIP=y to remove all TKIP functionality from hostapd and wpa_supplicant builds. This disables use of TKIP as both the pairwise and group cipher. The end result does not interoperate with a WPA(v1)-only device or WPA+WPA2 mixed modes. Signed-off-by: Disha Das <dishad@codeaurora.org>
* WPS: Do not set auth_alg=OPEN for PSK+SAE caseJouni Malinen2020-03-101-0/+1
| | | | | | | | | | | When wps_cred_add_sae=1 is used, WPS_AUTH_WPA2PSK credential gets converted to enabling both PSK and SAE AKMs. However, this case was still hardcoded auth_alg=OPEN which is not really correct for SAE. While the SME-in-wpa_supplicant case can handle that, the SME-in-driver case might not. Remove the unnecessary auth_alg=OPEN configuration to get the normal PSK+SAE configuration enabled for the network profile. Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
* WPS: Ignore other APs if PBC is used with a specific BSSIDJouni Malinen2020-02-241-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | While the WSC specification requires the Enrollee to stop PBC provisioning if the scan sees multiple APs in active PBC mode, this is problematic due to some deployed devices continuing to advertise PBC mode for extended duration (or even permanently). Such an environment will still need to prevent wildcard AP selection with PBC since an incorrect device could be selected. However, if the Enrollee device has been explicitly requested to connect to a specific AP based on its BSSID, the other APs in scan results can be ignored without affecting which AP would be selected (only the one matching the specified BSSID is acceptable). Start filtering scan results for PBC session overlap check based on the locally specified constraint on the BSSID, if one is set. This allows PBC to be used with "WPS_PBC <BSSID>" command in environment where another AP device is claiming to be in active PBC mode while "WPS_PBC" command will still continue to reject provisioning since the correct AP cannot be selected. This will also cover the P2P cases where P2P_CONNECT is used to start or authorize GO Negotiation and joining-a-GO with a specific P2P GO Interface Address (BSSID).

* P2P: Add support for EDMG channelsAhmad Masri2019-12-191-0/+10
| | | | | | | | | | | | | | | | | | | | | | This allows a P2P connection over P802.11ay EDMG channels to achieve the highest link speed that the standard allows for channel bonding (CB) up to CB4. Let each P2P peer add its EDMG channels to the Supported Channels IE advertised in P2P GO negotiation. Give EDMG channels priority when peers negotiate for operating channel. User may add 'edmg' parameter to p2p_connect, p2p_add_group, and p2p_invite commands to prefer an EDMG channel for the P2P link. User may also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer EDMG. When EDMG is used, P2P will try to find the highest channel bonding supported channel that matches the frequency parameter, if the devices do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz channel.

* wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPSDavina Lu2019-02-181-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* P2P: Add a separate pointer to the P2P Device instanceLior David2016-02-271-6/+6
| | | | | | | | | | | | | | | In many places in the code there was a reference to wpa_s->parent to get from group interface to p2p_dev interface. 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: Basic support for PBSS/PCPLior David2016-02-081-0/+8
| | | | | | | | | | | | | | | | | | | | | PBSS (Personal Basic Service Set) is a new BSS type for DMG networks. It is similar to infrastructure BSS, having an AP-like entity called PCP (PBSS Control Point), but it has few differences. PBSS support is mandatory for IEEE 802.11ad devices. Add a new "pbss" argument to network block. The argument is used in the following scenarios: 1. When network has mode=2 (AP), when pbss flag is set will start as a PCP instead of an AP. 2. When network has mode=0 (station), when pbss flag is set will connect to PCP instead of AP. The function wpa_scan_res_match() was modified to match BSS according to the pbss flag in the network block (wpa_ssid structure). When pbss flag is set it will match only PCPs, and when it is clear it will match only APs. Signed-off-by: Lior David <qca_liord@qca.qualcomm.com>
* WPS: Reconnect for a failed data connection when STA_AUTOCONNECT is 0Sunil Dutt2015-11-171-0/+7
| | | | | | | | | | | | | | | | | If "STA_AUTOCONNECT 0" has been used to disable automatic connection on disconnection event and the driver indicates a failure for the data connection after successful WPS handshake, it is possible to hit a case where wpa_s->disconnected is set to 1 and further attempts to connect shall stop. While "STA_AUTOCONNECT 0" is used to disable automatic reconnection attempts in general, this specific WPS case can benefit from trying again even with that configuration for a short period of time. Extend the wpa_supplicant re-enable-networks-after-WPS 10 second timeout to apply for ignoring disabled STA_AUTOCONNECT immediately after a WPS provisioning step.

* P2P: Fix PBC overlap detectionAvraham Stern2015-06-191-29/+28
| | | | | | | | | | | | | | 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>

* WPS: Enforce five second minimum time before AP iterationHu Wang2015-04-241-3/+18
| | | | | | | | | | | | | | 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: Remove unused Credential AP Channel processingJouni Malinen2014-02-041-19/+9
| | | | | | | | | | | | | | | | 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>
