* RSN: Verify RSNXE match between Beacon/ProbeResp and EAPOL-Key msg 3/4Jouni Malinen39 hours1-0/+7
| | | | | | | | If the AP advertises RSN Extension element, it has to be advertised consistently in the unprotected (Beacon and Probe Response) and protected (EAPOL-Key msg 3/4) frames. Verify that this is the case. Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
* Replace int status/reason_code with u16 variableJouni Malinen2019-04-221-1/+1
| | | | | | | | | These cases are for the IEEE 802.11 Status Code and Reason Code and those fields are unsigned 16 bit values, so use the more appropriate type consistently. This is mainly to document the uses and to make the source code easier to understand. Signed-off-by: Jouni Malinen <j@w1.fi>
* DPP2: PFS for PTK derivationJouni Malinen2019-03-181-0/+1
| | | | | | | | | | Use Diffie-Hellman key exchange to derivate additional material for PMK-to-PTK derivation to get PFS. The Diffie-Hellman Parameter element (defined in OWE RFC 8110) is used in association frames to exchange the DH public keys. For backwards compatibility, ignore missing request/response DH parameter and fall back to no PFS in such cases. Signed-off-by: Jouni Malinen <jouni@codeaurora.org>

* Remove all PeerKey functionalityJouni Malinen2017-10-151-18/+0
| | | | | | | | | | | | | | | | | | | | | | | | This was originally added to allow the IEEE 802.11 protocol to be tested, but there are no known fully functional implementations based on this nor any known deployments of PeerKey functionality. Furthermore, PeerKey design in the IEEE Std 802.11-2016 standard has already been marked as obsolete for DLS and it is being considered for complete removal in REVmd. This implementation did not really work, so it could not have been used in practice. For example, key configuration was using incorrect algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in mapping to an invalid WPA_ALG_* value for the actual driver operation. As such, the derived key could not have been successfully set for the link. Since there are bugs in this implementation and there does not seem to be any future for the PeerKey design with DLS (TDLS being the future for DLS), the best approach is to simply delete all this code to simplify the EAPOL-Key handling design and to get rid of any potential issues if these code paths were accidentially reachable.

* DPP: Add new AKMJouni Malinen2017-06-191-0/+2
| | | | | | | | | | This new AKM is used with DPP when using the signed Connector to derive a PMK. Since the KCK, KEK, and MIC lengths are variable within a single AKM, this needs number of additional changes to get the PMK length delivered to places that need to figure out the lengths of the PTK components.

| | | | | | | | | | | This adds an option to configure wpa_supplicant to use the perfect forward secrecy option in FILS shared key authentication. A new build option CONFIG_FILS_SK_PFS=y can be used to include this functionality. A new runtime network profile parameter fils_dh_group is used to enable this by specifying which DH group to use. For example, fils_dh_group=19 would use FILS SK PFS with a 256-bit random ECP group. Signed-off-by: Jouni Malinen <j@w1.fi>

| | | | | | | | | | The RSN supplicant implementation needs to be updated to use the new BSSID whenever doing FILS authentication. Previously, this was only done when notifying association and that was too late for the case of reassociation. Fix this by providing the new BSSID when calling fils_process_auth().

* External persistent storage for PMKSA cache entriesJouni Malinen2016-12-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds new wpa_supplicant control interface commands PMKSA_GET and PMKSA_ADD that can be used to store PMKSA cache entries in an external persistent storage when terminating a wpa_supplicant process and then restore those entries when starting a new process. The previously added PMKSA-CACHE-ADDED/REMOVED events can be used to help in synchronizing the external storage with the memory-only volatile storage within wpa_supplicant. "PMKSA_GET <network_id>" fetches all stored PMKSA cache entries bound to a specific network profile. The network_id of the current profile is available with the STATUS command (id=<network_id). In addition, the network_id is included in the PMKSA-CACHE-ADDED/REMOVED events. The output of the PMKSA_GET command uses the following format: <BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration in seconds> <akmp> <opportunistic> For example: 02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30240 43200 1 0 02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 30240 43200 1 0 The PMKSA_GET command uses the following format: <network_id> <BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration in seconds> <akmp> <opportunistic> (i.e., "PMKSA_ADD <network_id> " prefix followed by a line of PMKSA_GET output data; however, the reauth_time and expiration values need to be updated by decrementing them by number of seconds between the PMKSA_GET and PMKSA_ADD commands) For example: PMKSA_ADD 0 02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30140 43100 1 0 PMKSA_ADD 0 02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 30140 43100 1 0 This functionality is disabled be default and can be enabled with CONFIG_PMKSA_CACHE_EXTERNAL=y build configuration option. It should be noted that this allows any process that has access to the wpa_supplicant control interface to use PMKSA_ADD command to fetch keying material (PMK), so this is for environments in which the control interface access is restricted.

* wpa_supplicant: Add GTK RSC relaxation workaroundMax Stepanov2015-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | Some APs may send RSC octets in EAPOL-Key message 3 of 4-Way Handshake or in EAPOL-Key message 1 of Group Key Handshake in the opposite byte order (or by some other corrupted way). Thus, after a successful EAPOL-Key exchange the TSC values of received multicast packets, such as DHCP, don't match the RSC one and as a result these packets are dropped on replay attack TSC verification. An example of such AP is Sapido RB-1732. Work around this by setting RSC octets to 0 on GTK installation if the AP RSC value is identified as a potentially having the byte order issue. This may open a short window during which older (but valid) group-addressed frames could be replayed. However, the local receive counter will be updated on the first received group-addressed frame and the workaround is enabled only if the common invalid cases are detected, so this workaround is acceptable as not decreasing security significantly. The wpa_rsc_relaxation global configuration property allows the GTK RSC workaround to be disabled if it's not needed. Signed-off-by: Max Stepanov <Max.Stepanov@intel.com>

* Pass TDLS peer capability information in tdls_mgmtSunil Dutt2014-03-271-1/+2
| | | | | | | | | | | | | | | While framing the TDLS Setup Confirmation frame, the driver needs to know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the VHT/HT operation / WMM parameter elements accordingly. Supplicant determines if the TDLS peer is VHT/HT/WMM capable based on the presence of the respective IEs in the received TDLS Setup Response frame. The host driver should not need to parse the received TDLS Response frame and thus, should be able to rely on the supplicant to indicate the capability of the peer through additional flags while transmitting the TDLS Setup Confirmation frame through tdls_mgmt operations.

* P2P: Add support for IP address assignment in 4-way handshakeJouni Malinen2014-01-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This new mechanism allows P2P Client to request an IPv4 address from the GO as part of the 4-way handshake to avoid use of DHCP exchange after 4-way handshake. If the new mechanism is used, the assigned IP address is shown in the P2P-GROUP-STARTED event on the client side with following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP address is included in the AP-STA-CONNECTED event on the GO side as a new ip_addr parameter. The IP address is valid for the duration of the association. The IP address pool for this new mechanism is configured as global wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask, ip_addr_star, ip_addr_end. For example: ip_addr_go= ip_addr_mask= ip_addr_start= ip_addr_end= DHCP mechanism is expected to be enabled at the same time to support P2P Devices that do not use the new mechanism. The easiest way of managing the IP addresses is by splitting the IP address range into two parts and assign a separate range for wpa_supplicant and DHCP server.
