Remove src/common from default header file path This makes it clearer which files are including header from src/common. Some of these cases should probably be cleaned up in the future not to do that. In addition, src/common/nl80211_copy.h and wireless_copy.h were moved into src/drivers since they are only used by driver wrappers and do not need to live in src/common.

FT: Replace inter-AP protocol with use of OUI Extended Ethertype Replace the previously used extension of IEEE 802.11 managed Ethertype 89-0d (originally added for Remote Request/Response in IEEE 802.11r) with Ethertype 88-b7 (OUI Extended EtherType) for FT inter-AP communication. The new design uses a more properly assigned identifier for the messages. This assigns the OUI 00:13:74 vendor-specific subtype 0x0001 for the new hostapd AP-to-AP communication purposes. Subtypes 1 (PULL), 2 (RESP), and 3 (PUSH) are also assigned in this commit for the R0KH-R1KH protocol. This breaks backward compatibility, i.e., hostapd needs to be updated on all APs at the same time to allow FT to remain functional. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

FT RRB: Add msg replay and msg delay protection This adds a counter and adds sequence numbering to FT RRB packets. The sequence number is checked against r0kh/r1kh sequence number cache. Special attention is needed in case the remote AP reboots and thus loses its state. I prefer it to recover automatically even without synchronized clocks. Therefore an identifier called dom is generated randomly along the initial sequence number. If the dom transmitted does not match or the sequence number is not in the range currently expected, the sender is asked for a fresh confirmation of its currently used sequence numbers. The packet that triggered this is cached and processed again later. Additionally, in order to ensure freshness, the remote AP includes an timestamp with its messages. It is then verified that the received messages are indeed fresh by comparing it to the older timestamps received and the time elapsed since then. Therefore FT_RRB_TIMESTAMP is no longer needed. This assigns new OUI 00:13:74 vendor-specific subtype 0x0001 subtypes: 4 (SEQ_REQ) and 5 (SEQ_RESP).

FT: Add support for wildcard R0KH/R1KH Enable use of FT RRB without configuring each other AP locally. Instead, broadcast messages are exchanged to discover APs within the local network. When an R0KH or R1KH is discovered, it is cached for one day. When a station uses an invalid or offline r0kh_id, requests are always broadcast. In order to avoid this, if r0kh does not reply, a temporary blacklist entry is added to r0kh_list. To avoid blocking a valid r0kh when a non-existing pmk_r0_name is requested, r0kh is required to always reply using a NAK. Resend requests a few times to ensure blacklisting does not happen due to small packet loss. To free newly created stations later, the r*kh_list start pointer in conf needs to be updateable from wpa_auth_ft.c, where only wconf is accessed.

This breaks backward compatibility, i.e., hostapd needs to be updated on all APs at the same time to allow FT to remain functional. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

FT RRB: Add msg replay and msg delay protection This adds a counter and adds sequence numbering to FT RRB packets. The sequence number is checked against r0kh/r1kh sequence number cache. Special attention is needed in case the remote AP reboots and thus loses its state. I prefer it to recover automatically even without synchronized clocks. Therefore an identifier called dom is generated randomly along the initial sequence number. If the dom transmitted does not match or the sequence number is not in the range currently expected, the sender is asked for a fresh confirmation of its currently used sequence numbers. The packet that triggered this is cached and processed again later. Additionally, in order to ensure freshness, the remote AP includes an timestamp with its messages. It is then verified that the received messages are indeed fresh by comparing it to the older timestamps received and the time elapsed since then. Therefore FT_RRB_TIMESTAMP is no longer needed. This assigns new OUI 00:13:74 vendor-specific subtype 0x0001 subtypes: 4 (SEQ_REQ) and 5 (SEQ_RESP). This breaks backward compatibility, i.e., hostapd needs to be updated on all APs at the same time to allow FT to remain functional. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

Added support for enforcing frequent PTK rekeying Added a new configuration option, wpa_ptk_rekey, that can be used to enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP deficiencies. This can be set either by the Authenticator (to initiate periodic 4-way handshake to rekey PTK) or by the Supplicant (to request Authenticator to rekey PTK). With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP keys will not be used for more than 10 minutes which may make some attacks against TKIP more difficult to implement.

Defaults set to current hardcoded value (4). Some stations may suffer from frequent deauthentications due to GTK rekey failures: EAPOL 1/2 frame is not answered during the total timeout period of currently ~3.5 seconds. For example, a Galaxy S6 with Android 6.0.1 appears to go into power save mode for up to 5 seconds. Increasing wpa_group_update_count to 6 fixed this issue.

Optional AP side workaround for key reinstallation attacks This adds a new hostapd configuration parameter wpa_disable_eapol_key_retries=1 that can be used to disable retransmission of EAPOL-Key frames that are used to install keys (EAPOL-Key message 3/4 and group message 1/2). This is similar to setting wpa_group_update_count=1 and wpa_pairwise_update_count=1, but with no impact to message 1/4 retries and with extended timeout for messages 4/4 and group message 2/2 to avoid causing issues with stations that may use aggressive power saving have very long time in replying to the EAPOL-Key messages. This option can be used to work around key reinstallation attacks on the station (supplicant) side in cases those station devices cannot be updated for some reason. By removing the retransmissions the attacker cannot cause key reinstallation with a delayed frame transmission. This is related to the station side vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, and CVE-2017-13081. This workaround might cause interoperability issues and reduced robustness of key negotiation especially in environments with heavy traffic load due to the number of attempts to perform the key exchange is reduced significantly. As such, this workaround is disabled by default (unless overridden in build configuration). To enable this, set the parameter to 1. It is also possible to enable this in the build by default by adding the following to the build configuration: CFLAGS += -DDEFAULT_WPA_DISABLE_EAPOL_KEY_RETRIES=1 Signed-off-by: Jouni Malinen <j@w1.fi>

Work around SNonce updates on EAPOL-Key 1/4 retransmission Some deployed supplicants update their SNonce for every receive EAPOL-Key message 1/4 even when these messages happen during the same 4-way handshake. Furthermore, some of these supplicants fail to use the first SNonce that they sent and derive an incorrect PTK using another SNonce that does not match with what the authenticator is using from the first received message 2/4. This results in failed 4-way handshake whenever the EAPOL-Key 1/4 retransmission timeout is reached. The timeout for the first retry is fixed to 100 ms in the IEEE 802.11 standard and that seems to be short enough to make it difficult for some stations to get the response out before retransmission. Work around this issue by increasing the initial EAPOL-Key 1/4 timeout by 1000 ms (i.e., total timeout of 1100 ms) if the station acknowledges reception of the EAPOL-Key frame. If the driver does not indicate TX status for EAPOL frames, use longer initial timeout (1000 ms) unconditionally.

FT: Allow PMK-R0 and PMK-R1 for FT-PSK to be generated locally Station should be able to connect initially without ft_pmk_cache filled, so the target AP has the PSK available and thus the same information as the origin AP.

This patch introduces the generation of the required PMKs locally for FT-PSK. Additionally, PMK-R0 is not stored (and thus pushed) for FT-PSK. So for FT-PSK networks, no configuration of inter-AP communication is needed anymore when using ft_psk_generate_local=1 configuration.

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=192.168.42.1 ip_addr_mask=255.255.255.0 ip_addr_start=192.168.42.2 ip_addr_end=192.168.42.100 DHCP mechanism is expected to be enabled at the same time to support P2P Devices that do not use the new mechanism.

FILS: Accept another (Re)Association Request frame during an association The previous implementation ended up starting a new EAPOL-Key 4-way handshake if the STA were to attempt to perform another association. This resulted in immediate disconnection since the PTK was not ready for configuring FILS TK at the point when EAPOL-Key msg 1/4 is sent out. This is better than alloing the association to continue with the same TK reconfigured, but not really ideal. Address this potential sequence by not starting a new 4-way handshake on the additional association attempt. Instead, allow the association to complete, but do so without reconfiguring the TK to avoid potential issues with PN reuse with the same TK. Signed-off-by: Jouni Malinen <j@w1.fi>

And the MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache, wpa_supplicant can skip commit message creation which can use significant CPU resources.

mesh: Add support for PMKSA caching This patch add functionality of mesh SAE PMKSA caching. If the local STA already has peer's PMKSA entry in the cache, skip SAE authentication and start AMPE with the cached value. If the peer does not support PMKSA caching or does not have the local STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry of the peer will be removed. Then STA retries with ordinary SAE authentication. If the peer does not support PMKSA caching and the local STA uses no_auto_peer=1, the local STA can not retry SAE authentication because NEW_PEER_CANDIDATE event cannot start SAE authentication when no_auto_peer=1.

Work around SNonce updates on EAPOL-Key 1/4 retransmission Some deployed supplicants update their SNonce for every receive EAPOL-Key message 1/4 even when these messages happen during the same 4-way handshake. Furthermore, some of these supplicants fail to use the first SNonce that they sent and derive an incorrect PTK using another SNonce that does not match with what the authenticator is using from the first received message 2/4. This results in failed 4-way handshake whenever the EAPOL-Key 1/4 retransmission timeout is reached. The timeout for the first retry is fixed to 100 ms in the IEEE 802.11 standard and that seems to be short enough to make it difficult for some stations to get the response out before retransmission. Work around this issue by increasing the initial EAPOL-Key 1/4 timeout by 1000 ms (i.e., total timeout of 1100 ms) if the station acknowledges reception of the EAPOL-Key frame. If the driver does not indicate TX status for EAPOL frames, use longer initial timeout (1000 ms) unconditionally.

FT: Differentiate between FT for station and for AP in build Previously, CONFIG_IEEE80211R enabled build that supports FT for both station mode and AP mode. However, in most wpa_supplicant cases only station mode FT is required and there is no need for AP mode FT. Add support to differentiate between station mode FT and AP mode FT in wpa_supplicant builds by adding CONFIG_IEEE80211R_AP that should be used when AP mode FT support is required in addition to station mode FT. This allows binary size to be reduced for builds that require only the station side FT functionality. Signed-off-by: Ilan Peer <ilan.peer@intel.com>

The new design uses a more properly assigned identifier for the messages. This assigns the OUI 00:13:74 vendor-specific subtype 0x0001 for the new hostapd AP-to-AP communication purposes. Subtypes 1 (PULL), 2 (RESP), and 3 (PUSH) are also assigned in this commit for the R0KH-R1KH protocol. This breaks backward compatibility, i.e., hostapd needs to be updated on all APs at the same time to allow FT to remain functional. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

FT RRB: Add msg replay and msg delay protection This adds a counter and adds sequence numbering to FT RRB packets. The sequence number is checked against r0kh/r1kh sequence number cache. Special attention is needed in case the remote AP reboots and thus loses its state. I prefer it to recover automatically even without synchronized clocks. Therefore an identifier called dom is generated randomly along the initial sequence number. If the dom transmitted does not match or the sequence number is not in the range currently expected, the sender is asked for a fresh confirmation of its currently used sequence numbers. The packet that triggered this is cached and processed again later. Additionally, in order to ensure freshness, the remote AP includes an timestamp with its messages. It is then verified that the received messages are indeed fresh by comparing it to the older timestamps received and the time elapsed since then. Therefore FT_RRB_TIMESTAMP is no longer needed. This assigns new OUI 00:13:74 vendor-specific subtype 0x0001 subtypes: 4 (SEQ_REQ) and 5 (SEQ_RESP). This breaks backward compatibility, i.e., hostapd needs to be updated on all APs at the same time to allow FT to remain functional. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

FT: Add support for wildcard R0KH/R1KH Enable use of FT RRB without configuring each other AP locally. Instead, broadcast messages are exchanged to discover APs within the local network. When an R0KH or R1KH is discovered, it is cached for one day. When a station uses an invalid or offline r0kh_id, requests are always broadcast. In order to avoid this, if r0kh does not reply, a temporary blacklist entry is added to r0kh_list. To avoid blocking a valid r0kh when a non-existing pmk_r0_name is requested, r0kh is required to always reply using a NAK. Resend requests a few times to ensure blacklisting does not happen due to small packet loss. To free newly created stations later, the r*kh_list start pointer in conf needs to be updateable from wpa_auth_ft.c, where only wconf is accessed.

FT: Differentiate between FT for station and for AP in build Previously, CONFIG_IEEE80211R enabled build that supports FT for both station mode and AP mode. However, in most wpa_supplicant cases only station mode FT is required and there is no need for AP mode FT. Add support to differentiate between station mode FT and AP mode FT in wpa_supplicant builds by adding CONFIG_IEEE80211R_AP that should be used when AP mode FT support is required in addition to station mode FT. This allows binary size to be reduced for builds that require only the station side FT functionality. Signed-off-by: Ilan Peer <ilan.peer@intel.com>

P2P: Add support for IP address assignment in 4-way handshake 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=192.168.42.1 ip_addr_mask=255.255.255.0 ip_addr_start=192.168.42.2 ip_addr_end=192.168.42.100 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.

Extend RESEND_* test commands to allow forcing plaintext TX This allows hostapd testing functionality to be forced to send out a plaintext EAPOL-Key frame with the RESEND_* command. That can be useful in seeing how the station behaves if an unencrypted EAPOL frame is received when TK is already configured. This is not really perfect since there is no convenient way of sending out a single unencrypted frame in the current nl80211 design. The monitor interface could likely still do this, but that's not really supposed to be used anymore. For now, clear and restore TK during this operation. The restore part is not really working correctly, though, since it ends up clearing the TSC value on the AP side and that shows up as replay protection issues on the station. Anyway, this is sufficient to generate sniffer captures to analyze station behavior. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
