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.

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.

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.

HS 2.0: Add mechanism for disabling DGAF disable_dgaf=1 in hostapd.conf can now be used to disable downstream group-addressed forwarding (DGAF). In this configuration, a unique GTK (and IGTK) is provided to each STA in the BSS to make sure the keys do not match and no STA can forge group-addressed frames. An additional mechanism in the AP needs to be provided to handle some group-addressed frames, e.g., by converting DHCP packets to unicast IEEE 802.11 frames regardless of their destination IP address and by providing Proxy ARP functionality.

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.

hostapd: Fix a regression in TKIP countermeasures processing Commit 296a34f0c1730416bf2a61ab78690be43d82a3c0 changed hostapd to remove the internal STA entry at the beginning of TKIP countermeasures. However, this did not take into account the case where this is triggered by an EAPOL-Key error report from a station. In such a case, WPA authenticator state machine may continue processing after having processed the error report. This could result in use of freed memory. Fix this by stopping WPA processing if the STA entry got removed. Signed-hostap: 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.

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.

Fix init of group state machine for static VLANs This ensures that group key is set as long as the interface exists. Additionally, ifconfig_up is needed as wpa_group will enter FATAL_FAILURE if the interface is still down. Also vlan_remove_dynamic() is moved after wpa_auth_sta_deinit() so vlan_remove_dynamic() can check it was the last user of the wpa_group. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>
