FragAttacks: Fragmentation & Aggregation Attacks
66819b07b5
The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a backhaul STA through WPS. To enable this, the WPS Registrar offers a different set of credentials (backhaul credentials instead of fronthaul credentials) when the Multi-AP subelement is present in the WFA vendor extension element of the WSC M1 message. Add new configuration options to specify the backhaul credentials for the hostapd internal registrar: multi_ap_backhaul_ssid, multi_ap_backhaul_wpa_psk, multi_ap_backhaul_wpa_passphrase. These are only relevant for a fronthaul SSID, i.e., where multi_ap is set to 2 or 3. When these options are set, pass the backhaul credentials instead of the normal credentials when the Multi-AP subelement is present. Ignore the Multi-AP subelement if the backhaul config options are not set. Note that for an SSID which is fronthaul and backhaul at the same time (i.e., multi_ap == 3), this results in the correct credentials being sent anyway. The security to be used for the backaul BSS is fixed to WPA2PSK. The Multi-AP Specification only allows Open and WPA2PSK networks to be configured. Although not stated explicitly, the backhaul link is intended to be always encrypted, hence WPA2PSK. To build the credentials, the credential-building code is essentially copied and simplified. Indeed, the backhaul credentials are always WPA2PSK and never use per-device PSK. All the options set for the fronthaul BSS WPS are simply ignored.

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2019, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These programs are licensed under the BSD license (the one with advertisement clause removed). If you are submitting changes to the project, please see CONTRIBUTIONS file for more instructions. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
