Wireless access point daemon, patched with ubus support

A case was missing in the way wpa_supplicant was tracking the identity that is used when deriving MK if the EAP server does not follow the RFC guidance on using EAP method specific identity determination (i.e., AT_IDENTITY for EAP-SIM/AKA) combined with a fallback from fast re-authentication to full authentication. wpa_supplicant ended up using the actual identity instead of the last identity included in an EAP message even though MK derivation is supposed to use the identity that was included in the last AT_IDENTITY or in the EAP-Response/Identity if AT_IDENTITY was not used. This resulted in such an authentication attempt failing due to incorrect MK being derived and AT_MAC validation resulting in an mismatch. Fix this by checking for the case where fast re-authentication is attempted and the server recognizes the fast re-auth identity, but decides to fall back to full authentication without a separate EAP method specific identity exchange using AT_IDENTITY. This allows the fast re-auth identity from EAP-Response/Identity to be used in MK derivation in such cases. Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com> |

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2022, 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).
