Wireless access point daemon, patched with ubus support
b6d3fd05e3
PMKSA caching for the FT initial mobility domain association was fully defined in IEEE Std 802.11-2020. The state before that was unclear and there has been interoperability issues in this area, so use of PMKSA caching with FT-EAP has been disabled in wpa_supplicant by default. The wpa_supplicant and hostapd implementation of PMKSA caching for FT ended up using an earlier default mechanism (SHA-1) for deriving the PMKID when using the FT-EAP. This does not match what got defined in IEEE Std 802.11-2020, 12.11.2.5.2 (SHA256). It is not really desirable to use SHA-1 for anything with FT since the initial design of FT was based on SHA256. Furthermore, it is obviously not good to differ in behavior against the updated standard. As such, there is sufficient justification to change the implementation to use SHA256 here even though this ends up breaking backwards compatibility for PMKSA caching with FT-EAP. As noted above, this is still disabled in wpa_supplicant by default and this change results in PMKSA caching not working only in cases where it has been enabled explicitly with ft_eap_pmksa_caching=1. Those cases recover by falling back to full EAP authentication. Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com> |

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).
