Veerendranath Jakkam 80bcd7ecd1 FILS: Flush PMKSA entries on FILS connection failure
wpa_supplicant generates both a PMKSA cache entry and ERP keys upon
successful FILS connection and uses FILS authentication algorithm for
subsequent connections when either ERP keys or a PMKSA cache entry is
available.

In some cases, like AP/RADIUS server restart, both ERP keys and PMKSA
becomes invalid. But currently when an AP rejects an association,
wpa_supplicant marks only ERP keys as failed but not clearing PMKSA.

Since PMKSA is not cleared, consecutive connection attempts are still
happening with FILS authentication algorithm and connection attempts are
failing with the same association rejection again instead of trying to
recover from the state mismatch by deriving a new ERP key hierarchy.

Clear PMKSA entries as well on association rejection from an AP to allow
the following connection attempt to go with open authentication to
re-establish a valid ERP key hierarchy. Also, since clearing PMKSA
entries on unprotected (Re)Association Response frames could allow DoS
attack (reduce usability of PMKSA caching), clear PMKSA entries only
when ERP keys exists.

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).
