-Subject: [PATCH 5/8] Fix PTK rekeying to generate a new ANonce
-
-The Authenticator state machine path for PTK rekeying ended up bypassing
-the AUTHENTICATION2 state where a new ANonce is generated when going
-directly to the PTKSTART state since there is no need to try to
-determine the PMK again in such a case. This is far from ideal since the
-new PTK would depend on a new nonce only from the supplicant.
-
-Fix this by generating a new ANonce when moving to the PTKSTART state
-for the purpose of starting new 4-way handshake to rekey PTK.
