+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.
