+Subject: [PATCH 4/8] Prevent installation of an all-zero TK
+
+Properly track whether a PTK has already been installed to the driver
+and the TK part cleared from memory. This prevents an attacker from
+trying to trick the client into installing an all-zero TK.
+
+This fixes the earlier fix in commit
+ad00d64e7d8827b3cebd665a0ceb08adabf15e1e ('Fix TK configuration to the
+driver in EAPOL-Key 3/4 retry case') which did not take into account
+possibility of an extra message 1/4 showing up between retries of
+message 3/4.
