-Subject: [PATCH 1/8] hostapd: Avoid key reinstallation in FT handshake
-
-Do not reinstall TK to the driver during Reassociation Response frame
-processing if the first attempt of setting the TK succeeded. This avoids
-issues related to clearing the TX/RX PN that could result in reusing
-same PN values for transmitted frames (e.g., due to CCM nonce reuse and
-also hitting replay protection on the receiver) and accepting replayed
-frames on RX side.
-
-This issue was introduced by the commit
-0e84c25434e6a1f283c7b4e62e483729085b78d2 ('FT: Fix PTK configuration in
-authenticator') which allowed wpa_ft_install_ptk() to be called multiple
-times with the same PTK. While the second configuration attempt is
-needed with some drivers, it must be done only if the first attempt
-failed.
