+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.

+Subject: [PATCH 2/8] Prevent reinstallation of an already in-use group key
+
+Track the current GTK and IGTK that is in use and when receiving a
+(possibly retransmitted) Group Message 1 or WNM-Sleep Mode Response, do
+not install the given key if it is already in use. This prevents an
+attacker from trying to trick the client into resetting or lowering the
+sequence counter associated to the group key.

+Subject: [PATCH 3/8] Extend protection of GTK/IGTK reinstallation of WNM-Sleep
+ Mode cases
+
+This extends the protection to track last configured GTK/IGTK value
+separately from EAPOL-Key frames and WNM-Sleep Mode frames to cover a
+corner case where these two different mechanisms may get used when the
+GTK/IGTK has changed and tracking a single value is not sufficient to
+detect a possible key reconfiguration.

+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.

+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.

+Subject: [PATCH 6/8] TDLS: Reject TPK-TK reconfiguration
+
+Do not try to reconfigure the same TPK-TK to the driver after it has
+been successfully configured. This is an explicit check to avoid issues
+related to resetting the TX/RX packet number. There was already a check
+for this for TPK M2 (retries of that message are ignored completely), so
+that behavior does not get modified.
+
+For TPK M3, the TPK-TK could have been reconfigured, but that was
+followed by immediate teardown of the link due to an issue in updating
+the STA entry. Furthermore, for TDLS with any real security (i.e.,
+ignoring open/WEP), the TPK message exchange is protected on the AP path
+and simple replay attacks are not feasible.
+
+As an additional corner case, make sure the local nonce gets updated if
+the peer uses a very unlikely "random nonce" of all zeros.

+Subject: [PATCH 8/8] FT: Do not allow multiple Reassociation Response frames
+
+The driver is expected to not report a second association event without
+the station having explicitly request a new association. As such, this
+case should not be reachable. However, since reconfiguring the same
+pairwise or group keys to the driver could result in nonce reuse issues,
+be extra careful here and do an additional state check to avoid this
+even if the local driver ends up somehow accepting an unexpected
+Reassociation Response frame.
