25Subject: [PATCH 1/7] hostapd: Avoid key reinstallation in FT handshake
26
27Do not reinstall TK to the driver during Reassociation Response frame
28processing if the first attempt of setting the TK succeeded. This avoids
29issues related to clearing the TX/RX PN that could result in reusing
30same PN values for transmitted frames (e.g., due to CCM nonce reuse and
31also hitting replay protection on the receiver) and accepting replayed
32frames on RX side.
33
34This issue was introduced by the commit
350e84c25434e6a1f283c7b4e62e483729085b78d2 ('FT: Fix PTK configuration in
36authenticator') which allowed wpa_ft_install_ptk() to be called multiple
37times with the same PTK. While the second configuration attempt is
38needed with some drivers, it must be done only if the first attempt
39failed.

154Subject: [PATCH 2/7] Prevent reinstallation of an already in-use group key
155
156Track the current GTK and IGTK that is in use and when receiving a
157(possibly retransmitted) Group Message 1 or WNM-Sleep Mode Response, do
158not install the given key if it is already in use. This prevents an
159attacker from trying to trick the client into resetting or lowering the
160sequence counter associated to the group key.

409Subject: [PATCH 3/7] Extend protection of GTK/IGTK reinstallation of WNM-Sleep
410 Mode cases
411
412This extends the protection to track last configured GTK/IGTK value
413separately from EAPOL-Key frames and WNM-Sleep Mode frames to cover a
414corner case where these two different mechanisms may get used when the
415GTK/IGTK has changed and tracking a single value is not sufficient to
416detect a possible key reconfiguration.

656Subject: [PATCH 5/7] Fix PTK rekeying to generate a new ANonce
657
658The Authenticator state machine path for PTK rekeying ended up bypassing
659the AUTHENTICATION2 state where a new ANonce is generated when going
660directly to the PTKSTART state since there is no need to try to
661determine the PMK again in such a case. This is far from ideal since the
662new PTK would depend on a new nonce only from the supplicant.
663
664Fix this by generating a new ANonce when moving to the PTKSTART state
665for the purpose of starting new 4-way handshake to rekey PTK.

723Subject: [PATCH 6/7] TDLS: Reject TPK-TK reconfiguration
724
725Do not try to reconfigure the same TPK-TK to the driver after it has
726been successfully configured. This is an explicit check to avoid issues
727related to resetting the TX/RX packet number. There was already a check
728for this for TPK M2 (retries of that message are ignored completely), so
729that behavior does not get modified.
730
731For TPK M3, the TPK-TK could have been reconfigured, but that was
732followed by immediate teardown of the link due to an issue in updating
733the STA entry. Furthermore, for TDLS with any real security (i.e.,
734ignoring open/WEP), the TPK message exchange is protected on the AP path
735and simple replay attacks are not feasible.
736
737As an additional corner case, make sure the local nonce gets updated if
738the peer uses a very unlikely "random nonce" of all zeros.

857Subject: [PATCH 7/7] FT: Do not allow multiple Reassociation Response frames
858
859The driver is expected to not report a second association event without
860the station having explicitly request a new association. As such, this
861case should not be reachable. However, since reconfiguring the same
862pairwise or group keys to the driver could result in nonce reuse issues,
863be extra careful here and do an additional state check to avoid this
864even if the local driver ends up somehow accepting an unexpected
865Reassociation Response frame.
