22Subject: [PATCH 1/7] hostapd: Avoid key reinstallation in FT handshake
23
24Do not reinstall TK to the driver during Reassociation Response frame
25processing if the first attempt of setting the TK succeeded. This avoids
26issues related to clearing the TX/RX PN that could result in reusing
27same PN values for transmitted frames (e.g., due to CCM nonce reuse and
28also hitting replay protection on the receiver) and accepting replayed
29frames on RX side.
30
31This issue was introduced by the commit
320e84c25434e6a1f283c7b4e62e483729085b78d2 ('FT: Fix PTK configuration in
33authenticator') which allowed wpa_ft_install_ptk() to be called multiple
34times with the same PTK. While the second configuration attempt is
35needed with some drivers, it must be done only if the first attempt
36failed.

153Subject: [PATCH 2/7] Prevent reinstallation of an already in-use group key
154
155Track the current GTK and IGTK that is in use and when receiving a
156(possibly retransmitted) Group Message 1 or WNM-Sleep Mode Response, do
157not install the given key if it is already in use. This prevents an
158attacker from trying to trick the client into resetting or lowering the
159sequence counter associated to the group key.

407Subject: [PATCH 3/7] Extend protection of GTK/IGTK reinstallation of WNM-Sleep
408 Mode cases
409
410This extends the protection to track last configured GTK/IGTK value
411separately from EAPOL-Key frames and WNM-Sleep Mode frames to cover a
412corner case where these two different mechanisms may get used when the
413GTK/IGTK has changed and tracking a single value is not sufficient to
414detect a possible key reconfiguration.

661Subject: [PATCH 5/7] Fix PTK rekeying to generate a new ANonce
662
663The Authenticator state machine path for PTK rekeying ended up bypassing
664the AUTHENTICATION2 state where a new ANonce is generated when going
665directly to the PTKSTART state since there is no need to try to
666determine the PMK again in such a case. This is far from ideal since the
667new PTK would depend on a new nonce only from the supplicant.
668
669Fix this by generating a new ANonce when moving to the PTKSTART state
670for the purpose of starting new 4-way handshake to rekey PTK.

727Subject: [PATCH 6/7] TDLS: Reject TPK-TK reconfiguration
728
729Do not try to reconfigure the same TPK-TK to the driver after it has
730been successfully configured. This is an explicit check to avoid issues
731related to resetting the TX/RX packet number. There was already a check
732for this for TPK M2 (retries of that message are ignored completely), so
733that behavior does not get modified.
734
735For TPK M3, the TPK-TK could have been reconfigured, but that was
736followed by immediate teardown of the link due to an issue in updating
737the STA entry. Furthermore, for TDLS with any real security (i.e.,
738ignoring open/WEP), the TPK message exchange is protected on the AP path
739and simple replay attacks are not feasible.
740
741As an additional corner case, make sure the local nonce gets updated if
742the peer uses a very unlikely "random nonce" of all zeros.

861Subject: [PATCH 7/7] FT: Do not allow multiple Reassociation Response frames
862
863The driver is expected to not report a second association event without
864the station having explicitly request a new association. As such, this
865case should not be reachable. However, since reconfiguring the same
866pairwise or group keys to the driver could result in nonce reuse issues,
867be extra careful here and do an additional state check to avoid this
868even if the local driver ends up somehow accepting an unexpected
869Reassociation Response frame.
