22Subject: [PATCH 1/8] 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.

196Subject: [PATCH 2/8] Prevent reinstallation of an already in-use group key
197
198Track the current GTK and IGTK that is in use and when receiving a
199(possibly retransmitted) Group Message 1 or WNM-Sleep Mode Response, do
200not install the given key if it is already in use. This prevents an
201attacker from trying to trick the client into resetting or lowering the
202sequence counter associated to the group key.

446Subject: [PATCH 3/8] Extend protection of GTK/IGTK reinstallation of WNM-Sleep
447 Mode cases
448
449This extends the protection to track last configured GTK/IGTK value
450separately from EAPOL-Key frames and WNM-Sleep Mode frames to cover a
451corner case where these two different mechanisms may get used when the
452GTK/IGTK has changed and tracking a single value is not sufficient to
453detect a possible key reconfiguration.

630Subject: [PATCH 4/8] Prevent installation of an all-zero TK
631
632Properly track whether a PTK has already been installed to the driver
633and the TK part cleared from memory. This prevents an attacker from
634trying to trick the client into installing an all-zero TK.
635
636This fixes the earlier fix in commit
637ad00d64e7d8827b3cebd665a0ceb08adabf15e1e ('Fix TK configuration to the
638driver in EAPOL-Key 3/4 retry case') which did not take into account
639possibility of an extra message 1/4 showing up between retries of
640message 3/4.

709Subject: [PATCH 5/8] Fix PTK rekeying to generate a new ANonce
710
711The Authenticator state machine path for PTK rekeying ended up bypassing
712the AUTHENTICATION2 state where a new ANonce is generated when going
713directly to the PTKSTART state since there is no need to try to
714determine the PMK again in such a case. This is far from ideal since the
715new PTK would depend on a new nonce only from the supplicant.
716
717Fix this by generating a new ANonce when moving to the PTKSTART state
718for the purpose of starting new 4-way handshake to rekey PTK.

773Subject: [PATCH 6/8] TDLS: Reject TPK-TK reconfiguration
774
775Do not try to reconfigure the same TPK-TK to the driver after it has
776been successfully configured. This is an explicit check to avoid issues
777related to resetting the TX/RX packet number. There was already a check
778for this for TPK M2 (retries of that message are ignored completely), so
779that behavior does not get modified.
780
781For TPK M3, the TPK-TK could have been reconfigured, but that was
782followed by immediate teardown of the link due to an issue in updating
783the STA entry. Furthermore, for TDLS with any real security (i.e.,
784ignoring open/WEP), the TPK message exchange is protected on the AP path
785and simple replay attacks are not feasible.
786
787As an additional corner case, make sure the local nonce gets updated if
788the peer uses a very unlikely "random nonce" of all zeros.

907Subject: [PATCH 8/8] FT: Do not allow multiple Reassociation Response frames
908
909The driver is expected to not report a second association event without
910the station having explicitly request a new association. As such, this
911case should not be reachable. However, since reconfiguring the same
912pairwise or group keys to the driver could result in nonce reuse issues,
913be extra careful here and do an additional state check to avoid this
914even if the local driver ends up somehow accepting an unexpected
915Reassociation Response frame.
