-Subject: [PATCH] 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] 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] 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] 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] 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] 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] WNM: Ignore WNM-Sleep Mode Response without pending request
-
-Commit 03ed0a52393710be6bdae657d1b36efa146520e5 ('WNM: Ignore WNM-Sleep
-Mode Response if WNM-Sleep Mode has not been used') started ignoring the
-response when no WNM-Sleep Mode Request had been used during the
-association. This can be made tighter by clearing the used flag when
-successfully processing a response. This adds an additional layer of
-protection against unexpected retransmissions of the response frame.

-Subject: [PATCH] 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.

-Subject: [PATCH] WPA: Ignore unauthenticated encrypted EAPOL-Key data
-
-Ignore unauthenticated encrypted EAPOL-Key data in supplicant
-processing. When using WPA2, these are frames that have the Encrypted
-flag set, but not the MIC flag.
-
-When using WPA2, EAPOL-Key frames that had the Encrypted flag set but
-not the MIC flag, had their data field decrypted without first verifying
-the MIC. In case the data field was encrypted using RC4 (i.e., when
-negotiating TKIP as the pairwise cipher), this meant that
-unauthenticated but decrypted data would then be processed. An adversary
-could abuse this as a decryption oracle to recover sensitive information
-in the data field of EAPOL-Key messages (e.g., the group key).
-(CVE-2018-14526)

-Subject: OpenSSL: Avoid SSL*_use_default_passwd_cb()
-
-These functions are a bit awkward to use for one-off file loads, as
-suggested by the tls_clear_default_passwd_cb() logic. There was also
-some historical mess with OpenSSL versions and either not having per-SSL
-settings, having per-SSL settings but ignoring them, and requiring the
-per-SSL settings.
-
-Instead, loading the key with the lower-level functions seems a bit
-tidier and also allows abstracting away trying both formats, one after
-another.

-Subject: OpenSSL: Clear default_passwd_cb more thoroughly
-
-Previously, the pointer to strdup passwd was left in OpenSSL library
-default_passwd_cb_userdata and even the default_passwd_cb was left set
-on an error path. To avoid unexpected behavior if something were to
-manage to use there pointers, clear them explicitly once done with
-loading of the private key.
