The current cfg80211 limit for the maximum NL80211_ATTR_PMK length is
48, so anything larger than that will result in the operation completely
failing. Since the PMKSA entries can be used without the PMK for most
purposes (the main use case for PMK currently is offloaded FILS
authentication), try to go ahead by configuring only the PMKID for the
case where 64-octet PMK is needed (which is currently limited to only
DPP with NIST P-521 and brainpoolP512r1 curves). This can fix DPP
connections with drivers that expect to get the PMKID through this

While the OpenSSL version of i2d_EC_PUBKEY() seemed to be able to use
the POINT_CONVERSION_COMPRESSED setting on the EC key, that did not seem
to work with BoringSSL. Since this is not exactly robust design, replace
use of i2d_EC_PUBKEY() with a custom routine that enforces the DPP rules
on SubjectPublicKeyInfo (compressed format of the public key,
ecPublicKey OID, parameters present and indicating the curve by OID).

This routine was previously implemented twice using i2d_EC_PUBKEY().
There is no need to duplicate that implementation and especially since
it looks like this implementation needs to be replaced for BoringSSL,
start by using a shared helper function for both locations so that there
is only a single place that uses i2d_EC_PUBKEY() to build the special
DPP bootstrapping key DER encoding.

This allows hostapd testing functionality to be forced to send out a

This is not really perfect since there is no convenient way of sending
out a single unencrypted frame in the current nl80211 design. The
monitor interface could likely still do this, but that's not really
supposed to be used anymore. For now, clear and restore TK during this

since it ends up clearing the TSC value on the AP side and that shows up

wpa_disable_eapol_key_retries=1 that can be used to disable
retransmission of EAPOL-Key frames that are used to install

similar to setting wpa_group_update_count=1 and
wpa_pairwise_update_count=1, but with no impact to message 1/4
retries and with extended timeout for messages 4/4 and group
message 2/2 to avoid causing issues with stations that may use
aggressive power saving have very long time in replying to the
EAPOL-Key messages.
This option can be used to work around key reinstallation attacks
on the station (supplicant) side in cases those station devices
cannot be updated for some reason. By removing the
retransmissions the attacker cannot cause key reinstallation with
a delayed frame transmission. This is related to the station side

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

The previous implementation ended up starting a new EAPOL-Key 4-way
handshake if the STA were to attempt to perform another association.
This resulted in immediate disconnection since the PTK was not ready for
configuring FILS TK at the point when EAPOL-Key msg 1/4 is sent out.
This is better than alloing the association to continue with the same TK
reconfigured, but not really ideal.
Address this potential sequence by not starting a new 4-way handshake on
the additional association attempt. Instead, allow the association to
complete, but do so without reconfiguring the TK to avoid potential
issues with PN reuse with the same TK.

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.

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.

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
ad00d64e7d ('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.

This extends the protection to track last configured GTK/IGTK value

Track the current GTK and IGTK that is in use and when receiving a

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
0e84c25434 ('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.

Commit 84751b98c1 ('WPS: Allow wildcard
UUID PIN to be used twice') relaxed the constraints on how many time a
wildcard PIN can be used to allow two attempts. However, it did this in
a way that could result in concurrent attempts resulting in the wildcard
PIN being invalidated even without the second attempt actually going as
far as trying to use the PIN and a WPS protocol run.
wildcard_uuid is a flag/counter set for wildcard PINs and it is
incremented whenever the PIN is retrieved by wps_registrar_get_pin().
Eventually it causes the wildcard PIN to be released, effectively
limiting the number of registration attempts with a wildcard PIN.
With the previous implementation, when the PIN is in use and locked
(PIN_LOCKED), it is not returned from wps_registrar_get_pin() but
wildcard_uuid is still incremented which can cause the PIN to be
released earlier and stations will have fewer registration attempts with
it. Fix this scenario by only incrementing wildcard_uuid if the PIN is
actually going to be returned and used.

This part is missing from IEEE Std 802.11ai-2016, but the lack of DHss
here means there would not be proper PFS for the case where PMKSA

with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that add DHss into FILS-Key-Data (and PTK, in practice) derivation for
the PMKSA caching case so that a unique ICK, KEK, and TK are derived
even when using the same PMK.

IEEE Std 802.11ai-2016 had missed a change in the Pairwise key hierarchy
clause (12.7.1.3 in IEEE Std 802.11-2016) and due to that, the previous
implementation ended up using HMAC-SHA-1 -based PMKID derivation. This
was not really the intent of the FILS design and that issue was fixed
during REVmd work with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that change FILS cases to use HMAC-SHA-256 and HMAC-SHA-384 based on the
negotiated AKM.
Update the implementation to match the new design. This changes the
rsn_pmkid() function to take in the more generic AKMP identifier instead
of a boolean identifying whether SHA256 is used.
Note: This is not backwards compatible, i.e., this breaks PMKSA caching
based on the initial ERP key hierarchy setup if only STA or AP side
implementation is updated. PMKSA caching based on FILS authentication
exchange is not impacted by this, though.
