42e69bda2a FILS: Add support for Cache Identifier in add/remove PMKSA
Add support for setting and deleting PMKSA cache entries based on FILS Cache
Identifer. Also additionally add support for sending PMK as part of
SET_PMKSA to enable driver to derive keys in case of FILS shared key
offload using PMKSA caching.

a6f3761f7d eap_proxy: Add support for SIM state change indication from eap_proxy
This registers a new callback to indicate change in SIM state. This
helps to do some clean up (more specifically pmksa_flush) based on the
state change of the SIM. Without this, the reconnection using the cached
PMKSA could happen though the SIM is changed.

Currently eap_proxy_sim_state corresponds to only SIM_STATE_ERROR. This
can be further extended.

3c108b7573 EAP peer: External server certificate chain validation
This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.

This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.

By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.

The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>

Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).

The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>

It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

73ed03f333 wpa_supplicant: Add GTK RSC relaxation workaround
Some APs may send RSC octets in EAPOL-Key message 3 of 4-Way Handshake
or in EAPOL-Key message 1 of Group Key Handshake in the opposite byte
order (or by some other corrupted way). Thus, after a successful
EAPOL-Key exchange the TSC values of received multicast packets, such as
DHCP, don't match the RSC one and as a result these packets are dropped
on replay attack TSC verification. An example of such AP is Sapido
RB-1732.

Work around this by setting RSC octets to 0 on GTK installation if the
AP RSC value is identified as a potentially having the byte order issue.
This may open a short window during which older (but valid)
group-addressed frames could be replayed. However, the local receive
counter will be updated on the first received group-addressed frame and
the workaround is enabled only if the common invalid cases are detected,
so this workaround is acceptable as not decreasing security
significantly. The wpa_rsc_relaxation global configuration property
allows the GTK RSC workaround to be disabled if it's not needed.

a250722f38 Try to set PMK only with key mgmt offload support in the driver
Previously, it was possible for the set_key() handler to be used with
WPA_ALG_PMK even if the driver did not indicate support for key
management offload. While this is not really supposed to result in any
difference, it makes the debug logs somewhat confusing. Avoid that by
using driver capability flag for key management offload as an additional
condition for setting the PMK.

a52410c29f Allow PSK/passphrase to be set only when needed
The new network profile parameter mem_only_psk=1 can be used to specify
that the PSK/passphrase for that network is requested over the control
interface (ctrl_iface or D-Bus) similarly to the EAP network parameter
requests. The PSK/passphrase can then be configured temporarily in a way
that prevents it from getting stored to the configuration file.

For example:

Event:
CTRL-REQ-PSK_PASSPHRASE-0:PSK or passphrase needed for SSID test-wpa2-psk

Response:
CTRL-RSP-PSK_PASSPHRASE-0:"qwertyuiop"

Note: The response value uses the same encoding as the psk network
profile parameter, i.e., passphrase is within double quotation marks.

483dd6a5e0 Include peer certificate always in EAP events
This makes it easier for upper layer applications to get information
regarding the server certificate without having to use a special
certificate probing connection. This provides both the SHA256 hash of
the certificate (to be used with ca_cert="hash://server/sha256/<hash>",
if desired) and the full DER encoded X.509 certificate so that upper
layer applications can parse and display the certificate easily or
extract fields from it for purposes like configuring an altsubject_match
or domain_suffix_match.

The old behavior can be configured by adding cert_in_cb=0 to
wpa_supplicant configuration file.

76db5b6b12 Work around broken AP PMKSA caching implementation
An interoperability issue with a deployed AP has been identified where
the connection fails due to that AP failing to operate correctly if
PMKID is included in the Association Request frame. To work around this,
allow EAPOL-Start packet to be transmitted on startWhen reaching 0 even
when trying to use PMKSA caching. In practice, this allows fallback to
full EAP authentication if the AP/Authenticator takes more than 1-2
seconds to initiate 4-way handshake for PMKSA caching or full EAP
authentication if there was no PMKSA cache match.

96ecea5eb1 Pass TDLS peer capability information in tdls_mgmt
While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the
VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the presence
of the respective IEs in the received TDLS Setup Response frame.

The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

25ef8529c1 P2P: Add support for IP address assignment in 4-way handshake
This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.

The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:

ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100

DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.

parameter.

1e8a6e7553 Remove unused wpa_supplicant_disassociate()
This function is now unused after the last couple of commits that
removed the last uses, so remove this to keep code simpler since all
places that disassociate, can use deauthentication instead.

e026159a8e EAP-SIM/AKA: Store pseudonym identity in configuration

wpa_supplicant restart) even if fast re-authentication data was cleared.
