242e857285 Extend domain_match and domain_suffix_match to allow list of values
These wpa_supplicant network profile parameters could be used to specify
a single match string that would be used against the dNSName items in
subjectAltName or CN. There may be use cases where more than one
alternative match string would be useful, so extend these to allow a
semicolon delimited list of values to be used (e.g.,
"example.org;example.com"). If any of the specified values matches any
of the dNSName/CN values in the server certificate, consider the
certificate as meeting this requirement.

dcc0ccd5b0 wolfSSL: Fix dNSName matching with domain_match and domain_suffix_match
Incorrect gen->type value was used to check whether subjectAltName
contained dNSName entries. This resulted in all domain_match and
domain_suffix_match entries failing to find a match and rejecting the
server certificate. Fix this by checking against the correct type
definition for dNSName.

3580ed8266 RADIUS server: Accept ERP keyName-NAI as user identity
Previously the EAP user database had to include a wildcard entry for ERP
to work since the keyName-NAI as User-Name in Access-Request would not
be recognized without such wildcard entry (that could point to any EAP
method). This is not ideal, so add a separate check to allow any stored
ERP keyName-NAI to be used for ERP without any requirement for the EAP
user database to contain a matching entry.

2ffd8076de FT/RRB: Pad RRB messages to at least minimum Ethernet frame length
Ethernet frames have minimum length of 64 octets and shorter frames may
end up getting arbitrary padding in the end. This would result in the
FT/RRB receiver rejecting the frame as an incorrectly protected one.
Work around this by padding the message so that it is never shorter than
the minimum Ethernet frame.

Unfortunately, this padding is apparently not enough with all Ethernet
devices and it is still possible to see extra two octet padding at the
end of the message even if larger frames are used (e.g., showed up with
128 byte frames). For now, work around this by trying to do AES-SIV
decryption with two octets shorter frame (ignore last two octets) if the
first attempt fails.

ff5f54e159 SAE: Reduce queue wait time for pending Authentication frames
The queue_len * 50 ms wait time was too large with the retransmission
timeouts used in the mesh case for SAE. The maximum wait of 750 ms was
enough to prevent successful completion of authentication after having
hit the maximum queue length. While the previous commit is enough to
allow this to complete successfully in couple of retries, it looks like
a smaller wait time should be used here even if it means potentially
using more CPU.

Drop the processing wait time to queue_len * 10 ms so that the maximum
wait time is 150 ms if the queue is full.

5e3a759cd4 SAE: Improved queuing policy for pending authentication frames
The previous design of simply queuing all SAE commit messages was not
exactly good at allowing recovery from a flooding state if the valid
peer used frequent retransmissions of the SAE message. This could
happen, e.g., with mesh BSSs using SAE. The frequent retransmissions and
restarts of SAE authentication combined with SAE confirm messages
bypassing the queue ended up in not being able to finish SAE exchange
successfully.

Fix this by modifying the queuing policy to queue SAE confirm messages
if there is a queued SAE commit message from the same peer so that the
messages within the same exchange do not get reordered. In addition,
replace queued SAE commit/confirm message if a new matching message is
received from the same peer STA. This is useful for the case where the
peer restarts SAE more quickly than the local end has time to process
the queued messages.

bf0021ede3 Allow fragmentation/RTS threshold to be disabled explicitly
hostapd configuration parameters fragm_threshold and rts_threshold were
documented to disable the threshold with value -1 and not change driver
configuration if the parameter is not included. However, -1 was mapped
into not changing the driver value, so the explicit disabling part did
not work.

Replace the default values for these to be -2 so that explicitly set
configuration value -1 can be distinguished from the case of not
including the parameter. Map the -1 value to a driver request to disable
the threshold. Ignore any error from this operation just in case to
avoid breaking functionality should some drivers not accept the (u32) -1
value as a threshold value request to disable the mechanism.
