While it is appropriate to try to retransmit the event to another
callback URL on a failure to initiate the HTTP client connection, there
is no point in trying the exact same operation multiple times in a row.
Replve the event_retry() calls with event_addr_failure() for these cases
to avoid busy loops trying to repeat the same failing operation.
These potential busy loops would go through eloop callbacks, so the
process is not completely stuck on handling them, but unnecessary CPU
would be used to process the continues retries that will keep failing
for the same reason.

More than about 700 character URL ended up overflowing the wpabuf used
for building the event notification and this resulted in the wpabuf
buffer overflow checks terminating the hostapd process. Fix this by
allocating the buffer to be large enough to contain the full URL path.
However, since that around 700 character limit has been the practical
limit for more than ten years, start explicitly enforcing that as the
limit or the callback URLs since any longer ones had not worked before
and there is no need to enable them now either.

wpa_supplicant disables PMKSA caching with FT-EAP by default due to
known interoperability issues with APs. This is allowed only if the
network profile is explicitly enabling caching with
ft_eap_pmksa_caching=1. However, the PMKID for such PMKSA cache entries
was still being configured to the driver and it was possible for the
driver to build an RSNE with the PMKID for SME-in-driver cases. This
could result in hitting the interop issue with some APs.
Fix this by skipping PMKID configuration to the driver fot FT-EAP AKM if
ft_eap_pmksa_caching=1 is not used in the network profile so that the
driver and wpa_supplicant behavior are in sync for this.

When a single hostapd process manages both the OWE and open BSS for
transition mode, owe_transition_ifname can be used to clone the
transition mode information (i.e., BSSID/SSID) automatically. When both
BSSs use ACS, the completion of ACS on the 1st BSS sets state to
HAPD_IFACE_ENABLED and the OWE transition mode information is updated
for all the other BSSs. However, the 2nd BSS is still in the ACS phase
and the beacon update messes up the state for AP startup and prevents
proper ACS competion.
If 2nd BSS is not yet enabled (e.g., in ACS), skip beacon update and

Documentation of the return values for wpa_parse_vendor_specific() and
wpa_parse_generic() were not accurate and the parsing results from these
were not really handled appropriately. There is no point in calling
wpa_parse_vendor_specific() if wpa_parse_generic() recognizes a KDE. Not
that this would break anything in practice, but still, it looks
confusing.
The part about handling wpa_parse_vendor_specific() return value can, at
least in theory, break some cases where an unexpectedly short KDE/vendor
specific element were present and something would need to be recognized
after it. That does not really happen with any standard compliant
implementation and this is unlikely to cause any real harm, but it is
clearer to handle this more appropriately even for any theoretical case,
including misbehavior of a peer device.
Instead of stopping parsing on too short vendor specific element,
continue parsing the following KDEs/IEs. Skip the
wpa_parse_vendor_specific() call when a KDE has been recognized. Also
fix the return value documentation for wpa_parse_generic() and remove
the useless return value from wpa_parse_vendor_specific().

While the Diffie-Hellman Parameter element is defined in RFC 8110
explicitly for use witht he OWE AKM, it has now been proposed to be used
with another AKM (DPP). Should any other AKM be extended in similar
manner in the future, the check against unexpected use could result in
additional interoperability issues. Remove that and instead, ignore the
unexpected Diffie-Hellman Parameter element if it is included in
(Re)Association Request frame when any other AKM is negotiated.

If the Enrollee indicates support for DPP R2 or newer, add Connector and

correctly by not setting key_mgmt=DPP based on Connector being present,

Add HE override support under the build parameter CONFIG_HE_OVERRIDES=y.

This requires a fallback to VHT on the 5 GHz band and to HT on the 2.4

There is no nl80211 support for configuring the driver to disable HE, so
for now, this applies only to IBSS and mesh cases.

hostapd (and wpa_supplicant in AP mode) was internally updating the STA
flags on disconnection cases to remove authorization and association.
However, some cases did not result in immediate update of the driver STA
entry. Update all such cases to send out the update to the driver as
well to reduce risk of race conditions where new frames might be
accepted for TX or RX after the port authorization or association has
been lost and configured keys are removed.
