Similarly to the wpa_supplicant_select_config() case,
wpa_get_beacon_ie() needs to handle the special case for OWE transition
mode where the SSID in the network profile does not match the SSID of
the OWE BSS (that has a hidden, random SSID). Accept such a BSS in case
the current scan results needs to be fetched for verifying EAPOL-Key msg
3/4 IEs.

It is possible for the hidden OWE BSS to be found based on SSID-specific
scan (e.g., from the special OWE scan mechanism). In that sequence, the
previously used learning of OWE BSS was skipped since the SSID was
already present in the BSS entry. This could result in not being able to
find a matching BSS entry for the OWE BSS in transition mode.
Fix this by adding the BSS flag for transition mode based on SSID
matching against currently enabled OWE network profiles in addition to
the previous mechanism.

The "unexpected" change of SSID between the current network profile
(which uses the SSID from the open BSS in OWE transition mode) and the
association with the OWE BSS (which uses a random, hidden SSID) resulted
in wpa_supplicant incorrectly determining that this was a
driver-initiated BSS selection ("Driver-initiated BSS selection changed
the SSID to <the random SSID from OWE BSS>" in debug log).
This ended up with updating security parameters based on the network
profile inwpa_supplicant_set_suites() instead of using the already
discovered information from scan results. In particular, this cleared
the RSN supplicant state machine information of AP RSNE and resulted in
having to fetch the scan results for the current BSS when processing
EAPOL-Key msg 3/4.
Fix this by recognizing the special case for OWE transition mode where
the SSID for the associated AP does not actually match the SSID in the
network profile.

The new hostapd configuration parameter rsne_override_eapol can now be
used similarly to the previously added rsnxe_override_eapol to override
(replace contents or remove) RSNE in EAPOL-Key msg 3/4. This can be used
for station protocol testing to verify sufficient checks for RSNE
modification between the Beacon/Probe Response frames and EAPOL-Key msg
3/4.

Previous implementation was determining whether the override value was
set based on its length being larger than zero. Replace this with an
explicit indication of whether the parameter is set to allow zero length
replacement, i.e., remove of RSNXE from EAPOL-Key msg 3/4.
In addition, move IE replacement into a more generic helper function to
allow this to be used with other IEs as well.

The 4-address frames WDS design in mac80211 uses VLAN interfaces
similarly to the way VLAN interfaces based on VLAN IDs are used. The EAP
authentication case ended up overriding the WDS specific assignment even
when the RADIUS server did not assign any specific VLAN for the STA.
This broke WDS traffic.
Fix this by skipping VLAN assignment to VLAN ID 0 for STAs that have
been detected to use 4-address frames.

The resource-load-started cannot be used to replace the older
resource-request-starting signal and as such, the final redirect to the
special http://localhost:12345/ URL did not work. Use the decide-policy
signal for navigation action instead.
Also remove the attempt to modify the request URI from
resource-load-started since that is not going to work either. This is
not really critical for functionality, but could eventually be replaced
with a handler for the WebKitWebPage send-request signal.

Some test case sequences seemed to prevent the station from completing
the first OBSS scan (that scan was aborted) and that resulted in failing
the test case because the AP had not received any report in time. Wait
for scan completion and allow additional scans before timing out to
avoid indicating incorrect AP behavior in cases where the report was not
even received.

The initial implementation of the PTK derivation workaround for
interoperability with older OWE implementations forced
WPA_KEY_MGMT_PSK_SHA256 to be used for all of PTK derivation. While that
is needed for selecting which hash algorithm to use, this was also
changing the length of the PTK components and by doing so, did not
actually address the backwards compatibility issue.
Fix this by forcing SHA256 as the hash algorithm in PTK derivation
without changing the PTK length calculation for OWE when
owe_ptk_workaround is enabled.

I'm still not sure why we install unicast WEP keys also as default

Always report an error when NL80211_CMD_SET_KEY can't set a key to
default.
The old ioctl-based design used a single command to add, set, and delete
a key and had to ignore ENOENT for key deletions. It looks like that
special handling was also ported for NL80211_CMD_NEW_KEY and
NL80211_CMD_SET_KEY instead only for NL80211_CMD_DEL_KEY.

Upon radar detection we used to search channels with the same bandwidth.

In the normal case hostapd_disable_iface() and hostapd_enable_iface()
will be done while switching to another DFS channel upon radar
detection. In certain scenarios radar detected event can come while
hostapd_disable_iface() is in progress and iface->current_mode will be
NULL in that scenario. Previously, we did not check for this scenario
and proceeded with the radar detection logic which can trigger a
segmentation fault. To fix this, avoid proceeding the radar detection
event if iface->current_mode is NULL.
