6a34bd3007 HE: Use device HE capability instead of HT/VHT for 6 GHz IEs
Previously, 6 GHz Band Capability element was derived from HT and VHT
capabilities of the device. Removes such unnecessary dependency by
relying directly on the HE capability.

In addition, clean up the struct ieee80211_he_6ghz_band_cap definition

85aac526af WPS UPnP: Handle HTTP initiation failures for events more properly
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.

f7d268864a WPS UPnP: Fix event message generation using a long URL path
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.

5b78c8f961 WPS UPnP: Do not allow event subscriptions with URLs to other networks
The UPnP Device Architecture 2.0 specification errata ("UDA errata
16-04-2020.docx") addresses a problem with notifications being allowed
to go out to other domains by disallowing such cases. Do such filtering
for the notification callback URLs to avoid undesired connections to
external networks based on subscriptions that any device in the local
network could request when WPS support for external registrars is
enabled (the upnp_iface parameter in hostapd configuration).

215b4d8a72 FT: Do not add PMKID to the driver for FT-EAP if caching is disabled
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.

d578e890eb OWE: Skip beacon update of transition BSS if it is not yet enabled
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
defer OWE transition information cloning until the BSS is enabled.
