eecaceed8f tests: Remove eht_5ghz_80mhz_puncturing_override_1 for now
mac80211 has been modified to reject the configuration that is used in
this test case. For now, remove this until the puncturing of the second
20 MHz segment can be handled in a manner that allows mac80211 STA to
use EHT.

010d8d10ed EHT: Use eht_oper_puncturing_override when constructing VHT elements
The testing functionality for overriding EHT puncturing bitmap was
applied only for the EHT elements. The mac80211 has been updated to
enforce compartibility between EHT and HT/VHT information and that made
the related test cases fail. Apply the override value for VHT element
generation to avoid some of those issues.

0a321d1733 tests: Fix fuzzing tester for WNM
Processing of WNM frames can results in a lookup of the current BSS
table. As such, the testing tool needs to initialize the BSS table to
avoid NULL pointer dereferences. This is not an issue that would show up
with real production uses with wpa_supplicant since wpa_bss_init() is
called there.

The wpa_supplicant implementation for building the Supported Operating

9e90486bce 2-octet operating classes in Support Operating Classes element
A previous workaround was used to move the special operating class 130
to the end of the Supported Operating Classes element to avoid getting
any following entry being ignored or misunderstood. That is not really
the correct way of encoding the special cases, i.e., 80+80 MHz channels
that use two nonadjacent frequency segments.

Add support for encoding the 80+80 MHz channel with the 2-octet
operating class design using the Operating Class Duple sequence field of
the Supported Operating Classes element instead of listing the operating
classes that have the 80+ behavior limit set indication in Table E-4
(i.e., opclass 130 and 135) as 1-octet operating classes in the
Operating Classes field.

b653420a23 AP MLD: Set link address only when non-AP MLD is not added to driver
Once the non-AP MLD is added to the driver, the driver handles the
address translation so that hostapd receives Management frames with
SA/DA being translated into MLD MAC addresses.

If the Authentication frmae is retransmitted with transaction being 1,
SA of the retransmitted Authentication frame is translated into the MLD
MAC address by the driver, and then in the function handle_auth(),
sta->mld_info.links[].peer_addr would be replaced by the MLD MAC address
even though it is supposed to be the link address.

Therefore, update the MLD information only when the STA has not yet been
added into the driver to avoid replacing the previously determined link
address with the MLD MAC address.

e5b7e5b900 wpa_supplicant: Fix ignoring boundary 0 in config parser
The following config file contains invalid items:
----
filter_rssi=1234 # should be rejected

network={
 mode=-1 # should be rejected
 ssid="ssid"
 psk="password"

----
But it is accepted by the config parser. The issue is due to using NULL
to represent no limit. If a boundary is set to 0, it's disregarded.
Fix this.
Note that string parser is not affected as length cannot be negative and
we are not limiting any string to be always empty.

e508c070c4 WNM: Keep BTM information until connection completes
In the MLD case, the information from the transition management request
is relevant during the association process in order to filter out links
that were disallowed by the BTM request. Also, the information remains
useful should a connection attempt fail.

To enable these scenarios, keep the information around until the
connection has completed. As this might make it impossible to establish
a connection, also clear this information at the same time that a normal
BSS ignore is cleared to avoid getting stuck in case the transition
fails unexpectedly.

17a2aa822c WNM: Follow BTM procedure if the last link is dropped
If the last link is dropped, it makes sense to follow the BTM procedure.
However, in that case we need to prevent reconnection to this link
specifically, while if the AP MLD is terminating we need to forbid
connecting to the AP MLD.

As such, add a new variable to track the BSSID or AP MLD MAC address.
Which one it refers to depends on whether wnm_link_removal is set.

This also simplifies the check in wnm_is_bss_excluded() and untangles it
from wpa_s->current_bss.

20ed289a78 WNM: Clean up old scan data processing
When receiving a BTM request, wpa_supplicant would try to fetch new
results from the driver, and, independently of that, would also process
the latest scan results that were partially updated by the previous
fetch.

Simplify the logic by using wpa_supplicant_get_scan_results() directly
and then process the old scan data as usual. However, this data may be
outdated, so add a new heuristic to avoid roaming to a BSS if it is
either outdated or bad.

Doing this moves all scan data processing into wnm_scan_process() and
removes duplicated functionality for scan result processing in scan.c.
