Add initial_freq_list to wpa_supplicant configuration. This option
allows wpa_supplicant to scan a smaller list of frequencies when it
starts. This in turn allows for a faster connection to an already known
network. This limit applies only for the initial scan operation and does
not restrict other channels from being used in consecutive scans.
Tests have shown this to reduce the amount of time for connecting to a
network from roughly 3 seconds to roughly 0.1 second.

The hostapd DFS code deinitializes and initializes the AP interface, if
a clean channel switch is not possible. In this case the AP code paths
would deinit the driver, for example nl80211, without wpa_supplicant
code paths getting notice of this.
Therefore add callbacks for wpa_supplicant mesh methods, which are
called on init/deinit of the AP BSS. These callbacks are then used to

Mesh join function is the last function to be called during mesh join
process, but it's been called a bit earlier than it's supposed to be, so
that some mesh parameter values such as VHT capabilities were not
applied correct when mesh join is in process. Moreover, the current
design of mesh join that is called directly after mesh initialization
isn't suitable for DFS channels to use, since mesh join process should
be paused until DFS CAC is done and resumed after it's done.
The callback will be called by hostapd_setup_interface_complete_sync().

If the maximum operating channel width for AP/P2P GO is not specified,
it is auto-selected during configuration. While selecting the channel
width, if VHT is supported and 160 MHz channels are available, 160 MHz
channel width is preferred to 80 MHz.
During the selection of the channel width, the corresponding driver
capabilities were not checked. As a result, the AP/P2P GO configuration
was set to use the available 160 MHz channels even if the driver did not
have capability to support the 160 MHz channel width causing failure to
start the AP/P2P GO.

If the stored configurations for an SSID have changed, we can no longer
trust the current blacklist state of that SSID, since the updated
configs could change the behavior of the network. E.g., the BSS could be
blacklisted due to a bad password, and the config could be updated to
store the correct password. In this case, keeping the BSS in the
blacklist will prevent the user from connecting to the BSS after the
correct password has been updated.
Add the value was_changed_recently to the wpa_ssid struct. Update this
value every time a config is changed through wpa_set_config(). Check
this value in wpa_blacklist_get() to clear the blacklist whenever the
configs of current_ssid have changed.
This solution was chosen over simply clearing the blacklist whenever
configs change because the user should be able to change configs on an
inactive SSID without affecting the blacklist for the currently active
SSID. This way, the blacklist won't be cleared until the user attempts
to connect to the inactive network again. Furthermore, the blacklist is
stored per-BSSID while configs are stored per-SSID, so we don't have the
option to just clear out certain blacklist entries that would be
affected by the configs.
Finally, the function wpa_supplicant_reload_configuration() causes the
configs to be reloaded from scratch, so after a call to this function
all bets are off as to the relevance of our current blacklist state.
Thus, we clear the entire blacklist within this function.

This change adds the function wpa_blacklist_update(), which goes through
all blacklist entries and deletes them if their blacklist expired over
an hour ago. The purpose of this is to remove stale entries from the
blacklist which likely do not reflect the current condition of device's
network surroundings. This function is called whenever the blacklist is
polled, meaning that the caller always gets an up-to-date reflection of
the blacklist.
Another solution to clearing the blacklist that was considered was
to slowly reduce the counts of blacklist entries over time, and delete
them if the counts dropped below 0. We decided to go with the current
solution instead because an AP's "problematic" status is really a binary
thing: either the AP is no longer problematic, or it's still causing us
problems. So if we see any more problems within a reasonable amount of
time, it makes sense to just keep the blacklist where it was since the
AP is likely still undergoing the same issue. If we go a significant
amount of time (semi-arbitrarily chosen as 1 hour) without any issues
with an AP, it's reasonable to behave as if the AP is no longer
undergoing the same issue. If we see more problems at a later time, we
can start the blacklisting process fresh again, treating this as a brand
new issue.

wpa_supplicant keeps a blacklist of BSSs in order to prevent repeated
associations to problematic APs*. Currently, this blacklist is
completely cleared whenever we successfully connect to any AP. This
causes problematic behavior when in the presence of both a bad AP and
a good AP. The device can repeatedly attempt to roam to the bad AP
because it is clearing the blacklist every time it connects to the good
AP. This results in the connection constantly ping-ponging between the
APs, leaving the user stuck without connection.
Instead of clearing the blacklist, implement timeout functionality which
allows association attempts to blacklisted APs after some time has
passed. Each time a BSS would be added to the blacklist, increase the
duration of this timeout exponentially, up to a cap of 1800 seconds.
This means that the device will no longer be able to immediately attempt
to roam back to a bad AP whenever it successfully connects to any other
AP.
Other details:
The algorithm for building up the blacklist count and timeout duration
on a given AP has been designed to be minimally obtrusive. Starting with
a fresh blacklist, the device may attempt to connect to a problematic AP
no more than 6 times in any ~45 minute period. Once an AP has reached a
blacklist count >= 6, the device may attempt to connect to it no more
than once every 30 minutes. The goal of these limits is to find an
ideal balance between minimizing connection attempts to bad APs while
still trying them out occasionally to see if the problems have stopped.
The only exception to the above limits is that the blacklist is still
completely cleared whenever there are no APs available in a scan. This
means that if all nearby APs have been blacklisted, all APs will be
completely exonerated regardless of their blacklist counts or how close
their blacklist entries are to expiring. When all nearby APs have been
blacklisted we know that every nearby AP is in some way problematic.
Once we know that every AP is causing problems, it doesn't really make
sense to sort them beyond that because the blacklist count and timeout
duration don't necessarily reflect the degree to which an AP is
problematic (i.e. they can be manipulated by external factors such as
the user physically moving around). Instead, its best to restart the
blacklist and let the normal roaming algorithm take over to maximize
our chance of getting the best possible connection quality.
As stated above, the time-based blacklisting algorithm is designed to
be minimally obtrusive to user experience, so occasionally restarting
the process is not too impactful on the user.

Within wpas_connection_failed(), the 'count' value of wpa_blacklist is
erroneously used as a tally of the number times the device has failed
to associate to a given BSSID without making a successful connection.
This is not accurate because there are a variety of ways a BSS can be
added to the blacklist beyond failed association such as interference
or deauthentication. This 'count' is lost whenever the blacklist is
cleared, so the wpa_supplicant stores an additional value
'extra_blacklist_count' which helps persist the 'count' through clears.
These count values are used to determine how long to wait to rescan
after a failed connection attempt.
While this logic was already slightly wrong, it would have been
completely broken by the upcoming change which adds time-based
blacklisting functionality. With the upcoming change, 'count' values
are not cleared on association, and thus do not necessarily even
approximate the "consecutive connection failures" which they were being
used for.
This change seeks to remove this unnecessary overloading of the
blacklist 'count' by directly tracking consecutive connection failures
within the wpa_supplicant struct, independent of the blacklist. This new
'consecutive_conn_failures' is iterated with every connection failure
and cleared when any successful connection is made. This change also
removes the now unused 'extra_blacklist_count' value.

operating classes 128 and 130 for P2P channel setup by handling this
jump in the channel number incrementation.

Previously this fallback from PFS enabled to disabled (and back to
enabled) was used only if the local network profile used key_mgmt=DPP,
i.e., did not enable another other AKM. That leaves out some valid cases
since the local network profile could actually enable both DPP and SAE.
Extend this check to accept cases DPP AKM is enabled and it was selected
for the connection even if there other enabled AKMs.

Previously wpabuf_head() of the buffer is passed to wpa_hexdump_buf()
instead of the wpabuf struct itself and it was causing wpa_supplicant to
crash. Fix this by using the correct pointer in the debug prints.

These were not really used anymore since the AP/Relay case did not set
msg_ctx or process_conf_obj in the global DPP context. Get the
appropriate pointers more directly from the more specific data
structures instead and remove these global values.

Extend hostapd support for DPP Controller to cover the DPP_CONTROLLER_*
cases that were previously implemented only in wpa_supplicant. This
allows hostapd/AP to be provisioned using DPP over TCP.

Share the same setup steps from the negotiated connection handover to
fix issues with NFC Tag write cases in AP mode. This addresses issues in
the AP mode DPP listen operation not actually receiving anything when
the write-a-tag code path was used.

The updated socket.poll() loop did not terminate properly in cases where
no response is available. Fix that to check for both False and None.

Add support to parse the (Re)Association Response frames to check if the
AP has accepted/declined the MSCS request in response to the
corresponding (Re)Association Request frame. AP indicates the result by
setting it in the optional MSCS Status subelement of MSCS Descriptor
element in (Re)Association Response frame.
This MSCS Status subelement is defined in the process of being added
into P802.11-REVmd/D4.0 (11-20-0516-17-000m-cr-mscs-and-cid4158).

This was supposed to wait for up to 3.0 seconds for the handover select,
but the incorrect loop terminated ended up limiting this to a single
iteration of 0.1 second wait. This was too fast for some cases like the
AP mode operation where it may take significant time to enable the radio
for listening to DPP authentication messages.
Fix the loop to allow that full three second wait for the response to be
used. In addition, report the amount of time it takes to receive the
response.
