The roam D-Bus and ROAM control itnerface commands flip the reassociate
bit before calling wpa_supplicant_connect(). wpa_supplicant connect
eventually aborts ongoing scans (if any), which causes scan results to
be reported. Since the reassociate bit is set, this will trigger a
connection attempt based on the aborted scan's scan results and cancel
the initial connetion request. This often causes wpa_supplicant to
reassociate to the same AP it is currently associated to instead of the
explicitly requested roaming target.
Add a roam_in_progress flag to indicate that we're currently attempting
to roam via an explicitly request to a specific BSS so that we don't
initiate another connection attempt based on the possibly received scan
results from a scan that was in progress at the time the roam command
was received.

These frames are used for verifying that a specific SA and protected

For an autonomous P2P group on the 5 GHz band, a channel was picked only
from the operating class 115 which is not available in the EU region
anymore. As a result, an autonomous group creation would always fail in

There are more possible available channels for the 5 GHz currently.
Especially in the EU region, the operating class 115 channels are no

It was not easily possible to separate configuration of an interface and
credentials when using the configuration file instead of the control
interface or D-Bus interface for setting up the network profiles. This
makes it hard to distribute configuration across a set of nodes which
use wpa_supplicant without also having to store credentials in the same
file. While this can be solved via scripting, having a native way to
achieve this would be preferable.
Turns out there already is a framework to have external password
storages. It only had a single "test" backend though, which is kind of
an in-memory store which gets initialized with all passwords up front
and is mainly for testing purposes. This isn't really suitable for the
above use case: the backend cannot be initialized as part of the central
configuration given that it needs the credentials, and we want to avoid
scripting.
This commit thus extends the infrastructure to implement a new backend,
which instead uses a simple configuration file containing key-value
pairs. The file follows the format which wpa_supplicant.conf(5) uses:
empty lines and comments are ignored, while passwords can be specified
with simple `password-name=password-value` assignments.
With this new backend, splitting up credentials and configuration
becomes trivial:
# /etc/wpa_supplicant/wpa_supplicant.conf
ext_password_backend=file:/etc/wpa_supplicant/psk.conf
network={
ssid="foobar"
psk=ext:foobar
}
# /etc/wpa_supplicant/psk.conf
foobar=ecdabff9c80632ec6fcffc4a8875e95d45cf93376d3b99da6881298853dc686b
Alternative approaches would be to support including other configuration
files in the main configuration, such that common configuration and
network declarations including credentials are split up into separate
files. But the implementation would probably have been more complex
compared to reusing the already-existing framework for external password
backends.

There's a chance that prior to config reload being requested a scan work
was started. As such forcing wpa_supplicant to WPA_DISCONNECTED was
removing any hints that the actual driver is busy with work. That led to
wpa_supplicant reporting "Failed to initialize AP scan" over and over
again for a few seconds (depending on driver/capabilities) until the
untracked scan finished.
Cancelling a scan isn't really a solution because there's a bunch of
scanning state bits sprinkled across wpa_supplicant structure and they
get updated as driver events actually flow in in async manner.
As far as I can tell this is only preventing unnecessary warning
messages. This doesn't seem like it was crippling any logic per se.

The chirp scan could override the scan_res_handler. This could lead to
wpa_supplicant getting stuck in a scanning state while not scanning at
all until forced to, e.g., via an explicit SCAN control command.
The condition for trigerring this problem in my testing was when
(interface_count % 3) == 2. This introduced a two second delay before
actual scan was triggered after starting the wpa_supplicant instance up.
If DPP chirping was requested fast enough, in between the queueing and
triggering, it would punt the scan request, never to be resumed again.
Chirp scan handler wouldn't resume it leaving wpa_supplicant
inadvertently idle.

If there is a disconnect command from wpa_supplicant immediately after
the driver sends a connection event to userspace but before that event
is received and processed by wpa_supplicant, wpa_supplicant processes
the disconnect command and a self-generated disconnected event first
followed by the connected event received from the driver. As a result
wpa_supplicant moves to the WPA_COMPLETED state. Whereas the driver
processes the disconnect command received from wpa_supplicant after it
sends the connected event and moves to the disconnected state. Due to
this race between the disconnect command from wpa_supplicant and the
connected event from the driver, wpa_supplicant is moving to the
connected state though the driver is moving to the disconnected state
which results in abnormal functionality.

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.

poor connection quality, etc.

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.
