4b96fafcd8 D-Bus: Share 'remove all networks' with CLI
The D-Bus implementation of RemoveAllNetworks differs wildly from the
CLI implementation. Let's share the implementations.

This resolves use-after-free bugs I noticed, where we continue to use
the 'wpa_s->current_ssid' wpa_ssid object after freeing it, because we
didn't bother to disconnect from (and set to NULL) current_ssid before
freeing it.

cff545720e wpa_supplicant: Clear blacklist when SSID configs change
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.

d530110028 wpa_supplicant: Implement time-based blacklisting
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.

*problematic AP: rejects new clients, frequently de-auths clients, very
poor connection quality, etc.

2fd35d9857 wpa_supplicant: Track consecutive connection failures
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.

key management suite, use FILS authentication algorithm for connection
even if ERP keys are not available. This scenario may happen when
applications using wpa_supplicant cache persistently only PMKSA but not

The previous implementation correctly handles SME-in-wpa_supplicant
cases. However, SME-in-driver cases, complete FILS authentication
without PMKSA caching is performed.

Fix SME-in-driver behavior by setting authentication algorithm to
WPA_AUTH_ALG_FILS when connecting to a FILS AP using PMKSA caching.

5058f771d9 DPP2: Allow station to require or not allow PFS
The new wpa_supplicant network profile parameter dpp_pfs can be used to
specify how PFS is applied to associations. The default behavior
(dpp_pfs=0) remains same as it was previously, i.e., try to use PFS if
the AP supports it. PFS use can now be required (dpp_pfs=1) or disabled
(dpp_pfs=2).

This is also working around an interoperability issue of DPP R2 STA with
certain hostapd builds that included both OWE and DPP functionality.
That issue was introduced by commit 09368515d1 ("OWE: Process
Diffie-Hellman Parameter element in AP mode") and removed by commit
16a4e931f0 ("OWE: Allow Diffie-Hellman Parameter element to be
included with DPP"). hostapd builds between those two commits would
reject DPP association attempt with PFS. The new wpa_supplicant default
(dpp_pfs=0) behavior is to automatically try to connect again with PFS
disabled if that happens.

SM Power Save was described in somewhat unclear manner in IEEE Std

SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.

A driver supports FT if it either supports SME or the
NL80211_CMD_UPDATE_FT_IES command. When selecting AKM suites,
wpa_supplicant currently doesn't take into account whether or not either
of those conditions are met. This can cause association failures, e.g.,
when an AP supports both WPA-EAP and FT-EAP but the driver doesn't
support FT (wpa_supplicant will decide to do FT-EAP since it is unaware
the driver doesn't support it). This change allows an FT suite to be
selected only when the driver also supports FT.

641d79f165 SAE: Special test mode sae_pwe=3 for looping with password identifier
The new sae_pwe=3 mode can be used to test non-compliant behavior with
SAE Password Identifiers. This can be used to force use of
hunting-and-pecking loop for PWE derivation when Password Identifier is
used. This is not allowed by the standard and as such, this
functionality is aimed at compliance testing.
