af835d75b7 FILS: Fix FILS connect failures after ERP key invalidation
If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.

Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again
for the consecutive connections.

9be19d0b9c SAE: Add support for using the optional Password Identifier
This extends the SAE implementation in both infrastructure and mesh BSS
cases to allow an optional Password Identifier to be used. This uses the
mechanism added in P802.11REVmd/D1.0. The Password Identifier is
configured in a wpa_supplicant network profile as a new string parameter
sae_password_id. In hostapd configuration, the existing sae_password
parameter has been extended to allow the password identifier (and also a
peer MAC address) to be set. In addition, multiple sae_password entries
can now be provided to hostapd to allow multiple per-peer and
per-identifier passwords to be set.

60a5737e8f FT: Clear SME FT data on disassoc
SME ft_used flag is sometimes not cleared on disassoc. For example,
after initial FT connection, ft_used is set while ft_ies stays NULL.
Later on, upon disassoc, sme_update_ft_ies() is not invoked and ft_used
is not cleared. Fix this by invoking sme_update_ft_ies() also in case
ft_used is set.

This is needed to fix an issue with drivers that use nl80211 Connect API
with FT and expect to the NL80211_AUTHTYPE_OPEN specified in the Connect
command for the initial mobility domain association.

06b1a10434 SAE: Fix default PMK configuration for PMKSA caching case
The RSN supplicant state machine PMK was set based on WPA PSK even for
the cases where SAE would be used. If the AP allows PMKSA caching to be
used with SAE, but does not indicate the selected PMKID explicitly in
EAPOL-Key msg 1/4, this could result in trying to use the PSK instead of
SAE PMK. Fix this by not setting the WPA-PSK as default PMK for SAE
network profiles and instead, configuring the PMK explicitly from the
found PMKSA cache entry.

3f56a2b746 Ignore pmf=1 default if driver does not support PMF
Connection with a PMF enabled AP will fail if we try to negotiate PMF
while the local driver does not support this. Since pmf=1 does not
require PMF for a successful connection, it can be ignored in such a
case to avoid connectivity issues with invalid configuration. This makes
it somewhat easier to allow upper layer programs to use pmf=1 default
regardless of driver capabilities.

a7f5271d52 Update pending connect radio work BSS pointer on scan update
It is possible for scan result processing or BSS entry removal to occur
while there is a pending connect or sme-connect radio work with a
previously selected BSS entry. The BSS pointer was previously verified
to be valid, i.e., still point to a BSS entry, at the time the actual
connection operation is started. However, that BSS entry could have
changed to point to another BSS if the old BSS entry was either removed
or reallocated and a new BSS entry was added at the same location in
memory. This could result in the connection attempt failing to configure
parameters properly due to different BSS information (e.g., different
BSSID).

Fix this by updated the pending connect radio work data on BSS entry
updates similarly to how the last_scan_res array was updated. If the
selected BSS entry is removed, this will still result in a failed
connection, but reallocated BSS entry is now followed properly and used
when the connection work starts.

d0df643735 wpa_supplicant: Call frequency conflict handling during auth
Previously, the frequency conflict was handled only during the
association flow. However, some drivers, e.g., mac80211 based
drivers, will fail an authentication request in case that there
are no available channels for use (as they might be used by
other interfaces), and thus the frequency conflict resolution
is never called.

Fix this by calling frequency conflict resolution during
authentication (SME-in-wpa_supplicant) as well.

In addition, get the shared radio frequency from the wpa_s context in
both the SME-in-driver and SME-in-wpa_supplicant cases and not from the
driver.

since EVENT_SCAN_RESULTS is discarded on a disabled interface.

Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.

To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
