This makes wpa_supplicant behavior more consistent with FLUSH command to
clear all state. Previously, it was possible for an ongoing scan to be
aborted when the FLUSH command is issued and the scan results from that
aborted scan would still be processed and that would update the BSS
table which was supposed to cleared by the FLUSH command.
This could result in hwsim test case failures due to unexpected BSS
table entries being present after the FLUSH command.

The way the removal of duplicated (one per frequency) BSS entries in the
cfg80211 scan results were removed in driver_nl80211_scan.c
bss_info_handler() depended on having the full scan results available to
allow iteration through the other entries. This is problematic for the
goal of being able to optimize memory allocations for scan result
fetching in a manner that would not build the full result buffer in
memory.
Move this duplicate removal into bss.c since it has sufficient
information available for doing the same determination of which one of
two BSS entries is more current.

This gets rid of some dependencies on how extra octets at the end of the
struct sockaddr_un get "uninitialized" consistently by only using the
exact length of the address data from the recvfrom() call. This resolves

This commit enhances the existing implementation of abort scan to also
abort concurrent active vendor scans. This is achieved by passing the
the scan_cookie to the driver interface with the intention to abort
the specific scan request. This scan_cookie is returned from the driver
interface when the scan request is scheduled.
This scan_cookie is 0 if the scan is triggered through the upstream
cfg80211 interface. Thus, the scan_cookie is used to determine whether
to abort the cfg80211 or vendor scan request.
Also, the previous implementation of relying on scan_work/p2p_scan_work
for the active work to trigger the abort scan is enhanced to check for
the started state of either of these work operations. This should also
help to abort the concurrent active scan/p2p-scan operations.

cfg80211 rejects the scans issued with random MAC address if the STA is
in connected state. This resulted in failures when using MAC_RAND_SCAN
while connected (CTRL-EVENT-SCAN-FAILED ret=-95). Enable random MAC
address functionality only if the STA is not in connected state to avoid
this. The real MAC address of the STA is already revealed in the
association, so this is an acceptable fallback mechanism for now.

This enables configuring key_mgmt=NONE + mka_ckn + mka_cak.
This allows wpa_supplicant to work in a peer-to-peer mode, where peers
are authenticated by the pre-shared (CAK,CKN) pair. In this mode, peers
can act as key server to distribute keys for the MACsec instances.
This is what some MACsec switches support, and even without HW

Previously, the estimated throughput was used to enable roaming to a
better AP. However, this information was not used when considering a
roam to an AP that has better signal strength, but smaller estimated
throughput. This could result in allowing roaming from 5 GHz band to 2.4
GHz band in cases where 2.4 GHz band has significantly higher signal
strength, but still a lower throughput estimate.
Make this less likely to happen by increasing/reducing the minimum
required signal strength difference based on the estimated throughputs
of the current and selected AP. In addition, add more details about the
selection process to the debug log to make it easier to determine whaty
happened and why.

Previously, CONFIG_IEEE80211R enabled build that supports FT for both
station mode and AP mode. However, in most wpa_supplicant cases only
station mode FT is required and there is no need for AP mode FT.
Add support to differentiate between station mode FT and AP mode FT in
wpa_supplicant builds by adding CONFIG_IEEE80211R_AP that should be used
when AP mode FT support is required in addition to station mode FT. This
allows binary size to be reduced for builds that require only the
station side FT functionality.

This is specific to the macsec_qca driver. The core implementation
shouldn't care about this, and only deal with the complete secure
channel, and pass this down to the driver.
Drivers that have such limitations should take care of these in their
->create functions and throw an error.
Since the core MKA no longer saves the channel number, the macsec_qca
driver must be able to recover it. Add a map (which is just an array
since it's quite short) to match SCIs to channel numbers, and lookup
functions that will be called in every place where functions would get
the channel from the core code. Getting an available channel should be
part of channel creation, instead of being a preparation step.

When starting ASP provisioning with connection capability set to NEW,
don't create the pending P2P interface as a GO interface because
Go negotiation will determine which side will be the GO and it is
possible that eventually this interface will become the client.
In this case, when the P2P client is started it will start scanning
and do other station specific operations while the interface type
is AP.
Instead, use type WPA_IF_P2P_GROUP when creating the interface which
means the interface type will be determined later.
