The authentication flow in wpa_driver_nl80211_authenticate() can
result in a locally generated de-authentication, in which both
next_local_deauth and ignore_next_local_deauth are set.
However, in mlme_event_deauth_disassoc(), when ignore_deauth_event is
set, the flag is cleared, but the flow immediately returns leaving
ignore_next_local_deauth set, which can result in ignoring future deauth
event from the driver, leaving the wpa_supplicant in an inconsistent
state.
Fix this by clearing both flags in case that next_local_deauth is set.

This allows offloaded roaming to inform user space of the change in IP
subnet post roaming. The device may have roamed to a network which is in
a different subnet which will result in IP connectivity loss. Indicating
the change in subnet enables the user space to refresh the IP address or
to perform IP subnet validation if unknown status is indicated.
The driver indication is reported with a new event from wpa_supplicant
in the following format:
CTRL-EVENT-SUBNET-STATUS-UPDATE status=<0/1/2>
where
0 = unknown
1 = IP subnet unchanged (can continue to use the old IP address)
2 = IP subnet changed (need to get a new IP address)

It is possible for a driver to support sufficient number of channels to
hit the previous limit of 200 characters for the "nl80211: Scan included
frequencies:" debug message. Increase the maximum buffer length to 300
characters to allow more complete list of scanned frequencies to be
written into the debug log. This limit is more in line with the
MAX_REPORT_FREQS (50) limit.

Allow wpa_supplicant to use vendor scan (if supported by the driver)
together with the normal nl80211 scan and handling external scan events.
Since this results in possibility of concurrent scan operations, some of
the operations related to scan results need to check more carefully when
an event is relevant for a specific interface.

When device supports dual band operations with offloaded ACS, hw_mode
can now be set to any band (hw_mode=any) in order to allow ACS to select
the best channel from any band. After a channel is selected, the hw_mode
is updated for hostapd.

These are practically unreachable code since cfg80211 fills in the

drv->ctx always points to the first BSS and we should report event using
BSS related to the interface we got NL80211_CMD_NEW_STATION from.
This fixes STA association for drivers using NL80211_CMD_NEW_STATION and
multiple virtual interfaces.

Suppose there are two APs (AP1 & AP2) and user attempted to connect to
AP2 before the previous connection with AP1 could succeed. Now, if the
connection event comes for the older AP with failed status, we should
just ignore it as the wpa_supplicant state has moved to "ASSOCIATING"
with the new AP (AP2).
This is a similar to the case where a disconnection event is ignored for
a case where local disconnect request can cause the extra event to show
up during the next association process following that command.

Commit b41f26845a ('Add support for
offloading key management operations to the driver') used incorrect
variable for determining the KCK length. This does not get triggered in
normal use cases since KCK and KEK are always included and of the same
length (in currently supported key management cases). Anyway, this needs
to be fixed to check the correct attribute. (CID 74491)
