If an implicit TDLS set up request is obtained on an existing link or an
to be established link, the previous link was not removed. This commit
disables the existing link on a new set up request. Also,
wpa_tdls_reneg() function was invoking wpa_tdls_start() on an already
existing peer for the case of internal setup, which is incorrect. Thus
the invocation of wpa_tdls_start() is removed in wpa_tdls_reneg() and
also this function is renamed to wps_tdls_remove() as it does not
renegotiation rather shall remove the link (if any) for the case of

Commit 50178335bf introduced a regression

If scan results are available when we perform a SelectNetwork, use
them to make an associate decision. This can save an entire scan
interval-worth of time in situations where something external to
wpa_supplicant (like a connection manager) has just previously
requested a scan before calling SelectNetwork.

When the scan interval is changed the new interval is effective
after the old interval timer fires off one last time. This can cause
an unacceptable long delay when updating the interval.
Change this behaviour to use MIN(left of old interval, new interval)
for the scan interval following the interval change.

If the driver rejected any of the offchannel Action frame TX requests,
the previous implementation terminated ANQP fetch process. While the
driver should not really reject the request normally, it is possible
that a request gets rejected for some reason. Allow the fetch process to
continue with the next AP in such case to avoid breaking networking
selection. This could result, e.g., in auto_interworking=1 process
failing to connect if any the driver rejects requests to any of the APs
in the scan result even if some other APs provided suitable information.

This was used to select between "(auth)" and "(reauth)" in
CTRL-EVENT-CONNECTED events. However, the variable was not cleared

proper clearing added. As such, it is cleaner to just get rid of this

Commit 1ff733383f added a mechanism to
work around issues due to association events and EAPOL RX events being
getting reordered. However, this applied only for the case where
wpa_supplicant is not in associated state. The same issue can happen in
roaming case with drivers that perform BSS selection internally (or in
firmware). Handle that case similarly by delaying received EAPOL frame
processing if the source address of the EAPOL frame does not match the
current BSSID.
Since wired IEEE 802.1X do not have BSSID, make this additional
workaround conditional on BSSID match having been observed during the
previous association.
This fixes issues where the initial EAPOL frame after reassociation was
either dropped (e.g., due to replay counter not increasing) or replied
to with incorrect destination address (the BSSID of the old AP). This
can result in significantly more robust roaming behavior with drivers
that do not use wpa_supplicant for BSS selection.
