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

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.

wpa_supplicant is started from /init.*.rc on Android and that seems

applications in the wifi group. Fix this by adding group access even

In most cases, this issue was not hit since the control interface
directory is normally created by that same init.*.rc file with suitable
mode and wpa_supplicant is killed in the way that does not allow it to
remove the file. However, if wpa_supplicant is allowed stop cleanly, it

The GO may be in sleep when we send a PD Request frame to indicate that
we are about to join a running group. Previously, this frame was not
retried more than normal low level retries. This can result in the GO
not getting the frame especially in cases where concurrent multi-channel
operations or aggressive sleep schedule is used since most drivers do
not yet synchronize with the GO's NoA before association.
Increase the likelihood of the GO receiving the PD Request frame by
retransmitting it similarly to the PD-for-GO-Negotiation case. Start
the actual join operation only after these retries have failed to get
an acknowledgment from the GO to give the connection attempt a chance
to succeed if the driver implements better NoA synchronization for it.

There are a few instances where dbus handlers test the value
of errno to test whether strtoul completes successfully.
Since strtoul does not clear errno, and there's no strong
reason to suspect that errno is already clear, it is safer
to clear it right before calling strtoul. Also, any failure
in strtoul (setting errno non-zero) should be considered a
failure.
While testing using dbus-send, I found that a malformed

wpa_s->bssid is not set, so the code in these functions needs to figure
out the correct BSSID based on that field or wpa_s->pending_bssid. In
addition, it is possible that the BSSID is not even known at
wpa_supplicant at this point in time when using drivers that perform BSS
selection internally. In those cases, the disconnect command needs to be
sent to the driver without the BSSID.
This fixes issues where the driver (or cfg80211 in particular) may be

due to a ctrl_iface command) happens between connection request and
