An EAPOL frame may be pending when wpa_supplicant requests to
deauthenticate. At this stage the EAP SM cache is already cleaned by
calling eapol_sm_invalidate_cached_session(). Since at this stage the
wpa_supplicant's state is still set to associated, the EAPOL frame is
processed and results in a crash due to NULL dereference.
This wasn't seen previously as nl80211 wouldn't process the
NL80211_CMD_CONTROL_PORT_FRAME, since wpa_driver_nl80211_mlme() would
set the valid_handler to NULL. This behavior was changed in commit
ab89291928 exposing this race.
Fix it by ignoring EAPOL frames while the deauthentication is in
progress.

Add the address family when manually constructing IPv4 addresses in
eapol_test on Windows. Otherwise other functions, like hostapd_ip_txt()
in src/utils/ip_addr.c, that rely on addr->af being set fail miserably.
The non-Windows option uses hostapd_parse_ip_addr() which does this as
part of the helper function.

The nl_connect is initialized with the process_bss_event() handler.
However, it is used several times with the default valid handler. As a
result, if a message that is only valid for process_bss_event() is
received while the default handler is used, it will be dropped.
This has been observed in a case where during the 4-way handshake, a
Beacon frame is received on the AP side, which triggers a beacon update,
just before receiving the next EAPOL. When send_and_recv_msgs_owner() is
called for sending the NL80211_CMD_SET_BEACON command, the
NL80211_CMD_CONTROL_PORT_FRAME event is already pending. As a result, it
is received with the default handler, which drops it. Since the EAPOL
frame is dropped, the connection attempt fails.
Fix it by using the process_bss_event() handler when the nl_connect
handler is used.

While it does not look like the stale pointer could have been

When an interface is disabled, e.g. due to radar detected,
hapd->time_adv is freed by hostapd_free_hapd_data(), but later
used by ieee802_11_build_ap_params() calling hostapd_eid_time_adv().
Thus hapd->time_adv needs to be cleared as well.

The roam D-Bus and ROAM control itnerface commands flip the reassociate
bit before calling wpa_supplicant_connect(). wpa_supplicant connect
eventually aborts ongoing scans (if any), which causes scan results to
be reported. Since the reassociate bit is set, this will trigger a
connection attempt based on the aborted scan's scan results and cancel
the initial connetion request. This often causes wpa_supplicant to
reassociate to the same AP it is currently associated to instead of the
explicitly requested roaming target.
Add a roam_in_progress flag to indicate that we're currently attempting
to roam via an explicitly request to a specific BSS so that we don't
initiate another connection attempt based on the possibly received scan
results from a scan that was in progress at the time the roam command
was received.

os.stat(path) failure is an ambigious indication of the control
interface "path" type (UDP hostname vs. UNIX domain socket path). The
path may be a valid UNIX domain socket path, but that socket could have
been removed just before reaching here. At least the hwsim test case
concurrent_p2pcli managed to hit the "connect exception" print below
from UDP handling even when using a UNIX domain socket.
Work around incorrect determination of control interface socket type by
assuming anything starting with '/' is a UNIX domain socket and not a
hostname.
