ab89291928 nl80211: Use process_bss_event() for the nl_connect handler
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.

2da3105ac1 Fix use after free with hapd->time_adv on interface restart
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.

5ac977758d Reject authentication start during explicit roam requests
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.

ed14b29f38 wpaspy: Do not mark not-existing UNIX domain socket as UDP
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.

57fec19dab Use more consistent iface->conf checks
Commit f1df4fbfc7 ("mesh: Use setup completion callback to complete
mesh join") added a check for iface->conf being NULL into a debug print.
However, it is not clear how that could be NULL here. In any case,
setup_interface() could end up dereferencing iface->conf in the call to
hostapd_validate_bssid_configuration(), so better be consistent with the
checks and not get warnings from static analyzers regardless of whether
this can happen in practice.

a826ff2d95 Ignore group-addressed SA Query frames
These frames are used for verifying that a specific SA and protected
link is in functional state between two devices. The IEEE 802.11
standard defines only a case that uses individual MAC address as the
destination. While there is no explicit rule on the receiver to ignore
other cases, it seems safer to make sure group-addressed frames do not
end up resulting in undesired behavior. As such, drop such frames
instead of interpreting them as valid SA Query Request/Response.

d314213f6c P2P: Pick a 5 GHz channel from more possible channels
For an autonomous P2P group on the 5 GHz band, a channel was picked only
from the operating class 115 which is not available in the EU region
anymore. As a result, an autonomous group creation would always fail in
this generic 5 GHz channel case.

There are more possible available channels for the 5 GHz currently.
Especially in the EU region, the operating class 115 channels are no
longer available, but SRD channels (the operating class 124) are
available. Allow them to be used here if they are marked as allowed for
P2P GO use.

In addition, iterate through all the potential options instead of just
checking the first randomly picked channel. Start this iteration from
random position to maintain some randomness in this process.
