9feadba141 Remove unnecessary NULL check to make function more consistent
Static analyzers may warn about dereference before NULL check in
wpas_network_disabled() due to the new code added to check
wpa_s->p2p_mgmt. wpa_s cannot be NULL here, so remove the unneeded check
for it later in the function. (CID 106124)

1772d348ea P2P: Fix interface deinit for failed group interface initialization
wpa_supplicant_deinit_iface() ends up removing all P2P groups if the
removed interface is the parent interface. This is correct behavior in
general, but this resulted in issues in the new group interface
initialization error path since wpa_s->parent was not assigned before
hitting this check. Fix this by assigning wpa_s->parent as part of
wpa_supplicant_add_iface().

Commit 347c55e216 ('RADIUS client: Re-try
connection if socket is closed on retransmit') added a possibility of
executing RADIUS server failover change within
radius_client_retransmit() without taking into account that this
operation may end up freeing the pending message that is being
processed. This could result in use of freed memory. Avoid this by
checking whether any pending messages have been removed and if so, do
not try to retransmit the potentially freed message.

347c55e216 RADIUS client: Re-try connection if socket is closed on retransmit
Previously, send() was called with invalid fd = -1 in some error cases
for retransmission and this could even result in a loop of multiple such
attempts. This is obviously not going to work, so drop such attempts and
instead, try to reconnect a socket to the server if the current socket
is not valid.

In addition, initiate server failover immediately if the current socket
is not valid instead of waiting for a timeout.

94b39e5927 RADIUS client: Fix server connection recovery after initial failure
If the initial attempt at opening the socket connection to the RADIUS
server failed due to missing IP connectivity during startup, e.g., with
"connect[radius]: Network is unreachable", hostapd did not try to
reconnect when RADIUS messages were sent. Instead, it only reported "No
authentication server configured" even if the configuration did have a
server entry.

This was broken by commit 9ed4076673
('RADIUS client: Do not try to send message without socket') for the
initial case and the more recent fixes in RADIUS server failover cases
did not cover the initial failure case.

f51f54a007 nl80211: Resubscribe to nl80211 events on global nl_event socket
This allows wpa_supplicant to recover from some of the cases where
cfg80211 is unloaded and reloaded without restarting wpa_supplicant. The
netlink socket used for nl80211 events (global->nl_event) seemed to end
up in otherwise functionality state, but with all the event memberships
lost when cfg80211 gets reloaded.

There does not seem to be any clear way of determining when this has
happened, so it looks simplest to just try to re-subscribe to all the
events whenever an interface is re-enabled or added.

48ec6942cb Fix Linux packet socket workaround to not close the socket too easily
Commit e6dd8196e5 ('Work around Linux
packet socket regression') closed the workaround socket on the first
received EAPOL frame from the main packet socket. This can result in
closing the socket in cases where the kernel does not really work in the
expected way during the following initial association since
reauthentication/rekeying using EAPOL frames happens while operstate is
not dormant and as such, the frames can get delivered through the main
packet socket.

Fix this by closing the workaround socket only in case the first EAPOL
frame is received through the main packet socket. This case happens
while the interface is in dormant state and as such, is more likely to
show the more restricted case of kernel functionality.

In order to avoid processing the received EAPOL frames twice, verify a
checksum of the frame contents when receiving frames alternatively from
the main packet socket and the workaround socket.

0d2030ee20 Use estimated throughput to improve roaming selection
Previously, within-ESS roaming was skipped if the selected BSS did not
have a higher signal strength than the current BSS regardless of AP
capabilities. This could result in not moving to a BSS that would
provide higher throughput, e.g., due to larger channel bandwidth or
higher rates (HT/VHT MCS).

Use estimated throughput information from scan result processing to
allow within-ESS roaming if the selected BSS is likely to provide better
throughput even if the current BSS has larger RSSI.

a1b790eb9d Select AP based on estimated maximum throughput
This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.

In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
low enough to prevent higher MCS use.
