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.

bbee36e316 Allow RADIUS server address to be replaced
The new hostapd parameters auth_server_addr_replace and
acct_server_addr_replace can now be used to replace the configured IP
address instead of adding a new RADIUS server. This is mainly useful for
testing purposes where the address can be changed over control interface
during AP operation.

8412dd52d1 tests: Increase default VM memory from 128M to 192M
It looks like the 128M default memory size for the hwsim test setup was
not large enough to cover all the needs anymore. Some of the test cases
using tshark could hit OOM with that size. Increase the default
allocation to 192M to avoid this type of issues.

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.

71d77adb6d Update current BSS level when signal change event occurs
When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this
change but the new RSSI value is not stored. In consequence, when
roaming candidates are evaluated, the RSSI value of the current BSS used
to compare is an old one obtained during the last scan rather than the
new one given by the signal change event. This leads sometimes to bad
decision when selecting a new BSS for roaming.

This patch solves the issue by updating the current BSS level when
receiving a signal change event in order to have a very up-to-date
current signal value when choosing an new BSS.
