Commit d28f4e44f1 optimized Interworking
network selection in a case where the operation is run while already
connected to the selected network by skipping the reconnection. However,
this did not take into account that a higher priority network may have
shown up in the new scan results.
Fix this by checking whether network selection based on the latest scan
results (the ones from the interworking_select operation) would result
in a network with higher priority being selected. If so, skip the
optimization and force normal network connection (which will select this
newly found higher priority network). This fixes cases where a
non-Hotspot 2.0 network with higher priority (e.g., home network) shows
up while connected to a Hotspot 2.0 network with lower priority.

This new priority parameter can be used to specify priorities between

Previously, any network block could be used to select the BSS to connect
to when processing scan results after Interworking network selection.
This can result in somewhat unexpected network selection in cases where
credential preferences indicated that a specific network was selected,
but another network ended up getting used for the connection. While the
older networks continue to be valid, add special processing for this
initial post-interworking-connect case to get more consistent network
selection to match with the Interworking network selection result.

If a BSS is disallowed temporarily with disallow_aps, the network
connection is going to fail. As such, there is not much point in
allowing Interworking network selection to try to connect with such BSS.
As such, do not consider disallowed networks for automatic network
selection and reject requests to connect to them through
INTERWORKING_CONNECT.

Do not add multiple network blocks for the same network from a single
credential. INTERWORKING_CONNECT used to generate a new network block
for each instance regardless of what network blocks have already been
configured. While this allows the connection to go through, it is not
efficient to leave behind potentially large number of network blocks
with the same contents (or worse, changed contents). Address this by
removing an older network block for the same credential before adding a
new one.

3GPP TS 24.232 Annex A.3 allows network operator to advertise only two
digits of MNC even if MNC has three digits. Allow such matches in

cannot be determined reliably. Remove the '-' separator from simulated
SIM/USIM cases to allow the new matching rules to work.

There may be cases where multiple BSS entries for a single BSSID are in
the table. This is mostly in automated test cases due to the AP
configuration changes, but something similar could potentially happen as
a corner case in more realistic networks, too, e.g., when an AP changes
its operating channel. Make network selection more robust by trying to
find the exact BSS entry instead of any BSS entry with a matching BSSID
when storing GAS/ANQP response.
Signed-hostap: Jouni Malinen <j@w1.fi>
Previously, the credential to use for a connection with a specific BSS
was picked arbitrary based on first found match of each matching
mechanism. While the credential priorities were used elsewhere, this did
not take into account that different mechanisms could find multiple
matching credentials. As such, the highest priority credential was not
always used in case more than one credential matched with the selected
BSS. Fix this by checking credential priorities again during connection
request.

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
in the scan result even if some other APs provided suitable information.
