This adds support for hostapd-as-RADIUS-authentication-server to request
subscription remediation for SIM-based credentials. The new hostapd.conf
parameter hs20_sim_provisioning_url is used to set the URL prefix for
the remediation server for SIM provisioning. The random
hotspot2dot0-mobile-identifier-hash value will be added to the end of
this URL prefix and the same value is stored in a new SQLite database
table sim_provisioning for the subscription server implementation to
use.

This extends the last_msk testing functionality in the RADIUS server to
work with EAP-TLS based on "cert-<serial_num>" form user names in the
database.
Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
CONFIG_RADIUS_TEST builds can now update the user SQLite database based
on authentication result from the last attempt. If the database has a
last_msk column, that will be set to the hexdump of the MSK whenever
authentication succeeds and to "FAIL" whenever authentication fails.
This can be used for testing purposes by having an external program
track authentication status per user.

This makes it more convenient to generate the URL in a way that
interoperates between different vendors. The AP is simply copying the
already constructed URL as-is from Access-Accept to WNM-Notification.
This means that the HO AAA can generate the URL in a manner that works
for the associated T&C Server without having to coordinate with each AP.

Allow hostapd RADIUS authentication server with SQLite EAP user DB to be

radius_server_session_free() does not remove the session from the
session list and these radius_server_get_new_session() error paths ended
up leaving a pointer to freed memory into the session list. This
resulted in the following operations failing due to use of freed memory.
Fix this by using radius_server_session_remove() which removes the entry
from the list in addition to calling radius_server_session_free().

It was possible to hit the previously used maximum of 100 active session
in some hwsim test case sequences like this one: eap_proto_pwd_errors
eap_proto_ikev2_errors eap_proto_sim_errors. This happened due to the
large number of RADIUS authentication iterations in short period of
time, i.e., within the 10 second timeout for expiring completed
sessions.
Increase RADIUS_MAX_SESSION from 100 to 1000 and also reduce the timeout
on expiring completed sessions from 10 to 5 seconds.

This tells to the server how long we have been trying to transmit the
message so that the actual time of the message generation can be
determined from receive time (ignoring network delays and only at
accuracy of one second).
For interim updates, only value 0 is used since there are no
retransmissions of the same message. For other accounting messages, the
initial attempt goes out with value 0 and the retransmissions, if
needed, show the number of seconds the message has been waiting in the
queue.
Update the Identifier and Authenticator in the messages whenever
updating the Acct-Delay-Time per RFC 2866, 4.1 requirements.

Instead of using the RADIUS client retransmission design with the old
RADIUS message contents for each retry, trigger a completely new interim
accounting update instance more quickly (using the same schedule as
RADIUS message retransmissions) to improve accounting updates in cases
where RADIUS message delivery fails. This allows the server to get up to
date information from the time the "retry" message was sent instead of
the old information from the time the first failed attempt was sent.

1. Add tagged VLAN to struct vlan_description
(compile limited number of tagged VLANs per description)
For k tagged VLANs, the first k entries in vlan_description.tagged
are used. They are sorted in ascending order. All other entries are
zero. This way os_memcmp() can find identical configurations.
2. Let tagged VLANs be parsed from RADIUS Access-Accept
3. Print VLAN %d+ with %d=untagged VID if tagged VLANs are set
4. Select an unused vlan_id > 4096 for new tagged VLAN configurations
5. Add EGRESS_VLAN RADIUS attribute parsing also for untagged VLANs
