If the key type was specified but the ID was NULL or matched a subject, it
was possible that a certificate was returned that didn't actually match
the requested key type.

Also expose a method to call arbitrary commands, which allows calling not
yet wrapped commands. Exceptions are raised for all commands if the response
includes a negative "success" key (similar to how it's done in the Python
bindings).
Instead of assuming passwords are simply ASCII-encoded we now assume they are
provided UTF-8-encoded, which is quite likely nowadays. The UTF-8 byte
sequences are not validated, however, only valid code points are encoded
as UTF-16LE.
Fixes#3014.
This is mainly to see what's necessary to create them (in case we
integrate this into the daemon) and to experiment in our testing
environment without having to add a patched version of iproute2 (the
4.20.0 version in stretch-backports doesn't support XFRM interfaces
yet). The regular version of iproute2 can be used for other operations
with these interfaces (delete, up, addrs etc.).
This can be the case for IKEv1 since 419ae9a20a ("ikev1: Default remote
identity to %any for PSK lookup if not configured").
Closesstrongswan/strongswan#128.
This seems to avoid broadcast loops (i.e. processing and reinjecting the
same broadcast packet over and over again) as the packets we send via
AF_PACKET socket are neither marked nor from that interface.
In order to avoid that the kernel uses virtual tunnel IPs for traffic
over physical interfaces we previously deprecated the virtual IP. While
this is working it is not ideal. This patch adds address labels for
virtual IPs, which should force the kernel to avoid such addresses to
reach any destination unless there is an explicit route that uses it as
source address.
Using parse_time() directly actually overwrites the next member in the
child_cfg_create_t struct, which is start_action, which can cause
incorrect configs if inactivity is parsed after start_action.
Fixes#2954.
In 7b7290977 ("controller: Add option to force destruction of an IKE_SA")
the 'force' option was added as 3rd parameter to controller_t::terminate_ike.
However in vici's 'clear_start_action', the argument was incorrectly
placed as the 2nd parameter - constantly sending 0 (FALSE) as the
'unique_id' to terminate, rendering calls to 'handle_start_actions'
having undo=TRUE being unable to terminate the relevant conn.
For example, this is log of such a bogus 'unload-conn':
strongswan[498]: 13[CFG] vici client 96 requests: unload-conn
strongswan[498]: 13[CFG] closing IKE_SA #9
strongswan[498]: 13[IKE] unable to terminate IKE_SA: ID 0 not found
strongswan[498]: 09[CFG] vici client 96 disconnected
here, the unloaded conn's IKE id was 9, alas 'terminate_ike_execute'
reports failure to terminate "ID 0".
Fix by passing 'id, FALSE' arguments in the correct order.

This is particularly important for higher number of segments, but even
with small numbers there is a significant difference. For instance,
with 4 segments the fourth segment had no IPs assigned with the old
code, no matter how large the pool, because none of the eight bits used
for the segment check hashed/mapped to it.
Upcoming versions of FreeBSD will include an SADB_X_EXT_SA2 extension in
acquires that contains the reqid set on the matching policy. This allows
handling acquires even when no policies are installed (e.g. to work with
FreeBSD's implementation of VTI interfaces, which manage policies
themselves).
In case a subnet is moved from one interface to another the policies can
remain as is but the route has to change. This currently doesn't happen
automatically and there is no option to update the policy or route so
removing and reinstalling the policies is the only option.
Fixes#2820.
