The bits not written to are marked tainted by valgrind, don't print
them in the debug messages. Also use more specific printf-specifiers
for other values.
There was a race condition between install() and uninstall()
where one thread was in the process of installing a trap
entry, and had destroyed the child_sa, while the other
thread was uninstalling the same trap entry and ended up
trying to destroy the already destroyed child_sa, resulting
in a segmentation fault in the destroy_entry() function.
The uninstall() function needs to wait until all the threads
are done with the installing before proceeding to uninstall
a trap entry.

This can be the case for IKEv1 since 419ae9a20a ("ikev1: Default remote
identity to %any for PSK lookup if not configured").

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.
Some users requests something like that to use different server IPs.
Interestingly, it's actually also possible to configure multiple
hostnames/IPs, separated by commas, as server address in the profile, which
are then tried one after another.
It's also useful when testing stuff to quickly compare the behavior with
some setting changed between two otherwise identical profiles.
A temporary DROP policy is added to avoid traffic leak
while the SA is being updated. It is added with
manual_prio set but when the temporary policy is removed
it is removed with manual_prio parameter set to 0.
The call to del_policies_outbound does not match the original
policy and we end up with an ever increasing refcount.
If we try to manually remove the policy, it is not removed
due to the positive refcount. Then new SA requests fail with
"unable to install policy out for reqid 1618,
the same policy for reqid 1528 exists"

Instead, create a socket when necessary. Apparently, it can prevent
the agent from getting terminated (e.g. during system shutdown) if e.g.
charon-nm is still running with an open connection to the agent.
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.

Up to now it was assumed that the RSA public key exponent is equal to 2^16+1.
Although this is probably true in most if not all cases, it is not correct
according to the TPM 2.0 specification.
This patch fixes that by reading the exponent from the structure returned
by TPM2_ReadPublic.
Closesstrongswan/strongswan#121.
