Martin Willi ec1b4e6638 Merge branch 'vip-shunts'

assigned, and installs a proper source route to actually use the physical
address for bypassed destinations.

Martin Willi a36b49f3cb Merge branch 'opaque-ports'
Adds a %opaque port option and support for port ranges in left/rightprotoport.
Currently not supported by any of our kernel backends.

Martin Willi a2fd08dd26 Install a route for shunt policies
If we install a virtual IP, its source route would render the shunt policy
useless, as locally generated traffic wouldn't match. Having a route for each
shunt policy with higher priority chooses the correct source address for
bypassed destinations.

Martin Willi 544c2e3d7b kernel-netlinks get_interface() considers virtual IPs, too
When using load-tester, we can install tunnel outer addresses on
demand. As these are installed as "virtual", we have to consider
virtual IPs in the get_interface() lookup to install "real" virtual
IPs to these dynamic external addresses.

Tobias Brunner cbd52e7ddc Limit recursion when searching for source addresses
This could be required if e.g. two default routes list gateways but the
corresponding outbound interfaces do not have any IP addresses on them.

Tobias Brunner dad6d904ee Use source address in get_nexthop() call
Otherwise the nexthop returned might belong to a different route than
the one actually used with the current source address.

Tobias Brunner 662534657f Source address lookup refactored
Routes matching the destination are now first parsed and sorted by network
prefix length.  This list is then used to search for the best route with
a matching preferred source address (if one is specified).  This makes sure
we really check all routes for that address.

Tobias Brunner 9d6b02d6c1 Try to find preferred source on interface if returned source does not match 2012-09-21 18:16:25 +02:00
Tobias Brunner da6d86dd94 Try to keep the given source address when looking up routes
This allows to pin the local end of an IKE_SA to an address that is not the
physical address of an interface.  Without this patch the local address would
change to the physical address when roam events occur.

Tobias Brunner 31a0e24b0f Increased log level when listing interfaces and IP addresses during startup

already lists the available addresses anyway.

Tobias Brunner 26d77eb3e6 Centralized thread cancellation in processor_t
This ensures that no threads are active when plugins and the rest of the
daemon are unloaded.

callback_job_t was simplified a lot in the process as its main
functionality is now contained in processor_t.  The parent-child
relationships were abandoned as these were only needed to simplify job
cancellation.

Tobias Brunner 7beb31aae4 Fixed IPv6 source address lookup
Because Linux kernels prior to 3.0 do not support RTA_PREFSRC for
IPv6 routes we didn't use NLM_F_DUMP to get all routes.
Still routes installed with policies are installed also for IPv6.
So since only one route is returned without DUMP, and we ignore
all routes from our own routing table, no source address was found
during roaming if DST of the installed route included the IKE peer.

With newer kernels we can now use DUMP as we did for IPv4 already,
for older kernels we do so if our own routes are installed in a
separate routing table, otherwise we still use GET.
