Martin Willi ca4a14ae83 kernel-pfkey: when installing a route for a virtual IP, use its interface 
When installing a route over a tun device for a virtual IP, the route must
be set over the tun, not the IKE interface.

Martin Willi d4260c5f7f kernel-pfkey: install route along with input, not forward policies 
As forwarding policies are not available on all systems (OS X), using the
forward policy to attach the route is a bad pick. Using input policies allows
OS X to install routes.

the one actually used with the current source address.

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 9896b6bd58 Don't compare ports when comparing cached routes. 
At least src_ip has a port set sometimes.

Tobias Brunner 051226d5c0 Silently install route again, even if it did not change. 
Address/interface changes can cause the route to disappear. Afterwards
the route might look the same but that does not mean it is still installed.

Tobias Brunner d7a59f1976 Install fallback drop policies to avoid transmitting unencrypted packets. 
During the update of a CHILD_SA (e.g. caused by MOBIKE) the old policy
is first uninstalled and then the new one is installed.  In the short
time in between, where no policy is available in the kernel, unencrypted
packets could have been transmitted.

Tobias Brunner fbedc6a45b Remove policies in kernel interfaces based on their priority. 
This allows to unroute a connection while the same connection is
currently established.  In this case both CHILD_SAs share the same
reqid but the installed policies have different priorities.

Tobias Brunner f3bb1bd039 Fixed common misspellings. 
Mostly found by 'codespell'.

Tobias Brunner 3ee8fed445 Cache the most recent reqid in the PF_KEY kernel interface. 
This makes the PF_KEY kernel interface behave the same as the Netlink
kernel interface.

Tobias Brunner e6f42b0721 Include the destination net in the policy priority calculation. 
The resulting priorities are as follows:

    IPv6               IPv4
    routed   normal    routed   normal
max 4096(+3) 2048(+3)  4096(+3) 2048(+3)
min 3072     1024      3840     1792

Where min is for a policy between two single hosts and max is
for /0 on both ends (lower priorities are preferred by the kernel).
(+3) applies for cases where no protocol and no ports are defined.

Tobias Brunner b8bf01ddee Do not install routes for pluto. 
There are some incompatibilities with e.g. passthrough policies.
Pluto installs required source routes via updown script.

Tobias Brunner bd7a2f3bfc Added an option to specify the type of a policy to kernel_ipsec.add_policy. 
This will later allow us to support pluto's passthrough and drop
policies in charon.
