Christoph Paasch 1759389e8a xfrm4: Remove duplicate semicolon
3328715e6c (xfrm4: Add IPsec protocol multiplexer) adds a
duplicate semicolon after the return-statement.

Although it has no negative impact, the second semicolon should be
removed.

Steffen Klassert 61622cc6f2 xfrm4: Properly handle unsupported protocols
We don't catch the case if an unsupported protocol is submitted
to the xfrm4 protocol handlers, this can lead to NULL pointer
dereferences. Fix this by adding the appropriate checks.

Steffen Klassert 2f32b51b60 xfrm: Introduce xfrm_input_afinfo to access the the callbacks properly
IPv6 can be build as a module, so we need mechanism to access
the address family dependent callback functions properly.
Therefore we introduce xfrm_input_afinfo, similar to that
what we have for the address family dependent part of
policies and states.

Steffen Klassert 70be6c91c8 xfrm: Add xfrm_tunnel_skb_cb to the skb common buffer
IPsec vti_rcv needs to remind the tunnel pointer to
check it later at the vti_rcv_cb callback. So add
this pointer to the IPsec common buffer, initialize
it and check it to avoid transport state matching of
a tunneled packet.

Steffen Klassert 3328715e6c xfrm4: Add IPsec protocol multiplexer
This patch add an IPsec protocol multiplexer. With this
it is possible to add alternative protocol handlers as
needed for IPsec virtual tunnel interfaces.
