Stefano Brivio e7cc082455 udp: Support for error handlers of tunnels with arbitrary destination port ... ICMP error handling is currently not possible for UDP tunnels not employing a receiving socket with local destination port matching the remote one, because we have no way to look them up. Add an err_handler tunnel encapsulation operation that can be exported by tunnels in order to pass the error to the protocol implementing the encapsulation. We can't easily use a lookup function as we did for VXLAN and GENEVE, as protocol error handlers, which would be in turn called by implementations of this new operation, handle the errors themselves, together with the tunnel lookup. Without a socket, we can't be sure which encapsulation error handler is the appropriate one: encapsulation handlers (the ones for FoU and GUE introduced in the next patch, e.g.) will need to check the new error codes returned by protocol handlers to figure out if errors match the given encapsulation, and, in turn, report this error back, so that we can try all of them in __udp{4,6}_lib_err_encap_no_sk() until we have a match. v2: - Name all arguments in err_handler prototypes (David Miller) Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.
