ipvs: replace the SCTP state machine
Convert the SCTP state table, so that it is more readable. Change the states to be according to the diagram in RFC 2960 and add more states suitable for middle box. Still, such change in states adds incompatibility if systems in sync setup include this change and others do not include it. With this change we also have proper transitions in INPUT-ONLY mode (DR/TUN) where we see packets only from client. Now we should not switch to 10-second CLOSED state at a time when we should stay in ESTABLISHED state. The short names for states are because we have 16-char space in ipvsadm and 11-char limit for the connection list format. It is a sequence of the TCP implementation where the longest state name is ESTABLISHED. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>
