inet: add TCP_NEW_SYN_RECV state
TCP_SYN_RECV state is currently used by fast open sockets. Initial TCP requests (the pseudo sockets created when a SYN is received) are not yet associated to a state. They are attached to their parent, and the parent is in TCP_LISTEN state. This commit adds TCP_NEW_SYN_RECV state, so that we can convert TCP stack to a different schem gradually. This state is not exported to user space. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
