conntrack: Allow protocol number zeroHEADmaster
/etc/protocols defines protocol zero as 'ip' for IPv4, and 'hopopt' for IPv6, which can be used with conntrack as '-p ip' or '-p hopopt'. However it's equivalent, '-p 0' is considered unsupported. Change the range check in findproto() to allow zero as well. Signed-off-by: Brian Haley <bhaley@redhat.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
