This patch uses nfct_help() to detect whether an established connection needs conntrack helper instead of using test_bit(IPS_HELPER_BIT, &ct->status). The reason for this modification is that IPS_HELPER_BIT is only set when the conntrack helper is attached by explicit CT target. However, in the case that a device enables conntrack helper via the other ways (e.g., command "echo 1 > /proc/sys/net/netfilter/nf_conntrack_helper") , the status of IPS_HELPER_BIT will not present any change. That means the IPS_HELPER_BIT might lose the checking ability in the context. Signed-off-by: HsiuWen Yen <y.hsiuwen@gmail.com> |
