src: fix incorrect building and parsing of the NFCTH_POLICY_SETX attributeHEADmaster
In nfct_helper_nlmsg_build_policy(), we always set the attribute type to NFCTH_POLICY_SET, so we cannot add more than one nfct_helper_policy to the kernel. Also: in nfct_helper_nlmsg_parse_policy(), we will increase the helper->policy_num for each nfct_helper_policy, but we mistakenly set it to the total number of nfct_helper_policy. So when the total number is more than 3, later out of bound access will happen. Signed-off-by: Liping Zhang <zlpnobody@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
