I think this patch is breaking something ... This irc: > - if (ports[i] == IRC_PORT) > - sprintf(irc[i].name, "irc"); > - else > - sprintf(irc[i].name, "irc-%u", i); > - > - ret = nf_conntrack_helper_register(&irc[i]); > + nf_ct_helper_init(&irc[i], AF_INET, IPPROTO_TCP, "irc", > + IRC_PORT, ports[i], &irc_exp_policy, 0, 0, > + help, NULL, THIS_MODULE); > + } This sip: > - if (ports[i] == SIP_PORT) > - sprintf(sip[i][j].name, "sip"); > - else > - sprintf(sip[i][j].name, "sip-%u", i); And this tftp: > - if (ports[i] == TFTP_PORT) > - sprintf(tftp[i][j].name, "tftp"); > - else > - sprintf(tftp[i][j].name, "tftp-%u", i); For example, if the user install the nf_conntrack_tftp module an specify the ports to "69,10069", then the helper name is "tftp" and "tftp-1". But apply this patch, the helper name will be changed to "tftp" and "tftp-10069", this may break the existing iptables rules which used the helper match or CT target.
