Hi Florian, Quite the contrary, the new code would be if (ct->master || help) return; This will relax the if statement condition, which will decrease the __nf_ct_try_assing_helper() call count. Anyway, I use a Broadcom patched 3.4.11, but I checked the origin of the call, it does not originate from their patches, in comes from nf_nat_setup_info(ct, &newrange, NF_NAT_MANIP_SRC) call found in masquerade_tg(). Helper auto assignments are enabled (in that version is not possible to inhibit them outside loading nf_conntrack_ftp with ports=0). -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
