In fact, they explicitly disabled NFTABLES in their kernel config. You may want to ponder for a little while why that might be. I think netfilter is at a real crossroads right now. In my opinion, any resistence to integration with eBPF and XDP will lead to even less adoption of netfilter as a technology. Therefore my plan is to move everything to be integrated around these important core technologies. For the purposes of integration, code coverage, performance, and the ability to juxtapose different bits of eBPF code into larger optimized code streams that can also be offloaded into hardware. -- 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
