I needed to apply some shaping on incoming traffic to preserve bandwidth for streaming services. bering-uclibc version 5.2.4 appeared to offer the necessary facilities - linux 4.1.16 supports it and apparently tc supports it too but in actual fact, although tc accepts the 'action connmark' action in a tc filter command, it fails to talk correctly to the kernel.
Rooting around in github, it looks like the patch applied to tc, supposedly to support connmark, in fact does nothing and it also screws up the command sent on the netlink socket so the kernel rejects it. In trying to resolve this, I downloaded the leaf-bering dev environment from github - all several gigabytes! However the instructions in the README bear little relation to the actual config required, and I never did work out how to build the environment successfully. I solved it by using buildroot-2015.11 to build tc updated to version 4.4.0, against uclibc-0.9.33.2 and this works properly on my installation. Can I suggest you take the m_connmark.c file from tc in the iproute2 version 4.4.0 package. This will correctly parse the connmark action in tc filter commands & generate the necessary commands on the netlink socket. regards, John Sager ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
