Re: Possible bug in traffic control?

I've been able to narrow the scope down, the issue is with macsec itself. I setup two hosts with a macsec link between them, and let a couple iperf3 sessions blast traffic across. At approximately 4.2 billion packets / 6TB data transferred one end stopped transmitting packets. Doing a tcpdump

I'm actually leaning towards macsec now. I'm at 6TB transferred in a double hop, no macsec over the bridge setup without triggering the fault. I'm going to let it continue to churn and setup a second testbed that JUST uses macsec without traffic control bridging to see if I can trip the issue

2.3 billion 1 byte packets failed to re-create the bug. To try and simplify the setup I removed macsec from the equation, using a single host in the middle as the bridge. Interestingly, rather than 1.3Gbits a second in both directions, it ran around 8Mbits a second. Switching the filter from

Possible bug in traffic control?

2018-10-09 Thread Josh Coombs
Hello all, I'm looking for some guidance in chasing what I believe to be a bug in kernel traffic control filters. If I'm pinging the wrong list let me know. I have a homebrew MACSec bridge setup using two pairs of PCs. I establish a MACSec link between them, and then use TC to bridge a second
