Is XDP_PASS indeed a supported action, and if so can you provide any recommendations for configuring XDP on ec2 instances? $ modinfo enaįilename: /lib/modules/5.4.20-12.75.amzn2.x86_64/kernel/drivers/amazon/net/ena/ena.koĭescription: Elastic Network Adapter (ENA)Īuthor:, Inc. I have had success loading an XDP program and using XDP_TX.
Install tcpdump amazon linux ami install#
# Install basic XDP_PASS program in native modeĮxpected result: All packets are passed up to normal network stack for processingĪctual result: Connectivity to instance is lost, instance reachability check fails Yum install -y elfutils-libelf-devel perf kernel-headers clang llvm flex bison git
I couldn't find any ENA specific examples/recommendations for XDP configuration, so maybe I'm missing something.
Install tcpdump amazon linux ami driver#
Skimming over the driver code it seems like it should be supported, and perhaps the issue is in my configuration. Hi, I have been testing out the recently added XDP support but have had issues trying to use XDP_PASS.
