=== Discussion === Kenny: How is transition to groups.io mailer? - no complaints
Yonghong: - rewriter improvements - lot of new corner cases being worked on - some python3 improvements - request to enable tests
Brenden: - to implement fedora 28, ubuntu 18 buildbots - python3 testing support in test cases
Saeed: - XDP metadata RFC looking for feedback - xdp programs currently ask for specific flags, cross reference with netdev supported flags, fail otherwise - is this behavior acceptable? - pro: better than detecting at runtime and silently failing - con: flag checking prior to metadata conversion at packet ingress is burdensome to the driver tightly bound to kernel version - if metadata at the front of the packet needs to be read first, could be caching/perf issues as metadata is moved around - data duplicated, e.g. checksum in 3 places: descriptor+skb+xdp_md
Okash: - BTF: - some changes in pahole to convert dwarf function description to btf
Yifeng: - OVS BPF rfc is pushed - Joe planning to review the patches - conntrack support in progress (adding helper approach) - would be nice to have a native conntrack implementation - question: how to handle reassembly?
