Hi All,
Thanks for attending the meeting today. As usual, here are my notes.
=== Discussion ===
Bjorn
- AF_XDP zero copy implementation RFC on netdev
- some uapi concerns, may need to back out changes
- but, over next couple weeks before merge window, discuss and improve in
hopes of merging
- clean up non-intel code, respin, leave out i40e patches at the end
- separate i40e cleanup spin
- bcm may try to join as 2nd vendor to flesh out uapi
- some discussion of common code organization
- xdp in separate file helps backporting
Yonghong
- some python3 fixes
- proposals for improved container support
- rewriter complexity increasing
- tracing event introspection
Martin
- BTF id landed
- working on bpftool support
- still using pahole to convert dwarf
- still unclear how integration with llvm will look
Jiong
- dominator tree info RFCs pushed
- significant mem/exec time costs to run (e.g. 2x more, 3x slower)
John
- induction variable tracking in progress
- next: min/max value tracking
both: to work on topic branch under bpf-next
William
- tried workaround from Yonghong
- still need to dig into root cause
Joe
