Hi All,
Thanks for attending the call today. Below are my notes.
=== Status ===
Alexei:
- 1 patch / day
- burdensome on alexei/daniel
- how to scale?
- to be discussed at netconf
- working on calls
- can load relatively large files
- rfc to come before netdev
- memory pressure in the verifier
- First TCP tracepoints accepted
- 5 more coming soon
- tcp set state has some corner case where it is missed
Daniel:
- fixes for verifier
- llvm generates some compare/jumps that aren't covered
- off by 1 in xdp data_end checks
- lpm needs get next key helper for dumping to userspace
- plan to support more drivers for xdp metadata
Brendan:
- LISA in a couple weeks - 2 bpf talks from Sasha, 1 from Brendan
Jakub:
- How to print 2nd phase bpf verifier output from offloaded program?
- quirk: it runs at attach time, not load time
- Maybe try a dry run somehow?
- Intermixing of driver specific errors?
- Same problem for maps
- Include offload check at load time instead
- New system call for "BPF_PROG_PREPARE", in between load and offload
- jit a loaded bpf prog for a specific arch/offload
