Hi All,
Thanks for joining the call today, below you may find my notes.
Upcoming conference info:
netdev - Japan - early October
Alexei, Daniel B, Jesper voiced their ack that they would attend
Plumbers - Santa Fe - early November
Alexei - to submit talk on BPF+LSM
Brenden - to submit talk on llvm rewrite
cgroups patch status:
v4
establishes a model for how bpf to be attached to cgroup
nice basis for later lsm work
- no controversial issues came up on list
- where to put egress hooks?
- for security, would need no-new-priv type of flag, which children
cannot overwrite
- current model would eventually work for instance for Sargun's use
case
llvm ir rewrite concept
- backend has lost information for some types of checks
- often as difficult as in-kernel verifier
- meaning earlier llvm pass would be useful
- serves as learning exercise to add features like better debug
- con: passes cannot return as clean an error message as rewriter
- more likely to be upstreamable, plugin module
- ai: will continue effort, medium priority research project
note:
python core team talking about adding usdt probes, cool!
