Hi,
and after a little bit of time, here comes the v6 of the HID-BPF series.
Again, for a full explanation of HID-BPF, please refer to the last patch in this series (23/23).
This version sees some improvements compared to v5 on top of the usual addressing of the previous comments:
- now I think every eBPF core change has a matching selftest added
- the kfuncs declared in syscall can now actually access the memory of the context
- the code to retrieve the BTF ID of the various HID hooks is much simpler (just a plain use of the BTF_ID() API instead of loading/unloading of a tracing program)
- I also added my HID Surface Dial example that I use locally to provide a fuller example to users
Looking great. Before another respin to address bits in patch 12 let's land the first ~8 patches, since they're generic useful improvements.
Kumar, could you please help review the verifier bits?
Sure, I'll take a look.
