Hi. So, we clarified that some of the problems were not caused by the kernel at all. The only thing missing is support to probe_read_kernel and probe_read_user on 4.15 kernels. Is that needed for the offering?
If I didn't get it right, I am sorry. So, in order for us to meet your expectations, I'll try to understand better what are the needs here: 1) Do you want support on 4.15 kernel on Ubuntu 18.04, right? Or is the offering based on Ubuntu 20.04? 2) Do you expect to be able to use LLVM/clang 10? Or is LLVM/clang 8 sufficient for your needs? The bug has only been open for the linux package, so we would need to get folks behind LLVM involved, or try to fix this on the kernel somehow, which might delay things a little. Being able to use LLVM/clang 8, it seems, would be a best fit to a short deadline. 3) Building and running samples/bpf/ is not something we test. And though it might help us catch regressions, I would suppose it's not a requirement for the offering. If I am wrong in that supposition, are you relying on the source package for something? Or is anything shipped in binary packages incorrect (like that s930x typo) preventing things from building correctly? Right now, the best course we have, in case what you need is the probe functions on 4.15 is to get this available on a kernel in -proposed in 3 weeks, and in -updates in 6 weeks. Would that work? Thank you.
