Here is the summary with links:
- [v2,bpf,1/2] bpf: add missing check_func_arg_reg_off() to prevent out-of-bounds memory accesses
https://git.kernel.org/bpf/bpf-next/c/ec2b9a5e11e5
- [v2,bpf,2/2] bpf: add new negative selftests to cover missing check_func_arg_reg_off() and reg->type check

You are awesome, thank you!
