This repo reproduces an interaction between the Go runtime CPU profiler and the BPF_PROG_LOAD syscall on Linux.
Set SetCPUProfileRate(1000) causes the thread executing the syscall to be interrupted every ~1 ms. This in turn leads to BPF_PROG_LOAD to never finish, given a complex enough BPF program.
test_cls_redirect.o is a precompiled version of test_cls_redirect.c from the Linux kernel sources.
$ go run -exec sudo . # sudo is required to allow the BPF syscall
