Hi,
I think this patch is causing user-space breakage, see [0].
The gist is that we do BPF_PROG_RUN of a socket filter with 14 byte input to determine whether BPF_PROG_RUN is available or not. I'll fix this in cilium/ebpf, but I think this patch needs more work since users may be doing the same thing in their code.
Thanks, Lorenz
