Hi Jesper,
I tried adding your solution, bpf_debug, and I'm now able to run the
program with no errors but the trace_pipe file stays empty.
I just added this to my program:
#ifdef DEBUG
/* Only use this for debug output. Notice output from bpf_trace_printk()
* end-up in /sys/kernel/debug/tracing/
Notice, there are two mailing lists (Cc'ed) that you should likely ask
these kind of questions on (instead of netdev), depending on if this is
mostly related to bpf (iovisor-...@lists.iovisor.org) or somehow
related to XDP (xdp-newb...@vger.kernel.org).
