Subject: Error loading xdp program that worked with bpf_load
Date: Wed, 10 Jun 2020 14:01:09 -0700	[thread overview]
Message-ID: <CAMDScmnpbPgs+mB_aMY16aXLMMWBgfu0sqna06MH8RPoGpw7_Q@mail.gmail.com> (raw)

I used this to load my xdp program
https://github.com/torvalds/linux/blob/master/samples/bpf/bpf_load.c
but it doesn't seem to work on new style maps so I am using libbpf
bpf_object__open now.

But now it shows this

libbpf: Error loading BTF: Invalid argument(22)
libbpf: magic: 0xeb9f

flags: 0x0

[2] PTR (anon) type_id=4
[3] INT int size=4 bits_offset=0 nr_bits=32 encoding=SIGNED
more type information....
libbpf: Error loading .BTF into kernel: -22.

How do I fix this?
