tools: bpf: handle NULL return in bpf_prog_load_xattr()
bpf_object__open() can return error pointer as well as NULL. Fix error handling in bpf_prog_load_xattr() (and indirectly bpf_prog_load()). Fixes: 6f6d33f3b3d0 ("bpf: selftests add sockmap tests") Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Quentin Monnet <quentin.monnet@netronome.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
