When CONFIG_NETKIT=y, bpftool-cgroup shows error even if the cgroup's path is correct: $ bpftool cgroup tree /sys/fs/cgroup CgroupPath ID AttachType AttachFlags Name Error: can't query bpf programs attached to /sys/fs/cgroup: No such device or address >From strace and kernel tracing, I found netkit returned ENXIO and this command failed. I think this AttachType(BPF_NETKIT_PRIMARY) is not relevant to cgroup. bpftool-cgroup should query just only cgroup-related attach types. v2->v3: - removed an unnecessary check v1->v2: - used an array of cgroup attach types Signed-off-by: Kenta Tada <tadakentaso@gmail.com> Reviewed-by: Quentin Monnet <qmo@kernel.org> Link: https://lore.kernel.org/r/20240607111704.6716-1-tadakentaso@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> |
