-Subject: bpftool: Fix cgroup command to only show cgroup bpf programs
-
-From: Martin KaFai Lau <martin.lau@kernel.org>
-
-[ Upstream commit b69d4413aa1961930fbf9ffad8376d577378daf9 ]
-
-The netkit program is not a cgroup bpf program and should not be shown
-in the output of the "bpftool cgroup show" command.
-
-However, if the netkit device happens to have ifindex 3,
-the "bpftool cgroup show" command will output the netkit
-bpf program as well:
-
-> ip -d link show dev nk1
-3: nk1@if2: ...
- link/ether ...
- netkit mode ...
-
-> bpftool net show
-tc:
-nk1(3) netkit/peer tw_ns_nk2phy prog_id 469447
-
-> bpftool cgroup show /sys/fs/cgroup/...
-ID AttachType AttachFlags Name
-... ... ...
-469447 netkit_peer tw_ns_nk2phy
-
-The reason is that the target_fd (which is the cgroup_fd here) and
-the target_ifindex are in a union in the uapi/linux/bpf.h. The bpftool
-iterates all values in "enum bpf_attach_type" which includes
-non cgroup attach types like netkit. The cgroup_fd is usually 3 here,
-so the bug is triggered when the netkit ifindex just happens
-to be 3 as well.
-
-The bpftool's cgroup.c already has a list of cgroup-only attach type
-defined in "cgroup_attach_types[]". This patch fixes it by iterating
-over "cgroup_attach_types[]" instead of "__MAX_BPF_ATTACH_TYPE".
