I'll be adding lsm cgroup specific helpers that grab trampoline mutex. No functional changes. Signed-off-by: Stanislav Fomichev <[email protected]>
Allow attaching to lsm hooks in the cgroup context. Attaching to per-cgroup LSM works exactly like attaching to other per-cgroup hooks. New BPF_LSM_CGROUP is added to trigger new mode; the actual lsm hook we attach to is signaled via existing attach_btf_id. For the hooks that have 'struct socket' as its first argument, we use the cgroup associated with that socket. For the rest, we use 'current' cgroup (this is all on default hierarchy == v2 only). Note that for the hooks that work on 'struct sock' we still take the cgroup from 'current' because most of the time, the 'sock' argument is not properly initialized. Behind the scenes, we allocate a shim program that is attached to the trampoline and runs cgroup effective BPF programs array. This shim has some rudimentary ref counting and can be shared between several programs attaching to the same per-cgroup lsm hook. Note that this patch bloats cgroup size because we add 211 cgroup_bpf_attach_type(s) for simplicity sake. This will be addressed in the subsequent patch.

Previous patch adds 1:1 mapping between all 211 LSM hooks and bpf_cgroup program array. Instead of reserving a slot per possible hook, reserve 10 slots per cgroup for lsm programs. Those slots are dynamically allocated on demand and reclaimed. This still adds some bloat to the cgroup and brings us back to roughly pre-cgroup_bpf_attach_type times. It should be possible to eventually extend this idea to all hooks if the memory consumption is unacceptable and shrink overall effective programs array.

For now, allow only the obvious ones, like sk_priority and sk_mark. Signed-off-by: Stanislav Fomichev <[email protected]>
