- Store foreign bpf programs in cgroup context. A program is considered foreign if it was loaded to a kernel by an entity external to systemd, so systemd is responsible only for attach and detach paths. - Support the case of pinned bpf programs: pinning to bpffs so a program is kept loaded to the kernel even when program fd is closed by a user application is a common way to extend program's lifetime. - Aadd linked list node struct with attach type and bpffs path fields.
