[PATCH v2 5/5] bpf: Add an iterator selftest for bpf_sk_storage_get

From: Florent Revest The eBPF program iterates over all files and tasks. For all socket files, it stores the tgid of the last task it encountered with a handle to that socket. This is a heuristic for finding the "owner" of a socket similar to what's done by lsof, ss, netstat or fuser.
