It's unnecessary to loading kprobe_skb_lifetime_termination bpf prog when --filter-track-skb is not enabled. For next commit, it skips loading other skb-tracking bpf progs too. Signed-off-by: Leon Hwang <[email protected]>
With --filter-track-skb option, we're able to track sbk by its address. Then, as for skb's clones/copies, we're able to track them too, by the way `fexit` on `skb_clone()` and `skb_copy()`. Signed-off-by: Leon Hwang <[email protected]>
