Libbpf userspace function bpf_link__disconnect
Release "ownership" of underlying BPF resource
Definition
void bpf_link__disconnect(struct bpf_link *link);
Parameters
link: BPF link to disconnect
Usage
Disconnected link, when destructed through bpf_link__destroy call won't attempt to detach/unregister that BPF resource. This is useful in situations where, say, attached BPF program has to outlive userspace program that attached it in the system. Depending on type of BPF program, though, there might be additional steps (like pinning BPF program in BPFFS) necessary to ensure exit of userspace program doesn't trigger automatic detachment and clean up inside the kernel.
