| H A D | libbpf_internal.h | diff 3ec84f4b1638495ebff068a668dc417b4de5727e Sun Aug 15 09:06:03 CEST 2021 Andrii Nakryiko <andrii@kernel.org> libbpf: Add bpf_cookie support to bpf_link_create() API
Add ability to specify bpf_cookie value when creating BPF perf link with
bpf_link_create() low-level API.
Given BPF_LINK_CREATE command is growing and keeps getting new fields that are
specific to the type of BPF_LINK, extend libbpf side of bpf_link_create() API
and corresponding OPTS struct to accomodate such changes. Add extra checks to
prevent using incompatible/unexpected combinations of fields.
