Summary
bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE
Details

In the Linux kernel, the following vulnerability has been resolved:

bpf: Add BPFPROGTYPECGROUPSKB attach type enforcement in BPFLINKCREATE

bpfprogattach uses attachtypetoprogtype to enforce proper attach type for BPFPROGTYPECGROUPSKB. linkcreate uses bpfprogget and relies on bpfprogattachcheckattachtype to properly verify progtype <> attachtype association.

Add missing attachtype enforcement for the linkcreate case. Otherwise, it's currently possible to attach cgroup_skb prog types to other cgroup hooks.
