Lorenz Bauer ca7ace8fd2 bpf: sockmap: Require attach_bpf_fd when detaching a program ... commit bb0de3131f upstream. The sockmap code currently ignores the value of attach_bpf_fd when detaching a program. This is contrary to the usual behaviour of checking that attach_bpf_fd represents the currently attached program. Ensure that attach_bpf_fd is indeed the currently attached program. It turns out that all sockmap selftests already do this, which indicates that this is unlikely to cause breakage.
