Dan Carpenter f740c34ee5 bpf: fix oops on allocation failure ... "err" is set to zero if bpf_map_area_alloc() fails so it means we return ERR_PTR(0) which is NULL. The caller, find_and_alloc_map(), is not expecting NULL returns and will oops. Fixes: 174a79ff95 ("bpf: sockmap with sk redirect support") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Alexei Starovoitov <ast@kernel.org> Acked-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: David S.
