dh key: get rid of stack allocated array
We're interested in getting rid of all of the stack allocated arrays in the kernel: https://lkml.org/lkml/2018/3/7/621 This particular vla is used as a temporary output buffer in case there is too much hash output for the destination buffer. Instead, let's just allocate a buffer that's big enough initially, but only copy back to userspace the amount that was originally asked for. v2: allocate enough in the original output buffer vs creating a temporary output buffer Signed-off-by: Tycho Andersen <tycho@tycho.ws> Reviewed-by: Kees Cook <keescook@chromium.org> CC: David Howells <dhowells@redhat.com> CC: James Morris <jmorris@namei.org> CC: "Serge E.
