Masami Hiramatsu 579c977253 x86/uprobes: Do not use prefixes.nbytes when looping over prefixes.bytes ... commit 4e9a5ae8df5b3365183150f6df49e49dece80d8c upstream. Since insn.prefixes.nbytes can be bigger than the size of insn.prefixes.bytes[] when a prefix is repeated, the proper check must be insn.prefixes.bytes[i] != 0 and i < 4 instead of using insn.prefixes.nbytes. Introduce a for_each_insn_prefix() macro for this purpose. Debugged by Kees Cook <keescook@chromium.org>.
