Hi Rasmus, I have trouble booting my test machine with this patch in -mm:
commit bb2e066c6943e62e9650bb129f416dacf138f8b1 Author: Rasmus Villemoes <[email protected]> Date: Wed Jan 14 01:00:44 2015 +0000 lib/vsprintf.c: don't try to fix pointer wrap-around Actual kernel buffers can't wrap into the user address space. If someone manages to pass a buf/size combination that wraps, it is most likely due to a bug in the caller. Instead of trying to fix it by using a smaller part of the buffer, bail out.

A WARN_ON_ONCE() inside vsnprintf() looks like it would deadlock instantly when triggering this overflow from printk(), no? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
