[PATCH 0/2] fortify: Add run-time WARN for cross-field memcpy()
From: Kees Cook

Hi,
I'm hoping to at least get this into -next to see how noisy it ends up
being. I've tracked down several false positives that are getting fixed,
but I'd like to see this get wider testing. For details, see patch 1,
but this is the run-time half of the recent FORTIFY_SOURCE memcpy()
bounds checking work.
