Subject: [patch] sparc64: make string buffers large enough
Date: Fri, 25 Nov 2016 11:03:55 +0000 [thread overview]
Message-ID: <20161125110338.GD5938@mwanda> (raw)
My static checker complains that if "lvl" is ULONG_MAX (this is 64 bit)
then some of the strings will overflow. I don't know if that's possible
but it seems simple enough to make the buffers slightly larger.
