--3V7upXqbjpZ4EhLz Content-Type: text/plain; charset=us-ascii Content-Disposition: inline I ported the NetBSD -Wnetbsd-format-audit warning option to gcc which checks for non-constant format strings for auditing purposes. It seems to work, although of course it gives lots of false positives. Patches at http://www.freebsd.org/~kris/gcc-format-warning.patch I'm going to try and generate a master list of these warnings from a 'make world' so they can be examined. NetBSD have done a lot of cleanups here (though I'd expect most are not security-relevant). They also have a library function they have just committed which checks for compatability of format strings, which I'm going to look at porting as well. Feedback welcomed.
