/* * Smatch is an open source c error checker based * on the papers about the Stanford Checker. * (http://smatch.sf.net) The documentation on coding * smatch checks has been updated since my last email to * this list. * */
The smatch bugs for kernel 2.5.64 are up. The new url for the smatch bug database is http://kbugs.org.
One new script from Monday was "UnFree." This check looks for variables that aren't freed on the error paths. http://kbugs.org/cgi-bin/index.py?page=bug_list&script=UnFree&kernel=2.5.64
The bug database is still under heavy construction (ie it is really bad). But I hope to improve it some more this week. Also I plan to add some documentation etc.
The possible bug count for 2.5.64 was 1018. Eventually this information will all be available in a stats page but for now I'll just post the raw SQL...
