Subjectsmatch update / 2.5.64 / kbugs.org

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...

mysql> select kernelver, script, count(script) from bugs where kernelver = "2.5.64" group by script, kernelver;
+-----------+-------------------+---------------+
| kernelver | script | count(script) |
+-----------+-------------------+---------------+
| 2.5.64 | Dereference | 469 |
| 2.5.64 | GFP_DMA | 7 |
| 2.5.64 | ReleaseRegion | 14 |
| 2.5.64 | SpinlockUndefined | 44 |
| 2.5.64 | SpinSleepLazy | 4 |
| 2.5.64 | UncheckedReturn | 119 |
| 2.5.64 | UnFree | 333 |
| 2.5.64 | UnreachedCode | 28 |
+-----------+-------------------+---------------+
