<youpi> we really need something that is able to automatically check port deallocation
<youpi> at least for the trivial cases, for which we do have bugs I'm currently fixing...
<pochu> test suite? :)
<pochu> won't magically find them though, so not what you've asked for...
<youpi> test suites can trigger some of the bugs yes
<youpi> which is already a good thing
<youpi> of course the coverage can't be perfect
<youpi> one of the bugs I fixed happened only for setuid binaries for instance

portseal can automatically detect port leaks. It is somewhat intrusive, as it leverages a source-transformation and hence requires a recompilation of the code that contains the port leak. Currently, it is a prototype. If you are looking for a port leak, I'd love you to try it though:
