Fri Jun 15 18:01:41 2012 GMT: jabberd2 broke after upgrade to Ubuntu 12.04

After upgrading edge.cmeerw.net I noticed that jabberd2 broke with very weird symptoms. In the end it turned out that a fix for CVE-2012-0876 in the expat XML parser has some very undesirable side-effects. It randomises hash calculations in the library, but to do that it uses srand/rand every time an XML parser is created (re-seeding the random number generator with the current time via srand). Unfortunately, jabberd2 also uses random numbers to create unique ids and it is those ids that are now not unique any more when two connections are created within a second (as an XML parser is created for each connection and the random number generator is re-seeded with the same timestamp, resulting in the same "random" id being used by jabberd2). Oh dear, using srand inside a library is evil...
