I would also highly welcome the inclusion of this patch, since it
provides functionality that is required for legal reasons.
Existing privacy laws in Germany (and, I think, in other EU states as
well) do not allow servive providers to log data that are not required for
providing their service. There has been a recent lawsuit in Germany
where the court has found that customary logging of IP adresses is illegal
(i.e. logging may only be enabled on a case-by-case basis, e.g. during a
It is very difficult right now to run a Linux (or Unix) system while
complying with the law. Basically you would need to jump through loops
and run scripts to anonymize data that should never have hit the disk
in non-anonymized form. Thus I would be glad if it were possible to
strip IP adresses in syslog.
