5 years agoEschew the rsyslogd PID file
Saj Goonatilleke [Mon, 11 Feb 2019 12:36:15 +0000 (23:36 +1100)]
Eschew the rsyslogd PID file

This PID file is not required, provides questionable operational value,
and can break logging in a Discourse application container.

On startup, rsyslogd will read `rsyslogd.pid` and self-terminate if it
finds another process on the system with the same PID as that which was
written to this file.  This behaviour is especially problematic when
running in a containerised environment:

- The processes that make up a container are more likely to be
  terminated without grace.  Any PID files persisted to the container's
  filesystem will become stale after an unclean shutdown.  (Separately,
  even when signalled with `SIGTERM` on graceful shutdown, rsyslogd will
  still fail to unlink this file.)

- PIDs on Linux are assigned sequentially.  When run in a unique `pid`
  namespace, a container's process table is subject to little entropy.
  Thus, PID 'collisions' across container instantiations are not
  unlikely.

Altogether, it is easy for rsyslogd to DoS itself on startup by
mistaking another process in the container (e.g.: nginx) for an existent
rsyslogd process.  Unlinking this file guarantees a clean startup.

Newer releases of rsyslog support `-iNONE`, but -- of course -- this
feature is not supported in the rsyslog distribution included as part of
Ubuntu 16.04:

https://github.com/rsyslog/rsyslog/blob/527f19c56a80fd30354f32ad03bdacc1275f4aa8/ChangeLog#L1618-L1623

Vixie crond and nginx also employ PID files, though neither is
vulnerable to this failure mode.  Vixie cron wraps the fd with a flock;
the flock is used for mutual exclusion, not the underlying file itself.
nginx does not appear to use its PID file for mutual exclusion.
