Title:
  openssh server 6.6 does not report max auth failures

Status in openssh package in Ubuntu:
  Fix Released
Status in openssh source package in Trusty:
  Fix Committed

Bug description:
  Brute force attacks against openssh on Trusty will not log "max auth"
  key-based attempts, leaving their brute forcing invisible to the logs
  and anything that consumes logs, like fail2ban. Version 6.7 introduced
  the logging, but it's missing in Trusty. Since Trusty is LTS, it would
  seem sensible to have this feature backported.

  [Impact] Bruce force attempts using private keys are invisible to
  logs, which renders defenses like fail2ban useless.

  [Test case] Create 20 SSH keys, try to log in over SSH, note lack of
  logging the failures.

  [Regression Potential] Very unlikely regression potential as the "max
  auth" condition is already handled in code, it just wasn't logging.
  The change only adds the missing logging.
