[Bug 1228204] Re: avahi-daemon fails to start if the kernel does not support SO_REUSEPORT

[Launchpad Bug Tracker]

This bug was fixed in the package avahi - 0.6.31-2ubuntu4

---------------
avahi (0.6.31-2ubuntu4) saucy; urgency=low

  * When userspace defines SO_REUSEPORT we will attempt to enable socket
    port number reuse.  However if the running kernel does not support
    this call it will fail preventing daemon startup.  If this call is
    present but fails ENOPROTOOPT then we know that actually the kernel
    does not support it and we should continue as if we did not have the
    call at all.  (LP: #1228204)

Title:
  avahi-daemon fails to start if the kernel does not support
  SO_REUSEPORT

Status in “avahi” package in Ubuntu:
  Fix Released
Status in “avahi” source package in Saucy:
  Fix Released

Bug description:
  When running with a version of avahi-daemon compiled with SO_REUSEPORT
  available, failure of this call fails startup of the daemon.  This
  occurs in the panda images where we have a very old kernel relative to
  userspace which does not support the call at all.

  Where this call fails ENOPROTOOPT that implies the call is not
  implemented, and if we ignore it we are in no worse situation that we
  were when the code was not supported.
