Description ddrinnon 2018-11-29 18:30:53 UTC
It seems the latest update to net/chrony 3.4 has broken the chronyd server if the chrony.conf option bindaddress is set, such as:


If the bindaddress is commented out, then time clients can get time from the chronyd server, but then that opens up the port on all interfaces on a multi-homed server.
Comment 1 Morgan Vandagriff 2018-11-30 18:20:22 UTC
I can confirm. Seeing the same thing. It's a real problem on a host with multiple jails, as chrony on the host is now listening on all jail IPs.

  net/chrony: Fix chrony running as server and using bindaddress

  On FreeBSD, sendmsg() fails when IP_SENDSRCADDR specifies a source
  address on a socket that is bound to the address. This prevents a server
  configured with the bindaddress directive from responding to clients.

  Add a new variable to check whether the server IPv4 socket is not bound
  before setting the source address.
