Bug ID: 232555
Summary: local_unbound fails to start if root.key is empty.
Product: Base System
Version: 11.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: b...@freebsd.org

Patch for /etc/rc.d/local_unbound
It seems to be possible that local_unbound gets into state where
/var/unbound/root.key exists but is empty as a result of unclean shutdown.
The command that regenerates the file is unbound-anchor, which rebuilds it if
it doesn't exist or it is empty (stated in man page). However,
/etc/rc.d/local_unbound doesn't invoke it if root.key exists, even as
zero-length file.
This results in situation where the local_unbound service no longer starts, it
is also unable to recover from such condition automatically. This leaves the
machine without working DNS service:
Oct 23 09:08:39 local-unbound-test unbound: [947:0] notice: init module 0:
validator
Oct 23 09:08:39 local-unbound-test unbound: [947:0] error: failed to read
/root.key
Oct 23 09:08:39 local-unbound-test unbound: [947:0] error: error reading
auto-trust-anchor-file: /var/unbound/root.key
Oct 23 09:08:39 local-unbound-test unbound: [947:0] error: validator: error in
trustanchors config
Oct 23 09:08:39 local-unbound-test unbound: [947:0] error: validator: could not
apply configuration settings.
Oct 23 09:08:39 local-unbound-test unbound: [947:0] error: module init for
module validator failed
Oct 23 09:08:39 local-unbound-test unbound: [947:0] fatal error: failed to
setup modules
Simple fix to solution would be the change the rc.d script so that it has same
logic as unbound-anchor, ie. run it if the file does not exist OR it is empty.
Patch attached.
