Subject: Check if devops is valid before closing the device.
X-Git-Tag: release-1.1pre11~60^2
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=b12f122f1be89b49d8a3e39fb1b10c6e4d3ada94

Check if devops is valid before closing the device.

This fixes a segfault that occurs on exit if tinc fails before the
device is initialized (for example, if it fails to read the private
key).
