NetworkManager segfaults when restarting and interface is up with an IP assigned [SOLVED]

[walterw]

Hi all,

This one has been bugging me for a while.  At first, I thought it might be related to running a hardened system, so I decided to migrate to a more vanilla install, but I get the same thing repeatably.  I' running gentoo sources 4.13.9 and NetworkManager 1.4.4-r1.

I can reproduce this problem on any of my machines as long as I restart NetworkManager when an interface is up.  The workaround for me is to bring down the interface (ifconfig eth0 down) before restarting NetworkManager.

 

Short of running strace, what else can I do to sort this out?

My openresolvconf configuration was invalid:

 

# Use the local name server
name_servers=127.0.0.1

# added for dnscrypt + dnssec
#options edns0

 

The last line had the bug in it and that caused openresolvconf to crash.
