Network manager registering thousands of IPv6 addresses












0















I was noticing Network Manager and nm-applet were taking a lot of CPU, and in the process of inspecting it, I ran ip a. There were thousandos of temporary addresses associated with my Ethernet device. To give an idea, here's a line count:



ip a | wc
23128 120541 1537623


As soon as I plug in the Ethernet cable, Network Manager stars registering temporary IPv6 addresses, at an approximate rate of 2 addresses per second.



daemon.log shows multiple messages akin to the following



Feb 15 17:12:36 pulga nm-dispatcher: req:18 'dhcp6-change' [enp2s0]: new request (1 scripts)
Feb 15 17:12:36 pulga nm-dispatcher: req:18 'dhcp6-change' [enp2s0]: start running ordered scripts...


But they stop after a while.



On the other hand, syslog is littered with messages like the following:



Feb 15 17:12:51 pulga kernel: [  639.006713] IPv6: ipv6_create_tempaddr: retry temporary address regeneration


I also keep getting a duplicate IP warning in messages when connected to wireless network. Is this unrelated, or does it suggest something wrong with our network configuration?



Feb 15 17:13:49 pulga kernel: [  696.702519] IPv6: wlp3s0: IPv6 duplicate address fd9d:*:*::* used by e0:d5:*:*:*:* detected!
