Title:
Constant _ip6_config_add_nameserver: assertion `IN6_ARE_ADDR_EQUAL
(nameserver, &nameservers[i]) == FALSE' failed messages in syslog
Status in “network-manager” package in Ubuntu:
Fix Released
Status in “network-manager” source package in Precise:
In Progress

Bug description:
[Impact]
Causes extra messages to spam syslog on every address addition netlink
message, or every route change. (Very often)
No actual behavioral impact aside from a log which is potentially very
rapidly growing due to these warning messages.
[Test Case]
This requires an Apple Airport device connected in IPv6 tunneling mode.
1) Connect the computer to the Airport device's network.
You should see IN6_ARE_ADDR_EQUAL assertions without the patch, and no
such messages with the patch applied.
[Regression Potential]
Changes testing logic for IP address comparison to return silently rather
than asserting (because assertions cause the messages to be printed to syslog);
so no actual impact on that side except for the messages not being printed out.
However, this introduces duplicates checking for the routes and addresses as
well, which has a small potential for extra routes to be missing if the
duplicate checking fails to consider extra flags which would make the
similar-looking routes or addresses actually very different.
----
When both the Ethernet and wlan are connected to an Apple Airport
running IPv6.
