Description Scott Schmit 2010-05-02 22:10:57 UTC

Description of problem:
When configuring a connection with manual IPv6, connecting to the network results in SLAAC addresses as well as the manual one(s).

On one hand, IPv6 isn't like IPv4 -- you can have multiple addresses on your interface, so the extra addresses are probably harmless, but I can imagine where people would find the extra addresses to be undesirable (POLA/tradition, don't want the machine to respond to an Internet-accessible address, manual addresses interfere somehow with the SLAAC, etc).

Version-Release number of selected component (if applicable):
NetworkManager-0.8.0-10.git20100502.fc12.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Configure a connection to have the IPv6 method set to manual (IPv4 to whatever you want -- disable is probably the least distracting)
2. Connect to that connection
3. Look at ip addr, ip -6 route, /etc/resolv.conf
  
Actual results:
SLAAC addresses and routes are configured

Expected results:
SLAAC addresses and routes are not configured, and must be manually configured if desired. (I'm not counting the Link Local address as SLAAC here)

So accept_ra isn't getting set back to 0 when we're using manual mode, that's the problem here I believe.

I can confirm that this now works with NetworkManager-0.8.0-11.git20100503.fc12.x86_64
