Red Hat Bugzilla – Bug 588163
Manual IPv6 configures SLAAC as well
Last modified: 2010-05-04 07:31:09 EDT
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):
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
SLAAC addresses and routes are configured
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.
Upstream fix is 7926b3ca95f2c0c611e271f805437cca9dc004ea.
I can confirm that this now works with NetworkManager-0.8.0-11.git20100503.fc12.x86_64
