Bug ID: 1065001 Summary: Starting docker service removes IPv6 default route Product: Fedora EPEL Version: el6 Component: docker-io Assignee: lsm5@redhat.com Reporter: redhat@subs.maneos.org QA Contact: extras-qa@fedoraproject.org CC: admiller@redhat.com, golang@lists.fedoraproject.org, lsm5@redhat.com, mattdm@redhat.com, mgoldman@redhat.com, skottler@redhat.com, vbatts@redhat.com
Description of problem:
The docker init script does this:
preexec="/sbin/sysctl" [ -x $preexec ] || exit 6 $preexec -w net.ipv4.ip_forward=1 > /dev/null 2>&1 $preexec -w net.ipv6.conf.all.forwarding=1 > /dev/null 2>&1
These two settings are not quite equivalent. In particular, net.ipv6.conf.all.forwarding=1 disables autoconfiguration.
Version-Release number of selected component (if applicable):
0.7.6-2.el6
How reproducible:
Steps to Reproduce: 1. Start with a host using stateless IPV6 networking configuration. 2. Install docker-io. 3. Start docker-io service.
Actual results: Loss of ::/0 route (previously auto-configured via a router advertisment).
Expected results: No changes in routing table.
Additional info:
According to Documentation/networking/ip-sysctl.txt setting net.ipv6.conf.xxx.accept_ra to 2 should re-enable it for that interface but that doesn't seem to work for me.
