No more gw since upgrade to radvd 2.1 #32

Closed seblu closed 10 years ago

seblu commented 10 years ago

Hello,

During the test to push radvd 2.1 on archlinux, I discovered that my hosts have loosed their ipv6 gateway since the upgrade from 1.4[1] to 2.1[2].

I'm using the following config file

# vim:set ts=2 sw=2 ft=perl noet :

interface brlan
{
    AdvSendAdvert on;
    AdvSourceLLAddress on;

    MinRtrAdvInterval 10;
    MaxRtrAdvInterval 30;

    # Disable Mobile IPv6 support
    AdvHomeAgentFlag off;

    prefix 2a01:240:fe00:8205::/64
    {
        AdvOnLink on;
        AdvAutonomous on;
    };

  RDNSS 2a01:240:fe00:8205::1
  {
                    # advised by logs to be <= 2*MaxRtrAdvInterval
          AdvRDNSSLifetime 45;
  };

  DNSSL h.seblu.net
  {
          AdvDNSSLLifetime 45;
  };

};

I have the following output from systemd when I run radvd 1.4

I've reproduced the issue locally. I should have a fix in a few days if not sooner.

Thanks, Reuben

Please checkout and test the for_seblu branch and let me know if that solves the problem...

That's seems to be a fix. Route is back and ipv6 works again.

Not really on purpose. The make check target is new and uses the CHECK framework. If you run the check_all binary, you'll see all the test results. I'd like to see the tests run individually in the make check output, but I haven't figured out a good way to do that yet.

If you could let me know how to get my gpg key up at gpg.mit.edu I'd appreciate it.

About tests, even tough make check with an easy to read output is preferable from a packager point of view, whatever the output is, it's fine as long as make check return 0 if there is no error. Currently information are not consistant. Total let think there is ony one test run, but when it fails we see 23 checks run.

As you can see, I cannot build release 2.3 package because make check fail (!=0).

I didn't include the test/test_rdnss.conf in DIST_EXTRA...

I added it and posted 2.4. Hopefully that'll work.
