  ProxyDHCP replies on invalid range

Bug description:
  In Ubuntu 16.04, I've configured dnsmasq to reply on subnet=10.160.37.0/24, 
yet it replies even when it gets an IP on subnet=10.161.254.0/24.
  I've only seen this after clean system restart. If I restart dnsmasq later 
on, it works as expected.
  Maybe when dnsmasq starts, the network isn't up yet, and it incorrectly 
initializes some networking information? I'm using network-manager with DHCP.

[Touch-packages] [Bug 1651044] Re: ProxyDHCP replies on invalid range

2021-10-06 Thread Paride Legovini

Hi,

I had a look at [1] and AIUI this wasn't recognized as an upstream bug.
I also can't find a relevant Debian bug about this issue. The bug
description says it affected Xenial, which is now in Extended Security
Maintenance, so it's a Won't Fix there.

For >= Bionic we need confirmation from an affected user the bug is
still present and valid. Waiting for feedback I'm marking this bug
report as Incomplete.

2016-12-20 Thread Alkis Georgopoulos

Hi Christian,

Simon, the dnsmasq developer and Debian maintainer, frequently answers here in 
launchpad as well (and there's no upstream bug tracker).
In any case, I did forward the report to the dnsmasq mailing list:
http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2016q4/011010.html

Thank you for your feedback!

[Touch-packages] [Bug 1651044] Re: ProxyDHCP replies on invalid range

2016-12-20 Thread ChristianEhrhardt

Hi Alkis,
thank you for your report and your help to make Ubuntu better.
I like your preanalysis and agree to your assumption of some sort of bad 
initialization.

This bug is present in Debian too, and Ubuntu currently doesn't make any 
changes over the Debian package. So this bug would be best fixed directly in 
Debian, and then Ubuntu will pick up the fix automatically.
The only delta you see in Xenial is a security fix, so not a lot of "Ubuntu 
special" that could break it.

Also the versions are pretty much up to date - 2.76 as in Yakkety is the latest 
upstream.
I checked the changelog but there is no mentioning of the issue you are facing, 
yet if easily possible for you it might be worth checking the same on Yakkety 
or even Zesty.

I almost assume that it might be an upstream issue with dnsmasq itself, but in 
that case as well Debian should be notified to be able to pick it up as well.
You clearly have the best setup to reproduce if any more questions come in, 
therefore would you mind filing a bug with Debian and/or upstream and link it 
here please?

  ProxyDHCP replies on invalid range

Status in dnsmasq package in Ubuntu:

Bug description:
  In Ubuntu 16.04, I've configured dnsmasq to reply on subnet=10.160.37.0/24, 
yet it replies even when it gets an IP on subnet=10.161.254.0/24.
  I've only seen this after clean system restart. If I restart dnsmasq later 
on, it works as expected.
  Maybe when dnsmasq starts, the network isn't up yet, and it incorrectly 
initializes some networking information? I'm using network-manager with DHCP.

[Touch-packages] [Bug 1651044] Re: ProxyDHCP replies on invalid range

2016-12-18 Thread Alkis Georgopoulos

I did another test:
 * I unplugged the network cable so that the ltsp-server didn't have an ip.
 * I ran `service dnsmasq restart`.
 * I plugged the network cable back in.
 * ...and the problem came back again, i.e. dnsmasq replied on invalid range.

This again suggests that it's some kind of wrong initialization when the
network is down while dnsmasq starts.

Using dnsmasq 2.75-1ubuntu0.16.04.1 on i386 architecture.
