Bug Description

Binary package hint: vde2

From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572261: "slirpvde leaks over 1600 bytes per packet received, even tiny ones like pings. This makes it practically unusable for a production system in the current state."

It was fixed upstream in vde2 (2.3.1-1).

Thanks for reporting this bug. It should be fixed in quantal as it has a newer version. The fix should be backported to precise and SRUd.

(once someone has accepted the nominations for lucid..precise, the main status can be set to fix released)

To SRU these fixes to lucid through precise, we'll need to have an SRU justification including a test case.

Can someone provide a detailed set of steps to test the presence of this fix? Once that's provided, I'll complete the SRU justification and upload the fix for all past supported releases.

I've tried to reproduce this in lucid by using a vde_switch, slirpvde, a vde_plug2tap to tap0 with tap0 at 10.0.2.8, then doing 'nc -l 10.0.2.8 9999' in one window and 'echo hi | nc 10.0.2.8 9999' in another window. The VmSize of the slirpvde task did not go up.

Can someone please post a script to reproduce this? We need that in order to be able to verify the fix for SRU.

I originally encountered the issue when I was attempting to create a VDE virtual network for use with VirtualBox, as described here: http://www.virtualbox.org/manual/ch06.html#network_vde. Hope that is helpful.

Tried a bit longer to reproduce this with various setups, but could not.

I've set the bug status for Natty and Oneiric to Won't fix (they are EOL), Quantal and later have a fixed version, so it's only Precise and Lucid still having the issue. If anyone feels strongly about this, feel free to provide a testcase and prepare the bug for a SRU, as outlined in https://wiki.ubuntu.com/StableReleaseUpdates

A reminder, it would be great if someone could post a detailed set of reproduction instructions for us to use in SRU justification. Without that, we cannot proceed with the SRU.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
