Comment 9 for bug 1947099

Hello @Eric.

> What make Bionic more susceptible to this particular problem ? Bionic kernel version in use ? else ?

I believe klibc/ipconfig itself is susceptible to the problem in Bionic and Focal and elsewhere. However, Focal (which uses klibc 2.0.7) uses dhclient for networking initialization instead of ipconfig, therefore I am not really concerned about fixing the ipconfig issue in Focal since it is not causing any noticeable problems.

I have checked the HEAD of the klibc project and it appears that ipconfig is still susceptible to the timeout problem. Sure I can propose the patch upstream if you like - however, even if they accept it I believe we will still need to apply it separately for Bionic because I do not expect that Bionic will receive any major updates for klibc, so it will not get any upstream fixes. It will remain on 2.0.4 as far as I know. It is currently version 2.0.4-9ubuntu2 in Bionic which means we are carrying (2?) Ubuntu-specific patches on top of 2.0.4. I believe this fix can be added as well to produce 2.0.4-9ubuntu3.

I will attempt to upstream this fix to klibc, but I believe the change to Bionic should happen in parallel/independently since the upstream patch will not make its way back to Bionic (which is stuck at 2.0.4, as mentioned above).
