Yesterday (3 july 2018) there was an upgrade, and it must have been a kernel upgrade, because my machine had rebooted (which I make it do automatically if needed). From today, the system tests on my project have stopped working (C development). These system tests do the following: using the 'ip' command, they set up several network namespaces, in which I run several executables concurrently, that exchange network messages with each other. The namespaces that use IP have kept on working, while the ones that don't (I'm implementing an ethernet network packet structure of my own) have stopped working. I've done the same tests on my laptop, which is also a 16.04, on which I haven't done the upgrade (and I'm very hesitant to do so now, because this is my bread and butter), and there they work still. --- ApportVersion: 2.20.1-0ubuntu2.18 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: kees 1919 F.... pulseaudio /dev/snd/seq: timidity 1084 F.... timidity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=3ed19ff5-7945-42ac-a22a-9136402798d8 InstallationDate: Installed on 2018-02-06 (148 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release i386 (20160420.1) IwConfig: lo no wireless extensions. enp1s0 no wireless extensions.
