I run 16.04, and I keep daily track of all dist-upgrades. 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.
