The thing is, I rely on 'ip' a lot. So, not wanting to have to rely on
code I knew was buggy, and how it was buggy, I apt-get sourced it, fixed
it, and installed it on all my machines. I have now no machines with
that particular bug left. My hunch is that when using network namespaces

By the way, the bug was fixed already:
http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/commit/?id=a1b4a274d4917be06b3060d3c8e95aba5c92a9a9
So by upgrading to ip version 4.5 this should be fixed.

I think that that would do the same.

I found the bug: in the package iproute2 version 2-4.3, in the file
ip/ipnetns.c, line 175 must read:
c = malloc(sizeof(*c) + strlen(name) + 1);
instead of:
c = malloc(sizeof(*c) + strlen(name));
** Changed in: iproute2 (Ubuntu)
Status: Expired => In Progress

I have no idea if or whether the 16.10 and 16.04 versions are somehow
the same. I'll see if I can write a script to reproduce the bug (which I
forgot to post: this causes a segfault).
