Oops, meant to say a bit more than just that. I verified the problem in Debian unstable, verified that the patch fixed the problem, and forwarded the bug/patch along to debian.
I've also uploaded the patch to Yakkety and put it into the SRU queue for Xenial. Thanks for the report and patch! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ifupdown in Ubuntu. https://bugs.launchpad.net/bugs/1618726 Title: ifup & ifdown crash if multiple interfaces are listed in no-scripts Status in ifupdown package in Ubuntu: Fix Committed Status in ifupdown source package in Xenial: In Progress Bug description: [Impact] ifup and ifupdown segfault if multiple interfaces are listed in no-scripts This is a trivially reproducible crash in ifup/ifdown, with a patch attached. [Test Case] Steps to reproduce: 1) echo no-scripts foo bar >> /etc/network/interfaces 2) ifup baz Expected results: Unknown interface baz Actual results: Segmentation fault (core dumped) It's irrelevant whether the second interface is on the same no-scripts line or separate one. This will crash just the same: echo no-scripts foo >> /etc/network/interfaces echo no-scripts bar >> /etc/network/interfaces [Regression potential] Seems slight. The patch fixes a clear bug in code that is only used to process the no-scripts (and apparently no-auto-down) stanzas.
