Public bug reported: A bug exists in ifupdown which incorrectly identifies Infiniband-capable interfaces running in Ethernet mode as Infiniband interfaces. This causes the creation of VLANs to fail with an error such as:
/bin/sh: 1: cannot create /sys/class/net/eth0/create_child: Permission denied The defect appears to be fixed upstream in Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=857976 However, it doesn't look like Ubuntu 18.04 includes the fix, as the version of ifupdown is 0.8.17ubuntu1.1, while upstream fixed it 0.8.27. By shipping 18.04 without this fix, all users of such NICs (such as Mellanox ConnectX-3 series) are unable to create VLANs with ifupdown. Therefore, I request that this fix be implemented as a bugfix in 18.04. ** Affects: ifupdown (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1806153 Title: ifupdown cannot create VLAN subinterface on an Infiniband-capable port running in Ethernet mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1806153/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
