I'll submit it once I find a way of making ifconfig echo the name of the interface AFTER the 'name' command, instead of the name of the interface during 'create' command. Example: "ifconfig tap create name blah" would echo "tap0" but should echo "blah". I found the same bug appeared with the 'description' command as well (ifcon= fig tap create description "some description"). The bug is that setifdescr(...) and setifname(...) doesn't copy the 'global namespace' member 'name' onto the 'ifr.ifr_name' member before doing operations. This made me realize a workaround exist. If you manage to run a command which initializes 'ifr.ifr_name' properly before the 'name' or 'description' commands, these would work as expected. Example: 'ifconfig tap create mtu 9000 name mysupertap' I'll keep digging into the source to figure out how to echo the proper interface name now. --=20 You are receiving this mail because: You are the assignee for the bug.=
