| H A D | nmdm.c | diff b3f7f76b Tue Sep 09 23:44:15 MDT 2014 Peter Grehan <grehan@FreeBSD.org> Fix issue with nmdm and leading zeros in device name. The nmdm code enforces a number between the 'nmdm' and 'A|B' portions of the device name. This is then used as a unit number, and sprintf'd back into the tty name. If leading zeros were used in the name, the created device name is different than the string used for the clone-open (e.g. /dev/nmdm0001A will result in /dev/nmdm1A). Since unit numbers are no longer required with the updated tty code, there seems to be no reason to force the string to be a number. The fix is to allow an arbitrary string between 'nmdm' and 'A|B', within the constraints of devfs names. This allows all existing user of numeric strings to continue to work, and also allows more meaningful names to be used, such as bhyve VM names. Tested on amd64, i386 and ppc64.
