           Summary: Linux kernel bug if you specify vif's MAC-address with
                    dashes instead colon character
           Product: Xen
           Version: unspecified
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Guest-OS
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: pekka.panula@xxxxxxxxxxxxx


Xen version is 3.2.1, Dom0 is CentOS 5.2 64-bit.
Guest host is: CentOS 5.2 32-bit paravirtualized

If you specify MAC-address with dashes, eg. character: - , under virtual hosts
configuration, /etc/xen/machine) and boot it. It will say kernel BUG at
net/core/dev.c:3298! and then kernel crashes.

So this is wrong and causes kernel BUG message:
vif = [ "mac=00-16-3e-4b-4a-bd,bridge=br13" ]

Actually this is close to this bug:

But in that case mac -address was correctly formatted but comma was missing
between mac and bridge, but in this case you can crash kernel with formatting
mac-address with dashes.
