[Pkg-xen-devel] Bug#671750: Configuration of domain save/restore broken

Package: xen-utils-common
Version: 4.1.2-5
Severity: grave

Hi,

Between 4.1.2-3 and 4.1.2-5, the sanity checks on the variables
defined in /etc/default/xendomains (XENDOMAINS_SAVE,
XENDOMAINS_RESTORE, etc.) was lost. I can't check exactly when because
there's no Vcs defined for this package.

4.1.2-3 had in /etc/init.d/xendomains for restore:
    if [ "$XENDOMAINS_RESTORE" = "true" ] &&
       contains_something "$XENDOMAINS_SAVE"
    then ?

 and for rdnames:
    if ! contains_something "$XENDOMAINS_AUTO"
    then
        return
    fi
 etc.

4.1.2-5 has unconditionally for start restore:
   for file in $XENDOMAINS_SAVE/*; do
    if [ -f $file ] ; then
     ?

 and for stop_save:

  while read id name rest; do
    log_action_begin_msg "Saving Xen domain $name ($id)"
    mkdir -p "$XENDOMAINS_SAVE"

Both these break with an empty XENDOMAINS_SAVE, even though this is
still documented to work.

Furthermore, the XENDOMAINS_AUTO setting is even more broken: when set
to empty (per the docs), it is again not checked and leads to this
init script sending random files to Xen (hence the high severity):
