Description Richard W.M. Jones 2012-05-17 16:15:48 UTC
+++ This bug was initially created as a clone of Bug #822490 +++

Description of problem:

Using the virt-ls --checksum option provokes the following

$ virt-ls -lR -a win2003.img --checksum=md5 / > win2003
libguestfs: error: checksum: path: parameter cannot be NULL

The error happens on any guest because of a simple bug in the
program where 'path' is used before it is set:

  if (checksum && is_reg (stat->mode)) {
    csum = guestfs_checksum (g, checksum, path);  <-- used
    if (!csum)
      exit (EXIT_FAILURE);

    output_string (csum);

  path = full_path (dir, name);  <-- set

Version-Release number of selected component (if applicable):

1.16 (RHEL 6.3) and 1.17 (Fedora) both affected.

How reproducible:

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 2 RHEL Product and Program Management 2012-07-10 23:48:45 UTC
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
