           Summary: libfsimage overwrites stack if operating on ffs/ufs with
                    blocksize > 8k
           Product: Xen
           Version: 3.0 (general)
          Platform: x86-64
        OS/Version: Linux-2.6
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: fjo-xen@xxxxxxxx


Symptom: pygrub shows undefined behaviour if guest is a NetBSD with a ffs (ufs)
root filesystem with a blocksize greater than 8k.

Reason: FSYS_BUF in libfsimage is too small

Fix: see my patch
