Its a signed vs unsigned int problem.

afsint.h and afscbint.h include

 typedef afs_uint32 VolumeId;

which is used throughout the src/vol package for volume ids.
In volser/vos.c and volser/vsprocs.c the volume id variables are
defined as signed 32-bit (afs_int32).

There are also some signed vs unsigned issued in some of the
protocol structures.  I believe the type VolumeId should be
used consistently to define types of volume id variables.

In vldbint.xg:

struct [nu]vldbentry uses afs_uint32 for the volumeId array but
afs_int32 for the cloneId.  Same for VldbUpdateEntry.

VldbListByAttributes uses afs_int32 for the volumeid.

This is not a full examination but I believe it shows where the
problem lies.
