AFSVolPartitionInfo and AFSVolPartitionInfo64 (vos partinfo) do not
properly initialize their reply buffers. This leaks the contents of
volserver memory over the wire:
AFSVolPartitionInfo (struct diskPartition)
- up to 24 bytes in member name (32-'/vicepa\0'))
- up to 12 bytes in member devName (32-'/vicepa/Lock/vicepa\0'))
AFSVolPartitionInfo64 (struct diskPartition64)
- up to 248 bytes in member name (256-'/vicepa\0'))
- up to 236 bytes in member devName (256-'/vicepa/Lock/vicepa\0')
Initialize the output buffers.
