bug when setting the value of Vpb->VolumeLabel

[GoogleCodeExporter]

http://code.google.com/p/dokan/source/browse/trunk/sys/init.c#562

check code

{{{
RtlStringCchCopyW(diskDeviceObject->Vpb->VolumeLabel, 
sizeof(diskDeviceObject->Vpb->VolumeLabel) / sizeof(WCHAR), VOLUME_LABEL);
}}}

I think you need to replace the code. Something like

{{{
diskDeviceObject->Vpb->VolumeLabel = ExAllocatePool(diskDeviceObject->Vpb-
>VolumeLabelLength);
RtlStringCchCopyW(diskDeviceObject->Vpb->VolumeLabel, diskDeviceObject-
>Vpb->VolumeLabelLength / sizeof(WCHAR), VOLUME_LABEL);
}}}

or

{{{
diskDeviceObject->Vpb->VolumeLabel = ExAllocatePool(diskDeviceObject->Vpb-
>VolumeLabelLength);
RtlStringCchCopyW(diskDeviceObject->Vpb->VolumeLabel, sizeof(VOLUME_LABEL) 
/ sizeof(WCHAR), VOLUME_LABEL);
}}}

or read-only

{{{
vpb->VolumeLabelLength = sizeof(VOLUME_LABEL);
vpb->VolumeLabel = VOLUME_LABEL;
}}}

here is the same

I looked up the definition of VPB. I was mistaken. Sorry.
