At Microsoft we are seeing more and more issues with kernel stack
overflows on W2K. In every failure I have looked at the system has been
processing a create IRP and almost always there is a filter involved
which has called ZwCreateFile; thus causing a recursive create
operation.
To help address this we have created a HOTFIX that adds the
IoCreateFileSpecifyDevivceObjectHint() API to W2K SP4. The KB article
for this is 835281.
As filter developers you should consider modifying your filters to take
advantage of this API when it is present (using
MmGetSystemRoutineAddress). This way if you have a customer which runs
into kernel stack overflow issues, they could apply this hotfix and if
your filter is ready for it, the problem would be resolved.
