How to check for reparse point in minifilter

NTFSD

Hi, guys.

I am working on a minifilter driver. I got a problem:
I want to check for reparse point in PRE-create callback routine.

I have tried like this:

  1. Get full path of the target object which was a junction point.
  2. Open it with flag ‘FILE_OPEN_REPARSE_POINT’ set.

But it didnot work. it failed with STATUS_PATH_NOT_FOUND returned.

How to do it?

Thanks in advance!

Alex.

Hi gus, I have fixed it.

The junction was not valid, although the return value of
FSCTL_SET_REPARSE_POINT operation was STATUS_SUCCESS.

Thanks.

Alex.
