STATUS_FILE_CLOSED returned during IRP_MJ_WRITE

NTFSD
1

Hi all,
I’m trying to roll my own IRP_MJ_READ during IRP_MJ_WRITE dispatch received in my file system filter driver for encryption.
From my IRP_MJ_READ completion routine I receive STATUS_FILE_CLOSED error and after that I receive bug check PFN_LIST_CORRUPT
P1 = 7
P2 = 1487
P3= 1
P4 = 0
Parameter 1
Check Key =7
Any help will be appreciated.

You are not handling the MDL correctly. Are you using non-paged pool? If
so, did you use MmBuildMdlForNonPagedPool instead of MmProbeAndLockPages (or
vice-versa)?

This problem normally occurs because the reference count (or share count) is
wrong on the page in the PFN database (and this normally happens because
drivers do not handle the MDL properly).

Regards,

Tony

Stefan,

In adition to Tony’s advice, if you are processing a paging IO write
request, you should read
from the target file through a paging IO as well, and not through a normal
read. Paging IO is
valid for files which has been already cleaned-up (fs received
IRP_MJ_CLEANUP, HandleCount == 0), in which case normal file IO is no longer
allowed.
