Memory Mapped Files

Hi,

I am writing a filter driver that will encrypt/decrypt the file. The
problem i am facing is when some application uses memory mapped files
like MS Word or Wordpad to read the file. I cannot intercept the read
call for this kind of files, no IRP_MJ_READ for this kinda files. Is
there something special i have to do for this kind of memory mapped
files.

Thanks and Regards,
Lokanadham R

To perform memory file mapping system need to read file data from hdd into
memory and you can see those read requests with IRP_NOCACHE or IRP_PAGING_IO
or IRP_SYNCHRONOUS_PAGING_IO flags set in Irp->Flags. Only those requests
reads file data into system memory.

The FSD can use the steram file objects( especially the NTFS ) to back the
data segment object.
You must use the FsContext field of the FO.
And as I wrote in the answer to your next post - your design has a flaw.

Misprinted
“steram file objects” - means “stream file objects”

But there is no stream file object created on read operation. NTFS create it
only to perform lazy write. The question was about read operation. But for
write operations you are right.

FSD never performs lazy write. The Cache Manager does this calling
MmFlushSection and the Memory Manager uses the FO which backs the data
segment and this FO is used for any operations on this section(
read/write ).

Can you give some starting point of Memory mapped files in file system mini filter?

Thanks
Lokanadham R

I develop a decompression/decryption filesystem filter driver and have a
problem that I cannot read data from a file from IRP_MJ_READ request which
has IRP_PAGING_IO flag set.
I build own IRP_MJ_READ request and roll it to the underlying driver, I
always get a error 0xc0000000d

What can be the reason, how can I read data from a file?

I understand this, but when IRP’s are rolled down not from paging path all
works fine.

After the file handle is closed (IRP_MJ_CLEANUP has been sent)
non-paging
read/write requests are rejected by file system; paging IO is allowed
for a
file object which handle is closed.

I see, but as far as I understand I should process the situations anyway, if
I just ignore paging io then memory mapped files are not
decrypted/decompressed. Should I just perform pass through in case I get
read error or does it has something with the problem being discussed in
another “Memory Mapped Files to read” topic?]

Thank you,
Roman
