Hi All,
I am developing a FSFD based filespy sample.I want system to popup
verify dialog before user want to open the attached
volume(C:,D:,ie…),so I have to interrupt IRP_MJ_CREATE in FS
filter driver.
First,The FSFD notify USERMODE App when user want to open C:.
Second, USERMODE App call DeviceIoControl with the IOCTL that my
private defined IOCTL(FILESPY_SetOk)if USERMODE App
allow user to open C:.
Now,I have finished the program.It seems that program can work well.
However,User’s opening IE browser’s combo box for link address will make
OS crash after user has installed my FSFD.
The problem is so strange that I can’t understand this case,and I haven’t
finded any way to debug my program.
PLS HELP ME!!!
best regards,
sailing_an
I am pretty suspicious about any scheme that will defer IRP_MJ_CREATE
indefinitely waiting for user input. It may work in limited cases, but
since IRP_MJ_CREATE is inherently synchronous, deferring it can cause a
number of problems, not the least of which big problems for access from
servers, such as the CIFS file server etc.

Why use filespy? The current source is not available, but sfilter is
available with the IFS Kit. Don’t forget that both sfilter and filespy are
passive filters and you are attempting an active filter. Your design needs
to be revisited because this ring zero and ring three interaction is not
good.

Hi,

I am a newbie on FSFD in fact.
Can you give me a good solution?
