reading a file in kernelmode

[David]

Hello,

 

I'm developing a FreeBSD kernel module and I'm searching for a good solution
to open/read/close a file.

My goal is to generate a MD5-Hash of a given file (path).

 

Open-Syscall  seems to be improper.

 

Any ideas/solutions/examples?

Thanks a lot

 

Greetings,

David
