Dear List,
I am developing a virtual device driver such that the user can
write to the driver a process' pid and a virtual address, and the
module will use these two values to get the memory contents of the
target process. I am wondering if there is any easy functions that can
fetch user page's data at this virtual address. Thank you!
I have tried get_user but this is not possible because the
modules executing get_user at another process's context. I also tried
to use ptrace_readdata, however, it seems that the file at
/kernel/ptrace.c leaves a function access_process_vm undefined and
also I don't know how to compile the source code of my module with
this file (the linker seaches file in /linux/include by default). I am
wondering if there are any other solutions...
Best,
Fangkai
