Fwd: Adding custom system calls
yeah it does seems like a homework question.. I remember doing it on KernelVersion: 2.6 by modifying some files including unistd.h writing a wrapper for it and writing the code for it. This included some tweaking inside the /arch subtree of the kernel. my intentions are entirely academic. Currently working on kernelVer: 3.12.14 I am somewhat struggling to comprehend the changes (steep learning curve), if you could guide me on what files to look for, i am sure i can find my way from there. and Thanks Greg. --big fan :) On Thu, Mar 20, 2014 at 11:11 PM, Greg KH <greg@kroah.com> wrote:

That really sounds like a homework question...
Why do you want to do this, and what have you tried to do that has failed?

There's loads of "how to add a syscall to Linux" tutorials out there, what have you tried and what errors have you gotten when following them? greg k-h
