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: > On Thu, Mar 20, 2014 at 10:55:42PM +0530, arun kumar wrote: > > How do i add a Custom system call to my Linux Kernel. > > I want to know what files to modify and where to make the entries. > > That really sounds like a homework question... > > Why do you want to do this, and what have you tried to do that has > failed? > -------------- next part -------------- An HTML attachment was scrubbed...

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 ^ permalink raw reply [flat|nested] 5+ messages in thread
