I'm looking for some help on kernel programming. I want to modify the registers of a process when it returns from kernel-land, just after calling a syscall. I have read that user-land registers are stored on the kernel stack before the syscall is called so I tried to change the value of what must be the saved %ebx in the kernel stack at %esp+8 but I don't get the result I'd like... looks like the modification doesn't work but I don't get any error :( Is there a way to contact you to send my exemple code ? Bye ! Hi !
