Hello hackers,
I'm writing a kernel module for my own needs. AFAIK the following
methods could be used:
1) allocate not used system call with help of SYSCALL_MODULE macro
2) allocate proprieatry oid via SYSCTL_OID(OID_AUTO) and write an
appropriate sysctl handler(s)
3) add a file in /dev and use ioctl(2) call
What is a preferable way to control my module?
It depends on what you want to do really. I've used sysctl's for simple debug
modules where I write to the sysctl to have it perform a desired action.
I need to pass some configuration parameters to my module and retrieve a
status back. Interface is quite similar to ptrace(2) syscall. I don't
need to pass large amount of data.
Thanks,
Sergey.
