I've read the Linux Kernel Module Programming Guide by Peter Jay Salzman, among other documents, and I have the following question: I'd like to know if it's possible to take a program developed in C (in this case OpenSIPs, which is a SIP Proxy Server) and turn it into a kernel module (I know "to turn it" is probably not the right expression, what I mean is if I could modify it somehow so that it can be loaded as a kernel module) ? As far as I've understand, kernel modules are developed for drivers or to do some modifications to system calls, but I like to know if it's possible to do what I stated earlier. Thanks, Luis Morales. -------------- next part -------------- An HTML attachment was scrubbed...

As you can't use the usual user space libraries in the kernel, it might take quite some time to port a user space program to the linux kernel API. And I guess it wouldn't be a good idea from a security POV, as you don't have things like memory protection in kernel space.
