Inserting code from userspace to kernel space

[Bosko Radivojevic]

Hi!

I'm looking for a way to insert code from user space to the kernel
space, but without using kernel module. Actually, we are working on a
system that has to allow end user to change part of code (one or two
functions) that is executed from the kernel space.

For now we have two different kernel modules, one exporting a function
which another module uses. Process of compiling kernel module is quite
ineligible for standard end user (along with the requirement to
support multi platform cross compiling) compared to just cross
compiling a simple code that doesn't use any libraries than libc.

I know this sounds quite weird, but maybe there is a project that can help us ;)

Sincerely,
Bosko
