Is inline assembly required on Linux?

Can any user run an inline build for the current Linux kernel, or does it need special permission?

Inline assembly has nothing to do with the kernel. So the answer is no.

Anyone can write an inline assembly and compile it into a program. It is no different from the compiler-generated code.

As for your comment, no answer is possible due to memory protection . As soon as you try to access memory that is not mapped or not allowed (whether in C or through inline assembly), you will get a seg error.



In other words, the level of protection is not between the C code and the compiler. It is between the compiled code and the operating system.

This way, you cannot damage the kernel with C or inline assembly - unless you have permission to do so.
