Sandboxing in Linux with zero lines of code

What this post added

This post introduces Linux seccomp as a powerful tool for sandboxing applications without writing code. It explains system calls and how seccomp allows applications to declare their intended system call usage to the kernel, with the kernel terminating or signaling violations. The post demonstrates this with a C code example, showing how to prohibit the 'uname' system call and return a custom error code, effectively preventing arbitrary code execution and enhancing security.
