Userland: Add LibSystem and funnel all syscalls through it This achieves two things: - Programs can now intentionally perform arbitrary syscalls by calling syscall(). This allows us to work on things like syscall fuzzing. - It restricts the ability of userspace to make syscalls to a single 4KB page of code. In order to call the kernel directly, an attacker must now locate this page and call through it. 2021-02-05 12:16:30 +01:00			`set(SOURCES`

CMake: Make libc.a self-contained Previously, libc.a contained undefined symbols from ssp and libsystem, which caused static compilation to fail. We now generate libc.a with a custom CMake rule that combines all object files from libc, ssp and libsystem to form libc.a Closes #5758. 2021-03-14 21:39:09 +02:00
