Wouldn't there be a risk that a Linux system call would present an argument that happens to look like a capability and not get intercepted if system calls were implemented by just catching the existing invalid-syscall exceptions?
Not if you don't have any capabilities mapped into the address space.
Correct, which would be a reasonable design for a legacy subsystem, it forces each syscall to raise an exception. Silly me for not pointing this out in the first place. Gernot
