WebAbandoned:Hierarchical process management. Multiple approaches:Some L4 kernels retain the model of recursive address-space construc- tion, while seL4 and OKL4 originate mappings from frames. Added:User-level control over kernel memory in seL4, kernel memory quota in Fiasco.OC. Unresolved:Principled, policy-free control of CPU time. WebThis compounds with seL4's confidentiality guarantees. It's also worth mentioning that Spectre is such a threat, in part, because it makes it easier to exploit kernel vulnerabilities by exposing kernel memory. seL4, by nature of being a formally verified microkernel, has nowhere near the attack surface of something like Linux. merlin phone toy
