SGX and security modules
Software Guard Extensions (SGX) is a set of security-related instructions for Intel processors; it allows the creation of private regions of memory, called "enclaves". The aim of this feature is to work like an inverted sandbox: instead of protecting the system from malicious code, it protects an application from a compromised kernel hypervisor, or other application. Linux support for SGX has existed out-of-tree for years, and the effort of upstreaming it has reached an impressive version 22 of the patch set. During the upstreaming discussion, the kernel developers discovered that the proposed SGX API did not play nicely with existing security mechanisms, including Linux security modules (LSMs).
