A security is one of hot topic around Linux ecosystem since Heartbleed in 2014. Many security features were introduced into Linux kernel, for example, KASLR (Kernel Address Space Location Randomization), KPTI (Kernel Page Table Isolation), and so on. On the other hand, these feature makes it difficult to investigate trouble when problem happens to the system. Basically security feature hides kernel information from the attacker for the security, while it also hides the information from those who are trying to find out a root cause of problems. In this presentation, I'll explain kernel security feature and an effort to overcome the problem of Linux kernel crash dump mechanism, caused by such a security feature. Also explain hardware encryption feature (AMD SME, Intel MKTME) and how to enable dump feature with them.
