Summary
| Description |
English: Kernel page-table isolation
Русский: Сейчас в операционных системах один набор страниц для каждого процесса. В KPTI (Kernel page-table isolation) будет два набора. Во-первых, в режиме ядра набор страниц будет включать страницы и пространства ядра, и пространства пользователя. Во-вторых, в режиме пользователя набор страниц будет включать копию страниц пространства пользователя и минимальный набор обработчиков вызовов и прерываний из пространства ядра. |

Own work Source: (2017-11-15). "KAISER: hiding the kernel from user space". LWN.net. "Whereas current systems have a single set of page tables for each process, KAISER implements two. One set is essentially unchanged; it includes both kernel-space and user-space addresses, but it is only used when the system is running in kernel mode. The second "shadow" page table contains a copy of all of the user-space mappings, but leaves out the kernel side. Instead, there is a minimal set of kernel-space mappings that provides the information needed to handle system calls and interrupts, but no more." |
