Kernel Data StructuresSummary: It is very challenging to verify the integrity of Operating System (OS) kernel data because of its complex layout. In this paper, we address the problem of systematically generating an accurate kernel data definition for OSes without any prior knowledge of the OS ...
Developed OS kernel with process and thread management, following five-state model. Initializes processes, threads, stacks, and relevant kernel data structures. PCB's state field tracks process state for statistics in "Anzen Kernel". - Jasim-BinUmar/Anze
CONFIG_DEBUG_VIRTUAL=y - Enables sanity checks in virtual to page code to prevent certain data corruption. CONFIG_INTEL_IOMMU_DEFAULT_ON=y - Enables IOMMU by default to prevent DMA attacks. [32] CONFIG_GCC_PLUGIN_STRUCTLEAK=y - STRUCTLEAK automatically initializes stack variables to zero to ...
RAMPARSER uses this file to obtain the virtual addresses of many functions and data structures it needs to analyze to correctly model kernel data structures. Parsing System.map is relatively straightforward, but RAMPARSER does needs to accommodate some eccentricities in the format of System.map, ...
[2] Linus didn’t expect the operating system (OS) he wrote for his own use to become multiplatform; as a result, old structures are sometimes loosely typed. Interface-Specific Types Some of the commonly used data types in the kernel have their own typedef statements, thus preventing any ...
Enable full-sized data structures for core CONFIG_BASE_FULL 在内核中使用全尺寸的数据结构.禁用它将使得某些内核的数据结构减小以节约内存,但是将会降低性能 Enable futex support CONFIG_FUTEX 快速用户空间互斥(fast userspace mutexes)可以使线程串行化以避免竞态条件,也提高了响应速度.禁用它将导致内核不能正确的...
In other stacks such as network or USB, the heap is used for service tasks related to the stack, as well as any internal data structures that must be created. Unfortunately, because everything is so configurable it is not possible at this time to determine the exact size of the heap ...

Process and threads’ most significant data structures are living both in user and kernel space, depending on their role and functionality.Here a summary of the most important kernel structures and their role:Kernel StructureDescription _EPROCESS executive process object _KPROCESS kernel process object ...
