After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. [8] Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...
The MMU detects the page fault, but the operating system's kernel handles the exception by making the required page accessible in the physical memory or denying an illegal memory access. Valid page faults are common and necessary to increase the amount of memory available to programs in any operating system that uses virtual memory , such as ...
The first implementation of a non-executable stack for Windows (NT 4.0, 2000 and XP) was published by SecureWave via their SecureStack product in 2001, based on the work of PaX [7] [8] Starting with Windows XP Service Pack 2 (2004) and Windows Server 2003 Service Pack 1 (2005), the NX features were implemented for the first time on the x86 ...
The kernel connects the application software to the hardware of a computer. Kernel Patch Protection (KPP), informally known as PatchGuard, is a feature of 64-bit editions of Microsoft Windows that prevents patching the kernel. It was first introduced in 2005 with the x64 editions of Windows Vista and Windows Server 2003 Service Pack 1. [1]
A kernel oops often leads to a kernel panic when the system attempts to use resources that have been lost. Some kernels are configured to panic when many oopses (10,000 by default) have occurred. Some kernels are configured to panic when many oopses (10,000 by default) have occurred.
A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program.
This allows for the kernel to use a different stack than the user program, and also have this stack be unique for each user program. A new feature introduced in the AMD64 extensions is called the Interrupt Stack Table (IST), which also resides in the TSS and contains logical (segment+offset) stack pointers.
Once all the boot and system drivers have been loaded, the kernel starts the session manager (smss.exe), which begins the login process. After the user has successfully logged into the machine, winlogon applies User and Computer Group Policy setting and runs startup programs declared in the Windows Registry and in "Startup" folders.
