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 ...
When an interrupt happens in protected (32-bit) mode, the x86 CPU will look in the TSS for SS0 and ESP0 and load their values into SS and ESP respectively. 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.
Kernel Patch Protection is the technology that enforces these restrictions. It works by periodically checking to make sure that protected system structures in the kernel have not been modified. If a modification is detected, then Windows will initiate a bug check and shut down the system, [6] [8] with a blue screen and/or reboot. The ...
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 ...
Nouveau was accepted in version 2.6.33 of the kernel, released on December 10, 2009. Kernel-based mode setting is not only supported by the nouveau driver, it is required. [8] Wayland compositors (e.g. Weston) and kmscon depend on kernel mode setting via ioctl.
The mechanism is first described in Intel manuals and datasheets for the Intel 80286 CPU, which was introduced in 1983; it is also described in section 9.8.13 in the Intel 80386 programmer's reference manual from 1986. A general protection fault is implemented as an interrupt (vector number 13 (0Dh)).
Microsoft Structured Exception Handling is the native exception handling mechanism for Windows and a forerunner technology to Vectored Exception Handling (VEH). [1] It features the finally mechanism not present in standard C++ exceptions (but present in most imperative languages introduced later).
Advanced services include features beyond the kernel like the Windows registry, shutdown/restart the system (or abort), start/stop/create a Windows service, manage user accounts. These functions reside in advapi32.dll and advapires32.dll on 32-bit Windows.
