NMI can be delivered at any time, including when the kernel is in the middle of switching stacks. Using IST for NMI events avoids making assumptions about the previous state of the kernel stack. ESTACK_DB. EXCEPTION_STKSZ (PAGE_SIZE). Used for hardware debug interrupts (interrupt 1) and for software debug interrupts (INT3).Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. So the idea is the following: make the two TLB have different views of the same entry. All pages are marked in the tables (in RAM) as "absent", thus triggering an exception upon access. The kernel traps the exception, and the exception includes some data about the type of access, in particular whether it was for code execution, or not.

Apr 04, 2006 · Hooking the kernel directly ... order) on the kernel stack before it transfers the execution to the appropriate handler. In the case of some exceptions, the CPU may ... Proper exception handling is critical for any application. A key component to that is logging the exceptions to a logging library so that you can record that the exceptions occurred. Please check out our guide to C# Logging Best Practices to learn more on this subject. We suggest logging your exceptions using NLog, Serilog, or log4net.
