Abstract
A system performs a registration process for monitoring a respective address range, by: receiving, from an application, a first command to monitor a first address range in a kernel; registering, in the kernel, the first address range; creating a monitoring state window in the kernel, the monitoring state window indicating that the first address range is valid; and providing, to the application, read-only access to the monitoring state window. The system detects, in the kernel based on a previous state of a mapping of virtual addresses to physical addresses, a change associated with a memory mapping of a second address range. The system updates the monitoring state window by invalidating address ranges overlapping with the second address range. Responsive to the first address range being valid, the system bypasses the registration process for the first address range.
