ABSTRACT:
The invention provides a system and method for tracking memory information associated with dynamically loaded kernel modules with the help of a tracking system. The tracking system defines its own kernel memory allocation functions. Whenever, a dynamic kernel module is loaded/unloaded into/from the kernel space, these newly defined functions are called in response to kernel memory allocation/de-allocation requests from the kernel module. The newly defined functions are responsible for allocating and de-allocating kernel memory, as well as, keeping track of information relating to the kernel memory allocations/de-allocations. The tracked information may be used to identify the source of kernel memory leaks.
