Abstract
A method for detecting a memory leak based on Linux kernel, applied to an detection of the memory leak, comprises: reading a node, acquiring the return addresses of the allocation functions of each of the plurality of memory pages and the number of the memory pages thereof; releasing the return addresses of the allocation functions and the number of the memory pages counted by the node; reading the node again, acquiring the return address of each of the allocation functions and the number of the memory pages thereof; comparing the number in each case to calculate a difference value, if the difference value is a positive value and monotonically increases, it's determined that the memory leak occurs in the memory pages allocated correspondingly by the allocation functions. During the detection of the memory leak, the detection method consumes less memory without affecting the efficiency in allocating and releasing the memory.
