Method for detecting memory leak based on linux kernel

A method for detecting a memory leak based on Linux kernel, applied to an detection of the memory leak, wherein the memory comprises a plurality of memory pages, wherein a node is created through which return addresses of allocation functions to be called in each of the plurality of memory pages and the number of the memory pages allocated by each of the allocation functions are counted;

• wherein the method comprises steps of:
• Step S1, reading the node, acquiring the return addresses of the allocation functions of each of the plurality of memory pages and the number of the memory pages which are allocated correspondingly by the allocation functions;
• Step S2, after reading of the node, releasing the return addresses of the allocation functions counted by the nodes and the number of the memory pages which are allocated correspondingly by the allocation functions;
• Step S3, reading the node again, acquiring the return address of each of the allocation functions and the number of the memory pages which are allocated correspondingly by the allocation functions;
• Step S4, acquiring the number of the memory pages allocated respectively and correspondingly by the identical allocation function in Step S3 and Step S1, and comparing the number in each case to calculate a difference value;
• if the difference value is a positive value and it monotonically increases, it is determined that the memory leak occurs in the memory pages allocated correspondingly by the allocation functions.
