+Memory error detect standard tool - AddressSanitizer(ASan)
+==========================================================
+
+AddressSanitizer (ASan) is a google memory error detect
+standard tool. It could help to detect use-after-free and
+{heap,stack,global}-buffer overflow bugs in C/C++ programs,
+print detailed error information when error happens, large
+improve debug efficiency.
+
+By referring to its implementation algorithm
+(https://github.com/google/sanitizers/wiki/AddressSanitizerAlgorithm),
+enabled heap-buffer-overflow and use-after-free functions on DPDK.
+DPDK ASan function currently only supports on Linux x86_64.
+
+AddressSanitizer is a part of LLVM (3.1+) and GCC (4.8+).
+
+DPDK ASan functionality is currently only supported Linux x86_64.
+Support other platforms, need to define ASAN_SHADOW_OFFSET value
+according to google ASan document.
+
+Example heap-buffer-overflow error
+----------------------------------
+
+Following error was reported when ASan was enabled::
+
+    Applied 9 bytes of memory, but accessed the 10th byte of memory,
+    so heap-buffer-overflow appeared.
+
+Below code results in this error::
+
+    Add code to helloworld:
+    char *p = rte_zmalloc(NULL, 9, 0);
+    if (!p) {
+        printf("rte_zmalloc error.");
+        return -1;
+    }
+    p[9] = 'a';
+
+The error log::
+
+    ==369953==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x7fb17f465809 at pc 0x5652e6707b84 bp 0x7ffea70eea20 sp 0x7ffea70eea10 WRITE of size 1 at 0x7fb17f465809 thread T0

+Example use-after-free error
+----------------------------
+
+Following error was reported when ASan was enabled::
+
+    Applied for 9 bytes of memory, and accessed the first byte after
+    released, so heap-use-after-free appeared.
+

+    SUMMARY: AddressSanitizer: heap-use-after-free ../examples/helloworld/main.c:48 in main
+
+Usage
+-----
+
+meson build
+^^^^^^^^^^^
+
+To enable ASan in meson build system, use following meson build command:
+
+Example usage::
+
+ meson build -Dbuildtype=debug -Db_lundef=false -Db_sanitize=address
+ ninja -C build
+
+.. Note::
+
+  a) Some of the features of ASan (for example, 'Display memory application location, currently
+     displayed as a wild pointer') are not currently supported by DPDK's implementation.
+  b) DPDK test has been completed in ubuntu18.04/ubuntu20.04/redhat8.3. Centos needs to install
+     libasan separately.
+  c) If the program uses cmdline, when a memory bug occurs, need to execute the "stty echo" command.
