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),
enable heap-buffer-overflow and use-after-free functions on dpdk.
DPDK ASAN function currently only supports on Linux x86_64.

Here is an example of heap-buffer-overflow bug:
	......
        char *p = rte_zmalloc(NULL, 7, 0);
        p[7] = 'a';
	......

Here is an example of use-after-free bug:
	......
        char *p = rte_zmalloc(NULL, 7, 0);
        rte_free(p);
        *p = 'a';
	......

If you want to use this feature,
you need to add below compilation options when compiling code:
-Dbuildtype=debug -Db_lundef=false -Db_sanitize=address
"-Dbuildtype=debug": Display code information when coredump occurs
in the program.
"-Db_lundef=false": It is enabled by default, and needs to be
disabled when using asan.

Unfortunately, this won't build with some (too smart) compilers.
Can you look at the CI report?
Thanks.

I am trying to solve this issue.If there is no good solution, this test case will be removed.
Thanks.

We are using ASAN on Arm64 without problems, don't know why the patch
shouldn't work there as well.

Google asan cannot support DPDK heap memory detection. This patch adapts to 
google asan so that it can check DPDK heap memory bugs. For each platform,
it is necessary to adapt the base address and do a lot of testing. We don't
have an arm platform here, so we didn't adapt it.

+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::
+
+  Centos8 needs to install libasan separately.
+  If the program uses cmdline, when a memory bug occurs, need to execute the "stty echo" command.
