Support other platforms, need to define ASAN_SHADOW_OFFSET value according to google ASan document, and configure meson (config/meson.build). 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'; ......
