Hi,

I am trying to run a DPDK(20.11) application using memory sanitizer. I have taken the patch from upstream branch: https://github.com/DPDK/dpdk/commit/6cc51b1293ceac4a77d4bf7ac91a8bbd59e1f78c

and made a build with -fsanitize=address. The gcc version is: gcc 6.3.0 . But the application doesn't abort whenan invalid memory access is made. starting the application with below:

./dpdk-app -l 2-4 -a 0000:00:05.0 -a 0000:00:06.0 -a 0000:00:07.0 -a 0000:00:08.0 --socket-mem=3072

Note that the hugetablfs is configured and dpdk allocates memory from huge pages and seems like invalid memory access doesn't abort

ex from the application doeing below doesn't abort:

char *p = rte_zmalloc(NULL, 9, 0); rte_free(p); *p = 'a';

Am I missing something here.?

is DPDK ASAN is supposed to be used only in 21.11 release onwards

Thanks for the help,

Bhargav
