2. AddressSanitizer Smoke Test

2.1. Description

AddressSanitizer (ASan) is a fast memory error detector,it is a widely-used debugging tool to detect memory access errors.

  • AddressSanitizer<https://github.com/google/sanitizers/wiki/AddressSanitizer>
  • It finds use-after-free, various kinds of buffer overruns in dpdk, and print out detailed debug information whenever an error is detected.
  • ASan is integrated with gcc and clang, and use meson option ‘-Db_sanitize=address’ to enable.

2.2. Prerequisites

  1. NIC requires:

    • Intel ethernet cards: 82599/X710/XXV710/XL710/E810,etc

  2. Software:

    dpdk: http://dpdk.org/git/dpdk.
scapy: http://www.secdev.org/projects/scapy/

2.3. Test Case: RX/TX test with ASan enable

  1. Build dpdk with ASan tool, add “-Dbuildtype=debug -Db_lundef=false -Db_sanitize=address” in meson build system could enable ASan tool, such as below:

    CC=gcc meson -Denable_kmods=True -Dlibdir=lib -Dbuildtype=debug -Db_lundef=false -Db_sanitize=address --default-library=static x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc -j 70

  2. Bind NIC port to vfio-pci.

  3. Setup testpmd, check testpmd could launch successfully and don’t have “heap-buffer-overflow”, “use-after-free” memory errors.

  4. Set mac forward mode.

  5. Send packet and check testpmd forward packet successfully.
