From 92ea9cd8ab5574b059078a8279eaccbc4a0c1e5d Mon Sep 17 00:00:00 2001 From: Bartosz Nitka Date: Sat, 31 May 2025 14:27:02 +0200 Subject: [PATCH] Ability to run linux tests with AddressSanitizer (#1651) * Ability to run linux tests with AddressSanitizer This makes it possible to compile and run the tests with Address Sanitizer (ASAN) [1]. The command is: ``` make -f custom.mk clean; ASAN=1 make -f custom.mk && ./build/win_main -runUnitTests 2 ``` Building without ASAN works without change. Address Sanitizer saves a lot of time debugging memory issues, for example for a bug where we index in an array with negative index it gives this nice error message: ``` ================================================================= ==2532658==ERROR: AddressSanitizer: global-buffer-overflow on address 0x5642389c5e37 at pc 0x564237e67492 bp 0x7fff17726e50 sp 0x7fff17726e40 READ of size 1 at 0x5642389c5e37 thread T0 #0 0x564237e67491 in CHANNEL_GetType src/new_cfg.c:427 #1 0x564237dfc933 in TuyaMCU_ApplyMapping src/driver/drv_tuyaMCU.c:1126 #2 0x564237dff92f in TuyaMCU_ParseStateMessage src/driver/drv_tuyaMCU.c:1632 #3 0x564237e019fa in TuyaMCU_ProcessIncoming src/driver/drv_tuyaMCU.c:1977 #4 0x564237e027ee in TuyaMCU_RunReceive src/driver/drv_tuyaMCU.c:2178 #5 0x564237e02dc2 in TuyaMCU_RunFrame src/driver/drv_tuyaMCU.c:2335 #6 0x564237dd2ce6 in DRV_RunQuickTick src/driver/drv_main.c:536 #7 0x564237ec4037 in QuickTick src/user_main.c:946 #8 0x564237eca8a5 in Sim_RunFrame src/win_main.c:106 #9 0x564237eca993 in Sim_RunFrames src/win_main.c:134 #10 0x564237ebce4a in Test_TuyaMCU_Basic src/selftest/selftest_tuyaMCU.c:369 #11 0x564237ecab1f in Win_DoUnitTests src/win_main.c:194 #12 0x564237ecba57 in main src/win_main.c:535 #13 0x7fb55312ed8f in __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58 #14 0x7fb55312ee3f in __libc_start_main_impl ../csu/libc-start.c:392 #15 0x564237cb16b4 in _start (/home/niteria/tmp/broken-realloc/OpenBK7231T_App/build/win_main+0xcf6b4) 0x5642389c5e37 is located 51 bytes to the right of global variable 'stat_deduper_culled_tooFast' defined in 'src/mqtt/new_mqtt_deduper.c:40:12' (0x5642389c5e00) of size 4 0x5642389c5e37 is located 9 bytes to the left of global variable 'g_mutex' defined in 'src/mqtt/new_mqtt_deduper.c:42:26' (0x5642389c5e40) of size 4 SUMMARY: AddressSanitizer: global-buffer-overflow src/new_cfg.c:427 in CHANNEL_GetType Shadow bytes around the buggy address: 0x0ac8c7130b70: 04 f9 f9 f9 f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 0x0ac8c7130b80: 00 f9 f9 f9 f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 0x0ac8c7130b90: 04 f9 f9 f9 f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 0x0ac8c7130ba0: 00 00 00 00 00 00 00 00 00 00 f9 f9 f9 f9 f9 f9 0x0ac8c7130bb0: 04 f9 f9 f9 f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 =>0x0ac8c7130bc0: 04 f9 f9 f9 f9 f9[f9]f9 04 f9 f9 f9 f9 f9 f9 f9 0x0ac8c7130bd0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0ac8c7130be0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0ac8c7130bf0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0ac8c7130c00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0ac8c7130c10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb Shadow gap: cc ==2532658==ABORTING ``` [1] https://github.com/google/sanitizers/wiki/addresssanitizer * disable tests broken on linux * add a suppression file for known leaks * attempt at adding an ASAN workflow * fix autogen * Update workflow.yaml --------- Co-authored-by: openshwprojects <85486843+openshwprojects@users.noreply.github.com> --- .github/workflows/workflow.yaml | 20 ++++++++++++++++++++ custom.mk | 10 +++++++++- platforms/linux/asan.suppressions | 4 ++++ src/selftest/selftest_energyMeter.c | 3 +++ src/win_main.c | 3 +++ 5 files changed, 39 insertions(+), 1 deletion(-) create mode 100644 platforms/linux/asan.suppressions diff --git a/.github/workflows/workflow.yaml b/.github/workflows/workflow.yaml index 6ef8611fc..079eec38c 100644 --- a/.github/workflows/workflow.yaml +++ b/.github/workflows/workflow.yaml @@ -103,6 +103,26 @@ jobs: name: ${{ env.APP_NAME }}_${{ needs.refs.outputs.version }}_sim path: output/${{ needs.refs.outputs.version }}/obkSimulator_${{ needs.refs.outputs.version }}.zip + build_asan: + name: Build Linux Simulator and Run Tests With Address Sanitizer + needs: refs + runs-on: ubuntu-22.04 + + steps: + -
