CORRUPT HEAP after reconnect

Posted: Wed Oct 12, 2022 12:30 am
by marclee
Equipment:
ESP32-S2-WROVER with SDK ESP-IDF v5.0-beta1-641-gc321739074

Configuration:
WiFi in mode WIFI_MODE_APSTA
Heap corruption detection = Comprehensive
authmode of ESP-AP = WIFI_AUTH_WPA2_PSK

The Problem:
heap corruption after reconnect

Action:
- Smartphone connects to ESP32-AP (channel 1)
- ESP32 connects to external accesspoint (channel 3 .. 11)
- Smartphone is not capable to switch channel during a connection, so it disconnets
- The ESP32 doesn't recognise the disconnect
- The smartphone connects again to the ESP32-AP
-> CORRUPT HEAP: Invalid data at 0x3ffdd4a0. Expected 0xfefefefe got 0x00000000

The problem occurs if authmode of ESP32-AP is WIFI_AUTH_WPA2_PSK.
The problem doesn't occur if authmode of ESP32-AP is WIFI_AUTH_OPEN.

I tested with ESP32-S2-WROVER and ESP32-S3-WROOM-1-N8R8 and got similar results.
I tested with PSRAM enabled and disabled and got similar results.

The problem doesn't occur always.

The original application is much more complex but I reduced the code to the relevant functions. According to the documentation "Expected 0xfefefefe got 0x..." indicates the app has a use-after-free bug. As there is no dynamic allocation in the application code, I suppose there is a bug somewhere else in the IDE.

Fyi, you may have a quicker answer if you file this as a Github issue.

Thank you for the hint. I have just posted the issue at github: https://github.com/espressif/esp-idf/issues/9973

Can anybody confirm that bug?

Have you run the backtrace decoder (`xtensa-esp32-elf-addr2line.exe`) on the backtrace to see what functions are involved in the corruption? That might help provide some clues.

Is there any documentation about "backtrace decoder"? We use Linux.

Just search for `xtensa-esp32-elf-addr2line`. The documentation doesn't say that it's specific to Windows, but I don't think it is automatically added to your PATH. Check under the tools in your ESP-IDF installation.

Now I understand what you mean. Address decoding has always been activated and usually it works. But in this case it does not seem to work.

The manual execution of the command doesn't work either? I've seen many cases where the console doesn't decode but the command will. If you haven't tried manually executing the decode, give it a try!

I got the back trace, not from the same application, but it's the same error.
