Description

Calling wolf_test_task() fails in the ed25519_test() function when running on ESP32, IDF5.0 with error code -229.

Failure point is in ed25519_verify_msg_final_with_sha(...) (ed25519.c) where ret = ConstantCompare(rcheck, sig, ED25519_SIG_SIZE/2);` returns 255 instead of the expected 0.

Note, it takes about 2 minutes between completing the AES-GCM test and reaching this fault, so the log reports several watchdog events warning the idle task is not running (because the tests are using up all the processor time).

A work around is to comment out HAVE_ED25519 in user_settings.h if ED255519 isn't needed.

Reproduction steps

Created new project, based on hello example, in VisualGDB. Using IDFv5, recent commit from WolfSSL master branch and also v5.5.4.
Calling wolf_test_task() from main.

#include <stdio.h>
#include "sdkconfig.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_chip_info.h"
#include "esp_flash.h"
#include <iostream>

#include <wolfssl/wolfcrypt/settings.h> // make sure this appears before any other wolfSSL headers
#include <wolfcrypt/test/test.h>

using namespace  std;

extern "C" void app_main(void)
{
    printf("Hello world!\n");

  cout << "\n\nWolf tests\n";
  int rc = wolf_test_task();
  cout << "Test result = " << rc << endl;

  
  cout << "Done.";
  
  while (true)
  {
    vTaskDelay(1000 / portTICK_PERIOD_MS);
  }
}

Wait patiently.

Hi @PaulMartinsen ,

Please try defining CURVED25519_SMALL for your ED25519 issues and let us know if it helps.
If not, please attach your full build settings.

[PaulMartinsen]

CURVED25519_SMALL is already defined in user_settings.h. As I mentioned, I used commit d686f0a (last commit on 2022/12/23) and am using VisualGBD with IDFv5.

Hi @PaulMartinsen I noticed you are getting a bunch of watchdog timeouts during your benchmark tests. Note that in a recent sdkconfig.defaults file, the check idle task settings: CONFIG_ESP_TASK_WDT_CHECK_IDLE_TASK_CPU0=n, (the same for CPU1).

I've confirmed a fresh install of wolfssl 5.5.4 (specifically commit 9b513fd6 from 12/28) using ESP-IDF v5 completes the benchmark with success on an ESP32.

If you are certain you are already doing this, then perhaps try deleting these directories and building fresh:

.visualgdb
.vs
build

as well as remove your sdkconfig (backup as needed) to ensure the defaults are loaded.

If you've done all these things and still are having problems, check that the wolfssl in your target components directory is actually v5.5.4. I have several different versions of ESP-IDF installed for two different toolchains, Each of course needs to have its own copy of wolfSSL installed. Here's my esp32 which has the gcc 11.2 installed, and the esp32-8.4 is using the gcc 8.4 toolchain.

Also: check for a duplicate wolfssl in you local project directory. I do have a new CMakeLists.txt (not yet in a PR) that will check and warn on this.

Here's my benchmark output:

Are you using an ESP32-S2, -S3, C3? Try to turn off hardware acceleration to see if that makes a difference.

[PaulMartinsen]

HI @gojimmypi , I discovered this while working on an ESP32-S3 port. When I found the test failed for both the ESP32-S3 and the ESP32 I raised the issue. I'm not sure if I need ED25519, but others might.

For this issue, we could consider only the ESP32 target as WolfSSL doesn't support hardware acceleration on the ESP32-s3 yet. Also when I tried to run without hardware acceleration I got unhandled exceptions. I didn't look too closely as it wasn't important to me at this point.

I'm not using the benchmark example. I'm calling wolf_test_task() from a program based on the hello world example in VisualGDB. Specifically:

#include <stdio.h>
#include "sdkconfig.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_chip_info.h"
#include "esp_flash.h"
#include <iostream>

#include <wolfssl/wolfcrypt/settings.h> // make sure this appears before any other wolfSSL headers
#include <wolfcrypt/test/test.h>

using namespace  std;

extern "C" void app_main(void)
{
    printf("Hello world!\n");

  cout << "\n\nWolf tests\n";
  int rc = wolf_test_task();
  cout << "Test result = " << rc << endl;

  
  cout << "Done.";
  
  while (true)
  {
    vTaskDelay(1000 / portTICK_PERIOD_MS);
  }
}

I compared the user_settings.h you supplied with mine and they are the same.

I loaded the bench mark program into VisualGDB, built against IDF-v5 and programmed it onto an ESP32. The output I got was:

Benchmark complete

This didn't report any errors for the ED25519 benchmark. However, as I mentioned, I am calling wolf_test_task().

@PaulMartinsen ah yes, my mistake: test not benchmark. Also, I believe I had previously stated that all that is needed is some user_settings.h changes. This is incorrect with regards to the current wolfSSL branch. I do however have the needed changes on my Espressif_Multichip branch. Additionally I've also created PR#5956 for you; a minor change to the random.c for the ESP32-S3 and a VisualGDB file for the IDF v5.

If using instead WSL to build & flash:

idf.py set-target esp32s3
idf.py fullclean
idf.py  -b 921600  -p /dev/ttyS8  build flash monitor -b 112000

Here's my most recent change to the end of user_settings.h for the CONFIG_IDF_TARGET_ESP32S3:

#if defined(CONFIG_IDF_TARGET_ESP32C3)
    #define NO_ESP32WROOM32_CRYPT
    #define NO_WOLFSSL_ESP32WROOM32_CRYPT_HASH
    #define NO_WOLFSSL_ESP32WROOM32_CRYPT_AES
    #define NO_WOLFSSL_ESP32WROOM32_CRYPT_RSA_PRI
#elif defined(CONFIG_IDF_TARGET_ESP32S3)
    #define NO_ESP32WROOM32_CRYPT
    #define NO_WOLFSSL_ESP32WROOM32_CRYPT_HASH
    #define NO_WOLFSSL_ESP32WROOM32_CRYPT_AES
    #define NO_WOLFSSL_ESP32WROOM32_CRYPT_RSA_PRI
#elif defined(CONFIG_IDF_TARGET_ESP_OTHER)
   /* other */
#else
  /* default is ESP32-WROOM */
#endif

As you noted, I'm also calling wolf_test_task() in main.c.

It is not super fast at this time without hardware acceleration, but the wolfssl_test is fully functional on my Espressif_Multichip branch. The output includes the changes in #5955 that add git version information to the wolfssl version.h file:

Please confirm once you have the benchmark and tests working on the ESP32 (without any changes). Then let's update the GitHub subject, as it's not really a bug regarding the -S3 capabilities at this time.

I'm looking forward to helping you get full ESP32-S3 support!

Cheers
