wolfssh_template / wolfssh_echoserver don't build

[keredson]

to replicate:

$ idf.py --version
ESP-IDF v5.2.1
$ idf.py create-project-from-example "wolfssl/wolfssh^1.4.15-stable-preview6:wolfssh_template"
[...]
$ cd wolfssh_template/
$ idf.py build
[...]
/tmp/wolfssh_template/managed_components/wolfssl__wolfssl/wolfssl/wolfcrypt/port/Espressif/esp32-crypt.h:890:10: error: #error "ESP32_CRYPT_HASH_SHA256 not supported on wolfSSL at this time"
  890 |         #error "ESP32_CRYPT_HASH_SHA256 not supported on wolfSSL at this time"
      |          ^~~~~
ninja: build stopped: subcommand failed.

same error for wolfssh_echoserver. this is on an esp32.

workaround:

1. move managed_components/wolfssl__wolfssl to components/wolfssl__wolfssl.
2. in ./components/wolfssl__wolfssl/include/user_settings.h, add the following inside #if defined(CONFIG_IDF_TARGET_ESP32):

#define NO_WOLFSSL_ESP32_CRYPT_HASH_SHA256

this leads to a bunch of sha244 related build errors, so
3. comment out #define WOLFSSL_SHA224 in that same file.

and it works.

Hi @keredson

Thanks for this report. Could you tell us a bit about your project using wolfSSH?

I've requested a review of this issue by our engineers.

Hi @keredson and @embhorn

I've been able to reproduce this problem. The issue was related to concurrent SHA HW/SW interleave calculations and fixed in post 5.7.0 release in wolfSSL/wolfssl#7505.

As an interim solution:

• rename wolfssh_template/managed_components to wolfssh_template/components
• edit the CMakeLists.txt in wolfssh_template/components/wolfssl__wolfssl. Uncomment and set WOLFSSL_ROOT:

# Optionally set your source to wolfSSL in your project CMakeLists.txt like this:
set(WOLFSSL_ROOT "/mnt/c/workspace/wolfssl-gojimmypi-pr" )

Set the WOLFSSL_ROOT to the fully qualified path of a local, fresh clone of wolfssl.

I will update the published wolfSSL Managed Component this week.

Hi @keredson

I see you've already closed this issue. Not sure if perhaps you saw some of my work in progress at the Expressif Registry.

I've updated the published components as noted in #699

wolfSSH: https://components.espressif.com/components/wolfssl/wolfssh/versions/1.4.17-preview1m5

and

wolfSSL: https://components.espressif.com/components/wolfssl/wolfssl/versions/5.7.1-preview2d?language=en

I believe the examples should be working much better now. Please take it for a test drive and let me know how it goes.

The updated (preview) echoserver can be found here:

https://components.espressif.com/components/wolfssl/wolfssh/versions/1.4.17-preview1m5/examples/wolfssh_echoserver

idf.py create-project-from-example "wolfssl/wolfssh^1.4.17-preview1m5:wolfssh_echoserver"

Thank you.
