Problem during test_suite generation while cross-compiling on version 3.6.2

by Francois Mace

Hello Everybody, I am trying to migrate my cross-compilation setup from version 2.28.9 to version 3.6.2. I use a Makefile based approach for compilation. Everything seems to work fine up to the point where the compilation process reaches the test_suite data generation Gen suites/test_suite_psa_crypto_generate_key.generated.data suites/test_suite_psa_crypto_low_hash.generated.data suites/test_suite_psa_crypto_not_supported.generated.data suites/test_suite_psa_crypto_op_fail.generated.data suites/test_suite_psa_crypto_storage_format.current.data suites/test_suite_psa_crypto_storage_format.v0.data At that point it seems that the python based tools attempts to execute a temp executable (generated for my cross-compilation target ?) which fails. The traceback obtained is the following: Traceback (most recent call last): File "../framework/scripts/generate_psa_tests.py", line 849, in <module> test_data_generation.main(sys.argv[1:], __doc__, PSATestGenerator) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_data_generation.py", line 224, in main generator.generate_target(target) File "../framework/scripts/generate_psa_tests.py", line 845, in generate_target super().generate_target(name, self.info) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_data_generation.py", line 177, in generate_target self.write_test_data_file(name, test_cases) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_data_generation.py", line 164, in write_test_data_file test_case.write_data_file(filename, test_cases) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_case.py", line 88, in write_data_file for tc in test_cases: File "../framework/scripts/generate_psa_tests.py", line 694, in all_test_cases if key.location_value() != 0: File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/psa_storage.py", line 186, in location_value return self.lifetime.value() >> 8 File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/psa_storage.py", line 89, in value self.update_cache() File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/psa_storage.py", line 67, in update_cache include_path=includes) #type: List[str] File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/c_build_helper.py", line 158, in get_c_expression_values output = subprocess.check_output([exe_name]) File "/usr/lib/python3.7/subprocess.py", line 395, in check_output **kwargs).stdout File "/usr/lib/python3.7/subprocess.py", line 472, in run with Popen(*popenargs, **kwargs) as process: File "/usr/lib/python3.7/subprocess.py", line 775, in __init__ restore_signals, start_new_session) File "/usr/lib/python3.7/subprocess.py", line 1522, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) OSError: [Errno 8] Exec format error: '/tmp/tmp--m95sjmdw' make[2]: *** [Makefile:127: generated_psa_test_data] Error 1 make[2] : on quitte le répertoire « /home/dev/test/mbed-TLS_3.6.2/tests » make[1]: *** [Makefile:35: tests] Error 2 make[1] : on quitte le répertoire « /home/dev/test/mbed-TLS_3.6.2 » make: *** [test.make:152: all] Error 2 Looking at the format of the generated tmp executable, it seems it is generated for my cross-compilation target, it therefore cannot be executed in my compilation environment. I would like to be able to generate the test and test data in order to be able to execute them on my compilation target, which is what I used to do with the previously integrated version of the library. Is there something I am missing in my compilation? am I missing a specific setup variable in my Makefile? Thanks for your feedback. Best regards, Francois

Different performance from 2.6.2 to 3.6.2 for https file upload

by Stefano Tebaldi

Hello, I recently updated mbedTLS library version 2.6.2 to 3.6.2. I am using the library to add https to Mongoose web server on a STM32H753 with FreeRTOS + LWIP. 2.6.2 was generated in a IAR project using STMCubeMX. What I am noticing is that file transfer performance has gotten much worse. With version 2.6.2 it took a few minutes to transfer a file of around 33 MB, now with version 3.6.2 it takes around 15 min. What could this depend on? Attached is the configuration used for the two versions. The certificate for https is EC curve secp256r1. Thank you

[Mbed-tls-announce] Mbed TLS 4.0/TF-PSA Crypto 1.0 release timeline

by Janos Follath via Mbed-tls-announce

Dear Mbed TLS and PSA Crypto users, We would like to update you on the release timeline for Mbed TLS 4.0/TF-PSACrypto1.0 release. As a reminder, the key objectives of the release are a separate TF-PSA Crypto repo., PSA Crypto becoming the de facto Crypto API and Mbed TLS using PSA Crypto APIs as the crypto API by default. While TF-PSA Crypto repository is now available, the remaining effort to be ready for the release is more than we originally planned for. Based on remaining effort estimates, we plan to make Mbed TLS 4.0-Beta and TF-PSA Crypto 1.0-Beta release around end of June. The Mbed TLS 4.0, and TF-PSA Crypto 1.0 release is expected around end of September. We don’t expect users to integrate the Beta release. Beta is aimed to pipeclean the separate Mbed TLS and TF-PSA Crypto release process and get any early feedback. The release in September is expected to be integrated by users to their projects. We wanted to provide these revised release dates so that the users can plan accordingly. In the meantime, bug fixes and security fixes will continue to be provided via. Mbed TLS 3.6.x LTS releases. Thanks, Mbed TLS/PSA Crypto Maintainers. -- Mbed-tls-announce mailing list -- mbed-tls-announce(a)lists.trustedfirmware.org To unsubscribe send an email to mbed-tls-announce-leave(a)lists.trustedfirmware.org
