With Archanaa's help I've analyzed the problem and filed an issue at https://github.com/Mbed-TLS/mbedtls/issues/7559 .

This problem is most likely to arise if you build with MBEDTLS_PSA_CRYPTO_STORAGE_C enabled but MBEDTLS_PSA_ITS_FILE_C disabled, relying on a native implementation of PSA ITS. As a quick fix, you can add the line
#include "common.h"
at the top of library/psa_crypto_core.h.

Hi,

Can you share your configuration and compiler (including flags and target)? This isn't happening in any of the configurations we test on our CI, but psa_crypto_core.h doesn't include the correct header directly, and maybe the indirect include that makes it work for us is omitted in some configurations.

Library and test code should define MBEDTLS_ALLOW_PRIVATE_ACCESS, but it's missing in some places. We'll fix that, but it would be good to know what configurations make it actually break.

Best regards,

Hello,

In mbedLS v3.4.0, I came across a build error that there are no members for type and flag in psa_core_keyattributes_t structure.

The following functions in psa_crypto_core.h access private members type and flag of psa_core_keyattributes_t structure without the MBEDTLS_PRIBATE() private access.

psa_is_key_slot_occupied()

psa_key_slot_get_flags()

psa_key_slot_set_flags()

psa_key_slot_set_bits_in_flags()

psa_key_slot_clear_bits()

Updating to private access for attribute struct members in psa_crypto_core.h fixed the build errors.
