Audited every esp_* PSA driver against its corresponding software driver in
mbedtls/library (psa_crypto_cipher.c, psa_crypto_aead.c, psa_crypto_mac.c,
psa_crypto_hash.c, psa_crypto_ecp.c, psa_crypto_rsa.c) and fixed gaps in
workflow ownership, error-path cleanup, sensitive-data wiping, and BAD_STATE
gating per the PSA Crypto API spec.
esp_aes (cipher): fix padding oracle in cipher_finish by replacing leaky
branches with mbedtls_ct_* primitives; abort wipes the driver-level ctx,
not just the inner mbedtls_aes_context; setup routes errors through abort.
esp_aes_gcm (AEAD): zeroize the 16-byte full_tag scratch; restore the
*output_length = finish_output_size assignment that the SW reference keeps
for future ciphers; NULL the inner ctx pointer after free in abort; gate
update/finish on a live ctx with PSA_ERROR_BAD_STATE.
esp_ecdsa: keep abort-at-exit in the one-shot wrappers so the stack-copy
of the hash (needed for little-endian byte order on HW) is wiped per
PSA spec 6.3.3, drop the over-defensive public-key qx/qy wipes that the
SW driver does not perform.
esp_cmac / esp_hmac_transparent / esp_hmac_opaque (MAC): make abort
idempotent, route setup errors through abort, gate update/finish/
verify_finish on PSA_ERROR_BAD_STATE, wipe M_last and intermediate hmac[]
buffers on completion or HW failure. HMAC opaque gains alg + computed
fields to mirror the SW psa_crypto_mac.c state machine. HMAC transparent
explicitly aborts the inner SHA context before reusing it for the outer
hash.
esp_sha: switch the per-op live indicator to (sha_ctx != NULL) so the
public esp_sha_operation_type_t enum keeps its original ordinal values;
free + NULL sha_ctx on every error path; gate update/finish/clone on a
live ctx; wipe per-algorithm core/parallel-engine scratch buffers
(W[], A[], state) on HW-engine failure.
esp_md5: replace bare memset in abort with mbedtls_platform_zeroize.
esp_rsa_ds: complete() no longer frees sig_buffer (abort owns that);
start() routes failures through abort; asymmetric_decrypt funnels all
cleanup through a single exit: label. RSA-DS utilities wipe the
decrypted-plaintext scratch on v15 / OAEP unpad failure.
Replace nik/nik_valid in wifi_nan_sync_config_t with reset_current_nvs_creds
and use_nvs_for_caching. On NAN start, load the saved own NIK and peer
credentials from NVS (or erase them when reset is requested); generate and
persist a fresh own NIK only when none is valid and caching is enabled.
PASN reuses the SAE module (PWE/crypto and the comeback-token mechanism),
so define CONFIG_SAE whenever SoftAP-SAE or PASN is enabled. This fixes the
undefined references to check_comeback_token()/auth_build_token_req() when
SOFTAP config is disabled.
- fix PASN initiator pmksa_cache_get() usage with the extra argument
- Add attributes to secured NDP frames according to Specs
- Resolve M2 MIC verification failure in secured datapath
