Handshake Fails Server Side error fatal:unexpected_message

by Satya Prakash Prasad

We are testing the HosatAP module integrated with MBedTLS version 2.19.1. But we are receiving an error during the SSL handshake. In Server side we are using hostapd daemon - we see the below error: SSL: SSL_accept:SSLv3/TLS write server done OpenSSL: TX ver=0x0 content_type=256 (TLS header info/) OpenSSL: Message -

JA4, JA4_r etc? Is the "Client Hello" response from the client in the correct format?

MbedTLS (2.25.0) TLS handshake on FreeRTOS - PSA Crypto enabled (SE) but not used during client step 8

by hippolyte.einfalt＠viveris.fr

Greetings, ## The Setup Greetings, ## The Setup I have a RENESAS board that has an integrated crypto processor and uses MbedTLS 2.25.0. I have a SE (secure element) connected to it. I am allowing hardware acceleration and PSA crypto API inside mbedtls_config.h I registered my SE driver before calling psa_crypto_init(). The board connects to a web server and performs TLS handshake with the forced cipher `MBEDTLS_TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256`. ## The issue The handshake fails during the step 8 when generating EC private key for ECDHE exchange. I have tracked the issue through debug and it unfolded as follows inside `ssl_write_client_key_exchange()`: - We enter the PSA crypto code from the pre-processor directives. - We set the key attributes after initializing them to 0. (here usage_flags, algorithm, type and bits field are set but lifetime is still 0 from init at this point, this will count later on) - The next function `psa_generate_key()` fails. ## In depth When inside the `psa_generate_key()` function, we start the key creation inside `psa_start_key_creation()`. But here, when validating the attributes of the key in `psa_validate_key_attributes()`, we are not able to rely on the SE to store the key due to it being volatile (lifetime is still 0), the driver is never called. From there the program keeps going until trying to generate the key with the crypto processor from the board which does not support this type of key and returns unsupported error. ## Main question Since the lifetime is forced to be representing a volatile key and since the driver for the SE is not called except for persistent ones, i cannot do this cryptographic step using the SE. Is the generation of the volatile key at this step meant to be handled by the MbedTLS library (software or hardware alt) and not by the PSA Crypto API (SE) due to the key being volatile ? If not, how is the Se supposed to be called in the handshake and what am i missing ? ## Discussion I can pass the handshake when disabling hardware acceleration and using the software for cryptographic steps, but in this case i am not using the SE for them. Should the SE only be used to store the client certificate for mTLS case ? ## Note I must use the MbedTLS version 2.25.0 since the SE driver I am using relies on this version.

Release all memory held by mbedtls_ssl_context

by Satya Prakash Prasad

Hi, We are writing a client code which can accept or decline connection to the server - so for each connection I understand there is a mbedtls_ssl_context data established. Once the same is closed or not required we need to do deinitialize or free memory allocated to its member variables like - we need to free all memory allocated since we need it back else our application will run out of memory like: os_free(mbed_ctx->handshake); os_free(mbed_ctx->transform_negotiate); os_free(mbed_ctx->session_negotiate); os_free(mbed_ctx->in_buf); os_free(mbed_ctx->out_buf); But there are many member variables which also need to free memory if allocated and assigned to it. Is there a function / method that can free all memory for mbedtls_ssl_context instance variable? Thanks in advance. Regards, Prakash

EAP TLS

by Satya Prakash Prasad

Hi, I am working on an issue related to memory leak in MBedTLS. We have integrated MBedTLS code for below 3rd party HostAPD code integration . https://github.com/prplfoundation/hostap [Hostapd] Please refer to the Hostapd peer code implementation as provided in the link below: https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_exampl… https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_exampl… The main function code snippet is provided below: https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_exampl… if (eap_example_peer_init() < 0 || eap_example_server_init() < 0) return -1; do { printf("---[ server ]--------------------------------\n"); res_s = eap_example_server_step(); printf("---[ peer ]----------------------------------\n"); res_p = eap_example_peer_step(); } while (res_s || res_p); Since we are implementing code for peers hence we have removed the server step. Now we need to keep monitoring for new connections / failed connections and act accordingly we have modified the code to something like below - if (eap_example_peer_init() < 0 || eap_example_server_init() < 0) return -1; do { res_p = eap_example_peer_step(); if (eap_ctx.eapNoResp || eap_ctx.eapFail) { eap_client_peer_deinit(); eap_client_peer_init(); } } while (1); We have modified the loop such that it will keep iterating for new connections and in case of failure, re-initialization is required. Is my understanding correct? The issue I am facing is that the client peer deinit method is not releasing all memory allocated during eap_example_peer_step() function ( I understand while processing the EAP TLS server request). The deinit is purely implemented to deallocate memory initially allocated for a new connection using TLS? void eap_client_peer_deinit(void) { eap_peer_sm_deinit(eap_ctx.eap); eap_peer_unregister_methods(); wpabuf_free(eap_ctx.eapReqData); os_free(eap_ctx.eap_config.identity); os_free(eap_ctx.eap_config.password); os_free(eap_ctx.eap_config.cert.ca_cert); os_free(eap_ctx.eap_config.cert.client_cert); os_free(eap_ctx.eap_config.cert.private_key); } where void eap_peer_sm_deinit(struct eap_sm *sm) { if (sm == NULL) return; eap_deinit_prev_method(sm, "deinit"); eap_sm_abort(sm); if (sm->ssl_ctx2) tls_deinit(sm->ssl_ctx2); tls_deinit(sm->ssl_ctx); eap_peer_erp_free_keys(sm); os_free(sm); } Can you please let me know whether we are deallocating memory correctly? Thanks in advance. Regards, Prakash

Handshake is successful if the intermediate CA is revoked.

by singaravelu Balasubramani

I am checking the certificate revocation with below scenario. I have Root CA, Intermediate CA and device certificate is signed by Intermediate CA. I am makeing chain certificate by combining Root CA, Intermediate CA and this chain certificate is my active CA certificate and loaded this and device certificate to the drive. From client, I am creating client certificate which is signed by same intermeidate CA. Making ssl handshake. Handshake is success as expected. Now i am revoking the intermediate CA and creating the crl which is signed by the Root CA. This crl has the serial number of intermediate CA. Now loading the CRL to the drive and setting the crl in "mbedtls_ssl_conf_ca_chain". Now i am establishing the ssl connection with the same client ceritificate and expecting the ssl handshake failure due to intermediate CA revoked. But i get handshake is success. Is my understanding right about intermediate CA revocation? I did little background debug, and my obervation is During handshake , it goes to static int x509_crt_verify_chain function in mbedtls. Its trying to find the parent using x509_crt_find_parent for the client certificate and get intermediate CA. During this time, parent_is_trusted is set as true. after this x509_crt_verifycrl is called with client certificate (child), intermediate CA (parent) and crl(has the intermediate CA serial number-issued by Root CA). During x509_crt_verifycrl check, it check for CRL issuer with ca subject and return 0, as its not matching. now in x509_crt_verify_chain , /* prepare for next iteration */ ., they are marking child_is_trusted = parent_is_trusted and child = parent, parent = NULL; and while loop continues, in loop, x509_crt_verify_chain checks for child_is_trusted is true and return as 0. But its not checking that intermediate CA is revoked or not. /* Stop here for trusted roots (but not for trusted EE certs) */ if( child_is_trusted ) return( 0 );
