Se050-PLUG-TRUST-MW empty "axCi_Mutex" implementation and possibly deadlock in NXP code

[grzegorz2]

Hi

I'am using MW version 03.03.00

I found out that openssl plugin uses mutex which has empty implementation in the file "sss/plugin/openssl/engine/src/ax_cryptoIpc.c" is it required to add implementation? Another issue with this mutex is that with proper implementation it can cause deadlock because of the bug in the file "sss/plugin/openssl/engine/src/ax_sssEngine_ecc.c". There is a code like this:

axCi_MutexLock();

if (status != kStatus_SSS_Success) {

return NULL;

}

axCi_MutexUnlock();

mutex is not released in case of error and application will be deadlocked after next function call

Hi @grzegorz2 ,

Actually I didn't find such kind of issue in the latest version of 04.01.01, would you please update the MW on your hands? or is there any reason to stay with the older version? Please kindly refer to https://www.nxp.com/products/security-and-authentication/authentication/edgelock-se051-proven-easy-t... for more details.

Have a great day,
Kan

Hi @Kan_Li 

I downloaded this new version and I don't see these mutexes anymore so I will use it. Thanks for support.

Have a nice day
