In the hw_ncipher.c module in crypto/engine there are mutex callbacks that return 1 on success and 0 on failure (in openssl-engine-0.9.6b). This is the wrong way around. They should return 0 on success and 1 on failure (see vendor_defns/hwcryptohook.h).
Symptoms: 1) I got concurrency problems in the nCipher code when running 20 odd threads doing signing/verification. 2) I added dynamic lock callbacks which caused the nCipher engine to fail to initialise (messages was mutex_init failed). Debugging I found that mutex_init didn't fail - it was succesfull, it just returned the wrong values. Is this correct?
