Initialization Vector (IV) discarded for AES CBC Wrap

[gshaurya18]

Hello,

It looks like the iv is discarded for CKM_AES_CBC wrap implementation; An IV = 0 seems to be always be used, regardless of input. So, as in the example here https://github.com/gshaurya18/aes_cbc_test/blob/main/src/main.rs#L122 performing wrap on the same payload with the same wrapping key but different Initialization vectors yields the same result. Is this expected?

Is the implementation missing to set the blocksize to 16 here https://github.com/softhsm/SoftHSMv2/blob/develop/src/lib/SoftHSM.cpp#L6296, causing us to not copy over any bytes from the input iv https://github.com/softhsm/SoftHSMv2/blob/develop/src/lib/SoftHSM.cpp#L6333?

There also seems to be a similar issue for CKM_DES3_CBC where blocksize is not set to 8 https://github.com/softhsm/SoftHSMv2/blob/develop/src/lib/SoftHSM.cpp#L6295

Steps to reproduce:

• Follow steps in README of a minimal example to reproduce this issue: https://github.com/gshaurya18/aes_cbc_test
