[tpm2] TPM2 PKCS11 intergration error for Openstack Barbican

Hello Everyone,

This is Nitesh. I'm working on integrating TPM as a backend to store keys for Openstack Barbican project.

Existing PKCS11 Crytpo Plugin procedure to generate the hmac and mkek is https://docs.openstack.org/barbican/stein/install/barbican-backend.html#pkcs-11-crypto-plugin.

I'm trying to integrate TPM as backend with TPM2-PKCS11 package for Openstack Barbican. https://github.com/tpm2-software/tpm2-pkcs11

When i try to run "barbican-manage  hsm gen_hmac --library-path /usr/lib64/pkcs11/libtpm2_pkcs11.so.0 --passphrase stack --slot-id 1 --label my_hmac_label"
ERROR: cannot load library '/usr/lib64/pkcs11/libtpm2_pkcs11.so.0': /usr/lib64/libtss2-fapi.so.1: undefined symbol: Esys_TRSess_GetAuthRequired.  Additionally, ctypes.util.find_library() did not manage to locate a library called '/usr/lib64/pkcs11/libtpm2_pkcs11.so.0'

I don't know why i'm getting the error message.

Did i miss any package or any other configuration is required ?

I've debugged the error  to some extent.
Actually "Esys_TRSess_SetAttributes" is a function which is giving the error at https://github.com/tpm2-software/tpm2-tss/blob/master/src/tss2-fapi/fapi_util.c#L2061
But that function defination is actually present in "https://github.com/tpm2-software/tpm2-tss/blob/5c178b2b61a05e1873be30cfeb4629bba5be900d/include/tss2/tss2_esys.h" and "https://github.com/tpm2-software/tpm2-tss/blob/9288970a3e657cdee85d08d3813199ec864de3ad/src/tss2-esys/esys_tr.c"

I see "tss2_esys.h" is not included as a header file in  "https://github.com/tpm2-software/tpm2-tss/blob/master/src/tss2-fapi/fapi_util.c."

Please let me know what i've to do to resolve this issue.
