OS: Ubuntu 22.04 with fips-updates

Symptom: Use of TPM2 tools fails with error code 0x70001 (e.g., tpm2_clear, tpm2_nvdefine 0x1500018 -C o -s 32). I assume this is an incompatibility between tpm2-tools (5.2-1build1) and the fips OpenSSL package (3.0.5-0ubuntu0.1+Fips2.1).

Example:

tpm2_clear
ERROR:esys_crypto:src/tss2-esys/esys_crypto_ossl.c:412:iesys_cryptossl_hmac_start() ErrorCode (0x00070001) DigestSignInit
ERROR:esys_crypto:src/tss2-esys/esys_crypto.c:185:iesys_crypto_authHmac() Error ErrorCode (0x00070001)
ERROR:esys:src/tss2-esys/esys_iutil.c:1244:iesys_compute_hmac() HMAC error ErrorCode (0x00070001)
ERROR:esys:src/tss2-esys/esys_iutil.c:1354:iesys_gen_auths() Error while computing hmacs ErrorCode (0x00070001)
ERROR:esys:src/tss2-esys/api/Esys_Clear.c:188:Esys_Clear_Async() Error in computation of auth values ErrorCode (0x00070001)
ERROR:esys:src/tss2-esys/api/Esys_Clear.c:74:Esys_Clear() Error in async function ErrorCode (0x00070001)
ERROR: Esys_Clear(0x70001) - esapi:Catch all for all errors not otherwise specified
ERROR: Unable to run tpm2_clear

Steps to reproduce:

  1. Install new Ubuntu Server 22.04
  2. Apply all updates
  3. Attach pro license and enable fips-updates service
  4. Install tpm2-tools
  5. Reboot
  6. Run sudo tpm2_clear

This looks similar to:

#2957

Thank you in advance for considering this issue. Please let me know if I can help troubleshoot further.

Yes, the ERROR originates from an OpenSSL call to DigestSignInit for an HMAC.
I have no clue how in the world this can go fail...
I'm afraid, you'll have to debug, maybe set a breakpoint on DigestSignInit using gdb and see what the call looks like and why it fails...

Options: Add option to allow usage of password session.
5248d1e 
For authentication of an object always an HMAC session was used.
For an unsalted session an openssl HMAC key with the size of the
auth value was created. This caused problems with the OpenSSL
FIPS mode if the key length is less than 112 bits.
To avoid this the option --pwd-session (-z) is added.
Here the session handle ESYS_TR_PASSWORD will be used.
For example, now the EK can be used to create a salted session:

tpm2_createek --pwd-session -Q --key-algorithm rsa --ek-context ek.ctx
tpm2_startauthsession -Q  --session salted_session.ctx --hmac-session --tpmkey-context ek.ctx
tpm2_sessionconfig -Q  salted_session.ctx --enable-decrypt
tpm2_createprimary -c prim.ctx -P session:salted_session.ctx
