[tpm2] tpm2-tss question

Hello, I found one problem about the TPM Dictionary Attack Lock mechanism. I executed the following command sequence to check the functionality of DictionaryAttackLockReset. (1) DictionaryAttackLockReset (right authValue) , rval=0 (2) DictionaryAttackParameters  (wrong authValue), rval=98e (3) DictionaryAttackParameters  (right authValue), rval=921 <StartAuthSession(Policy)> <Compute Policy> (4) DictionaryAttackLockReset  (lockoutPolicy), rval=0 (5) DictionaryAttackLockReset  (right authValue), rval=921 From the following document "TCG Library Specification 1.38 Part1 19.8.5 Authorization Failures Involving lockoutAuth" lockoutAuth. The TPM will exit this state when TPM2_DictionaryAttackLockReset() is used with a successful lockoutPolicy or after the TPM is powered for a configurable time period (lockoutRecovery). I assume that in (1) and (5), the result will be the same. However, different return codes is produced I would like to know why they are different.. -----  Yasuhiro Hosoda NTT Electronics Corporation （NEL)
