Currently FAPI provisioning tries to create the EK and SRK with the NULL auth value for the hierarchies. Now first the corresponding flag in TPM2_CAP_TPM_PROPERTIES with the property TPM2_PT_PERMANENT is checked. If an auth value is used for the hierarchy the auth value callback will be called. The "retry" code in the BAD_AUTH case is removed. Signed-off-by: Juergen Repp <juergen_repp@web.de>

Question: When you set an authValue and then you set the authValue back to NULL, does the authSet capability turn back to "false" ? |
