tpm2_nvpcr_initialize() already retries the initializing write when tpm2_extend_nvpcr_nv_index() reports that PCR values changed under its feet, which the comment there attributes to IMA measurements performed by the kernel. The policy session that write needs is opened in the same loop, and a PCR extended while that policy is submitted makes tpm2_policy_pcr() return -EUCLEAN, which was propagated as a hard failure instead. That is the same transient condition observed one step earlier, so let the loop absorb it too. Signed-off-by: Alberto Planas <aplanas@suse.com>
