Subject: [PATCH =v2 3/3] tpm: selftest: cleanup after unseal with wrong auth/policy test
Date: Thu, 12 Dec 2019 09:48:59 -0800	[thread overview]
Message-ID: <157617293957.8172.1404790695313599409.stgit@tstruk-mobl1> (raw)
In-Reply-To: <157617292787.8172.9586296287013438621.stgit@tstruk-mobl1>

Unseal with wrong auth or wrong policy test affects DA lockout
and eventually causes the tests to fail with:
"ProtocolError: TPM_RC_LOCKOUT: rc=0x00000921"
when the tests run multiple times.
Send tpm clear command after the test to reset the DA counters.
