selftest: tpm2: Add Client.del() to close /dev/tpm* handle

2022-10-04T21:25:56Z

The following output can bee seen when the test is executed: test_flush_context (tpm2_tests.SpaceTest) ... \ /usr/lib64/python3.6/unittest/case.py:605: ResourceWarning: \ unclosed file <_io.FileIO name='/dev/tpmrm0' mode='rb+' closefd=True> An instance of Client does not implicitly close /dev/tpm* handle, once it gets destroyed. Close the file handle in the class destructor Client.__del__().

selftests: tpm2: Determine available PCR bank

2022-03-08T08:33:17Z

Determine an available PCR bank to be used by a test case by querying the capability TPM2_GET_CAP. The TPM2 returns TPML_PCR_SELECTIONS that contains an array of TPMS_PCR_SELECTIONs indicating available PCR banks and the bitmasks that show which PCRs are enabled in each bank. Collect the data in a dictionary. From the dictionary determine the PCR bank that has the PCRs enabled that the test needs. This avoids test failures with TPM2's that either to not have a SHA-1 bank or whose SHA-1 bank is disabled.

tpm: selftest: add test covering async mode

2019-12-17T10:20:12Z

Add a test that sends a tpm cmd in an async mode. Currently there is a gap in test coverage with regards to this functionality. Signed-off-by: Tadeusz Struk Reviewed-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen

selftests/tpm2: Extend tests to cover partial reads

2019-04-08T22:58:55Z

Three new tests added: 1. Send get random cmd, read header in 1st read, read the rest in second read - expect success 2. Send get random cmd, read only part of the response, send another get random command, read the response - expect success 3. Send get random cmd followed by another get random cmd, without reading the first response - expect the second cmd to fail with -EBUSY Signed-off-by: Tadeusz Struk Reviewed-by: Jarkko Sakkinen Tested-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen Signed-off-by: James Morris
