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

2022-10-26T10:35:29+00:00

[ Upstream commit 2d869f0b458547386fbcd8cf3004b271b7347b7f ]

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: tpm: Use /bin/sh instead of /bin/bash

2020-06-29T20:19:38+00:00

It's better to use /bin/sh instead of /bin/bash in order to run the tests
in the BusyBox shell.

selftests: tpm: Use 'test -e' instead of 'test -f'

'test -f' is suitable only for *regular* files. Use 'test -e' instead.

Revert "tpm: selftest: cleanup after unseal with wrong auth/policy test"

2020-06-29T20:18:15+00:00

The reverted commit illegitly uses tpm2-tools. External dependencies are
absolutely forbidden from these tests. There is also the problem that
clearing is not necessarily wanted behavior if the test/target computer is
not used only solely for testing.

Kernel selftests: Add check if TPM devices are supported

2020-05-22T19:19:57+00:00

TPM2 tests set uses /dev/tpm0 and /dev/tpmrm0 without check if they
are available. In case, when these devices are not available test
fails, but expected behaviour is skipped test.

This reverts commit b32694cd0724d4ceca2c62cc7c3d3a8d1ffa11fc.

The original comment was neither reviewed nor tested. Thus, this the
*only* possible action to take.

tpm2 tests set fails if there is no /dev/tpm0 and /dev/tpmrm0
supported. Check if these files exist before run and mark test as
skipped in case of absence.

tpm: selftest: cleanup after unseal with wrong auth/policy test

2019-12-17T10:20:15+00:00

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.

tpm: selftest: add test covering async mode

2019-12-17T10:20:12+00:00

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.
