selftests: tpm2: test_smoke: use POSIX-conformant expression operator

2025-04-08T20:56:13Z

Use POSIX-conformant expression operator symbol '='. The use of the non POSIX-conformant symbol '==' would work in bash, but not in sh where the unexpected operator error would result in test_smoke.sh being skipped. Instead of changing the shebang to use bash, which may not be available on all systems, use the POSIX-conformant expression symbol '=' to test for equality. Without this patch: =================== # make -j8 TARGETS=tpm2 kselftest # selftests: tpm2: test_smoke.sh # ./test_smoke.sh: 9: [: 2: unexpected operator ok 1 selftests: tpm2: test_smoke.sh # SKIP With this patch: ================ # make -j8 TARGETS=tpm2 kselftest # selftests: tpm2: test_smoke.sh # Ran 9 tests in 9.236s ok 1 selftests: tpm2: test_smoke.sh Link: https://lore.kernel.org/r/37ztyakgrrtgvec344mg7mspchwjpxxtsprtjidso3pwkmm4f4@awsa5mzgqmtb Signed-off-by: Ahmed Salem Reviewed-by: Jarkko Sakkinen Signed-off-by: Shuah Khan

selftests: tpm2: test_smoke: Run only when TPM2 is avaialable.

2024-09-17T15:56:37Z

Since Linux 5.6 tpm_version_major sysfs file is avaialble which gives the TPM version. Using this file the test can be skipped on systems with TPM 1.2. Signed-off-by: Michal Suchanek Reviewed-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen

selftests/tpm2: Split async tests call to separate shell script runner

2022-11-30T00:28:31Z

When the async test case was introduced, despite being a completely independent test case, the command to run it was added to the same shell script as the smoke test case. Since a shell script implicitly returns the error code from the last run command, this effectively caused the script to only return as error code the result from the async test case, hiding the smoke test result (which could then only be seen from the python unittest logs). Move the async test case call to its own shell script runner to avoid the aforementioned issue. This also makes the output clearer to read, since each kselftest KTAP result now matches with one python unittest report. While at it, also make it so the async test case is skipped if /dev/tpmrm0 doesn't exist, since commit 8335adb8f9d3 ("selftests: tpm: add async space test with noneexisting handle") added a test that relies on it.

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

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

2020-06-29T20:18:15Z

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.
