selftests: tpm2: Fix ill defined assertions

2025-12-03T20:55:27+00:00

Remove parentheses around assert statements in Python. With parentheses, assert always evaluates to True, making the checks ineffective. Signed-off-by: Maurice Hieronymus Signed-off-by: Jarkko Sakkinen

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

2025-04-08T20:56:13+00:00

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.

selftests: tpm2: create a dedicated .gitignore

2025-04-08T20:56:13+00:00

The tpm2 selftests produce two logs: SpaceTest.log and AsyncTest.log. Only SpaceTest.log was listed in selftests/.gitignore, while AsyncTest.log remained untracked. This change creates a dedicated .gitignore in the tpm2/ directory to manage these entries, keeping tpm2-specific patterns isolated from parent .gitignore.

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

2022-11-30T00:28:31+00:00

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.
