[Impact]
On an 18.04 LTS system with a TPM, the TPM will fail intermittently on cold boots. The problem seems to be that the TPM gets into a state where the partial self-test doesn't return TPM_RC_SUCCESS (meaning all tests have run to completion), but instead returns TPM_RC_TESTING (meaning some tests are still running in the background). A reboot can sometimes restore TPM functionality.
This bug was originally reported on a Dell XPS 13, but has also recently been reported on a Dell Edge Gateway 3000.
The bug has been confirmed to be fixed in the current development release (19.04/Cosmic).
[Test Case]
Cold boot a Dell XPS 13 or Dell Edge Gateway 3000 running 18.04 LTS Desktop or Server and grep for the following error log message:
"tpm tpm0: A TPM error (2314) occurred continue selftest"
Any attempts at using the TPM via tpm2-tss libraries or tpm2-tools should produce errors.
As this bug is due to a race condition, ideally this test case would be run multiple times (20+ cold boots).
Once the patch is installed the following error message may still be present in the syslog, however attempts to use the TPM should work:
"tpm tpm0: A TPM error (2314) occurred attempting the self test"
[Regression Potential]
The chance of regression is low, as this patch was written by a well respected kernel developer with deep TPM experience. The patch is also being cherry-picked from the upstream stable and LTS kernels, and as mentioned, has already landed in Disco.
[Original Description]
After updating a Dell XPS 13 to 18.04 LTS, the TPM started to intermittently fail on cold boot. The following log messages could be observed in syslog:
[ 0.801334] tpm_tis MSFT0101:00: 2.0 TPM (device-id 0xFE, rev-id 4)
[ 0.812132] tpm tpm0: A TPM error (2314) occurred continue selftest
