Description Peter Robinson 2020-09-15 11:28:21 UTC 
The TPM2 gets put into the tss user/group via udev rules in /usr/lib/udev/rules.d/60-tpm-udev.rules but the tss user/group isn't created unless the trousers package is installed.

This causes userspace issues with access to the TPM2, like if clevis is unlocking user partitions post root switch (AKA not in the initrd where everything is run as root).

In most cases now the trousers package  isn't installed because TPM2 has been the standard for a long time and TPM1 units are generally considered insecure so the tpm2-tss package should check if the user/group exists and if not create them per packaging policy.

This affects userspace TPM2 access, it doesn't affect unlocking an encrypted root filesystem as this is done as the root user in the initrd, but it affects clevis unlocking non root filesystems on a different LUKS partition such as /home or /opt as well as other TPM2 access from userspace.
Comment 1 Fedora Blocker Bugs Application 2020-09-15 11:44:18 UTC 
Proposed as a Freeze Exception for 33-beta by Fedora user pbrobinson using the blocker tracking app because:

 Causing issues on Fedora IoT and other TPM2 related bits. Not sure if it's considered a blocker or a FE as it works on clevis if it's a single LUKS partition with LVM for root and other filesystems, but if there's any LUKS that would get unlocked post switch root it's causing issues.
Comment 2 Peter Robinson 2020-09-15 11:45:34 UTC 
The tpm2-tss package is currently failing to build due to some change in doxygen, but the fix has been pushed.
