The approach looks fine to me. The only basic query I have is about the default: shouldn't it be with resource manager on rather than off? I can't really think of a use case that wants the RM off (even if you're running your own, having another doesn't hurt anything, and it's still required to share with in-kernel uses). > There's a test script for trying out TPM spaces in > > git://git.infradead.org/users/jjs/tpm2-scripts.git > > A simple smoke test can be run by > > sudo python -m unittest -v tpm2_smoke.SpaceTest I've also added an enabling patch to the tss https://build.opensuse.org/package/view_file/home:jejb1:Tumbleweed/tss2/0002-tssProperties-add-TPM_USE_RESOURCE_MANAGER.patch?expand=1 And with that, I've TPM 2 enabled both gnome-keyring and openssl: https://build.opensuse.org/package/show/home:jejb1:Tumbleweed/gnome-keyring https://build.opensuse.org/package/show/home:jejb1:Tumbleweed/openssl_tpm_engine I'm running them in production on my day to day laptop and so far everything's working nicely (better than 1.2, in fact, since tcsd periodically crashes necessitating a restart of everything). So you can definitely add my Tested-By. James
