TPM microconf at Linux Plumbers Conference?

TPM microconf at Linux Plumbers Conference?

[Matthew Garrett]

Hi,

I'm looking into running a TPM microconference at the Linux Plubmers 
Conference in Santa Fe the first week of November. Right now we have a 
bunch of individual pieces of TPM-related technology, but little overall 
coherence - almost nobody ships working TPM-enabled bootloaders, we have 
no known-good PCR values available, distributions are unclear on what 
the appropriate TPM 2.0 userlands to ship are, we don't even have a spec 
for how PCRs should be used under Linux.

If this seems like it'd be useful, please add your name to 
http://wiki.linuxplumbersconf.org/2016:tpms along with any additional 
topics you'd like to discuss - and if you'd like to lead a short 
discussion session, drop me an email with a description.

Thanks!

Thanks for the proposal and pursuing this effort.
Not sure whether I can join, sine I should be back in Germany by that time.
Is a valid plumbers registration necessary?

Yes, you'd need to be registered - there's usually some number available 
for people leading discussion topics at microconferences, but I don't 
know for sure that that'd be possible.

FWIW, I will be attending plumbers as well, if there is no
conflict with the RDMA track I will try to attend the TPM sessions.

RDMA is a KS workshop, so it will be on Tuesday.  The Plumbers schedule
isn't out yet, but the plan is for Tuesday to be KS only, so the TPM MC
should be on Wed-Fri.

Did you consider submitting this as an Linux Security Summit (LSS)
discussion topic?

Yes, I've submitted something for that, but it would probably also be 
helpful to have discussion in a space with more general distribution 
developers.

There are two types of LSS talks - refereed or a discussion topic.  I'm
suggesting submitting the latter.   I'm not sure what you mean by more
general distribution developers.  Most of the distros have someone
attending LSS.

People involved in bootloader work, desktop integration and so on.

I'd be interested to join. If I get budget for this from my employer,
I'll be definitely here.

PS. One related topic worth of discussing would be event log handover
from boot loader to the OS. We need to find some defacto approach for
it shared by different boot loaders as TCG hasn't standardized anything
similar to TCPA for TPM2.

Is there a reference for "TCPA"?

TCPA just means Trusted Computing Platform Alliance.  I'm not sure if
this is what you're looking for but it's the TCPA architecture spec:

I stated things bit incorrectly in my original response.

The ACPI table called TCPA is a kind of counter part for TPM2 ACPI table
with TPM 1.x chips. The key problem with TPM2 table is that it does not
have a memory reference for the event log.

The problem to discuss is how could boot loaders handover such data to the
OS.

One topic I would like to suggest for the discussion is "Standardization 
of Device Tree Bindings for TPM".

Currently, TCG Specs also do not have information on Device Tree based 
mechanisms either for TPM 1.2 or TPM 2.0.

This has been accepted by Plumbers now, so the way you submit topics
for discussion is via the website:
