Subject: [tboot-devel] PATCH: Fix linux command line after 429:664e69

Don't skip first argument in Linux kernel command line

Since 429:664e696da669, tboot doesn't skip the first argument of a given 
command line any more. Consequently, it shouldn't be skipped either when passed 
to the kernel in expand_linux_image().

I only have TPM1.2 laptops with TXT, however I have a couple of TPM 2.0 laptops
without TXT. https://github.com/01org/tpm2.0-tools.git has tools that work
with my TPM, such as tpm2_listpcrs and commands like tpm2_nvread/nvwrite.
Might be worth looking to see if there's anything from there that you can
use.

[tboot-devel] Question about TXT + TPM 2.0

2016-02-23 Thread Wilck, Martin 
There's one point about TXT + TPM 2.0 I couldn't figure out. I can see
that tboot itself supports TPM 2.0. I can also see lcptools_v2 to create
policies for it. But tools for writing policy to TPM 2.0 NVM seem to be
missing. This seems understandable as there is no "standard" TSS 2.0
user space yet - but what's the plan for users, how are they supposed to
commit LCP2.0 policy to the TPM NVM?

Thanks,
Martin
