Hi,
I used tpm-tools finding a problem that is cmd of tpm_nvinfo,when
using 'tpm_nvinfo --i index',information got about size is zero.I
don't know why.Can you give me some advice?
I don't know where this stems from but I just had tpm-tools-1.3.7-2 on
Fedora 17 installed and it showed the same with trouser-0.3.9-1. I
removed tpm-tools and compiled the ones from the git repository and they
worked fine showing correct PCR read and write selections and
permissions as well, which also seem to be wrong with the tools from the
1.3.7-2 package. So my recommendation would be to use the sources fro git.
The same I download source code of tpm-tools,whose version is
1.3.8.The trousers installed is Version: 0.3.7-2ubuntu1.1,but when I
make the tpm-tools meeting a error "tpm_tspi.c:706:2: error: implicit
declaration of function 'Trspi_UnloadBlob_NV_DATA_PUBLIC'
[-Werror=implicit-function-declaration]".
This version of trousers is probably too old since all the NVRAM stuff
went in after 0.3.7 -- probably the reason for the tpm-tools error I see
with FC17. You should get a more recent trousers, possibly also from
git, and use that one to compile the latest tss and latest tpm-tools.

Stefan
