Subject: tpm: Provide a TPM access library
Date: Tue, 21 Aug 2018 16:56:49 +0100
Message-ID: <153486700916.13066.12870860668352070081.stgit@warthog.procyon.org.uk> (raw)


Hi Denis, Jarkko, James,

I managed to recover the TPM library patchset that I was working on about four
years ago in the process of trying to write an asymmetric key subtype that
could use the TPM.

Here it is in it's original glory for reference.  I ended up leaving it
because Jarkko's tpm-2 stuff broke it and I had other things to work on.  If
it's deemed worthwhile, I can try to forward port it to current Linus/mastet.

Note that one or two of the preliminary patches may be upstream.

The patches can also be found here:

Thanks,
David
