Hi Other fixes are ready for the pull request but for this patch peer check might be useful.
I'm anyway sending the pull request with the five pull patches over here even if I don't get 'Tested-by:': https://github.com/jsakkine/linux-tpmdd/commits/fixes I've tested this patch with fTPM and dTPM and it does not have any side-effects to TPM 1.2. /Jarkko On Thu, Nov 05, 2015 at 12:20:23PM +0200, Jarkko Sakkinen wrote: > The 'migratable' flag was not added to the key payload.
