Jimmy,
THANKS!
Your suggestions got me going in the right direction and I seem to have things
booting correctly.
I had to add a couple of things to get things working.
1) Had to add tpm_takeownership -z to the process.
2) Added the TPM error index setup (0x20000002) to the process.
I've added the script that I used below for reference. It might help someone
else out.
Thanks to all for the help!
Jay S.
###
### Provide passwork on command line.
###
if [ -z $1 ]; then
echo ""
echo "ERROR: Forgot password!"
echo ""
exit 1
fi
mypw=$1
###
### Pause / wait for key
###
function pause(){
read -p "==>> Hit Key!"
}
###
### Set verbose setting to show executed commands.
###
set -v
###
### Create MLE element
###
lcp_mlehash -c "logging=serial,vga,memory" /boot/tboot.gz > mle_hash
lcp_crtpolelt --create --type mle --ctrl 0x00 --minver 17 --out mle.elt mle_hash
pause
###
### Combine elements
###
lcp_crtpollist --create --out list_unsig.lst mle.elt
###
### Sign list - signing and software on same platform
###
openssl genrsa -out privkey.pem 2048
openssl rsa -pubout -in privkey.pem -out pubkey.pem
cp list_unsig.lst list_sig.lst
lcp_crtpollist --sign --pub pubkey.pem --priv privkey.pem --out list_sig.lst
###
### Create policy and policy data files
###
lcp_crtpol2 --create --type list --pol list.pol --data list.data list_sig.lst
pause
###
### Take ownership of TPM, tpm_takeownership will prompt you for passwords
###
tcsd
tpm_takeownership -z
###
### Define tboot error TPM NV index
###
tpmnv_defindex -i 0x20000002 -s 8 -pv 0 -rl 0x07 -wl 0x07 -p $mypw
###
### Define owner in NV space.
###
tpmnv_defindex -i owner -p $mypw
###
### Write LCP and launch policy to TPM
###
lcp_writepol -i owner -f list.pol -p $mypw
pause
###
### Copy list.data to /boot.
### Modify /boot/grub/grub.cfg to use list.data:
### module /list.data /list.data
###
