I am using tboot.1.9.6 on CentOS 7.5 with TPM 1.2. Using the following to
create the policy:
lcp_mlehash -c "${GRUB_CMDLINE_TBOOT}" /boot/tboot.gz > mle_hash
lcp_crtpolelt --create --type mle --ctrl 0x00 --minver 17 --out mle.elt
mle_hash
cat `find /sys/devices -name pcrs` | grep -e PCR-0[01] > pcrs
lcp_crtpolelt --create --type pconf --out pconf.elt pcrs
lcp_crtpollist --create --out list_unsig.lst mle.elt pconf.elt
openssl genrsa -out privkey.pem 2048 &> /dev/null
openssl rsa -pubout -in privkey.pem -out pubkey.pem &> /dev/null
cp list_unsig.lst list_sig.lst
lcp_crtpollist --sign --pub pubkey.pem --priv privkey.pem --out list_sig.lst
but this always crashes with
*** Error in `lcp_crtpollist': double free or corruption (out):
0x0000000001d387f0 ***
Segmentation fault
Is this a known problem?
