Hi,
There is a null pointer dereference bug in the latest version of tboot-1.9.5.
The g_sinit of global variable is used in the function (tpm_detect()),but the
g_sinit is a null pointer at this time.
The detail of this prosess can be described as follows:
tpm_detect()
return g_tpm->init(g_tp

Hi,
There is no module images name when the latest tboot is used in Centos 7.2.
In Centos 7.2, it seems that grub2 does not pass boot image name to tboot.
When loading module images in Centos 7.2, the tboot shows "TBOOT: checking if
module is an SINIT for this platform..." in tboot log.
But in Ce
Hi,
There is an expression and output format problem.
Firstly,number of algorithms should be %d instead of %08X,it will be more
readable.
Secondly,log expression is not accurate.Tpm2.0 supports three algorithms,as
follows:
TBOOT: TPM: supported bank count = 3
TBOOT: TPM: bank alg = 0004
TBOO
= 000b
TBOOT: TPM: bank alg = 0012
TBOOT: TPM: supported alg count = 0002
TBOOT: 0004
TBOOT: 000B

Hi,
There is a logical error in function(bool evtlog_append(uint8_t pcr,
hash_list_t *hl, uint32_t type)).
In function evtlog_append,here always returns true whether it's TPM1.2 or
TPM2.0.

Hi,
There is a bug in hash_module function.
My machine is tpm2.0. As I have no machine of tpm1.2, I don't know whether it
has the same issue for the machine of tpm1.2.
When I set extpol=agile in the command line of tboot, module 1 can't be
measured.
Below is the related section of the TBOOT outp
