Problem with ressourcemanager / abrmd : ERROR: Could not load tcti, got: "device" #1238

Closed ghost closed 5 years ago

ghost commented 5 years ago

Hello,

i am testing tpm stack on a dell xps with a tpm2 integrated. OS is ubuntu 18.04 LTS kernel version: 4.15.0-36-generic

I have compiled sources as described on the documentation, i can start either abrmd or ressourcemanager services using systemd,

the problem is that when i execute simple command with the ressource manager or abrmd started i get this error:

ERROR:tcti:src/tss2-tcti/tcti-device.c:319:Tss2_Tcti_Device_Init() Failed to open device file /dev/tpm0: Device or resource busy 
ERROR: tcti init allocation routine failed for library: "device" options: "(null)"
ERROR: Could not load tcti, got: "device"

without a abrmd or ressourcemanager commands line are working fine.

until i get this error when trying to load a key:


root@iRRo1:~/tpm2-src/tpm2-tools# tpm2_load -C context.primary -u key.pub -r key.priv -o key.ctx
ERROR: Tss2_Sys_Load(0x902) - tpm:warn(2.0): out of memory for object contexts

i saw in other thread that only 3 handle can be supported once and that ressourcemanager is suppossing dealing with that.

could you please tell me if i am missing something ?

any idea about the problem ?

Where is the shared library installed for the tabrmd tcti? Did you install from source? You may have to run sudo ldconfig to update the dynamic linker metadata cache.

kind regards.

yes, i have installed from sources,

but i can only see this shared libraries:
