ego run remote-attestation error #157

Future318 · 2022-07-29T09:36:56Z

I'v installed ego using release binary and run helloworld successfully. But I got error while running remote-attestation and attestation-tls exmaple.

Please help me to solve this problem.Thanks

Hi,
Is this a local machine or cloud?
Are you running your own PCCS? Can you show its output?

Future318 · 2022-08-08T07:29:25Z

Run the server on local machine.
PCCS show some outputs

And a different error occurred.

Is this error related to the config file.

etc/sgx_default_qcnl.conf has been modified

thomasten · 2022-08-08T09:15:10Z

Please try setting use_secure_cert to false in sgx_default_qcnl.conf.

Future318 · 2022-08-08T09:35:38Z

I modified the setting, but it didn't work.

The error message has changed.

This seems to be similar to #158 (comment). Maybe it can be fixed by updating the BIOS.

@Wyh19980916 it seems that sgx_default_qcnl.conf is using JSON format, so the format you're using does not match the syntax I guess. I have adapted the parameters to match the JSON syntax though it still does not work for me. Below is the output of the entire /etc/sgx_default_qcnl.conf file:

Future318 · 2022-08-09T08:27:22Z

@EErikas Thanks.But I think both formats do the same thing. I have modified the file as you said，but it still prompts the same error message.https://community.intel.com/t5/Intel-Software-Guard-Extensions/Error-No-cache-data-for-this-platform/m-p/1397969#M5380 propose a solution.If you solve the problem, please tell me. My server BIOS information is as follows

thomasten · 2022-08-14T17:34:56Z

@Wyh19980916 Please run https://github.com/edgelesssys/sgx-troubleshoot and copy and paste the full output. Maybe I can then identify what might be wrong.

Future318 · 2022-08-15T02:47:07Z

Firstly,I run the program and it output logs are as follow.

ERROR: get remote report: OE_SGX_QUOTE_LIBRARY_ERROR

It looks likes missing dynamic link file. But libsgx_dcap_ql.so.1 exists in /usr/lib/x86_64-linux-gnu. I use ln -s libsgx_dcap_ql.so.1 libsgx_dcap_ql.so to create link and run the program again.

  // If you use a PCCS service to get the quote verification collateral, you can specify which PCCS API version is to be used.
  // The legacy 3.0 API will return CRLs in HEX encoded DER format and the sgx_ql_qve_collateral_t.version will be set to 3.0, while
  // the new 3.1 API will return raw DER format and the sgx_ql_qve_collateral_t.version will be set to 3.1. The PCCS_API_VERSION 
  // setting is ignored if COLLATERAL_SERVICE is set to the Intel PCS. In this case, the PCCS_API_VERSION is forced to be 3.1 
  // internally.  Currently, only values of 3.0 and 3.1 are valid.  Note, if you set this to 3.1, the PCCS use to retrieve

According to sdibc-Super-Server aesm_service[293306]: [get_qpl_handle ../qe_logic.cpp:294] Cannot open Quote Provider Library libdcap_quoteprov.so.1 and libdcap_quoteprov.so .Is the problem caused by this library?

thomasten · 2022-08-15T08:02:11Z

The tool's output is truncated at the end. Can you post the rest, too?

As a side note:

sh -c lsmod | grep -i sgx
graphene_sgx           16384  0
isgx                   57344  0

You should uninstall these two drivers because they aren't required on an SGX-FLC machine with kernel >= 5.11. But it's probably unrelated to your problem.

Future318 · 2022-08-15T08:33:43Z

I waited for ten minutes,but the tool stopped printing after this error .

thomasten · 2022-08-15T08:36:13Z

Okay. Can you post the output of just ./sgx-troubleshoot without arguments then?

thomasten · 2022-08-15T09:09:12Z

According to the ouput, the bios_version is 1.1c. There seems to be an update to 1.2a: https://www.supermicro.com/en/support/resources/downloadcenter/firmware/MBD-X12DPi-N6
This might fix the problem.

Future318 · 2022-08-15T09:40:54Z

I have some questions.When I use EGO to compile the program, it can only use GOROOT, or can i use GOPATH like go. Maybe I might need to use go mod to manage dependency

thomasten · 2022-08-15T10:36:27Z

Since Go 1.16 you need to set GO111MODULE=off to use GOPATH. This should work with EGo, too.

Future318 · 2022-08-24T07:36:10Z

The BIOS has been updated to the latest version, but the issue remains the same.

thomasten · 2022-08-24T10:51:48Z

Do you use the Docker image that we provide as PCCS? I just updated it. It now prints more error messages. You can update it with

docker pull ghcr.io/edgelesssys/pccs

Then start a new container of it, run the remote attestation sample or the sgx-troubleshoot tool and look at the PCCS output.

Future318 · 2022-08-25T02:41:35Z

I have updated the docker image,and these are the output.
