You updated the kernel version to 5.11 -- this version has its own SGX driver (built-in). This effectively disables the "default" DCAP SGX driver installed by Microsoft Azure under /usr/src/linux-headers-`uname -r`/arch/x86/
.
So you should delete your Graphene that you built previously, and rebuild it again following the same instructions. But you should specify make ISGX_DRIVER_PATH="" SGX=1
in step 3 now (this tells Graphene to use the built-in SGX driver).
Hi dimakuv, I have tried to run using this one "make ISGX_DRIVER_PATH="" SGX=1" in step 3 but I still have the same error, also I use ubuntu 20.04 gen2, or should I try to use ubuntu 18 and use the default kernel?
for the update, I have followed the same as the guide including ubuntu 18 and using the default the kernel. When I run "graphene-sgx helloworld", it return this error: Using insecure argv source. Graphene will continue application execution, but this configuration must not be used in productio n! Hello world!
So you got it running on Ubuntu 18.04. Congrats!
What happens on 20.04 I am not sure. Please try again from scratch, and don't forget to use make ISGX_DRIVER_PATH="" SGX=1
.
Yes, it works in ubuntu 18.04 kernel 5.4. Thank you for your help dimakuv, so for this error "error: Using insecure argv source" I don't need to worry right?
You don't need to worry about this error. This is perfectly normal (well, insecure but functional -- that's because we wrote a very simple HelloWorld example and didn't care much about its security).
ok thanks for your help, appreciate it
Hi, I have tried to deploy graphene in an Azure confidential computing machine. I follow this guide https://graphene.readthedocs.io/en/latest/cloud-deployment.html also, I have checked using is_sgx_available and the result is
SGX supported by CPU: true SGX1 (ECREATE, EENTER, ...): true SGX2 (EAUG, EACCEPT, EMODPR, ...): false Flexible Launch Control (IA32_SGXPUBKEYHASH{0..3} MSRs): true SGX extensions for virtualizers (EINCVIRTCHILD, EDECVIRTCHILD, ESETCONTEXT): false Extensions for concurrent memory management (ETRACKC, ELDBC, ELDUC, ERDINFO): false CET enclave attributes support (See Table 37-5 in the SDM): false Key separation and sharing (KSS) support (CONFIGID, CONFIGSVN, ISVEXTPRODID, ISVFAMILYID report fields): false Max enclave size (32-bit): 0x80000000 Max enclave size (64-bit): 0x1000000000 EPC size: 0x1c00000 SGX driver loaded: true AESMD installed: false SGX PSW/libsgx installed: false
when I try to run graphene-sgx helloworld
it shows an error
error: Cannot map enclave pages 1 error: Loading enclave binary failed: -13 error: load_enclave() failed with error -13
do you know how to solve this? also, I have upgraded the kernel version to 5.11 generic
