Penglai is a RISC-V TEE system, which is designed to be secure, high-performant, and scalable. This repo maintains OpenSBI version of Penglai Enclave based on PMP.
How to use?
Simply replace the OpenSBI used in your system with opensbi-0.9/1.0/1.2 in the top directory in the repo.
You can use our SDK and enclave-driver to build your trusted applications, or even write your own SDKs.
- Status: experimental: it's still experimental version now, please refer our TVM version for more features.
- Hardware requirement:for openEuler version
$\le$ 20.03, riscv qemu version:$\geq$ 5.2.0 is fine;for openEuler version$\ge$ 22, qemu version:$\geq$ 8.0 is suggested. - Supported software system: This repo contains resources to run openEuler with Penglai TEE.
- Real devices: Penglai for Nuclei devices is maintained in Nuclei Linux SDK.
You can turn to BBL-version by switching to the master branch.
You can refer our Penglai-TVM for more advanced features, including inter-enclave communication, secure storage, shadow fork, and others.
Penglai uses Docker for building and uses submodules to track different componets. Therefore, the only requirement to build and run penglai-demo is:
- Docker: for building/running Penglai
- Git: for downloading the code
- Qemu for RISC-V (RV64): suggested version >= 8.0. You can download the qemu here and follow the instructions to build and install qemu.
For openEuler version
There is no need to compile uboot.
# Fetch the uboot submodule
git submodule update --init --recursive
For openEuler version
Follow the instructions in openeuler riscv gitee to compile uboot for OE-23.X.
# Fetch the uboot submodule
git submodule update --init --recursive
docker run -v $(pwd):/home/penglai/penglai-enclave -w /home/penglai/penglai-enclave --network=host --rm -it fly0307/penglai-enclave:v0.5 bash
cd ./u-boot
make qemu-riscv64_smode_defconfig
make ARCH=riscv CROSS_COMPILE=riscv64-unknown-linux-gnu- -j$(nproc)
For openEuler version
Follow the instructions in openeuler riscv gitee to compile openEuler kernel.
For example, download the OKL-5.10 in current directory, and compile with penglai's docker image:
docker run -v $(pwd):/home/penglai/penglai-enclave -w /home/penglai/penglai-enclave --rm -it ddnirvana/penglai-enclave:v0.5 bash
# In the docker image
./scripts/build_euler_kernel.sh
For openEuler version
For oe versions greater than 23, you can access the source code after Run openEuler with Penglai Supports and don't need to compile the image like in the previous step for version
If you want to use opensbi 0.9 or 1.0, you need to use the previous version of the penglai-enclave-driver, the corresponding commit is bb5021cd9f76d033d6e174b2b96bbc4503766385. And you can use the latest penglai-enclave-driver to support opensbi-1.2.
For openEuler version
When compiling opensbi-0.9/1.0, you can use the toolchain CROSS_COMPILE=/home/penglai/toolchain-720/bin/riscv64-unkown-linux-gnu-. For opensbi-1.2, you can use CROSS_COMPILE=riscv64-unknown-linux-gnu-.
cp openeuler-kernel/arch/riscv/boot/Image .
docker run -v $(pwd):/home/penglai/penglai-enclave -w /home/penglai/penglai-enclave --rm -it fly0307/penglai-enclave:v0.5 bash
# In the docker image
cd /home/penglai/penglai-enclave/opensbi-0.9
mkdir -p build-oe/qemu-virt
CROSS_COMPILE=/home/penglai/toolchain-720/bin/riscv64-unkown-linux-gnu- make O=build-oe/qemu-virt PLATFORM=generic FW_PAYLOAD=y FW_PAYLOAD_PATH=/home/penglai/penglai-enclave/Image
Note: the /home/penglai/penglai-enclave/Image is the image compiled openEuler Kernel Image.
A simple way:
For opensbi-0.9 and oe-2203(oe
./docker_cmd.sh opensbi-0.9
For openEuler version
docker run -v $(pwd):/home/penglai/penglai-enclave -w /home/penglai/penglai-enclave --rm -it fly0307/penglai-enclave:v0.5 bash
cd /home/penglai/penglai-enclave/opensbi-1.2
rm -rf build-oe/qemu-virt
mkdir -p build-oe/qemu-virt
CROSS_COMPILE=riscv64-unknown-linux-gnu- make O=build-oe/qemu-virt PLATFORM=generic FW_PAYLOAD=y FW_PAYLOAD_PATH=/home/penglai/penglai-enclave/u-boot/u-boot.bin -j$(nproc)
A simpler way:
For opensbi-1.2 and oe-2303(oe
./docker_cmd.sh opensbi-1.2
For others
./docker_cmd.sh docker
#In the docker image，build opensbi 1.2 for OE20.03
#./scripts/build_opensbi.sh -v [opensbi version] -k [openEuler version]
./scripts/build_opensbi.sh -v 1.2 -k 2003
Note: if you use the simpler way, please copy your latest kernel Image file to the root dir of the repo.
For openEuler version
When openeuler version is less than 23,following the commands to build enclave driver:
./docker_cmd.sh docker
# In the docker image
./scripts/build_enclave_driver.sh
It will generate penglai.ko in the penglai-enclave-driver dir.
For openEuler version
When openEuler version is >= 23, you need to start openEuler in qemu as the next step Run openEuler with Penglai Supports finished before compiling penglai-driver.
When penglai.ko is completed,following the commnads to build user-level sdk and demos:
#In host, fetch the sdk submodule
git submodule update --init --recursive
./docker_cmd.sh docker
# In the docker image
cd sdk
PENGLAI_SDK=$(pwd) make -j8
You should download the disk image of openEuler (i.e., openEuler-preview.riscv64.qcow2) and raname image file to openEuler-xxxx-qemu-riscv64.qcow2.
You can download OE 2303 from openEuler-23.03-V1-riscv64(i.e., openEuler-23.03-V1-base-qemu-preview.qcow2)or download openEuler 20.03 from here.
wget https://mirror.iscas.ac.cn/openeuler-sig-riscv/openEuler-RISC-V/preview/openEuler-23.03-V1-riscv64/QEMU/openEuler-23.03-V1-base-qemu-preview.qcow2.zst
unzstd openEuler-23.03-V1-base-qemu-preview.qcow2.zst
mv openEuler-23.03-V1-base-qemu-preview.qcow2 openEuler-2303-qemu-riscv64.qcow2
For openEuler version
Run VM in QEMU：
# For openEuler version is 20.03
qemu-system-riscv64 -nographic -machine virt \
-smp 4 -m 2G \
-kernel ./opensbi-0.9/build-oe/qemu-virt/platform/generic/firmware/fw_payload.elf \
-drive file=openEuler-preview.riscv64.qcow2,format=qcow2,id=hd0 \
-object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-device,rng=rng0 \
-device virtio-blk-device,drive=hd0 \
-device virtio-net-device,netdev=usernet \
-netdev user,id=usernet,hostfwd=tcp::12055-:22 \
-append 'root=/dev/vda1 rw console=ttyS0 systemd.default_timeout_start_sec=600 selinux=0 highres=off mem=4096M earlycon' \
-bios none
- The test qemu version is 5.2.0 or 8.0.0.
- The fw_payload.elf is the opensbi file.
- The openEuler-preview.riscv64.qcow2 is the disk image for openEuler (You can download from https://repo.openeuler.org/openEuler-preview/RISC-V/).
- To login, username is "root", passwd is "openEuler12#$"
Note: a script, run_openeuler.sh is provided to execute the above command easily
./run_openeuler.sh -k [openEuler version] -o [opensbi version]
#when openEuler version less than 23,eg 2003
./run_openeuler.sh -k 2003 -o 1.2
If everything is fine, you will enter a Linux terminal booted by Qemu with Penglai-installed.
For openEuler version
Run VM in QEMU：
qemu-system-riscv64 -nographic -machine virt \
-smp 4 -m 2G \
-bios ./opensbi-1.2/build-oe/qemu-virt/platform/generic/firmware/fw_payload.bin \
-drive file=openEuler-2303-qemu-riscv64.qcow2,format=qcow2,id=hd0 \
-object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-device,rng=rng0 \
-device virtio-blk-device,drive=hd0 \
-device virtio-net-device,netdev=usernet \
-netdev user,id=usernet,hostfwd=tcp::12055-:22 \
-device qemu-xhci -usb -device usb-kbd -device usb-tablet
Once started, you should execut the following command to obtain the kernel module compilation environment. Execute the following commands and the kernel source code will be downloaded locally, the path is /usr/lib/modules/6.1.19-2.oe2303.riscv64(For openEuler 2303).
#in VM
cd ~/
dnf install -y kernel-devel kernel-source
a simple way:
./run_openeuler.sh -k [openEuler version] -o [opensbi version]
#when openEuler version is greater than or equal 23,eg 2303
./run_openeuler.sh -k 2303 -o 1.2
For openEuler version
Copy files to openEuler Qemu
You can copy any files to the VM using scp.
For example, to run the following demo, you should:
#For version 23, there is no need to copy penglai.ko
scp -P 12055 penglai-enclave-driver/penglai.ko root@localhost:~/
scp -P 12055 sdk/demo/host/host root@localhost:~/
scp -P 12055 sdk/demo/prime/prime root@localhost:~/
The passwd is "openEuler12#$"
For openEuler version
After starting the VM, you need to get the source code in the qemu VM and execute compile kernel moudle with penglai-driver for openEuler version
Copy penglai-enclave-driver to the root/ directory of the oe VM:
#in host
scp -P 12055 -r penglai-enclave-driver root@localhost:~/
scp -P 12055 sdk/demo/host/host root@localhost:~/
scp -P 12055 sdk/demo/prime/prime root@localhost:~/
Go into the penglai-enclave-driver directory and modify the original kernel source path openeuler-kernel in the Makefile from ../openeuler-kernel/to /usr/lib/modules/$(shell uname -r)/build/.
Compile and install the kernel module:
cd ~/penglai-enclave-driver
#modify source path
sed -i 's|make -C ../openeuler-kernel/ ARCH=riscv M=$(PWD) modules|make -C /usr/lib/modules/$(shell uname -r)/build ARCH=riscv M=$(PWD) modules|' Makefile > /dev/null 2>&1
make -j$(nproc)
insmod penglai.ko
Insmod the enclave-driver
If you already installed in the previous step, you don't need to repeat it
cd ~/
insmod penglai.ko
And the, you can run a demo, e.g., a prime enclave, using
./host prime
Here, the host is an enclave invoker, which will start an enclave (name from input).
