Intel(R) Software Guard Extensions for Linux* OS

linux-sgx

Introduction

Intel(R) Software Guard Extensions (Intel(R) SGX) is an Intel technology for application developers seeking to protect select code and data from disclosure or modification.

The Linux* Intel(R) SGX software stack is comprised of the Intel(R) SGX driver, the Intel(R) SGX SDK, and the Intel(R) SGX Platform Software (PSW). The Intel(R) SGX SDK and Intel(R) SGX PSW are hosted in the linux-sgx project.

The SGXDataCenterAttestationPrimitives project maintains an out-of-tree driver for the Linux* Intel(R) SGX software stack, which will be used until the driver upstreaming process is complete. It is used on the platforms with Flexible Launch Control and Intel(R) AES New Instructions support and could support both Elliptic Curve Digital Signature algorithm (ECDSA) based attestation and Enhanced Privacy Identification (EPID) based attestation.
The linux-sgx-driver project hosts the other out-of-tree driver for the Linux* Intel(R) SGX software stack, which will be used until the driver upstreaming process is complete. It is used to support Enhanced Privacy Identification (EPID) based attestation on the platforms without Flexible Launch Control.

The repository provides a reference implementation of a Launch Enclave for 'Flexible Launch Control' under psw/ae/ref_le. The reference LE implementation can be used as a basis for enforcing different launch control policy by the platform developer or owner. To build and try it by yourself, please refer to the ref_le.md for details.

Note: To build Intel(R) SGX SDK, GNU binutils version is required to be 2.26 or above. For Red Hat Enterprise Linux 7.4, you may need to update GNU binutils version using below command:

 $ sudo yum update binutils

Note: To build Intel(R) SGX SDK, gcc version is required to be 7.3 or above and glibc version is required to be 2.27 or above. For Ubuntu 16.04, Red Hat Enterprise Linux 7.4, CentOS 7.5, Fedora 27, SUSE Linux Enterprise Server 12, you may need to update gcc and glibc version.

Use the following command to install additional required tools and latest Intel(R) SGX SDK Installer to build the Intel(R) SGX PSW:
1. To install the additional required tools:
  - On Ubuntu 16.04 and Ubuntu 18.04:
```
  $ sudo apt-get install libssl-dev libcurl4-openssl-dev protobuf-compiler libprotobuf-dev debhelper cmake reprepro
```
  - On Red Hat Enterprise Linux 7.4, Red Hat Enterprise Linux 8.0, CentOS 7.5 and Fedora 27:
```
  $ sudo yum install openssl-devel libcurl-devel protobuf-devel cmake rpm-build createrepo yum-utils
```
  - On SUSE Linux Enterprise Server 12:
```
  $ sudo zypper install libopenssl-devel libcurl-devel protobuf-devel cmake rpm-build createrepo
```
  Note: To build Intel(R) SGX PSW, GNU binutils version is required to be 2.26 or above. For Red Hat Enterprise Linux 7.4, you may need to update GNU binutils version using below command:
```
 $ sudo yum update binutils
```
2. To install latest Intel(R) SGX SDK Installer Ensure that you have downloaded latest Intel(R) SGX SDK Installer from the Intel(R) SGX SDK and followed the Installation Guide in the same page to install latest Intel(R) SGX SDK Installer.
Use the script download_prebuilt.sh inside source code package to download prebuilt binaries to prebuilt folder
You may need set an https proxy for the wget tool used by the script (such as export https_proxy=http://test-proxy:test-port)

  $ ./download_prebuilt.sh

Copy the mitigation tools from external/toolset to /usr/local/bin and make sure they have execute permission:
```
  $ sudo cp external/toolset/{as,ld,ld.gold,objdump} /usr/local/bin
  $ which as ld ld.gold objdump
```

Build the Intel(R) SGX SDK and Intel(R) SGX SDK Installer

To build Intel(R) SGX SDK with default configuration, enter the following command:

  $ make sdk

You can find the three flavors of tools and libraries generated in the build directory.

This repository supports to build the Intel(R) SGX SDK with below three combinations:
- USE_OPT_LIBS=0 --- build SDK using SGXSSL and open sourced String/Math
- USE_OPT_LIBS=1 --- build SDK using optimized IPP crypto and open sourced String/Math The default build uses USE_OPT_LIBS=1, if you directly type $ make sdk as above. You can switch to the other build combination instead by entering the following command:

  $ make sdk USE_OPT_LIBS=0

Note: Building the Intel(R) SGX PSW with open sourced SGXSSL/string/math libraries is not supported.

To build Intel(R) SGX SDK with debug information, enter the following command:

  $ make sdk DEBUG=1

To clean the files generated by previous make sdk command, enter the following command:

  $ make clean

To build the Intel(R) SGX SDK installer, enter the following command:

  $ make sdk_install_pkg

You can find the generated Intel(R) SGX SDK installer sgx_linux_x64_sdk_${version}.bin located under linux/installer/bin/, where ${version} refers to the version number.

Note: The above command builds the Intel(R) SGX SDK with default configuration firstly and then generates the target SDK Installer. To build the Intel(R) SGX SDK Installer with debug information kept in the tools and libraries, enter the following command:

  $ make sdk_install_pkg DEBUG=1

Build the Intel(R) SGX PSW and Intel(R) SGX PSW Installer

To build Intel(R) SGX PSW with default configuration, enter the following command:

  $ make psw

You can find the tools and libraries generated in the build/linux directory. Note: You can also go to the psw folder and use the make command to build the Intel(R) SGX PSW component only.

To build Intel(R) SGX PSW with debug information, enter the following command:

  $ make psw DEBUG=1

To clean the files generated by previous make psw command, enter the following command:

  $ make clean

The build above uses prebuilt Intel(R) Architecture Enclaves(LE/PvE/QE/PCE) - the files psw/ae/data/prebuilt/libsgx_*.signed.so, which have been signed by Intel in advance. To build those enclaves by yourself (without a signature), first you need to install latest Intel(R) SGX SDK from the Intel(R) SGX SDK and then build PSW with the default configuration. After that, you can build each Architecture Enclave by using the make command from the corresponding folder:

  $ cd psw/ae/le
  $ make

To build the Intel(R) SGX PSW installer, enter the following command:
- On Ubuntu 16.04 and Ubuntu 18.04:
```
$ make deb_psw_pkg
```
You can find the generated Intel(R) SGX PSW installers located under linux/installer/deb/libsgx-urts, linux/installer/deb/libsgx-enclave-common, linux/installer/deb/libsgx-uae-service, linux/installer/deb/libsgx-epid, linux/installer/deb/libsgx-launch, linux/installer/deb/libsgx-quote-ex and linux/installer/deb/sgx-aesm-service respectively.

Note: On Ubuntu 18.04, besides the Intel(R) SGX PSW installer, the above command generates another debug symbol package named package-name-dbgsym_${version}-${revision}_amd64.ddeb for debug purpose. On Ubuntu 16.04, if you want to keep debug symbols in the Intel(R) SGX PSW installer, before building the Intel(R) SGX PSW, you need to export an environment variable to ensure the debug symbols not stripped:
```
$ export DEB_BUILD_OPTIONS="nostrip"
```
Note: The above command builds the Intel(R) SGX PSW with default configuration firstly and then generates the target PSW Installer. To build the Intel(R) SGX PSW Installer without optimization and with full debug information kept in the tools and libraries, enter the following command:
```
$ make deb_psw_pkg DEBUG=1
```
- On Red Hat Enterprise Linux 7.4, Red Hat Enterprise Linux 8.0, CentOS 7.5, Fedora 27 and SUSE Linux Enterprise Server 12:
```
$ make rpm_psw_pkg
```
You can find the generated Intel(R) SGX PSW installers located under linux/installer/rpm/libsgx-urts, linux/installer/rpm/libsgx-enclave-common, linux/installer/rpm/libsgx-uae-service, linux/installer/rpm/libsgx-epid, linux/installer/rpm/libsgx-launch, linux/installer/rpm/libsgx-quote-ex and linux/installer/rpm/sgx-aesm-service respectively.

Note: The above command builds the Intel(R) SGX PSW with default configuration firstly and then generates the target PSW Installer. To build the Intel(R) SGX PSW Installer with debug information kept in the tools and libraries, enter the following command:
```
$ make rpm_psw_pkg DEBUG=1
```
- To build local Debian package repository, enter the following command:
```
$ make deb_local_repo
```
You can find the local package repository located under linux/installer/deb/sgx_debian_local_repo.

Note: The above command builds the local package repository. If you want to use it, you need to add it to the system repository configuration. The local package repository is not signed, you need to trust it for the purpose of development.
- To add the local Debian package repository to the system repository configuration, append the following line to /etc/apt/sources.list. You need to replace PATH_TO_LOCAL_REPO with the proper path on your system:
- On Ubuntu 16.04:
```
deb [trusted=yes arch=amd64] file:/PATH_TO_LOCAL_REPO xenial main
```
- On Ubuntu 18.04:
```
deb [trusted=yes arch=amd64] file:/PATH_TO_LOCAL_REPO bionic main
```
After that, you need to update the apt:
- On Ubuntu 16.04 and Ubuntu 18.04:
```
$ sudo apt update
```
- To build local RPM package repository, enter the following command:
```
$ make rpm_local_repo
```
You can find the local package repository located under linux/installer/rpm/sgx_rpm_local_repo.

Note: The above command builds the local package repository. If you want to use it, you need to add it to the system repository configuration. Since the local package repository is not signed with GPG, you should ignore the gpgcheck when installing the packages.
- To add the local RPM package repository to the system repository configuration, you can use the following command. You need to replace PATH_TO_LOCAL_REPO with the proper path on your system:
- On Red Hat Enterprise Linux 7.4, Red Hat Enterprise Linux 8.0, CentOS 7.5, Fedora 27:
```
$ sudo yum-config-manager --add-repo file://PATH_TO_LOCAL_REPO
```
- On SUSE Linux Enterprise Server 12, you need to replace LOCAL_REPO_ALIAS with proper alias name for the local repo:
```
$ sudo zypper addrepo PATH_TO_LOCAL_REPO LOCAL_REPO_ALIAS
```
- To ignore the gpgcheck when you install the package, enter the following command:
- On Red Hat Enterprise Linux 7.4, Red Hat Enterprise Linux 8.0, CentOS 7.5, Fedora 27:
```
$ sudo yum --nogpgcheck install <package>
```
- On SUSE Linux Enterprise Server 12:
```
$ sudo zypper --no-gpg-checks install <package>
```

Test the Intel(R) SGX SDK Package with the Code Samples

Compile and run each code sample in Simulation mode to make sure the package works well:

  $ cd SampleCode/LocalAttestation
  $ make SGX_MODE=SIM
  $ cd bin
  $ ./app

Use similar commands for other sample codes.

Compile and Run the Code Samples in the Hardware Mode

If you use an Intel SGX hardware enabled machine, you can run the code samples in Hardware mode. Ensure that you install Intel(R) SGX driver and Intel(R) SGX PSW installer on the machine.
See the earlier topic, Build and Install the Intel(R) SGX Driver, for information on how to install the Intel(R) SGX driver.
See the later topic, Install Intel(R) SGX PSW, for information on how to install the PSW package.

Compile and run each code sample in Hardware mode, Debug build, as follows:

  $ cd SampleCode/LocalAttestation
  $ make
  $ cd bin
  $ ./app

Use similar commands for other code samples.

Note: GNU binutils version is required to be 2.26 or above to build SGX Enclaves starting from Linux 2.8 release. For Red Hat Enterprise Linux 7.4, you may need to update GNU binutils version using below command:
$ sudo yum update binutils

Install the Intel(R) SGX PSW

Prerequisites

Ensure that you have one of the following operating systems:
- Ubuntu* 16.04 LTS Desktop 64bits
- Ubuntu* 16.04 LTS Server 64bits
- Ubuntu* 18.04 LTS Desktop 64bits
- Ubuntu* 18.04 LTS Server 64bits
- Red Hat Enterprise Linux Server release 7.4 64bits
- Red Hat Enterprise Linux Server release 8.0 64bits
- CentOS 7.5 64bits
- Fedora 27 Server 64bits
- SUSE Linux Enterprise Server 12 64bits
Ensure that you have a system with the following required hardware:
- 6th Generation Intel(R) Core(TM) Processor or newer
Configure the system with the Intel SGX hardware enabled option and install Intel(R) SGX driver in advance.
See the earlier topic, Build and Install the Intel(R) SGX Driver, for information on how to install the Intel(R) SGX driver.

Install the library using the following command:

On Ubuntu 16.04 and Ubuntu 18.04:

  $ sudo apt-get install libssl-dev libcurl4-openssl-dev libprotobuf-dev

On Red Hat Enterprise Linux 7.4, Red Hat Enterprise Linux 8.0, CentOS 7.5 and Fedora 27:

  $ sudo yum install openssl-devel libcurl-devel protobuf-devel

On SUSE Linux Enterprise Server 12:

  $ sudo zypper install libopenssl-devel libcurl-devel protobuf-devel

Install the Intel(R) SGX PSW

The SGX PSW provides 3 services: launch, EPID-based attestation, and algorithm agnostic attestation. Starting with the 2.8 release, the SGX PSW is split into smaller packages and the user can choose which features and services to install. There are 2 methods to install the required packages: Using individual packages or using the local repo generated by the build system. Using the local repo is recommended since the system will resolve the dependencies automatically. Currently, we support .deb and .rpm based repos.

Using the local repo(recommended)

	Ubuntu 16.04 and Ubuntu 18.04	Red Hat Enterprise Linux 7.4, Red Hat Enterprise Linux 8.0, CentOS 7.5, Fedora 27	SUSE Linux Enterprise Server 12
launch service	apt-get install libsgx-launch libsgx-urts	yum install libsgx-launch libsgx-urts	zypper install libsgx-launch libsgx-urts
EPID-based attestation service	apt-get install libsgx-epid libsgx-urts	yum install libsgx-epid libsgx-urts	zypper install libsgx-epid libsgx-urts
algorithm agnostic attestation service	apt-get install libsgx-quote-ex libsgx-urts	yum install libsgx-quote-ex libsgx-urts	zypper install libsgx-quote-ex libsgx-urts

Optionally, you can install *-dbgsym or *-debuginfo packages to get the debug symbols, and install *-dev or *-devel packages to get the header files for development.

NOTE: To debug with sgx-gdb on Ubuntu 16.04, you need to ensure the Intel(R) SGX PSW is built under the condition that the environment variable DEB_BUILD_OPTIONS="nostrip" is set.

Using the individual packages

Please refer Intel_SGX_Installation_Guide_Linux for detail.

Upgrade from a legacy installation

Before release 2.8, SGX PSW is installed as a single package named as libsgx-enclave-common. Starting with the 2.8 release, SGX PSW is split into smaller packages. libsgx-enclave-common is one of them. As a result, a simple upgrade will end up with a subset of the SGX PSW being installed on the system. You need to install additional packages to enable the required feature. At the same time, you will encounter some error message when you try to upgrade to release 2.8 from an old installation. You can use 2 methods to address it.

Uninstall the old installation first, then install new packages.
Add -o Dpkg::Options::="--force-overwrite" option to overwrite existing files and use “dist-upgrade” instead of "upgrade" to install new packages when upgrading. In short, you should use this command:

apt-get dist-upgrade -o Dpkg::Options::="--force-overwrite"

Configure the installation

Some packages are configured with recommended dependency on other packages that are not required for certain usage. For instance, the background daemon is not required for container usage. It will be installed by default, but you can drop it by using the additional option during the installation.

On Ubuntu 16.04 and Ubuntu 18.04:

  --no-install-recommends

NOTE On rpm based system, rpmbuild>=4.12 is required to enable similar features.

ECDSA attestation

To enable ECDSA attestation

Ensure that you have the following required hardware:
- 8th Generation Intel(R) Core(TM) Processor or newer with Flexible Launch Control support*
- Intel(R) Atom(TM) Processor with Flexible Launch Control support*
To use ECDSA attestation, you must install Intel(R) Software Guard Extensions Driver for Data Center Attestation Primitives (Intel(R) SGX DCAP). Please follow the Intel(R) SGX DCAP Installation Guide for Linux* OS to install the Intel(R) SGX DCAP driver.

NOTE: If you had already installed Intel(R) SGX driver without ECDSA attestation, please uninstall the driver firstly and then install the Intel(R) SGX DCAP driver. Otherwise the newly installed Intel(R) SGX DCAP driver will be unworkable.

Install Quote Provider Library(QPL). You can use your own customized QPL or use default QPL provided by Intel(libsgx-dcap-default-qpl)
Install PCK Caching Service. For how to install and configure PCK Caching Service, please refer to SGXDataCenterAttestationPrimitives
Ensure the PCK Caching Service is setup correctly by local administrator or data center administrator. Also make sure that the configure file of quote provider library (/etc/sgx_default_qcnl.conf) is consistent with the real environment, for example: PCS_URL=https://your_pcs_server:8081/sgx/certification/v1/

Start or Stop aesmd Service

The Intel(R) SGX PSW installer installs an aesmd service in your machine, which is running in a special linux account aesmd.
To stop the service: $ sudo service aesmd stop
To start the service: $ sudo service aesmd start
To restart the service: $ sudo service aesmd restart

Configure the Proxy for aesmd Service

The aesmd service uses the HTTP protocol to initialize some services.
If a proxy is required for the HTTP protocol, you may need to manually set up the proxy for the aesmd service.
You should manually edit the file /etc/aesmd.conf (refer to the comments in the file) to set the proxy for the aesmd service.
After you configure the proxy, you need to restart the service to enable the proxy.
