Yocto Project

Projects that follow the best practices below can voluntarily self-certify and show that they've achieved an Open Source Security Foundation (OpenSSF) best practices badge.

If this is your project, please show your badge status on your project page! The badge status looks like this: Badge level for project 765 is silver Here is how to embed it:

These are the Gold level criteria. You can also view the Passing or Silver level criteria.

        

 Basics 5/5

  • Identification

    The Yocto Project is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded products regardless of the hardware architecture.

  • Prerequisites


    The project MUST achieve a silver level badge. [achieve_silver]

  • Project oversight


    The project MUST have a "bus factor" of 2 or more. (URL required) [bus_factor]

    We average over 25 different contributors per week: http://git.yoctoproject.org/cgit.cgi/poky/stats/?period=w&ofs=-1



    The project MUST have at least two unassociated significant contributors. (URL required) [contributors_unassociated]

    We have multiple contributors from multiple companies: http://git.yoctoproject.org/cgit.cgi/poky/stats/?period=w&ofs=-1


  • Other


    The project MUST include a license statement in each source file. This MAY be done by including the following inside a comment near the beginning of each file: SPDX-License-Identifier: [SPDX license expression for project]. [license_per_file]

    We have SPDX-License-Identifier lines in our source code


  • Public version-controlled source repository


    The project's source repository MUST use a common distributed version control software (e.g., git or mercurial). [repo_distributed]

    The project MUST clearly identify small tasks that can be performed by new or casual contributors. (URL required) [small_tasks]

    The project MUST require two-factor authentication (2FA) for developers for changing a central repository or accessing sensitive data (such as private vulnerability reports). This 2FA mechanism MAY use mechanisms without cryptographic mechanisms such as SMS, though that is not recommended. [require_2FA]


    The project's two-factor authentication (2FA) SHOULD use cryptographic mechanisms to prevent impersonation. Short Message Service (SMS) based 2FA, by itself, does NOT meet this criterion, since it is not encrypted. [secure_2FA]

    Warning: Requires lengthier justification.


  • Coding standards


    The project MUST document its code review requirements, including how code review is conducted, what must be checked, and what is required to be acceptable. (URL required) [code_review_standards]

    We have documentation about patch submission referred to in our README files in each repository and these point at documents like http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded



    The project MUST have at least 50% of all proposed modifications reviewed before release by a person other than the author, to determine if it is a worthwhile modification and free of known issues which would argue against its inclusion [two_person_review]

    All patches are posted on the mailing list and peer reviewed before testing and merging,


  • Working build system


    The project MUST have a reproducible build. If no building occurs (e.g., scripting languages where the source code is used directly instead of being compiled), select "not applicable" (N/A). (URL required) [build_reproducible]

    We require our builds to reproducible, test this and publish results: https://www.yoctoproject.org/reproducible-build-results/


  • Automated test suite


    A test suite MUST be invocable in a standard way for that language. (URL required) [test_invocation]

    We have many forms of automated testing which conform to standards where possible (e.g. python unittest). See our testing manual: http://docs.yoctoproject.org/test-manual/index.html



    The project MUST implement continuous integration, where new or changed code is frequently integrated into a central code repository and automated tests are run on the result. (URL required) [test_continuous_integration]

    We have extensive automated CI testing: https://autobuilder.yoctoproject.org/typhoon/#/console



    The project MUST have FLOSS automated test suite(s) that provide at least 90% statement coverage if there is at least one FLOSS tool that can measure this criterion in the selected language. [test_statement_coverage90]

    We use our own metadata and languages so this isn't applicable



    The project MUST have FLOSS automated test suite(s) that provide at least 80% branch coverage if there is at least one FLOSS tool that can measure this criterion in the selected language. [test_branch_coverage80]

    We use our own metadata and languages so this isn't applicable


  • Use basic good cryptographic practices

    Note that some software does not need to use cryptographic mechanisms. If your project produces software that (1) includes, activates, or enables encryption functionality, and (2) might be released from the United States (US) to outside the US or to a non-US-citizen, you may be legally required to take a few extra steps. Typically this just involves sending an email. For more information, see the encryption section of Understanding Open Source Technology & US Export Controls.

    The software produced by the project MUST support secure protocols for all of its network communications, such as SSHv2 or later, TLS1.2 or later (HTTPS), IPsec, SFTP, and SNMPv3. Insecure protocols such as FTP, HTTP, telnet, SSLv3 or earlier, and SSHv1 MUST be disabled by default, and only enabled if the user specifically configures it. If the software produced by the project does not support network communications, select "not applicable" (N/A). [crypto_used_network]

    We prefer secure versions of networking components



    The software produced by the project MUST, if it supports or uses TLS, support at least TLS version 1.2. Note that the predecessor of TLS was called SSL. If the software does not use TLS, select "not applicable" (N/A). [crypto_tls12]

    We support TLS 1.2


  • Secured delivery against man-in-the-middle (MITM) attacks


    The project website, repository (if accessible via the web), and download site (if separate) MUST include key hardening headers with nonpermissive values. (URL required) [hardened_site]

    X-Content-Type-Options was not set to "nosniff". // X-Content-Type-Options was not set to "nosniff".


  • Other security issues


    The project MUST have performed a security review within the last 5 years. This review MUST consider the security requirements and security boundary. [security_review]

    The project TSC has discussed and revised the project's security actions within the last 5 years and made many improvements such as the automated and frequency CVE scans which can be seen on the yocto-security mailing list,



    Hardening mechanisms MUST be used in the software produced by the project so that software defects are less likely to result in security vulnerabilities. (URL required) [hardening]

    The project is a configurable build system and users can chose to include many different levels of hardening. By default we include compiler options, this can range through to selinux and other software from the meta-security layer http://git.yoctoproject.org/cgit.cgi/meta-security


  • Dynamic code analysis


    The project MUST apply at least one dynamic analysis tool to any proposed major production release of the software produced by the project before its release. [dynamic_analysis]

    The project uses many forms of testing appropriate to a build system.



    The project SHOULD include many run-time assertions in the software it produces and check those assertions during dynamic analysis. [dynamic_analysis_enable_assertions]

    The codebase does sanity check its state where it needs to and would warn/error as appropriate if conditions warranted it.
