Generating a Software Bill of Materials (SBOM) with Open Source Standards and Tooling

The Linux Foundation - Tue, 03/16/2021 - 21:00

Every month there seems to be a new software vulnerability showing up on social media, which causes open source program offices and security teams to start querying their inventories to see how FOSS components they use may impact their organizations. 

Frequently this information is not available in a consistent format within an organization for automatic querying and may result in a significant amount of email and manual effort. By exchanging software metadata in a standardized software bill of materials (SBOM) format between organizations, automation within an organization becomes simpler, accelerating the discovery process and uncovering risk so that mitigations can be considered quickly. 

In the last year, we’ve also seen standards like OpenChain (ISO/IEC 5320:2020) gain adoption in the supply chain. Customers have started asking for a bill of materials from their suppliers as part of negotiation and contract discussions to conform to the standard. OpenChain has a focus on ensuring that there is sufficient information for license compliance, and as a result, expects metadata for the distributed components as well. A software bill of materials can be used to support the systematic review and approval of each component’s license terms to clarify the obligations and restrictions as it applies to the distribution of the supplied software and reduces risk. 

Kate Stewart, VP, Dependable Embedded Systems, The Linux Foundation, will host a complimentary mentorship webinar entitled Generating Software Bill Of Materials on Thursday, March 25 at 7:30 am PST. This session will work through the minimum elements included in a software bill of materials and detail the reasoning behind why those elements are included. To register, please click here

There are many ways this software metadata can be shared. The common SBOM document format options (SPDX, SWID, and CycloneDX) will be reviewed so that the participants can better understand what is available for those just starting. 

This mentorship session will work through some simple examples and then guide where to find the next level of details and further references. 

At the end of this session, participants will be on a secure footing and a path towards the automated generation of SBOMs as part of their build and release processes in the future.

Arch Linux Developers Discuss Idea Of Providing An x86-64-v3 Port

Phoronix - Tue, 03/16/2021 - 20:30
While recently Arch Linux developers and stakeholders were discussing the possibility of raising the x86-64 base requirements for this Linux distribution to the "x86-64-v2" micro-architecture feature level that roughly correlates to Intel Nehalem and newer, now the discussion has shifted to keeping the same x86-64 base level while potentially offering a "x86-64-v3" port for those with newer Intel/AMD CPUs...

How to write 'Hello World' in WebAssembly

opensource.com - Tue, 03/16/2021 - 15:01

WebAssembly is a bytecode format that virtually every browser can compile to its host system's machine code. Alongside JavaScript and WebGL, WebAssembly fulfills the demand for porting applications for platform-independent use in the web browser. As a compilation target for C++ and Rust, WebAssembly enables web browsers to execute code at near-native speed.

When you talk about a WebAssembly, application, you must distinguish between three states:
