Google and the Linux Foundation announced that they are prioritizing funds to underwrite two full-time maintainers for Linux kernel security development, Gustavo Silva and Nathan Chancellor.
Silva and Chancellor’s exclusive focus will be to maintain and improve kernel security and associated initiatives in order to ensure the world’s most pervasive open source software project is sustainable for decades to come.
Chancellor’s work will be focused on triaging and fixing all bugs found with Clang/LLVM compilers while working on establishing continuous integration systems to support this work ongoing. Once those aims are well-established, he plans to begin adding features and polish to the kernel using these compiler technologies.
Chancellor has been working on the Linux kernel for four and a half years. Two years ago, Chancellor started contributing to mainline Linux under the ClangBuiltLinux project, which is a collaborative effort to get the Linux kernel building with Clang and LLVM compiler tools.
Gustavo Silva’s full-time Linux security work is currently dedicated to eliminating several classes of buffer overflows by transforming all instances of zero-length and one-element arrays into flexible-array members, which is the preferred and least error-prone mechanism to declare such variable-length types.
Additionally, he is actively focusing on fixing bugs before they hit the mainline, while also proactively developing defense mechanisms that cut off whole classes of vulnerabilities. Silva sent his first kernel patch in 2010 and today is an active member of the Kernel Self Protection Project (KSPP).
He is consistently one of the top five most active kernel developers since 2017 with more than 2,000 commits in mainline. Silva’s work has impacted 27 different stable trees, going all the way down to Linux v3.16.
