Libre. Open.

This page provides a concise overview of the majority of my Libre Software contributions. Here, a "contribution" is defined as a code or documentation patch sent to the upstream project, accepted and merged into their main repository. I am deliberately not including projects where I serve in a management role (such as founding and continued contributions to Adélie Linux, gcompat, and PyIRC). These are covered in the Projects section of my CV.

Linux Kernel
Contributed a change to drivers/gpu/drm/amd fixing an out-of-bounds write.
musl libc
Multiple contributions, focused primarily on stability and POSIX correctness.
Rust
Corrected the definition of ioctl on musl/powerpc64 in the libc crate.
Mozilla
Worked with the gfx team on portability and byte ordering in primitive operations, including a direct commit fixing a logic error in swizzling. Also worked on implementing the OpenPower ABI in XPCOM and reading pointers on big-endian systems.
ffmpeg
Fixed compilation of HEVC/H.265 AltiVec routines.
Gentoo
Proxy-maintained net-irc/inspircd and pushed some KDE fixes through. Lots of bugfixes to crossdev and related mechanisms. Authored a dormant GLEP, GLEP 70, which dealt with formalising the "meta-distribution" aspect.
KDE
Added Tellico to KDE Homebrew, fixed multiple test and build system failures. Ported KFileMetaData's tests to Python 3. Fixed KPhotoAlbum build error on musl and Mac OS.
Git
Fixed a build system issue in the subtree module.
libmowgli
Multiple contributions, including thread safety, Windows portability, and various compilation issues.
Valgrind
Implemented support for OpenPower ABI on big-endian Power.
ifupdown-ng
Implemented the ifctrstat subcommand, showing per-interface statistics, in an operating system-agnostic manner.
Charybdis IRCd
Multiple contributions, including porting modules to AV2, fixing m_error and the build system, and fixing a remote DoS in MONITOR.
iperf
Fixed auth test logic on 32-bit systems with 64-bit timestamps.
gettext-tiny
Multiple contributions, including C++ compatibility for headers, parameter/argument parsing fixes, and documentation.
abuild
Many varied contributions. Support for bsdtar, split OpenRC for alternate service manager support, wrote principle documentation of the APKBUILD recipe format, and more.
APK Tools
Fixed a logic error in detecting orphaned packages, debugged a stack allocated variable used after return, and more - mostly around cross-builds.
pkgconf
Responsibly disclosed, and fixed, what became known as CVE-2018-1000221 (CVSS v3.0 9.8/10).
Node.js
Fixed a nullptr dereference in the Environment module.
pam_url
Worked with Seth Vidal on modernising and overhauling the codebase for use by the Fedora Infraastructure team.
whisper.cpp
Provided code review for OpenPower support in this C++ port of OpenAI's speech recognition model.
efivar
Implemented byteswap routines for musl libc compatibility.
cracklib
Corrected gettext usage for musl and NixOS systems.
BTRFS
Fixed a documentation build issue.
libucontext
Fixed a logic error where the link pointer was written to the wrong part of the stack on 32-bit x86 systems.
Repology
Many contributions for metadata fixes, version corrections, and other improvements.
ConsoleKit2
Implemented the elogind interface ListSeats for cross-environment compatibility.
Stacker
Corrected the ABI used on musl libc PowerPC systems.
