Go: Platform Parsing and Shared-State Bugs
Today's fixes both trace back to code that was shared across multiple consumers without accounting for their differences — one in networking on DragonFly BSD, one in structured logging with multiple handlers.

Good day, and welcome to Go, your daily developer briefing for September 13th, 2026.
The common thread today: shared code that assumed all its callers were alike, when they weren't.
First, PR 81504 from sigttou fixes interface parsing on DragonFly BSD. The underlying code, interface classic, was shared across Darwin, DragonFly, and NetBSD, but it used the message layout specific to FreeBSD and Darwin for all three. DragonFly actually places its interface index and address flags in different…
Second, a commit from cuishuang, 9834516, fixes a related class of bug in log slash slog's Multi Handler. When you call "with attrs" on a handler, ownership of that attributes slice passes to the receiver. Multi Handler was handing the exact same slice to every handler it wrapped — so if one handler modified its…
Both changes point to the same lesson: when one chunk of code is reused by several consumers, differences in expectations — whether it's memory layout on DragonFly or slice ownership in a handler chain — need explicit handling, not silent assumption.
What's next: expect DragonFly BSD networking to be more reliable in upcoming builds, and if you're chaining multiple slog handlers, this…
