I audit Dynamic Resource Allocation for arithmetic and lifecycle bugs. It began with an int64 overflow in quota accounting, which I reported in kueue#12896, fixed across four merged pull requests, then found and fixed in Volcano.
The audit has since reached the Kubernetes core structured allocator, where five fixes have merged with release notes into the v1.37 milestone: a counter-cache collision between DRA drivers (#140434 fixed in #140435), a reserved-state leak on the reject/backtrack path (#140436 fixed in #140431), a shared counter double-counted for a persisted device (#140433 fixed in #140437), a divide-by-zero on a validRange.step that slips past its Sign() guard through Value() truncation (#140472 fixed in #140666), and a roundUpRange overflow that admitted a device it could not satisfy (#140441 fixed in #140442). The same class of bug reached Intel's QAT DRA driver, a device leak on the claim-unprepare path (#73 fixed in #74), and CNCF's container-device-interface, a slice-bounds panic on a single-character vendor name.
Still under review: more core pull requests on the same consumable-capacity arithmetic, a nil dereference in KubeVirt's host-device builder, and quota-accounting problems in KAI-Scheduler.
I want to help more people cross from using cloud native software to contributing to it: newcomer sessions in Mandarin and Taiwanese, and bilingual contribution walkthroughs drawn from real review threads. I completed LFC102 (Inclusive Open Source Community Orientation) in July 2026.
