How BIND 9 schedules callbacks — isc_job_run (same loop), isc_async_run (any thread → any loop), isc_work_enqueue (offload to a worker thread). Use when deciding where a callback should run, deferring a call to break lock re-entrancy or unwind the stack,…

Methodology for root-causing hard concurrency / memory-ordering bugs (intermittent races, use-after-free, RCU/lock-free publish-order defects, "impossible" stale reads) with LTTng flight-recorder (snapshot) tracing — when static analysis, printf, and a…

Measure and fix C struct layout in BIND 9 — pahole on the build's DWARF for sizes, padding holes, and cacheline boundaries, plus the house cacheline-padding idiom. Use when asked about struct size, padding, false sharing, or when adding/reordering members in…
