src/bin/uuidgen, branch main FreeBSD source tree uuidgen: generate UUIDs in bounded batches to respect kernel limit 2026-03-07T07:51:16+00:00 NVSRahul nvsrahul@hotmail.com 2026-01-13T05:52:06+00:00 3570b19d74ed94dcc7fac2dcbf42b378bc72362e The uuidgen(2) system call enforces a hard upper limit of 2048 UUIDs per invocation. uuidgen(1) previously attempted to generate arbitrary counts in a single call and allocated memory accordingly, leading to EINVAL errors, unnecessary memory usage, and potential overflow risks. Generate UUIDs in fixed-size batches, streaming output incrementally while preserving existing semantics. Mirror the kernel limit explicitly since it is not exposed via a public interface.
