The branch releng/15.0 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=082e48e81bd10237e534c9ba88d270abb9351a36 commit 082e48e81bd10237e534c9ba88d270abb9351a36 Author: Olivier Certner <olce@FreeBSD.org> AuthorDate: 2025-10-13 15:13:09 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2025-10-16 18:48:17 +0000 sys/rpc: UNIX auth: Support XDR_FREE xdr_authunix_parms() does not allocate any auxiliary memory, so we can simply support XDR_FREE by just returning TRUE. Although there are currently no callers passing XDR_FREE, this makes us immune to such a change in a way that doesn't cost more but is more constructive than a mere KASSERT().
