The branch stable/14 has been updated by olce: URL: https://cgit.FreeBSD.org/src/commit/?id=1fa29df2cd37e74daa95c1150ec284b269db2e1f commit 1fa29df2cd37e74daa95c1150ec284b269db2e1f Author: Olivier Certner <olce@FreeBSD.org> AuthorDate: 2025-10-13 15:13:09 +0000 Commit: Olivier Certner <olce@FreeBSD.org> CommitDate: 2025-12-19 09:16:45 +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().
