From 4ae70c3ea498e06676040ee99254d261e29ae82e Mon Sep 17 00:00:00 2001 From: Olivier Certner Date: Mon, 13 Oct 2025 17:13:09 +0200 Subject: 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().
