I can confirm the scenario described in comment #5 is what is causing the issue. There are two ways to correctly fix it: 1- ask for the right directory that matches the forced command, or 2- use the new --old-args option that was backported to the security update, that should bypass the new security checks.

Automated syncs that connect to a 16.04 ESM server are now failing with: receiving file list ... ERROR: rejecting unrequested file-list name: [redacted] rsync error: protocol incompatibility (code 2) at flist.c(916) [Receiver=3.1.3] Reverting to the previous release (3.1.3-8ubuntu0.4) on the client side solves the problem. This has been seen on multiple servers running 20.04 on amd64, I'll update this bug with details if we find it on other series too. The 16.04 ESM server being connected to is using the rsync package version 3.1.1-3ubuntu1.3+esm2, so no recent upgrades on that end.
