Security fix breaks --link-dest via rsync daemon

[fufu65]

I usually perform backups via rsync daemon or to local disks, maintaining a history with hard links.
With the latest security backports in version 3.2.7 (3.2.7-0ubuntu0.22.04.6 on Ubuntu 22.04.5 LTS, 3.2.7-1ubuntu1.4 on Ubuntu 24.04.4 LTS), the --link-dest option does not work in daemon mode:

rsync -arAX --delete \
	--files-from="/path/to/files_to_add" -exclude-from="/path/to/exclude_patterns" \
	--link-dest="../01" "/" "rsync://USER@HOST:PORT/DEST/00/"

On the deamon host the "01" dir contains the last backup, while the "00" dir is initially empty.
No errors are reported; all files are simply transferred again... and after 2 backup cycles my backup disks are full :-(
In local mode this doesn't happen, and rsync still works correctly:

rsync -arAX --delete \
	--files-from="/path/to/files_to_add" -exclude-from="/path/to/exclude_patterns" \
	--link-dest="../01" "/" "/path_to_backup_dir/00/"

Downgrading the packages even just on the daemon host (3.2.7-0ubuntu0.22.04.4 on Ubuntu 22.04.5 LTS, 3.2.7-1ubuntu1.2 on Ubuntu 24.04.4 LTS) restores the correct behavior.
I have not had the opportunity to check other versions or systems.
