System recently switched to hardened profile from desktop, an rsync-based backup script now fails. This is possibly an upstream known bug: https://github.com/WayneD/rsync/issues/511 Reproducible: Always Steps to Reproduce: 1. issue the following command: rsync -avx --delete --filter 'dir-merge /.exclude_from_backup' --filter 'dir-merge /.include_in_backup' --exclude-from /root/excluded_from_backup --include-from /root/included_in_backup /etc/ /mnt/backup/etc/ Actual Results: sending incremental file list *** buffer overflow detected ***: terminated rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(231) [sender=3.2.7] rsync: [receiver] write error: Broken pipe (32) rsync error: error in socket IO (code 10) at io.c(848) [receiver=3.2.7] Expected Results: Before switching to hardened profile the script copied the data without problems Portage 3.0.55 (python 3.11.6-final-0, default/linux/amd64/17.1/hardened, gcc-13, glibc-2.38-r7, 6.6.1-gentoo x86_64)
