Package: systemd Version: 241-5 Severity: normal Dear Maintainer,
the systemd-nspawn syscall filter is incomplete and does not whitelist the sync_file_range2 syscall. ARM has two sync_file_range syscalls, sync_file_range and sync_file_range2. The former is apparently not used, and glibc calls the latter whenever a userspace program calls sync_file_range. Hence every program using this syscall's glibc wrapper inside a systemd-nspawn container on ARM (and probably PPC) will fail. A similar report filed for Ubuntu bionic contains additional information and example code that will fail in the given situation: <https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1840640> The bug affects packages like borgbackup and postgres in those environments: <https://github.com/borgbackup/borg/issues/4710> <https://www.postgresql.org/message-id/flat/CA%2BhUKG%2BydOUT4zjxb6QmJWy8U9WbC-q%2BJWV7wLsEY9Df%3Dmw0Mw%40mail.gmail.com#ac8f14897647dc7eae3c7e7cbed36d93> A very straight-forward fix is present in <https://github.com/systemd/systemd/pull/13352>.
