The chrony files don't have any set*id bits set, but the chronyd process, like many other daemons, calls setuid()/setgid() in order to drop root privileges. The proc(5) man page lists that as a reason for not producing a coredump. I was wondering what security implications would setting suid_dumpable to 2 by default had and why it needs to be restricted to development. -- Miroslav Lichvar -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
