https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D262179 --- Comment #6 from firk@cantconnect.ru --- It should be noted, that there are another ways to escape jail via shared nullfs when it is done badly. I did not tried to fix them in any way, the p= atch is to fix jail-escaping only for properly configured nullfs: 1) both shared mounts have exactly same underlying base directory 2) underlying base directory for nullfs is placed on a separate filesystem, otherwise invisible to the jails. --=20 You are receiving this mail because: You are the assignee for the bug.=
