https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211580 --- Comment #6 from Miroslav Lachman <000.fbsd@quip.cz> --- (In reply to Joe Barbish from comment #5) I don't think so. Attackers can use security.jail.jailed to show the truth. Leaking SW / HW info from the host to jail by dmesg should be avoided (with configurable sysctl) We are running all jailers with security.bsd.unprivileged_read_msgbuf=3D0 f= or this reason. --=20 You are receiving this mail because: You are the assignee for the bug.=
