From experiment, th= is parameter seems to work, but it's always displayed as 0. The children.curr= ent parameter is supposed to be a read-only sysctl displaying the current numbe= r of children. However it, too, always displays 0. The jls command can correct= ly display these parameters for child jails, but I don't see any way to get th= em from within a jail. Steps to reproduce: [somers@fbsd12 ~]$ sudo jail -c name=3Dfoo host.hostname=3Dfoo children.max= =3D99 persist [somers@fbsd12 ~]$ jls -h jid name children.max children.cur=20=20=20=20 jid name children.max children.cur 7 foo 99 0 [somers@fbsd12 ~]$ sudo jexec foo /bin/sh # sysctl security.jail.param.children security.jail.param.children.max: 0 security.jail.param.children.cur: 0 # jail -c name=3Dbar host.hostname=3Dbar persist # sysctl security.jail.param.children security.jail.param.children.max: 0 security.jail.param.children.cur: 0 # exit [somers@fbsd12 ~]$ jls -h jid name children.max children.cur jid name children.max children.cur 7 foo 99 1 8 foo.bar 0 0 Tested on 12.0-BETA4 and 12.0-CURRENT as of r340301. --=20 You are receiving this mail because: You are the assignee for the bug.=
