Noticed this when doing sysctl -Na | grep jail... in particular the sysctl MIBs that have a trailing '.' are odd: security.jail.param.allow.mount.zfs security.jail.param.allow.mount.procfs security.jail.param.allow.mount.nullfs security.jail.param.allow.mount.devfs security.jail.param.allow.mount. security.jail.param.allow.socket_af security.jail.param.allow.quotas security.jail.param.allow.chflags security.jail.param.allow.raw_sockets security.jail.param.allow.sysvipc security.jail.param.allow.set_hostname security.jail.param.ip6.saddrsel security.jail.param.ip6.addr security.jail.param.ip6. security.jail.param.ip4.saddrsel security.jail.param.ip4.addr security.jail.param.ip4. security.jail.param.cpuset.id security.jail.param.host.hostid security.jail.param.host.hostuuid security.jail.param.host.domainname security.jail.param.host.hostname security.jail.param.host. security.jail.param.children.max security.jail.param.children.cur security.jail.param.dying security.jail.param.persist security.jail.param.devfs_ruleset security.jail.param.enforce_statfs security.jail.param.securelevel security.jail.param.path security.jail.param.name security.jail.param.parent security.jail.param.jid security.jail.param.linux. security.jail.param.linux.osname security.jail.param.linux.osrelease security.jail.param.linux.oss_version security.jail.devfs_ruleset security.jail.enforce_statfs security.jail.mount_zfs_allowed security.jail.mount_procfs_allowed security.jail.mount_nullfs_allowed security.jail.mount_devfs_allowed security.jail.mount_allowed security.jail.chflags_allowed security.jail.allow_raw_sockets security.jail.sysvipc_allowed security.jail.socket_unixiproute_only security.jail.set_hostname_allowed security.jail.jail_max_af_ips security.jail.jailed security.jail.list

The sysctl name that have a trailing '.' are normal: they are normal sysctl objects with a `struct sysctl_oid` in the MIB but their name `sysctl_oid.oid_name` is just "\0". I mentioned them at the BSDCan 2020 and in some quarterly status report to describe sysutils/sysctlinfo-kmod, sysutils/sysctlbyname-improved-kmod and devel/sysctlmibinfo2. We can use sysutils/nsysctl to know their properties: % nsysctl -OFIHtN -s ', ' security 2147482851, security, node, N, Undefined ... 2147482851.2147482945, security.jail, node, N, Undefined ... 2147482851.2147482945.2147482932, security.jail.param, node, N, Undefined 2147482851.2147482945.2147482932.2147482549, security.jail.param.sysvshm, node, N, Undefined 2147482851.2147482945.2147482932.2147482549.2147482548, security.jail.param.sysvshm., integer, E,jailsys, Defined 2147482851.2147482945.2147482932.2147482560, security.jail.param.sysvsem, node, N, Undefined 2147482851.2147482945.2147482932.2147482560.2147482559, security.jail.param.sysvsem., integer, E,jailsys, Defined 2147482851.2147482945.2147482932.2147482573, security.jail.param.sysvmsg, node, N, Undefined 2147482851.2147482945.2147482932.2147482573.2147482572, security.jail.param.sysvmsg., integer, E,jailsys, Defined 2147482851.2147482945.2147482932.2147482900, security.jail.param.allow, node, N, Undefined 2147482851.2147482945.2147482932.2147482900.2147482888, security.jail.param.allow.mount, node, N, Undefined 2147482851.2147482945.2147482932.2147482900.2147482888.2147471913, security.jail.param.allow.mount.debugfs, integer, B, Defined 2147482851.2147482945.2147482932.2147482900.2147482888.2147471916, security.jail.param.allow.mount.anon_inodefs, integer, B, Defined 2147482851.2147482945.2147482932.2147482900.2147482888.2147473599, security.jail.param.allow.mount.devfs, integer, B, Defined 2147482851.2147482945.2147482932.2147482900.2147482888.2147473671, security.jail.param.allow.mount.tmpfs, integer, B, Defined 2147482851.2147482945.2147482932.2147482900.2147482888.2147473673, security.jail.param.allow.mount.procfs, integer, B, Defined 2147482851.2147482945.2147482932.2147482900.2147482888.2147482887, security.jail.param.allow.mount., integer, B, Defined ... 2147482851.2147482945.2147482932.2147482904, security.jail.param.ip6, node, N, Undefined 2147482851.2147482945.2147482932.2147482904.2147482901, security.jail.param.ip6.saddrsel, integer, B, Defined 2147482851.2147482945.2147482932.2147482904.2147482902, security.jail.param.ip6.addr, opaque, S,in6_addr,a, Defined 2147482851.2147482945.2147482932.2147482904.2147482903, security.jail.param.ip6., integer, E,jailsys, Defined 2147482851.2147482945.2147482932.2147482908, security.jail.param.ip4, node, N, Undefined 2147482851.2147482945.2147482932.2147482908.2147482905, security.jail.param.ip4.saddrsel, integer, B, Defined 2147482851.2147482945.2147482932.2147482908.2147482906, security.jail.param.ip4.addr, opaque, S,in_addr,a, Defined 2147482851.2147482945.2147482932.2147482908.2147482907, security.jail.param.ip4., integer, E,jailsys, Defined 2147482851.2147482945.2147482932.2147482910, security.jail.param.cpuset, node, N, Undefined 2147482851.2147482945.2147482932.2147482910.2147482909, security.jail.param.cpuset.id, integer, I, Defined 2147482851.2147482945.2147482932.2147482916, security.jail.param.host, node, N, Undefined 2147482851.2147482945.2147482932.2147482916.2147482911, security.jail.param.host.hostid, unsigned long, LU, Defined 2147482851.2147482945.2147482932.2147482916.2147482912, security.jail.param.host.hostuuid, string, A, Defined 2147482851.2147482945.2147482932.2147482916.2147482913, security.jail.param.host.domainname, string, A, Defined 2147482851.2147482945.2147482932.2147482916.2147482914, security.jail.param.host.hostname, string, A, Defined 2147482851.2147482945.2147482932.2147482916.2147482915, security.jail.param.host., integer, E,jailsys, Defined 2147482851.2147482945.2147482932.2147482919, security.jail.param.children, node, N, Undefined 2147482851.2147482945.2147482932.2147482919.2147482917, security.jail.param.children.max, integer, I, Defined 2147482851.2147482945.2147482932.2147482919.2147482918, security.jail.param.children.cur, integer, I, Defined ...
