Encapsulate SYSV IPC objects in jails. Define per-module parameters sysvmsg, sysvsem, and sysvshm, with the following bahavior:
inherit: allow full access to the IPC primitives. This is the same as the current setup with allow.sysvipc is on. Jails and the base system can see (and moduly) each other's objects, which is generally considered a bad thing (though may be useful in some circumstances).
disable: all no access, same as the current setup with allow.sysvipc off.
new: A jail may see use the IPC objects that it has created. It also gets its own IPC key namespace, so different jails may have their own objects using the same key value. The parent jail (or base system) can see the jail's IPC objects, but not its keys.

Allow the kern.osrelease and kern.osreldate sysctl values to be set in a jail's creation parameters. This allows the kernel version to be reliably spoofed within the jail whether examined directly with sysctl or indirectly with the uname -r and -K options.
The values can only be set at jail creation time, to eliminate the need for any locking when accessing the values via sysctl.
The overridden values are inherited by nested jails (unless the config for the nested jails also overrides the values).
There is no sanity or range checking, other than disallowing an empty release string or a zero release date, by design. The system administrator is trusted to set sane values. Setting values that are newer than the actual running kernel will likely cause compatibility problems.

Added support for extra ifconfig args to jail ip4.addr & ip6.addr params
This allows for CARP interfaces to be used in jails e.g. ip4.addr = "em0|10.10.1.20/32 vhid 1 pass MyPass advskew 100"
Before this change using exec.prestart to configure a CARP address would result in the wrong MAC being broadcast on startup as jail creates IP aliases to support ip[4|6].addr before exec.prestart is executed.

allow.mount.nullfs: allow mounting the nullfs filesystem inside a jail
Both parameters are disabled by default (equals the behavior before devfs and nullfs in jails). Administrators have to explicitly allow mounting devfs and nullfs for each jail. The value "-1" of the devfs_ruleset parameter is removed in favor of the new allow setting.

Jails have a problem in that if the jail directory is world-readable, an attacker with root access to the jail can create a setuid binary for their own use in the host environment (if they also have this access), thus breaking root in the host.
This exploit is impossible if the jail's files are not world-readable. Add instructions to the man page on how to create a jail with the correct permissions set.

Add ip4.saddrsel/ip4.nosaddrsel (and equivalent for ip6) to control whether to use source address selection (default) or the primary jail address for unbound outgoing connections.
This is intended to be used by people upgrading from single-IP jails to multi-IP jails but not having to change firewall rules, application ACLs, ... but to force their connections (unless otherwise changed) to the primry jail IP they had been used for years, as well as for people prefering to implement similar policies.
Note that for IPv6, if configured incorrectly, this might lead to scope violations, which single-IPv6 jails could as well, as by the design of jails. [1]

Place hostnames and similar information fully under the prison system. The system hostname is now stored in prison0, and the global variable "hostname" has been removed, as has the hostname_mtx mutex. Jails may have their own host information, or they may inherit it from the parent/system. The proper way to read the hostname is via getcredhostname(), which will copy either the hostname associated with the passed cred, or the system hostname if you pass NULL. The system hostname can still be accessed directly (and without locking) at prison0.pr_host, but that should be avoided where possible.
The "similar information" referred to is domainname, hostid, and hostuuid, which have also become prison parameters and had their associated global variables removed.

MFp4: Bring in updated jail support from bz_jail branch.
This enhances the current jail implementation to permit multiple addresses per jail. In addtion to IPv4, IPv6 is supported as well. Due to updated checks it is even possible to have jails without an IP address at all, which basically gives one a chroot with restricted process view, no networking,..
SCTP support was updated and supports IPv6 in jails as well.
Cpuset support permits jails to be bound to specific processor sets after creation.
Jails can have an unrestricted (no duplicate protection, etc.) name in addition to the hostname. The jail name cannot be changed from within a jail and is considered to be used for management purposes or as audit-token in the future.
DDB 'show jails' command was added to aid debugging.
Proper compat support permits 32bit jail binaries to be used on 64bit systems to manage jails. Also backward compatibility was preserved where possible: for jail v1 syscalls, as well as with user space management utilities.
Both jail as well as prison version were updated for the new features. A gap was intentionally left as the intermediate versions had been used by various patches floating around the last years.
Bump __FreeBSD_version for the afore mentioned and in kernel changes.
Special thanks to: - Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches and Olivier Houchard (cognet) for initial single-IPv6 patches. - Jeff Roberson (jeff) and Randall Stewart (rrs) for their help, ideas and review on cpuset and SCTP support. - Robert Watson (rwatson) for lots and lots of help, discussions, suggestions and review of most of the patch at various stages. - John Baldwin (jhb) for his help. - Simon L.

Add security.jail.mount_allowed sysctl, which allows to mount and unmount jail-friendly file systems from within a jail. Precisely it grants PRIV_VFS_MOUNT, PRIV_VFS_UNMOUNT and PRIV_VFS_MOUNT_NONUSER privileges for a jailed super-user. It is turned off by default.
A jail-friendly file system is a file system which driver registers itself with VFCF_JAIL flag via VFS_SET(9) API. The lsvfs(1) command can be used to see which file systems are jail-friendly ones.
There currently no jail-friendly file systems, ZFS will be the first one. In the future we may consider marking file systems like nullfs as jail-friendly.

Add a new sysctl, "security.jail.chflags_allowed", which controls the behaviour of chflags within a jail. If set to 0 (the default), then a jailed root user is treated as an unprivileged user; if set to 1, then a jailed root user is treated the same as an unjailed root user.
This is necessary to allow "make installworld" to work inside a jail, since it attempts to manipulate the system immutable flag on certain files.

Add a warning note to security.jail.allow_raw_sockets about the risks of enabling raw sockets in prisons.
Because raw sockets can be used to configure and interact with various network subsystems, extra caution should be used where privileged access to jails is given out to untrusted parties. As such, by default this option is disabled.
A few others and I are currently auditing the kernel source code to ensure that the use of raw sockets by privledged prison users is safe.

A variety of content cleanups:
(1) Document the notion of using jail(8) to run "virtual servers" or just to constrain specific applications. If only running specific applications, some configuration steps are unnecessary (such as editing rc.conf).
(2) Add some more subsection headers to break up the bigger chunks of text.
(3) Clarify the problems associated with applications binding all IP addresses in the host, and attempt to be more specific about potential application problems. Document how to force sshd to bind the the right socket.
(4) Suggest that in a jailed application scenario, you might want to have the host syslogd listen on the socket in the jail, rather than running syslogd in the jail.
(5) Catch another reference to /stand/sysinstall.

When pointing users at mount_devfs to populate the /dev of a jail, tell them that they also need to use devfs rules to prevent inappropriate devices from appearing in the jail; add an Xref. In earlier versions of this man page, the user was instructed to use sh MAKEDEV jail, which only created a minimal set of device nodes.

Change NO_MAKEDEV to a finer granularity method: NO_MAKEDEV_INSTALL and NO_MAKEDEV_RUN. The former implying the latter. The names imply what they do. The last commit by DES based on a PR defeated the original idea behind NO_MAKEDEV, which was not to run MAKEDEV, but to do the installation of MAKEDEV. This should satisfy both parties on the MAKEDEV challenge. Reflect this in the documentation.

- As jail(8) has been almost completely rewritten, prepend another copyright/ BSD-style license, as an add-on to phk's beerware license. Please fedex some beer to phk.
- Add a ``make depend'' line to the jail-building, which fixes openssl, among other things. Suggested by: kris
- Add ``newaliases'' to the list of things to do when setting up a new jail, so that the jailed sendmail doesn't complain.
- Correct references to ``kern.jail.set_hostname_allowed'' which now read ``jail.set_hostname_allowed''.

Clean up the jail(8) documentation so that it suggests building a jail userland in a safer way. Using the NO_MAKEDEV argument in make distribution prevents the creation of a number of unsafe device nodes in the jailed /dev, including disk devices, and more. This depends on an earlier commit to /etc/Makefile to provide the NO_MAKEDEV support.

This Implements the mumbled about "Jail" feature.
This is a seriously beefed up chroot kind of thing. The process is jailed along the same lines as a chroot does it, but with additional tough restrictions imposed on what the superuser can do.
For all I know, it is safe to hand over the root bit inside a prison to the customer living in that prison, this is what it was developed for in fact: "real virtual servers".
Each prison has an ip number associated with it, which all IP communications will be coerced to use and each prison has its own hostname.
Needless to say, you need more RAM this way, but the advantage is that each customer can run their own particular version of apache and not stomp on the toes of their neighbors.
It generally does what one would expect, but setting up a jail still takes a little knowledge.
A few notes:
I have no scripts for setting up a jail, don't ask me for them.
The IP number should be an alias on one of the interfaces.
mount a /proc in each jail, it will make ps more useable.
/proc/<pid>/status tells the hostname of the prison for jailed processes.
Quotas are only sensible if you have a mountpoint per prison.
There are no privisions for stopping resource-hogging.
Some "#ifdef INET" and similar may be missing (send patches!)
If somebody wants to take it from here and develop it into more of a "virtual machine" they should be most welcome!
Tools, comments, patches & documentation most welcome.
Have fun...
