Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

That it went this long without anyone noticing is a sign that this feature
isn't actually used by anyone, but it's there so it might as well work.

Right now if a jail has multiple IPv6 addresses, it will print them
shifting only 4 bytes at a time. Example:
2001:4dd0:ff41::b23f:a9
2001:4dd0:ff41::b23f:aa
Becomes:
2001:4dd0:ff41::b23f:a9
ff41::b23f:a9:2001:4dd0
By casting to in6_addr, it uses the correct offsets.

and jail_get(2). Jail(8) can now create jails using a "name=value"
format instead of just specifying a limited set of fixed parameters; it
can also modify parameters of existing jails. Jls(8) can display all
parameters of jails, or a specified set of parameters. The available
parameters are gathered from the kernel, and not hard-coded into these
programs.
Small patches on killall(1) and jexec(8) to support jail names with
jail_get(2).

When checking if there is a name configured for the prison, check the
first character to not be '\0' instead of checking if the char array
is present, which it always is. Note, that this is different for the
*jailname in the syscall.

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.

in sysctl_jail_list(). Because of this, jls(8) could enter into
an endless loop. The strange thing is, that we can call jls(8) while
the other one is in loop and it will succeed - SYSCTL_OUT() will
not return ENOMEM there.
Maybe SYSCTL_OUT() returns first ENOMEM, because there is no memory,
but is marking some memory range as wired even on failure and another
SYSCTL_OUT() calls are not going to succeed, because process exceeds
limit of wired memory? ENOVMCLUE.
Anyway. Fix jls(8) to ignore ENOMEM and retry only 4 times.
