94d77159ae 1. New feature; option to have the script loop until a specified hostname
(localhost by default) can be successfully looked up. Off by default.
2. New feature: option to create a forwarder configuration file based on
the contents of /etc/resolv.conf. This allows you to utilize a local
resolver for better performance, less network traffic, custom zones, etc.
while still relying on the benefits of your local network resolver.
Off by default.
3. Add named-checkconf into the startup routine. This will prevent named
from trying to start in a situation where it would not be possible to do
so.

507fe729a1 Named normally cannot be started chrooted inside a jail. Thus treat
the jail case specifically. In case we find a proper pre-seeded
devfs in the chroot path (mounted from the base system) permit
starting chrooted else give proper warn/error messages.

3c9471138e 1. Determine the location of the rndc* binaries relative to $command
so that when using named from the ports (or elsewhere) the proper rndc*
commands will be run.

2. Rework the stop routine using ideas from brooks and delphij.
Specifically I am duplicating a lot of code from rc.subr's stop routine
so that this one will behave more like the one in rc.subr, but use rndc
to kill the daemon (or regular kill if that fails). This also avoids
the problems related to using killall if rndc fails, which is bad if
you're running more than one named on the same box.

3. Take a concept from gshapiro and allow the rndc.key file to be
owned by root OR the named_uid user.

Although I used different solutions, this commit handles issues raised in:

196b6a193e Overhaul the named boot script:
1. Remove a now-spurious NetBSD CVS Id, as we are no longer synching work
2. Remove a now-spurious BEFORE, since ntpdate now REQUIRE's named
3. Replace the call to set rcvar with what that function would output,
and generally reduce indirection ($name -> named) since it's highly
unlikely the name of the named process or service will change any time soon.
4. Resort the order the variables at the top of the file to a more
traditional format, and remove a spurious required_dirs from the top, as it
works better after load_rc_config.
5. We do not want the default reload method with named, so define a simple
but appropriate substitute using rndc. If I were writing this script for
the first time I would not include this at all, since it's preferable to
control a running daemon with rndc to start with, but given that this is
already here, let's do it right. I hope that future generations will
however resist the tempation to add reconfig to extra_commands.
6. By the same token, we want to use rndc to shut down named, but given
that by defining a stop function we lose the "find the process by its
pid file in an emergency" goodness of rc.subr, try to do something useful
in the event that rndc is not available, and keep the user informed.
7. Replace some "test -f" with "test -r" to handle the unlikely event
that the relevant file exists, but is unreadable.
8. Twiddle whitespace in a few areas, remove a spurious blank line,
a bogus double space, and try to do better indenting.
9. Improve generation of the rndc.key file significantly
a. If for some reason a user has an rndc.conf file, assume that they
did that on purpose, and hence know what they are doing, so leave them alone.
b. Introduce a named_uid configuration variable so that the user which owns
the rndc.key file and the user named runs as always match, and is more
easily configurable. This should dramatically reduce problems with rndc.
c. Also test that the rndc.key file size is greater than zero, rather than
simply that the file exists. I have seen at least one user report this exact
problem, and although neither of us is sure where the empty file came from,
the fix is simple, so include it.
d. Rather than try to create an rndc.key file in both /etc/namedb and the
chroot'ed /etc/namedb, assume that they are be the same (which they should
be), and only create the file in the chroot'ed version of the directory.
This partially addresses the problem described in conf/73929, but I have
not yet finished thinking about the PREFIX issue that PR also raises.

As a result of introducing the named_uid knob, the default named_flags
are now empty.

Update defaults/rc.conf and rc.conf(5) to reflect these changes.

180e996dfc Don't be lazy, set the "command" variable even if
/etc/defaults/rc.conf will provide foo_program, too.
By specifying "command" we explicitly say that we're
going to rely on rc.subr(8) default methods, and
rc.subr(8) will take advantage of this soon.

The majority of our rc.d scripts already set "command"
if appropriate, so fix just the non-compliant handful.

8f5aed3be4 We need to use 'applyset' command for devfs, 'apply hide' is not enough,
because new devfs entries can show up later and one can access such entires
from inside named chroot.
In rc.d scripts we can use devfs_domount() function with devfsrules_hide_all
policy and unhide 'null' and 'random' manually.

65db76c1aa Add -h to the ln command to make the -f flag actually do something.
Without this flag, if the symlink existed already a new symlink would
be created in the source directory. While harmless if the two symlinks
were the same, it nonetheless caused pointless confusion.

The pathological case is that when there is an existing /etc/namedb
symlink, but named_chrootdir in rc.conf pointed to a different
directory, it was the symlink in /var/named that was getting
updated, not the one in /etc. This led to some difficult to diagnose
problems for users.

8f1bb3891d Create a named chroot directory structure in /var/named, and use it
by default when named is enabled. Also, improve our default directory
layout by creating /var/named/etc/namedb/{master|slave} directories,
and use the former for the generated localhost* files.

Rather than using pax to copy device entries, mount devfs in the
chroot directory.

There may be some corner cases where things need to be adjusted,
but overall this structure has been well tested on a production
network, and should serve the needs of the vast majority of users.

UPDATING has instructions on how to do the conversion for those
with existing configurations.

fb9540a0dc Update to reflect BIND 9 in the base:
1. Making the pid symlink now has to happen after named starts, otherwise
it can generate a fatal error.

2. named-xfer is not part of the BIND 9 world.

3. BIND 9 needs a /dev/random in the chroot directory if chrooted.

4. Only the pid file is symlinked now, the ndc socket is BIND 8 only.

5. Create an rndc.key file for the user if one does not exist.
This (generally) allows a BIND 8 config file to be used in a BIND 9
world with little or no modification.

0a54defb08 1. Remove the named_rcng variable. Mike's caution in this area was a good
thing, but we're ready to move on.

2. Remove the -g default argument in named_flags. It doesn't actually do
what most users think it does, and what most users want it to do is already
accomplished with a proper default group for the bind user, which we have.
Also, the -g knob does something entirely different in BIND 9, which leads
to a lot of needless confusion/aggravation.

3. In the rc.d script, don't bogusly override $command, or $rc_flags. Both
are adequately handled in rc.conf[.local].

4. DO properly override $rc_flags if user has named_chrootdir set.
This may need to be revisited, but should be ok for now.

5. Protect all chrootdir-related bits under that variable, instead of
named_rcng.

There is more work to be done here, especially in the area of BIND 9
compatibility, but this is a start at least.
