Multiple IPv6 addresses of the same prefix can be installed on the
same interface. The first address will install the prefix route into
the kernel routing table and that prefix will be marked as on-link.
Without RADIX_MPATH enabled, the other address aliases of the same
prefix will update the prefix reference count but no other routes
will be installed. Consequently the prefixes associated with these
addresses would not be marked as on-link. As such, incoming packets
destined to these address aliases will fail the ND6 on-link check
on input. This patch fixes the above problem by searching the kernel
routing table and try to find an on-link prefix on the given interface.

The proxy arp entries could not be added into the system over the
IFF_POINTOPOINT link types. The reason was due to the routing
entry returned from the kernel covering the remote end is of an
interface type that does not support ARP. This patch fixes this
problem by providing a hint to the kernel routing code, which
indicates the prefix route instead of the PPP host route should
be returned to the caller. Since a host route to the local end
point is also added into the routing table, and there could be
multiple such instantiations due to multiple PPP links can be
created with the same local end IP address, this patch also fixes
the loopback route installation failure problem observed prior to
this patch. The reference count of loopback route to local end would
be either incremented or decremented. The first instantiation would
create the entry and the last removal would delete the route entry.

-------
The IFA_RTSELF address flag marks a loopback route has been installed
for the interface address. This marker is necessary to properly support
PPP types of links where multiple links can have the same local end
IP address. The IFA_RTSELF flag bit maps to the RTF_HOST value, which
was combined into the route flag bits during prefix installation in
IPv6. This inclusion causing the prefix route to be unusable. This
patch fixes this bug by excluding the IFA_RTSELF flag during route
installation.

Since the change to rc.subr in r198162 it's not necessary to specify

Fix a silly bug that would only have affected people who were using
the new named_wait or named_auto_forward features, AND had set up an

For named_conf:
Add "-c $named_conf" to command_args if it's not set to the
default. If it is set to the default and we're using the base
BIND it's not necessary. If we're using BIND from the ports
the user is likely to have included it in _flags (due to long
necessity for doing so) so don't duplicate that if it's set.
Add $named_conf to required_files
MFC r200563:
The named process needs to have a "working directory" that it can
write to. This is specified in "options { directory }" in named.conf.
So, create /etc/namedb/working with appropriate permissions, and
update the entry in named.conf to match.
In addition to specifying the working directory, file and path names
in named.conf can be specified relative to the directory listed.
However, since that directory is now different from /etc/namedb
(where the configuration, zone, rndc.*, and other files are located)
further update named.conf to specify all file names with fully
qualified paths. Also update the comment about file and path names
so users know this should be done for all file/path names in the file.
This change will eliminate the 'working directory is not writable'
messages at boot time without sacrificing security. It will also
allow for features in newer versions of BIND (9.7+) to work as
designed.
