Can you test the attached patch? The old version (in stable/9 now)
does not support "address range spec + options" properly and ignore
the options part.
The attached patch accepts options and treats "netmask" for inet and
"prefixlen" in inet6 in a reasonable way so that the specified
options do not conflict with the default /NN values.

I committed some descriptions about it to rc.conf(5) at the same
time. It is basically the same as ifconfig_IF_aliasN, but can have
multiple address specification. Both of ifconfig_IF_alias{N,es} now
supports range specification, so there is no difference in the
functionality. The following two examples give the same result:
ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0x"
ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0x"
ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0x"
ifconfig_ed0_alias3="inet 127.0.0.254 netmask 0x"
ifconfig_ed0_aliases="\
inet 127.0.0.251 netmask 0x \
inet 127.0.0.252 netmask 0x \
inet 127.0.0.253 netmask 0x \
inet 127.0.0.254 netmask 0x \
"
The implementation actually converts values in the variables in
ifconfig_IF_aliasN, ipv6_ifconfig_IF_aliasN, and ipv4_addrs_IF into a
list of them in a consistent format (AF-keyword + address spec +
options) used in ifconfig_IF_aliases, and then it processes
ifconfig_IF_aliases and them.
ifconfig_IF_aliasN accepts address spec without address family
keyword for backward compatibility, but ifconfig_IF_aliases does not.
This is the difference between the two.

I would actually prefer to see the ifconfig_IF_aliasN syntax go away
entirely as it simply cannot scale without becoming tedious. I know we
can't cover every edge case, but after discussing with people on this
list about the desire for ipv6_addrs_IF, now committed, it seems I'm not
the only example of this use case.
The best scenario I can describe is a situation where you have a shared
webhosting environment on FreeBSD. I may very well have 200 IPs on one
server. Being able to use ranges and CIDR syntax is invaluable. The idea
of ifconfig_IF_aliasN is not so bad as long as you never have to make
any changes. However, it's not uncommon to receive a work order from
sales where a customer needs to be moved from the shared webhosting
environment to their own private VM. We need to move the IP they were
using as we probably do not control DNS and it might be difficult for
the customer to get that changed. Removing an IP from the middle of 200
ifconfig_IF_aliasN entries requires you to renumber them all. This is
simply cruel and error-prone. Being able to adjust the ranges of
ipv4_addrs_IF is much cleaner and reliable.
This thread isn't exactly the proper forum to debate the future of
network configuration on FreeBSD, but please take this into
consideration. And thank you for your work on the rc.d scripts --
they're the #1 reason many of us prefer working with FreeBSD.

Hello,
Does this work on stable/9 or only on current ? If not, are there
any plans to MFC ? I ask because I don't see the

Thanks for this by the way - it _greatly_ simplifies rc.conf

The recommended way is ifconfig_IF_aliasN or ifconfig_IF_aliases.
ipv4_addr_IF will not be removed in the near future, but please use
ifconfig_IF_alias{N,es} for newly-configured systems. Backward
compatibility for not breaking the existing configurations will be
maintained as much as possible (even on the upcoming 10.0R and
later).
This is because we have a lot of variables which have (almost) the

them with each other, not because these are better than the others.
Variables with overlapped functionality have made difficult to
maintain/improve the rc.d scripts.

Sorry to resurrect this thread but since nothing has happened in about
three months I have to ask: What can I do to have this commited to

required. I feel that I'm compentent enough. Who can I contact?

I've been waiting for this for a while, as it will greatly simplify my rc.conf on a whole bunch of jail hosts. I've spoken with bz@ about this at eurobsdcon in November 2011 and he agreed that it is a missing feature, so I suspect it is a matter of time before your patch is picked up by a committer. Thank you for your work!

It can now be applied at top level of sources (/usr/src typically). It now does the deconfiguration in reverse order of the configuration, meaning the aliases configured with ipv6_addrs_IF are removed before the ones configured with ifconfig_IF_aliasN="inet6 ...". Also as noted in my previous message it's possible to configure all IPv6 addresses with a single ipv6_addrs_IF line in rc.conf: ipv6_addrs_re0="2001:db8::::1-4/64" I consider this version of the patch pretty much completed work. It applies cleanly to HEAD version r244694 and I don't see why it wouldn't work in HEAD as well. Now, is there any interest in seeing this feature as part of future versions of FreeBSD? Could it be incorporated to HEAD and then MFC'ed to 9-STABLE if it turns out it's seen as a useful feature?

So it looks like this: The documented way to do this is to just set the link-local address in ifconfig_IF_ipv6, since an interface is required to have a link-local address. Either configure an fe80:: address explicitly or set ifconfig_em0_ipv6="inet6 auto_linklocal" Alternatively, if you set ipv6_activate_all_interfaces all interfaces will be considered IPv6-capable.

It is attached in this message. Again it's against a very recent 9-STABLE, I still haven't found time to see if it applies to CURRENT. It does allow you to do crazy stuff like ipv6_addrs_re0="2001:db8::::1-/64" However I didn't find anything to limit the number of aliases in the ipv4 version of the function either.

You cannot assume that /usr/bin is available when setting up the network. It may be that /usr is mounted via NFS. You can use hexadecimal numbers (prefixed with 0x) in $((...)) expressions.

Thanks, I've rewitten my patch to support ranges. It is attached in
this message.
Again it's against a very recent 9-STABLE, I still haven't found time
to see if it applies to CURRENT.
It does allow you to do crazy stuff like
ipv6_addrs_re0="2001:db8::::1-/64"
However I didn't find anything to limit the number of aliases in the
ipv4 version of the function either.
Please test it :)
Then a question about the PR
(http://www.freebsd.org/cgi/query-pr.cgi?pr=174225) I wrote, how can I
attach this new patch to it? The submit follow up -button fires up my
email client and I'm not so sure how to submit a new patch for the PR
in an email in such a way that it appears properly formatted in the
PR.
