I agree with this.  Debian-installer should not create a network
configuration that depends on tools that have been deprecated for over
a decade.

Currently the vlan package provides such hooks.  No reason one could
not add such hooks to the iproute2 package or even extend ifupdown to
handle it itself.  Using the vlan package is certainly not efficient
compared to using the ip command for the job.  This is also true for
bridge-utils as far as I know, where I think iproute2 can also completely
replace that.

I know that. vlan package is needed for the ifupdown hooks to parse
vlan stanza from /etc/network/interfaces and hence configure vlan id.
Or am I missing something?

You don't need vlan; iproute2's ip can do it:

ip link add link eth0 name vlan9 type vlan id 9
or
ip link add link eth0 name eth0.9 type vlan id 9

OMG, I just had to go through vlan pain, and *anything* would be
better than current situation, rewrite or not.

One thing I see missing is that apart from writing out correct
/etc/network/interface one also needs to install "vlan" package in the
target installation. Is this done somewhere?

Apart from that nit-pick, this is amazing, and I'm feeling like just
finally merging this.

Dimitri.

Hi,

We're really interested in this, where should we look for a status
update? I still do not see an option for it in the installer for Wheezy,
so I guess it's not done yet. Will it be present for Jessie? Anything we
can do to help?

Thanks for Zhengpeng Hou, who points out that I leave a piece of code which is
not used anymore in this patch. This piece of code make a more malloc while not
free.

And I refresh this patch with the current git.
This is the new patch.

Any one has progress on rewriting it?

I might have considered something “already-suitable” for inclusion
into rc2 or something, but since a rewrite is suggested by Philipp, it
looks like the backport solution looks the way to go (at least Aron is
OK with Philipp's proposal).

 I'd say that this is something that must be preseeded and if
 anything it would show errors in English. So I'm not too concerned
 about that. But if we agree that it is useful to show
 netcfg/use_vlan in jessie in expert mode, we can do that too.

ACK.

 It needs a rewrite, IMHO. I started reviewing / rewriting it, but I'm not
 stopping others to work on it. (More debugging output, more sane memory
 handling, coding style adjustments.)

 I'm not sure I get to it before the next rc, though. At least, if it
 works, it could probably also be backported to wheezy's d-i if it's too
 late. It's pretty self-contained.


Thank you for working on this, and sorry for my not able to provide more help.

I don't expect it to be included to Wheezy in current stage of freeze,
and a backport will work. I work part-time in an IDC and the needs of
some not-so-common usages (like vlan support in d-i) are obvious to
me. Replacing some of RHEL/CentOS installations with Debian helps
quite a log in daily operation, but this gives me some chances to find
problems and help on improving Debian in such environments.

It would be handy if the option is shown if vlan udeb is selected when
choosing additional functions during installation, but I doubt whether
this can apply for kBSD as they seem to have vlan support built-in to
the kernel. Also hurd does not support 8021q vlan yet, showing the
option does not make sense for it.

Hi,

The Linux kernel's vlan udeb is added in linux/3.2.35-1, so there is
no outside thing to block us from adding vlan support to netcfg, can

In my opinion, this should go into a jessie branch, in netcfg.

I'm sending a reminder on this issue, it would be best if d-i can
support VLAN using expert mode of installation, configuring VLAN using
iproute2 during installation is much more annoying comparing to
configure it within d-i.

A reminder is nice and if you are luck might get things started, but
as you probably know, d-i is free software. Pachtes are most welcome.
Everyone is free to contribute and I don't know of any technically sound
contribution to d-i that has been turned down.

The code is at git.debian.org, the components you probably need to
modify are netcfg and busybox (to enable VLAN support).

Thanks, I know that, and I have been a Debian contributor for quite
some time, :-)

IIRC busybox-udeb has enabled VLAN support, the only thing left is
netcfg. But to be honest I'm not familiar with those stuff...

It depends on which level we support vlans.  I see two options:
 * full support with the debconf questions and proper scripts,
 * only make the necessary udebs available and a good documentation on
   how to enable vlans through a shell.

In my opinion, people who would like to enable VLAN should be pretty
used to the command-line (network switches are usually configured that
way), so the later would be enough, IMHO.

  vlan support in the installer would avoid this reconfiguration.

 (Please provide pointer to vlan support in debian)

Please look into the vlan [1] package for the necessary command line
tools.  Kernel support is provided by the 8021q module, available in
standard Debian kernel.

[1] http://packages.debian.org/vlan

Once the vlan package is installed, I just need to write something like:

  iface eth0.42 inet dhcp

This will configure an interface named eth0.42, using the physical
link connected on eth0 and tagging packets with VLANID 42.

So in any case, we would need to recognize if such interface is used
during the installation process to install the vlan package in the
target.

[Luca Filipozzi]

Package: debian-installer
Severity: wishlist

Please consider adding vlan support to debian-installer.  There are
cases (edge cases, admitedly) where machines and switches have been
configured to use vlan tagging.  A reinstall of these machines requires
a network reconfiguration.  vlan support in the installer would avoid
this reconfiguration.  Thanks for reading this far.
