Package: ifupdown
Version: 0.6.5
Severity: normal
Tags: Patch
The latest version of ifupdown has broken logical interface support as
follows:
"ifup -v eth0=work" produces:
| Suu:~# ifup -vvv eth0=work
| Configuring interface eth0=work (inet)
| run-parts --verbose /etc/network/if-pre-up.d
| run-parts: executing /etc/network/if-pre-up.d/wireless-tools
|
* ifconfig work 10.254.0.4 netmask 255.255.255.0 broadcast 10.254.0.255
up
| SIOCSIFADDR: No such device
| work: ERROR while getting interface flags: No such device
| SIOCSIFNETMASK: No such device
| SIOCSIFBRDADDR: No such device
| work: ERROR while getting interface flags: No such device
| work: ERROR while getting interface flags: No such device
| Failed to bring up work.
Obviously, the settings are coming from the work stanza OK, but surely
that should be
* ifconfig eth0 10.254.0.4 netmask 255.255.255.0 broadcast 10.254.0.255
up
?
Anyway, assuming I'm right, here's the patch:

if (strncmpz(id, ifd->option[i].name, idlen) == 0) {
Simply, the various references to %iface% in the .defn files are passed
to the system, so should be the real_iface (ie. what the system sees it
as) not logical_iface (ie. what the stanza's called)
If this is wrong, maybe ifrename should be being applied earlier in the
process? I can see how people might prefer the actual interface to end
up being called 'work' or 'home', but given how people object to
'wlanX', I doubt this would actually ever fly.
I'd love to mark this "Important" but when I asked on #debian if anyone
else had seen this, no one else seemed to be to using this
functionality.
Also, while I was poking around, checking for a preexisting bug report,
it looks like #244101 has been fixed by providing $LOGICAL to the if-*
scripts. Just thought I'd mention it, I haven't tested it or anything.
I just noticed the variable when I was tracking this problem through the
.nw file.
