Description Lucas Maneos (reporter) 2010-01-07 08:22:20 UTC

SOFTWARE VERSION:
2.2009.51-1

EXACT STEPS LEADING TO PROBLEM: 
1. Put the following in /etc/network/if-up.d/test:

   #!/bin/sh
   env >> /tmp/test.log

2. chmod +x /etc/network/if-up.d/test
3. Establish a GPRS connection
4. egrep 'IFACE|LOGICAL' /tmp/test.log

EXPECTED OUTCOME:

LOGICAL=gprs0
IFACE=gprs0

ACTUAL OUTCOME:

LOGICAL=
IFACE=

REPRODUCIBILITY:
Always.

OTHER COMMENTS:
The same issue is observer with if-down.d, but I didn't test if-pre-up.d &
if-post-down.d.  For WLAN connections it works as expected:

LOGICAL=wlan0
IFACE=wlan0

Comment 1 Frederik Niedernolte 2010-01-08 09:27:39 UTC

I can confirm this (see bug 7731).

Comment 2 Aymeric Brisse 2010-02-17 13:06:14 UTC

I can confirm this too.

Comment 3 Robin 2010-03-09 15:45:54 UTC

Confirming bug with the above script with latest release.
10 test runs connecting/disconnecting gprs, all with the same result.

Comment 4 Aymeric Brisse 2010-05-11 19:21:32 UTC

if-pre-up.d scripts have always empty IFACE and LOGICAL values when connecting
to any network (GPRS or Wifi).

if-post-down.d scripts have empty IFACE and LOGICAL values when connecting to
GPRS.

When this bug will be fixed? Very annoying when developping network-related
applications.

Internal comment by Nokia:
"Fixing this could happen in 3 different places and none of them is trivial.
Simple solution of assuming gprs0 does not bring any value as it not guaranteed
to be the correct value."

Hence for Nokia this is a WONTFIX for Maemo5 currently.
Don't know about Maemo6 yet hence not closing yet as WONTFIX.

Fixed in libicd-network-gprs for Harmattan.
WONTFIX for Maemo5.
