Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
Please unblock package ifupdown-extra
[ Reason ]
There is a bug (#987310) in the package in testing which prevents the
static-routes script (/etc/network/if-up.d/20static-routes) from working
properly when the package is configured to include them.
I have also taken the opportunity to:
- fix the script so it exits gracefully if called directly (i.e.
when the interface to act on is not set)
- fix the script so that the 'status' check works properly when the gateways
have a defined name in the /etc/hosts
- update the documentation (README) to warn users about the behaviour of one
script.
[ Impact ]
If the package is not unblocked users installing this package and trying to set
static routes will have their routes added to the 'blackhole' configuration
instead.
[ Tests ]
Tested locally in developer's machine with different configuration variations.
The script runs as expected (adding, removing and checking the status
of routes added in /etc/network/routes
[ Risks ]
Changes in the package are trivial, there is very low risk
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing

+Network link checks
+------------------
+
+The script that tests the network link is run inmediately after an interface is
+administratively configured up. However, the underlying hardware sometime it
+takes some time to establish and negotiate a link. This is heavily dependant on
+the hardware itself and the system it is connected to (e.g. if auto negotiation
+of an interface is enabled or the duplex/mode are forced in the interface).
+
+Due to this time interval for the link to fully stablise it is possible that
+the check-network-cable might generate false negative error messages on
+systems.
+
+If this is your case, you are encourage to disable the script by editing
+/etc/default/network-test and changing the variable DO_CABLETEST to 'no'
