Description Olivier Fourdan 2009-05-19 11:32:05 EDT
Description of problem:

system-config-network uses the file route-${DeviceId} to save static routes defined in GUI.

However, that file may contain old custom style and system-config-network will remove the file upon save even if the route has not been modified in the GUI.

Version-Release number of selected component (if applicable):


How reproducible:

100% reproducible

Steps to Reproduce:
1. Create a "/etc/sysconfig/network-scripts/route-eth0" with options that system-config-network does not parse dev eth0 table 2
   default via 192.168.254 table 2 

2. Run system-config-network, modify a param for eth0 leaving the route untouched

3. Save
Actual results:

/etc/sysconfig/network-scripts/route-eth0 is removed

Expected results:

/etc/sysconfig/network-scripts/route-eth0 is left untouched

Additional info:

The file is removed NCDevice.py is save() by this portion of code:

260     def save( self ):
371         # FIXME: RFE [174974] limitation of setting routing
372         if self.StaticRoutes and len( self.StaticRoutes ) > 0:
373             rconf = ConfRoute( self.DeviceId )
374             for key in rconf.keys():
375                 del rconf[key]
376             p = 0
377             for route in self.StaticRoutes:
378                 if route.Address:
379                     rconf['ADDRESS'+str( p )] = route.Address
380                 if route.Netmask:
381                     rconf['NETMASK'+str( p )] = route.Netmask
382                 if route.Gateway:
383                     rconf['GATEWAY'+str( p )] = route.Gateway
384                 p = p + 1
385             rconf.write()
386         else:
387             # remove route file, if no routes defined
388             unlink( netconfpkg.ROOT + SYSCONFDEVICEDIR + self.DeviceId + '.route' )
389             unlink( netconfpkg.ROOT + SYSCONFDEVICEDIR + 'route-' + self.DeviceId )

As system-config-network has not parsed the existing option in the route-eth0 file, self.StaticRoutes is empty and therefore the unlink in invoked.
Comment 1 Harald Hoyer 2009-05-20 02:33:49 EDT
yes, bug. Easily fixable.
