I had the same problem, but is now fixed in initscripts-8.31.5-1. (And the correct component was initscripts, not bridge-utils.) If you use bridge iface name greater than bridge ports iface, it works. For example: I define a bridge zlan0 with eth0 and eth2 as its ports and this works. If I put "br0" instead "zlan0" don't works. Seems to work for me. Please provide more information about what happens when 'is_available br0' fails. It should already have created the bridge device by then. Does it work if you add a sleep after the 'brctl addbr' line? This is happening to me as well, initscripts 8.31.1-1. is_available br0 test never works. If I do "brctl addbr br0" then "ifup br0" it's fine. So, it would seem there's a new timing issue introduced in the initscripts package between FC4 and FC5. The brctl addbr code in ifup-eth isn't running before the is_available code in ifup, and the process is failing prematurely because of this. The timing issue seems code-flow related, not wall-clock related (e.g. adding a sleep doesn't help me). In /sbin/ifup, the is_available code is executed well before the OTHER_SCRIPT code runs /etc/sysconfig/network-scripts/ifup-eth, which is where the brctl code lives. And because there's no provision in /sbin/ifup prior to referencing is_available for TYPE=Bridge, it breaks. There are provisions, however, in /sbin/ifup for VLAN interfaces, and these are placed before the is_available check. Perhaps a function needs to be inserted before the is_available call in /sbin/ifup to check for TYPE=Bridge. I find it strange that the preparation for vlan configs is setup to run vconfig from /sbin/ifup, and that the preparation for bridging configs is setup run brctl from /etc/sysconfig/network-scripts/ifup-eth. I'd think we'd want them to happen at about the same time... the bonding code, the bridging code and the vlan code. Just my two cents. When will this be fixed? I am an idiot. This is fixed in initscripts 8.13.6-1. I should've paid closer attention to Luciano's comment. Can someone close this bug? I was given the impression this was still broken because the Status was New. |
Description of problem: In Fedora Core 5 the /etc/sysconfig/network-scripts/ifup-eth shell script has the flowing block of code: 82 # now check the real state 83 is_available ${REALDEVICE} || { 84 if [ -n "$alias" ]; then 85 echo $"$alias device ${DEVICE} does not seem to be present, delaying initialization." 86 else 87 echo $"Device ${DEVICE} does not seem to be present, delaying initialization." 88 fi 89 exit 1 90 } 91 92 # is the device wireless? If so, configure wireless device specifics 93 is_wireless_device ${DEVICE} && . ./ifup-wireless Located above the bridge creation code. The is_available check fails when looking for the virtual device br0, and therefore dies prior to the initialization of the bridge. Version-Release number of selected component (if applicable): Fedora Core 5 Vanilla Install from ISO How reproducible: This issue is always reproducible with the standard ifup-eth script. Steps to Reproduce: 1. run "service network stop" 2. Create /etc/sysconfig/network-scripts/ifcfg-br0 with the following DEVICE=br0 TYPE=Bridge BOOTPROTO=static IPADDR=192.168.1.2 NETMASK=255.255.255.0 ONBOOT=yes 3. Create /etc/sysconfig/network-scripts/ifcfg-eth0 with the following DEVICE=eth0 TYPE=Ethernet BRIDGE=br0 ONBOOT=yes 4. Create /etc/sysconfig/network-scripts/ifcfg-eth1 with the following DEVICE=eth0 TYPE=Ethernet BRIDGE=br0 ONBOOT=yes 5. run "service network start" Actual results: When initializing br0 the response is "Device br0 does not seem to be present, delaying initialization" and FAILED. Expected results: All OKs. Additional info: This issue does not occur on Fedora Core 4, and yum does not update this shell script. The issue appears to be contained to new installs of Fedora Core 5 only.
