Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match. I *believe* this is fixed in the current rawhide initscripts. Please try with 8.08-1 or so. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Description of problem: Original symptoms were problems booting/shutting down; on boot, pcmcia start would hang. On shutting down, network stop would hang on bringing down the wireless ethernet interface. This occurred only when using a different interface card than specified in the network configuration. Problem traced to infinite recursion of /sbin/ifdown due to a test block around line 60: if [ -n "${HWADDR}" -a -z "${MACADDR}" ]; then FOUNDMACADDR=`get_hwaddr ${REALDEVICE}` if [ "${FOUNDMACADDR}" != "${HWADDR}" ]; then NEWCONFIG=`fgrep -il "HWADDR=${HWADDR}" /etc/sysconfig/network-scripts/ifcfg-*` if [ -n "${NEWCONFIG}" -a "${NEWCONFIG}" != "${CONFIG}" ]; then exec /sbin/ifdown ${NEWCONFIG} else echo $"Device ${DEVICE} has different MAC address than expected, ignoring." exit 1 fi fi fi Cause of the problem in this script is that if a network card with a different HW address than in the configs is used, then the inner test succeeds recursively. Looking at ifup seems to indicate that this condition should not be reached, as the ifup script should check that the HW address of the card matches the specified address in the configuration - this is probably the real cause of the problem. I haven't figured out why ifup doesn't succeed at this though. Version-Release number of selected component (if applicable): initscripts-7.53-1 How reproducible: Always Steps to Reproduce: 1. Configure a wireles interface using the appropriate MAC address 2. Use a different card of the same type to bring up the interface (For me, it was 2 orinoco gold cards) 3. Unplug the card, or try to shutdown. Actual Results: After unplugging the card, top showed ifdown hanging. Expected Results: Depends on what the design was - I suppose that ifup should have stopped the interface from coming up in the first place, so this result should not have been reached at all.
