Hi All, I have one netcf question, please help me to resolve it, thanks.
I can set a IFF_RUNNING flag to a bridge device which are no interface device attached. What status of a flag on a bridge device in current kernel?(w/o interface), is this a new change in kernel or other component? In netcf, but there is a patch to fix that flag issue, I can't understand it. fix wrong status of bridge devices The IFF_RUNNING flag is not set on a bridge device if there are no devices attached to it. So bridges without attached devices are reported as inactive. Destroying inactive devices leads to an error and thus the device can't be removed (easily) from the operating system. This patch checks if the device is a bridge and if so ignores the IFF_RUNNING flag. https://git.fedorahosted.org/cgit/netcf.git/commit/?id=7fa5fa5a1e43e6e2afec68c58b5f43bc916703a6 My testing results of IFF_RUNNING on non-device bridge: Version: [root@rhel6 boot]# rpm -q kernel netcf kernel-2.6.32-468.el6.x86_64 netcf-0.2.4-1.el6.x86_64 [root@rhel6 ~]# brctl show br0 bridge name bridge id STP enabled interfaces br0 8000.000000000000 no [root@rhel6 ~]# ifconfig br0 br0 Link encap:Ethernet HWaddr 6A:3B:6F:DF:17:A9 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:468 (468.0 b) [root@rhel6 ~]# ifconfig br0 up [root@rhel6 ~]# brctl show br0 bridge name bridge id STP enabled interfaces br0 8000.000000000000 no [root@rhel6 ~]# ifconfig br0 br0 Link encap:Ethernet HWaddr 6A:3B:6F:DF:17:A9 inet6 addr: fe80::683b:6fff:fedf:17a9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:11 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:866 (866.0 b) _______________________________________________ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
