#20399: /etc/config/network, bridge, ifname multiple @interfaces
---------------------------------------+-----------------------------------
Reporter: gongtao0607@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Barrier Breaker 14.07
Component: base system | Version: Barrier Breaker 14.07
Keywords: uci network bridge ifname |
---------------------------------------+-----------------------------------
Very interesting behaviour of handling multiple "@" in the ifname list of
a bridge.
Here's my configuration
---------------------------------
config interface 'lan'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option stp '1'
option ifname '@a_b.1 @a_c.1 eth0.1 eth1'
config interface 'a_b'
option proto 'gretap'
option peeraddr '137.99.11.230'
option mtu '1458'
option zone 'lan'
config interface 'a_c'
option proto 'gretap'
option peeraddr '137.99.10.203'
option mtu '1458'
option zone 'lan'
---------------------------
After /etc/init.d/network restart, the brctl show gives me:
root@OpenWrt-A:~# /etc/init.d/network restart
'radio0' is disabled
root@OpenWrt-A:~# brctl show
bridge name bridge id STP enabled interfaces
br-lan 7fff.c63dc7af1f22 yes eth0.1
eth1
wlan1
gre-a_b.1
Which is missing @a_c.1.
With either '@a_b.1 eth0.1 eth1' or '@a_c.1 eth0.1 eth1' it works
perfectly, but not both.
What I guess is that the network script only handle the first @interface.
However, the interesting thing is, if I do a "/etc/init.d/network reload",
they both appear to be there!
root@OpenWrt-A:~# /etc/init.d/network reload
'radio0' is disabled
'radio0' is disabled
root@OpenWrt-A:~# brctl show
bridge name bridge id STP enabled interfaces
br-lan 7fff.c63dc7af1f22 yes eth0.1
eth1
wlan1
gre-a_b.1
gre-a_c.1
My device is Netgear WNDR3700v2, I think it is reproducible on other
device.
To conclude:
Multiple @interface in the ifname of bridge.
After /etc/init.d/network restart, only the first @interface showed up in
the bridge
After /etc/init.d/network reload, both appear
After boot, same as a restart.
