Bridge PiCore
« on: June 10, 2015, 05:52:13 AM »
Is there a complete set of modules available for download?  piCore 6.1-beta1   (armv6)     or can we get an extension with the Kernel modules for Bridging?   

Also need the utilities: brctl and ebtables

Didn't think to look in the release folder.  Thanks

I grabbed the modules.......and made an extension and loaded it.

The bridge kernel module loads....that's a good start.   bridge.ko depends on llc.ko and stp.ko

But I wouldn't waste your time for the moment.   Seems that wifi-eth bridgeing is just too glitchy, with stock drivers and kernel.   

I'm going to test with a full Raspbian distribution before trying to proceed with piCore

Well after reading about so many failures, I have it working under the latest Raspbian,   Now to get it working under piCore.

Other than a wpa_supplicant.conf, this is the only thing needed.  in raspbian.   

/etc/network/interfaces
Code: [Select]
auto lo
iface lo inet loopback

iface eth0 inet manual

auto wlan0
iface wlan0 inet manual

wpa-iface wlan0
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

auto br0
iface br0 inet dhcp
   bridge_ports wlan0 eth0
   bridge_stp off
   bridge_maxwait 5

wpa-bridge br0

I realize that piCore doesn't use this sort of interface, but I'm not sure what all is being executed from this configuration.  Is this all being handled with ifplugd?

Well this handles the start up of the bridge. and it seems to be working fine.

Added "nodhcp" to the command line, to keep eth0 from starting automatically.

Added the following to bootlocal
Code: [Select]
ifconfig eth0 up
ifconfig wlan0 up

brctl addbr br0
brctl addif br0 wlan0 eth0
brctl stp br0 off
ifconfig br0 up
sleep 5s        #Sleep to allow the kernel to setup the bridge
wpa_supplicant -Dwext -iwlan0 -bbr0 -c/etc/wpa_supplicant.conf &
sleep 5s        #Sleep to let the wifi authenticate
udhcpc -i br0

I need to look through the wifi.sh script to see what error traps are in there for wifi.


Oh and PS, the rtl8192cu driver still has the power save problem with the edimax wifi that I use.  But they did fix the driver so that adding
Code: [Select]
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0
to modprobe.conf disables power save.

net-bridging kernel modules added to armv6/armv7 repo.

The bridging kernel modules are not dependent on normal net filter modules.  They are only dependent on the IPV6 modules.

Can you update the dependencies.

Modules in net/bridge/netfilter depending on netfilter, current .dep is correct. It is another question what is the best location for them, maybe moving them from bridging to netfilter would be better.

net/bridge/netfilter files are in extension net-bridging-3.18.10-piCore+.tcz   yes, these are needed.

net/netfilter and net/ipv4/netfilter are in extension netfilter-3.18.10-piCore+.tcz    and the bridging modules are not dependent on these.   I have removed this extension from my system and verified.

Use modinfo on any module in net/bridge/netfilter and look for dependency line.

Then it must be that I'm only using bridge.ko, so the netfilter stuff is not needed.    I would imagine that if I loaded br_netfilter.ko, others would be needed.

Just leave as is then, thanks
