[Development] Recent networking changes
by Michael Tremer 01 Jul '12

01 Jul '12

Good morning, I would like to update you about the recent changes on the networking code. I reckon nobody already noticed. Right at the beginning I would like to say, that I really need help to test my patches. I have done as much as I could possibly do, but this kind of code should be running very well and it's a pain in the ass when you have a box without any network connectivity. ---- * Support for DHCP, which has been requested several times at the summit, has been added and is currently working for me. I'll probably need more testers to verify the functionality, so please join. You'll need to checkout the network git and make sure you have installed the dhcp package from unstable: http://git.ipfire.org/?p=network.git;a=summary dhcp-4.2.2-3.ip3: https://pakfire.ipfire.org/build/df9a43e6-8d99-4ac7-973a-239a9120211b To enable the DHCP client on a zone type: network zone upl0 config create ipv4-dhcp ---- * Basic (!) firewalling support, which has no option to be configured, yet has been added. That means that I have been porting some of my old testing code I have written in 2009 to the network package. It can be enabled by running "firewall start" and disabled by typing "firewall stop". Don't expect to reach the internet anymore. The interesting part here is the structure of the chains. Have a look at "iptables -L -n -v". ---- * Hotplugging for USB devices. There has been some code, but due changes in udev and systemd it was not working anymore. This has been fixed and there has been support added for wireless devices. Example #1: If you now plug in a USB-LAN adapter, you will automatically create a port configuration for that device which is called p0, p1, ..., pN. If you unplug the adapter, the device will disappear automatically and will be removed from the zone where it has been in. If you plug it in again and there is a zone configuration for that port, the port will automatically added to the zone (if the zone is already running). Example #2: A wireless device is treated somewhat differently. When plugged in, there won't show up any interface (like wlan0). The reason for that is, that wireless devices can have multiple interfaces at the same time (think of multiple SSID access points). Those interfaces will be created when they are needed and automatically created when the USB device is plugged in. When you are building a wireless access point please make sure you have at least hostapd-0.7.3-2.ip3 and iw installed: https://pakfire.ipfire.org/build/08e1b509-2198-459f-9de2-2a9c8aa5a38e Please set up some testing hardware and check if this is working on your box as well. ---- * systemd is controlling the zones. Which enables us to them in parallel and access their status via dbus. ---- To not ask too much from you in a single email, I will stop here and we will see in about a week with what I am coming up then :D Again my request: Please test and file bug reports against: https://bugzilla.ipfire.org/enter_bug.cgi?product=IPFire&component=network Michael

[Development] Kernel 3.3
by Michael Tremer 17 May '12

17 May '12

Hey, I have been working on the update to Linux 3.3 in the last weeks. Unfortunately, I am running out if time in most things I do. So my request is, that some of you test the kernel that I already compiled. Scratch build: https://pakfire.ipfire.org/build/a740cfc3-1996-442b-87d7-a3432a6561f7 I don't expect anything weird, but I have not been able to test if it boots up at all. Make sure you check that the initrd has been generated after the installation, reboot and then run a couple of things. That's all. The reason for this kind of hurry is, that the release of Linux 3.4 is imminent (probably this week) and I don't like to get stuck on a too old kernel. Michael

Hello, On the Developer Summit we have spoken about network and systemd - how our implemention works and how we can improve it. I've written a roadmap which contains all changes and new features. http://wiki.ipfire.org/devel/network/systemd Please read through and perform any feedback or any new idea's you have. Thanks, Stefan
