I'm making a Debian package for it, and I have tried to find the "offical" distribution of this small program. I could not find an authorative source, instead a lot of copies and patched versions are scattered around the Internet (I maintain a patched version myself too). I would like to combine all the useful extra features and patches into this Debian package, so if you know of a patched version or maintain one yourself, please send it to me.

At http://pdsf.nersc.gov/linux/ifenslave.c is the last version I produced, that works with bonding in v2.2 and v2.4 kernels. Please note; I'm currently bound up in DOE/LBNL contract issues, that prevent any work on any GPL code on DOE/LBNL time. Folks, don't flame us - we know it, we are working on it. (The problem actually dates back to the 50's, when the labs where created!) Once this contract issue is cleared up, I've been given the 'Ok' to work on it again. Which means, since I don't have anything at home to work on bonding with, I can't officially support it.

The only bonding driver and ifenslave that worked for me was the patched version from http://sourceforge.net/projects/bonding . It runs fine over a quad starfire card, with vlans over it (ben's patch). You might consider packaging the ifenslave from that patch, and packaging the bonding driver as a kernel patch... -- Dani ...and Linux for all. ^ permalink raw reply [flat|nested] 4+ messages in thread

Notice I'm not on that page? I considered it a forked version. It also does things I talked to becker about, that is not nice to the system (MII polling as often it does is bad.) When I created the first 2.2 bonding patch, I didn't want to have to rewrite redhat's already in place ifenslave support (from the 2.0.xx kernel patch). The ifenslave listed on that page is broken in that regard. The original ifenslave bonded a device to a master that was already up and running; the master device was used also a xmit device (so it routed packets, and sometimes transmitted them). So, if the master device died, the slave(s) died with it. Not good. Redhat config files assumed the master was up and running, and you can add a slave to it without any problems. The slave device also picks up it's mac address from the master device. The version I created, the master device does nothing but route packets to slaves. This has a simple problem - no known mac hardware address. (ie, it's 0:0:0:0:0:0:0:0) That's bad. To set a hardware mac address, you need to down, change the hw mac, and re-up the device. But, redhat's scripts already assume the master is up and running, and downing the master to setup the mac hw means all IP routing information is lost. So I added the BOND_SETHWADDR, which allows ifenslave to add a mac address to the bond master without killing any IP routing information. But that's not totally correct either, since adding a mac hw address can screw up the arp tables (it appears not to, but that's just plain lucky). So, in summary, bonding is hack, I strongly dis-agree with what is at http://sourceforge.net/projects/bonding, but my hands are currently tied on doing much about it (I could, but I could suffer from consequences) -- ------------------------+-------------------------------------------------- Thomas Davis | ASG Cluster guy tadavis@lbl.gov | (510) 486-4524 | "80 nodes and chugging Captain!" ^ permalink raw reply [flat|nested] 4+ messages in thread
