2010-06-05bonding: allow user-controlled output slave selectionAndy Gospodarek1-0/+1
v2: changed bonding module version, modified to apply on top of changes from previous patch in series, and updated documentation to elaborate on multiqueue awareness that now exists in bonding driver. This patch give the user the ability to control the output slave for round-robin and active-backup bonding. Similar functionality was discussed in the past, but Jay Vosburgh indicated he would rather see a feature like this added to existing modes rather than creating a completely new mode. Jay's thoughts as well as Neil's input surrounding some of the issues with the first implementation pushed us toward a design that relied on the queue_mapping rather than skb marks. Round-robin and active-backup modes were chosen as the first users of this slave selection as they seemed like the most logical choices when considering a multi-switch environment. Round-robin mode works without any modification, but active-backup does require inclusion of the first patch in this series and setting the 'all_slaves_active' flag. This will allow reception of unicast traffic on any of the backup interfaces. This was tested with IPv4-based filters as well as VLAN-based filters with good results. More information as well as a configuration example is available in the patch to Documentation/networking/bonding.txt.

2007-12-07bonding: Add new layer2+3 hash for xor/802.3ad modesJay Vosburgh1-1/+2
Add new hash for balance-xor and 802.3ad modes. Originally submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by Jay Vosburgh to move setting of hash policy out of line, tweak the documentation update and add version update to 3.2.2. Glenn's original comment follows: Included is a patch for a new xmit_hash_policy for the bonding driver that selects slaves based on MAC and IP information. This is a middle ground between what currently exists in the layer2 only policy and the layer3+4 policy. This policy strives to be fully 802.3ad compliant by transmitting every packet of any particular flow over the same link. As documented the layer3+4 policy is not fully compliant for extreme cases such as ip fragmentation, so this policy is a nice compromise for environments that require full compliance but desire more than the layer2 only policy.

2005-06-27bonding: xor/802.3ad improved slave hashJay Vosburgh1-0/+7
Add support for alternate slave selection algorithms to bonding balance-xor and 802.3ad modes. Default mode (what we have now: xor of MAC addresses) is "layer2", new choice is "layer3+4", using IP and port information for hashing to select peer. Originally submitted by Jason Gabler for balance-xor mode; modified by Jay Vosburgh to additionally support 802.3ad mode. Jason's original comment is as follows: The attached patch to the Linux Etherchannel Bonding driver modifies the driver's "balance-xor" mode as follows: - alternate hashing policy support for mode 2 * Added kernel parameter "xmit_policy" to allow the specification of different hashing policies for mode 2. The original mode 2 policy is the default, now found in xmit_hash_policy_layer2(). * Added xmit_hash_policy_layer34() This patch was inspired by hashing policies implemented by Cisco, Foundry and IBM, which are explained in Foundry documentation found at: http://www.foundrynet.com/services/documentation/sribcg/Trunking.html#112750 Signed-off-by: Jason Gabler <jygabler@lbl.gov> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com>
2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+117
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
