2009-05-17bonding: fix link down handling in 802.3ad modeStephen Hemminger
One of the purposes of bonding is to allow for redundant links, and failover correctly if the cable is pulled. If all the members of a bonded device have no carrier present, the bonded device itself needs to report no carrier present to user space so management tools (like routing daemons) can respond. Bonding in 802.3ad mode does not work correctly for this because it incorrectly chooses a link that is down as a possible aggregator.

2008-12-26802.3ad: use standard ethhdr instead of ad_headerHolger Eitzenberger
802.3ad has its own ethhdr-like structure in the form of an ad_header, which is at the start of both the LACPDU and marker PDU. Both are the same from the struct values, both are packed as well. It's therefore perfectly fine to replace the ad_header by the ethhdr and to remove its definition. Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org> Signed-off-by: David S.

2008-11-12netdevice: safe convert to netdev_priv() #part-1Wang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

2008-11-06bonding: alternate agg selection policies for 802.3adJay Vosburgh
This patch implements alternative aggregator selection policies for 802.3ad. The existing policy, now termed "stable," selects the active aggregator by greatest bandwidth, and only reselects a new aggregator if the active aggregator is entirely disabled (no more ports or all ports down). This patch adds two new policies: bandwidth and count, selecting the active aggregator by total bandwidth (like the stable policy) or by the number of ports in the aggregator, respectively. These two policies also differ from the stable policy in that they will reselect the active aggregator when availability-related changes occur in the bond (e.g., link state change). This permits "gang failover" within 802.3ad, allowing redundant aggregators along parallel paths to always maintain the "best" aggregator as the active aggregator (rather than having to wait for the active to entirely fail). This patch also updates the driver version to 3.5.0. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-08-07bonding: refactor mii monitorJay Vosburgh
Refactor mii monitor. As with the previous ARP monitor refactor, the motivation for this is to handle locking rationally (in this case, removing conditional locking) and generally clean up the code. This patch breaks up the monolithic mii monitor into two phases: an inspection phase, followed by an optional commit phase. The commit phase is the only portion that requires RTNL or makes changes to state, and is only called when inspection finds something to change.

2008-03-25bonding: Fix locking in 802.3ad modeJay Vosburgh
The 802.3ad state machine lock can be acquired in both softirq and not softirq context, but was not held at _bh to prevent a deadlock (which could occur if a LACPDU arrived and was processed while the lock was held). Corrected this, now hold the state machine lock at _bh to prevent deadlock. Bug reported by Todd Fleisher <todd@fleish.org>.

Prior to use struct marker in the linux kernel markers, we need to clean two drivers which use this structure name.

2005-06-26bonding: xor/802.3ad improved slave hashJay Vosburgh
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>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
