* | [PATCH] bonding: suppress duplicate packetsJay Vosburgh2006-03-043-26/+56
|/ | | | | | | | | | | | | | | | | | Originally submitted by Kenzo Iwami; his original description is: The current bonding driver receives duplicate packets when broadcast/ multicast packets are sent by other devices or packets are flooded by the switch. In this patch, new flags are added in priv_flags of net_device structure to let the bonding driver discard duplicate packets in dev.c:skb_bond(). Modified by Jay Vosburgh to change a define name, update some comments, rearrange the new skb_bond() for clarity, clear all bonding priv_flags on slave release, and update the driver version.

* [PATCH] bonding: UPDATED hash-table corruption in bond_alb.cJay Vosburgh2006-01-122-4/+4
| | | | | | | | | | | | | | | | | | | I believe I see the race Michael refers to (tlb_choose_channel may set head, which tlb_init_slave clears), although I was not able to reproduce it. I have updated his patch for the current netdev-2.6.git tree and added a version update. His original comment follows: Our systems have been crashing during testing of PCI HotPlug support in the various networking components. We've faulted in the bonding driver due to a bug in bond_alb.c:tlb_clear_slave() In that routine, the last modification to the TLB hash table is made without protection of the lock, allowing a race that can lead tlb_choose_channel() to select an invalid table element. -J Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* | [PATCH] bonding: replicate IGMP traffic in activebackup modeJohn W. Linville2005-10-041-2/+51
|/ | | | | | | | | | | | | | | Replicate IGMP frames across all slaves in activebackup mode. This ensures fail-over is rapid for multicast traffic as well. Otherwise, multicast traffic will be lost until the next IGMP membership report poll timeout. This is conceptually similar to the treatment of IGMP traffic in bond_alb_xmit. In that case, IGMP traffic transmitted on any slave is re-routed to the active slave in order to ensure that multicast traffic continues to be directed to the active receiver. Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | The following patch renames __in_dev_get() to __in_dev_get_rtnl() and introduces __in_dev_get_rcu() to cover the second case. 1) RCU with refcnt should use in_dev_get(). 2) RCU without refcnt should use __in_dev_get_rcu(). 3) All others must hold RTNL and use __in_dev_get_rtnl(). There is one exception in net/ipv4/route.c which is in fact a pre-existing race condition. I've marked it as such so that we remember to fix it.

As the device registration is not completed (dev->reg_state == NETREG_REGISTERING), the call to unregister_netdevice() triggers BUG_ON(dev->reg_state != NETREG_REGISTERED).

* bonding: xor/802.3ad improved slave hashJay Vosburgh2005-06-263-13/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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!
