2005-10-18[PATCH] bonding: cleanup comment for mode 1 IGMP xmit hackJohn W. Linville
Expand comment explaining MAC address selection for replicated IGMP frames transmitted in bonding mode 1 (active-backup). Also, a small whitespace cleanup. Signed-off-by: John W. Linville <linville@tuxdriver.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-10-04[PATCH] bonding: replicate IGMP traffic in activebackup modeJohn W. Linville
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.

2005-10-03[PATCH] fix bonding crash, remove old ABI supportJay Vosburgh
David S. Miller <davem@davemloft.net> wrote: >I think removing support for older ifenslave binaries is >the least painful solution to this problem. This patch removes backwards compatibility for old ifenslave binaries (ifenslave prior to verison 1.0.0). I did not similarly modify ifenslave itself; with sysfs on the horizon, I don't see that as being worthwhile.

2005-10-03[IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnlHerbert Xu
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. This patch is based on suggestions and prior work by Suzanne Wood and Paul McKenney. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-21[PATCH] bonding: Fix link monitor capability check (was skge: set mac ↵nsxfreddy@gmail.com
address oops with bonding) Fix bond_enslave link monitoring warning to check use_carrier status and ethtool_ops in addition to do_ioctl. This version checks ethtool_ops as well as do_ioctl, and also uses the per-bond params.use_carrier instead of the global use_carrier. Signed-off-by: Jason R.

2005-09-18[BOND]: Fix bond_init() error path handling.Florin Malita
From: Florin Malita <fmalita@gmail.com> bond_init() is not releasing rtnl_sem after register_netdevice() and before calling unregister_netdevice() (from bond_free_all()) in the exception path. 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).

2005-09-16[PATCH] bonding: plug reference count leakJay Vosburgh
Bonding leaks route structures when the ARP monitor is configured to send probes over VLANs. Originally reported by Ian Abel <ian.abel@mxtelecom.com>; his original fix was modified by Jay Vosburgh to correct coding style and to close a leak it missed.

2005-08-29[NET]: Kill skb->real_devDavid S. Miller
Bonding just wants the device before the skb_bond() decapsulation occurs, so simply pass that original device into packet_type->func() as an argument. It remains to be seen whether we can use this same exact thing to get rid of skb->input_dev as well. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-23[PATCH] bonding: inherit zero-copy flags of slavesArthur Kepner
This change allows a bonding device to inherit the "zero-copy" features of its slave devices. It was inspired by a couple of previous postings on this topic: http://marc.theaimsgroup.com/?l=bonding-devel&m=111924607327794&w=2 http://marc.theaimsgroup.com/?l=bonding-devel&m=111925242706297&w=2 and it's largely a combination of the patches that appear in those emails.

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!
