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: NJay Vosburgh <fubar@us.ibm.com> Signed-off-by: NJeff Garzik <jgarzik@redhat.com>

The current ALB function that processes incoming ARPs does not handle traffic for VLANs configured above bonding. This causes traffic on those VLANs to all be assigned the same slave. This patch corrects that misbehavior by locating the bonding interface nested below the VLAN interface. Bug reported by Sven Anders <anders@anduras.de>, who also tested an earlier version of this patch and confirmed that it resolved the problem.

This patch adds better IPv6 failover support for bonding devices, especially when in active-backup mode and there are only IPv6 addresses configured, as reported by Alex Sidorenko. - Creates a new file, net/drivers/bonding/bond_ipv6.c, for the IPv6-specific routines. Both regular bonds and VLANs over bonds are supported. - Adds a new tunable, num_unsol_na, to limit the number of unsolicited IPv6 Neighbor Advertisements that are sent on a failover event. Default is 1. - Creates two new IPv6 neighbor discovery functions: ndisc_build_skb() ndisc_send_skb() These were required to support VLANs since we have to be able to add the VLAN id to the skb since ndisc_send_na() and friends shouldn't be asked to do this. These two routines are basically __ndisc_send() split into two pieces, in a slightly different order. - Updates Documentation/networking/bonding.txt and bumps the rev of bond support to 3.4.0. On failover, this new code will generate one packet: - An unsolicited IPv6 Neighbor Advertisement, which helps the switch learn that the address has moved to the new slave. Testing has shown that sending just the NA results in pretty good behavior when in active-back mode, I saw no lost ping packets for example.

I have been tracking for a while a case where when the network namespace exits the cleanup gets stck in an endless precessess of: unregister_netdevice: waiting for lo to become free. Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 It turns out that if you listen on a multicast address an unsubscribe packet is sent when the network device goes down. If you shutdown the network namespace without carefully cleaning up this can trigger the unsubscribe packet to be sent over the loopback interface while the network namespace is going down. All of which is fine except when we drop the packet and forget to free it leaking the skb and the dst entry attached to. As it turns out the dst entry hold a reference to the idev which holds the dev and keeps everything from being cleaned up. Yuck! By fixing my earlier thinko and add the needed kfree_skb and everything cleans up beautifully. Signed-off-by: NEric W. Biederman <ebiederm@xmission.com> Signed-off-by: NDavid S.

I was recently hunting a bug that occurred in network namespace cleanup. In looking at the code it became apparrent that we have and will continue to have cases where if we have anything going on in a network namespace there will be assumptions that the loopback device is present. Things like sending igmp unsubscribe messages when we bring down network devices invokes the routing code which assumes that at least the loopback driver is present. Therefore to avoid magic initcall ordering hackery that is hard to follow and hard to get right insert a call to register the loopback device directly from net_dev_init(). This guarantes that the loopback device is the first device registered and the last network device to go away. Signed-off-by: NEric W. Biederman <ebiederm@xmission.com> Signed-off-by: NDavid S.

When physical devices are inside of network namespace and that network namespace terminates we can not make them go away. We have to keep them and moving them to the initial network namespace is the best we can do. For virtual devices left in a network namespace that is exiting we have no need to preserve them and we now have the infrastructure that allows us to delete them. So delete virtual devices when we exit a network namespace. Keeping the necessary user space clean up after a network namespace exits much more tractable.

I noticed a contention on udp_memory_allocated on regular UDP applications. While tcp_memory_allocated is seldom used, it appears each incoming UDP frame is currently touching udp_memory_allocated when queued, and when received by application. One possible solution is to use sk_mem_reclaim_partial() instead of sk_mem_reclaim(), so that we keep a small reserve (less than one page) of memory for each UDP socket. We did something very similar on TCP side in commit 9993e7d3 ([TCP]: Do not purge sk_forward_alloc entirely in tcp_delack_timer()) A more complex solution would need to convert prot->memory_allocated to use a percpu_counter with batches of 64 or 128 pages.

This patch prepares for the new and extended feature-negotiation routines. The following feature-negotiation data structures are provided: * a container for the various (SP or NN) values, * symbolic state names to track feature states, * an entry struct which holds all current information together, * elementary functions to fill in and process these structures. Entry structs are arranged as FIFO for the following reason: RFC 4340 specifies that if multiple options of the same type are present, they are processed in the order of their appearance in the packet; which means that this order needs to be preserved in the local data structure (the later insertion code also respects this order). The struct list_head has been chosen for the following reasons: the most frequent operations are * add new entry at tail (when receiving Change or setting socket options); * delete entry (when Confirm has been received); * deep copy of entire list (cloning from listening socket onto request socket). The NN value has been set to 64 bit, which is a currently sufficient upper limit (Sequence Window feature has 48 bit). Thanks to Arnaldo, who contributed the streamlined layout of the entry struct.

The only user of the net_device->last_rx field is bonding. This patch adds a conditional update of last_rx to the bonding special logic in skb_bond_should_drop, causing last_rx to only be updated when the ARP monitor is running.

Commit 12dac075 ("tg3: adapt tg3 to use reworked PCI PM code") introduced the new PCI PM API to the tg3 driver. The patch was understandably conservative, so this patch elaborates on that work. The patch starts by creating a single point in tg3_set_power_state() to decide whether or not to enable WOL. The rest of the code in tg3_set_power_state() was then pivoted to use the result of this decision. The patch then makes sure the device is allowed to wakeup before reporting whether or not WOL is currently enabled. The final hunks of the patch consolidate where the WOL capability and WOL enabled flags are set to a single location.
