2014-09-01bonding: add slave_changelink support and use it for queue_idNikolay Aleksandrov
This patch adds support for slave_changelink to the bonding and uses it to give the ability to change the queue_id of the enslaved devices via netlink. It sets slave_maxtype and uses bond_changelink as a prototype for bond_slave_changelink. Example/test command after the iproute2 patch: ip link set eth0 type bond_slave queue_id 10 CC: David S.

2014-08-22bonding: Replace rcu_dereference() with rcu_access_pointer()Andreea-Cristina Bernat
This "rcu_dereference()" call is used directly in a condition. Since its return value is never dereferenced it is recommended to use "rcu_access_pointer()" instead of "rcu_dereference()". Therefore, this patch makes this replacement. The following Coccinelle semantic patch was used for solving it: @@ @@ ( if( (<+... - rcu_dereference + rcu_access_pointer (...) ...+>)) {...} | while( (<+... - rcu_dereference + rcu_access_pointer (...) ...+>)) {...} ) Signed-off-by: Andreea-Cristina Bernat <bernat.ada@gmail.com> Signed-off-by: David S.

Currently we're limited by a constant level of vlan nestings, and fail to find anything beyound that level (currently 2). To fix this - remove the limit of nestings when going through device tree, and when the end device is found - allocate the needed amount of vlan tags and return them, instead of found/not found.

2014-07-17bonding: destroy proc directory only after all bonds are goneVeaceslav Falico
Currently we might arrive to bond_net_exit() with some bonds left (that were created while the module is unloading). We take care of that by destroying sysfs (the last possibility to add new bonds) and then destroying all the remaining bonds. However, we destroy the /proc/net/bonding directory before destroying those last bonds, and get a warning that we're trying to destroy a non-empty proc directory (containing /proc/net/bonding/bondX). Fix this by moving bond_destroy_proc_dir() after all the bonds are destroyed, so that we're sure that no bonds exist.

Current L2 hash helper calculates destination eth addr and source ether addr as L2 hash factors. This patch is adding packet type ID field into L2 hash factors. While one of BOND_XMIT_POLICY_LAYER2 or BOND_XMIT_POLICY_{LAYER|ENCAP}23 is applied, for the 2nd level hash, enhanced hash method can help to distribute different types of packets like IPv4/IPv6 packets to different slave devices.

2014-07-16bonding: Do not try to send packets over dead link in TLB mode.Mahesh Bandewar
In TLB mode if tlb_dynamic_lb is NOT set, slaves from the bond group are selected based on the hash distribution. This does not exclude dead links which are part of the bond. Also if there is a temporary link event which brings down the interface, packets hashed on that interface would be dropped too. This patch fixes these issues and distributes flows across the UP links only. Also the array construction of links which are capable of sending packets happen in the control path leaving only link-selection during the data-path. One possible side effect of this is - at a link event; all flows will be shuffled to get good distribution. But impact of this should be minimum with the assumption that a member or members of the bond group are not available is a very temporary situation.

ALB learning packets are currentlyalways sent using the slave mac address for all vlans configured on top of bond. This is not always correct, as vlans may change their mac address. This patch introduced a concept of strict matching where the source of learning packets can either strictly match the address passed in, or it can determine a more correct address to use. There are 3 casese to consider: 1) Switchover. In this case, we have a new active slave and we need tell the switch about all addresses available on the slave. 2) Monitor. We'll periodically refresh learning info for all slaves. In this case, we refresh all addresses for current active, and just the slave address for other slaves. 3) Teaching of disabled adddress. This happens as part of the failover and in this case, we alwyas to use just the address provided.

2014-05-16bonding: Fix stacked device detection in arp monitoringVlad Yasevich
Prior to commit fbd929f2dce460456807a51e18d623db3db9f077 bonding: support QinQ for bond arp interval the arp monitoring code allowed for proper detection of devices stacked on top of vlans. Since the above commit, the code can still detect a device stacked on top of single vlan, but not a device stacked on top of Q-in-Q configuration. The search will only set the inner vlan tag if the route device is the vlan device. However, this is not always the case, as it is possible to extend the stacked configuration. With this patch it is possible to provision devices on top Q-in-Q vlan configuration that should be used as a source of ARP monitoring information. For example: ip link add link bond0 vlan10 type vlan proto 802.1q id 10 ip link add link vlan10 vlan100 type vlan proto 802.1q id 100 ip link add link vlan100 type macvlan Note: This patch limites the number of stacked VLANs to 2, just like before. The original, however had another issue in that if we had more then 2 levels of VLANs, we would end up generating incorrectly tagged traffic. This is no longer possible.
