* bonding: clean muticast addresses when device changes typeMoni Shoua2009-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bonding device forbids slave device of different types under the same master. However, it is possible for a bonding master to change type during its lifetime. This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND or the other way arround. The change of type requires device level multicast address cleanup because device level multicast addresses depend on the device type. The patch adds a call to dev_close() before the bonding master changes type and dev_open() just after that. In the example below I enslaved an IPoIB device (ib0) under bond0. Since each bonding master starts as device of type ARPHRD_ETHER by default, a change of type occurs when ib0 is enslaved. This is how /proc/net/dev_mcast looks like without the patch 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 01005e000116 5 bond0 1 0 01005e7ffffd 5 bond0 1 0 01005e000001 5 bond0 1 0 333300000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 333300000001 6 ib0 1 0 01005e000001 6 ib0 1 0 01005e7ffffd 6 ib0 1 0 01005e000116 6 ib0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff00000000000000000001 and this is how it looks like after the patch. 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 00ffffffff12601bffff00000000000000000001 5 bond0 1 0 00ffffffff12401bffff0000000000000ffffffd 5 bond0 1 0 00ffffffff12401bffff00000000000000000116 5 bond0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 00ffffffff12401bffff00000000000000000116 6 ib0 1 0 00ffffffff12401bffff0000000000000ffffffd 6 ib0 2 0 00ffffffff12401bffff00000000000000000001 6 ib0 2 0 00ffffffff12601bffff00000000000000000001 Signed-off-by: Moni Shoua <monis@voltaire.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

* net: release dst entry in dev_hard_start_xmit()Eric Dumazet2009-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One point of contention in high network loads is the dst_release() performed when a transmited skb is freed. This is because NIC tx completion calls dev_kree_skb() long after original call to dev_queue_xmit(skb). CPU cache is cold and the atomic op in dst_release() stalls. On SMP, this is quite visible if one CPU is 100% handling softirqs for a network device, since dst_clone() is done by other cpus, involving cache line ping pongs. It seems right place to release dst is in dev_hard_start_xmit(), for most devices but ones that are virtual, and some exceptions. David Miller suggested to define a new device flag, set in alloc_netdev_mq() (so that most devices set it at init time), and carefuly unset in devices which dont want a NULL skb->dst in their ndo_start_xmit(). List of devices that must clear this flag is : - loopback device, because it calls netif_rx() and quoting Patrick : "ip_route_input() doesn't accept loopback addresses, so loopback packets already need to have a dst_entry attached." - appletalk/ipddp.c : needs skb->dst in its xmit function - And all devices that call again dev_queue_xmit() from their xmit function (as some classifiers need skb->dst) : bonding, vlan, macvlan, eql, ifb, hdlc_fr Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

| * bonding: fix link down handling in 802.3ad modeStephen Hemminger2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | net: tx scalability works : trans_startEric Dumazet2009-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct net_device trans_start field is a hot spot on SMP and high performance devices, particularly multi queues ones, because every transmitter dirties it. Is main use is tx watchdog and bonding alive checks. But as most devices dont use NETIF_F_LLTX, we have to lock a netdev_queue before calling their ndo_start_xmit(). So it makes sense to move trans_start from net_device to netdev_queue. Its update will occur on a already present (and in exclusive state) cache line, for free. We can do this transition smoothly. An old driver continue to update dev->trans_start, while an updated one updates txq->trans_start. Further patches could also put tx_bytes/tx_packets counters in netdev_queue to avoid dirtying dev->stats (vlan device comes to mind) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* | bonding: ignore updelay param when there is no active slaveJiri Pirko2009-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pointed out by Sean E. Millichamp. Quote from Documentation/networking/bonding.txt: "Note that when a bonding interface has no active links, the driver will immediately reuse the first link that goes up, even if the updelay parameter has been specified (the updelay is ignored in this case). If there are slave interfaces waiting for the updelay timeout to expire, the interface that first went into that state will be immediately reused. This reduces down time of the network if the value of updelay has been overestimated, and since this occurs only in cases with no connectivity, there is no additional penalty for ignoring the updelay." This patch actually changes the behaviour in this way.

With this change we can now have all the loops that walk the array stop when they hit a zero since there will be no addresses after it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it.

* 802.3ad: use standard ethhdr instead of ad_headerHolger Eitzenberger2008-12-26
| | | | | | | | | | | | 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.
