2010-10-20net: avoid RCU for NOCACHE dstEric Dumazet
There is no point using RCU for dst we allocate for a very short time (used once). Change dst_release() to take DST_NOCACHE into account, but also change skb_dst_set_noref() to force a refcount increment for such dst. This is a _huge_ gain, because we dont waste memory to store xx thousand of dsts. Instead of queueing them to RCU, we can free them instantly. CPU caches can stay hot, re-using same memory blocks to hold temporary dsts. Note : remove unneeded smp_mb__before_atomic_dec(); in dst_release(), since atomic_dec_return() implies a full memory barrier. Stress test, 160.000.000 udp frames sent, IP route cache disabled (DDOS).

2010-10-20netpoll: Revert napi_poll fix for bonding driverNeil Horman
In an erlier patch I modified napi_poll so that devices with IFF_MASTER polled the per_cpu list instead of the device list for napi. I did this because the bonding driver has no napi instances to poll, it instead expects to check the slave devices napi instances, which napi_poll was unaware of. Looking at this more closely however, I now see this isn't strictly needed. As the bond driver poll_controller calls the slaves poll_controller via netpoll_poll_dev, which recursively calls poll_napi on each slave, allowing those napi instances to get serviced. The earlier patch isn't at all harmfull, its just not needed, so lets revert it to make the code cleaner.

It relies on some per cpu bits, but the shutdown path forces some rescheduling as we cancel workqueues for the driver and wait for some device refcounts. If after the forced reschedule, we wind up on a different cpu we trigger the bughalt in unblock_netpoll_tx. The fix is to remove the netpoll block/unblock calls from bond_release_all. This is safe to do because bond_uninit, which is called via ndo_uninit in rollback_registered_many, doesn't occur until we send a NETDEV_UNREGISTER event, which triggers netconsole to remove us as a netpoll client, so we are guaranteed not to recurse into our own tx path here.

2010-10-18bonding: Fix napi poll for bonding driverNeil Horman
Usually the netpoll path, when preforming a napi poll can get away with just polling all the napi instances of the configured device. Thats not the case for the bonding driver however, as the napi instances which may wind up getting flagged as needing polling after the poll_controller call don't belong to the bonded device, but rather to the slave devices. Fix this by checking the device in question for the IFF_MASTER flag, if set, we know we need to check the full poll list for this cpu, rather than just the devices napi instance list.

2010-10-18bonding: Fix deadlock in bonding driver resulting from internal locking when ↵Neil Horman
using netpoll The monitoring paths in the bonding driver take write locks that are shared by the tx path. If netconsole is in use, these paths can call printk which puts us in the netpoll tx path, which, if netconsole is attached to the bonding driver, result in deadlock (the xmit_lock guards are useless in netpoll_send_skb, as the monitor paths in the bonding driver don't claim the xmit_lock, nor should they). The solution is to use a per cpu flag internal to the driver to indicate when a cpu is holding the lock in a path that might recusrse into the tx path for the driver via netconsole. By checking this flag on transmit, we can defer the sending of the netconsole frames until a later time using the retransmit feature of netpoll_send_skb that is triggered on the return code NETDEV_TX_BUSY. I've tested this and am able to transmit via netconsole while causing failover conditions on the bond slave links. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

2010-10-18bonding: Fix bonding drivers improper modification of netpoll structureNeil Horman
The bonding driver currently modifies the netpoll structure in its xmit path while sending frames from netpoll. This is racy, as other cpus can access the netpoll structure in parallel. Since the bonding driver points np->dev to a slave device, other cpus can inadvertently attempt to send data directly to slave devices, leading to improper locking with the bonding master, lost frames, and deadlocks. This patch fixes that up. This patch also removes the real_dev pointer from the netpoll structure as that data is really only used by bonding in the poll_controller, and we can emulate its behavior by check each slave for IS_UP.

The 2006 patch changes the unlock to not re-enable IRQs, which eliminates the potential deadlock. But this bit was missed. We should change the lock function as well so it balances nicely.

2010-10-18tipc: Simplify bearer shutdown logicAllan Stephens
Optimize processing in TIPC's bearer shutdown code, including: 1. Remove an unnecessary check to see if TIPC bearer's can exist. 2. Don't release spinlocks before calling a media-specific disabling routine, since the routine can't sleep. 3. Make bearer_disable() operate directly on a struct bearer, instead of needlessly taking a name and then mapping that to the struct.
