2011-03-16bonding: enable netpoll without checking link statusAndy Gospodarek
Only slaves that are up should transmit netpoll frames, so there is no need to check to see if a slave is up before enabling netpoll on it. This resolves a reported failure on active-backup bonds where a slave interface is down when netpoll was enabled.

2011-03-15xen network backend driverIan Campbell
netback is the host side counterpart to the frontend driver in drivers/net/xen-netfront.c. The PV protocol is also implemented by frontend drivers in other OSes too, such as the BSDs and even Windows. The patch is based on the driver from the xen.git pvops kernel tree but has been put through the checkpatch.pl wringer plus several manual cleanup passes and review iterations. The driver has been moved from drivers/xen/netback to drivers/net/xen-netback. One major change from xen.git is that the guest transmit path (i.e. what looks like receive to netback) has been significantly reworked to remove the dependency on the out of tree PageForeign page flag (a core kernel patch which enables a per page destructor callback on the final put_page). This page flag was used in order to implement a grant map based transmit path (where guest pages are mapped directly into SKB frags). Instead this version of netback uses grant copy operations into regular memory belonging to the backend domain. Reinstating the grant map functionality is something which I would like to revisit in the future. Note that this driver depends on 2e820f58f7ad "xen/irq: implement bind_interdomain_evtchn_to_irqhandler for backend drivers" which is in linux next via the "xen-two" tree and is intended for the 2.6.39 merge window: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/backends this branch has only that single commit since 2.6.38-rc2 and is safe for cross merging into the net branch.

2011-03-15bonding: Improve syslog message at device creation timePhil Oester
When the bonding module is loaded, it creates bond0 by default. Then, when attempting to create bond0, the following messages are printed to syslog: kernel: bonding: bond0 is being created... kernel: bonding: Bond creation failed. Which seems to indicate a problem, when in reality there is no problem. Since the actual error code is passed down from bond_create, make use of it to print a bit less ominous message: kernel: bonding: bond0 is being created... kernel: bond0 already exists.

2011-03-15bonding: Call netif_carrier_off after register_netdevicePhil Oester
Bringing up a bond interface with all network cables disconnected does not properly set the interface as DOWN because the call to netif_carrier_off occurs too early in bond_init. The call needs to occur after register_netdevice has set dev->reg_state to NETREG_REGISTERED, so that netif_carrier_off will trigger the call to linkwatch_fire_event.

2011-03-15bonding: Incorrect TX queue offsetPhil Oester
When packets come in from a device with >= 16 receive queues headed out a bonding interface, syslog gets filled with this: kernel: bond0 selects TX queue 16, but real number of TX queues is 16 because queue_mapping is offset by 1. Adjust return value to account for the offset. This is a revision of my earlier patch (which did not use the skb_rx_queue_* helpers - thanks to Ben for the suggestion). Andy submitted a similar patch which emits a pr_warning on invalid queue selection, but I believe the log spew is not useful. We can revisit that question in the future, but in the interim I believe fixing the core problem is worthwhile.

2011-03-15RDMA/cma: Replace global lock in rdma_destroy_id() with id-specific oneSean Hefty
rdma_destroy_id currently uses the global rdma cm 'lock' to test if an rdma_cm_id has been bound to a device. This prevents an active address resolution callback handler from assigning a device to the rdma_cm_id after rdma_destroy_id checks for one. Instead, we can replace the use of the global lock around the check to the rdma_cm_id device pointer by setting the id state to destroying, then flushing all active callbacks. The latter is accomplished by acquiring and releasing the handler_mutex. Any active handler will complete first, and any newly scheduled handlers will find the rdma_cm_id in an invalid state. In addition to optimizing the current locking scheme, the use of the rdma_cm_id mutex is a more intuitive synchronization mechanism than that of the global lock. These changes are based on feedback from Doug Ledford <dledford@redhat.com> while he was trying to debug a crash in the rdma cm destroy path.

2011-03-15IB/cm: Cancel pending LAP message when exiting IB_CM_ESTABLISH stateSean Hefty
This problem was reported by Moni Shoua <monis@mellanox.com> and Amir Vadai <amirv@mellanox.com>: When destroying a cm_id from a context of a work queue and if the lap_state of this cm_id is IB_CM_LAP_SENT, we need to release the reference of this id that was taken upon the send of the LAP message. Otherwise, if the expected APR message gets lost, it is only after a long time that the reference will be released, while during that the work handler thread is not available to process other things. It turns out that we need to cancel any pending LAP messages whenever we transition out of the IB_CM_ESTABLISH state. This occurs when disconnecting - either sending or receiving a DREQ. It can also happen in a corner case where we receive a REJ message after sending an RTU, followed by a LAP. Add checks and cancel any outstanding LAP messages in these three cases. Canceling the LAP when sending a DREQ fixes the destroy problem reported by Moni. When a cm_id is destroyed in the IB_CM_ESTABLISHED state, it sends a DREQ to the remote side to notify the peer that the connection is going away.

2011-03-15IB/cm: Bump reference count on cm_id before invoking callbackSean Hefty
When processing a SIDR REQ, the ib_cm allocates a new cm_id. The refcount of the cm_id is initialized to 1. However, cm_process_work will decrement the refcount after invoking all callbacks. The result is that the cm_id will end up with refcount set to 0 by the end of the sidr req handler. If a user tries to destroy the cm_id, the destruction will proceed, under the incorrect assumption that no other threads are referencing the cm_id. This can lead to a crash when the cm callback thread tries to access the cm_id. This problem was noticed as part of a larger investigation with kernel crashes in the rdma_cm when running on a real time OS.

2011-03-15RDMA/cma: Fix crash in request handlersSean Hefty
Doug Ledford and Red Hat reported a crash when running the rdma_cm on a real-time OS. The crash has the following call trace: cm_process_work cma_req_handler cma_disable_callback rdma_create_id kzalloc init_completion cma_get_net_info cma_save_net_info cma_any_addr cma_zero_addr rdma_translate_ip rdma_copy_addr cma_acquire_dev rdma_addr_get_sgid ib_find_cached_gid cma_attach_to_dev ucma_event_handler kzalloc ib_copy_ah_attr_to_user cma_comp [ preempted ] cma_write copy_from_user ucma_destroy_id copy_from_user _ucma_find_context ucma_put_ctx ucma_free_ctx rdma_destroy_id cma_exch cma_cancel_operation rdma_node_get_transport rt_mutex_slowunlock bad_area_nosemaphore oops_enter They were able to reproduce the crash multiple times with the following details: Crash seems to always happen on the: mutex_unlock(&conn_id->handler_mutex); as conn_id looks to have been freed during this code path. An examination of the code shows that a race exists in the request handlers. When a new connection request is received, the rdma_cm allocates a new connection identifier. This identifier has a single reference count on it. If a user calls rdma_destroy_id() from another thread after receiving a callback, rdma_destroy_id will proceed to destroy the id and free the associated memory. However, the request handlers may still be in the process of running. When control returns to the request handlers, they can attempt to access the newly created identifiers. Fix this by holding a reference on the newly created rdma_cm_id until the request handler is through accessing it.
