2011-03-22IB: Increase DMA max_segment_size on Mellanox hardwareDavid Dillow
By default, each device is assumed to be able only handle 64 KB chunks during DMA. By giving the segment size a larger value, the block layer will coalesce more S/G entries together for SRP, allowing larger requests with the same sg_tablesize setting. The block layer is the only direct user of it, though a few IOMMU drivers reference it as well for their *_map_sg coalescing code. pci-gart_64 on x86, and a smattering on on sparc, powerpc, and ia64. Since other IB protocols could potentially see larger segments with this, let's check those: - iSER is fine, because you limit your maximum request size to 512 KB, so we'll never overrun the page vector in struct iser_page_vec (128 entries currently). It is independent of the DMA segment size, and handles multi-page segments already. - IPoIB is fine, as it maps each page individually, and doesn't use ib_dma_map_sg(). - RDS appears to do the right thing and has no dependencies on DMA segment size, but I don't claim to have done a complete audit. - NFSoRDMA and 9p are OK -- they do not use ib_dma_map_sg(), so they doesn't care about the coalescing. - Lustre's ko2iblnd does not care about coalescing -- it properly walks the returned sg list. This patch ups the value on Mellanox hardware to 1 GB, which matches reported firmware limits on mlx4.

2011-03-15IB/srp: try to use larger FMR sizes to cover our mappingsDavid Dillow
Now that we can get larger SG lists, we can take advantage of HCAs that allow us to use larger FMR sizes. In many cases, we can use up to 512 entries, so start there and work our way down. Signed-off-by: David Dillow <dillowda@ornl.gov>
2011-03-15IB/srp: add support for indirect tables that don't fit in SRP_CMDDavid Dillow
This allows us to guarantee the ability to submit up to 8 MB requests based on the current value of SCSI_MAX_SG_CHAIN_SEGMENTS. While FMR will usually condense the requests into 8 SG entries, it is imperative that the target support external tables in case the FMR mapping fails or is not supported. We add a safety valve to allow targets without the needed support to reap the benefits of the large tables, but fail in a manner that lets the user know that the data didn't make it to the device. The user must add "allow_ext_sg=1" to the target parameters to indicate that the target has the needed support. If indirect_sg_entries is not specified in the modules options, then the sg_tablesize for the target will default to cmd_sg_entries unless overridden by the target options. Signed-off-by: David Dillow <dillowda@ornl.gov>
2011-03-15IB/srp: rework mapping engine to use multiple FMR entriesDavid Dillow
Instead of forcing all of the S/G entries to fit in one FMR, and falling back to indirect descriptors if that fails, allow the use of as many FMRs as needed to map the request. This lays the groundwork for allowing indirect descriptor tables that are larger than can fit in the command IU, but should marginally improve performance now by reducing the number of indirect descriptors needed. We increase the minimum page size for the FMR pool to 4K, as larger pages help increase the coverage of each FMR, and it is rare that the kernel would send down a request with scattered 512 byte fragments. This patch also move some of the target initialization code afte the parsing of options, to keep it together with the new code that needs to allocate memory based on the options given. Signed-off-by: David Dillow <dillowda@ornl.gov>
2011-03-15IB/srp: allow sg_tablesize to be set for each targetDavid Dillow
Different configurations of target software allow differing max sizes of the command IU. Allowing this to be changed per-target allows all targets on an initiator to get an optimal setting. We deprecate srp_sg_tablesize and replace it with cmd_sg_entries in preparation for allowing more indirect descriptors than can fit in the IU. Signed-off-by: David Dillow <dillowda@ornl.gov>

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.

2011-02-17IB/qib: Prevent double completions after a timeout or RNR errorMike Marciniszyn
There is a double completion associated with error handling for RC QPs. The sequence is: - The do_rc_ack() routine fields an RNR nack and there are 0 rnr_retries configured on the QP. - qib_error_qp() stops the pending timer - qib_rc_send_complete() is called from sdma_complete() - qib_rc_send_complete() starts the timer because the msb of the psn just completed says an ack is needed. - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP - rc_timeout() calls qib_restart_rc() - qib_restart_rc() calls qib_send_complete() with a IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the past The fix avoids starting the timer since another packet will never arrive.
