      "message": "rds: fix rds_send_xmit() serialization\n\nrds_send_xmit() was changed to hold an interrupt masking spinlock instead of a\nmutex so that it could be called from the IB receive tasklet path.  This broke\nthe TCP transport because its xmit method can block and masks and unmasks\ninterrupts.\n\nThis patch serializes callers to rds_send_xmit() with a simple bit instead of\nthe current spinlock or previous mutex.  This enables rds_send_xmit() to be\ncalled from any context and to call functions which block.  Getting rid of the\nc_send_lock exposes the bare c_lock acquisitions which are changed to block\ninterrupts.\n\nA waitqueue is added so that rds_conn_shutdown() can wait for callers to leave\nrds_send_xmit() before tearing down partial send state.  This lets us get rid\nof c_senders.\n\nrds_send_xmit() is changed to check the conn state after acquiring the\nRDS_IN_XMIT bit to resolve races with the shutdown path.  Previously both\nworked with the conn state and then the lock in the same order, allowing them\nto race and execute the paths concurrently.\n\nrds_send_reset() isn\u0027t racing with rds_send_xmit() now that rds_conn_shutdown()\nproperly ensures that rds_send_xmit() can\u0027t start once the conn state has been\nchanged.  We can remove its previous use of the spinlock.\n\nFinally, c_send_generation is redundant.  Callers can race to test the c_flags\nbit by simply retrying instead of racing to test the c_send_generation atomic.\n\nSigned-off-by: Zach Brown \u003czach.brown@oracle.com\u003e\n"

      "message": "RDS/IB: add refcount tracking to struct rds_ib_device\n\nThe RDS IB client .remove callback used to free the rds_ibdev for the given\ndevice unconditionally.  This could race other users of the struct.  This patch\nadds refcounting so that we only free the rds_ibdev once all of its users are\ndone.\n\nMany rds_ibdev users are tied to connections.  We give the connection a\nreference and change these users to reference the device in the connection\ninstead of looking it up in the IB client data.  The only user of the IB client\ndata remaining is the first lookup of the device as connections are built up.\n\nIncrementing the reference count of a device found in the IB client data could\nrace with final freeing so we use an RCU grace period to make sure that freeing\nwon\u0027t happen until those lookups are done.\n\nMRs need the rds_ibdev to get at the pool that they\u0027re freed in to.  They exist\noutside a connection and many MRs can reference different devices from one\nsocket, so it was natural to have each MR hold a reference.  MR refs can be\ndropped from interrupt handlers and final device teardown can block so we push\nit off to a work struct.  Pool teardown had to be fixed to cancel its pending\nwork instead of deadlocking waiting for all queued work, including itself, to\nfinish.\n\nMRs get their reference from the global device list, which gets a reference.\nIt is left unprotected by locks and remains racy.  A simple global lock would\nbe a significant bottleneck.  More scalable (complicated) locking should be\ndone carefully in a later patch.\n\nSigned-off-by: Zach Brown \u003czach.brown@oracle.com\u003e\n"

This patch\nhandles any of these cases by keeping a pointer to the last\nop in the message in m_last_op.\n\nWhen the TX completion event fires, rds dispatches to per-op-type\ncleanup functions, and then does whole-message cleanup, if the\nlast op equalled m_last_op.\n\nThis patch also moves towards having op-specific functions take\nthe op struct, instead of the overall rm struct.\n\nrds_ib_connection has a pointer to keep track of a a partially-\ncompleted data send operation.

A theoretical\nsequence of events (from time t0 to t3) is thought to be as\nfollows,\n\nThread #1\nt0:\n    sock_release\n    rds_release\n    rds_send_drop_to /* wait on send completion */\nt2:\n    rds_rdma_drop_keys()   /* destroy \u0026 free all mrs */\n\nThread #2\nt1:\n    rds_ib_send_cq_comp_handler\n    rds_ib_send_unmap_rm\n    rds_message_unmapped   /* wake up #1 @ t0 */\nt3:\n    rds_message_put\n    rds_message_purge\n    rds_mr_put   /* memory corruption detected */\n\nThe problem with the rds_rdma_drop_keys() is it could\nremove a mr\u0027s refcount more than its due (i.e. repeatedly\nas long as it still remains in the tree (mr-\u003er_refcount \u003e 0)).\nTheoretically it should remove only one reference - reference\nby the tree.\n\n        /* Release any MRs associated with this socket */\n        while ((node \u003d rb_first(\u0026rs-\u003ers_rdma_keys))) {\n                mr \u003d container_of(node, struct rds_mr, r_rb_node);\n                if (mr-\u003er_trans \u003d\u003d rs-\u003ers_transport)\n                        mr-\u003er_invalidate \u003d 0;\n                rds_mr_put(mr);\n        }\n\nI think the correct way of doing it is to remove the mr from\nthe tree and rds_destroy_mr it first, then a rds_mr_put()\nto decrement its reference count by one.

But it turns\nout that we only ever use the first 32 characters so it\u0027s OK.
