2011-01-10RDMA/cxgb4: Don't re-init wait object in init/fini pathsSteve Wise
Re-initializing the wait object in rdma_init()/rdma_fini() causes a timing window which can lead to a deadlock during close. Once this deadlock hits, all RDMA activity over the T4 device will be stuck. There's no need to re-init the wait object, so remove it.

2010-09-28RDMA/cxgb4: Use a mutex for QP and EP state transitionsSteve Wise
Move the connection setup/teardown paths to the workq thread removing spin lock/irq disable requirements for these paths. This allows calls down to the LLD for EP and QP state transition actions to be atomic with respect to processing CPL messages coming up from the HW. Namely, calls to rdma_init() and rdma_fini() can now be called with the mutex held avoiding many race conditions with the abort path. The QP spinlock is still used but only to manipulate the qp state. This allows the fastpaths, poll, post_send, and pos_recv, to run in the irq context.

2010-09-28RDMA/cxgb4: debugfs files for dumping active stagsSteve Wise

There exists a race condition where the app disconnects, which initiates an orderly close (via rdma_fini()), concurrently with an ingress abort condition, which initiates an abortive close operation. Since rdma_fini() must be called without IRQs disabled, the fini can be called after the QP has been transitioned to ERROR. This is ok, but we need to protect against qp->ep getting NULLed.
