2007-10-21mlx4_core: Increase command timeout for INIT_HCA to 10 secondsJack Morgenstein
The current INIT_HCA firmware command timeout is sufficient for the default number of resources (QPs, CQs, etc) being allocated, but if the HCA profile is modified to increase the amount of resources, then a spurious timeout is detected and HCA initialization fails. Increase the timeout for the INIT_HCA command to 10 seconds, which also brings it into line with all the other command timeouts.

2007-10-19IPoIB/cm: Use common CQ for CM send completionsMichael S. Tsirkin
Use the same CQ for CM send completions as for all other IPoIB completions. This means all completions are processed via the same NAPI polling routine. This should help reduce the number of interrupts for bi-directional traffic (such as TCP) and fixes "driver is hogging interrupts" errors reported for IPoIB send side, e.g. <https://bugs.openfabrics.org/show_bug.cgi?id=508> To do this, keep a per-interface counter of outstanding send WRs, and stop the interface when this counter reaches the send queue size to avoid CQ overruns.

2007-10-19IB/uverbs: Fix checking of userspace object ownershipRoland Dreier
Commit 9ead190b ("IB/uverbs: Don't serialize with ib_uverbs_idr_mutex") rewrote how userspace objects are looked up in the uverbs module's idrs, and introduced a severe bug in the process: there is no checking that an operation is being performed by the right process any more. Fix this by adding the missing check of uobj->context in __idr_get_uobj(). Apparently everyone is being very careful to only touch their own objects, because this bug was introduced in June 2006 in 2.6.18, and has gone undetected until now.

2007-10-18IB/mlx4: Sanity check userspace send queue sizesJack Morgenstein
Add sanity checks to send queue sizes passed in from userspace. The minimum sq stride value below is taken from the MT25408 PRM (section 11.10, Table 306, log_sq_stride definition). Without this check, userspace can submit arbitrarily large/small values for the number of WQEs and the stride, which can crash the kernel.

2007-10-17IB/ehca: Change meaning of hca_cap_mr_pgsizeJoachim Fenkes
ehca_shca.hca_cap_mr_pgsize now contains all supported page sizes ORed together. This makes some checks easier to code and understand, plus we can return this value verbatim in query_hca(), fixing a problem with SRP (reported by Anton Blanchard -- thanks!).

2007-10-16RDMA/cma: Fix deadlock destroying listen requestsSean Hefty
Deadlock condition reported by Kanoj Sarcar <kanoj@netxen.com>. The deadlock occurs when a connection request arrives at the same time that a wildcard listen is being destroyed. A wildcard listen maintains per device listen requests for each RDMA device in the system. The per device listens are automatically added and removed when RDMA devices are inserted or removed from the system. When a wildcard listen is destroyed, rdma_destroy_id() acquires the rdma_cm's device mutex ('lock') to protect against hot-plug events adding or removing per device listens. It then tries to destroy the per device listens by calling ib_destroy_cm_id() or iw_destroy_cm_id(). It does this while holding the device mutex. However, if the underlying iw/ib CM reports a connection request while this is occurring, the rdma_cm callback function will try to acquire the same device mutex. Since we're in a callback, the ib_destroy_cm_id() or iw_destroy_cm_id() calls will block until their callback thread returns, but the callback is blocked waiting for the device mutex. Fix this by re-working how per device listens are destroyed. Use rdma_destroy_id(), which avoids the deadlock, in place of cma_destroy_listen(). Additional synchronization is added to handle device hot-plug events and ensure that the id is not destroyed twice.

2007-10-16RDMA/cma: Add locking around QP accessesSean Hefty
If a user allocates a QP on an rdma_cm_id, the rdma_cm will automatically transition the QP through its states (RTR, RTS, error, etc.) While the QP state transitions are occurring, the QP itself must remain valid. Provide locking around the QP pointer to prevent its destruction while accessing the pointer. This fixes an issue reported by Olaf Kirch from Oracle that resulted in a system crash: "An incoming connection arrives and we decide to tear down the nascent connection. The remote ends decides to do the same. We start to shut down the connection, and call rdma_destroy_qp on our cm_id. ... Now apparently a 'connect reject' message comes in from the other host, and cma_ib_handler() is called with an event of IB_CM_REJ_RECEIVED. It calls cma_modify_qp_err, which for some odd reason tries to modify the exact same QP we just destroyed."

2007-10-15IB/mthca: Avoid alignment traps when writing doorbellsRoland Dreier
Architectures such as ia64 see alignment traps when doing a 64-bit read from __be32 doorbell[2] arrays to do doorbell writes in mthca_write64(). Fix this by just passing the two halves of the doorbell value into mthca_write64(). This actually improves the generated code by allowing the compiler to see what's going on better.
