2016-12-14IB/rdmavt: Only put mmap_info ref if it existsJim Foraker1-1/+2
rvt_create_qp() creates qp->ip only when a qp creation request comes from userspace (udata is not NULL). If we exceed the number of available queue pairs however, the error path always attempts to put a kref to this structure. If the requestor is inside the kernel, this leads to a crash. We fix this by checking that qp->ip is not NULL before caling kref_put().

2016-08-22IB/rdmvat: Fix double vfree() in rvt_create_qp() error pathMike Marciniszyn1-1/+2
The unwind logic for creating a user QP has a double vfree of the non-shared receive queue when handling a "too many qps" failure. The code unwinds the mmmap info by decrementing a reference count which will call rvt_release_mmap_info() which in turn does the vfree() of the r_rq.wq. The unwind code then does the same free. Fix by guarding the vfree() with the same test that is done in close and only do the vfree() if qp->ip is NULL.

2016-08-02IB/rdmavt, hfi1: Fix NFSoRDMA failure with FRMR enabledJianxin Xiong1-16/+32
Hanging has been observed while writing a file over NFSoRDMA. Dmesg on the server contains messages like these: [ 931.992501] svcrdma: Error -22 posting RDMA_READ [ 952.076879] svcrdma: Error -22 posting RDMA_READ [ 982.154127] svcrdma: Error -22 posting RDMA_READ [ 1012.235884] svcrdma: Error -22 posting RDMA_READ [ 1042.319194] svcrdma: Error -22 posting RDMA_READ Here is why: With the base memory management extension enabled, FRMR is used instead of FMR. The xprtrdma server issues each RDMA read request as the following bundle: (1)IB_WR_REG_MR, signaled; (2)IB_WR_RDMA_READ, signaled; (3)IB_WR_LOCAL_INV, signaled & fencing. These requests are signaled. In order to generate completion, the fast register work request is processed by the hfi1 send engine after being posted to the work queue, and the corresponding lkey is not valid until the request is processed. However, the rdmavt driver validates lkey when the RDMA read request is posted and thus it fails immediately with error -EINVAL (-22). This patch changes the work flow of local operations (fast register and local invalidate) so that fast register work requests are always processed immediately to ensure that the corresponding lkey is valid when subsequent work requests are posted. Local invalidate requests are processed immediately if fencing is not required and no previous local invalidate request is pending. To allow completion generation for signaled local operations that have been processed before posting to the work queue, an internal send flag RVT_SEND_COMPLETION_ONLY is added. The hfi1 send engine checks this flag and only generates completion for such requests.

2016-08-02IB/hfi1: Add the capability for reserved operationsMike Marciniszyn1-23/+62
This fix allows for support of in-kernel reserved operations without impacting the ULP user. The low level driver can register a non-zero value which will be transparently added to the send queue size and hidden from the ULP in every respect. ULP post sends will never see a full queue due to a reserved post send and reserved operations will never exceed that registered value. The s_avail will continue to track the ULP swqe availability and the difference between the reserved value and the reserved in use will track reserved availabity.

2016-08-02IB/rdmavt: Handle local operations in post sendJianxin Xiong1-5/+40
Some work requests are local operations, such as IB_WR_REG_MR and IB_WR_LOCAL_INV. They differ from non-local operations in that: (1) Local operations can be processed immediately without being posted to the send queue if neither fencing nor completion generation is needed. However, to ensure correct ordering, once a local operation is posted to the work queue due to fencing or completion requiement, all subsequent local operations must also be posted to the work queue until all the local operations on the work queue have completed. (2) Local operations don't send packets over the wire and thus don't need (and shouldn't update) the packet sequence numbers. Define a new a flag bit for the post send table to identify local operations. Add a new field to the QP structure to track the number of local operations on the send queue to determine if direct processing of new local operations should be enabled/disabled.
