From bb6c96d72879fe1f674a804eb95b891def4ace61 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 24 Sep 2015 10:34:21 +0300 Subject: xprtrdma: Replace global lkey with lkey local to PD The core API has changed so that devices that do not have a global DMA lkey automatically create an mr, per-PD, and make that lkey available. The global DMA lkey interface is going away in favor of the per-PD DMA lkey. The per-PD DMA lkey is always available. Convert xprtrdma to use the device's per-PD DMA lkey for regbufs, no matter which memory registration scheme is in use.

ConnectIB has some known issues with memory registration using the local_dma_lkey (SEND, RDMA, RECV seems to work ok). Thus don't expose support for it (remove device->local_dma_lkey setting), and take advantage of the above commit such that no regression is introduced to working systems. The local_dma_lkey support will be restored in CX4 depending on FW capability query.

However, due to the difference in how multicast is handled on InfiniBand, we must join the appropriate multicast group before we can send to it. Previously we tried not to trigger the auto-create feature of the subnet manager when doing this because we didn't have tracking of these sendonly groups and the auto-creation might never get undone. The previous patch added timing to these sendonly joins and allows us to leave them after a reasonable idle expiration time. So supply all of the information needed to auto-create group.

Also correctly set a return value in error path. This caused a NULL pointer dereference in mlx5 which removed the support for LOCAL_DMA_LKEY.

Currently RoCE doesn't provide an API to find the netdev matching a given set of parameters, so this patch just disables the netdev enforcement for each incoming connections when the link layer is RoCE.

If we want to add proper XRC support it should be done with a new struct ib_xrc_wr. This shrinks the various WR structures by another 4 bytes.
