2013-02-21IB/core: Add "type 2" memory windows supportShani Michaeli
This patch enhances the IB core support for Memory Windows (MWs). MWs allow an application to have better/flexible control over remote access to memory. Two types of MWs are supported, with the second type having two flavors: Type 1 - associated with PD only Type 2A - associated with QPN only Type 2B - associated with PD and QPN Applications can allocate a MW once, and then repeatedly bind the MW to different ranges in MRs that are associated to the same PD. Type 1 windows are bound through a verb, while type 2 windows are bound by posting a work request. The 32-bit memory key is composed of a 24-bit index and an 8-bit key. The key is changed with each bind, thus allowing more control over the peer's use of the memory key. The changes introduced are the following: * add memory window type enum and a corresponding parameter to ib_alloc_mw. * type 2 memory window bind work request support. * create a struct that contains the common part of the bind verb struct ibv_mw_bind and the bind work request into a single struct. * add the ib_inc_rkey helper function to advance the tag part of an rkey. Consumer interface details: * new device capability flags IB_DEVICE_MEM_WINDOW_TYPE_2A and IB_DEVICE_MEM_WINDOW_TYPE_2B are added to indicate device support for these features. Devices can set either IB_DEVICE_MEM_WINDOW_TYPE_2A or IB_DEVICE_MEM_WINDOW_TYPE_2B if it supports type 2A or type 2B memory windows. It can set neither to indicate it doesn't support type 2 windows at all. * modify existing provides and consumers code to the new param of ib_alloc_mw and the ib_mw_bind_info structure Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Shani Michaeli <shanim@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

2013-02-15IB/mlx4: Fix bug unwinding on error in mlx4_ib_init_sriov()Dan Carpenter
We have to decrement "i" before calling mlx4_ib_free_demux_ctx() or we free something that wasn't allocated. That's fine for free_pv_object() but it would lead to a NULL dereference calling mlx4_ib_free_demux_ctx(). The null dereference is because ->tun is NULL when we check: if (!ctx->tun[i]) Also we didn't free ->sriov.demux[0] so it was a small leak.

2013-02-14IB/qib: Fix QP locate/remove raceMike Marciniszyn
remove_qp() can execute concurrently with a qib_lookup_qpn() on another CPU, which in of itself, is ok, given the RCU locking. The issue is that remove_qp() NULLs out the qp->next field so that a qib_lookup_qpn() might fail to find a qp if it occurs after the one that is being deleted. This is a momentary issue and subsequent qib_lookup_qpn() calls would find the qp's since the search restarts from the bucket head. At scale, the issue might causes dropped packets and unnecessary retransmissions. The fix just deletes the qp->next NULL assignment to prevent the remove_qp() from hiding qp's from qib_lookup_qpn().

2013-02-14RDMA/cxgb4: "cookie" can stay in host endiannessPaul Bolle
Work requests are passed between the host and the firmware with a "cookie". This cookie is swapped to big-endian when passed to the firmware and back to host endianness on return. This swapping seems to be implemented incorrectly. Moreover, the byte swapping triggers GCC warnings on 32 bit: drivers/infiniband/hw/cxgb4/cm.c: In function ‘passive_ofld_conn_reply’: drivers/infiniband/hw/cxgb4/cm.c:2803:12: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] drivers/infiniband/hw/cxgb4/cm.c: In function ‘send_fw_pass_open_req’: drivers/infiniband/hw/cxgb4/cm.c:2941:16: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] [...] But byte swapping isn't needed as the firmware doesn't actually touch the cookie.

2012-12-19RDMA/cxgb4: Fix bug for active and passive LE hash collision pathVipul Pandya
Retries active opens for INUSE errors. Logs any active ofld_connect_wr error replies. Sends ofld_connect_wr on same ctrlq. It needs to go on the same control txq as regular CPL active/passive messages. Retries on active open replies with EADDRINUSE. Uses active open fw wr only if active filter region is set. Adds stat for ofld_connect_wr failures. This patch also adds debugfs file to show endpoints. Signed-off-by: Vipul Pandya <vipul@chelsio.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-12-19RDMA/cxgb4: Fix LE hash collision bug for passive open connectionVipul Pandya
It establishes passive open connection through firmware work request. Passive open connection will go through this path as now instead of listening server we create a server filter which will redirect the incoming SYN packet to the offload queue. After this driver tries to establish the connection using firmware work request. Signed-off-by: Vipul Pandya <vipul@chelsio.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
