* IB: Return qp pointer as part of ib_wcMichael S. Tsirkin2007-02-041-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | struct ib_wc currently only includes the local QP number: this matches the IB spec, but seems mostly useless. The following patch replaces this with the pointer to qp itself, and updates all low level drivers and all users. This has the following advantages: - Ability to get a per-qp context through wc->qp->qp_context - Existing drivers already have the qp pointer ready in poll cq, so this change actually saves a tiny bit (extra memory read) on data path (for ehca it would actually be expensive to find the QP pointer when polling a CQ, but ehca does not support SRQ so we can leave wc->qp as NULL for ehca) - Users that need the QP number can still get it through wc->qp->qp_num Use case: In IPoIB connected mode code, I have a common CQ shared by multiple QPs. To track connection usage, I need a way to get at some per-QP context upon the completion, and I would like to avoid allocating context object per work request just to stick a QP pointer into it. With this code, I can just use wc->qp->qp_context. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/mad: Fix race between cancel and receive completionRoland Dreier2006-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | When ib_cancel_mad() is called, it puts the canceled send on a list and schedules a "flushed" callback from process context. However, this leaves a window where a receive completion could be processed before the send is fully flushed. This is fine, except that ib_find_send_mad() will find the MAD and return it to the receive processing, which results in the sender getting both a successful receive and a "flushed" send completion for the same request. Understandably, this confuses the sender, which is expecting only one of these two callbacks, and leads to grief such as a use-after-free in IPoIB. Fix this by changing ib_find_send_mad() to return a send struct only if the status is still successful (and not "flushed"). The search of the send_list already had this check, so this patch just adds the same check to the search of the wait_list. Signed-off-by: Roland Dreier <rolandd@cisco.com>

A later call to list_del(&local->completion_list) would then corrupt the list. To fix this, remove the entry from local_list after looking it up but before releasing mad_agent_priv->lock, to prevent cancel_mads from finding and freeing it.

According to the spec, responses should match based on the combination of TID, management class, and requester LID/GID.

* IB/umad: Add support for large RMPP transfersJack Morgenstein2006-03-201-31/+135
| | | | | | | | | | | | | | | | | | | | | | | Add support for sending and receiving large RMPP transfers. The old code supports transfers only as large as a single contiguous kernel memory allocation. This patch uses linked list of memory buffers when sending and receiving data to avoid needing contiguous pages for larger transfers. Receive side: copy the arriving MADs in chunks instead of coalescing to one large buffer in kernel space. Send side: split a multipacket MAD buffer to a list of segments, (multipacket_list) and send these using a gather list of size 2. Also, save pointer to last sent segment, and retrieve requested segments by walking list starting at last sent segment. Finally, save pointer to last-acked segment. When retrying, retrieve segments for resending relative to this pointer. When updating last ack, start at this pointer.

* IB/mad: Simplify SMI by eliminating smi_check_local_dr_smp()Ralph Campbell2006-03-201-5/+3
| | | | | | | | | | | | | | | | The call to ib_get_agent_port() shouldn't be possible to fail when smi_check_local_dr_smp() is called from ib_mad_recv_done_handler(). When it is called from handle_outgoing_dr_smp(), the device and port_num come from mad_agent_priv so I assume the call to ib_get_agent_port() shouldn't fail either. In either case, smi_check_local_smp() only uses the mad_agent pointer to check that mad_agent->device->process_mad is not NULL. The device pointer would have to be the same as the one passed to smi_check_local_dr_smp() since that pointer is used later instead of the one checked in smi_check_local_smp().

* [IB] Fix MAD layer DMA mappings to avoid touching data buffer once mappedSean Hefty2005-10-251-163/+125
| | | | | | | | | | | | | | | | | The MAD layer was violating the DMA API by touching data buffers used for sends after the DMA mapping was done. This causes problems on non-cache-coherent architectures, because the device doing DMA won't see updates to the payload buffers that exist only in the CPU cache. Fix this by having all MAD consumers use ib_create_send_mad() to allocate their send buffers, and moving the DMA mapping into the MAD layer so it can be done just before calling send (and after any modifications of the send buffer by the MAD layer). Tested on a non-cache-coherent PowerPC 440SPe system. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [PATCH] IB: Keep MAD work completion validSean Hefty2005-04-161-1/+2
| | | | | | | | | | | Replace the *wc field in ib_mad_recv_wc from pointing to a structure on the stack to one allocated with the received MAD buffer. This allows a client to access the *wc field after their receive completion handler has returned.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
