2010-02-24IB/uverbs: use stack variable 'base' in ib_uverbs_add_oneAlexander Chiang
This change is not useful by itself, but sets us up for a future change that allows us to support more than IB_UVERBS_MAX_DEVICES in a system. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2010-02-24IB/uverbs: Use stack variable 'devnum' in ib_uverbs_add_oneAlexander Chiang

2010-02-24IB/uverbs: Remove dev_tableAlexander Chiang
dev_table's raison d'etre was to associate an inode back to a struct ib_uverbs_device. However, now that we've converted ib_uverbs_device to contain an embedded cdev (instead of a *cdev), we can use the container_of() macro and cast back to the containing device. There's no longer any need for dev_table, so get rid of it. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2010-02-24IB/uverbs: Convert *cdev to cdev in struct ib_uverbs_deviceAlexander Chiang
Instead of storing a pointer to a cdev, embed the entire struct cdev. This change allows us to use the container_of() macro in ib_uverbs_open() in a future patch. This change increases the size of struct ib_uverbs_device to 168 bytes across 3 cachelines from 80 bytes in 2 cachelines. However, we rearrange the members so that everything fits into the first cacheline except for the struct cdev. Finally, we don't touch the cdev in any fastpaths, so this change shouldn't negatively affect performance. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2010-02-24IB/iser: Remove redundant locking from iser scsi command response flowOr Gerlitz
Currently the iSER receive completion flow takes the session lock twice. Optimize it to avoid the first one by letting iser_task_rdma_finalize() be called only from the cleanup_task callback invoked by iscsi_free_task, thus reducing the contention on the session lock between the scsi command submission to the scsi command completion flows.

2010-02-24IB/iser: Use libiscsi passthrough modeOr Gerlitz
libiscsi passthrough mode invokes the transport xmit calls directly without first going through an internal queue, unlike the other mode, which uses a queue and a xmitworker thread. Now that the "cant_sleep" prerequisite of iscsi_host_alloc is met, move to use it. Handling xmit errors is now done by the passthrough flow of libiscsi. Since the queue/worker aren't used in this mode, the code that schedules the xmitworker is removed.

2010-02-24IB/iser: Remove unnecessary connection checksOr Gerlitz
Remove unnecessary checks for the IB connection state and for QP overflow, as conn state changes are reported by iSER to libiscsi and handled there. QP overflow is theoretically possible only when unsolicited data-outs are used; anyway it's being checked and handled by HW drivers.

2010-02-24IB/iser: New receive buffer posting logicOr Gerlitz
Currently, the recv buffer posting logic is based on the transactional nature of iSER which allows for posting a buffer before sending a PDU. Change this to post only when the number of outstanding recv buffers is below a water mark and in a batched manner, thus simplifying and optimizing the data path. Use a pre-allocated ring of recv buffers instead of allocating from kmem cache. A special treatment is given to the login response buffer whose size must be 8K unlike the size of buffers used for any other purpose which is 128 bytes.

2010-02-10RDMA/cm: Revert association of an RDMA device when binding to loopbackSean Hefty
Revert the following change from commit 6f8372b6 ("RDMA/cm: fix loopback address support") The defined behavior of rdma_bind_addr is to associate an RDMA device with an rdma_cm_id, as long as the user specified a non- zero address. (ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdma_bind_addr, no device is associated with the rdma_cm_id. Fix this. It turns out that important apps such as Open MPI depend on rdma_bind_addr() NOT associating any RDMA device when binding to a loopback address. Open MPI is being updated to deal with this, but at least until a new Open MPI release is available, maintain the previous behavior: allow rdma_bind_addr() to succeed, but do not bind to a device.

2009-12-22kfifo: move struct kfifo in placeStefani Seibold
This is a new generic kernel FIFO implementation. The current kernel fifo API is not very widely used, because it has to many constrains. Only 17 files in the current 2.6.31-rc5 used it. FIFO's are like list's a very basic thing and a kfifo API which handles the most use case would save a lot of development time and memory resources. I think this are the reasons why kfifo is not in use: - The API is to simple, important functions are missing - A fifo can be only allocated dynamically - There is a requirement of a spinlock whether you need it or not - There is no support for data records inside a fifo So I decided to extend the kfifo in a more generic way without blowing up the API to much. The new API has the following benefits: - Generic usage: For kernel internal use and/or device driver. - Provide an API for the most use case. - Slim API: The whole API provides 25 functions. - Linux style habit. - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros - Direct copy_to_user from the fifo and copy_from_user into the fifo. - The kfifo itself is an in place member of the using data structure, this save an indirection access and does not waste the kernel allocator. - Lockless access: if only one reader and one writer is active on the fifo, which is the common use case, no additional locking is necessary. - Remove spinlock - give the user the freedom of choice what kind of locking to use if one is required. - Ability to handle records. Three type of records are supported: - Variable length records between 0-255 bytes, with a record size field of 1 bytes. - Variable length records between 0-65535 bytes, with a record size field of 2 bytes. - Fixed size records, which no record size field. - Preserve memory resource. - Performance! - Easy to use! This patch: Since most users want to have the kfifo as part of another object, reorganize the code to allow including struct kfifo in another data structure. This requires changing the kfifo_alloc and kfifo_init prototypes so that we pass an existing kfifo pointer into them. This patch changes the implementation and all existing users.
