* IB/cm: Use correct reject code for invalid GIDSean Hefty2006-09-22
| | | | | | | | | Set the reject code properly when rejecting a request that contains an invalid GID. A suitable GID is returned by the IB CM in the additional reject information (ARI). This is a spec compliancy issue. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/ipath: remove stale references to userspace SMABryan O'Sullivan2006-09-22
| | | | | | | | | When we first submitted a userspace subnet management agent, it was rejected, so we left it out of the final driver submission.

* IB/ipath: simplify layering codeBryan O'Sullivan2006-09-22
| | | | | | | | | A lot of ipath layer code was only called in one place.

| | | | | | | | | Change comment: no longer imply that user can set ipath_kpiobufs to zero. Actually set ipath_kpiobufs from parameter.

* IB/ipath: More changes to support InfiniPath on PowerPC 970 systemsBryan O'Sullivan2006-09-22
| | | | | | | | | | | Ordering of writethrough store buffers needs to be forced, and we need to use ifdef to get writethrough behavior to InfiniPath buffers, because there is no generic way to specify that at this time (similar to code in char/drm/drm_vm.c and block/z2ram.c).

* IB/ipath: Performance improvements via mmap of queuesRalph Campbell2006-09-22
| | | | | | | | | | Improve performance of userspace post receive, post SRQ receive, and poll CQ operations for ipath by allowing userspace to directly mmap() receive queues and completion queues. This eliminates the copying between userspace and the kernel in the data path. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/uverbs: Pass userspace data to modify_srq and modify_qp methodsRalph Campbell2006-09-22
| | | | | | | | | | Pass a struct ib_udata to the low-level driver's ->modify_srq() and ->modify_qp() methods, so that it can get to the device-specific data passed in by the userspace driver. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/uverbs: Allow resize CQ operation to return driver-specific dataRalph Campbell2006-09-22
| | | | | | | | | | Add a ib_uverbs_resize_cq_resp.driver_data field so that low-level drivers can return data from a resize CQ operation to userspace. Have ib_uverbs_resize_cq() only copy the cqe field, to avoid having to bump the userspace ABI.

* IB/uverbs: Fix lockdep warning when QP is created with 2 CQsRoland Dreier2006-09-22
| | | | | | | | | | | | Lockdep warns when userspace creates a QP that uses different CQs for send completions and receive completions, because both CQs are locked and their mutexes belong to the same lock class. However, we know that the mutexes are distinct and the nesting is safe (there is no possibility of AB-BA deadlock because the mutexes are locked with down_read()), so annotate the situation with SINGLE_DEPTH_NESTING to get rid of the lockdep warning. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/uverbs: Use idr_read_cq() where appropriateRoland Dreier2006-09-22
| | | | | | | There were two functions that open-coded idr_read_cq() in terms of idr_read_uobj() rather than using the helper. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipoib: Fix flush/start xmit race (from code review)Michael S. Tsirkin2006-09-22
| | | | | | | | | | Prevent flush task from freeing the ipoib_neigh pointer, while ipoib_start_xmit() is accessing the ipoib_neigh through the pointer it has loaded from the skb's hardware address.

* IB/mthca: Don't use privileged UAR for kernel accessMichael S. Tsirkin2006-09-22
| | | | | | | | Make kernel use UAR2 instead of UAR1 for hardware access: this adds sanity checking from the hardware side, without any performance cost. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/mthca: Fix lid used for sending trapsJack Morgenstein2006-09-22
| | | | | | | | | | | | | | | The SM LID used to send traps to is incorrectly set to port LID. This is a regression from 2.6.17 -- after a PortInfo MAD is received, no traps are sent to the SM LID. The traps go to the loopback interface instead, and are dropped there. The SM LID should be taken from the sm_lid of the PortInfo response.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The truncate code was never supposed to BUG() on an allocator it doesn't know about, but rather to ignore it. Right now, this does nothing, but when we change our allocation paths to use all suballocator files, this will allow current versions of the fs module to work fine.
