2011-07-18RDMA: Allow for NULL .modify_device() and .modify_port() methodsBart Van Assche4-36/+0
These methods don't make sense for iWARP devices, so rather than forcing them to implement stubs, just return -ENOSYS in the core if the hardware driver doesn't set .modify_device and/or .modify_port. Signed-off-by: Roland Dreier <roland@purestorage.com>

2011-06-17IB/qib: Ensure that LOS and DFE are being turned offMitko Haralanov2-8/+23
Due to timing, it is possible for the LOS and DFE to remain on. This is due to the link progressing to LinkUP prior to the driver getting the first Status Changed interrupt. By expanding the conditions under which LOS is turned off and DFE timeout is being set, timing is no longer an issue.

2011-06-17RDMA/cxgb4: Couple of abort fixesSteve Wise2-13/+38
- fix a race where the driver could end up sending a close_con_req after an abort_rpl. In c4iw_ep_disconnect(), send abort or close request with the ep mutex held. - fix a hang where driver fails to wake up when a connection is reset during a normal close. Wake up any waiters in the interrupt path, and correctly cleanup after rdma_fini() failures.

Memory allocated for user CQs gets rounded up to the next page boundary. And after rounding, we recalculate the resulting IQ depth and we need to make sure we don't exceed the HW limits. This bug can result a much smaller CQ allocated than was expected if the HW size field is exceeded, resulting in CQ overflow failures.

2011-05-24RDMA/cxgb4: Use completion objects for event blockingSteve Wise1-13/+5
There exists a race condition when using wait_queue_head_t objects that are declared on the stack. This was being done in a few places where we are sending work requests to the FW and awaiting replies, but we don't have an endpoint structure with an embedded c4iw_wr_wait struct. So the code was allocating it locally on the stack. Bad design. The race is: 1) thread on cpuX declares the wait_queue_head_t on the stack, then posts a firmware WR with that wait object ptr as the cookie to be returned in the WR reply. This thread will proceed to block in wait_event_timeout() but before it does: 2) An interrupt runs on cpuY with the WR reply. fw6_msg() handles this and calls c4iw_wake_up(). c4iw_wake_up() sets the condition variable in the c4iw_wr_wait object to TRUE and will call wake_up(), but before it calls wake_up(): 3) The thread on cpuX calls c4iw_wait_for_reply(), which calls wait_event_timeout(). The wait_event_timeout() macro checks the condition variable and returns immediately since it is TRUE. So this thread never blocks/sleeps. The function then returns effectively deallocating the c4iw_wr_wait object that was on the stack. 4) So at this point cpuY has a pointer to the c4iw_wr_wait object that is no longer valid. Further its pointing to a stack frame that might now be in use by some other context/thread. So cpuY continues execution and calls wake_up() on a ptr to a wait object that as been effectively deallocated. This race, when it hits, can cause a crash in wake_up(), which I've seen under heavy stress. It can also corrupt the referenced stack which can cause any number of failures. The fix: Use struct completion, which supports on-stack declarations. Completions use a spinlock around setting the condition to true and the wake up so that steps 2 and 4 above are atomic and step 3 can never happen in-between.

2011-05-09RDMA/iwcm: Get rid of enum iw_cm_event_statusRoland Dreier2-9/+9
The IW_CM_EVENT_STATUS_xxx values were used in only a couple of places; cma.c uses -Exxx values instead, and so do the amso1100, cxgb3 and cxgb4 drivers -- only nes was using the enum values (with the mild consequence that all nes connection failures were treated as generic errors rather than reported as timeouts or rejections). We can fix this confusion by getting rid of enum iw_cm_event_status and using a plain int for struct iw_cm_event.status, and converting nes to use -Exxx as the other iWARP drivers do. This also gets rid of the warning drivers/infiniband/core/cma.c: In function 'cma_iw_handler': drivers/infiniband/core/cma.c:1333:3: warning: case value '4294967185' not in enumerated type 'enum iw_cm_event_status' drivers/infiniband/core/cma.c:1336:3: warning: case value '4294967186' not in enumerated type 'enum iw_cm_event_status' drivers/infiniband/core/cma.c:1332:3: warning: case value '4294967192' not in enumerated type 'enum iw_cm_event_status' Signed-off-by: Roland Dreier <roland@purestorage.com> Reviewed-by: Steve Wise <swise@opengridcomputing.com> Reviewed-by: Sean Hefty <sean.hefty@intel.com> Reviewed-by: Faisal Latif <faisal.latif@intel.com>

2011-05-09RDMA/cxgb4: EEH errors can hang the driverSteve Wise3-53/+66
A few more EEH fixes: c4iw_wait_for_reply(): detect fatal EEH condition on timeout and return an error. The iw_cxgb4 driver was only calling ib_deregister_device() on an EEH event followed by a ib_register_device() when the device was reinitialized. However, the RDMA core doesn't allow multiple iterations of register/deregister by the provider. See drivers/infiniband/core/sysfs.c: ib_device_unregister_sysfs() where the kobject ref is held until the device is deallocated in ib_deallocate_device(). Calling deregister adds this kobj reference, and then a subsequent register call will generate a WARN_ON() from the kobject subsystem because the kobject is being initialized but is already initialized with the ref held. So the provider must deregister and dealloc when resetting for an EEH event, then alloc/register to re-initialize. To do this, we cannot use the device ptr as our ULD handle since it will change with each reallocation. This commit adds a ULD context struct which is used as the ULD handle, and then contains the device pointer and other state needed.

2011-05-09RDMA/cxgb4: Reset wait condition atomicallySteve Wise2-30/+26
The driver was never really waiting for RDMA_WR/FINI completions because the condition variable used to determine if the completion happened was never reset, and this condition variable is reused for both connection setup and teardown. This causes various driver crashes under heavy loads due to releasing resources too early. The fix is to use atomic bits to correctly reset the condition immediately after the completion is detected.

2011-03-22IB: Increase DMA max_segment_size on Mellanox hardwareDavid Dillow1-0/+3
By default, each device is assumed to be able only handle 64 KB chunks during DMA. By giving the segment size a larger value, the block layer will coalesce more S/G entries together for SRP, allowing larger requests with the same sg_tablesize setting. The block layer is the only direct user of it, though a few IOMMU drivers reference it as well for their *_map_sg coalescing code. pci-gart_64 on x86, and a smattering on on sparc, powerpc, and ia64. Since other IB protocols could potentially see larger segments with this, let's check those: - iSER is fine, because you limit your maximum request size to 512 KB, so we'll never overrun the page vector in struct iser_page_vec (128 entries currently). It is independent of the DMA segment size, and handles multi-page segments already. - IPoIB is fine, as it maps each page individually, and doesn't use ib_dma_map_sg(). - RDS appears to do the right thing and has no dependencies on DMA segment size, but I don't claim to have done a complete audit. - NFSoRDMA and 9p are OK -- they do not use ib_dma_map_sg(), so they doesn't care about the coalescing. - Lustre's ko2iblnd does not care about coalescing -- it properly walks the returned sg list. This patch ups the value on Mellanox hardware to 1 GB, which matches reported firmware limits on mlx4.
