2011-08-04IB/srp: Avoid duplicate devices from LUN scanBart Van Assche
commit fd1b6c4a693c9cac59375ffb36ffe5d7c079037c upstream. SCSI scanning of a channel:id:lun triplet in Linux works as follows (function scsi_scan_target() in drivers/scsi/scsi_scan.c): - If lun == SCAN_WILD_CARD, send a REPORT LUNS command to the target and process the result. - If lun != SCAN_WILD_CARD, send an INQUIRY command to the LUN corresponding to the specified channel:id:lun triplet to verify whether the LUN exists. So a SCSI driver must either take the channel and target id values in account in its quecommand() function or it should declare that it only supports one channel and one target id. Currently the ib_srp driver does neither. As a result scanning the SCSI bus via e.g. rescan-scsi-bus.sh causes many duplicate SCSI devices to be created. For each 0:0:L device, several duplicates are created with the same LUN number and with (C:I) != (0:0). Fix this by declaring that the ib_srp driver only supports one channel and one target id.

2011-05-25RDMA/cma: Add support for netlink statistics exportNir Muchtar
Add callbacks and data types for statistics export of all current devices/ids. The schema for RDMA CM is a series of netlink messages. Each one contains an rdma_cm_stat struct. Additionally, two netlink attributes are created for the addresses for each message (if applicable). Their types used are: RDMA_NL_RDMA_CM_ATTR_SRC_ADDR (The source address for this ID) RDMA_NL_RDMA_CM_ATTR_DST_ADDR (The destination address for this ID) sockaddr_* structs are encapsulated within these attributes. In other words, every transaction contains a series of messages like: -------message 1------- struct rdma_cm_id_stats { __u32 qp_num; __u32 bound_dev_if; __u32 port_space; __s32 pid; __u8 cm_state; __u8 node_type; __u8 port_num; __u8 reserved; } RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute - contains the source address RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute - contains the destination address -------end 1------- -------message 2------- struct rdma_cm_id_stats RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute -------end 2------- Signed-off-by: Nir Muchtar <nirm@voltaire.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2011-05-25RDMA/cma: Pass QP type into rdma_create_id()Sean Hefty
The RDMA CM currently infers the QP type from the port space selected by the user. In the future (eg with RDMA_PS_IB or XRC), there may not be a 1-1 correspondence between port space and QP type. For netlink export of RDMA CM state, we want to export the QP type to userspace, so it is cleaner to explicitly associate a QP type to an ID. Modify rdma_create_id() to allow the user to specify the QP type, and use it to make our selections of datagram versus connected mode.

2011-05-24RDMA/cxgb4: Use completion objects for event blockingSteve Wise
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 Dreier
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 Wise
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 Wise

2011-05-09RDMA/cma: Add an ID_REUSEADDR optionHefty, Sean
Lustre requires that clients bind to a privileged port number before connecting to a remote server. On larger clusters (typically more than about 1000 nodes), the number of privileged ports is exhausted, resulting in lustre being unusable. To handle this, we add support for reusable addresses to the rdma_cm. This mimics the behavior of the socket option SO_REUSEADDR. A user may set an rdma_cm_id to reuse an address before calling rdma_bind_addr() (explicitly or implicitly). If set, other rdma_cm_id's may be bound to the same address, provided that they all have reuse enabled, and there are no active listens. If rdma_listen() is called on an rdma_cm_id that has reuse enabled, it will only succeed if there are no other id's bound to that same address. The reuse option is exported to user space. The behavior of the kernel reuse implementation was verified against that given by sockets.

2011-04-27cxgb4: use pgprot_writecombine() on powerpcNishanth Aravamudan
Commit fe3cc0d99de6a9bf99b6c279a8afb5833888c1f7 ("powerpc: Add pgprot_writecombine") in benh's tree exposes the pgprot_writecombine() API to drivers on powerpc. cxgb4 has an open-coded version of the same, so use the common API now that it's available.
