2014-04-03RDMA/ocrdma: EQ full catastrophe avoidanceDevesh Sharma
Stale entries in the CQ being destroyed causes hardware to generate EQEs indefinitely for a given CQ. Thus causing uncontrolled execution of irq_handler. This patch fixes this using following sementics: * irq_handler will ring EQ doorbell atleast once and implement budgeting scheme. * cq_destroy will count number of valid entires during destroy and ring cq-db so that hardware does not generate uncontrolled EQE. * cq_destroy will synchronize with last running irq_handler instance. * arm_cq will always defer arming CQ till poll_cq, except for the first arm_cq call. * poll_cq will always ring cq-db with arm=SET if arm_cq was called prior to enter poll_cq. * poll_cq will always ring cq-db with arm=UNSET if arm_cq was not called prior to enter poll_cq.

On the other side, the default_dst protocol family is used to differentiate between IPv4 and IPv6 cases and, since, AF_UNSPEC != AF_INET, the processing takes the IPv6 path. Making the IPv4 assumption explicit by settting default_dst protocol family to AF_INET4 and preventing mixing of IPv4 and IPv6 addresses in snooped fdb entries fixes the corner case crashes.

2014-04-03rbd: prefix rbd writes with CEPH_OSD_OP_SETALLOCHINT osd opIlya Dryomov
In an effort to reduce fragmentation, prefix every rbd write with a CEPH_OSD_OP_SETALLOCHINT osd op with an expected_write_size value set to the object size (1 << order). Backwards compatibility is taken care of on the libceph/osd side. "The CEPH_OSD_OP_SETALLOCHINT hint is durable, in that it's enough to do it once. The reason every rbd write is prefixed is that rbd doesn't explicitly create objects and relies on writes creating them implicitly, so there is no place to stick a single hint op into. To get around that we decided to prefix every rbd write with a hint (just like write and setattr ops, hint op will create an object implicitly if it doesn't exist)."

2014-04-03rbd: num_ops parameter for rbd_osd_req_create()Ilya Dryomov
In preparation for prefixing rbd writes with an allocation hint introduce a num_ops parameter for rbd_osd_req_create(). The rationale is that not every write request is a write op that needs to be prefixed (e.g. watch op), so the num_ops logic needs to be in the callers.

2014-04-03libceph: bump CEPH_OSD_MAX_OP to 3Ilya Dryomov
Our longest osd request now contains 3 ops: copyup+hint+write. Also, CEPH_OSD_MAX_OP value in a BUG_ON in rbd_osd_req_callback() was hard-coded to 2. Fix it, and switch to rbd_assert while at it.

Doing rbd_obj_request_put() in rbd_img_request_fill() error paths is not only insufficient, but also triggers an rbd_assert() in rbd_obj_request_destroy(): Assertion failure in rbd_obj_request_destroy() at line 1867: rbd_assert(obj_request->img_request == NULL); rbd_img_obj_request_add() adds obj_requests to the img_request, the opposite is rbd_img_obj_request_del().
