    libibverbs: Add Cross-channel capability
    
    Added ibv_post_task.
    
    This code enables the hardware feature referred as Cross-channel. The
    functionality supports the posting of a task list to a Host Channel Adapter (HCA),
    with a single completion queue entry indicating when the task list has completed.
    The task list may have entries posted to multiple Queue Pairs (QPs) and includes
    send and receive communication primitives, as well as the communication
    coordination primitives wait, send_enable, and receive_enable. Since a single post
    of tasks to QPs initiates the communication pattern, and all progress is handled
    by the HCA.
    
    ibv_post_task - post a list of send/recv tasks (TAKSs) to QPs
    
    It is added using verbs extensions approach.
    

Igor Ivanov <Igor.Ivanov@itseez.com>	2013-03-14

    libibverbs: Added new flag IB_DEVICE_CROSS_CHANNEL into enum ib_device_cap_flags
    
    This flag demonstrates presence of Cross-channel capability in a device.
    
    The device can be programmed to execute IO operation flows that involve
    synchronization of IO operations on different IO channels as well as conditional
    execution based on arithmetic operations on memory-resident variables. This
    capability enables to program complex IO operation flows with a single function
    call, hereby significantly reducing overhead associated with IO processing.

    libibverbs: Add ibv_open_qp
    
    XRC receive QPs are shareable across multiple processes.  Allow
    any process with access to the xrc domain to open an existing
    QP.  After opening the QP, the process will receive events
    related to the QP and be able to modify the QP.
    

Yishai Hadas <yishaih@mellanox.com>	2013-05-12

    libibverbs: Add support for XRC QPs
    
    XRC queue pairs: xrc defines two new types of QPs.  The
    initiator, or send-side, xrc qp behaves similar to a send-
    only RC qp.  xrc send qp's are managed through the existing
    QP functions.  The send_wr structure is extended in a back-
    wards compatible way to support posting sends on a send xrc
    qp, which require specifying the remote xrc srq.
    
    The target, or receive-side, xrc qp behaves differently
    than other implemented qp's.  A recv xrc qp can be created,
    modified, and destroyed like other qp's through the existing
    calls.  The qp_init_attr structure is extended for xrc qp's.
    
    Because xrc recv qp's are bound to an xrcd, rather than a pd,
    it is intended to be used among multiple processes.  Any process
    with access to an xrcd may allocate and connect an xrc recv qp.
    The actual xrc recv qp is allocated and managed by the kernel.
    If the owning process explicit destroys the xrc recv qp, it is
    destroyed.  However, if the xrc recv qp is left open when the
    user process exits or closes its device, then the lifetime of
    the xrc recv qp is bound with the lifetime of the xrcd.
    

Yishai Hadas <yishaih@mellanox.com>	2013-05-12

    livibverbs: Add support for XRC SRQs
    
    XRC support requires the use of a new type of SRQ.
    XRC shared receive queues: xrc srq's are similar to normal
    srq's, except that they are bound to an xrcd, rather
    than to a protection domain.  Based on the current spec
    and implementation, they are only usable with xrc qps.  To
    support xrc srq's, we define a new srq_init_attr structure
    to include an srq type and other needed information.
    
    The kernel ABI is also updated to allow creating extended
    SRQs.
    

Yishai Hadas <yishaih@mellanox.com>	2013-05-07

    libibverbs: Introduce XRC domains
    
    XRC introduces several new concepts and structures, one of
    which is the XRC domain.
    
    XRC domains: xrcd's are a type of protection domain used to
    associate shared receive queues with xrc queue pairs.  Since
    xrcd are meant to be shared among multiple processes, we
    introduce new APIs to open/close xrcd's.
    
    The user to kernel ABI is extended to account for opening/
    closing the xrcd.

Hadar Hen Zion <hadarh@mellanox.com>	2013-02-11

    Implement ibv_create_flow and ibv_destroy_flow
    
    According to the new flow steering verbs API and using the extended verbs
    mechanism.
    ibv_create_flow verb allow user space applications to attach flow
    specifications for a QP. ibv_flow_attr is a pointer for flow specifications
    structs that contain mandatory control parameters and optional L2, L3 and L4
    headers.
    ibv_flow_attr struct is a mandatory control struct:
    
    struct ibv_flow_attr {
uint32_t comp_mask;           
enum ibv_flow_attr_type type;           
uint16_t size;           
uint16_t priority;           
uint8_t num_of_specs;           
uint8_t port;           
uint32_t flags;           
/* Following are the optional layers according to user request           
 * struct ibv_flow_spec_xxx           
 * struct ibv_flow_spec_yyy           
 */           
    };
    
    And can be followed by the optional flow headers structs:
    struct ibv_flow_spec_ib
    struct ibv_flow_spec_eth
    struct ibv_flow_spec_ipv4
    struct ibv_flow_spec_tcp_udp
    
    ib_flow_attr pointer includes ibv_flow_attr and headers structs, which can be
    detected by reading the size and num_of_specs fields in ib_flow_attr struct.
    
    The user can choose flow type according to the following enum:
    enum ibv_flow_attr_type {
/* steering according to rule specifications */           
IBV_FLOW_ATTR_NORMAL		= 0x0,           
/* default unicast and multicast rule -           
 * receive all Eth traffic which isn't steered to any QP           
 */           
IBV_FLOW_ATTR_ALL_DEFAULT	= 0x1,           
* default multicast rule -           
* receive all Eth multicast traffic which isn't steered to any QP           
*/           
IBV_FLOW_ATTR_MC_DEFAULT	= 0x2,           
/* sniffer rule - receive all port traffic */           
IBV_FLOW_ATTR_MIRROR		= 0x3,           
    };
    
    When setting flow type to NORMAL, the incoming traffic will be steer
    according to the rule specifications. ALL_DEFAULT and MC_DEFAULT rules options
    are valid only for Ethernet link type since IB link type packets always include
    QP number.
    
    To detach the flow from the QP, ibv_destroy_flow is called.
    ibv_destroy_flow requires struct ibv_flow which contains a uobject handle.
    

Hadar Hen Zion <hadarh@mellanox.com>	2013-03-05

    Add general definitions to support verbs extensions
    
    To support verbs extension mechanism between user space libraries and
    uverbs kernel module, each new added verb which is based on verbs extension
    approach should include the following:
    1. Enum index greater than IB_USER_VERBS_CMD_THRESHOLD.
    2. Additional common fields in the kernel-user struct:
__u16 provider_in_words;           
__u16 provider_out_words;           
__u32 cmd_hdr_reserved;           
__u32 comp_mask;           
    
       The above fields will be initialized by
       IBV_INIT_CMD_EX/IBV_INIT_CMD_RESP_EX new macros.
    
    Added uverbs_cmd_type to recognize if command should be processed as a legacy or as an extended.
    Added new header support macros.

    libibverbs: Infrastructure to support verbs extensions
    
    Based on a patch from Yishai Hadas <yishaih@mellanox.com>
    
    Infrastructure to support extended verbs capabilities in a forward/backward
    manner.
    
    Support for extensions is determined by the provider calling
    verbs_register_driver in place of ibv_register_driver.  When
    extensions are enabled, ibverbs sets the current alloc_context /
    free_context device operations to NULL.  These are used to
    indicate that the struct ibv_device may be cast to struct
    verbs_device.
    
    With extensions, ibverbs allocates the ibv_context structure
    and calls into the provider to initialize it.  The init call
    is part of the verbs_device struct.

    Update kernel API header to include link_layer
    
    Modify the code to handle returning the link layer of a port from the
    kernel to the library.  The kernel has done this since commit
    2420b60b1dc4 ("IB/uverbs: Return link layer type to userspace for
    query port operation"), merged in 2.6.37-rc1.
    
    The new field does not change the size of struct ibv_query_port_resp
    as it replaces a reserved field.  Binary compatibility between the
    kernel to the library is kept, since old kernels running below new
    library will not zero that field, so it will be read as "unspecified,"
    while an old library running over new kernel will ignore the value
    returned by the kernel.
    
    The solution was suggested by Roland Dreier <roland@purestorage.com>
    and Jason Gunthorpe <jgunthorpe@obsidianresearch.com>
    

Or Gerlitz <ogerlitz@mellanox.com>	2011-07-20

    Add link_layer field port attribute
    
    The new field has three possible values: IBV_LINK_LAYER_UNSPECIFIED,
    IBV_LINK_LAYER_INFINIBAND, IBV_LINK_LAYER_ETHERNET.  It can be used by
    applications to know the link layer used by the port, which can be
    either InfiniBand or Ethernet.
    
    The addition of the new field does not change the size of struct
    ibv_port_attr due to alignment of the preceding fields.  Binary
    compatibility between the library to applications is kept, since old
    apps running over new library do not read this field, and new apps
    running over old library will determine the link layer as unspecified
    and hence take their IB code path.

    Handle huge pages in ibv_fork_init() and madvise tracking
    
    When fork support is enabled in libibverbs, madvise() is called for
    every memory page that is registered as a memory region.  Memory
    ranges that are passed to madvise() must be page aligned and the size
    must be a multiple of the page size.
    
    libibverbs uses sysconf(_SC_PAGESIZE) to find out the system page size
    and rounds all ranges passed to reg_mr() according to this page size.
    When memory from libhugetlbfs is passed to reg_mr(), this does not
    work as the page size for this memory range might be different
    (e.g. 16MB).  So libibverbs would have to use the huge page size to
    calculate a page aligned range for madvise.
    
    As huge pages are provided to the application "under the hood" when
    preloading libhugetlbfs, the application does not have any knowledge
    about when it registers a huge page or a usual page.
    
    To work around this issue, detect the use of huge pages in libibverbs
    and align memory ranges passed to madvise according to the huge page
    size.  Determining the page size of a given memory range by watching
    madvise() fail has proven to be unreliable.  So we introduce the
    RDMAV_HUGEPAGES_SAFE environment variable to let the user decide if
    the page size should be checked on every reg_mr() call or not. This
    requires the user to be aware if huge pages are used by the running
    application or not.
    
    I did not add an aditional API call to enable this, as applications
    can use setenv() + ibv_fork_init() to enable checking for huge pages
    in the code.

    Fix crash if no devices and ibv_get_device_list() is called multiple times
    
    If no devices are found, ibverbs_init() sets num_devices to 0.  This
    means the next call to __ibv_get_device_list() would call
    ibverbs_init() again, which crashes because ibverbs_init() leaves
    various internal pointers pointing to freed memory.
    
    Fix this by using pthread_once() to call ibverbs_init() exactly once,
    and then doing the right thing even if num_devices stays 0.

    Undo changes in memory range tree when madvise() fails
    
    ibv_madvise_range() doesn't cleanup if madvise() fails.  This patch
    rolls back changes already made in the memory range tracking tree by
    madvise() calls before the one that failed.  We can do this fairly
    simply by simply restarting ibv_madvise_range() from the original
    start to the current location with the opposite advice/inc values.

    Fix incorrect splits/merges in the memory tree when madvise() fails.
    
    ibv_madvise_range() first manages (splits or merges) memory ranges in
    the tree and only then calls madvise().  If madvise() fails, the
    tree's memory range may contain incorrectly split or merged ranges.
    The patch undoes the split and merge operations performed on the node
    which caused the madvise() failure as well as on that node's
    neighbors.

    Do not use enum types for bit flags
    
    Arithmetic operations on enum members do not result in the enum type;
    C++ is stricter about this than C.  So using flag enums results in
    compile errors when they are OR'd together in a C++ application.
    
    To fix this, replace all flag enum objects with int.  int was selected
    to preserve the ABI; we checked that enum types are the same size as
    int on at least i386, x86-64, ppc32, ppc64, ia64, and mips, and arm
    and sparc also appear compatible with this choice.

    Always return valid bad_wr on error from ibv_post_{send,recv,srq_recv}
    
    There are error cases in the kernel's uverbs work request posting
    functions where the return value is negative (i.e., an error) and yet a
    non-zero resp.bad_wr is not written back to userspace.  In this case,
    ibv_cmd_post_send() should still set the bad_wr pointer.

    Fix too-big madvise() call in ibv_madvise_range()
    
    When the first memory range found in ibv_madvise_range() is merged
    with the previous range before entering the loop that calls madvise(),
    a too-big range could be passed to madvise().  This could lead to
    trying to madvise() memory that has already been freed and unmapped,
    which causes madvise() and therefore ibv_reg_mr() to fail.
    
    Fix this by making sure we don't madvise() any memory outside the
    range passed into ibv_madvise_range().

    This reverts commit 5eaee85aec025be16e5aeeaac64abc6d8d9c191c.
    
    This breaks ibv_destroy_ah() with libmthca, and isn't really appropriate
    for the stable branch.
    

Roland Dreier <rolandd@cisco.com>	2007-01-31

    Fix unset context breakage when a low-level driver does kernel bypass
    
    Commit 8b3d2254 ("The ibv_cmd_* create functions need to set context")
    breaks things when a low-level driver does not actually use an
    ibv_cmd_* function to create an object, since then the context member
    of that object never gets set.  For example, libmthca does not nee to
    call into the kernel to create an AH, and hence ibv_destroy_ah() will
    crash because it tries to call a function pointer from the AH's
    context member, which never gets set.
    
    Fix this by adding back all the setting of context to the main verbs
    functions like ibv_create_ah() (but still leave the setting in the
    ibv_cmd_* create functions too).  This means context gets set twice,
    but that doesn't really hurt anything.  Once we branch off libibverbs
    1.1 as stable, we can change the signatures of the ibv_cmd_* destroy
    functions to take an explicit context parameter, and get rid of
    setting context in the ibv_cmd_* create functions.

    Rename Debian package back to libibverbs1
    
    Since commit fd448acc ("Add ABI compatibility for apps linked against
    libibverbs 1.0") makes libibverbs 1.1 binary compatible with
    applications linked against libibverbs 1.0 and the soname of the
    library remains at 1, change the Debian package back to libibverbs1
    instead of bumping it to libibverbs2.
    

Roland Dreier <rolandd@cisco.com>	2007-01-29

    Add ABI compatibility for apps linked against libibverbs 1.0
    
    Add a compatibility layer that allows applications (but not low-level
    drivers) linked against libibverbs 1.0 to work with libibverbs 1.1.
    This is done by using Linux's versioned symbol linking support: the
    native libibverbs entry points are given IBVERBS_1.1 versions, and
    compatibility wrappers for entry points from libibverbs 1.0 are
    created with an IBVERBS_1.0 version (to match what libibverbs 1.0
    exported).
    
    In essense these wrappers create compatible proxies for every
    structure returned to the application (struct ibv_device, ibv_context,
    ibv_pd, etc), and map between the proxy and the real object when the
    application calls into libibverbs.  This code is mostly
    straightforward, with a few complications in handling async events,
    because the pointers in event structures must be translated back to
    proxy structures when they are returned to the application.
    
    There are a few further wrinkles because the calls to data path
    functions (poll CQ, post send, etc) are actually inline functions that
    call directly into the context ops, so the context ops proxy structure
    must actually contain pointers to compatibility wrappers for these
    functions as well.  This may have some performance impact but it seems
    the overhead is unavoidable, and tests with NetPIPE on top of Open MPI
    shows that the latency and throughput differences seem to be lost in
    the noise anyway.

    Implement new method for finding and loading device-specific drivers
    
    Export an ibv_register_driver() entry point, and expect plugins to
    call it from __attribute__((constructor)) code.  This will allow
    multiple drivers to be statically linked in.
    
    Also read config files and then use dlopen() with a relative path to
    find drivers (rather than searching a specific lib/infiniband/
    directory for .so files).  This allows multiple versions of a driver
    to be installed in parallel, and also allows for optimized drivers in
    places like /lib/i686.
    
    Drivers should no longer export an ibv_driver_init() function any
    more.  Instead, they should add a function (which can be static) with
    __attribute__((constructor)) that calls ibv_register_driver() to
    register the driver's probe function.  Also, drivers should install a
    file with a line "driver <driver name>" under ${sysconfdir}/libibverbs.d.

    Add a request for ChangeLog entries to the README
    

Michael S. Tsirkin <mst@mellanox.co.il>	2006-05-22

    Get rid of commas at end of enum lists
    
    While comma at end of enumerator list is legal since 1999, some tools
    (notably gcc versions pre-4.0) seem to default to 1989 mode when
    running with -pedantic flag, and warn about this usage.
    
    Since most of our enums in header files do not have comma at end, its
    probably easier to fix the remaining two cases than educate all users
    of libibverbs on virtues of C99.
    

Roland Dreier <rolandd@cisco.com>	2006-05-04

    Fix memory leak in ibv_read_sysfs_file()
    

Roland Dreier <rolandd@cisco.com>	2006-04-11

    Reduce dependency on libsysfs
    
    Reduce libibverbs dependency on libsysfs by using local functions for
    internal sysfs access.  libsysfs is still required because of the ABI,
    which passes a struct sysfs_class_device * to low-level driver init
    functions.
    

Roland Dreier <rolandd@cisco.com>	2006-04-11

    Deprecate "ib_XXX" names

    Arm CQ early enough in pingpong examples
    
    The example pingpong programs have a race when using events where the
    client sends the first packet but the server hasn't yet armed the CQ
    by calling ibv_req_notify_cq() thus waiting forever in
    ibv_get_cq_event().  The fix is to move the call to
    ibv_req_notify_cq() before signaling the client to "start".

    Improve ibv_free_device_list() documentation
    

Shirley Ma <xma@us.ibm.com>	2005-12-15

    Handle devices that don't support SRQ
    
    create_srq is not a mandatory device function, therefore in
    userspace/libibverbs/src/verbs.c ibv_create_srq should check
    create_srq() first before calling it, otherwise the caller will cause
    the segmentation fault on device which doesn't support SRQs.
    

Roland Dreier <rolandd@cisco.com>	2005-12-14

    Change from ibv_get_devices() to ibv_get_device_list()

Roland Dreier <rolandd@cisco.com>	2005-10-26

    Roll libibverbs 1.0-rc4 release
    

Roland Dreier <rolandd@cisco.com>	2005-10-25

    Fix QP attr masks in ibv_uc_pingpong
    
    Fix QP attribute masks used in ibv_uc_pingpong -- now that mthca
    correctly fails if we try to set RDMA/atomic capabilities for UC QPs,
    the examples need to be fixed as well.
    

Roland Dreier <rolandd@cisco.com>	2005-10-25

    Handle out-of-order completions in pingpong examples
    
    Keep track of whether send and/or receive is pending in libibverbs
    pingpong examples.  This avoids failures when the remote side receives
    data and posts a send very quickly, and the local side completes the
    receive before the previous send.  With the old code, this could
    result in posting a send before the previous send completed, and
    therefore overrun the send queue.
    

Roland Dreier <rolandd@cisco.com>	2005-10-25

    Fix "Source:" line in RPM spec files to be a valid URL
    

Roland Dreier <rolandd@cisco.com>	2005-10-23

    Fix buffer size computation in ibv_cmd_get_context_v2()
    
    Correct silly mistake in ibv_cmd_get_context_v2() computation of size
    of buffer for old ABI command: we need to use sizeof *cmd instead of
    sizeof cmd, since cmd is a pointer.
    

Roland Dreier <rolandd@cisco.com>	2005-10-23

    Move where we set qp->qp_type from cmd.c to verbs.c
    
    Just to be really anal.
    

Roland Dreier <rolandd@cisco.com>	2005-10-21

    Check write() return value against size we tried to write
    
    In libibverbs post send, post recv and post SRQ recv marshalling code,
    correct value that we check write() return value against so that we
    check against the size we actually try to write, instead of just
    sizeof cmd.
    

Roland Dreier <rolandd@cisco.com>	2005-10-19

    Correct sense of solicited_only parameter to ibv_cm_req_notify_cq()
    

Roland Dreier <rolandd@cisco.com>	2005-10-17

    Print components of firmware version in hex
    

Roland Dreier <rolandd@cisco.com>	2005-09-09

    Make command structure sizes the same on 32-bit and 64-bit
    
    Add 4-byte reserved members to the new destroy CQ, destroy QP and
    destroy SRQ command structures so that they become a multiple of 8
    bytes in size.  This fixes the structures so they have the same size
    on both 32-bit and 64-bit architectures (which is required so that
    32-bit userspace on a 64-bit kernel works correctly).
    

Roland Dreier <rolandd@cisco.com>	2005-09-07

    Make sure __BYTE_ORDER is defined
    
    Fail compilation if __BYTE_ORDER is neither __LITTLE_ENDIAN nor __BIG_ENDIAN.
    

Roland Dreier <rolandd@cisco.com>	2005-09-07

    Include htonll() and nothll() in <infiniband/arch.h>
    
    Move htonll() and ntohll() from libmthca into libibverb's
    <infiniband/arch.h>, and use them in ibv_get_device_guid() to
    avoid pointer aliasing (which some versions of gcc miscompile).
    

Roland Dreier <rolandd@cisco.com>	2005-09-07

    Update libibverbs for stale completion event handling
    

Roland Dreier <rolandd@cisco.com>	2005-08-31

    Add missing half of change log entry
    

Roland Dreier <rolandd@cisco.com>	2005-08-31

    Add -dbg packages with debugging symbols to Debian packages
    

Roland Dreier <rolandd@cisco.com>	2005-08-31

    Update for new kernel ABI (stale event handling)
    
    Update to handle new kernel ABI for avoiding stale asynchronous
    events.  When a CQ, QP or SRQ is destroyed, the kernel reports the
    number of events it has given to userspace, and we wait until we've
    handled the same number of events.
    
    This does introduce a library API change: consumers are now required
    to call ibv_put_async_event() to release every asynchronous event that
    they retrieve via ibv_get_async_event().
    

Roland Dreier <rolandd@cisco.com>	2005-08-31

    Add man pages for libibverbs example programs
