+ 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.

+ 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.

+ 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.
+

+
+ 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.

+
+ 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.

+
+ 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.

- * include/infiniband/verbs.h: Add enum ibv_rate to define encoding
- of static_rate field (based on a patch from Jack Morgenstein
- <jackm@mellanox.co.il>).
+ Implement PPC wmb() with sync instead of eieio
+
+ wmb() for PPC was incorrect defined as an eieio instruction in
+ libibverbs. eieio only orders pure I/O memory or a pure system memory
+ accesses. In a situation where the device drivers use the d_map
+ kernel services to share a portion of system memory with an I/O
+ adapter, we need to use sync() instead. See below link for reference:

- * src/init.c (find_drivers): Fix minor memory leak: call
- globfree() to free memory allocated by glob().
+ Revert conversion of ibv_devinfo to use ibv_port_state_str()
+
+ Using ibv_port_state_str() changes the port state output of ibv_devinfo
+ (eg "PORT_DOWN" becomes "down"), which is reported to break scripts that
+ parse this output. Revert to using the old code in ibv_devinfo; we want
+ ibv_port_state_str() to continue producing the nicer-looking lower case

+ Revert "The ibv_cmd_* create functions need to set context"
+
+ This reverts commit 5eaee85aec025be16e5aeeaac64abc6d8d9c191c.
+
+ This breaks ibv_destroy_ah() with libmthca, and isn't really appropriate

+
+ 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.

+
+ 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.

+ The ibv_cmd_* create functions need to set context
+
+ If the ibv_cmd_* create function succeeds, then the object context
+ pointer must be set by that function so that the corresponding destroy
+ function will work. This avoids problems in the error cleanup path of
+ a low-level driver's create function that fails after calling an
+ ibv_cmd_* create function.

+
+ 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.

+
+ 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.

+
+ Reduce dependency on libsysfs
+

+ 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

+ Handle devices that don't support SRQ
+
+ create_srq is not a mandatory device function, therefore in

+
+
+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.

+ Fix buffer size computation in ibv_cmd_get_context_v2()

+ Check write() return value against size we tried to write

+
+ 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().

-libibverbs (1.1.2-1) unstable; urgency=low
-
- * New upstream release.
- - Fix memory registration failure cause by too-big madvise()
- - Fix many Valgrind false positives
- - Add functions to convert enum values to strings
- * Replace deprecated ${Source-Version} with ${binary:Version}

- (Closes: #465435)
- * Add debian/watch file.
- * Update control file to talk about generic RDMA and iWARP, not just
- InfiniBand, since libibverbs works with both IB and iWARP.

-Description: A library for direct userspace use of RDMA (InfiniBand/iWARP)
- libibverbs is a library that allows userspace processes to use RDMA
- "verbs" as described in the InfiniBand Architecture Specification and
- the RDMA Protocol Verbs Specification. iWARP ethernet NICs support
- RDMA over hardware-offloaded TCP/IP, while InfiniBand is a
- high-throughput, low-latency networking technology. InfiniBand host
- channel adapters (HCAs) and iWARP NICs commonly support direct
- hardware access from userspace (kernel bypass), and libibverbs
- supports this when available.
- .
- For this library to be useful, a device-specific plug-in module
- should also be installed.
- .
- This package contains the shared library.
-

+.SH "DESCRIPTION"
+.B ibv_alloc_mw()
+allocates a memory region (MW) associated with the protection domain
+.I pd\fR.
+The MW's type (1 or 2A/2B) is
+.I type\fR.
+.PP
+The MW is created not unbounded. For it to be useful, the MW must be bounded, through either ibv_bind_mw (type 1) or a special WQE (type 2). Once bounded, the memory window allows RDMA (remote) access to a subset of the MR to which it was bounded, until invalidated/unbounded/deallocated.
+.PP
+.B ibv_dealloc_mw()
+Unbinds and deallocates the MW
+.I mw\fR.
+.SH "RETURN VALUE"
+.B ibv_alloc_mw()
+returns a pointer to the registered MW, or NULL if the request fails.
+The remote key (\fBR_Key\fR)
+field
+.B rkey
+is used by remote processes to perform Atomic and RDMA operations. This key will be changed during bind operations. The remote process places this
+.B rkey
+as the rkey field of struct ibv_send_wr passed to the ibv_post_send function.
+.PP
+.B ibv_dealloc_mw()
+returns 0 on success, or the value of errno on failure (which indicates the failure reason).
+.SH "NOTES"
+.B ibv_dereg_mr()
+fails if any memory window is still bound to this MR.

+Each header struct holds the relevant network layer parameters for matching.To enforce the match, the
+user sets a mask for each parameter. If the bit is set in the mask, the corresponding bit in the value should be matched.
+.br
+Note that most vendors support either full mask (all "1"s) or zero mask (all "0"s).
+.br
+.B Network paramters in the relevant network structs should be given in network order (big endian).
+
+.SS Flow domains and priority
+Flow steering defines the concept of domain and priority. Each domain represents a user agent that can attach a flow. The domains are prioritized. A higher priority domain will always supersede a lower priority domain when their flow specifications overlap. In addition to the domain, there is priority within each of the domains. Each domain has at most 2^12 priorities. A lower priority numeric value (higher priority) takes precedence over matching rules with higher numeric priority value (lower priority). It is important to note that the priority value of a flow spec is used not only to establish the precedence of conflicting flow matches but also as a way to abstract the order on which flow specs are tested for matches. Flows with higher priorities will be tested before flows with lower priorities.
+.br
+.B IB verbs have the higher priority domain.
+.PP
+.SS ibv_destroy_flow()

+.I flow_id\fR.

+These verbs are available only for devices supporting IBV_DEVICE_MANAGED_FLOW_STEERING and

+The bind does not complete when the function return - it is merely
+posted to the QP. The user should keep a copy of the old R_Key, and
+fix the mw structure if the subsequent CQE for the bind operation
+indicates a failure. The user may safely send the R_Key using a send
+request on the same QP, but must not transfer it to the remote in any

+.SH DESCRIPTION
+.PP
+Run efficient multi-threaded post\-send/recive test over InfiniBand via the reliable
+connected (RC) transport.
+Use different interfaces to send/recive messages and poll completions.
+Unless the '\-A' option is set, the application utilize the resource-domain verbs object to gain performance.
+The application allocates one resource-domain per application thread.
+.TP
+By using the '\-S', '\-R' and '\-P' options the application covers the following verbs interfaces:
+.TP
+ \-S
+ \tS_NORM \- ibv_post_send
+ \tS_PEND \- send_pending (member of ibv_exp_qp_burst_family)
+ \tS_PEND_INL \- send_pending_inline (member of ibv_exp_qp_burst_family)
+ \tS_PEND_SG_LIST \- send_pending_sg_list (member of ibv_exp_qp_burst_family)
+ \tS_BURST \- send_burst (member of ibv_exp_qp_burst_family)
+.TP
+ \-R
+ \tR_NORM \- ibv_post_recv
+ \tR_BURST \- recv_burst (member of ibv_exp_qp_burst_family)
+.TP
+ \-P
+ \tP_NORM \- ibv_poll_cq
+ \tP_CNT \- poll_cnt (member of ibv_exp_cq_family)
+ \tP_LEN \- poll_length (member of ibv_exp_cq_family)

.SH "DESCRIPTION"
-This library is an implementation of the verbs based on the Infiniband specification volume 1.2 chapter 11. It handles the control path of creating, modifying, querying and destroying resources such as Protection Domains (PD), Completion Queues (CQ), Queue-Pairs (QP), Shared Receive Queues (SRQ), Address Handles (AH), Memory Regions (MR). It also handles sending and receiving data posted to QPs and SRQs, getting completions from CQs using polling and completions events.
+This library is an implementation of the RDMA verbs for both Infiniband (according to the Infiniband specification volume 1, release 1.2.1) and iWarp. It handles the control path of creating, modifying, querying and destroying resources such as Protection Domains (PD), Completion Queues (CQ), Queue-Pairs (QP), Shared Receive Queues (SRQ), Address Handles (AH), Memory Regions (MR). It also handles sending and receiving data posted to QPs and SRQs, getting completions from CQs using polling and completions events.
The control path is implemented through system calls to the uverbs kernel module which further calls the low level HW driver. The data path is implemented through calls made to low level HW library which in most cases interacts directly with the HW providing kernel and network stack bypass (saving context/mode switches) along with zero copy and an asynchronous I/O model.
Typically, under network and RDMA programming, there are operations which involve interaction with remote peers (such as address resolution and connection establishment) and remote entities (such as route resolution and joining a multicast group under IB), where a resource managed through IB verbs such as QP or AH would be eventually created or effected from this interaction. In such cases, applications whose addressing semantics is based on IP can use librdmacm (see rdma_cm(7)) which works in conjunction with libibverbs.
-This library is thread safe library and verbs can be called from every thread in the process (the same resource can even be handled from different threads, for example: ibv_poll_cq can be called from more than one thread).
-
-However, it is up to the user to stop working with a resource after it was destroyed (by the same thread or by any other thread), this may result a segmentation fault.
+This library is a thread safe library and verbs can be called from every thread in the process. The same resource can even be handled from different threads (the atomicity of the operations is guaranteed). However, it is up to the user to stop working with a resource after it was destroyed (by the same thread or by any other thread), not doing so may result a segmentation fault.
If fork (or any other system call that perform fork directly or indirectly) is being used, please see ibv_fork_init(3).

+ * A: At some points, the sum (%0) was used as
+ * length-counter instead of the length counter
+ * (%1). Thanks to Roman Hodek for pointing this out.
+ * B: GCC seems to mess up if one uses too many

+ * specify d0 and d1 as scratch registers. Letting gcc
+ * choose these registers itself solves the problem.
