The contents of the buffer are copied and transparently passed to the remote side as part of the communication request. May be NULL if private_data is not required. .IP private_data_len Specifies the size of the user-controlled data buffer. Note that the actual amount of data transferred to the remote side is transport dependent and may be larger than that requested. .IP responder_resources The maximum number of outstanding RDMA read and atomic operations that the local side will accept from the remote side. Applies only to RDMA_PS_TCP. This value must be less than or equal to the local RDMA device attribute max_qp_rd_atom and remote RDMA device attribute max_qp_init_rd_atom.

Applies only to RDMA_PS_TCP. This value must be less than or equal to the local RDMA device attribute max_qp_init_rd_atom and remote RDMA device attribute max_qp_rd_atom. The remote endpoint can adjust this value when accepting the connection. .IP flow_control Specifies if hardware flow control is available. This value is exchanged with the remote peer and is not used to configure the QP. Applies only to RDMA_PS_TCP. .IP retry_count The maximum number of times that a data transfer operation should be retried on the connection when an error occurs. This setting controls the number of times to retry send, RDMA, and atomic operations when timeouts occur. Applies only to RDMA_PS_TCP. .IP rnr_retry_count The maximum number of times that a send operation from the remote peer should be retried on a connection after receiving a receiver not ready (RNR) error. RNR errors are generated when a send request arrives before a buffer has been posted to receive the incoming data.

This field is ignored by the library if a QP has been created on the rdma_cm_id. Applies only to RDMA_PS_TCP. .IP qp_num Specifies the QP number associated with the connection. This field is ignored by the library if a QP has been created on the rdma_cm_id. Applies only to RDMA_PS_TCP. .SH "INFINIBAND SPECIFIC" In addition to the connection properties defined above, InfiniBand QPs are configured with minimum RNR NAK timer and local ACK timeout values. The minimum RNR NAK timer value is set to 0, for a delay of 655 ms. The local ACK timeout is calculated based on the packet lifetime and local HCA ACK delay. The packet lifetime is determined by the InfiniBand Subnet Administrator and is part of the resolved route (path record) information. The HCA ACK delay is a property of the locally used HCA. .P Retry count and RNR retry count values are 3-bit values. .P The length of the private data provided by the user is limited to 56 bytes for RDMA_PS_TCP, or 180 bytes for RDMA_PS_UDP. .SH "IWARP SPECIFIC" Connections established over iWarp RDMA devices currently require that the active side of the connection send the first message. .SH "SEE ALSO" rdma_cm(7), rdma_create_id(3), rdma_resolve_route(3), rdma_disconnect(3), rdma_listen(3), rdma_get_cm_event(3) librdmacm-1.0.16/man/rdma_create_srq.30000644000000000000000000000342612000056447014415 00000000000000.TH "RDMA_CREATE_SRQ" 3 "2011-06-15" "librdmacm" "Librdmacm Programmer's Manual" librdmacm .SH NAME rdma_create_srq \- Allocate a shared receive queue. .SH SYNOPSIS .B "#include " .P .B "int" rdma_create_srq .BI "(struct rdma_cm_id *" id "," .BI "struct ibv_pd *" pd "," .BI "struct ibv_srq_init_attr *" attr ");" .SH ARGUMENTS .IP "id" 12 RDMA identifier. .IP "pd" 12 Optional protection domain for the SRQ. .IP "attr" 12 Initial SRQ attributes. .SH "DESCRIPTION" Allocate a SRQ associated with the specified rdma_cm_id. .SH "RETURN VALUE" Returns 0 on success, or -1 on error.

It provides an RDMA transport neutral interface for establishing connections. The API concepts are based on sockets, but adapted for queue pair (QP) based semantics: communication must be over a specific RDMA device, and data transfers are message based. .P The RDMA CM can control both the QP and communication management (connection setup / teardown) portions of an RDMA API, or only the communication management piece. It works in conjunction with the verbs API defined by the libibverbs library. The libibverbs library provides the underlying interfaces needed to send and receive data. .P The RDMA CM can operate asynchronously or synchronously. The mode of operation is controlled by the user through the use of the rdma_cm event channel parameter in specific calls. If an event channel is provided, an rdma_cm identifier will report its event data (results of connecting, for example), on that channel. If a channel is not provided, then all rdma_cm operations for the selected rdma_cm identifier will block until they complete. .SH "RDMA VERBS" The rdma_cm supports the full range of verbs available through the libibverbs library and interfaces. However, it also provides wrapper functions for some of the more commonly used verbs funcationality. The full set of abstracted verb calls are: .P rdma_reg_msgs - register an array of buffers for sending and receiving .P rdma_reg_read - registers a buffer for RDMA read operations .P rdma_reg_write - registers a buffer for RDMA write operations .P rdma_dereg_mr - deregisters a memory region .P rdma_post_recv - post a buffer to receive a message .P rdma_post_send - post a buffer to send a message .P rdma_post_read - post an RDMA to read data into a buffer .P rdma_post_write - post an RDMA to send data from a buffer .P rdma_post_recvv - post a vector of buffers to receive a message .P rdma_post_sendv - post a vector of buffers to send a message .P rdma_post_readv - post a vector of buffers to receive an RDMA read .P rdma_post_writev - post a vector of buffers to send an RDMA write .P rdma_post_ud_send - post a buffer to send a message on a UD QP .P rdma_get_send_comp - get completion status for a send or RDMA operation .P rdma_get_recv_comp - get information about a completed receive .SH "CLIENT OPERATION" This section provides a general overview of the basic operation for the active, or client, side of communication. This flow assume asynchronous operation with low level call details shown. For synchronous operation, calls to rdma_create_event_channel, rdma_get_cm_event, rdma_ack_cm_event, and rdma_destroy_event_channel would be eliminated. Abstracted calls, such as rdma_create_ep encapsulate serveral of these calls under a single API. Users may also refer to the example applications for code samples. A general connection flow would be: .IP rdma_getaddrinfo retrieve address information of the destination .IP rdma_create_event_channel create channel to receive events .IP rdma_create_id allocate an rdma_cm_id, this is conceptually similar to a socket .IP rdma_resolve_addr obtain a local RDMA device to reach the remote address .IP rdma_get_cm_event wait for RDMA_CM_EVENT_ADDR_RESOLVED event .IP rdma_ack_cm_event ack event .IP rdma_create_qp allocate a QP for the communication .IP rdma_resolve_route determine the route to the remote address .IP rdma_get_cm_event wait for RDMA_CM_EVENT_ROUTE_RESOLVED event .IP rdma_ack_cm_event ack event .IP rdma_connect connect to the remote server .IP rdma_get_cm_event wait for RDMA_CM_EVENT_ESTABLISHED event .IP rdma_ack_cm_event ack event .P Perform data transfers over connection .IP rdma_disconnect tear-down connection .IP rdma_get_cm_event wait for RDMA_CM_EVENT_DISCONNECTED event .IP rdma_ack_cm_event ack event .IP rdma_destroy_qp destroy the QP .IP rdma_destroy_id release the rdma_cm_id .IP rdma_destroy_event_channel release the event channel .P An almost identical process is used to setup unreliable datagram (UD) communication between nodes. No actual connection is formed between QPs however, so disconnection is not needed. .P Although this example shows the client initiating the disconnect, either side of a connection may initiate the disconnect. .SH "SERVER OPERATION" This section provides a general overview of the basic operation for the passive, or server, side of communication. A general connection flow would be: .IP rdma_create_event_channel create channel to receive events .IP rdma_create_id allocate an rdma_cm_id, this is conceptually similar to a socket .IP rdma_bind_addr set the local port number to listen on .IP rdma_listen begin listening for connection requests .IP rdma_get_cm_event wait for RDMA_CM_EVENT_CONNECT_REQUEST event with a new rdma_cm_id .IP rdma_create_qp allocate a QP for the communication on the new rdma_cm_id .IP rdma_accept accept the connection request .IP rdma_ack_cm_event ack event .IP rdma_get_cm_event wait for RDMA_CM_EVENT_ESTABLISHED event .IP rdma_ack_cm_event ack event .P Perform data transfers over connection .IP rdma_get_cm_event wait for RDMA_CM_EVENT_DISCONNECTED event .IP rdma_ack_cm_event ack event .IP rdma_disconnect tear-down connection .IP rdma_destroy_qp destroy the QP .IP rdma_destroy_id release the connected rdma_cm_id .IP rdma_destroy_id release the listening rdma_cm_id .IP rdma_destroy_event_channel release the event channel .SH "RETURN CODES" .IP "= 0" success .IP "= -1" error - see errno for more details .P Most librdmacm functions return 0 to indicate success, and a -1 return value to indicate failure. If a function operates asynchronously, a return value of 0 means that the operation was successfully started. The operation could still complete in error; users should check the status of the related event. If the return value is -1, then errno will contain additional information regarding the reason for the failure. .P Prior versions of the library would return -errno and not set errno for some cases related to ENOMEM, ENODEV, ENODATA, EINVAL, and EADDRNOTAVAIL codes. Applications that want to check these codes and have compatability with prior library versions must manually set errno to the negative of the return code if it is < -1. .SH "SEE ALSO" rdma_accept(3), rdma_ack_cm_event(3), rdma_bind_addr(3), rdma_connect(3), rdma_create_ep(3), rdma_create_event_channel(3), rdma_create_id(3), rdma_create_qp(3), rdma_dereg_mr(3), rdma_destroy_ep(3), rdma_destroy_event_channel(3), rdma_destroy_id(3), rdma_destroy_qp(3), rdma_disconnect(3), rdma_event_str(3), rdma_free_devices(3), rdma_getaddrinfo(3), rdma_get_cm_event(3), rdma_get_devices(3), rdma_get_dst_port(3), rdma_get_local_addr(3), rdma_get_peer_addr(3), rdma_get_recv_comp(3), rdma_get_request(3), rdma_get_send_comp(3), rdma_get_src_port(3), rdma_join_multicast(3), rdma_leave_multicast(3), rdma_listen(3), rdma_migrate_id(3), rdma_notify(3), rdma_post_read(3) rdma_post_readv(3), rdma_post_recv(3), rdma_post_recvv(3), rdma_post_send(3), rdma_post_sendv(3), rdma_post_ud_send(3), rdma_post_write(3), rdma_post_writev(3), rdma_reg_msgs(3), rdma_reg_read(3), rdma_reg_write(3), rdma_reject(3), rdma_resolve_addr(3), rdma_resolve_route(3), rdma_set_option(3) mckey(1), rdma_client(1), rdma_server(1), rping(1), ucmatose(1), udaddy(1) librdmacm-1.0.16/man/rdma_post_send.30000644000000000000000000000361512000056447014263 00000000000000.TH "RDMA_POST_SEND" 3 "2010-07-19" "librdmacm" "Librdmacm Programmer's Manual" librdmacm .SH NAME rdma_post_send \- post a work request to send a message. .SH SYNOPSIS .B "#include " .P .B "int" rdma_post_send .BI "(struct rdma_cm_id *" id "," .BI "void *" context "," .BI "void *" addr "," .BI "size_t " length "," .BI "struct ibv_mr *" mr "," .BI "int " flags ");" .SH ARGUMENTS .IP "id" 12 A reference to a communication identifier where the message buffer will be posted. .IP "context" 12 User-defined context associated with the request. .IP "addr" 12 The address of the memory buffer to post. .IP "length" 12 The length of the memory buffer. .IP "mr" 12 Optional registered memory region associated with the posted buffer. .IP "flags" 12 Optional flags used to control the send operation. .SH "DESCRIPTION" Posts a work request to the send queue of the queue pair associated with the rdma_cm_id.

These options are accessible through rsetsockopt using SOL_RDMA option level. .TP RDMA_SQSIZE - Integer size of the underlying send queue. .TP RDMA_RQSIZE - Integer size of the underlying receive queue. .TP RDMA_INLINE - Integer size of inline data. .P Note that rsockets fd's cannot be passed into non-rsocket calls. For applications which must mix rsocket fd's with standard socket fd's or opened files, rpoll and rselect support polling both rsockets and normal fd's. .P Existing applications can make use of rsockets through the use of a preload library. Because rsockets implements an end-to-end protocol, both sides of a connection must use rsockets. The rdma_cm library provides such a preload library, librspreload. To reduce the chance of the preload library intercepting calls without the user's explicit knowledge, the librspreload library is installed into %libdir%/rsocket subdirectory. .P The preload library can be used by setting LD_PRELOAD when running. Note that not all applications will work with rsockets. Support is limited based on the socket options used by the application. Additionally, applications which call fork are not supported. .P rsockets uses configuration files that give an administrator control over the default settings used by rsockets. Use files under %sysconfig%/rdma/rsocket as shown: .P .P mem_default - default size of receive buffer(s) .P wmem_default - default size of send buffer(s) .P sqsize_default - default size of send queue .P rqsize_default - default size of receive queue .P inline_default - default size of inline data .P If configuration files are not available, rsockets uses internal defaults. .SH "SEE ALSO" rdma_cm(7) librdmacm-1.0.16/man/rdma_ack_cm_event.30000644000000000000000000000134412000056447014700 00000000000000.TH "RDMA_ACK_CM_EVENT" 3 "2007-05-15" "librdmacm" "Librdmacm Programmer's Manual" librdmacm .SH NAME rdma_ack_cm_event \- Free a communication event. .SH SYNOPSIS .B "#include " .P .B "int" rdma_ack_cm_event .BI "(struct rdma_cm_event *" event ");" .SH ARGUMENTS .IP "event" 12 Event to be released. .SH "DESCRIPTION" All events which are allocated by rdma_get_cm_event must be released, there should be a one-to-one correspondence between successful gets and acks.

See CONNECTION PROPERTIES below for details. .SH "DESCRIPTION" Called from the listening side to accept a connection or datagram service lookup request. .SH "RETURN VALUE" Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason. .SH "NOTES" Unlike the socket accept routine, rdma_accept is not called on a listening rdma_cm_id. Instead, after calling rdma_listen, the user waits for an RDMA_CM_EVENT_CONNECT_REQUEST event to occur. Connection request events give the user a newly created rdma_cm_id, similar to a new socket, but the rdma_cm_id is bound to a specific RDMA device. rdma_accept is called on the new rdma_cm_id. .SH "CONNECTION PROPERTIES" The following properties are used to configure the communication and specified by the conn_param parameter when accepting a connection or datagram communication request. Users should use the rdma_conn_param values reported in the connection request event to determine appropriate values for these fields when accepting. Users may reference the rdma_conn_param structure in the connection event directly, or can reference their own structure. If the rdma_conn_param structure from an event is referenced, the event must not be acked until after this call returns. .IP private_data References a user-controlled data buffer. The contents of the buffer are copied and transparently passed to the remote side as part of the communication request. May be NULL if private_data is not required. .IP private_data_len Specifies the size of the user-controlled data buffer. Note that the actual amount of data transferred to the remote side is transport dependent and may be larger than that requested. .IP responder_resources The maximum number of outstanding RDMA read and atomic operations that the local side will accept from the remote side. Applies only to RDMA_PS_TCP. This value must be less than or equal to the local RDMA device attribute max_qp_rd_atom, but preferably greater than or equal to the responder_resources value reported in the connect request event. .IP initiator_depth The maximum number of outstanding RDMA read and atomic operations that the local side will have to the remote side. Applies only to RDMA_PS_TCP. This value must be less than or equal to the local RDMA device attribute max_qp_init_rd_atom and the initiator_depth value reported in the connect request event. .IP flow_control Specifies if hardware flow control is available. This value is exchanged with the remote peer and is not used to configure the QP. Applies only to RDMA_PS_TCP. .IP retry_count This value is ignored. .IP rnr_retry_count The maximum number of times that a send operation from the remote peer should be retried on a connection after receiving a receiver not ready (RNR) error. RNR errors are generated when a send request arrives before a buffer has been posted to receive the incoming data. Applies only to RDMA_PS_TCP. .IP srq Specifies if the QP associated with the connection is using a shared receive queue. This field is ignored by the library if a QP has been created on the rdma_cm_id. Applies only to RDMA_PS_TCP. .IP qp_num Specifies the QP number associated with the connection. This field is ignored by the library if a QP has been created on the rdma_cm_id. .SH "INFINIBAND SPECIFIC" In addition to the connection properties defined above, InfiniBand QPs are configured with minimum RNR NAK timer and local ACK timeout values. The minimum RNR NAK timer value is set to 0, for a delay of 655 ms. The local ACK timeout is calculated based on the packet lifetime and local HCA ACK delay. The packet lifetime is determined by the InfiniBand Subnet Administrator and is part of the route (path record) information obtained by the active side of the connection. The HCA ACK delay is a property of the locally used HCA. .P The RNR retry count is a 3-bit value. .P The length of the private data provided by the user is limited to 196 bytes for RDMA_PS_TCP, or 136 bytes for RDMA_PS_UDP. .SH "SEE ALSO" rdma_listen(3), rdma_reject(3), rdma_get_cm_event(3) librdmacm-1.0.16/librdmacm.spec0000644000000000000000000000330312000056667013227 00000000000000%define ver 1.0.16 Name: librdmacm Version: 1.0.16 Release: 1%{?dist} Summary: Userspace RDMA Connection Manager Group: System Environment/Libraries License: GPLv2 or BSD Url: http://www.openfabrics.org/ Source: http://www.openfabrics.org/downloads/rdmacm/%{name}-%{version}.tar.gz BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n) BuildRequires: libibverbs-devel >= 1.1-1 %description librdmacm provides a userspace RDMA Communication Managment API. %package devel Summary: Development files for the librdmacm library Group: System Environment/Libraries Requires: %{name} = %{version}-%{release} %{_includedir}/infiniband/verbs.h %description devel Development files for the librdmacm library. %package utils Summary: Examples for the librdmacm library Group: System Environment/Libraries Requires: %{name} = %{version}-%{release} %description utils Example test programs for the librdmacm library. %prep %setup -q -n %{name}-%{ver} %build %configure make %{?_smp_mflags} %install rm -rf $RPM_BUILD_ROOT %makeinstall # remove unpackaged files from the buildroot rm -f $RPM_BUILD_ROOT%{_libdir}/*.la rm -f $RPM_BUILD_ROOT%{_libdir}/rsocket/*.la %clean rm -rf $RPM_BUILD_ROOT %post -p /sbin/ldconfig %postun -p /sbin/ldconfig %files %defattr(-,root,root,-) %{_libdir}/lib*.so.* %{_libdir}/rsocket/lib*.so.* %doc AUTHORS COPYING README %files devel %defattr(-,root,root) %{_libdir}/librdmacm*.so %{_libdir}/rsocket/librspreload*.so %{_libdir}/*.a %{_libdir}/rsocket/*.a %{_includedir}/* %{_mandir}/man3/* %{_mandir}/man7/* %files utils %defattr(-,root,root,-) %{_bindir}/* %{_mandir}/man1/* %changelog * Fri Feb 15 2008 Roland Dreier - 1.0.6-1 - Initial Fedora spec file librdmacm-1.0.16/src/0000755000000000000000000000000012000056657011270 500000000000000librdmacm-1.0.16/src/rsocket.c0000644000000000000000000013176512000056447013040 00000000000000/* * Copyright (c) 2008-2012 Intel Corporation.

Building ======== To make this directory, run: ./autogen.sh && ./configure && make && make install Typically the autogen and configure steps only need be done the first time unless configure.in or Makefile.am changes. Libraries are installed by default at /usr/local/lib. Device files ============ The userspace CMA uses a single device file regardless of the number of adapters or ports present. To create the appropriate character device file automatically with udev, a rule like KERNEL="rdma_cm", NAME="infiniband/%k", MODE="0666" can be used. This will create the device node named /dev/infiniband/rdma_cm or you can create it manually mknod /dev/infiniband/rdma_cm c 231 255 Common issues ============= Using multiple interfaces The librdmacm does support multiple interfaces. To make use of multiple interfaces, however, you need to instruct linux to only send ARP reples on the interface targetted in the ARP request. This can be done using a command similar to the following: sysctl -w net.ipv4.conf.all.arp_ignore=2 Without this change, it's possible for linux to resopnd to ARP requests on a different interface (IP address) than the IP address carried in the ARP request. This causes the RDMA stack to incorrectly map the remote IP address to the wrong RDMA device. Using loopback The librdmacm relies on ARP to resolve IP address to RDMA addresses. To support loopback connections between different ports on the same system, ARP must be enabled for local resolution: sysctl net.ipv4.conf.all.accept_local=1 Without this setting, loopback connections may timeout during address resolution. librdmacm-1.0.16/aclocal.m40000644000000000000000000115425212000056464012267 00000000000000# generated automatically by aclocal 1.11.1 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005, 2006, 2007, 2008, 2009 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.63],, [m4_warning([this file was generated for autoconf 2.63.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. librdmacm-1.0.16/configure.in0000644000000000000000000000573112000056447012735 00000000000000dnl Process this file with autoconf to produce a configure script.
