A: Subscribe to annopunce@openoverlayrouter.org mailing list at http://mail.openoverlayrouter.org/mailman/listinfo Q: How can I contact Open Overlay Router team? A: You can send your question regarding general usage of Open Overlay Router to users@openoverlayrouter.org. For development question or suggestions you can use devel@openoverlayrouter.org. Those lists are open and anyone can subscribe at http://mail.openoverlayrouter.org/mailman/listinfoo. When possible use those mailing lists instead of sending mails directly to us. Q: What is LISP Beta-Network? How can I join? A: You will find all the information here: http://www.lisp4.net You can request joining the Beta-Network using the form on http://www.lisp4.net/beta-network/get-involved/. Q: I am using the Beta-Network, how can I check if I registered correctly? A: The real-time state of the Beta-Network can be check by anyone, look for your EID prefix here: http://www.lisp4.net/lisp-site/ Q: How can I enable different debug levels? A: Launch oor with the -d N option, being N the debug level you want. There are three debug levels, from 1 the less verbose to 3 the most. Level 1 or 2 should be enough for common debug. You can also use the configuration file to set the default debug level. Q: How can I check the incoming/outcoming packets on my system? A: Use a tool like Wireshark. You can listen on the physical interface(s) you are using to see encapsulated packets or listen on the oor TUN interface (oorTun0) to see packets before/after being encapsulated. TUN interface will only appear when Open Overlay Router is running. To look for LISP control or LISP data packets use 'lisp' and 'lisp-data' filters. Q: How can I send ad-hoc LISP Map-Request to the LISP Mapping-System? A: Use the 'lig' tool: https://github.com/LISPmob/lig Note that lig can not be used while Open Overlay Router is running. Q: I obtain no reply to any LISP packets. I see no reply to them in any interface. A: Check that there is no firewall blocking LISP packets. LISP uses UDP port 4341 for data and 4342 for control. Both ports must be open in any firewall on the path. Q: I obtain no reply to my traffic, however I can see how reply traffic is reaching the external physical interface A: Check that Reverse Path filtering is disabled. Add the following lines to /etc/sysctl.conf and reboot the system net.ipv4.conf.default.rp_filter=0 net.ipv4.conf.all.rp_filter=0 Q: My packets are not beeing forwarded A: Check that IP forwarding is enabled on your system. Add the following lines to /etc/sysctl.conf and reboot the system net.ipv4.ip_forward=1 net.ipv6.conf.all.forwarding=1 Q: The debug output shows this message, "forward_native: No output interface found". A: This doesn't mean that Open Overlay Router is not working properly. It just means that it has tried to send a packet natively and it has not found a suitable interface. This can happen, for instance, if you are using IPv4 EIDs with IPv4 only interfaces and your system is generating IPv6 packets Q: The debug output shows this message, "The entry X.X.X.X is not found in the data base" or this one, "X.X.X.X is not a local EID" A: This message appears only when an EID is not found on the local database (the one that stores the EIDs assigned to OOR xTR/MN). Before encapsulating a packet, Open Overlay Router checks if the source address is a local EID (looking into the local database and hence printing this debug message). This is done to avoid encapsulating packets which are not meant to. Like packets originated in the xTR itself and not in the EID subnet, or packets addressed to a host on the same subnet on MN operation. Q: The debug output shows this message, "CRIT: No default output interface. Exiting ..." A: Check that the interface name defined in the "database-mapping" in your config file matches the one you want to use as RLOC interface Q: I want to use multihoming in my OpenWRT router A: Most of OpenWRT routers doesn't have more than one wan interface. To enable multihoming support in your OpenWRT router, you should create a virtual interface to be used as a second WAN. You have to assign a different VLAN to each port you want to use as WAN. Check OpenWRT documentation to see how to configure VLANs in your router. Note that not all routers have support for VLANs, and the ports used in network configuration not always match physical ports. Check the OpenWRT wiki to find documentation on your specific router. Q: I am testing multihoming on OpenWRT using a virtual WAN interface and I see strange behaviour when I force up/down on the virtual interface. A: There is a known issue with virtual WAN interfaces on OpenWRT and Open Overlay Router. On normal operation you should not expect any issue, but if you force up/down on the interface Opne Overlay Router will not behave as it would do with a physical interface. We are looking into how to solve this. oor-1.2.0/LICENSE000066400000000000000000000261361313612200500133170ustar00rootroot00000000000000 Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.

There are two implementations of Open Overlay Router merged in a single application, for rooted devices and for non-rooted devices. The application automatically selects the implementation to run according to the features of the device. It is expected that in the future the version executed in rooted devices will provide features beyond those available on the non-root devices, however on the current version there is just one root-only feature, support for IPv6 RLOCs. In both editions, there is a limit of one single EID (IPv4 or IPv6) mapped to one or more RLOC interfaces. Even though several interfaces can be managed by Open Overlay Router at the same time, they can only be used in an active-backup fashion (no more than one interface used at once). Installation ------------ OOR requires a device with Android 4.0 or higher. Please note that due to a bug on Android 4.4.0 and onwards, OOR will not work properly in no rooted devices with Android 4.4.0, 4.4.1, 4.4.2 or 4.4.3. The bug was fixed on Android 4.4.4. To ease the installation process we strongly recommend installing OOR through Google Play (search for “open overlay router”), however you can also download a precompiled APK package file from the Open Overlay Router website or compile the app from sources yourself. In any case, if you choose to install OOR without using Google Play, the device must be configured to allow the installation of packages from "unknown sources" (System Settings -> Security -> Device Administration) To build Open Overlay Router for Android from source code we recomend you to use Android Studio with the Native Development Kit * Android Studio: [https://developer.android.com/studio/index.html] To get the latest version of the OOR source from Github: git clone git://github.com/OpenOverlayRouter/oor.git Import the android folder to Android Studio and select Build APK from the Build menu. To install the application, connect your device to the pc, select Run in the Run menu and select the device you want to install and run the application. Running Open Overlay Router --------------------------- Open Overlay Router Android application allows you to start and stop the oor daemon and edit the most important parameters of the configuration file. To access the full list of configurable parameters you have to edit manually the configuration file located in /sdcard/oor.conf. Manually edited parameters not present in the graphical configuration interface will be overwritten when using the graphical configuration editor. ** Once OOR is running, the source address of the generated traffic is your EID. It is possible that the DNS server used by your device doesn't reply to unknow addresses like your new EID. We are working to try to fix this problem in a new release.** Due to the large amount of data generated by the oor daemon, it is recommended to set "log level" to 0 when not debugging. oor-1.2.0/README.md000066400000000000000000000404471313612200500135720ustar00rootroot00000000000000Overview -------- The OpenOverlayRouter (OOR) project aims to deliver a flexible and modular open-source implementation to deploy programmable overlay networks. It leverages on encapsulating overlay-specific packets into underlay-compatible packets at the edges of the instantiated overlay and route them over the physical underlying infrastructure. In order to do so, it maps overlay identifiers to underlay locators and keeps those mappings updated over time. In the current version, OOR uses the LISP protocol for the control-plane (e.g. mapping retrieval and updating, etc), NETCONF/YANG for the management-plane (e.g. overlay identifiers provisioning, etc) and can use both LISP and VXLAN-GPE headers for encapsulation. Most of the OOR architecture revolves around the LISP protocol and its components, that we introduce briefly here. The Locator/ID Separation Protocol (LISP) is an IETF protocol (RFC6830) that decouples the semantics of identity and location on current IP addresses. It uses the concept of Endpoint IDentifiers (EIDs) to name hosts in edge networks, and Routing LOCators (RLOCs) for nodes in transit networks. EIDs and RLOCs are syntactically indistinguishable from current IPv4 and IPv6 addresses, enabling backwards compatibility with the existing Internet architecture. A distributed database, the Mapping System, is responsible for maintaining the associations between EIDs and RLOCs. LISP Mobile Node (LISP-MN) is a specification to enable fast host mobility using LISP. For convenience, OOR uses terminology borrowed from the LISP protocol and thus uses the term EID for the overlay identifiers and the term RLOC for the underlay locators. Regarding the LISP devices that OOR implements, currently it can operate as an xTR, MS/MR, RTR or LISP-MN. Nowadays, OOR runs on desktop Linux, OpenWRT home routers and Android devices. The current reference platform for OOR development is Ubuntu Server 14.04.5 LTS (Trusty Tahr), OpenWRT 15.05 (Chaos Calmer) and Android 4.3 (Jelly Bean). OOR can work together with the Vector Packet Processing (VPP) technology to obtain an xTR capable to reach bandwith close to the 10 GBps. To use VPP as the OOR dataplane, refears to the README.vpp.md. OpenOverlayRouter is a rename of the LISPmob.org project. Network Prerequisites --------------------- Running a Open Overlay Router device on the public Internet requires the following: xTR - MN * an EID from a Mapping Service Provider (MSP), * the RLOC of the Map-Server that will accept the registration of this EID, * an authentication token to register the EID with the Map-Server, * the RLOC of a Map-Resolver, * the RLOC of a Proxy-ETR, * a publicly routable RLOC for the device running OOR, which is neither firewalled, nor behind NAT (see however "NAT traversal" section for details on this). RTR * the RLOC of a Map-Resolver, * a publicly routable RLOC for the device running OOR, which is neither firewalled, nor behind NAT. MS/MR * a publicly routable RLOC for the device running OOR, which is neither firewalled, nor behind NAT. The above information is used for configuring 'oor' via the configuration file 'oor.conf'. See section "OpenWRT" for OpenWRT configuration details and "Android" for Android configuration details. Visit http://www.lisp4.net/ for more info on the deployment status of the LISP beta-network and how you can join the testbed. Software Prerequisites ---------------------- To build Open Overlay Router for a standard Linux, you will need: * a Linux hosts * a C compiler (tested with `gcc`) * GNU make * git, unless you use a tarball * libConfuse * gengetopt * libcap v2+ * libzmq v3 * libxml2 On Debian-derived Linux distributions (including Ubuntu), installing the following packages will provide all necessary dependencies: * 'build-essential' * 'git-core' * 'libconfuse-dev' * 'gengetopt' * 'libcap2-bin' * 'libzmq3-dev' * 'libxml2-dev' The latest version of the Open Overlay Router source code can be obtained from Github: git clone git://github.com/OpenOverlayRouter/oor.git Installation ------------ To build the code for Linux operating run the following in the top-level directory: make To install it in `/usr/local/sbin`, run sudo make install To build the code for OpenWRT you will need the OpenWRT official SDK. However, for your convenience, we encourage you to install the precompiled .ipk, from our website. Check section "OpenWRT" for details. Running Open Overlay Router --------------------------- Once the code is successfully installed on the device, `oor.conf.example` should be copied to `/etc/oor.conf` and edited with the proper values. Again, see section 'OpenWRT' for OpenWRT details about this. Additionally the device's interface used for physical network connectivity (such as 'eth0', 'wlan0' or 'ppp0') must also be specified in the configuration file. Prior to execute Open Overlay Router, make sure that each external interface (such as 'wan0') has defined a default route with different 'metric' in the routing table (there is a 'default' entry for each outgoing interface). In most cases, this is auto-configured by the operating system during start-up. Check that sysctl options configuration is correct. Make sure that rp_filter kernel network parameter is disabled. It is disabled by default in OpenWRT, but, for instance, it is enabled by default in Ubuntu. Make sure too that IP forwarding is enabled. It should be enabled by default in OpenWRT. You can instruct your system to auto-configure these values during system boot-up if you add the following lines to `/etc/sysctl.conf`. Remember to reboot your system after adding these lines. net.ipv4.conf.default.rp_filter=0 net.ipv4.conf.all.rp_filter=0 net.ipv4.ip_forward=1 net.ipv6.conf.all.forwarding=1 The user space daemon can be started by a non privileged user with the appropriate permissions (particularly CAP_NET_ADMIN and CAP_NET_RAW). Such user can run the daemon with: oor -f /etc/oor.conf It will set up networking and register to the mapping system, after which you can enjoy all the benefits of LISP. Features -------- This is the list of supported features at this moment * xTR / MN - Register to the Mapping System - Request mappings - Reply to mapping requests - Encapsulate data packets (LISP and VXLAN-GPE) - Decapsulate data packets (LISP and VXLAN-GPE) - RLOC Probing (user configurable) - IPv6 full support (EIDs and RLOCs) - Interface management - Multihoming - Experimental NAT traversal - Explicit Locator Path (ELPs) - Instance ID / VNI support - NETCONF/YANG configurable - VPP support (only for IPv4 RLOCs) * RTR - Request mappings - Reply to mapping requests - Reencapsulate data packets (LISP and VXLAN-GPE) - RLOC Probing (user configurable) - IPv6 full support (EIDs and RLOCs) - Interface management - Multihoming - Explicit Locator Path (ELPs) - Instance ID / VNI support * MS / MR - Process registration requests - Notify correct registration - Accept more specific entries - Reply to mapping requests when Proxy Relpy activated - Forward requests to xTRs - IPv6 full support (EIDs and RLOCs) - Interface management - Explicit Locator Path (ELPs) - Instance ID support Note: OOR doesn't support overlapping local prefixes with different IIDs when operating as a XTR or MN. Mobile Node mode (MN) --------------------- When 'oor' is running in MN mode, the EID obtained configured is associated to the 'lispTun0' virtual interface. Two /1 routes covering the full IP addresses space should appear in the routing table. These routes should be pointing to 'lispTun0' device. The following lines show an example of how 'ip addr' and 'ip route' will look like with IPv4, expect a similar output with IPv6: $ ip addr 1: lo: mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff inet brd scope global eth0 valid_lft forever preferred_lft forever 3: lispTun0: mtu 1450 qdisc pfifo_fast state UNKNOWN qlen 500 link/none inet scope host lispTun0 $ ip route dev eth0 proto kernel scope link src 169.254.0.0/16 dev eth0 scope link metric 1000 0.0.0.0/1 dev lispTun0 128.0.0.0/1 dev lispTun0 default via dev eth0 metric 100 xTR mode -------- To configure Open Overlay Router to use it on xTR mode take into account the following considerations. An EID /30 (at least) prefix is required for IPv4 EIDs. For IPv6 you should have a /126 (at least). This prefix should be used as the network prefix for the subnet where the hosts on the EID space connected to the router are allocated. Assign the EID to an interface on the router and configure it as you would do for a normal network prefix (static configuration, DHCP, etc...). No EID is used for the 'lispTun0' interface in router mode (a local address is automatically used by OOR instead).

RTR mode -------- When running in RTR mode, Open Overlay Router serves as a Re-encapsulating Tunnel Router that decapsulates the received traffic to reencapsulate it again towards the next hop. To configure an RTR, select the corresponding operating-mode and fill the parameters of the RTR section and Tunnel Router general configuration of the configuration file The following lines show an example of how 'ip addr' and 'ip route' will look like with IPv4, expect a similar output with IPv6: $ ip addr 1: lo: mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff inet brd scope global eth0 valid_lft forever preferred_lft forever 3: eth1: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff inet brd scope global eth0 valid_lft forever preferred_lft forever 4: lispTun0: mtu 1440 qdisc pfifo_fast state UNKNOWN qlen 500 link/none $ ip route dev eth0 proto kernel scope link src dev eth1 proto kernel scope link src default via dev eth0 metric 100 default via dev eth1 metric 110 $ ip rule 0: from all lookup local x: from lookup x y: from lookup y 32766: from all lookup main 32767: from all lookup default MS/MR mode ---------- Open Overlay Router can be configured as a basic MS/MR where configured EID prefixes can be registered by xTRs. OOR will also reply to MapRequests addressed to those prefixes. To configure Open Overlay Router as a MS/MR, select the corresponding operating-mode and fill the parameters of the MS section of the configuration file. OpenWRT ------- To enable OpenWRT configuration mode and the specific routing operations, the code should have been compiled with the `platform=openwrt` option during OpenWRT package creation. Please note that the best way to get Open Overlay Router on OpenWRT is get a precompiled binary (either the full system or just the Open Overlay Router package) from the github website (https://github.com/OpenOverlayRouter/oor/wiki/Downloads). In OpenWRT, the configuration is performed through the OpenWRT standard configuration tool UCI, instead of using 'oor.conf' file. Configure the UCI file manually in '/etc/config/oor' (by default), use the UCI CLI application, or use the web interface (if available). The configuration fields are analogue to those in the 'oor.conf' file. Android ------- Open Overlay Router includes support for Android devices operating as LISP-MN. Please see the README.android.md file to get details on Open Overlay Router for Android installation, compilation and usage. VPP --- Open Overlay Router has adopted VPP as a new data plane that can be used to encapsulate and decapsulate LISP traffic in a high performance rate. Please see the README.vpp.md file to get details on how to configure OOR and VPP to work together. NAT traversal ------------- Since version 1.1, Open Overlay Router includes experimental NAT traversal capabilities for the modalities of xTR and MN (see LISP NAT traversal draft). In order to use NAT traversal with Open Overlay Router you will need a MS and an RTR (Re-encapsulating Tunnel Router) that are NAT traversal capable. If you are using the beta-network, please take into account that, at the time of this writing (release 1.1), not all devices on the beta-network have been updated to support NAT traversal yet. If NAT traversal feature is enabled, Open Overlay Router is configured to send all data traffic through RTRs even if the interface has a public address. On its current form, NAT traversal support on Open Overlay Router ignores IPv6 addresses on RLOC interfaces, besides, the current NAT traversal implementation in the beta-network only supports the registration of a single EID prefix per device. Contact ------- Should you have questions regarding the use of the Open Overlay Router distribution, please subscribe to the users@openoverlayrouter.org mailing list and ask there (http://mail.openoverlayrouter.org/mailman/listinfo/users). If you wish to participate in the development of Open Overlay Router, use the dedicated mailing list, devel@openoverlayrouter.org (http://mail.openoverlayrouter.org/mailman/listinfo/devel). Additionally, important announcements are sent to the low volume mailing list announce@openoverlayrouter.org (http://mail.openoverlayrouter.org/mailman/listinfo/announce). More interactive help can sometimes be obtained on the '#openoverlayrouter' IRC channel on FreeNode. Bugs you encounter should be filed at the [repository's issue tracker on Github](https://github.com/OpenOverlayRouter/oor/issues). oor-1.2.0/README.vpp.md000066400000000000000000000057111313612200500143710ustar00rootroot00000000000000VPP --- VPP is the open source version of Cisco's Vector Packet Processing (VPP) technology: a high performance, packet-processing stack that can run on commodity CPUs. Open Overlay Router has adopted VPP as an alternative data plane to kernel networking stack that can be used to encapsulate and decapsulate LISP traffic in a high performance rate close to 10 Gbps. The current integration of OOR with VPP is only supported for linux devices with network cards with DPDK support. It is limited to OOR configured as an xTR using only IPv4 RLOCs and a single default route. Installation ------------ To take advantage of VPP you will have to compile and configure it previously. If you already have installed VPP, notice that we apply a patch to the src code of VPP and more exactly to a specific commit of VPP. Without applying this patch, the integration between VPP and OOR will not work. Download the VPP code: git clone https://gerrit.fd.io/r/vpp --branch stable/1704 cd vpp git reset --hard e3b7ad7adebf25af1651a217da8534ada89c369b Patch the code before compiling: cp /VPP/vpp.patch . git apply vpp.patch Install dependecies: sudo make install-dep sudo apt-get install python-cffi python-ply python-pycparser Finally, we compile and install VPP: cd build-root ./bootstrap.sh make V=0 PLATFORM=vpp TAG=vpp install-deb sudo dpkg -i *.deb OOR compilation. Read previously the README.md file cd /oor/ make platform=vpp sudo make install Add the OOR VPP plugins: cd /VPP/oor_ctrl-plugin autoreconf -fis ./configure && make && sudo make install cd /VPP/oor_pkt_miss-plugin autoreconf -fis ./configure && make && sudo make install Configuration ------------- Here we provide you some basic instructions to configure VPP. If you want more details about VPP or how to configure it, check the wiki page of the project To assign an interface to VPP, check it is not up/configured by the Linux Kernel. If it is then shut it down: For e.g. If you want to use eth1 in vpp then: sudo ifconfig eth1 down sudo ip addr flush dev eth1 == Notice that the current version of VPP is only a traffic forwarder. Don't assign to VPP the management interface of the PC. == Start VPP: sudo service vpp start List the interfaces assigned to VPP: vppctl show interface Configure VPP interfaces: Assign an address to the interface: sudo vppctl set int ip address [del] Set status of the interface to up: sudo vppctl set int state up|down Show the interfaces addresses: vppctl show int addr If you want to use IID different to 0 (only works with local networks), you will have to do a previous step before configuring the interface associated with the EIDs: sudo vppctl set interface ip|ip6 table Once you have configured vpp you can start to use OOR. oor-1.2.0/VPP/000077500000000000000000000000001313612200500127475ustar00rootroot00000000000000oor-1.2.0/VPP/oor_ctrl-plugin/000077500000000000000000000000001313612200500160665ustar00rootroot00000000000000oor-1.2.0/VPP/oor_ctrl-plugin/Makefile.am000066400000000000000000000033671313612200500201330ustar00rootroot00000000000000# Copyright (c) 2015 Cisco and/or its affiliates. # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at: # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License.

A lot of the following document is inspired from the Linux kernel Documentation/CodingStyle file, with most of the Spaces section copied literally. A notable exception is the indentation style, which is in contradiction with the original document. Thanks to the original authors for their work! Since LISPmob is the implementation of an IETF protocol, this document uses the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", and "MAY", which are to be interpreted as described in RFC 2119. ## Indentation The code SHOULD be indented at 4 spaces, and 8 spaces (two indentation levels) SHOULD NOT be replaced by TAB characters. The only place for TABs is in Makefiles. Really. Hard drive space is really cheap these days and the amount of space saved by compacting 8 spaces into a TAB character is not worth the potential rendering errors it may cause on different systems with different settings. If you use Vim or Emacs to edit existing files, the editors will be automatically configured for the correct intendation style by the modelines at the bottom. Please place the contents of the modeline template file called `modelines` from this directory at the bottom of any new source file you may create. The `case` labels within a `switch` statement SHOULD be aligned on the same column: switch (condition) { case 'a': statement; break; case 'b': default: statement; break; } Whitespace SHOULD NOT be left at the end of lines, nor on empty lines. ## Linebreaks Lines are RECOMMENDED to be less than 80 character long and MUST NOT be longer than 132 characters. When breaking long lines into several shorter ones, syslog messages SHOULD NOT be broken, to facilitate the ability to grep for them. ## Braces Braces SHOULD be placed K&R style: opening brace last on the line, closing brace first for non-function statement blocks (if, for, do, while, switch): if (condition) { statements; } Function statement blocks have the opening brace first on the next line: int function(int x) { function body } The closing brace is alone on its own line, _except_ in the cases where it is followed by a continuation of the same statement, like: do { loop body } while (condition); and if (condition1) { statements; } else if (condition2) { statements; } else { statements; } Do not unnecessarily use braces where a single statement will do. if (condition) statement; and if (condition) statement; else statement; This does not apply if only one branch of a conditional statement is a single statement; in the latter case use braces in both branches: if (condition) { statement; statement; } else { statement; } ## Spaces The use of spaces depends (mostly) on function-versus-keyword usage. Use a space after (most) keywords. The notable exceptions are `sizeof`, `typeof`, `alignof`, and `__attribute__`, which look somewhat like functions (and are usually used with parentheses in Linux, although they are not required in the language, as in: `sizeof info` after `struct fileinfo info;` is declared). So use a space after these keywords: if, switch, case, for, do, while but not with `sizeof`, `typeof`, `alignof`, or `__attribute__`. E.g., s = sizeof(struct file); Do not add spaces around (inside) parenthesized expressions. This example is _bad_: s = sizeof( struct file ); When declaring pointer data or a function that returns a pointer type, the preferred use of `*` is adjacent to the data name or function name and not adjacent to the type name. Examples: char *linux_banner; unsigned long long memparse(char *ptr, char **retptr); char *match_strdup(substring_t *s); Use one space around (on each side of) most binary and ternary operators, such as any of these: = + - < > * / % | & ^ <= >= == != ? : but no space after unary operators: & * + - ~ ! sizeof typeof alignof __attribute__ defined no space before the postfix increment & decrement unary operators: ++ -- no space after the prefix increment & decrement unary operators: ++ -- and no space around the `.` and `->` structure member operators. Do not leave trailing whitespace at the ends of lines. Some editors with "smart" indentation will insert whitespace at the beginning of new lines as appropriate, so you can start typing the next line of code right away. However, some such editors do not remove the whitespace if you end up not putting a line of code there, such as if you leave a blank line. As a result, you end up with lines containing trailing whitespace. Git will warn you about patches that introduce trailing whitespace, and can optionally strip the trailing whitespace for you; however, if applying a series of patches, this may make later patches in the series fail by changing their context lines. ## Commenting The C89 `/* ... */` style SHOULD be used for comments, and the C99-style `//...` SHOULD NOT. The preferred style for long (multi-line) comments is: /* * This is the preferred style for multi-line * comments in the LISPmob source code. * Please use it consistently. * * Description: A column of asterisks on the left side, * with beginning and ending almost-blank lines. */ oor-1.2.0/oor/Makefile000066400000000000000000000147211313612200500145460ustar00rootroot00000000000000# #

These are functions for producing 32-bit hashes for hash table lookup. hashword(), hashlittle(), hashlittle2(), hashbig(), mix(), and final() are externally useful functions. Routines to test the hash are included if SELF_TEST is defined. You can use this free for any purpose. It's in the public domain. It has no warranty. You probably want to use hashlittle(). hashlittle() and hashbig() hash byte arrays. hashlittle() is is faster than hashbig() on little-endian machines. Intel and AMD are little-endian machines. On second thought, you probably want hashlittle2(), which is identical to hashlittle() except it returns two 32-bit hashes for the price of one. You could implement hashbig2() if you wanted but I haven't bothered here. If you want to find a hash of, say, exactly 7 integers, do a = i1; b = i2; c = i3; mix(a,b,c); a += i4; b += i5; c += i6; mix(a,b,c); a += i7; final(a,b,c); then use c as the hash value. If you have a variable length array of 4-byte integers to hash, use hashword(). If you have a byte array (like a character string), use hashlittle(). If you have several byte arrays, or a mix of things, see the comments above hashlittle(). Why is this so big? I read 12 bytes at a time into 3 4-byte integers, then mix those integers. This is fast (you can do a lot more thorough mixing with 12*3 instructions on 3 integers than you can with 3 instructions on 1 byte), but shoehorning those bytes into integers efficiently is messy. ------------------------------------------------------------------------------- Original code by Bob Jenkins.

This is reversible, so any information in (a,b,c) before mix() is still in (a,b,c) after mix(). If four pairs of (a,b,c) inputs are run through mix(), or through mix() in reverse, there are at least 32 bits of the output that are sometimes the same for one pair and different for another pair. This was tested for: * pairs that differed by one bit, by two bits, in any combination of top bits of (a,b,c), or in any combination of bottom bits of (a,b,c). * "differ" is defined as +, -, ^, or ~^. For + and -, I transformed the output delta to a Gray code (a^(a>>1)) so a string of 1's (as is commonly produced by subtraction) look like a single 1-bit difference. * the base values were pseudorandom, all zero but one bit set, or all zero plus a counter that starts at zero. Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that satisfy this are 4 6 8 16 19 4 9 15 3 18 27 15 14 9 3 7 17 3 Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing for "differ" defined as + with a one-bit base and a two-bit delta. I used http://burtleburtle.net/bob/hash/avalanche.html to choose the operations, constants, and arrangements of the variables. This does not achieve avalanche. There are input bits of (a,b,c) that fail to affect some output bits of (a,b,c), especially of a. The most thoroughly mixed value is c, but it doesn't really even achieve avalanche in c. This allows some parallelism. Read-after-writes are good at doubling the number of bits affected, so the goal of mixing pulls in the opposite direction as the goal of parallelism. I did what I could. Rotates seem to cost as much as shifts on every machine I could lay my hands on, and rotates are much kinder to the top and bottom bits, so I used rotates. ------------------------------------------------------------------------------- */ #define mix(a,b,c) \ { \ a -= c; a ^= rot(c, 4); c += b; \ b -= a; b ^= rot(a, 6); a += c; \ c -= b; c ^= rot(b, 8); b += a; \ a -= c; a ^= rot(c,16); c += b; \ b -= a; b ^= rot(a,19); a += c; \ c -= b; c ^= rot(b, 4); b += a; \ } /* ------------------------------------------------------------------------------- final -- final mixing of 3 32-bit values (a,b,c) into c Pairs of (a,b,c) values differing in only a few bits will usually produce values of c that look totally different.

For + and -, I transformed the output delta to a Gray code (a^(a>>1)) so a string of 1's (as is commonly produced by subtraction) look like a single 1-bit difference. * the base values were pseudorandom, all zero but one bit set, or all zero plus a counter that starts at zero.
