| 10 | INTRODUCTION |
| 11 | |
| 12 | Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs) |
| 13 | and/or stand-alone hosts over vast distances with data transfer rates |
| 14 | significantly higher than those achievable with commonly used dial-up |
| 15 | connections. |
| 16 | |
| 17 | Usually an external device called `WAN router' sitting on your local network |
| 18 | or connected to your machine's serial port provides physical connection to |
| 19 | WAN. Although router's job may be as simple as taking your local network |
| 20 | traffic, converting it to WAN format and piping it through the WAN link, these |
| 21 | devices are notoriously expensive, with prices as much as 2 - 5 times higher |
| 22 | then the price of a typical PC box. |
| 23 | |
| 24 | Alternatively, considering robustness and multitasking capabilities of Linux, |
| 25 | an internal router can be built (most routers use some sort of stripped down |
| 26 | Unix-like operating system anyway). With a number of relatively inexpensive WAN |
| 27 | interface cards available on the market, a perfectly usable router can be |
| 28 | built for less than half a price of an external router. Yet a Linux box |
| 29 | acting as a router can still be used for other purposes, such as fire-walling, |
| 30 | running FTP, WWW or DNS server, etc. |
| 31 | |
| 32 | This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux |
| 33 | operating system and provides generic hardware-independent services for such |
| 34 | drivers. Why can existing Linux network device interface not be used for |
| 35 | this purpose? Well, it can. However, there are a few key differences between |
| 36 | a typical network interface (e.g. Ethernet) and a WAN link. |
| 37 | |
| 38 | Many WAN protocols, such as X.25 and frame relay, allow for multiple logical |
| 39 | connections (known as `virtual circuits' in X.25 terminology) over a single |
| 40 | physical link. Each such virtual circuit may (and almost always does) lead |
| 41 | to a different geographical location and, therefore, different network. As a |
| 42 | result, it is the virtual circuit, not the physical link, that represents a |
| 43 | route and, therefore, a network interface in Linux terms. |
| 44 | |
| 45 | To further complicate things, virtual circuits are usually volatile in nature |
| 46 | (excluding so called `permanent' virtual circuits or PVCs). With almost no |
| 47 | time required to set up and tear down a virtual circuit, it is highly desirable |
| 48 | to implement on-demand connections in order to minimize network charges. So |
| 49 | unlike a typical network driver, the WAN driver must be able to handle multiple |
| 50 | network interfaces and cope as multiple virtual circuits come into existence |
| 51 | and go away dynamically. |
| 52 | |
| 53 | Last, but not least, WAN configuration is much more complex than that of say |
| 54 | Ethernet and may well amount to several dozens of parameters. Some of them |
| 55 | are "link-wide" while others are virtual circuit-specific. The same holds |
| 56 | true for WAN statistics which is by far more extensive and extremely useful |
| 57 | when troubleshooting WAN connections. Extending the ifconfig utility to suit |
| 58 | these needs may be possible, but does not seem quite reasonable. Therefore, a |
| 59 | WAN configuration utility and corresponding application programmer's interface |
| 60 | is needed for this purpose. |
| 61 | |
| 62 | Most of these problems are taken care of by this module. Its goal is to |
| 63 | provide a user with more-or-less standard look and feel for all WAN devices and |
| 64 | assist a WAN device driver writer by providing common services, such as: |
| 65 | |
| 66 | o User-level interface via /proc file system |
| 67 | o Centralized configuration |
| 68 | o Device management (setup, shutdown, etc.) |
| 69 | o Network interface management (dynamic creation/destruction) |
| 70 | o Protocol encapsulation/decapsulation |
| 71 | |
| 72 | To ba able to use the Linux WAN Router you will also need a WAN Tools package |
| 73 | available from |
| 74 | |
| 75 | ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz |
| 76 | |
| 77 | where vX.Y.Z represent the wanpipe version number. |

| 115 | ACKNOWLEDGEMENTS |
| 116 | |
| 117 | This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed |
| 118 | by Sangoma Technologies Inc. for Linux 2.0.x and 2.2.x. Success of the WANPIPE |
| 119 | together with the next major release of Linux kernel in summer 1996 commanded |
| 120 | adequate changes to the WANPIPE code to take full advantage of new Linux |
| 121 | features. |
| 122 | |
| 123 | Instead of continuing developing proprietary interface tied to Sangoma WAN |
| 124 | cards, we decided to separate all hardware-independent code into a separate |
| 125 | module and defined two levels of interfaces - one for user-level applications |
| 126 | and another for kernel-level WAN drivers. WANPIPE is now implemented as a |
| 127 | WAN driver compliant with the WAN Link Driver interface. Also a general |
| 128 | purpose WAN configuration utility and a set of shell scripts was developed to |
| 129 | support WAN router at the user level. |
| 130 | |
| 131 | Many useful ideas concerning hardware-independent interface implementation |
| 132 | were given by Mike McLagan <mike.mclagan@linux.org> and his implementation |
| 133 | of the Frame Relay router and drivers for Sangoma cards (dlci/sdla). |
| 134 | |
| 135 | With the new implementation of the APIs being incorporated into the WANPIPE, |
| 136 | a special thank goes to Alan Cox in providing insight into BSD sockets. |
| 137 | |
| 138 | Special thanks to all the WANPIPE users who performed field-testing, reported |
| 139 | bugs and made valuable comments and suggestions that help us to improve this |
| 140 | product. |
| 141 | |
| 142 | |
| 143 | |
| 144 | NEW IN THIS RELEASE |
| 145 | |
| 146 | o Updated the WANCFG utility |
| 147 | Calls the pppconfig to configure the PPPD |
| 148 | for async connections. |
| 149 | |
| 150 | o Added the PPPCONFIG utility |
| 151 | Used to configure the PPPD dameon for the |
| 152 | WANPIPE Async PPP and standard serial port. |
| 153 | The wancfg calls the pppconfig to configure |
| 154 | the pppd. |
| 155 | |
| 156 | o Fixed the PCI autodetect feature. |
| 157 | The SLOT 0 was used as an autodetect option |
| 158 | however, some high end PC's slot numbers start |
| 159 | from 0. |
| 160 | |
| 161 | o This release has been tested with the new backupd |
| 162 | daemon release. |

| 362 | 2.1.0 Oct 25, 1999 o New code for S514 PCI Card |
| 363 | o New CHDLC and Frame Relay drivers |
| 364 | o PPP and X25 are not supported in this release |
| 365 | |
| 366 | 2.1.1 Nov 30, 1999 o PPP support for S514 PCI Cards |
| 367 | |
| 368 | 2.1.3 Apr 06, 2000 o Socket based x25api |
| 369 | o Socket based chdlc api |
| 370 | o Socket based fr api |
| 371 | o Dual Port Receive only CHDLC support. |
| 372 | o Asynchronous CHDLC support (Secondary Port) |
| 373 | o cfgft1 GUI csu/dsu configurator |
| 374 | o wancfg GUI configuration file |
| 375 | configurator. |
| 376 | o Architectual directory changes. |
| 377 | |
| 378 | beta-2.1.4 Jul 2000 o Dynamic interface configuration: |
| 379 | Network interfaces reflect the state |
| 380 | of protocol layer. If the protocol becomes |
| 381 | disconnected, driver will bring down |
| 382 | the interface. Once the protocol reconnects |
| 383 | the interface will be brought up. |
| 384 | |
| 385 | Note: This option is turned off by default. |
| 386 | |
| 387 | o Dynamic wanrouter setup using 'wanconfig': |
| 388 | wanconfig utility can be used to |
| 389 | shutdown,restart,start or reconfigure |
| 390 | a virtual circuit dynamically. |
| 391 | |
| 392 | Frame Relay: Each DLCI can be: |
| 393 | created,stopped,restarted and reconfigured |
| 394 | dynamically using wanconfig. |
| 395 | |
| 396 | ex: wanconfig card wanpipe1 dev wp1_fr16 up |
| 397 | |
| 398 | o Wanrouter startup via command line arguments: |
| 399 | wanconfig also supports wanrouter startup via command line |
| 400 | arguments. Thus, there is no need to create a wanpipe#.conf |
| 401 | configuration file. |
| 402 | |
| 403 | o Socket based x25api update/bug fixes. |
| 404 | Added support for LCN numbers greater than 255. |
| 405 | Option to pass up modem messages. |
| 406 | Provided a PCI IRQ check, so a single S514 |
| 407 | card is guaranteed to have a non-sharing interrupt. |
| 408 | |
| 409 | o Fixes to the wancfg utility. |
| 410 | o New FT1 debugging support via *pipemon utilities. |
| 411 | o Frame Relay ARP support Enabled. |
| 412 | |
| 413 | beta3-2.1.4 Jul 2000 o X25 M_BIT Problem fix. |
| 414 | o Added the Multi-Port PPP |
| 415 | Updated utilites for the Multi-Port PPP. |
| 416 | |
| 417 | 2.1.4 Aut 2000 |
| 418 | o In X25API: |
| 419 | Maximum packet an application can send |
| 420 | to the driver has been extended to 4096 bytes. |
| 421 | |
| 422 | Fixed the x25 startup bug. Enable |
| 423 | communications only after all interfaces |
| 424 | come up. HIGH SVC/PVC is used to calculate |
| 425 | the number of channels. |
| 426 | Enable protocol only after all interfaces |
| 427 | are enabled. |
| 428 | |
| 429 | o Added an extra state to the FT1 config, kernel module. |
| 430 | o Updated the pipemon debuggers. |
| 431 | |
| 432 | o Blocked the Multi-Port PPP from running on kernels |
| 433 | 2.2.16 or greater, due to syncppp kernel module |
| 434 | change. |
| 435 | |
| 436 | beta1-2.1.5 Nov 15 2000 |
| 437 | o Fixed the MulitPort PPP Support for kernels 2.2.16 and above. |
| 438 | 2.2.X kernels only |
| 439 | |
| 440 | o Secured the driver UDP debugging calls |
| 441 | - All illegal netowrk debugging calls are reported to |
| 442 | the log. |
| 443 | - Defined a set of allowed commands, all other denied. |
| 444 | |
| 445 | o Cpipemon |
| 446 | - Added set FT1 commands to the cpipemon. Thus CSU/DSU |
| 447 | configuraiton can be performed using cpipemon. |
| 448 | All systems that cannot run cfgft1 GUI utility should |
| 449 | use cpipemon to configure the on board CSU/DSU. |
| 450 | |
| 451 | |
| 452 | o Keyboard Led Monitor/Debugger |
| 453 | - A new utilty /usr/sbin/wpkbdmon uses keyboard leds |
| 454 | to convey operatinal statistic information of the |
| 455 | Sangoma WANPIPE cards. |
| 456 | NUM_LOCK = Line State (On=connected, Off=disconnected) |
| 457 | CAPS_LOCK = Tx data (On=transmitting, Off=no tx data) |
| 458 | SCROLL_LOCK = Rx data (On=receiving, Off=no rx data |
| 459 | |
| 460 | o Hardware probe on module load and dynamic device allocation |
| 461 | - During WANPIPE module load, all Sangoma cards are probed |
| 462 | and found information is printed in the /var/log/messages. |
| 463 | - If no cards are found, the module load fails. |
| 464 | - Appropriate number of devices are dynamically loaded |
| 465 | based on the number of Sangoma cards found. |
| 466 | |
| 467 | Note: The kernel configuraiton option |
| 468 | CONFIG_WANPIPE_CARDS has been taken out. |
| 469 | |
| 470 | o Fixed the Frame Relay and Chdlc network interfaces so they are |
| 471 | compatible with libpcap libraries. Meaning, tcpdump, snort, |
| 472 | ethereal, and all other packet sniffers and debuggers work on |
| 473 | all WANPIPE netowrk interfaces. |
| 474 | - Set the network interface encoding type to ARPHRD_PPP. |
| 475 | This tell the sniffers that data obtained from the |
| 476 | network interface is in pure IP format. |
| 477 | Fix for 2.2.X kernels only. |
| 478 | |
| 479 | o True interface encoding option for Frame Relay and CHDLC |
| 480 | - The above fix sets the network interface encoding |
| 481 | type to ARPHRD_PPP, however some customers use |
| 482 | the encoding interface type to determine the |
| 483 | protocol running. Therefore, the TURE ENCODING |
| 484 | option will set the interface type back to the |
| 485 | original value. |
| 486 | |
| 487 | NOTE: If this option is used with Frame Relay and CHDLC |
| 488 | libpcap library support will be broken. |
| 489 | i.e. tcpdump will not work. |
| 490 | Fix for 2.2.x Kernels only. |
| 491 | |
| 492 | o Ethernet Bridgind over Frame Relay |
| 493 | - The Frame Relay bridging has been developed by |
| 494 | Kristian Hoffmann and Mark Wells. |
| 495 | - The Linux kernel bridge is used to send ethernet |
| 496 | data over the frame relay links. |
| 497 | For 2.2.X Kernels only. |
| 498 | |
| 499 | o Added extensive 2.0.X support. Most new features of |
| 500 | 2.1.5 for protocols Frame Relay, PPP and CHDLC are |
| 501 | supported under 2.0.X kernels. |
| 502 | |
| 503 | beta1-2.2.0 Dec 30 2000 |
| 504 | o Updated drivers for 2.4.X kernels. |
| 505 | o Updated drivers for SMP support. |
| 506 | o X25API is now able to share PCI interrupts. |
| 507 | o Took out a general polling routine that was used |
| 508 | only by X25API. |
| 509 | o Added appropriate locks to the dynamic reconfiguration |
| 510 | code. |
| 511 | o Fixed a bug in the keyboard debug monitor. |
| 512 | |
| 513 | beta2-2.2.0 Jan 8 2001 |
| 514 | o Patches for 2.4.0 kernel |
| 515 | o Patches for 2.2.18 kernel |
| 516 | o Minor updates to PPP and CHLDC drivers. |

| 519 | beta3-2.2.9 Jan 10 2001 |
| 520 | o I missed the 2.2.18 kernel patches in beta2-2.2.0 |
| 521 | release. They are included in this release. |
| 522 | |
| 523 | Stable Release |
| 524 | 2.2.0 Feb 01 2001 |
| 525 | o Bug fix in wancfg GUI configurator. |
| 526 | The edit function didn't work properly. |
| 527 | |
| 528 | |
| 529 | bata1-2.2.1 Feb 09 2001 |
| 530 | o WANPIPE TTY Driver emulation. |
| 531 | Two modes of operation Sync and Async. |
| 532 | Sync: Using the PPPD daemon, kernel SyncPPP layer |
| 533 | and the Wanpipe sync TTY driver: a PPP protocol |
| 534 | connection can be established via Sangoma adapter, over |
| 535 | a T1 leased line. |
| 536 | |
| 537 | The 2.4.0 kernel PPP layer supports MULTILINK |
| 538 | protocol, that can be used to bundle any number of Sangoma |
| 539 | adapters (T1 lines) into one, under a single IP address. |
| 540 | Thus, efficiently obtaining multiple T1 throughput. |
| 541 | |
| 542 | NOTE: The remote side must also implement MULTILINK PPP |
| 543 | protocol. |
| 544 | |
| 545 | Async:Using the PPPD daemon, kernel AsyncPPP layer |
| 546 | and the WANPIPE async TTY driver: a PPP protocol |
| 547 | connection can be established via Sangoma adapter and |
| 548 | a modem, over a telephone line. |
| 549 | |
| 550 | Thus, the WANPIPE async TTY driver simulates a serial |
| 551 | TTY driver that would normally be used to interface the |
| 552 | MODEM to the linux kernel. |
| 553 | |
| 554 | o WANPIPE PPP Backup Utility |
| 555 | This utility will monitor the state of the PPP T1 line. |
| 556 | In case of failure, a dial up connection will be established |
| 557 | via pppd daemon, ether via a serial tty driver (serial port), |
| 558 | or a WANPIPE async TTY driver (in case serial port is unavailable). |
| 559 | |
| 560 | Furthermore, while in dial up mode, the primary PPP T1 link |
| 561 | will be monitored for signs of life. |
| 562 | |
| 563 | If the PPP T1 link comes back to life, the dial up connection |
| 564 | will be shutdown and T1 line re-established. |
| 565 | |
| 566 | |
| 567 | o New Setup installation script. |
| 568 | Option to UPGRADE device drivers if the kernel source has |
| 569 | already been patched with WANPIPE. |
| 570 | |
| 571 | Option to COMPILE WANPIPE modules against the currently |
| 572 | running kernel, thus no need for manual kernel and module |
| 573 | re-compilatin. |
| 574 | |
| 575 | o Updates and Bug Fixes to wancfg utility. |
| 576 | |
| 577 | bata2-2.2.1 Feb 20 2001 |
| 578 | |
| 579 | o Bug fixes to the CHDLC device drivers. |
| 580 | The driver had compilation problems under kernels |
| 581 | 2.2.14 or lower. |
| 582 | |
| 583 | o Bug fixes to the Setup installation script. |
| 584 | The device drivers compilation options didn't work |
| 585 | properly. |
| 586 | |
| 587 | o Update to the wpbackupd daemon. |
| 588 | Optimized the cross-over times, between the primary |
| 589 | link and the backup dialup. |
| 590 | |
| 591 | beta3-2.2.1 Mar 02 2001 |
| 592 | o Patches for 2.4.2 kernel. |
| 593 | |
| 594 | o Bug fixes to util/ make files. |
| 595 | o Bug fixes to the Setup installation script. |
| 596 | |
| 597 | o Took out the backupd support and made it into |
| 598 | as separate package. |
| 599 | |
| 600 | beta4-2.2.1 Mar 12 2001 |
| 601 | |
| 602 | o Fix to the Frame Relay Device driver. |
| 603 | IPSAC sends a packet of zero length |
| 604 | header to the frame relay driver. The |
| 605 | driver tries to push its own 2 byte header |
| 606 | into the packet, which causes the driver to |
| 607 | crash. |
| 608 | |
| 609 | o Fix the WANPIPE re-configuration code. |
| 610 | Bug was found by trying to run the cfgft1 while the |
| 611 | interface was already running. |
| 612 | |
| 613 | o Updates to cfgft1. |
| 614 | Writes a wanpipe#.cfgft1 configuration file |
| 615 | once the CSU/DSU is configured. This file can |
| 616 | holds the current CSU/DSU configuration. |
