Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

14 | should consider updating your networking tools too because changes | ||
15 | in the kernel and the tools often go hand in hand. The tools are | ||
16 | contained in the package net-tools, the location and version number | ||

121 | menuconfig NETFILTER | ||
122 | bool "Network packet filtering (replaces ipchains)" | ||
123 | ---help--- | ||
124 | Netfilter is a framework for filtering and mangling network packets | ||
125 | that pass through your Linux box. | ||
126 | |||
127 | The most common use of packet filtering is to run your Linux box as | ||
128 | a firewall protecting a local network from the Internet. The type of | ||
129 | firewall provided by this kernel support is called a "packet | ||
130 | filter", which means that it can reject individual network packets | ||
131 | based on type, source, destination etc. The other kind of firewall, | ||
132 | a "proxy-based" one, is more secure but more intrusive and more | ||
133 | bothersome to set up; it inspects the network traffic much more | ||
134 | closely, modifies it and has knowledge about the higher level | ||
135 | protocols, which a packet filter lacks. Moreover, proxy-based | ||
136 | firewalls often require changes to the programs running on the local | ||
137 | clients. Proxy-based firewalls don't need support by the kernel, but | ||
138 | they are often combined with a packet filter, which only works if | ||
139 | you say Y here. | ||
140 | |||
141 | You should also say Y here if you intend to use your Linux box as | ||
142 | the gateway to the Internet for a local network of machines without | ||
143 | globally valid IP addresses. This is called "masquerading": if one | ||
144 | of the computers on your local network wants to send something to | ||
145 | the outside, your box can "masquerade" as that computer, i.e. it | ||
146 | forwards the traffic to the intended outside destination, but | ||
147 | modifies the packets to make it look like they came from the | ||
148 | firewall box itself. It works both ways: if the outside host | ||
149 | replies, the Linux box will silently forward the traffic to the | ||
150 | correct local computer. This way, the computers on your local net | ||
151 | are completely invisible to the outside world, even though they can | ||
152 | reach the outside and can receive replies. It is even possible to | ||
153 | run globally visible servers from within a masqueraded local network | ||
154 | using a mechanism called portforwarding. Masquerading is also often | ||
155 | called NAT (Network Address Translation). | ||
156 | |||
157 | Another use of Netfilter is in transparent proxying: if a machine on | ||
158 | the local network tries to connect to an outside host, your Linux | ||
159 | box can transparently forward the traffic to a local server, | ||
160 | typically a caching proxy server. | ||
161 | |||
162 | Yet another use of Netfilter is building a bridging firewall. Using | ||
163 | a bridge with Network packet filtering enabled makes iptables "see" | ||
164 | the bridged traffic. For filtering on the lower network and Ethernet | ||
165 | protocols over the bridge, use ebtables (under bridge netfilter | ||
166 | configuration). | ||
167 | |||
168 | Various modules exist for netfilter which replace the previous | ||
169 | masquerading (ipmasqadm), packet filtering (ipchains), transparent | ||
170 | proxying, and portforwarding mechanisms. Please see | ||
171 | <file:Documentation/Changes> under "iptables" for the location of | ||
172 | these packages. | ||
173 | |||
174 | Make sure to say N to "Fast switching" below if you intend to say Y | ||
175 | here, as Fast switching currently bypasses netfilter. | ||
176 | |||
177 | Chances are that you should say Y here if you compile a kernel which | ||
178 | will run as a router and N for regular hosts. If unsure, say N. | ||

294 | Several such bridges can work together to create even larger | ||
295 | networks of Ethernets using the IEEE 802.1 spanning tree algorithm. | ||
296 | As this is a standard, Linux bridges will cooperate properly with | ||
297 | other third party bridge products. | ||

441 | <file:Documentation/networking/x25.txt> and | ||
442 | <file:Documentation/networking/x25-iface.txt>. | ||
443 | |||
444 | One connects to an X.25 network either with a dedicated network card | ||
445 | using the X.21 protocol (not yet supported by Linux) or one can do | ||
446 | X.25 over a standard telephone line using an ordinary modem (say Y | ||
447 | to "X.25 async driver" below) or over Ethernet using an ordinary | ||
448 | Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link | ||
449 | Driver" and "LAPB over Ethernet driver" below). | ||

457 | ---help--- | ||
458 | Link Access Procedure, Balanced (LAPB) is the data link layer (i.e. | ||
459 | the lower) part of the X.25 protocol. It offers a reliable | ||
460 | connection service to exchange data frames with one other host, and | ||
461 | it is used to transport higher level protocols (mostly X.25 Packet | ||
462 | Layer, the higher part of X.25, but others are possible as well). | ||
463 | Usually, LAPB is used with specialized X.21 network cards, but Linux | ||
464 | currently supports LAPB only over Ethernet connections. If you want | ||
465 | to use LAPB connections over Ethernet, say Y here and to "LAPB over | ||
466 | Ethernet driver" below. Read | ||
467 | <file:Documentation/networking/lapb-module.txt> for technical | ||

475 | depends on EXPERIMENTAL | ||
476 | ---help--- | ||
477 | The Frame Diverter allows you to divert packets from the | ||
478 | network, that are not aimed at the interface receiving it (in | ||
479 | promisc. mode). Typically, a Linux box setup as an Ethernet bridge | ||
480 | with the Frames Diverter on, can do some *really* transparent www | ||
481 | caching using a Squid proxy for example. | ||
482 | |||
483 | This is very useful when you don't want to change your router's | ||
484 | config (or if you simply don't have access to it). | ||
485 | |||
486 | The other possible usages of diverting Ethernet Frames are | ||
487 | numberous: | ||
488 | - reroute smtp traffic to another interface | ||
489 | - traffic-shape certain network streams | ||
490 | - transparently proxy smtp connections | ||
491 | - etc... | ||

502 | ---help--- | ||
503 | Econet is a fairly old and slow networking protocol mainly used by | ||
504 | Acorn computers to access file and print servers. It uses native | ||
505 | Econet network cards. AUN is an implementation of the higher level | ||
506 | parts of Econet that runs over ordinary Ethernet connections, on | ||
507 | top of the UDP packet protocol, which in turn runs on top of the | ||
508 | Internet protocol IP. | ||
509 | |||
510 | If you say Y here, you can choose with the next two options whether | ||
511 | to send Econet/AUN traffic over a UDP Ethernet connection or over | ||
512 | a native Econet network card. | ||

532 | config WAN_ROUTER | ||
533 | tristate "WAN router" | ||
534 | depends on EXPERIMENTAL | ||
535 | ---help--- | ||
536 | Wide Area Networks (WANs), such as X.25, frame relay and leased | ||
537 | lines, are used to interconnect Local Area Networks (LANs) over vast | ||
538 | distances with data transfer rates significantly higher than those | ||
539 | achievable with commonly used asynchronous modem connections. | ||
540 | Usually, a quite expensive external device called a `WAN router' is | ||
541 | needed to connect to a WAN. | ||
542 | |||
543 | As an alternative, WAN routing can be built into the Linux kernel. | ||
544 | With relatively inexpensive WAN interface cards available on the | ||
545 | market, a perfectly usable router can be built for less than half | ||
546 | the price of an external router. If you have one of those cards and | ||
547 | wish to use your Linux box as a WAN router, say Y here and also to | ||
548 | the WAN driver for your card, below. You will then need the | ||
549 | wan-tools package which is available from <ftp://ftp.sangoma.com/>. | ||
550 | Read <file:Documentation/networking/wan-router.txt> for more | ||
551 | information. | ||
552 | |||
553 | To compile WAN routing support as a module, choose M here: the | ||
554 | module will be called wanrouter. | ||

560 | config NET_SCHED | ||
561 | bool "QoS and/or fair queueing" | ||
562 | ---help--- | ||
563 | When the kernel has several packets to send out over a network | ||
564 | device, it has to decide which ones to send first, which ones to | ||
565 | delay, and which ones to drop. This is the job of the packet | ||
566 | scheduler, and several different algorithms for how to do this | ||
567 | "fairly" have been proposed. | ||
568 | |||
569 | If you say N here, you will get the standard packet scheduler, which | ||
570 | is a FIFO (first come, first served). If you say Y here, you will be | ||
571 | able to choose from among several alternative algorithms which can | ||
572 | then be attached to different network devices. This is useful for | ||
573 | example if some of your network devices are real time devices that | ||
574 | need a certain minimum data flow rate, or if you need to limit the | ||
575 | maximum data flow rate for traffic which matches specified criteria. | ||
576 | This code is considered to be experimental. | ||
577 | |||
578 | To administer these schedulers, you'll need the user-level utilities | ||
579 | from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>. | ||
580 | That package also contains some documentation; for more, check out | ||
581 | <http://snafu.freedom.org/linux2.2/iproute-notes.html>. | ||
582 | |||
583 | This Quality of Service (QoS) support will enable you to use | ||
584 | Differentiated Services (diffserv) and Resource Reservation Protocol | ||
585 | (RSVP) on your Linux router if you also say Y to "QoS support", | ||
586 | "Packet classifier API" and to some classifiers below. Documentation | ||
587 | and software is at <http://diffserv.sourceforge.net/>. | ||
588 | |||
589 | If you say Y here and to "/proc file system" below, you will be able | ||
590 | to read status information about packet schedulers from the file | ||
591 | /proc/net/psched. | ||
592 | |||
593 | The available schedulers are listed in the following questions; you | ||
594 | can say Y to as many as you like. If unsure, say N now. | ||
