11 Unless you really know what you are doing, you should say Y here.
12 The reason is that some programs need kernel networking support even
13 when running on a stand-alone machine that isn't connected to any
Sam Ravnborgd5950b42005-07-11 21:03:49 -070014 other computer.

16 If you are upgrading from an older kernel, you
Linus Torvalds1da177e2005-04-16 15:20:36 -070017 should consider updating your networking tools too because changes
18 in the kernel and the tools often go hand in hand. The tools are
19 contained in the package net-tools, the location and version number
20 of which are given in <file:Documentation/Changes>.
21
22 For a general introduction to Linux networking, it is highly
23 recommended to read the NET-HOWTO, available from
24 <http://www.tldp.org/docs.html#howto>.

39 This option makes it possible to send different netlink messages
40 to tasks depending on whether the task is a compat task or not. To
41 achieve this, you need to set skb_shinfo(skb)->frag_list to the
42 compat skb before sending the skb, the netlink code will sort out
43 which message to actually pass to the task.
44
45 Newly written code should NEVER need this option but do

Pablo Neira Ayusoef91fd52006-11-29 02:35:43 +0100119 bool "Network packet filtering framework (Netfilter)"
Linus Torvalds1da177e2005-04-16 15:20:36 -0700120 ---help---
121 Netfilter is a framework for filtering and mangling network packets
122 that pass through your Linux box.
123
124 The most common use of packet filtering is to run your Linux box as
125 a firewall protecting a local network from the Internet. The type of
126 firewall provided by this kernel support is called a "packet
127 filter", which means that it can reject individual network packets
128 based on type, source, destination etc. The other kind of firewall,
129 a "proxy-based" one, is more secure but more intrusive and more
130 bothersome to set up; it inspects the network traffic much more
131 closely, modifies it and has knowledge about the higher level
132 protocols, which a packet filter lacks. Moreover, proxy-based
133 firewalls often require changes to the programs running on the local
134 clients. Proxy-based firewalls don't need support by the kernel, but
135 they are often combined with a packet filter, which only works if
136 you say Y here.
137
138 You should also say Y here if you intend to use your Linux box as
139 the gateway to the Internet for a local network of machines without
140 globally valid IP addresses. This is called "masquerading": if one
141 of the computers on your local network wants to send something to
142 the outside, your box can "masquerade" as that computer, i.e. it
143 forwards the traffic to the intended outside destination, but
144 modifies the packets to make it look like they came from the
145 firewall box itself. It works both ways: if the outside host
146 replies, the Linux box will silently forward the traffic to the
147 correct local computer. This way, the computers on your local net
148 are completely invisible to the outside world, even though they can
149 reach the outside and can receive replies. It is even possible to
150 run globally visible servers from within a masqueraded local network
151 using a mechanism called portforwarding. Masquerading is also often
152 called NAT (Network Address Translation).
153
154 Another use of Netfilter is in transparent proxying: if a machine on
155 the local network tries to connect to an outside host, your Linux
156 box can transparently forward the traffic to a local server,
157 typically a caching proxy server.
158
159 Yet another use of Netfilter is building a bridging firewall. Using
160 a bridge with Network packet filtering enabled makes iptables "see"
161 the bridged traffic. For filtering on the lower network and Ethernet
162 protocols over the bridge, use ebtables (under bridge netfilter
163 configuration).
164
165 Various modules exist for netfilter which replace the previous
166 masquerading (ipmasqadm), packet filtering (ipchains), transparent
167 proxying, and portforwarding mechanisms. Please see
168 <file:Documentation/Changes> under "iptables" for the location of
169 these packages.

313 The network stack has to drop packets when a receive processing CPU's
314 backlog reaches netdev_max_backlog. If a few out of many active flows
315 generate the vast majority of load, drop their traffic earlier to
316 maintain capacity for the other flows. This feature provides servers
317 with many clients some protection against DoS by a single (spoofed)
318 flow that greatly exceeds average workload.
