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>.

22 For a general introduction to Linux networking, it is highly
23 recommended to read the NET-HOWTO, available from

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 +0100115 bool "Network packet filtering framework (Netfilter)"
Linus Torvalds1da177e2005-04-16 15:20:36 -0700116 ---help---
117 Netfilter is a framework for filtering and mangling network packets
118 that pass through your Linux box.
119
120 The most common use of packet filtering is to run your Linux box as
121 a firewall protecting a local network from the Internet. The type of
122 firewall provided by this kernel support is called a "packet
123 filter", which means that it can reject individual network packets
124 based on type, source, destination etc. The other kind of firewall,
125 a "proxy-based" one, is more secure but more intrusive and more
126 bothersome to set up; it inspects the network traffic much more
127 closely, modifies it and has knowledge about the higher level
128 protocols, which a packet filter lacks. Moreover, proxy-based
129 firewalls often require changes to the programs running on the local
130 clients. Proxy-based firewalls don't need support by the kernel, but
131 they are often combined with a packet filter, which only works if
132 you say Y here.
133
134 You should also say Y here if you intend to use your Linux box as
135 the gateway to the Internet for a local network of machines without
136 globally valid IP addresses. This is called "masquerading": if one
137 of the computers on your local network wants to send something to
138 the outside, your box can "masquerade" as that computer, i.e. it
139 forwards the traffic to the intended outside destination, but
140 modifies the packets to make it look like they came from the
141 firewall box itself. It works both ways: if the outside host
142 replies, the Linux box will silently forward the traffic to the
143 correct local computer. This way, the computers on your local net
144 are completely invisible to the outside world, even though they can
145 reach the outside and can receive replies. It is even possible to
146 run globally visible servers from within a masqueraded local network
147 using a mechanism called portforwarding. Masquerading is also often
148 called NAT (Network Address Translation).
149
150 Another use of Netfilter is in transparent proxying: if a machine on
151 the local network tries to connect to an outside host, your Linux
152 box can transparently forward the traffic to a local server,
153 typically a caching proxy server.
154
155 Yet another use of Netfilter is building a bridging firewall. Using
156 a bridge with Network packet filtering enabled makes iptables "see"
157 the bridged traffic. For filtering on the lower network and Ethernet
158 protocols over the bridge, use ebtables (under bridge netfilter
159 configuration).
160
161 Various modules exist for netfilter which replace the previous
162 masquerading (ipmasqadm), packet filtering (ipchains), transparent
163 proxying, and portforwarding mechanisms. Please see
164 <file:Documentation/Changes> under "iptables" for the location of
165 these packages.

303 Enabling this allows a stream parser to be used with
304 BPF_MAP_TYPE_SOCKMAP.
305
306 BPF_MAP_TYPE_SOCKMAP provides a map type to use with network sockets.
307 It can be used to enforce socket policy, implement socket redirects,
308 etc.

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

343 This feature provides an alerting service to userspace in the
344 event that packets are discarded in the network stack. Alerts
345 are broadcast via netlink socket to any listening user space
346 process. If you don't need network drop alerts, or if you are ok
347 just checking the various proc files and other utilities for
348 drop statistics, say N here.
