We're happy to accept contributions, whether they're fixes to old protocols, new protocols entirely, or anything else you think would improve the gopacket library. This document is designed to help you to do just that. The first section deals with the plumbing: how to actually get a change submitted. The second section deals with coding style... Go is great in that it has a uniform style implemented by 'go fmt', but there's still some decisions we've made that go above and beyond, and if you follow them, they won't come up in your code review. The third section deals with some of the implementation decisions we've made, which may help you to understand the current code and which we may ask you to conform to (or provide compelling reasons for ignoring). Overall, we hope this document will help you to understand our system and write great code which fits in, and help us to turn around on your code review quickly so the code can make it into the master branch as quickly as possible. How To Submit Code ------------------ We use github.com's Pull Request feature to receive code contributions from external contributors. See https://help.github.com/articles/creating-a-pull-request/ for details on how to create a request. Also, there's a local script `gc` in the base directory of GoPacket that runs a local set of checks, which should give you relatively high confidence that your pull won't fail github pull checks. ```sh go get github.com/google/gopacket cd $GOROOT/src/pkg/github.com/google/gopacket git checkout -b # create a new branch to work from ... code code code ... ./gc # Run this to do local commits, it performs a number of checks ``` To sum up: * DO + Pull down the latest version. + Make a feature-specific branch. + Code using the style and methods discussed in the rest of this document. + Use the ./gc command to do local commits or check correctness. + Push your new feature branch up to github.com, as a pull request. + Handle comments and requests from reviewers, pushing new commits up to your feature branch as problems are addressed. + Put interesting comments and discussions into commit comments. * DON'T + Push to someone else's branch without their permission. Coding Style ------------ * Go code must be run through `go fmt`, `go vet`, and `golint` * Follow http://golang.org/doc/effective_go.html as much as possible. + In particular, http://golang.org/doc/effective_go.html#mixed-caps. Enums should be be CamelCase, with acronyms capitalized (TCPSourcePort, vs. TcpSourcePort or TCP_SOURCE_PORT). * Bonus points for giving enum types a String() field. * Any exported types or functions should have commentary (http://golang.org/doc/effective_go.html#commentary) Coding Methods And Implementation Notes --------------------------------------- ### Error Handling Many times, you'll be decoding a protocol and run across something bad, a packet corruption or the like. How do you handle this? First off, ALWAYS report the error. You can do this either by returning the error from the decode() function (most common), or if you're up for it you can implement and add an ErrorLayer through the packet builder (the first method is a simple shortcut that does exactly this, then stops any future decoding). Often, you'll already have decode some part of your protocol by the time you hit your error. Use your own discretion to determine whether the stuff you've already decoded should be returned to the caller or not: ```go func decodeMyProtocol(data []byte, p gopacket.PacketBuilder) error { prot := &MyProtocol{} if len(data) < 10 { // This error occurred before we did ANYTHING, so there's nothing in my // protocol that the caller could possibly want. Just return the error. return fmt.Errorf("Length %d less than 10", len(data)) } prot.ImportantField1 = data[:5] prot.ImportantField2 = data[5:10] // At this point, we've already got enough information in 'prot' to // warrant returning it to the caller, so we'll add it now. p.AddLayer(prot) if len(data) < 15 { // We encountered an error later in the packet, but the caller already // has the important info we've gleaned so far. return fmt.Errorf("Length %d less than 15", len(data)) } prot.ImportantField3 = data[10:15] return nil // We've already added the layer, we can just return success. } ``` In general, our code follows the approach of returning the first error it encounters. In general, we don't trust any bytes after the first error we see. ### What Is A Layer? The definition of a layer is up to the discretion of the coder. It should be something important enough that it's actually useful to the caller (IE: every TLV value should probably NOT be a layer). However, it can be more granular than a single protocol... IPv6 and SCTP both implement many layers to handle the various parts of the protocol. Use your best judgement, and prepare to defend your decisions during code review. ;) ### Performance We strive to make gopacket as fast as possible while still providing lots of features. In general, this means: * Focus performance tuning on common protocols (IP4/6, TCP, etc), and optimize others on an as-needed basis (tons of MPLS on your network? Time to optimize MPLS!) * Use fast operations. See the toplevel benchmark_test for benchmarks of some of Go's underlying features and types. * Test your performance changes! You should use the ./gc script's --benchmark flag to submit any performance-related changes. Use pcap/gopacket_benchmark to test your change against a PCAP file based on your traffic patterns. * Don't be TOO hacky. Sometimes, removing an unused struct from a field causes a huge performance hit, due to the way that Go currently handles its segmented stack... don't be afraid to clean it up anyway. We'll trust the Go compiler to get good enough over time to handle this. Also, this type of compiler-specific optimization is very fragile; someone adding a field to an entirely different struct elsewhere in the codebase could reverse any gains you might achieve by aligning your allocations. * Try to minimize memory allocations. If possible, use []byte to reference pieces of the input, instead of using string, which requires copying the bytes into a new memory allocation. * Think hard about what should be evaluated lazily vs. not. In general, a layer's struct should almost exactly mirror the layer's frame. Anything that's more interesting should be a function. This may not always be possible, but it's a good rule of thumb. * Don't fear micro-optimizations. With the above in mind, we welcome micro-optimizations that we think will have positive/neutral impacts on the majority of workloads. A prime example of this is pre-allocating certain structs within a larger one: ```go type MyProtocol struct { // Most packets have 1-4 of VeryCommon, so we preallocate it here. initialAllocation [4]uint32 VeryCommon []uint32 } func decodeMyProtocol(data []byte, p gopacket.PacketBuilder) error { prot := &MyProtocol{} prot.VeryCommon = proto.initialAllocation[:0] for len(data) > 4 { field := binary.BigEndian.Uint32(data[:4]) data = data[4:] // Since we're using the underlying initialAllocation, we won't need to // allocate new memory for the following append unless we more than 16 // bytes of data, which should be the uncommon case. prot.VeryCommon = append(prot.VeryCommon, field) } p.AddLayer(prot) if len(data) > 0 { return fmt.Errorf("MyProtocol packet has %d bytes left after decoding", len(data)) } return nil } ``` ### Slices And Data If you're pulling a slice from the data you're decoding, don't copy it. Just use the slice itself. ```go type MyProtocol struct { A, B net.IP } func decodeMyProtocol(data []byte, p gopacket.PacketBuilder) error { p.AddLayer(&MyProtocol{ A: data[:4], B: data[4:8], }) return nil } ``` The caller has already agreed, by using this library, that they won't modify the set of bytes they pass in to the decoder, or the library has already copied the set of bytes to a read-only location. See DecodeOptions.NoCopy for more information. ### Enums/Types If a protocol has an integer field (uint8, uint16, etc) with a couple of known values that mean something special, make it a type. This allows us to do really nice things like adding a String() function to them, so we can more easily display those to users. Check out layers/enums.go for one example, as well as layers/icmp.go for layer-specific enums. When naming things, try for descriptiveness over suscinctness. For example, choose DNSResponseRecord over DNSRR. gopacket-1.1.19/LICENSE000066400000000000000000000030231374333536000144120ustar00rootroot00000000000000Copyright (c) 2012 Google, Inc.

/*
Package gopacket provides packet decoding for the Go language.

gopacket contains many sub-packages with additional functionality you may find
useful, including:

 * layers: You'll probably use this every time.  This contains of the logic
     built into gopacket for decoding packet protocols.  Note that all example
     code below assumes that you have imported both gopacket and
     gopacket/layers.
 * pcap: C bindings to use libpcap to read packets off the wire.
 * pfring: C bindings to use PF_RING to read packets off the wire.
 * afpacket: C bindings for Linux's AF_PACKET to read packets off the wire.
 * tcpassembly: TCP stream reassembly

Also, if you're looking to dive right into code, see the examples subdirectory
for numerous simple binaries built using gopacket libraries.

Minimum go version required is 1.5 except for pcapgo/EthernetHandle, afpacket,
and bsdbpf which need at least 1.7 due to x/sys/unix dependencies.

Basic Usage

gopacket takes in packet data as a []byte and decodes it into a packet with
a non-zero number of "layers".  Each layer corresponds to a protocol
within the bytes.  Once a packet has been decoded, the layers of the packet
can be requested from the packet.

 // Decode a packet
 packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Default)
 // Get the TCP layer from this packet
 if tcpLayer := packet.Layer(layers.LayerTypeTCP); tcpLayer != nil {
   fmt.Println("This is a TCP packet!")
   // Get actual TCP data from this layer
   tcp, _ := tcpLayer.(*layers.TCP)
   fmt.Printf("From src port %d to dst port %d\n", tcp.SrcPort, tcp.DstPort)
 }
 // Iterate over all layers, printing out each layer type
 for _, layer := range packet.Layers() {
   fmt.Println("PACKET LAYER:", layer.LayerType())
 }

Packets can be decoded from a number of starting points.  Many of our base
types implement Decoder, which allow us to decode packets for which
we don't have full data.

 // Decode an ethernet packet
 ethP := gopacket.NewPacket(p1, layers.LayerTypeEthernet, gopacket.Default)
 // Decode an IPv6 header and everything it contains
 ipP := gopacket.NewPacket(p2, layers.LayerTypeIPv6, gopacket.Default)
 // Decode a TCP header and its payload
 tcpP := gopacket.NewPacket(p3, layers.LayerTypeTCP, gopacket.Default)


Reading Packets From A Source

Most of the time, you won't just have a []byte of packet data lying around.
Instead, you'll want to read packets in from somewhere (file, interface, etc)
and process them.  To do that, you'll want to build a PacketSource.

First, you'll need to construct an object that implements the PacketDataSource
interface.  There are implementations of this interface bundled with gopacket
in the gopacket/pcap and gopacket/pfring subpackages... see their documentation
for more information on their usage.  Once you have a PacketDataSource, you can
pass it into NewPacketSource, along with a Decoder of your choice, to create
a PacketSource.

Once you have a PacketSource, you can read packets from it in multiple ways.
See the docs for PacketSource for more details.  The easiest method is the
Packets function, which returns a channel, then asynchronously writes new
packets into that channel, closing the channel if the packetSource hits an
end-of-file.

  packetSource := ...  // construct using pcap or pfring
  for packet := range packetSource.Packets() {
    handlePacket(packet)  // do something with each packet
  }

You can change the decoding options of the packetSource by setting fields in
packetSource.DecodeOptions... see the following sections for more details.


Lazy Decoding

gopacket optionally decodes packet data lazily, meaning it
only decodes a packet layer when it needs to handle a function call.

 // Create a packet, but don't actually decode anything yet
 packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
 // Now, decode the packet up to the first IPv4 layer found but no further.
 // If no IPv4 layer was found, the whole packet will be decoded looking for
 // it.
 ip4 := packet.Layer(layers.LayerTypeIPv4)
 // Decode all layers and return them.  The layers up to the first IPv4 layer
 // are already decoded, and will not require decoding a second time.
 layers := packet.Layers()

Lazily-decoded packets are not concurrency-safe.  Since layers have not all been
decoded, each call to Layer() or Layers() has the potential to mutate the packet
in order to decode the next layer.  If a packet is used
in multiple goroutines concurrently, don't use gopacket.Lazy.  Then gopacket
will decode the packet fully, and all future function calls won't mutate the
object.


NoCopy Decoding

By default, gopacket will copy the slice passed to NewPacket and store the
copy within the packet, so future mutations to the bytes underlying the slice
don't affect the packet and its layers.  If you can guarantee that the
underlying slice bytes won't be changed, you can use NoCopy to tell
gopacket.NewPacket, and it'll use the passed-in slice itself.

 // This channel returns new byte slices, each of which points to a new
 // memory location that's guaranteed immutable for the duration of the
 // packet.
 for data := range myByteSliceChannel {
   p := gopacket.NewPacket(data, layers.LayerTypeEthernet, gopacket.NoCopy)
   doSomethingWithPacket(p)
 }

The fastest method of decoding is to use both Lazy and NoCopy, but note from
the many caveats above that for some implementations either or both may be
dangerous.


Pointers To Known Layers

During decoding, certain layers are stored in the packet as well-known
layer types.  For example, IPv4 and IPv6 are both considered NetworkLayer
layers, while TCP and UDP are both TransportLayer layers.  We support 4
layers, corresponding to the 4 layers of the TCP/IP layering scheme (roughly
anagalous to layers 2, 3, 4, and 7 of the OSI model).  To access these,
you can use the packet.LinkLayer, packet.NetworkLayer,
packet.TransportLayer, and packet.ApplicationLayer functions.  Each of
these functions returns a corresponding interface
(gopacket.{Link,Network,Transport,Application}Layer).  The first three
provide methods for getting src/dst addresses for that particular layer,
while the final layer provides a Payload function to get payload data.
This is helpful, for example, to get payloads for all packets regardless
of their underlying data type:

 // Get packets from some source
 for packet := range someSource {
   if app := packet.ApplicationLayer(); app != nil {
     if strings.Contains(string(app.Payload()), "magic string") {
       fmt.Println("Found magic string in a packet!")
     }
   }
 }

A particularly useful layer is ErrorLayer, which is set whenever there's
an error parsing part of the packet.

 packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Default)
 if err := packet.ErrorLayer(); err != nil {
   fmt.Println("Error decoding some part of the packet:", err)
 }

Note that we don't return an error from NewPacket because we may have decoded
a number of layers successfully before running into our erroneous layer.  You
may still be able to get your Ethernet and IPv4 layers correctly, even if
your TCP layer is malformed.


Flow And Endpoint

gopacket has two useful objects, Flow and Endpoint, for communicating in a protocol
independent manner the fact that a packet is coming from A and going to B.
The general layer types LinkLayer, NetworkLayer, and TransportLayer all provide
methods for extracting their flow information, without worrying about the type
of the underlying Layer.

A Flow is a simple object made up of a set of two Endpoints, one source and one
destination.  It details the sender and receiver of the Layer of the Packet.

An Endpoint is a hashable representation of a source or destination.  For
example, for LayerTypeIPv4, an Endpoint contains the IP address bytes for a v4
IP packet.  A Flow can be broken into Endpoints, and Endpoints can be combined
into Flows:

 packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
 netFlow := packet.NetworkLayer().NetworkFlow()
 src, dst := netFlow.Endpoints()
 reverseFlow := gopacket.NewFlow(dst, src)

Both Endpoint and Flow objects can be used as map keys, and the equality
operator can compare them, so you can easily group together all packets
based on endpoint criteria:

 flows := map[gopacket.Endpoint]chan gopacket.Packet
 packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
 // Send all TCP packets to channels based on their destination port.
 if tcp := packet.Layer(layers.LayerTypeTCP); tcp != nil {
   flows[tcp.TransportFlow().Dst()] <- packet
 }
 // Look for all packets with the same source and destination network address
 if net := packet.NetworkLayer(); net != nil {
   src, dst := net.NetworkFlow().Endpoints()
   if src == dst {
     fmt.Println("Fishy packet has same network source and dst: %s", src)
   }
 }
 // Find all packets coming from UDP port 1000 to UDP port 500
 interestingFlow := gopacket.FlowFromEndpoints(layers.NewUDPPortEndpoint(1000), layers.NewUDPPortEndpoint(500))
 if t := packet.NetworkLayer(); t != nil && t.TransportFlow() == interestingFlow {
   fmt.Println("Found that UDP flow I was looking for!")
 }

For load-balancing purposes, both Flow and Endpoint have FastHash() functions,
which provide quick, non-cryptographic hashes of their contents.  Of particular
importance is the fact that Flow FastHash() is symmetric: A->B will have the same
hash as B->A.  An example usage could be:

 channels := [8]chan gopacket.Packet
 for i := 0; i < 8; i++ {
   channels[i] = make(chan gopacket.Packet)
   go packetHandler(channels[i])
 }
 for packet := range getPackets() {
   if net := packet.NetworkLayer(); net != nil {
     channels[int(net.NetworkFlow().FastHash()) & 0x7] <- packet
   }
 }

This allows us to split up a packet stream while still making sure that each
stream sees all packets for a flow (and its bidirectional opposite).


Implementing Your Own Decoder

If your network has some strange encapsulation, you can implement your own
decoder.  In this example, we handle Ethernet packets which are encapsulated
in a 4-byte header.

 // Create a layer type, should be unique and high, so it doesn't conflict,
 // giving it a name and a decoder to use.
 var MyLayerType = gopacket.RegisterLayerType(12345, gopacket.LayerTypeMetadata{Name: "MyLayerType", Decoder: gopacket.DecodeFunc(decodeMyLayer)})

 // Implement my layer
 type MyLayer struct {
   StrangeHeader []byte
   payload []byte
 }
 func (m MyLayer) LayerType() gopacket.LayerType { return MyLayerType }
 func (m MyLayer) LayerContents() []byte { return m.StrangeHeader }
 func (m MyLayer) LayerPayload() []byte { return m.payload }

 // Now implement a decoder... this one strips off the first 4 bytes of the
 // packet.
 func decodeMyLayer(data []byte, p gopacket.PacketBuilder) error {
   // Create my layer
   p.AddLayer(&MyLayer{data[:4], data[4:]})
   // Determine how to handle the rest of the packet
   return p.NextDecoder(layers.LayerTypeEthernet)
 }

 // Finally, decode your packets:
 p := gopacket.NewPacket(data, MyLayerType, gopacket.Lazy)

See the docs for Decoder and PacketBuilder for more details on how coding
decoders works, or look at RegisterLayerType and RegisterEndpointType to see how
to add layer/endpoint types to gopacket.


Fast Decoding With DecodingLayerParser

TLDR:  DecodingLayerParser takes about 10% of the time as NewPacket to decode
packet data, but only for known packet stacks.

Basic decoding using gopacket.NewPacket or PacketSource.Packets is somewhat slow
due to its need to allocate a new packet and every respective layer.  It's very
versatile and can handle all known layer types, but sometimes you really only
care about a specific set of layers regardless, so that versatility is wasted.

DecodingLayerParser avoids memory allocation altogether by decoding packet
layers directly into preallocated objects, which you can then reference to get
the packet's information.  A quick example:

 func main() {
   var eth layers.Ethernet
   var ip4 layers.IPv4
   var ip6 layers.IPv6
   var tcp layers.TCP
   parser := gopacket.NewDecodingLayerParser(layers.LayerTypeEthernet, ð, &ip4, &ip6, &tcp)
   decoded := []gopacket.LayerType{}
   for packetData := range somehowGetPacketData() {
     if err := parser.DecodeLayers(packetData, &decoded); err != nil {
       fmt.Fprintf(os.Stderr, "Could not decode layers: %v\n", err)
       continue
     }
     for _, layerType := range decoded {
       switch layerType {
         case layers.LayerTypeIPv6:
           fmt.Println("    IP6 ", ip6.SrcIP, ip6.DstIP)
         case layers.LayerTypeIPv4:
           fmt.Println("    IP4 ", ip4.SrcIP, ip4.DstIP)
       }
     }
   }
 }

The important thing to note here is that the parser is modifying the passed in
layers (eth, ip4, ip6, tcp) instead of allocating new ones, thus greatly
speeding up the decoding process.  It's even branching based on layer type...
it'll handle an (eth, ip4, tcp) or (eth, ip6, tcp) stack.  However, it won't
handle any other type... since no other decoders were passed in, an (eth, ip4,
udp) stack will stop decoding after ip4, and only pass back [LayerTypeEthernet,
LayerTypeIPv4] through the 'decoded' slice (along with an error saying it can't
decode a UDP packet).

Unfortunately, not all layers can be used by DecodingLayerParser... only those
implementing the DecodingLayer interface are usable.  Also, it's possible to
create DecodingLayers that are not themselves Layers... see
layers.IPv6ExtensionSkipper for an example of this.

Faster And Customized Decoding with DecodingLayerContainer

By default, DecodingLayerParser uses native map to store and search for a layer
to decode. Though being versatile, in some cases this solution may be not so
optimal. For example, if you have only few layers faster operations may be
provided by sparse array indexing or linear array scan.

To accomodate these scenarios, DecodingLayerContainer interface is introduced
along with its implementations: DecodingLayerSparse, DecodingLayerArray and
DecodingLayerMap. You can specify a container implementation to
DecodingLayerParser with SetDecodingLayerContainer method. Example:

 dlp := gopacket.NewDecodingLayerParser(LayerTypeEthernet)
 dlp.SetDecodingLayerContainer(gopacket.DecodingLayerSparse(nil))
 var eth layers.Ethernet
 dlp.AddDecodingLayer(ð)
 // ... add layers and use DecodingLayerParser as usual...

To skip one level of indirection (though sacrificing some capabilities) you may
also use DecodingLayerContainer as a decoding tool as it is. In this case you have to
handle unknown layer types and layer panics by yourself. Example:

 func main() {
   var eth layers.Ethernet
   var ip4 layers.IPv4
   var ip6 layers.IPv6
   var tcp layers.TCP
   dlc := gopacket.DecodingLayerContainer(gopacket.DecodingLayerArray(nil))
   dlc = dlc.Put(ð)
   dlc = dlc.Put(&ip4)
   dlc = dlc.Put(&ip6)
   dlc = dlc.Put(&tcp)
   // you may specify some meaningful DecodeFeedback
   decoder := dlc.LayersDecoder(LayerTypeEthernet, gopacket.NilDecodeFeedback)
   decoded := make([]gopacket.LayerType, 0, 20)
   for packetData := range somehowGetPacketData() {
     lt, err := decoder(packetData, &decoded)
     if err != nil {
       fmt.Fprintf(os.Stderr, "Could not decode layers: %v\n", err)
       continue
     }
     if lt != gopacket.LayerTypeZero {
       fmt.Fprintf(os.Stderr, "unknown layer type: %v\n", lt)
       continue
     }
     for _, layerType := range decoded {
       // examine decoded layertypes just as already shown above
     }
   }
 }

DecodingLayerSparse is the fastest but most effective when LayerType values
that layers in use can decode are not large because otherwise that would lead
to bigger memory footprint. DecodingLayerArray is very compact and primarily
usable if the number of decoding layers is not big (up to ~10-15, but please do
your own benchmarks). DecodingLayerMap is the most versatile one and used by
DecodingLayerParser by default. Please refer to tests and benchmarks in layers
subpackage to further examine usage examples and performance measurements.

You may also choose to implement your own DecodingLayerContainer if you want to
make use of your own internal packet decoding logic.

Creating Packet Data

As well as offering the ability to decode packet data, gopacket will allow you
to create packets from scratch, as well.  A number of gopacket layers implement
the SerializableLayer interface; these layers can be serialized to a []byte in
the following manner:

  ip := &layers.IPv4{
    SrcIP: net.IP{1, 2, 3, 4},
    DstIP: net.IP{5, 6, 7, 8},
    // etc...
  }
  buf := gopacket.NewSerializeBuffer()
  opts := gopacket.SerializeOptions{}  // See SerializeOptions for more details.
  err := ip.SerializeTo(buf, opts)
  if err != nil { panic(err) }
  fmt.Println(buf.Bytes())  // prints out a byte slice containing the serialized IPv4 layer.

SerializeTo PREPENDS the given layer onto the SerializeBuffer, and they treat
the current buffer's Bytes() slice as the payload of the serializing layer.
Therefore, you can serialize an entire packet by serializing a set of layers in
reverse order (Payload, then TCP, then IP, then Ethernet, for example).  The
SerializeBuffer's SerializeLayers function is a helper that does exactly that.

To generate a (empty and useless, because no fields are set)
Ethernet(IPv4(TCP(Payload))) packet, for example, you can run:

  buf := gopacket.NewSerializeBuffer()
  opts := gopacket.SerializeOptions{}
  gopacket.SerializeLayers(buf, opts,
    &layers.Ethernet{},
    &layers.IPv4{},
    &layers.TCP{},
    gopacket.Payload([]byte{1, 2, 3, 4}))
  packetData := buf.Bytes()

A Final Note

If you use gopacket, you'll almost definitely want to make sure gopacket/layers
is imported, since when imported it sets all the LayerType variables and fills
in a lot of interesting variables/maps (DecodersByLayerName, etc).  Therefore,
it's recommended that even if you don't use any layers functions directly, you still import with:

    _ "github.com/google/gopacket/layers"

/*
Package layers provides decoding layers for many common protocols.

The layers package contains decode implementations for a number of different
types of packet layers.  Users of gopacket will almost always want to also use
layers to actually decode packet data into useful pieces. To see the set of
protocols that gopacket/layers is currently able to decode,
look at the set of LayerTypes defined in the Variables sections. The
layers package also defines endpoints for many of the common packet layers
that have source/destination addresses associated with them, for example IPv4/6
(IPs) and TCP/UDP (ports).
Finally, layers contains a number of useful enumerations (IPProtocol,
EthernetType, LinkType, PPPType, etc...).  Many of these implement the
gopacket.Decoder interface, so they can be passed into gopacket as decoders.

Most common protocol layers are named using acronyms or other industry-common
names (IPv4, TCP, PPP).  Some of the less common ones have their names expanded
(CiscoDiscoveryProtocol).
For certain protocols, sub-parts of the protocol are split out into their own
layers (SCTP, for example).  This is done mostly in cases where portions of the
protocol may fulfill the capabilities of interesting layers (SCTPData implements
ApplicationLayer, while base SCTP implements TransportLayer), or possibly
because splitting a protocol into a few layers makes decoding easier.

This package is meant to be used with its parent,
http://github.com/google/gopacket.

Port Types

Instead of using raw uint16 or uint8 values for ports, we use a different port
type for every protocol, for example TCPPort and UDPPort.  This allows us to
override string behavior for each port, which we do by setting up port name
maps (TCPPortNames, UDPPortNames, etc...).  Well-known ports are annotated with
their protocol names, and their String function displays these names:

  p := TCPPort(80)
  fmt.Printf("Number: %d  String: %v", p, p)
  // Prints: "Number: 80  String: 80(http)"

Modifying Decode Behavior

layers links together decoding through its enumerations.  For example, after
decoding layer type Ethernet, it uses Ethernet.EthernetType as its next decoder.
All enumerations that act as decoders, like EthernetType, can be modified by
users depending on their preferences.  For example, if you have a spiffy new
IPv4 decoder that works way better than the one built into layers, you can do
this:

 var mySpiffyIPv4Decoder gopacket.Decoder = ...
 layers.EthernetTypeMetadata[EthernetTypeIPv4].DecodeWith = mySpiffyIPv4Decoder

This will make all future ethernet packets use your new decoder to decode IPv4
packets, instead of the built-in decoder used by gopacket.

//
// About The Network Time Protocol (NTP)
// -------------------------------------
// NTP is a protocol that enables computers on the internet to set their
// clocks to the correct time (or to a time that is acceptably close to the
// correct time). NTP runs on top of UDP.
//
// There have been a series of versions of the NTP protocol. The latest
// version is V4 and is specified in RFC 5905:
//     http://www.ietf.org/rfc/rfc5905.txt
//
//******************************************************************************

// Endian And Bit Numbering Issues

// Endian and bit numbering issues can be confusing. Here is some

//
//    ENDIAN: Values are sent big endian.
//    https://en.wikipedia.org/wiki/Endianness
//
//    BIT NUMBERING: Bits are numbered 0 upwards from the most significant
//    bit to the least significant bit. This means that if there is a 32-bit
//    value, the most significant bit is called bit 0 and the least
//    significant bit is called bit 31.

//
// NTP V3 and V4 Packet Format
// ---------------------------
// NTP packets are UDP packets whose payload contains an NTP record.
//
// The NTP RFC defines the format of the NTP record.
//
// There have been four versions of the protocol:
//
//    V1 in 1985
//    V2 in 1989
//    V3 in 1992
//    V4 in 2010
//
// It is clear that V1 and V2 are obsolete, and there is no need to
// cater for these formats.
//
// V3 and V4 essentially use the same format, with V4 adding some optional
// fields on the end. So this package supports the V3 and V4 formats.
//
// The current version of NTP (NTP V4)'s RFC (V4 - RFC 5905) contains
// the following diagram for the NTP record format:

//      0                   1                   2                   3

This layer decodes SFlow version 5 datagrams.

The specification can be found here: http://sflow.org/sflow_version_5.txt

Additional developer information about sflow can be found at:
http://sflow.org/developers/specifications.php

And SFlow in general:
http://sflow.org/index.php

Two forms of sample data are defined: compact and expanded. The
Specification has this to say:

    Compact and expand forms of counter and flow samples are defined.
    An agent must not mix compact/expanded encodings.  If an agent
    will never use ifIndex numbers >= 2^24 then it must use compact
    encodings for all interfaces.  Otherwise the expanded formats must
    be used for all interfaces.

This decoder only supports the compact form, because that is the only
one for which data was available.

The datagram is composed of one or more samples of type flow or counter,
and each sample is composed of one or more records describing the sample.
A sample is a single instance of sampled inforamtion, and each record in
the sample gives additional / supplimentary information about the sample.

The following sample record types are supported:

	Raw Packet Header

	Ethernet Interface Counters - see RFC 2358
	opaque = counter_data; enterprise = 0; format = 2

SFlow is encoded using XDR (RFC4506). There are a few places
where the standard 4-byte fields are partitioned into two
bitfields of different lengths. I'm not sure why the designers
chose to pack together two values like this in some places, and
in others they use the entire 4-byte value to store a number that
will never be more than a few bits. In any case, there are a couple
of types defined to handle the decoding of these bitfields, and
that's why they're there. */

/*
Package pcap allows users of gopacket to read packets off the wire or from
pcap files.

This package is meant to be used with its parent,
http://github.com/google/gopacket, although it can also be used independently
if you just want to get packet data from the wire.

Depending on libpcap version, os support, or file timestamp resolution,
nanosecond resolution is used for the internal timestamps. Returned timestamps
are always scaled to nanosecond resolution due to the usage of time.Time.
libpcap must be at least version 1.5 to support nanosecond timestamps. OpenLive
supports only microsecond resolution.

Reading PCAP Files

The following code can be used to read in data from a pcap file.

 if handle, err := pcap.OpenOffline("/path/to/my/file"); err != nil {
   panic(err)
 } else {
   packetSource := gopacket.NewPacketSource(handle, handle.LinkType())
   for packet := range packetSource.Packets() {
     handlePacket(packet)  // Do something with a packet here.
   }
 }

Reading Live Packets

The following code can be used to read in data from a live device, in this case
"eth0". Be aware, that OpenLive only supports microsecond resolution.

 if handle, err := pcap.OpenLive("eth0", 1600, true, pcap.BlockForever); err != nil {
   panic(err)
 } else if err := handle.SetBPFFilter("tcp and port 80"); err != nil {  // optional
   panic(err)
 } else {
   packetSource := gopacket.NewPacketSource(handle, handle.LinkType())
   for packet := range packetSource.Packets() {
     handlePacket(packet)  // Do something with a packet here.
   }
 }

Inactive Handles

Newer PCAP functionality requires the concept of an 'inactive' PCAP handle.
Instead of constantly adding new arguments to pcap_open_live, users now call
pcap_create to create a handle, set it up with a bunch of optional function
calls, then call pcap_activate to activate it.  This library mirrors that
mechanism, for those that want to expose/use these new features:

  inactive, err := pcap.NewInactiveHandle(deviceName)
  if err != nil {
    log.Fatal(err)
  }
  defer inactive.CleanUp()

  // Call various functions on inactive to set it up the way you'd like:
  if err = inactive.SetTimeout(time.Minute); err != nil {
    log.Fatal(err)
  } else if err = inactive.SetTimestampSource("foo"); err != nil {
    log.Fatal(err)
  }

  // Finally, create the actual handle by calling Activate:
  handle, err := inactive.Activate()  // after this, inactive is no longer valid
  if err != nil {
    log.Fatal(err)
  }
  defer handle.Close()

  // Now use your handle as you see fit.

PCAP Timeouts

pcap.OpenLive and pcap.SetTimeout both take timeouts.
If you don't care about timeouts, just pass in BlockForever,
which should do what you expect with minimal fuss.

A timeout of 0 is not recommended.  Some platforms, like Macs
(http://www.manpages.info/macosx/pcap.3.html) say:
  The read timeout is used to arrange that the read not necessarily return
  immediately when a packet is seen, but that it wait for some amount of time
  to allow more packets to arrive and to read multiple packets from the OS
  kernel in one operation.
This means that if you only capture one packet, the kernel might decide to wait
'timeout' for more packets to batch with it before returning.  A timeout of
0, then, means 'wait forever for more packets', which is... not good.

To get around this, we've introduced the following behavior:  if a negative
timeout is passed in, we set the positive timeout in the handle, then loop
internally in ReadPacketData/ZeroCopyReadPacketData when we see timeout
errors.

PCAP File Writing

This package does not implement PCAP file writing.  However, gopacket/pcapgo
does!  Look there if you'd like to write PCAP files.

Note For Windows Users

gopacket can use winpcap or npcap. If both are installed at the same time,
npcap is preferred. Make sure the right windows service is loaded (npcap for npcap
and npf for winpcap).

// This benchmark reads in file /gopacket_benchmark.pcap and measures
// the time it takes to decode all packets from that file.  If the file doesn't
// exist, it's pulled down from a publicly available location.  However, you can
// feel free to substitute your own file at that location, in which case the
// benchmark will run on your own data.
//
// It's also useful for figuring out which packets may be causing errors.  Pass
// in the --printErrors flag, and it'll print out error layers for each packet
// that has them.  This includes any packets that it's just unable to decode,
// which is a great way to find new protocols to decode, and get test packets to
// write tests for them.

Overview ▾

				

Package gopacket provides packet decoding for the Go language.




gopacket contains 3 sub-packages with additional functionality you may find
useful:



* layers: You'll probably use this every time.  This contains of the logic
    built into gopacket for decoding packet protocols.  Note that all example
    code below assumes that you have imported both gopacket and
    gopacket/layers.
* pcap: C bindings to use libpcap to pull packets off the wire.
* pfring: C bindings to use PF_RING to pull packets off the wire.



Basic Usage



gopacket takes in packet data as a []byte and decodes it into a packet with
a non-zero number of "layers".  Each layer corresponds to a protocol
within the bytes.  Once a packet has been decoded, the layers of the packet
can be requested from the packet.



// Decode a packet
packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Default)
// Get the TCP layer from this packet
if tcpLayer := packet.Layer(layers.LayerTypeTCP); tcpLayer != nil {
  fmt.Println("This is a TCP packet!")
  // Get actual TCP data from this layer
  tcp, _ := tcpLayer.(*layers.TCP)
  fmt.Printf("From src port %d to dst port %d\n", tcp.SrcPort, tcp.DstPort)
}
// Iterate over all layers, printing out each layer type
for layer := range packet.Layers() {
  fmt.Println("PACKET LAYER:", layer.LayerType())
}




Packets can be decoded from a number of starting points.  Many of our base
types implement Decoder, which allow us to decode packets for which
we don't have full data.



// Decode an ethernet packet
ethP := gopacket.NewPacket(p1, layers.LayerTypeEthernet, gopacket.Default)
// Decode an IPv6 header and everything it contains
ipP := gopacket.NewPacket(p2, layers.LayerTypeIPv6, gopacket.Default)
// Decode a TCP header and its payload
tcpP := gopacket.NewPacket(p3, layers.LayerTypeTCP, gopacketزP@@`?@
evJ#?
.Default)



Reading Packets From A Source



Most of the time, you won't just have a []byte of packet data lying around.
Instead, you'll want to read packets in from somewhere (file, interface, etc)
and process them.  To do that, you'll want to build a PacketSource.




First, you'll need to construct an object that implements the PacketDataSource
interface.  There are implementations of this interface bundled with gopacket
in the gopacket/pcap and gopacket/pfring subpackages... see their documentation
for more information on their usage.  Once you have a PacketDataSource, you can
pass it into NewPacketSource, along with a Decoder of your choice, to create
a PacketSource.




Once you have a PacketSource, you can read packets from it in multiple ways.
See the docs for PacketSource for more details.  The easiest method is the
Packets function, which returns a channel, then asynchronously writes new
packets into that channel, closing the channel if the packetSource hits an
end-of-file.



packetSource := ...  // construct using pcap or pfring
for packet := range packetSource.Packets() {
  handlePacket(packet)  // do something with each packet
}




You can change the decoding options of the packetSource by setting fields in
packetSource.DecodeOptions... see the following sections for more details.



Lazy Decoding



gopacket optionally decodes packet data lazily, meaning it
only decodes a packet layer when it needs to to handle a function call.



// Create a packet, but don't actually decode anything yet
packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
// Now, decode the packet up to the first IPv4 layer found but no further.
// If no IPv4 layer was found, the whole packet will be decoded looking for
// it.
ip4 := packet.Layer(layers.LayerTypeIPv4)
// Decode all layers and return them.  The layers up to the first IPv4 layer
// are already decoded, and will not require decoding a second time.
layers := packet.Layers()




Lazily-decoded packets are not concurrency-safe.  Since layers have not all been
decoded, each call to Layer() or Layers() has the potential to mutate the packet
in order to decode the next layer.  If a packet is used
in multiple goroutines concurrently, don't use gopacket.Lazy.  Then gopacket
will decode the packet fully, and all future function calls won't mutate the
object.



NoCopy Decoding



By default, gopacket will copy the slice passed to NewPacket and store the
copy within the packet, so future mutations to the bytes underlying the slice
don't affect the packet and its layers.  If you can guarantee that the
underlying slice bytes won't be changed, you can use NoCopy to tell
gopacket.NewPacket, and it'll use the passed-in slice itself.



// This channel returns new byte slices, each of which points to a new
// memory location that's guaranteed immutable for the duration of the
// packet.
for data := range myByteSliceChannel {
  p := gopacket.NewPacket(data, layers.LayerTypeEthernet, gopacket.NoCopy)
  doSomethingWithPacket(p)
}




The fastest method of decoding is to use both Lazy and NoCopy, but note from
the many caveats above that for some implementations they may be dangerous
either or both may be dangerous.



Pointers To Known Layers



During decoding, certain layers are stored in the packet as well-known
layer types.  For example, IPv4 and IPv6 are both considered NetworkLayer
layers, while TCP and UDP are both TransportLayer layers.  We support 4
layers, corresponding to the 4 layers of the TCP/IP layering scheme (roughly
anagalous to layers 2, 3, 4, and 7 of the OSI model).  To access these,
you can use the packet.LinkLayer, packet.NetworkLayer,
packet.TransportLayer, and packet.ApplicationLayer functions.  Each of
these functions returns a corresponding interface
(gopacket.{Link,Network,Transport,Application}Layer).  The first three
provide methods for getting src/dst addresses for that particular layer,
while the final layer provides a Payload function to get payload data.
This is helpful, for example, to get payloads for all packets regardless
of their underlying data type:



// Get packets from some source
for packet := range someSource {
  if app := packet.ApplicationLayer(); app != nil {
    if strings.Contains(string(app.Payload()), "magic string") {
      fmt.Println("Found magic string in a packet!")
    }
  }
}




A particularly useful layer is ErrorLayer, which is set whenever there's
an error parsing part of the packet.



packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Default)
if err := packet.ErrorLayer(); err != nil {
  fmt.Println("Error decoding some part of the packet:", err)
}




Note that we don't return an error from NewPacket because we may have decoded
a number of layers successfully before running into our erroneous layer.  You
may still be able to get your Ethernet and IPv4 layers correctly, even if
your TCP layer is malformed.



Flow And Endpoint



gopacket has two useful objects, Flow and Endpoint, for communicating in a protocol
independent manner the fact that a packet is coming from A and going to B.
The general layer types LinkLayer, NetworkLayer, and TransportLayer all provide
methods for extracting their flow information, without worrying about the type
of the underlying Layer.




A Flow is a simple object made up of a set of two Endpoints, one source and one
destination.  It details the sender and receiver of the Layer of the Packet.




An Endpoint is a hashable representation of a source or destination.  For
example, for LayerTypeIPv4, an Endpoint contains the IP address bytes for a v4
IP packet.  A Flow can be broken into Endpoints, and Endpoints can be combined
into Flows:



packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
netFlow := packet.NetworkLayer().NetworkFlow()
src, dst := netFlow.Endpoints()
reverseFlow := gopacket.NewFlow(dst, src)




Both Endpoint and Flow objects can be used as map keys, and the equality
operator can compare them, so you can easily group together all packets
based on endpoint criteria:



flows := map[gopacket.Endpoint]chan gopacket.Packet
packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
// Send all TCP packets to channels based on their destination port.
if tcp := packet.Layer(layers.LayerTypeTCP); tcp != nil {
  flows[tcp.TransportFlow().Dst()] <- packet
}
// Look for all packets with the same source and destination network address
if net := packet.NetworkLayer(); net != nil {
  src, dst := net.NetworkFlow().Endpoints()
  if src == dst {
    fmt.Println("Fishy packet has same network source and dst: %s", src)
  }
}
// Find all packets coming from UDP port 1000 to UDP port 500
interestingFlow := gopacket.NewFlow(layers.NewUDPPortEndpoint(1000), layers.NewUDPPortEndpoint(500))
if t := packet.NetworkLayer(); t != nil && t.TransportFlow() == interestingFlow {
  fmt.Println("Found that UDP flow I was looking for!")
}



Implementing Your Own Decoder



If your network has some strange encapsulation, you can implement your own
decoder.  In this example, we handle Ethernet packets which are encapsulated
in a 4-byte header.



// Create a layer type, should be unique and high, so it doesn't conflict,
// giving it a name and a decoder to use.
var MyLayerType = gopacket.RegisterLayerType(12345, "MyLayerType", gopacket.DecodeFunc(decodeMyLayer))

// Implement my layer
type MyLayer struct {
  StrangeHeader []byte
  payload []byte
}
func (m MyLayer) LayerType() LayerType { return MyLayerType }
func (m MyLayer) LayerContents() []byte { return m.StrangeHeader }
func (m MyLayer) LayerPayload() []byte { return m.payload }

// Now implement a decoder... this one strips off the first 4 bytes of the
// packet.
func decodeMyLayer(data []byte, p gopacket.PacketBuilder) error {
  // Create my layer
  p.AddLayer(&MyLayer{data[:4], data[4:]})
  // Determine how to handle the rest of the packet
  return p.NextDecoder(layers.LayerTypeEthernet)
}

// Finally, decode your packets:
p := gopacket.NewPacket(data, MyLayerType, gopacket.Lazy)




See the docs for Decoder and PacketBuilder for more details on how coding
decoders works, or look at RegisterLayerType and RegisterEndpointType to see how
to add layer/endpoint types to gopacket.

var ValidMACPrefixMap = validMACPrefixMap

				

ValidMACPrefixMap maps a valid MAC address prefix to the name of the
organization that owns the rights to use it.  We map it to a hidden
variable so it won't show up in godoc, since it's a very large map.



			
		
		
		
			
			
			
type ApplicationLayer

			
type ApplicationLayer interface {
    Layer
    Payload() []byte
}

			

ApplicationLayer is the packet layer corresponding to the TCP/IP layer 4 (OSI
layer 7), also known as the packet payload.




			

			

			

			

			
		
			
			
			
type CaptureInfo

			
type CaptureInfo struct {
    // Populated is set to true if the rest of the CaptureInfo has been populated
    // with actual information.  If Populated is false, there's no point in
    // reading any of the other fields.
    Populated             bool
    Timestamp             time.Time
    CaptureLength, Length int
}

			

CaptureInfo contains capture metadata for a packet.  If a packet was captured
off the wire or read from a pcap file (see the 'pcap' subdirectory), this
information will be attached to the packet.




			

			

			

			

			
		
			
			
			
type DecodeFailure

			
type DecodeFailure struct {
    // contains filtered or unexported fields
}

			

DecodeFailure is a packet layer created if decoding of the packet data failed
for some reason.  It implements ErrorLayer.  LayerContents will be the entire
set of bytes that failed to parse, and Error will return the reason parsing
failed.

func (*DecodeFailure) String

				
func (d *DecodeFailure) String() string

				
				
				
			
		
			
			
			
type DecodeFunc

			
type DecodeFunc func([]byte, PacketBuilder) error

			

DecodeFunc wraps a function to make it a Decoder.




			

			

			

			

			
				
				
func (DecodeFunc) Decode

				
func (d DecodeFunc) Decode(data []byte, p PacketBuilder) error

				
				
				
			
		
			
			
			
type DecodeOptions

			
type DecodeOptions struct {
    // Lazy decoding decodes the minimum number of layers needed to return data
    // for a packet at each function call.  Be careful using this with concurrent
    // packet processors, as each call to packet.* could mutate the packet, and
    // two concurrent function calls could interact poorly.
    Lazy bool
    // NoCopy decoding doesn't copy its input buffer into storage that's owned by
    // the packet.  If you can guarantee that the bytes underlying the slice
    // passed into NewPacket aren't going to be modified, this can be faster.  If
    // there's any chance that those bytes WILL be changed, this will invalidate
    // your packets.
    NoCopy bool
}

			

DecodeOptions tells gopacket how to decode a packet.




			

			
				
var Default DecodeOptions = DecodeOptions{}

				

Default decoding provides the safest (but slowest) method for decoding
packets.  It eagerly processes all layers (so it's concurrency-safe) and it
copies its input buffer upon creation of the packet (so the packet remains
valid if the underlying slice is modified.  Both of these take time,
though, so beware.  If you can guarantee that the packet will only be used
by one goroutine at a time, set Lazy decoding.  If you can guarantee that
the underlying slice won't change, set NoCopy decoding.



			
				
var Lazy DecodeOptions = DecodeOptions{Lazy: true}

				

Lazy is a DecodeOptions with just Lazy set.



			
				
var NoCopy DecodeOptions = DecodeOptions{NoCopy: true}

				

NoCopy is a DecodeOptions with just NoCopy set.



			

			

			

			
		
			
			
			
type Decoder

			
type Decoder interface {
    // Decode decodes the bytes of a packet, sending decoded values and other
    // information to PacketBuilder, and returning an error if unsuccessful.  See
    // the PacketBuilder documentation for more details.
    Decode([]byte, PacketBuilder) error
}

			

Decoder is an interface for logic to decode a packet layer.  Users may
implement a Decoder to handle their own strange packet types, or may use one
of the many decoders available in the 'layers' subpackage to decode things
for them.




			

			
				
var DecodePayload Decoder = DecodeFunc(decodePayload)

				

DecodePayload is a Decoder that returns a Payload layer containing all
remaining bytes.



			
				
var DecodeUnknown Decoder = DecodeFunc(decodeUnknown)

				

DecodeUnknown is a Decoder that returns a DecodeFailure layer containing all
remaining bytes, useful if you run up against a layer that you're unable to
decode yet.



			

			

			

			
		
			
			
			
type Endpoint

			
type Endpoint struct {
    // contains filtered or unexported fields
}

			

Endpoint is the set of bytes used to address packets at various layers.

func (e Endpoint) EndpointType() EndpointType

				

EndpointType returns the endpoint type associated with this endpoint.



				
				
			
				
				
func (Endpoint) LessThan

				
func (a Endpoint) LessThan(b Endpoint) bool

				

LessThan provides a stable ordering for all endpoints.  It sorts first based
on the EndpointType of an endpoint, then based on the raw bytes of that endpoint.
For some endpoints, the actual comparison may not make sense, however this
ordering does provide useful information for most Endpoint types.



				
				
			
				
				
func (Endpoint) Raw

				
func (e Endpoint) Raw() []byte

				

Raw returns the raw bytes of this endpoint.  These aren't human-readable
most of the time, but they are faster than calling String.



				
				
			
				
				
func (Endpoint) String

				
func (e Endpoint) String() string

				
				
				
			
		
			
			
			
type EndpointType

			
type EndpointType int64

the bytes stored in the endpoint should be interpreted.




			

			

			

			
				
				
func RegisterEndpointType

				
func RegisterEndpointType(num int, meta EndpointTypeMetadata) EndpointType

				

RegisterEndpointType creates a new EndpointType and registers it globally.
It MUST be passed a unique number, or it will panic.  Numbers 0-999 are
reserved for gopacket's use.



				
			

			
				
				
func (EndpointType) String

				
func (e EndpointType) String() string

				
				
				
			
		
			
			
			
type EndpointTypeMetadata

			
type EndpointTypeMetadata struct {
    // Name is the string returned by an EndpointType's String function.
    Name string
    // Formatter is called from an Endpoint's String function to format the raw
    // bytes in an Endpoint into a human-readable string.
    Formatter func([]byte) string

EndpointTypeMetadata is used to register a new endpoint type.




			

			

			

			

			
		
			
			
			
type ErrorLayer

			
type ErrorLayer interface {
    Layer
    Error() error
}

			

ErrorLayer is a packet layer created when decoding of the packet has failed.
Its payload is all the bytes that we were unable to decode, and the returned
error details why the decoding failed.




			

			

			

			

			
		
			
			
			
type Flow

			
type Flow struct {
    // contains filtered or unexported fields
}

			

Flow represents the direction of traffic for a packet layer, as a source and destination Endpoint.
Flows are usable as map keys.




			

			

			

			
				
				
func FlowFromEndpoints

				
func FlowFromEndpoints(src, dst Endpoint) (_ Flow, err error)

				

FlowFromEndpoints creates a new flow by pasting together two endpoints.
The endpoints must have the same EndpointType, or this function will return
an error.

"Src->Dst"



				
				
			
		
			
			
			
type Layer

			
type Layer interface {

    LayerType() LayerType
    // LayerContents returns the set of bytes that make up this layer.
    LayerContents() []byte
    // LayerPayload returns the set of bytes contained within this layer, not
    // including the layer itself.
    LayerPayload() []byte
}

			

Layer represents a single decoded packet layer (using either the
OSI or TCP/IP definition of a layer).  When decoding, a packet's data is
broken up into a number of layers.  The caller may call LayerType() to
figure out which type of layer he's received from the packet.  Optionally,
he may then use a type assertion to get the actual layer type for deep
inspection of the data.




			

			

			

			

			
		
			
			
			
type LayerClass

			
type LayerClass interface {
    // Contains returns true if the given layer type should be considered part
    // of this layer class.
    Contains(LayerType) bool
}

			

LayerClass is a set of LayerTypes, used for grabbing one of a number of
different types from a packet.




			

			

			

			
				
				
func NewLayerClass

				<زP@@`?@
e_J#?
pre>func NewLayerClassMap(types []LayerType) LayerClassMap

NewLayerClassMap creates a LayerClassMap and sets map[t] to true for each type in types.

func (LayerClassMap) Contains

func (m LayerClassMap) Contains(t LayerType) bool

Contains returns true if the given layer type should be considered part of this layer class.

type LayerClassSlice

type LayerClassSlice []bool

LayerClassSlice implements a LayerClass with a slice.

func NewLayerClassSlice

func NewLayerClassSlice(types []LayerType) LayerClassSlice

NewLayerClassSlice creates a new LayerClassSlice by creating a slice of size max(types) and setting slice[t] to true for each type t. Note, if you implement your own LayerType and give it a high value, this WILL create a very large slice.

func (LayerClassSlice) Contains

func (s LayerClassSlice) Contains(t LayerType) bool

Contains returns true if the given layer type should be considered part of this layer class.

type LayerType

type LayerType int64

LayerType is a unique identifier for each type of layer. This enumeration does not match with any externally available numbering scheme... it's solely usable/useful within this library as a means for requesting layer types (see Packet.Layer) and determining which types of layers have been decoded.

New LayerTypes may be created by calling gopacket.RegisterLayerType. 

var LayerTypeDecodeFailure LayerType = RegisterLayerType(0, LayerTypeMetadata{"Decode Failure", DecodeUnknown})

LayerTypeDecodeFailure is the layer type for the default error layer. 

var LayerTypePayload LayerType = RegisterLayerType(1, LayerTypeMetadata{"Payload", DecodePayload})

LayerTypePayload is the layer type for a payload that we don't try to decode but treat as a success, IE: an application-level payload.

func RegisterLayerType

func RegisterLayerType(num int, meta LayerTypeMetadata) LayerType

RegisterLayerType creates a new layer type and registers it globally. The number passed in must be unique, or a runtime panic will occur. Numbers 0-999 are reserved for the gopacket library. Numbers 1000-1999 should be used for common application-specific types, and are very fast. Any other number (negative or >= 2000) may be used for uncommon application-specific types, and are somewhat slower (they require a map lookup over an array index).

func (LayerType) Decode

func (t LayerType) Decode(data []byte, c PacketBuilder) error

Decode decodes the given data using the decoder registered with the layer type.

func (LayerType) String

func (t LayerType) String() (s string)

String returns the string associated with this layer type.

type LayerTypeMetadata

type LayerTypeMetadata struct {
    // Name is the string returned by each layer type's String method.
    Name string
    // Decoder is the decoder to use when the layer type is passed in as a
    // Decoder.
    Decoder Decoder
}

LayerTypeMetadata contains metadata associated with each LayerType.

type LinkLayer

    LinkFlow() Flow
}

LinkLayer is the packet layer corresponding to TCP/IP layer 1 (OSI layer 2)

type NetworkLayer

type NetworkLayer interface {
    Layer
    NetworkFlow() Flow
}

type Packet

type Packet interface {
    fmt.Stringer
    // Data returns all data associated with this packet
    Data() []byte
    // Layers returns all layers in this packet, computing them as necessary
    Layers() []Layer
    // Layer returns the first layer in this packet of the given type, or nil
    Layer(LayerType) Layer
    // LayerClass returns the first layer in this packet of the given class,
    // or nil.
    LayerClass(LayerClass) Layer
    // CaptureInfo returns the caputure information for this packet.  This returns
    // a pointer to the packet's struct, so it can be used both for reading and
    // writing the information.
    CaptureInfo() *CaptureInfo

    // LinkLayer returns the first link layer in the packet
    LinkLayer() LinkLayer
    // NetworkLayer returns the first network layer in the packet
    NetworkLayer() NetworkLayer
    // TransportLayer returns the first transport layer in the packet
    TransportLayer() TransportLayer
    // ApplicationLayer returns the first application layer in the packet
    ApplicationLayer() ApplicationLayer
    // ErrorLayer is particularly useful, since it returns nil if the packet
    // was fully decoded successfully, and non-nil if an error was encountered
    // in decoding and the packet was only partially decoded.  Thus, its output
    // can be used to determine if the entire packet was able to be decoded.
    ErrorLayer() ErrorLayer
}

Packet is the primary object used by gopacket. Packets are created by a Decoder's Decode call. A packet is made up of a set of Data, which is broken into a number of Layers as it is decoded.

func NewPacket

func NewPacket(data []byte, firstLayerDecoder Decoder, options DecodeOptions) Packet

NewPacket creates a new Packet object from a set of bytes. The firstLayerDecoder tells it how to interpret the first layer from the bytes, future layers will be generated from that first layer automatically.

type PacketBuilder

type PacketBuilder interface {
    // AddLayer should be called by a decoder immediately upon successful
    // decoding of a layer.
    AddLayer(l Layer)
    // The following functions set the various specific layers in the final
    // packet.  Note that if many layers call SetX, the first call is kept and all
    // other calls are ignored.
    SetLinkLayer(LinkLayer)
    SetNetworkLayer(NetworkLayer)
    SetTransportLayer(TransportLayer)
    SetApplicationLayer(ApplicationLayer)
    SetErrorLayer(ErrorLayer)
    // NextDecoder should be called by a decoder when they're done decoding a
    // packet layer but not done with decoding the entire packet.  The next
    // decoder will be called to decode the last AddLayer's LayerPayload.
    // Because of this, NextDecoder must only be called once all other
    // PacketBuilder calls have been made.  Set*Layer and AddLayer calls after
    // NextDecoder calls will behave incorrectly.
    NextDecoder(next Decoder) error
}

PacketBuilder is used by layer decoders to store the layers they've decoded, and to defer future decoding via NextDecoder. Typically, the pattern for use is: 

func (m *myDecoder) Decode(data []byte, p PacketBuilder) error {
  if myLayer, err := myDecodingLogic(data); err != nil {
    return err
  } else {
    p.AddLayer(myLayer)
  }
  // maybe do this, if myLayer is a LinkLayer
  p.SetLinkLayer(myLayer)
  return p.NextDecoder(nextDecoder)
}

type PacketDataSource

type PacketDataSource interface {
    // ReadPacketData returns the next packet available from this data source.
    // It returns:
    //  data:  The bytes of an individual packet.
    //  ci:  Metadata about the capture
    //  err:  An error encountered while reading packet data.  If err != nil,
    //    then data/ci will be ignored.
    ReadPacketData() (data []byte, ci CaptureInfo, err error)
}

PacketDataSource is an interface for some source of packet data. Users may create their own implementations, or use the existing implementations in gopacket/pcap (libpcap, allows reading from live interfaces or from pcap files) or gopacket/pfring (PF_RING, allows reading from live interfaces).

type PacketSource

type PacketSource struct {

    // DecodeOptions is the set of options to use for decoding each piece
    // of packet data.  This can/should be changed by the user to reflect the
    // way packets should be decoded.
    DecodeOptions
    // contains filtered or unexported fields
}

PacketSource reads in packets from a PacketDataSource, decodes them, and returns them.

There are currently two different methods for reading packets in through a PacketSource:

Reading With Packets Function

This method is the most convenient and easiest to code, but lacks flexibility. Packets returns a 'chan Packet', then asynchronously writes packets into that channel. Packets uses a blocking channel, and closes it if an io.EOF is returned by the underlying PacketDataSource. All other PacketDataSource errors are ignored and discarded. 

for packet := range packetSource.Packets() {
  ...
}

Reading With NextPacket Function

This method is the most flexible, and exposes errors that may be encountered by the underlying PacketDataSource. It's also the fastest in a tight loop, since it doesn't have the overhead of a channel read/write. However, it requires the user to handle errors, most importantly the io.EOF error in cases where packets are being read from a file. 

for {
  packet, err := packetSource.NextPacket() {
  if err == io.EOF {
    break
  } else if err != nil {
    log.Println("Error:", err)
    continue
  }
  handlePacket(packet)  // Do something with each packet.
}

func NewPacketSource

func NewPacketSource(source PacketDataSource, decoder Decoder) *PacketSource

NewPacketSource creates a packet data source.

func (*PacketSource) NextPacket

func (p *PacketSource) NextPacket() (Packet, error)

NextPacket returns the next decoded packet from the PacketSource. On error, it returns a nil packet and a non-nil error.

func (*PacketSource) Packets

func (p *PacketSource) Packets() chan Packet

Packets returns a blocking channel of packets, allowing easy iterating over packets. Packets will be asynchronously read in from the underlying PacketDataSource and written to the returned channel. If the underlying PacketDataSource returns an io.EOF error, the channel will be closed. If any other error is encountered, it is ignored. 

for packet := range packetSource.Packets() {
  handlePacket(packet)  // Do something with each packet.
}

type Payload

type Payload struct {
    Data []byte
}

Payload is a Layer containing the payload of a packet. The definition of what constitutes the payload of a packet depends on previous layers; for TCP and UDP, we stop decoding above layer 4 and return the remaining bytes as a Payload. Payload is an ApplicationLayer.

func (*Payload) LayerContents

func (p *Payload) LayerContents() []byte

func (*Payload) LayerPayload

func (p *Payload) LayerPayload() []byte

func (*Payload) LayerType

func (p *Payload) LayerType() LayerType

LayerType returns LayerTypePayload

func (*Payload) Payload

func (p *Payload) Payload() []byte

func (*Payload) String

func (p *Payload) String() string

type TransportLayer

type TransportLayer interface {
    Layer
    TransportFlow() Flow
}

TransportLayer is the packet layer corresponding to the TCP/IP layer 3 (OSI layer 4)

PF_RING is a high-performance packet capture library written by ntop.org (see http://www.ntop.org/products/pf_ring/). This library allows you to utilize the PF_RING library with gopacket to read packet data and decode it. This package is meant to be used with its parent, http://github.com/google/gopacket, although it can also be used independently if you just want to get packet data from the wire. Simple Example This is probably the simplest code you can use to start getting packets through pfring: if ring, err := pfring.NewRing("eth0", 65536, pfring.FlagPromisc); err != nil { panic(err) } else if err := ring.SetBPFFilter("tcp and port 80"); err != nil { // optional panic(err) } else if err := ring.Enable(); err != nil { // Must do this!, or you get no packets! panic(err) } else { packetSource := gopacket.NewPacketSource(ring, layers.LinkTypeEthernet) for packet := range packetSource.Packets() { handlePacket(packet) // Do something with a packet here. } } Pfring Tweaks PF_RING has a ton of optimizations and tweaks to make sure you get just the packets you want. For example, if you're only using pfring to read packets, consider running: ring.SetSocketMode(pfring.ReadOnly) If you only care about packets received on your interface (not those transmitted by the interface), you can run: ring.SetDirection(pfring.ReceiveOnly) Pfring Clusters PF_RING has an idea of 'clusters', where multiple applications can all read from the same cluster, and PF_RING will multiplex packets over that cluster such that only one application receives each packet. We won't discuss this mechanism in too much more detail (see the ntop.org docs for more info), but here's how to utilize this with the pfring go library: ring.SetCluster(1, pfring.ClusterPerFlow5Tuple) */ package pfring gopacket-1.1.19/pfring/pfring.go000066400000000000000000000327201374333536000165140ustar00rootroot00000000000000// Copyright 2012 Google, Inc.

Assemblers // lock the StreamPool when looking up connections, but they use Reader // locks initially, and only force a write lock if they need to create a new // connection or close one down. These happen much less frequently than // individual packet handling. // // Each assembler runs in its own goroutine, and the only state shared between // goroutines is through the StreamPool. Thus all internal Assembler state // can be handled without any locking. // // NOTE: If you can guarantee that packets going to a set of Assemblers will // contain information on different connections per Assembler (for example, // they're already hashed by PF_RING hashing or some other hashing mechanism), // then we recommend you use a seperate StreamPool per Assembler, thus // avoiding all lock contention. Only when different Assemblers could receive // packets for the same Stream should a StreamPool be shared between them. // // Avoids Memory Copying // // In the common case, handling of a single TCP packet should result in zero // memory allocations. The Assembler will look up the connection, figure out // that the packet has arrived in order, and immediately pass that packet on to // the appropriate connection's handling code. Only if a packet arrives out of // order is its contents copied and stored in memory for later. // // Avoids Memory Allocation // // Assemblers try very hard to not use memory allocation unless absolutely // necessary. Packet data for sequential packets is passed directly to streams // with no copying or allocation. Packet data for out-of-order packets is // copied into reusable pages, and new pages are only allocated rarely when the // page cache runs out.

Assemblers // lock the StreamPool when looking up connections, but they use Reader // locks initially, and only force a write lock if they need to create a new // connection or close one down. These happen much less frequently than // individual packet handling. // // Each assembler runs in its own goroutine, and the only state shared between // goroutines is through the StreamPool. Thus all internal Assembler state // can be handled without any locking. // // NOTE: If you can guarantee that packets going to a set of Assemblers will // contain information on different connections per Assembler (for example, // they're already hashed by PF_RING hashing or some other hashing mechanism), // then we recommend you use a seperate StreamPool per Assembler, thus // avoiding all lock contention. Only when different Assemblers could receive // packets for the same Stream should a StreamPool be shared between them. // // Avoids Memory Copying // // In the common case, handling of a single TCP packet should result in zero // memory allocations. The Assembler will look up the connection, figure out // that the packet has arrived in order, and immediately pass that packet on to // the appropriate connection's handling code. Only if a packet arrives out of // order is its contents copied and stored in memory for later. // // Avoids Memory Allocation // // Assemblers try very hard to not use memory allocation unless absolutely // necessary.
