+Contributing To gopacket
+========================
+
+So you've got some code and you'd like it to be part of gopacket... wonderful!
+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 <mynewfeature> # 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.

+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:

+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
+// clarification:
+//
+// 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
+// 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

+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
+ opaque = flow_data; enterprise = 0; format = 1
+
+ Extended Switch Data
+ opaque = flow_data; enterprise = 0; format = 1001
+
+ Extended Router Data
+ opaque = flow_data; enterprise = 0; format = 1002
+
+ Extended Gateway Data
+ opaque = flow_data; enterprise = 0; format = 1003
+
+ Extended User Data
+ opaque = flow_data; enterprise = 0; format = 1004
+
+ Extended URL Data
+ opaque = flow_data; enterprise = 0; format = 1005
+
+The following types of counter records are supported:
+
+ Generic Interface Counters - see RFC 2233
+ opaque = counter_data; enterprise = 0; format = 1
+
+ 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. */

+# uuid 
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services.
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid). It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice. One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).
+
+###### Install
+`go get github.com/google/uuid`
+
+###### Documentation
+[](http://godoc.org/github.com/google/uuid)
+
+Full `go doc` style documentation for the package can be viewed online without
+installing this package by using the GoDoc site here:
+http://pkg.go.dev/github.com/google/uuid
