From 73dd8af4c99b528b2d9f9bb59339084efa30c0c3 Mon Sep 17 00:00:00 2001 From: Winlin Date: Wed, 2 Aug 2023 22:49:49 +0800 Subject: [PATCH] HLS: Ignore empty NALU to avoid error. v6.0.65 (#3750) For the DJI M30, there is a bug where empty NALU packets with a size of zero are causing issues with HLS streaming. This bug leads to random unpublish events due to the SRS disconnecting the connection for the HLS module when it fails to handle empty NALU packets. To address this bug, we have patched the system to ignore any empty NALU packets with a size of zero. Additionally, we have created a tool in the srs-bench to replay pcapng files captured by tcpdump or Wireshark. We have also added utest using mprotect and asan to detect any memory corruption. It is important to note that this bug has been fixed in versions 4.0.271 6477f31004c7c5ff95715b9b3f3afc798e81704d and 5.0.170 939f6b484b34c7e1f73217ab79948fbd0b439dfa. This patch specifically addresses the issue in SRS 6.0. Please be aware that there is another commit related to this bug that partially fixes the issue but still leaves a small problem for asan to detect memory corruption. This commit, 577cd299e1792cbc063b72a582688c2e2977bf22, only ignores empty NALU packets but still reads beyond the memory. --------- Co-authored-by: chundonglinlin --- .github/workflows/release.yml | 3

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.

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. diff --git a/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/LICENSE b/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/LICENSE new file mode 100644 index 000000000..2100d524d --- /dev/null +++ b/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/LICENSE @@ -0,0 +1,28 @@ +Copyright (c) 2012 Google, Inc.

Each layer corresponds to a protocol +within the bytes.

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: + + import ( + _ "github.com/google/gopacket/layers" + ) +*/ +package gopacket diff --git a/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/flows.go b/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/flows.go new file mode 100644 index 000000000..a00c88398 --- /dev/null +++ b/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/flows.go @@ -0,0 +1,236 @@ +// Copyright 2012 Google, Inc.

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. +*/ +package layers diff --git a/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/layers/dot11.go b/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/layers/dot11.go new file mode 100644 index 000000000..3e6491061 --- /dev/null +++ b/trunk/3rdparty/srs-bench/vendor/github.com/google/gopacket/layers/dot11.go @@ -0,0 +1,2118 @@ +// Copyright 2014 Google, Inc.
