||
| ==Overview== | ||
|
|
||
| This changelog is meant to provide a history of the high (and low) points of the | ||
| gopacket library. We won't put things into it for every change that's | ||
| submitted, but it will hightlight some of the particulary interesting or | ||
| largescale changes made along the way. Also, importantly, every change which | ||
| could cause backwards incompatibility will be documented here. | ||
|
|
||
| If you're adding a change here, please use the already-established style for | ||
| doing so. Major changes or additions should also be announced at the | ||
| gopacket@googlegroups.com mailing list. | ||
|

|
||
| ===v1.0.5 20140121 Fix pcap/pfring timestamps.=== | ||
|
|
||
| We were incorrectly treating timestamps coming from pfring and pcap as nanoseconds, when they were in fact microseconds. Thanks to Peter Membrey for pointing this out. | ||
|
|
||
| ===v1.0.4 20131220 SYN scanning example, simple routing table.=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=181aef30c2f5c0488c81cdfbab97fed70e7625ab | ||
|
|
||
| Added a SYN scanner. Due to needing to send data off the local network, I also had to do | ||
| some routing, so I created a very simplistic router using the routing table provided by | ||
| netlink. This router is very untested so far, but it should allow simple network | ||
| utilities to send packets pretty easily. | ||
|
|
||
| ===v1.0.3 20131220 Write/Fix/Move example code=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=26e14693245d21d9dfb69381803f373a44dcbab6 | ||
|
|
||
| Wrote arp scanning example to show basic packet generation and sending. Fixed tcp assembly | ||
| example to not hang forever. Moved all example binaries into examples subdirectory. | ||
|
|
||
| ===v1.0.2 20131202 Serialization bugfixes for IPv4/TCP=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=e28112142a483f757bbc2c13e22cbbd7bd29fa13 | ||
|
|
||
| Fixes FixLengths in gopacket to correctly set tcp.DataOffset and ip4.IHL. | ||
|
|
||
| ===v1.0.1 20131004 More serialization, MPLS bugfix=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=96888560c968dd5b5b3b1e2212147792e25769bf | ||
|
|
||
| Adds serialization for ARP, EAP, ICMPv4, ICMPv6, MPLS, PPP, and PPPoE. | ||
| Fixes bug in MPLS where wrong bit was being used for bottom-of-stack. | ||
|
|
||
| ===v1.0.0 20131004 Semantic Versioning=== | ||
|
|
||
| Added semantic versioning (http://semver.org/) to gopacket, for easier go | ||
| dependency management. Starting at v1.0.0 since the current API is | ||
| relatively stable and usable, and I don't want anyone scared away by | ||
| a v0 version number. | ||
|
|
||
| ===20131003 Packet serialization.=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=63984d308e5f90225599c32dffd885c5c3d49aba | ||
|
|
||
| Adds the ability to create packet data from layer structs. | ||
|
|
||
| ===20130930 Add DecodingLayer implementation to numerous layers=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=c3135e34b82b6439303aa44b0f92d047f877fb70 | ||
|
|
||
| Add DecodingLayer capabilities to ARP, Dot1Q, EAP, EAPOL, EtherIP, GRE, ICMPv6, | ||
| and IGMP. | ||
|
|
||
| ===20130930 zero-copy capabilities for *pcap*=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=18af9281fcf4d396d4fe3767ad1413f28c242d9e | ||
|
|
||
| Adds the ability to use *pcap* subpackage without copying packet data from C to | ||
| Go, saving a full copy of all data. Benchmarks against live traffic have shown | ||
| a 2x increase in the throughput processable by a single core. | ||
|
|
||
| ===20130917 IGMP support=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=1c9fcb5b211d2b721ace744a410103c4eef69233 | ||
|
|
||
| ===20130821 AF_PACKET support=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=3a810335f15ad55ba4b6cdf76181c5bbbade5df3 | ||
|
|
||
| ===20130722 BACKWARDS INCOMPATIBLE Moved valid mac prefixes into subpackage=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=27312f15fcf8cd261a3bd576263ec587d4a19a20 | ||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=43cd11eec5c6f690e73420d534e3605c2076f7d7 | ||
|
|
||
| In order to speed up compiles, the map of valid MAC addresses was moved into a | ||
| subpackage. | ||
|
|
||
| Adds support for linux AF_PACKET into the *afpacket* subpackage. | ||
|
|
||
| ===20130711 Fix build breakage on Windows=== | ||
|
|
||

|
|
||
| ===20130618 TCP Reassembly=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=119d4fcbfd8aa12f449ac44ec3e54c92b0ede64b | ||
|
|
||
| Added the *tcpassembly* subpackage to quickly reassemble TCP streams for | ||
| sniffing applications. Along with reassembling streams, this new subpackage | ||
| also has some logic to provide those streams as an io.Reader interface, allowing | ||
| callers to make use of existing standard library implementations (net/http) for | ||
| stream processing. | ||
|
|
||
| ===20130611 Decoding Known Packet Stacks=== | ||
|
|
||
| Commit: | ||
| https://code.google.com/p/gopacket/source/detail?r=1688462e35ceda1b5914434bd1add89190c0526e | ||
|
|
||
| Allowed users to decode a known layer stack from packet data with zero | ||
| memory allocations, creating a much faster packet processing framework. | ||
| 10x speed up for simple packet stacks (eth/ip/tcp/payload). | ||
|
|
||
| ===20130522 Lots of work on LLDP, NortelDiscovery, and CDP contributed by | ||
| bdaglish@restorepoint.com=== | ||
|
|
||
| Lots of commits for this one, but everything was fully committed as of | ||
| https://code.google.com/p/gopacket/source/detail?r=45d548af72767a6401fa3f928704c236461fffcd | ||
