(Thomas Habets) + - Use SO_BINDTODEVICE to force packets out opened device. (someone) + - Always use an IPPROTO of TCP when calculating TCP checksums. (Sam Roberts) + - Use correct addr type for addrlen calculation. (someone) + - libnet_build_igmp reserved field was mistakenly called 'code' (Sam Roberts) + - Documentation doesn't include any gif files. (Sam Roberts) + - Enable IPV6 support on Solaris 11. (Rich Burridge) + - Trying to fix write errors (ViÌctor MartiÌnez) + - Presence of linux's PF_PACKET sockets is now detected. The acinclude.m4 merged in from packetfactory's 1.1.3-rc branch mysteriously assumed that that there was no PF_PACKET if the target OS was linux, which is the opposite of what we want. (Sam Roberts) + - Fix libnet_build_igmp() to not reverse the order of the ip address. libnet APIs that take IP addresses as a uint32_t expect them to already be in network byte order. (Sam Roberts) + - pblock_append deals with raw memory and structs, so declare it correctly (Sam Roberts) + - Clarified types and sizes of DHCP/BOOTP chaddr, sname, and file. chaddr is a hardware address, with size specified seperately, whereas sname and file are null terminated strings. (Sam Roberts) + - Explicitly ignore return value of write (some systems now warn about this). (Sam Roberts) + - Synchronize comment about h_len with parameter name in function. (Sam Roberts) + - Fixes a buffer overflow issue when copying chaddr, file, and sname fields to the DHCP header. (allfro) + - Fixes improper calculation of header size when libnet_pblock_probe is called. payload_s must be added to the header length in order to accommodate for the existence of a non-NULL payload. Otherwise the user is prompted with a 'memcpy would cause overflow' error and the program exits. (allfro) + - Fixes incorrect memory block size set in the timeexceed and redirect builders. The n variable does not add the size of the payload (payload_s) for proper allocation of the buffer when payload is not NULL and payload_s is greater than 0. This results in a memcpy buffer overflow error when libnet_pblock_append is called exiting the program. (allfro) + - Fixes a bug that incorrectly converts the addr, mask, and next_hop fields to network byte order. Users will usually call libnet_name2addr4 to fill these fields and this function already provides a network byte-ordered value. (allfro) + - snap parameter was getting copied into the dhost field. (Sam Roberts) + - h_len is no longer used, so pass zero. Coverity noticed that stack garbage was being passed instead of a valid value, its just that the value isn't used, and incluing l->total_size is wrong when the pblock is being updated (though it will work on pblock creation). (Sam Roberts) + - Length n should include the value_hdr. (Sam Roberts) + - Coverity: UNINIT (Jiri Popelka) + - Coverity: REVERSE_INULL (Jiri Popelka) + - Coverity: RESOURCE_LEAK (Jiri Popelka) + - Coverity: OVERRUN_STATIC (Jiri Popelka) + - Coverity: OVERRUN_STATIC (Jiri Popelka) + - Coverity: OVERRUN_STATIC (Jiri Popelka) + - Coverity: FORWARD_NULL (Jiri Popelka) + - Coverity: FORWARD_NULL (Jiri Popelka) + - Coverity: CHECKED_RETURN (Jiri Popelka) + - mkinstalldirs is replaced by autogen.sh. Maybe it shouldn't be checked in? (Sam Roberts) + - autogen retries if /sw/... doesn't exist (Sam Roberts) + - build_ipv6: set higher traffic class bits (Ulrich Weber) + - Fix missing uint instead of u_int (Dagobert Michelsen) + +- 1.1.5 + + - IRIX: Get MAC address from ioctl(), not by spawning shell. (Thomas Habets) + - Compile fix for IRIX (added includes) (Thomas Habets) + - Don't explicitly check for UID 0, we may have capabilities even if not root. (Thomas Habets) (Sam Roberts) + - Cleaned up implementations of libnet_get_hwaddr(), some leaked memory, one returned a pointer to data on the stack, and the others return a pointer to static data. I'm settling on the non-reentrant static data form. (Sam Roberts) + - Visual C++ compiler(v9.0) uses bitfield type as a hint to pad the bitfield, so struct was too long. (Sam Roberts) + - Further simplify autogen.sh (Sam Roberts) + - Removed dependency on net/bpf.h, and on pcap.h. (Sam Roberts) + - LBL_ALIGN check is unused, removing. (Sam Roberts) + - Don't include pcap.h if we've already got net/bpf.h, pcap has it's own bpf. (Sam Roberts) + - Make libnet_get_hwaddr work in the last few releases of OpenBSD (stu@spacehopper.org) (Sam Roberts) + - Get DLT types from the source, <pcap.h>. (Sam Roberts) + - Use autoconf -ivf in autogen.sh (suggested by alon.barlev@gmail.com) (Sam Roberts) + - Don't distribute libnet.h, it is generated by configure (alon.barlev@gmail.com) (Sam Roberts) + - AIX build failures fixed, cause was inclusion of system headers libnet no longer uses (alon.barlev@gmail.com) (Sam Roberts) + - Add a link to the old docs. (Sam Roberts) + - Added links to github and sourceforge. (Sam Roberts) + - Replace C99/C++ comments with traditional C comments. (alon.barlev@gmail.com) (Sam Roberts) + - checksum would segfault if a IP checksum was requested for a non-ipv4 header (Sam Roberts) + - Closer backwards compat, assume its ipv4 if it's not ipv6. This seems totally wrong, but so it goes. (Sam Roberts) + - Try using the ip_len header field to guess the input buffer's size. (Sam Roberts) + - libnet_do_checksum(), despite being "internal", is used by external code. libnet needs to maintain backwards API compatibility, tcpsic from the isic package is an example of a binary failing when calling the new API with the old arguments. (Sam Roberts) + - merged icmpv6 patch in, but I believe either it or the sample/icmp6_unreach generates the cksum incorrectly (victor@inliniac.net) (Sam Roberts) + - Use libtool-1 or libtool-2 whatever available (alon.barlev@gmail.com) (Sam Roberts) + - Avoid looking at /dev and /usr/include when cross-compiling (alon.barlev@gmail.com) Alon: The following code support cross compiling: 1. You CANNOT check for /usr/include stuff as cross compiler is installed else-where. Autoconf know how to do this, use its header detection logic and ask the result. 2. Testing for /dev/ can be done only when not cross compiling... (Sam Roberts) + - Corrected target_os check, it was broke for linuxgnu, and m4 syntax was invalid (alon.barlev@gmail.com) Alon:The following change is needed in order to solve two issues: 1. linuxgnu and such target os. 2. You cannot set variable with space before '=' as it tries to execute the variable... 3. Print result of test in case of linux (Sam Roberts) + - --with-link-layer broken, was using wrong macro name, and didn't include all link types (Sam Roberts) + - ac_cv_c_bigendian is yes, not "big" (alon.barlev@gmail.com) (Sam Roberts) + - Remove dead code. (Sam Roberts) + - h_len is calculated for ip, udp, tcp, icmp, and igmp, so is allowed to be zero. (Sam Roberts) + - libnet_t's fd should be initialized to an invalid value, or libnet_destroy() will close stdin. (Sam Roberts) + - Alon's use of AC_CHECK_HEADERS fails to detect headers. Reverted part of 57acd56f09158decb69f301e7547ce8cde6ac63f (Sam Roberts) + - With link_none, the link apis were failing with not error message. (Sam Roberts) + - man doc makefile wasn't correctly referring to the srcdir (alon.barlev@gmail.com) (Sam Roberts) + - Avoid mallocing zero bytes, it perturbs electric fence. (Sam Roberts) + - autotools patches for cross compiling and seperate builddir (alon.barlev@gmail.com) (Sam Roberts) + - html doc makefile wasn't correctly referring to the srcdir (alon.barlev@gmail.com) (Sam Roberts) + - ip_offset is now calculated on the fly, and UDP and TCP no longer use h_len (Sam Roberts) + - IP offset calculation should allow nesting of IP protocols. (Sam Roberts) + - Remove gccisms in bitfield definitions. (Sam Roberts) + - injection type of LIBNET_NONE, for packet construction without injection (also, more const correctness) (Sam Roberts) + - Notes about checksumming. (Sam Roberts) + - libnet_build_tcp was not returning the ptag. (Sam Roberts) + - Packet boundaries are now passed to _do_checksum(), so it can validate its input. Hopefully, this will end the recurring segmentation faults due to buffer overruns. (Sam Roberts) + - TCP building is triggering memory overwrites; closer examination shows the link list manipulation to be wrong, and the checksumming approach to be incapable of working. I reworked code to simplify and clarify how it works currently, in preparation to fixing it. (Sam Roberts) + - Updated comments and notes. (Sam Roberts) + - Null the pointer in the about-to-be-freed structure, not the one on the stack. (Sam Roberts) + - Added missing pblock types, and made strings consistent with definitions. (Sam Roberts) + - Change version policy, we will be 1.1.4 until 1.1.5 is released. (Sam Roberts) + - Bring CHANGELOG up to date with today, and script used to generated it. (Sam Roberts) + - Begin implementation and tests for repairing pblocks after an update. (Sam Roberts) + - libnet_pblock_insert_before() didn't remove ptag2 from old location (Sam Roberts) + - Clarifications in document comments. (Sam Roberts) + - Don't doxygen process internal header libnet-headers.h (Sam Roberts) + - Declared many constant arguments as const, const-correct code spews warnings when built against libnet. (Sam Roberts) + - Include pcap DLT_ types from correct header, was using an internal one before. (Sam Roberts) + - Declared many constant arguments as const, const-correct code spews warnings when built against libnet. (Sam Roberts) + - Note about build_data, which doesn't update ip_offset, among other problems. (Sam Roberts) + - libnet_clear_packet() wasn't clearing all packet context. (Sam Roberts) + - Why don't TCP and UDP use the DATA pblock type? (Sam Roberts) + - whitespace cleanup (Sam Roberts) + - Add libnet_dll.c as extra, so its there for win32, and build libnet_link.c (Sam Roberts) + - This file wasn't being built, and needed to include bpf to build. (Sam Roberts) + - Forgot to make device a const string here, too. (Sam Roberts) + - make string argument constant (Sam Roberts) + - only ignore Makefile in libnet/ (Sam Roberts) + - Replace u_intX_t with C99 uintX_t.

Schiffman <mike@infonexus.com> + http://www.packetfactory.net/libnet +=============================================================================== + + + DESIGN NOTES + + In order to remove most of the decisions a user had to make (how much + memory to allocate for a packet, where to build the packet headers, where + to do the checksums, how to inject the packet, etc) I decided to move ALL + of that logic into the library, behind the scenes. To initialize + things and get an initial libnet context, the applications programmer + calls: + + libnet_t *l; + l = libnet_init(INJECTION_TYPE, PROTOCOL, DEVICE, ERRBUFFER); + + where: + + INJECTION_TYPE = LIBNET_RAW4 (ipv4 raw socket) + LIBNET_RAW6 (ipv6 raw socket) + LIBNET_LINK (link-layer socket) + LIBNET_RAW4_ADV (advanced mode) + LIBNET_RAW6_ADV (advanced mode) + LIBNET_LINK_ADV (advanced mode) + + PROTOCOL = IP protocol to be used for the raw socket. This is + ignored for the link-layer, and almost always + IPPROTO_RAW for ipv4. + + DEVICE = The canoical name of the device, used only with the link + layer stuff. For ipv4 raw socket, you can leave this + NULL. If it's NULL with the link-layer, libnet will try + to find a suitable device. + + ERRBUFFER = Until we have our libnet context l, this is where + errors will be. + + Inside of this newly created context we have a ton of stuff including a + file descriptor for the packet device the injection type, the device name + (if applicable) a pointer to the libnet protocol block structure and some + other ancillary data. + + Additionally, we will soon be supporting context manipulation functions + that will allow the user to set certain flags inside the context. This + interface will be akin to libnet_toggle_checksum() for those of you who + care. + + When a packet is first constructed, the protocol block (pblock) stuff comes + into play. On the outside, to an applications programmer, a packet is + constructed more or less like normal (with a few notable exceptions): + + libnet_ptag_t ip_tag; + ip_tag = libnet_build_ipv4( + LIBNET_UDP_H, + 0, + 242, + 0, + 64, + IPPROTO_UDP, + 0, /* NEW: checksum */ + src_ip, + dst_ip, + NULL, + 0, + l, /* NEW: libnet context */ + 0 /* NEW: libnet ptag */ + ); + + The checksum allows an applications programmer to decide if he wants to + specify his own random value (useful in NIDS fooling) or precompute the + sum elsewhere, or leave it zero and by default libnet will take care of it + (although this is over-ridable). The libnet context is the opague + pointer we allocated earlier and will show up in just about every libnet + function call from here on out. The libnet ptag is a way to reference an + ALREADY BUILT protocol block. This is necessary if you want to change + some values of a header inside of a packet injection loop. + + So, when you call a build function, internally, it's a completely new + system. If the item you're constructing is NEW, a new pblock will be + allocated and linked onto the end of the list. It may be helpful to think + of this as a "protocol stack" because you MUST build your packets IN + ORDER, from the top of the protocol stack on down (i.e.: tcp -> ip -> + ethernet). Once you build a new protocol block, it's "pushed down on the + stack" and you move on to the next. However, this analogy breaks down + because you can modify any one of these items and when they're assembled + for the final packet, libnet starts at the head of the list. It may be + MORE helpful to think of the pblock chain as a doubly linked FIFO + queue, because that's what it is. :) + + For example: + + libnet_ptag_t 1; + libnet_ptag_t 2; + libnet_ptag_t 3; + + 1 = libnet_build_data(blah, l, 0); + 2 = libnet_build_tcp(blah, l, 0); + 3 = libnet_build_ipv4(blah, l, 0); + + Will result in: + ---------- ---------- ---------- + l->protocol_blocks--->| data |----->| tcp |----->| ip | + | pblock |<-----| pblock |<-----| pblock |----| + --| ptag: 1| | ptag: 2| | ptag: 3| | + | ---------- ---------- ---------- v + | ----- + |-------------------------------------------> --- + - + + To access and change the ip header, an additional call to libnet_build_ipv4 + with the ptag argument would be made: + + libnet_build_ipv4(blah..., l, 3); + + Note that the ptag DOES NOT CHANGE. Once a pblock is built, its tag is + set in stone. + + When it comes time to write the packet to the wire, + libnet_pblock_coalesce() is called to assemble the packet fragments. + + 1) Gather up all of the pblock sizes in order to allocate one + contiguous block of memory. + 2) Copy over the packet fragments. + 3) Check each pblock to see which items need checksums, then perform + that checksum over each portion (the entire packet is needed for + some checksums). + + So that's a quick description of what's going on under the hood. There's + more, but this should be enough to get you started. + +EOF diff --git a/doc/MIGRATION b/doc/MIGRATION new file mode 100644 index 0000000..b257241 --- /dev/null +++ b/doc/MIGRATION @@ -0,0 +1,172 @@ +=============================================================================== + $Id: MIGRATION,v 1.2 2004/01/03 20:31:00 mike Exp $ + LIBNET 1.1 (c) 1998 - 2004 Mike D. Schiffman <mike@infonexus.com> + http://www.packetfactory.net/libnet +=============================================================================== + + + MIGRATING YOUR CODE AND QUICKSTART + + Using Libnet 1.1 you will find it MUCH simpler to build and write packets + than before. Instead of the previous five steps (initialize memory, + initialize network, build packet, do checksums, write packet) there are + now only three steps (initialize library, build packet, write packet). + In order to port your existing code, you will mainly be REMOVING + function calls and variables. + + 1) Start with code removal: + + - Remove all calls to libnet_init_packet() / packet malloc()ing and + all associated variables. + - Remove all calls to libnet_open_raw_sock() / libnet_open_link_layer() + and all associated variables. + - Remove all calls to libnet_do_checksum() and all associated + variables. + + 2) Continue with code addition and modification: + + - You will need a single "libnet_t *l" which is your libnet file + context and an error buffer: + + libnet_t *l + char errbuf[LIBNET_ERRBUF_SIZE]; + + l = libnet_init( + LIBNET_RAW4, /* or LIBNET_LINK or LIBNET_RAW6 */ + NULL, /* or device if you using LIBNET_LINK */ + errbuf); + + - The libnet_build functions are largely unchanged with a few + important differences: + + 1) Packets headers MUST be stacked IN ORDER. This is + intuitive and shouldn't be a problem. Due to the way + individual packet header memory is allocated and how + packet pieces are combined to build a packet they HAVE to + be built IN ORDER, from the high end of the protocol stack + on down. ie: using the raw interface to build a NTP + packet, you would: + libnet_build_ntp(...) + libnet_build_udp(...) + libnet_build_ipv4(...) + To build the same packet using the LINK interface on + top of ethernet you would: + libnet_build_ntp(...) + libnet_build_udp(...) + libnet_build_ipv4(...) + libnet_build_ethernet(...) + 1a) There is the option now of using libnet_autobuild_ipv4() + and libnet_autobuild_ethernet() which have fewer + arguments and smaller stack frames and are a bit more + convenient. + 2) The libnet_build functions return a libnet_ptag_t datatype + on success or -1 on error. This ptag is your + "protocol/packet tag" so you can find this header again + if you needed to modify it later on. If you don't need + to modify the packet header you can throw this value + away. You should definitely check for error now on + your build functions. Alot's going on down there fellas. + 2a) NOTE that after packets are built, they may accessed + independently of construction order via the saved ptag. + 3) They NO LONGER ACCEPT BUFFER ARGUMENTS. This is ALL + done internally. The last TWO arguments are the libnet + context you created in your call to libnet_init() and + an OPTIONAL ptag argument. The ptag argument, if non-zero, + specifes a packet tag to an ALREADY EXISTING packet header + that will be OVERWRITTEN with the values specified in + this libnet_build function call. This is how you modify + existing packet header pieces. If this ptag is 0, + a new protocol block is allocated and the packet is + pushed down on the "protocol stack". + 4) For the functions that build headers that have checksums + these are NOW SPECIFIED AS AN ARGUMENT. This adds more + flexibility in how checksums are done (you can leave the + field 0, put in a random value, precompute it on your own, + or let the library do it). By default, when you build + a header, a "DO_CHECKSUM" flag will be set. This means + the library will compute the checksum for the header + and possibly over the data before the packet is written. + To clear this flag, there is a special macro you + can call on the ptag refering to that header. + 5) For the functions that have a length, it now specifies + the TOTAL packet length from that protocol unit on down. + For IP, that would be the entire packet length. For + TCP, that would be TCP and any possible data. + 6) Nomenclature support for the eventual support of ipv6 + has been added. + + libnet_ptag_t ip_tag; + libnet_ptag_t tcp_tag; + + tcp_tag = libnet_build_tcp( + src_prt, /* source TCP port */ + dst_prt, /* destination TCP port */ + 0xffff, /* sequence number */ + 0x53, /* acknowledgement number */ + TH_SYN, /* control flags */ + 1024, /* window size */ + 0xd00d, /* checksum */ + 0, /* urgent pointer */ + LIBNET_TCP_H /* TCP packet size */ + NULL, /* payload (none) */ + 0, /* payload length */ + l, /* libnet context */ + 0); /* ptag */ + + ip_tag = libnet_build_ipv4( + LIBNET_TCP_H + LIBNET_IPV4_H,/* total packet len */ + IPTOS_LOWDELAY, /* tos */ + ip_id, /* IP ID */ + 0, /* IP Frag */ + 64, /* TTL */ + IPPROTO_TCP, /* protocol */ + 0, /* checksum */ + src_ip, /* source ip */ + dst_ip, /* dest ip */ + NULL, /* payload (none) */ + 0, /* payload size */ + l, /* libnet context */ + 0); /* ptag */ + + Now, if you wanted to modify one of these headers in a loop + somewhere you would: + + int i; + for (ip_tag, tcp_tag = LIBNET_PTAG_INITIALIZER, i = 0; i < 10; i++) + { + tcp_tag = libnet_build_tcp(++src_prt, ..., l, tcp_tag); + ip_tag = libnet_build_ipv4(..., ++ip_id, ..., l, ip_tag); + /* do something */ + } + Since we are specifying a ptag for an existing header, the + build function will NOT create a new header and append it to + the list, it will FIND the one referenced by the ptag and UPDATE + it. Since there is nothing new being created, order is NOT + important here. + + Also note that it's perfectly fine to wrap the loop around the + initial building of the packets. Since we're initializing the + ptags (to be zero), the first call into the builder functions + will allocate the memory and create the packet blocks. These + calls will return ptag values. The next calls will modify + these headers since the ptags will not be NULL. + + - Finally, we write the packet. Checksums are computed, by default + for each protocol header that requires one. If the user specifies + a non-zero value, by default, this will be used INSTEAD of a + libnet computed checksum. This behavior is overridable with: + + Turn ON checksums for header referenced by ptag: + libnet_toggle_checksum(l, ptag, 1) + + Turn OFF checksums for header referenced by ptag: + libnet_toggle_checksum(l, ptag, 0) + + Note, the packet header MUST exist before you can toggle this setting. + + int c; + c = libnet_write(l); + + Boom. You're done. Now go read the sample code. + +EOF diff --git a/doc/Makefile.am b/doc/Makefile.am new file mode 100644 index 0000000..c1417a1 --- /dev/null +++ b/doc/Makefile.am @@ -0,0 +1,10 @@ +EXTRA_DIST = CHANGELOG CONTRIB COPYING DESIGN_NOTES \ + libnet.doxygen.conf MIGRATION PACKET_BUILDING PORTED \ + RAWSOCKET_NON_SEQUITUR TODO + +doc: + cd $(top_srcdir) && doxygen doc/libnet.doxygen.conf + +SUBDIRS = man html + + diff --git a/doc/Makefile.in b/doc/Makefile.in new file mode 100644 index 0000000..22f0b3d --- /dev/null +++ b/doc/Makefile.in @@ -0,0 +1,572 @@ +# Makefile.in generated by automake 1.11.1 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, +# 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, +# Inc. +# This Makefile.in is free software;

Schiffman <mike@infonexus.com> + http://www.packetfactory.net/libnet +=============================================================================== + + + ADDING A NEW PACKET BUILDER, STATIC HEADER SIZE + +Adding a new packet building module to libnet is usually pretty simple. The +following short document details how to add a packet builder to libnet for a +protocol that has a static header size. We'll use the Sebek protocol as an +example to walk through the process. + +1) Make sure you have a good reference for the protocol in question. Be it an + RFC or an official release doc from the author or vendor, you'll need + something comprehensive. For Sebek, the comprehensive reference is here: + http://project.honeynet.org. + +2) Figure out how big the header is and add it to the top of libnet-headers.h: + +#define LIBNET_SEBEK_H 0x30 /* sebek header: 48 bytes */ + +3) Create the protocol header structure and add it to the end of + libnet-headers.h. Take care to use POSIX datatypes to define all of your + values. Structure naming conventions are more or less up to you. Since + they're never exported to the user, it's not a big deal, but try to keep + them short and descriptive. Convention is to add the symbolic constant + #defines above the structure members they apply to. + +/* + * Sebek header + * Static header size: 48 bytes + */ +struct libnet_sebek_hdr +{ + u_int32_t magic; /* identify packets that should be hidden */ + u_int16_t version; /* protocol version, currently 1 */ +#define SEBEK_PROTO_VERSION 1 + u_int16_t type; /* type of record */ +#define SEBEK_TYPE_READ 0 /* currently, only read is supported */ +#define SEBEK_TYPE_WRITE 1 + u_int32_t counter; /* PDU counter */ + u_int32_t time_sec; /* EPOCH timer */ + u_int32_t time_usec; /* residual microseconds */ + u_int32_t pid; /* PID */ + u_int32_t uid; /* UID */ + u_int32_t fd; /* FD */ +#define SEBEK_CMD_LENGTH 12 + u_int8_t cmd[SEBEK_CMD_LENGTH]; /* 12 first characters of the command */ + u_int32_t length; /* PDU length */ +}; + +3) Append a pblock identifier to the end of the list in libnet-structures.h. + The ID number is not imporant as long as it is UNIQUE. As such, just find + the last entry, append the new entry after it, and increase the pblock ID + by one: + +#define LIBNET_PBLOCK_SEBEK_H 0x3f /* Sebek header */ + +4) Create your new builder file in src/.

(toolkit) allowing the application programmer to construct and inject network packets. It provides a portable and simplified interface for low-level network packet shaping, handling and injection. Libnet hides much of the tedium of packet creation from the application programmer such as multiplexing, buffer management, arcane packet header information, byte-ordering, OS-dependent issues, and much more. Libnet features portable packet creation interfaces at the IP layer and link layer, as well as a host of supplementary and complementary functionality. Using libnet, quick and simple packet assembly applications can be whipped up with little effort.

class="anchor" id="PBF"></a> +Packet Builder Functions</h2> +<p>The core of libnet is the platform-independent packet-building functionality. These functions enable an application programmer to build protocol headers (and data) in a simple and consistent manner without having to worry (too much) about low-level network odds and ends. Each libnet_build() function builds a piece of a packet (generally a protocol header). While it is perfectly possible to build an entire, ready-to-transmit packet with a single call to a libnet_build() function, generally more than one builder-class function call is required to construct a full packet. A complete wire-ready packet generally consists of more than one piece. Every function that builds a protocol header takes a series of arguments roughly corresponding to the header values as they appear on the wire. This process is intuitive but often makes for functions with huge prototypes and large stack frames. One important thing to note is that you must call these functions in order, corresponding to how they should appear on the wire (from the highest protocol layer on down). This building process is intuitive; it approximates what happens in an operating system kernel. In other words, to build a Network Time Protocol (NTP) packet by using the link-layer interface, the application programmer would call the libnet_build() functions in the following order: 1. <a class="el" href="libnet-functions_8h.html#a8a13581c5722c0ee77c2486465c10275">libnet_build_ntp()</a> 2. <a class="el" href="libnet-functions_8h.html#a1dee17aa5276df3587ee276b1b90d8fa">libnet_build_udp()</a> 3. <a class="el" href="libnet-functions_8h.html#a326cf29f24a37dc9232b8b6a56a3f12f">libnet_build_ipv4()</a> 4. <a class="el" href="libnet-functions_8h.html#ac0e53234dfc5205142b0f53c69ab46ae">libnet_build_ethernet()</a> This ordering is essential for libnet 1.1.x to properly link together the packet internally (previous libnet versions did not have the requirement).</p> +<h3><a class="anchor" id="TPI"></a> +The Payload Interface</h3> +<p>The payload interface specifies an optional way to include data directly after the protocol header in question. You can use this function for a variety of purposes, including the following:</p> +<ul> +<li>Including additional or arbitrary protocol header information that is not available from a libnet interface</li> +<li>Including a packet payload (data segment)</li> +<li>Building another protocol header that is not available from a libnet interface To employ the interface, the application programmer should construct the i payload data and pass a const uint8_t * to this data and its size to the desired libnet_build() function. Libnet handles the rest.</li> +</ul> +<p>It is important to note that some functions (notably the IPv6 builders) do use the payload interface to specify variable length but ostensibly non-optional data. See the individual libnet_build_ipv6*() functions for more information.</p> +<h3><a class="anchor" id="PT"></a> +Protocol Tags and Packet Builder Return Values</h3> +<p>Libnet uses the protocol tag (ptag) to identify individual pieces of a packet after being created. A new ptag results every time a libnet_build() function with an empty (0) ptag argument completes successfully. This new ptag now refers to the packet piece just created. The application programmer's responsibility is to save this value if he or she plans to modify this particular portion later on in the program. If the application programmer needs to modify some portion of that particular packet piece again, he or she calls the same libnet_build() function specifying the saved ptag argument. Libnet then searches for that packet piece and modifies it rather than creating a new one. Upon failure for any reason, libnet_build() functions return -1; <a class="el" href="libnet-functions_8h.html#a36c0b24a4926a8f5d9d392836e915f2e">libnet_geterror()</a> tells you why. Builds an IEEE 802.1q VLAN tagging header. Depending on the value of len_proto, the function wraps the 802.1q header inside either an IEEE 802.3 header or an RFC 894 Ethernet II (DIX) header (both resulting in an 18-byte frame). If len is 1500 or less, most receiving protocol stacks parse the frame as an IEEE 802.3 encapsulated frame. If len is one of the Ethernet type values, most protocol stacks parse the frame as an RFC 894 Ethernet II encapsulated frame. Note the length value is calculated without the 802.1q header of 18 bytes. </p> +<dl><dt><b>Parameters:</b></dt><dd> + <table class="params"> + <tr><td class="paramname">dst</td><td>pointer to a six

If the injection_type is LIBNET_LINK or LIBNET_LINK_ADV, the function initializes the injection primitives for the link-layer interface enabling the application programmer to build packets starting at the data-link layer (which also provides more granular control over the IP layer). If libnet uses the link-layer and the device argument is non-NULL, the function attempts to use the specified network device for packet injection. This is either a canonical string that references the device (such as "eth0" for a 100MB Ethernet card on Linux or "fxp0" for a 100MB Ethernet card on OpenBSD) or the dots and decimals representation of the device's IP address (192.168.0.1). If device is NULL, libnet attempts to find a suitable device to use. If the injection_type is LIBNET_RAW4 or LIBNET_RAW4_ADV, the function initializes the injection primitives for the IPv4 raw socket interface. The final argument, err_buf, should be a buffer of size LIBNET_ERRBUF_SIZE and holds an error message if the function fails. This function requires root privileges to execute successfully.

Switches auto-checksumming on or off for the specified ptag. If mode is set to LIBNET_ON, libnet will mark the specificed ptag to calculate a checksum for the ptag prior to injection. This assumes that the ptag refers to a protocol that has a checksum field. If mode is set to LIBNET_OFF, libnet will clear the checksum flag and no checksum will be computed prior to injection. This assumes that the programmer will assign a value (zero or otherwise) to the checksum field. Often times this is useful if a precomputed checksum or some other predefined value is going to be used.

These functions enable an application programmer to build protocol headers (and data) in a simple and consistent manner without having to worry (too much) about low-level network odds and ends. Each libnet_build() function builds a piece of a packet (generally a protocol header). While it is perfectly possible to build an entire, ready-to-transmit packet with a single call to a libnet_build() function, generally more than one builder-class function call is required to construct a full packet. A complete wire-ready packet generally consists of more than one piece. Every function that builds a protocol header takes a series of arguments roughly corresponding to the header values as they appear on the wire. This process is intuitive but often makes for functions with huge prototypes and large stack frames. One important thing to note is that you must call these functions in order, corresponding to how they should appear on the wire (from the highest protocol layer on down). This building process is intuitive; it approximates what happens in an operating system kernel. In other words, to build a Network Time Protocol (NTP) packet by using the link-layer interface, the application programmer would call the libnet_build() functions in the following order: 1. \fBlibnet_build_ntp()\fP 2. \fBlibnet_build_udp()\fP 3. \fBlibnet_build_ipv4()\fP 4. \fBlibnet_build_ethernet()\fP This ordering is essential for libnet 1.1.x to properly link together the packet internally (previous libnet versions did not have the requirement). +.SS "The Payload Interface" +The payload interface specifies an optional way to include data directly after the protocol header in question. You can use this function for a variety of purposes, including the following: +.IP "\(bu" 2 +Including additional or arbitrary protocol header information that is not available from a libnet interface +.IP "\(bu" 2 +Including a packet payload (data segment) +.IP "\(bu" 2 +Building another protocol header that is not available from a libnet interface To employ the interface, the application programmer should construct the i payload data and pass a const uint8_t * to this data and its size to the desired libnet_build() function. Libnet handles the rest. +.PP +.PP +It is important to note that some functions (notably the IPv6 builders) do use the payload interface to specify variable length but ostensibly non-optional data. See the individual libnet_build_ipv6*() functions for more information. +.SS "Protocol Tags and Packet Builder Return Values" +Libnet uses the protocol tag (ptag) to identify individual pieces of a packet after being created. A new ptag results every time a libnet_build() function with an empty (0) ptag argument completes successfully. This new ptag now refers to the packet piece just created. The application programmer's responsibility is to save this value if he or she plans to modify this particular portion later on in the program. If the application programmer needs to modify some portion of that particular packet piece again, he or she calls the same libnet_build() function specifying the saved ptag argument. Libnet then searches for that packet piece and modifies it rather than creating a new one. Upon failure for any reason, libnet_build() functions return -1; \fBlibnet_geterror()\fP tells you why. Builds an IEEE 802.1q VLAN tagging header. Depending on the value of len_proto, the function wraps the 802.1q header inside either an IEEE 802.3 header or an RFC 894 Ethernet II (DIX) header (both resulting in an 18-byte frame). If len is 1500 or less, most receiving protocol stacks parse the frame as an IEEE 802.3 encapsulated frame. If len is one of the Ethernet type values, most protocol stacks parse the frame as an RFC 894 Ethernet II encapsulated frame. Note the length value is calculated without the 802.1q header of 18 bytes. +.PP +\fBParameters:\fP +.RS 4 +\fIdst\fP pointer to a six byte source ethernet address +.br +\fIsrc\fP pointer to a six byte destination ethernet address +.br +\fItpi\fP tag protocol identifier +.br +\fIpriority\fP priority +.br +\fIcfi\fP canonical format indicator +.br +\fIvlan_id\fP vlan identifier +.br +\fIlen_proto\fP length (802.3) protocol (Ethernet II) +.br +\fIpayload\fP optional payload or NULL +.br +\fIpayload_s\fP payload length or 0 +.br +\fIl\fP pointer to a libnet context +.br +\fIptag\fP protocol tag to modify an existing header, 0 to build a new one +.RE +.PP +\fBReturns:\fP +.RS 4 +protocol tag value on success, -1 on error +.RE +.PP + +.SS "libnet_ptag_t libnet_build_802_1x (uint8_teap_ver, uint8_teap_type, uint16_tlength, const uint8_t *payload, uint32_tpayload_s, libnet_t *l, libnet_ptag_tptag)"Builds an IEEE 802.1x extended authentication protocol header. +.PP +\fBParameters:\fP +.RS 4 +\fIeap_ver\fP the EAP version +.br +\fIeap_type\fP the EAP type +.br +\fIlength\fP frame length +.br +\fIpayload\fP optional payload or NULL +.br +\fIpayload_s\fP payload length or 0 +.br +\fIl\fP pointer to a libnet context +.br +\fIptag\fP protocol tag to modify an existing header, 0 to build a new one +.RE +.PP +\fBReturns:\fP +.RS 4 +protocol tag value on success, -1 on error +.RE +.PP + +.SS "libnet_ptag_t libnet_build_802_2 (uint8_tdsap, uint8_tssap, uint8_tcontrol, const uint8_t *payload, uint32_tpayload_s, libnet_t *l, libnet_ptag_tptag)"Builds an IEEE 802.2 LLC header. +.PP +\fBParameters:\fP +.RS 4 +\fIdsap\fP destination service access point +.br +\fIssap\fP source service access point +.br +\fIcontrol\fP control field +.br +\fIpayload\fP optional payload or NULL +.br +\fIpayload_s\fP payload length or 0 +.br +\fIl\fP pointer to a libnet context +.br +\fIptag\fP protocol tag to modify an existing header, 0 to build a new one +.RE +.PP +\fBReturns:\fP +.RS 4 +protocol tag value on success, -1 on error +.RE +.PP + +.SS "libnet_ptag_t libnet_build_802_2snap (uint8_tdsap, uint8_tssap, uint8_tcontrol, uint8_t *oui, uint16_ttype, const uint8_t *payload, uint32_tpayload_s, libnet_t *l, libnet_ptag_tptag)"Builds an IEEE 802.2 LLC SNAP header. +.PP +\fBParameters:\fP +.RS 4 +\fIdsap\fP destination service access point +.br +\fIssap\fP source service access point +.br +\fIcontrol\fP control field +.br +\fIoui\fP Organizationally Unique Identifier +.br +\fItype\fP upper layer protocol +.br +\fIpayload\fP optional payload or NULL +.br +\fIpayload_s\fP payload length or 0 +.br +\fIl\fP pointer to a libnet context +.br +\fIptag\fP protocol tag to modify an existing header, 0 to build a new one +.RE +.PP +\fBReturns:\fP +.RS 4 +protocol tag value on success, -1 on error +.RE +.PP + +.SS "libnet_ptag_t libnet_build_802_3 (const uint8_t *dst, const uint8_t *src, uint16_tlen, const uint8_t *payload, uint32_tpayload_s, libnet_t *l, libnet_ptag_tptag)"Builds an IEEE 802.3 header.

It initializes the library and returns a libnet context. If the injection_type is LIBNET_LINK or LIBNET_LINK_ADV, the function initializes the injection primitives for the link-layer interface enabling the application programmer to build packets starting at the data-link layer (which also provides more granular control over the IP layer). If libnet uses the link-layer and the device argument is non-NULL, the function attempts to use the specified network device for packet injection. This is either a canonical string that references the device (such as 'eth0' for a 100MB Ethernet card on Linux or 'fxp0' for a 100MB Ethernet card on OpenBSD) or the dots and decimals representation of the device's IP address (192.168.0.1). If device is NULL, libnet attempts to find a suitable device to use. If the injection_type is LIBNET_RAW4 or LIBNET_RAW4_ADV, the function initializes the injection primitives for the IPv4 raw socket interface. The final argument, err_buf, should be a buffer of size LIBNET_ERRBUF_SIZE and holds an error message if the function fails. This function requires root privileges to execute successfully.

It provides a portable and simplified + * interface for low-level network packet shaping, handling and injection. + * Libnet hides much of the tedium of packet creation from the application + * programmer such as multiplexing, buffer management, arcane packet header + * information, byte-ordering, OS-dependent issues, and much more. Libnet + * features portable packet creation interfaces at the IP layer and link layer, + * as well as a host of supplementary and complementary functionality. Using + * libnet, quick and simple packet assembly applications can be whipped up with + * little effort. With a bit more time, more complex programs can be written + * (Traceroute and ping were easily rewritten using libnet and + * <a href="www.tcpdump.org">libpcap</a>). + */ + +#ifdef __cplusplus +extern "C" { +#endif + +#include <stdio.h> +#include <string.h> +#include <unistd.h> +#include <fcntl.h> +#include <signal.h> +#include <stdlib.h> + +#if !defined(__WIN32__) +# include <sys/ioctl.h> +#endif /* __WIN32__ */ + +#if defined(HAVE_SYS_SOCKIO_H) && !defined(SIOCGIFADDR) +# include <sys/sockio.h> +#endif + +#include <sys/stat.h> +#include <sys/types.h> +#include <ctype.h> + +#if !defined(__WIN32__) +# include <sys/socket.h> +# include <net/if.h> +#else /* __WIN32__ */ +# if (__CYGWIN__) +# include <sys/socket.h> +# endif +# include <ws2tcpip.h> +# include <windows.h> +# include <winsock2.h> +# include <win32/in_systm.h> +#endif /* __WIN32__ */ + +#if !(__linux__) && !(__WIN32__) && !(__APPLE__) && !(__CYGWIN__) && !(__GNU__) +#else /* __linux__ */ +# if (HAVE_NET_ETHERNET_H) +# include <net/ethernet.h> +# endif /* HAVE_NET_ETHERNET_H */ +#endif /* __linux__ */ + +#if !defined(__WIN32__) +# include <arpa/inet.h> +# include <sys/time.h> +# include <netdb.h> +#endif /* __WIN32__ */ + +#include <errno.h> +#include <stdarg.h> + +#define LIBNET_VERSION "@PACKAGE_VERSION@" + +#define @ENDIANESS@ 1 + +#include "./libnet/libnet-types.h" +#include "./libnet/libnet-macros.h" +#include "./libnet/libnet-headers.h" +#include "./libnet/libnet-structures.h" +#include "./libnet/libnet-asn1.h" +#include "./libnet/libnet-functions.h" + +#ifdef __cplusplus +} +#endif + +#endif /* __LIBNET_H */ + +/* EOF */ diff --git a/include/libnet/Makefile.am b/include/libnet/Makefile.am new file mode 100644 index 0000000..ef43b53 --- /dev/null +++ b/include/libnet/Makefile.am @@ -0,0 +1,12 @@ +# $Id: Makefile.am,v 1.2 2003/10/18 17:20:03 mike Exp $ + +include $(top_srcdir)/Makefile.am.common + +libnetincludedir = $(includedir)/libnet + +libnetinclude_HEADERS = libnet-asn1.h \ + libnet-functions.h \ + libnet-headers.h \ + libnet-macros.h \ + libnet-structures.h \ + libnet-types.h diff --git a/include/libnet/Makefile.in b/include/libnet/Makefile.in new file mode 100644 index 0000000..d78d849 --- /dev/null +++ b/include/libnet/Makefile.in @@ -0,0 +1,484 @@ +# Makefile.in generated by automake 1.11.1 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, +# 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, +# Inc. +# This Makefile.in is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +@SET_MAKE@ + +# $Id: Makefile.am,v 1.2 2003/10/18 17:20:03 mike Exp $ + +# $Id: Makefile.am.common,v 1.3 2004/01/03 20:31:00 mike Exp $ +# +# Libnet automake information file +# Copyright (c) 1998 - 2004 Mike D.

These functions enable an application programmer to build + * protocol headers (and data) in a simple and consistent manner without having + * to worry (too much) about low-level network odds and ends. Each + * libnet_build() function builds a piece of a packet (generally a protocol + * header). While it is perfectly possible to build an entire, + * ready-to-transmit packet with a single call to a libnet_build() function, + * generally more than one builder-class function call is required to construct + * a full packet. A complete wire-ready packet generally consists of more than + * one piece. + * Every function that builds a protocol header takes a series of arguments + * roughly corresponding to the header values as they appear on the wire. This + * process is intuitive but often makes for functions with huge prototypes and + * large stack frames. + * One important thing to note is that you must call these functions in order, + * corresponding to how they should appear on the wire (from the highest + * protocol layer on down). This building process is intuitive; it approximates + * what happens in an operating system kernel. In other words, to build a + * Network Time Protocol (NTP) packet by using the link-layer interface, the + * application programmer would call the libnet_build() functions in the + * following order: + * 1. libnet_build_ntp() + * 2. libnet_build_udp() + * 3. libnet_build_ipv4() + * 4. libnet_build_ethernet() + * This ordering is essential for libnet 1.1.x to properly link together the + * packet internally (previous libnet versions did not have the requirement). + * + * @subsection TPI The Payload Interface + * + * The payload interface specifies an optional way to include data directly + * after the protocol header in question. You can use this function for a + * variety of purposes, including the following: + * - Including additional or arbitrary protocol header information that is not + * available from a libnet interface + * - Including a packet payload (data segment) + * - Building another protocol header that is not available from a libnet + * interface + * To employ the interface, the application programmer should construct the i + * payload data and pass a const uint8_t * to this data and its size to the desired + * libnet_build() function. Libnet handles the rest. + * + * It is important to note that some functions (notably the IPv6 builders) do + * use the payload interface to specify variable length but ostensibly + * non-optional data. See the individual libnet_build_ipv6*() functions for + * more information. + * + * @subsection PT Protocol Tags and Packet Builder Return Values + * + * Libnet uses the protocol tag (ptag) to identify individual pieces of a + * packet after being created. A new ptag results every time a libnet_build() + * function with an empty (0) ptag argument completes successfully. This new + * ptag now refers to the packet piece just created. The application + * programmer's responsibility is to save this value if he or she plans to + * modify this particular portion later on in the program. If the application + * programmer needs to modify some portion of that particular packet piece + * again, he or she calls the same libnet_build() function specifying the + * saved ptag argument.
