Summary for 0.7 release 58 59 Added pcap_findalldevs() call to get list of interfaces in a MI way. 60 61 pcap_stats() has been documented as to what its counters mean on 62 each platform. 63 64Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release 65 66 New Linux libpcap implementation, which, in 2.2 and later 67 kernels, uses PF_PACKET sockets and supports kernel packet 68 filtering (if compiled into the kernel), and supports the "any" 69 device for capturing on all interfaces. Cleans up promiscuous 70 mode better on pre-2.2 kernels, and has various other fixes 71 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, 72 doesn't show duplicate packets on loopback interface, etc.). 73 74 Fixed HP-UX libpcap implementation to correctly get the PPA for 75 an interface, to allow interfaces to be opened by interface name. 76 77 libpcap savefiles have system-independent link-layer type values 78 in the header, rather than sometimes platform-dependent DLT_ 79 values, to make it easier to exchange capture files between 80 different OSes. 81 82 Non-standard capture files produced by some Linux tcpdumps, e.g. 83 the one from Red Hat Linux 6.2 and later, can now be read. 84 85 Updated autoconf stock files. 86 87 Filter expressions can filter on VLAN IDs and various OSI 88 protocols, and work on Token Ring (with non-source-routed 89 packets). 90 91 "pcap_open_dead()" added to allow compiling filter expressions 92 to pcap code without opening a capture device or capture file. 93 94 Header files fixed to allow use in C++ programs. 95 96 Removed dependancy on native headers for packet layout. 97 Removed Linux specific headers that were shipped. 98 99 Security fixes: Strcpy replaced with strlcpy, sprintf replaced 100 with snprintf. 101 102 Fixed bug that could cause subsequent "pcap_compile()"s to fail 103 erroneously after one compile failed. 104 105 Assorted other bug fixes. 106 107 README.aix and README.linux files added to describe 108 platform-specific issues. 109 110 "getifaddrs()" rather than SIOCGIFCONF used, if available. 111 112v0.5 Sat Jun 10 11:09:15 PDT 2000 113 114itojun@iijlab.net 115- Brought in KAME IPv6/IPsec bpf compiler. 116- Fixes for NetBSD. 117- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), 118 and changes to work around different BSDs having different DLT_ types 119 with the same numeric value. 120 121Assar Westerlund <assar@sics.se> 122- Building outside the source code tree fixed. 123- Changed to write out time stamps with 32-bit seconds and microseconds 124 fields, regardless of whether those fields are 32 bits or 64 bits in 125 the OS's native "struct timeval". 126- Changed "pcap_lookupdev()" to dynamically grow the buffer into which 127 the list of interfaces is read as necessary in order to hold the 128 entire list. 129 130Greg Troxel <gdt@ir.bbn.com> 131- Added a new "pcap_compile_nopcap()", which lets you compile a filter 132 expression into a BPF program without having an open live capture or 133 capture file. 134 135v0.4 Sat Jul 25 12:40:09 PDT 1998 136 137- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill 138 Fenner (fenner@parc.xerox.com) 139 140- Fix alignment problem with FDDI under DLPI. This was causing core 141 dumps under Solaris. 142 143- Added configure options to disable flex and bison. Resulted from a 144 bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added 145 options to disable gcc and to force a particular packet capture type. 146 147- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks 148 to John Hawkinson (jhawk@mit.edu) 149 150- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not 151 supply any "link layer" data. 152 153- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type. 154 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch) 155 156- Change IRIX PPP to use DLT_RAW since the kernel does not supply any 157 "link layer" data. 158 159- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header 160 formats. 161 162- Added some new SGI snoop interface types. Thanks to Steve Alexander 163 (sca@refugee.engr.sgi.com) 164 165- Fixes for HP-UX 10.20 (which is similar to HP-UX 9). Thanks to 166 Richard Allen (ra@hp.is) and Steinar Haug (sthaug@nethelp.no) 167 168- Fddi supports broadcast as reported by Jeff Macdonald 169 (jeff@iacnet.com).

Thanks to Kevin Lai 181 (laik@gunpowder.stanford.edu) 182 183- Bind to interface name under Linux to avoid packets from multiple 184 interfaces on multi-homed hosts. Thanks to Kevin Lai 185 (laik@gunpowder.stanford.edu) 186 187- Change L_SET to SEEK_SET for HP-UX. Thanks to Roland Roberts 188 (rroberts@muller.com) 189 190- Fixed an uninitialized memory reference found by Kent Vander Velden 191 (graphix@iastate.edu) 192 193- Fixed lex pattern for IDs to allow leading digits. As reported by 194 Theo de Raadt (deraadt@cvs.openbsd.org) 195 196- Fixed Linux include file problems when using GNU libc. 197 198- Ifdef ARPHRD_FDDI since not all versions of the Linux kernel have it. 199 Reported reported by Eric Jacksch (jacksch@tenebris.ca) 200 201- Fixed bug in pcap_dispatch() that kept it from returning on packet 202 timeouts. 203 204- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check 205 for "lo" followed by an eos or digit (newer versions of Linux 206 apparently call the loopback "lo" instead of "lo0"). 207 208- Fixed Linux networking include files to use ints instead of longs to 209 avoid problems with 64 bit longs on the alpha. Thanks to Cristian 210 Gafton (gafton@redhat.com) 211 212v0.3 Sat Nov 30 20:56:27 PST 1996 213 214- Added Linux support. 215 216- Fixed savefile bugs. 217 218- Solaris x86 fix from Tim Rylance (t.rylance@elsevier.nl) 219 220- Add support for bpf kernel port filters. 221 222- Remove duplicate atalk protocol table entry. Thanks to Christian 223 Hopps (chopps@water.emich.edu) 224 225- Fixed pcap_lookupdev() to ignore nonexistent devices.

The BPF filter engine uses unsigned 297 comparison operators, while the code generator and optimizer assumed 298 signed semantics in several places. Thanks to Charlie Slater 299 (cslater@imatek.com) for pointing this out. 300 301- Removed FDDI ifdef's, they aren't really needed. Resulted from report 302 by Gary Veum (veum@boa.gsfc.nasa.gov). 303 304- Add pcap-null.c which allows offline use of libpcap on systems that 305 don't support live package capture. This feature resulting from a 306 request from Jan van Oorschot (j.p.m.voorschot@et.tudelft.nl). 307 308- Make bpf_compile() reentrant. Fix thanks to Pascal Hennequin 309 (Pascal.Hennequin@hugo.int-evry.fr). 310 311- Port to GNU autoconf. 312 313- Fix pcap-dlpi.c to work with isdn.

Thanks to Richard Stevens (rstevens@noao.edu). 346 347- Fixed configure to test for snoop before dlpi to avoid problems under 348 IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com). 349 350- Hack around deficiency in Ultrix's make. 351 352- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle 353 savefiles that have more than snapshot bytes of data in them (so we 354 can read old savefiles) and avoid writing such files. 355 356- Added checkioctl which is used with gcc to check that the 357 "fixincludes" script has been run. 358 359v0.0.3 Tue Oct 18 18:13:46 PDT 1994 360 361- Fixed configure to test for snoop before dlpi to avoid problems under 362 IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com). 363 364v0.0.2 Wed Oct 12 20:56:37 PDT 1994 365 366- Implement timeout in the dlpi pcap_open_live().

The streams ioctl timeout 375 wasn't being initialized sometimes resulting in an "NIOCSFLAGS: 376 Invalid argument" error under OSF/1. Reported by Matt Day 377 (mday@artisoft.com) and Danny Mitzel (dmitzel@whitney.hitc.com). 378 379- Turn on FDDI support by default. 380 381v0.0 Mon Jun 20 19:20:16 PDT 1994 382 383- Initial release. 384 385- Fixed bug with greater/less keywords, reported by Mark Andrews 386 (mandrews@alias.com). 387 388- Fix bug where '|' was defined as BPF_AND instead of BPF_OR, reported 389 by Elan Amir (elan@leeb.cs.berkeley.edu). 390 391- Machines with little-endian byte ordering are supported thanks to 392 Jeff Mogul. 393 394- Add hack for version 2.3 savefiles which don't have caplen and len 395 swapped thanks to Vern Paxson. 396 397- Added "&&" and "||" aliases for "and" and "or" thanks to Vern Paxson. 398 399- Added length, inbound and outbound keywords. 400
