Summary for 0.6 release 52 53 New Linux libpcap implementation, which, in 2.2 and later 54 kernels, uses PF_PACKET sockets and supports kernel packet 55 filtering (if compiled into the kernel), and supports the "any" 56 device for capturing on all interfaces. Cleans up promiscuous 57 mode better on pre-2.2 kernels, and has various other fixes 58 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, 59 doesn't show duplicate packets on loopback interface, etc.). 60 61 Fixed HP-UX libpcap implementation to correctly get the PPA for 62 an interface, to allow interfaces to be opened by interface name. 63 64 libpcap savefiles have system-independent link-layer type values 65 in the header, rather than sometimes platform-dependent DLT_ 66 values, to make it easier to exchange capture files between 67 different OSes. 68 69 Non-standard capture files produced by some Linux tcpdumps, e.g. 70 the one from Red Hat Linux 6.2 and later, can now be read. 71 72 Updated autoconf stock files. 73 74 Filter expressions can filter on VLAN IDs and various OSI 75 protocols, and work on Token Ring (with non-source-routed 76 packets). 77 78 "pcap_open_dead()" added to allow compiling filter expressions 79 to pcap code without opening a capture device or capture file. 80 81 Header files fixed to allow use in C++ programs. 82 83 Removed dependancy on native headers for packet layout. 84 Removed Linux specific headers that were shipped. 85 86 Security fixes: Strcpy replaced with strlcpy, sprintf replaced 87 with snprintf. 88 89 Fixed bug that could cause subsequent "pcap_compile()"s to fail 90 erroneously after one compile failed. 91 92 Assorted other bug fixes. 93 94 README.aix and README.linux files added to describe 95 platform-specific issues. 96 97 "getifaddrs()" rather than SIOCGIFCONF used, if available. 98 99v0.5 Sat Jun 10 11:09:15 PDT 2000 100 101itojun@iijlab.net 102- Brought in KAME IPv6/IPsec bpf compiler. 103- Fixes for NetBSD. 104- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), 105 and changes to work around different BSDs having different DLT_ types 106 with the same numeric value. 107 108Assar Westerlund <assar@sics.se> 109- Building outside the source code tree fixed. 110- Changed to write out time stamps with 32-bit seconds and microseconds 111 fields, regardless of whether those fields are 32 bits or 64 bits in 112 the OS's native "struct timeval". 113- Changed "pcap_lookupdev()" to dynamically grow the buffer into which 114 the list of interfaces is read as necessary in order to hold the 115 entire list. 116 117Greg Troxel <gdt@ir.bbn.com> 118- Added a new "pcap_compile_nopcap()", which lets you compile a filter 119 expression into a BPF program without having an open live capture or 120 capture file. 121 122v0.4 Sat Jul 25 12:40:09 PDT 1998 123 124- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill 125 Fenner (fenner@parc.xerox.com) 126 127- Fix alignment problem with FDDI under DLPI. This was causing core 128 dumps under Solaris. 129 130- Added configure options to disable flex and bison. Resulted from a 131 bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added 132 options to disable gcc and to force a particular packet capture type. 133 134- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks 135 to John Hawkinson (jhawk@mit.edu) 136 137- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not 138 supply any "link layer" data. 139 140- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type. 141 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch) 142 143- Change IRIX PPP to use DLT_RAW since the kernel does not supply any 144 "link layer" data. 145 146- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header 147 formats. 148 149- Added some new SGI snoop interface types. Thanks to Steve Alexander 150 (sca@refugee.engr.sgi.com) 151 152- Fixes for HP-UX 10.20 (which is similar to HP-UX 9). Thanks to 153 Richard Allen (ra@hp.is) and Steinar Haug (sthaug@nethelp.no) 154 155- Fddi supports broadcast as reported by Jeff Macdonald 156 (jeff@iacnet.com).

Thanks to Charlie Slater 286 (cslater@imatek.com) for pointing this out. 287 288- Removed FDDI ifdef's, they aren't really needed. Resulted from report 289 by Gary Veum (veum@boa.gsfc.nasa.gov). 290 291- Add pcap-null.c which allows offline use of libpcap on systems that 292 don't support live package capture. This feature resulting from a 293 request from Jan van Oorschot (j.p.m.voorschot@et.tudelft.nl). 294 295- Make bpf_compile() reentrant. Fix thanks to Pascal Hennequin 296 (Pascal.Hennequin@hugo.int-evry.fr). 297 298- Port to GNU autoconf. 299 300- Fix pcap-dlpi.c to work with isdn.
