Summary for 0.7 release 523 524 Added pcap_findalldevs() call to get list of interfaces in a MI way. 525 526 pcap_stats() has been documented as to what its counters mean on 527 each platform. 528 529Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release 530 531 New Linux libpcap implementation, which, in 2.2 and later 532 kernels, uses PF_PACKET sockets and supports kernel packet 533 filtering (if compiled into the kernel), and supports the "any" 534 device for capturing on all interfaces. Cleans up promiscuous 535 mode better on pre-2.2 kernels, and has various other fixes 536 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, 537 doesn't show duplicate packets on loopback interface, etc.). 538 539 Fixed HP-UX libpcap implementation to correctly get the PPA for 540 an interface, to allow interfaces to be opened by interface name. 541 542 libpcap savefiles have system-independent link-layer type values 543 in the header, rather than sometimes platform-dependent DLT_ 544 values, to make it easier to exchange capture files between 545 different OSes. 546 547 Non-standard capture files produced by some Linux tcpdumps, e.g. 548 the one from Red Hat Linux 6.2 and later, can now be read. 549 550 Updated autoconf stock files. 551 552 Filter expressions can filter on VLAN IDs and various OSI 553 protocols, and work on Token Ring (with non-source-routed 554 packets). 555 556 "pcap_open_dead()" added to allow compiling filter expressions 557 to pcap code without opening a capture device or capture file. 558 559 Header files fixed to allow use in C++ programs. 560 561 Removed dependancy on native headers for packet layout. 562 Removed Linux specific headers that were shipped. 563 564 Security fixes: Strcpy replaced with strlcpy, sprintf replaced 565 with snprintf. 566 567 Fixed bug that could cause subsequent "pcap_compile()"s to fail 568 erroneously after one compile failed. 569 570 Assorted other bug fixes. 571 572 README.aix and README.linux files added to describe 573 platform-specific issues. 574 575 "getifaddrs()" rather than SIOCGIFCONF used, if available. 576 577v0.5 Sat Jun 10 11:09:15 PDT 2000 578 579itojun@iijlab.net 580- Brought in KAME IPv6/IPsec bpf compiler. 581- Fixes for NetBSD. 582- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), 583 and changes to work around different BSDs having different DLT_ types 584 with the same numeric value. 585 586Assar Westerlund <assar@sics.se> 587- Building outside the source code tree fixed. 588- Changed to write out time stamps with 32-bit seconds and microseconds 589 fields, regardless of whether those fields are 32 bits or 64 bits in 590 the OS's native "struct timeval". 591- Changed "pcap_lookupdev()" to dynamically grow the buffer into which 592 the list of interfaces is read as necessary in order to hold the 593 entire list. 594 595Greg Troxel <gdt@ir.bbn.com> 596- Added a new "pcap_compile_nopcap()", which lets you compile a filter 597 expression into a BPF program without having an open live capture or 598 capture file. 599 600v0.4 Sat Jul 25 12:40:09 PDT 1998 601 602- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill 603 Fenner (fenner@parc.xerox.com) 604 605- Fix alignment problem with FDDI under DLPI. This was causing core 606 dumps under Solaris. 607 608- Added configure options to disable flex and bison. Resulted from a 609 bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added 610 options to disable gcc and to force a particular packet capture type. 611 612- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks 613 to John Hawkinson (jhawk@mit.edu) 614 615- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not 616 supply any "link layer" data. 617 618- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type. 619 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch) 620 621- Change IRIX PPP to use DLT_RAW since the kernel does not supply any 622 "link layer" data. 623 624- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header 625 formats. 626 627- Added some new SGI snoop interface types.

Thanks to Charlie Slater 764 (cslater@imatek.com) for pointing this out. 765 766- Removed FDDI ifdef's, they aren't really needed. Resulted from report 767 by Gary Veum (veum@boa.gsfc.nasa.gov). 768 769- Add pcap-null.c which allows offline use of libpcap on systems that 770 don't support live package capture. This feature resulting from a 771 request from Jan van Oorschot (j.p.m.voorschot@et.tudelft.nl). 772 773- Make bpf_compile() reentrant.
