Summary for 0.7 release 496 497 Added pcap_findalldevs() call to get list of interfaces in a MI way. 498 499 pcap_stats() has been documented as to what its counters mean on 500 each platform. 501 502Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release 503 504 New Linux libpcap implementation, which, in 2.2 and later 505 kernels, uses PF_PACKET sockets and supports kernel packet 506 filtering (if compiled into the kernel), and supports the "any" 507 device for capturing on all interfaces. Cleans up promiscuous 508 mode better on pre-2.2 kernels, and has various other fixes 509 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, 510 doesn't show duplicate packets on loopback interface, etc.). 511 512 Fixed HP-UX libpcap implementation to correctly get the PPA for 513 an interface, to allow interfaces to be opened by interface name. 514 515 libpcap savefiles have system-independent link-layer type values 516 in the header, rather than sometimes platform-dependent DLT_ 517 values, to make it easier to exchange capture files between 518 different OSes. 519 520 Non-standard capture files produced by some Linux tcpdumps, e.g. 521 the one from Red Hat Linux 6.2 and later, can now be read. 522 523 Updated autoconf stock files. 524 525 Filter expressions can filter on VLAN IDs and various OSI 526 protocols, and work on Token Ring (with non-source-routed 527 packets). 528 529 "pcap_open_dead()" added to allow compiling filter expressions 530 to pcap code without opening a capture device or capture file. 531 532 Header files fixed to allow use in C++ programs. 533 534 Removed dependancy on native headers for packet layout. 535 Removed Linux specific headers that were shipped. 536 537 Security fixes: Strcpy replaced with strlcpy, sprintf replaced 538 with snprintf. 539 540 Fixed bug that could cause subsequent "pcap_compile()"s to fail 541 erroneously after one compile failed. 542 543 Assorted other bug fixes. 544 545 README.aix and README.linux files added to describe 546 platform-specific issues. 547 548 "getifaddrs()" rather than SIOCGIFCONF used, if available. 549 550v0.5 Sat Jun 10 11:09:15 PDT 2000 551 552itojun@iijlab.net 553- Brought in KAME IPv6/IPsec bpf compiler. 554- Fixes for NetBSD. 555- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), 556 and changes to work around different BSDs having different DLT_ types 557 with the same numeric value. 558 559Assar Westerlund <assar@sics.se> 560- Building outside the source code tree fixed. 561- Changed to write out time stamps with 32-bit seconds and microseconds 562 fields, regardless of whether those fields are 32 bits or 64 bits in 563 the OS's native "struct timeval". 564- Changed "pcap_lookupdev()" to dynamically grow the buffer into which 565 the list of interfaces is read as necessary in order to hold the 566 entire list. 567 568Greg Troxel <gdt@ir.bbn.com> 569- Added a new "pcap_compile_nopcap()", which lets you compile a filter 570 expression into a BPF program without having an open live capture or 571 capture file. 572 573v0.4 Sat Jul 25 12:40:09 PDT 1998 574 575- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill 576 Fenner (fenner@parc.xerox.com) 577 578- Fix alignment problem with FDDI under DLPI. This was causing core 579 dumps under Solaris. 580 581- Added configure options to disable flex and bison. Resulted from a 582 bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added 583 options to disable gcc and to force a particular packet capture type. 584 585- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks 586 to John Hawkinson (jhawk@mit.edu) 587 588- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not 589 supply any "link layer" data. 590 591- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type. 592 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch) 593 594- Change IRIX PPP to use DLT_RAW since the kernel does not supply any 595 "link layer" data. 596 597- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header 598 formats. 599 600- Added some new SGI snoop interface types.

Thanks to Charlie Slater 737 (cslater@imatek.com) for pointing this out. 738 739- Removed FDDI ifdef's, they aren't really needed. Resulted from report 740 by Gary Veum (veum@boa.gsfc.nasa.gov). 741 742- Add pcap-null.c which allows offline use of libpcap on systems that 743 don't support live package capture. This feature resulting from a 744 request from Jan van Oorschot (j.p.m.voorschot@et.tudelft.nl). 745 746- Make bpf_compile() reentrant.
