Summary for 0.6 release 582 583 New Linux libpcap implementation, which, in 2.2 and later 584 kernels, uses PF_PACKET sockets and supports kernel packet 585 filtering (if compiled into the kernel), and supports the "any" 586 device for capturing on all interfaces. Cleans up promiscuous 587 mode better on pre-2.2 kernels, and has various other fixes 588 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, 589 doesn't show duplicate packets on loopback interface, etc.). 590 591 Fixed HP-UX libpcap implementation to correctly get the PPA for 592 an interface, to allow interfaces to be opened by interface name. 593 594 libpcap savefiles have system-independent link-layer type values 595 in the header, rather than sometimes platform-dependent DLT_ 596 values, to make it easier to exchange capture files between 597 different OSes. 598 599 Non-standard capture files produced by some Linux tcpdumps, e.g. 600 the one from Red Hat Linux 6.2 and later, can now be read. 601 602 Updated autoconf stock files. 603 604 Filter expressions can filter on VLAN IDs and various OSI 605 protocols, and work on Token Ring (with non-source-routed 606 packets). 607 608 "pcap_open_dead()" added to allow compiling filter expressions 609 to pcap code without opening a capture device or capture file. 610 611 Header files fixed to allow use in C++ programs. 612 613 Removed dependancy on native headers for packet layout. 614 Removed Linux specific headers that were shipped. 615 616 Security fixes: Strcpy replaced with strlcpy, sprintf replaced 617 with snprintf. 618 619 Fixed bug that could cause subsequent "pcap_compile()"s to fail 620 erroneously after one compile failed. 621 622 Assorted other bug fixes. 623 624 README.aix and README.linux files added to describe 625 platform-specific issues. 626 627 "getifaddrs()" rather than SIOCGIFCONF used, if available. 628 629v0.5 Sat Jun 10 11:09:15 PDT 2000 630 631itojun@iijlab.net 632- Brought in KAME IPv6/IPsec bpf compiler. 633- Fixes for NetBSD. 634- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), 635 and changes to work around different BSDs having different DLT_ types 636 with the same numeric value. 637 638Assar Westerlund <assar@sics.se> 639- Building outside the source code tree fixed. 640- Changed to write out time stamps with 32-bit seconds and microseconds 641 fields, regardless of whether those fields are 32 bits or 64 bits in 642 the OS's native "struct timeval". 643- Changed "pcap_lookupdev()" to dynamically grow the buffer into which 644 the list of interfaces is read as necessary in order to hold the 645 entire list. 646 647Greg Troxel <gdt@ir.bbn.com> 648- Added a new "pcap_compile_nopcap()", which lets you compile a filter 649 expression into a BPF program without having an open live capture or 650 capture file. 651 652v0.4 Sat Jul 25 12:40:09 PDT 1998 653 654- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill 655 Fenner (fenner@parc.xerox.com) 656 657- Fix alignment problem with FDDI under DLPI.

Also added 662 options to disable gcc and to force a particular packet capture type. 663 664- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks 665 to John Hawkinson (jhawk@mit.edu) 666 667- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not 668 supply any "link layer" data. 669 670- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type. 671 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch) 672 673- Change IRIX PPP to use DLT_RAW since the kernel does not supply any 674 "link layer" data. 675 676- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header 677 formats. 678 679- Added some new SGI snoop interface types.
