Update CHANGES to reflect more of the changes in 1.1.0.
Fix build on RHEL5.
Fix shared library build on AIX.
Thu. March 11, 2010. ken@netfunctional.ca/guy@alum.mit.edu.
Summary for 1.1.0 libpcap release
Add SocketCAN capture support
Add Myricom SNF API support
Update Endace DAG and ERF support
Add support for shared libraries on Solaris, HP-UX, and AIX
Build, install, and un-install shared libraries by default;
don't build/install shared libraries on platforms we don't support
Fix building from a directory other than the source directory
Fix compiler warnings and builds on some platforms
Update config.guess and config.sub
Support monitor mode on mac80211 devices on Linux
Fix USB memory-mapped capturing on Linux; it requires a new DLT_
value
On Linux, scan /sys/class/net for devices if we have it; scan
it, or /proc/net/dev if we don't have /sys/class/net, even if
we have getifaddrs(), as it'll find interfaces with no
addresses
Add limited support for reading pcap-ng files
Fix BPF driver-loading error handling on AIX
Support getting the full-length interface description on FreeBSD
In the lexical analyzer, free up any addrinfo structure we got back
from getaddrinfo().
Add support for BPF and libdlpi in OpenSolaris (and SXCE)
Hyphenate "link-layer" everywhere
Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
In pcap_read_linux_mmap(), if there are no frames available, call
poll() even if we're in non-blocking mode, so we pick up
errors, and check for the errors in question.
Note that poll() works on BPF devices is Snow Leopard
If an ENXIO or ENETDOWN is received, it may mean the device has
gone away. Deal with it.
For BPF, raise the default capture buffer size to from 32k to 512k
Support ps_ifdrop on Linux
Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile
under cygwin.
Changes to Linux mmapped captures.
Fix bug where create_ring would fail for particular snaplen and
buffer size combinations
Update pcap-config so that it handles libpcap requiring
additional libraries
Add workaround for threadsafeness on Windows
Add missing mapping for DLT_ENC <-> LINKTYPE_ENC
DLT: Add DLT_CAN_SOCKETCAN
DLT: Add Solaris ipnet
Don't check for DLT_IPNET if it's not defined
Add link-layer types for Fibre Channel FC-2
Add link-layer types for Wireless HART
Add link-layer types for AOS
Add link-layer types for DECT
Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
Install headers unconditionally, and include vlan.h/bluetooth.h if
enabled
Autoconf fixes+cleanup
Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)
Support disabling SITA support (--without-sita)
Return -1 on failure to create packet ring (if supported but
creation failed)
Fix handling of 'any' device, so that it can be opened, and no longer
attempt to open it in Monitor mode
Add support for snapshot length for USB Memory-Mapped Interface
Fix configure and build on recent Linux kernels
Fix memory-mapped Linux capture to support pcap_next() and
pcap_next_ex()
Fixes for Linux USB capture

Support for memory-mapped capture on Linux
Support for zerocopy BPF on platforms that support it

Support for setting monitor mode when opening 802.11 devices
Better support for dealing with VLAN tagging/stripping on Linux
Fix dynamic library support on OSX
Return PCAP_ERROR_IFACE_NOT_UP if the interface isn't 'UP', so applications
can print better diagnostic information
Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
applications can tell the user they need to go play with permissions
On Linux, ignore ENETDOWN so we can continue to capture packets if the
interface goes down and comes back up again.
On Linux, support new tpacket frame headers (2.6.27+)
On Mac OS X, add scripts for changing permissions on /dev/bpf* and launchd plist
On Solaris, support 'passive mode' on systems that support it
Fixes to autoconf and general build environment
Man page reorganization + cleanup
Autogenerate VERSION numbers better

Change build process to put public libpcap headers into pcap subir

".so" shared library
Add support for autoconf 2.60
Fixes to discard unread packets when changing filters
Changes to handle name changes in the DAG library resulting from
switching to libtool.
Add support for new DAG ERF types.

library dependency is explicit.
Mac OSX fixes for dealing with "wlt" devices
Fixes in add_or_find_if() & pcap_findalldevs() to optimize generating
device lists

Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
New Linux libpcap implementation, which, in 2.2 and later
kernels, uses PF_PACKET sockets and supports kernel packet
filtering (if compiled into the kernel), and supports the "any"
device for capturing on all interfaces. Cleans up promiscuous
mode better on pre-2.2 kernels, and has various other fixes
(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
doesn't show duplicate packets on loopback interface, etc.).
Fixed HP-UX libpcap implementation to correctly get the PPA for
an interface, to allow interfaces to be opened by interface name.
libpcap savefiles have system-independent link-layer type values
in the header, rather than sometimes platform-dependent DLT_
values, to make it easier to exchange capture files between
different OSes.
Non-standard capture files produced by some Linux tcpdumps, e.g.
the one from Red Hat Linux 6.2 and later, can now be read.
Updated autoconf stock files.
Filter expressions can filter on VLAN IDs and various OSI
protocols, and work on Token Ring (with non-source-routed
packets).
"pcap_open_dead()" added to allow compiling filter expressions
to pcap code without opening a capture device or capture file.
Header files fixed to allow use in C++ programs.
Removed dependancy on native headers for packet layout.
Removed Linux specific headers that were shipped.
Security fixes: Strcpy replaced with strlcpy, sprintf replaced
with snprintf.
Fixed bug that could cause subsequent "pcap_compile()"s to fail
erroneously after one compile failed.
Assorted other bug fixes.
README.aix and README.linux files added to describe
platform-specific issues.
"getifaddrs()" rather than SIOCGIFCONF used, if available.

with the same numeric value.
Assar Westerlund <assar@sics.se>
- Building outside the source code tree fixed.
- Changed to write out time stamps with 32-bit seconds and microseconds
fields, regardless of whether those fields are 32 bits or 64 bits in
the OS's native "struct timeval".
- Changed "pcap_lookupdev()" to dynamically grow the buffer into which
the list of interfaces is read as necessary in order to hold the
entire list.
Greg Troxel <gdt@ir.bbn.com>
- Added a new "pcap_compile_nopcap()", which lets you compile a filter
expression into a BPF program without having an open live capture or
capture file.

supply any "link layer" data.
- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type.

timeouts.
- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
for "lo" followed by an eos or digit (newer versions of Linux
apparently call the loopback "lo" instead of "lo0").
- Fixed Linux networking include files to use ints instead of longs to
avoid problems with 64 bit longs on the alpha. Thanks to Cristian
Gafton (gafton@redhat.com)

comparison operators, while the code generator and optimizer assumed
signed semantics in several places. Thanks to Charlie Slater

- Removed FDDI ifdef's, they aren't really needed. Resulted from report
by Gary Veum (veum@boa.gsfc.nasa.gov).
