# Nmap Changelog ($Id$); -*-text-*-
o Upgraded the included libpcap to version 1.1.1. [David]
o [NSE] Add some special use IPv4 addresses to isPrivate which are described in
RFC 5736 and RFC 5737, published in Jan 2010. Improve performance of isPrivate
for IPv4 addresses by using ip_in_range less frequently. Add an extra return

@(#) $Header: /tcpdump/master/libpcap/CHANGES,v 1.67.2.4 2008-10-28 00:27:42 ken Exp $ (LBL)
Thu. April 1, 2010. guy@alum.mit.edu.
Summary for 1.1.1 libpcap release
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
DLT: Add DLT_LINUX_EVDEV
DLT: Add DLT_GSMTAP_UM
DLT: Add DLT_GSMTAP_ABIS

On Linux, ignore ENETDOWN so we can continue to capture packets if the

If unsure, say N.
Note that, by default, libpcap will, if libnl is present, build with it;
it uses libnl to support monitor mode on mac80211 devices. There is a
configuration option to disable building with libnl, but, if that option
is chosen, the monitor-mode APIs (as used by tcpdump's "-I" flag, and as
will probably be used by other applications in the future) won't work
properly on mac80211 devices.
Linux's run-time linker allows shared libraries to be linked with other
shared libraries, which means that if an older version of a shared
library doesn't require routines from some other shared library, and a
later version of the shared library does require those routines, the
later version of the shared library can be linked with that other shared
library and, if it's otherwise binary-compatible with the older version,
can replace that older version without breaking applications built with
the older version, and without breaking configure scripts or the build
procedure for applications whose configure script doesn't use the
pcap-config script if they build with the shared library. (The build
procedure for applications whose configure scripts use the pcap-config
script if present will not break even if they build with the static
library.)

.B \-L
and

linker required to link with libpcap, including
linker flags required to link with libpcap, including
.B \-l
flags for libraries required by libpcap.
When run with the
.B \-\-additional-libs
option,
.I pcap-config
writes to the standard output the
.B \-L
and
.B \-l
flags for libraries required by libpcap, but not the
.B \-lpcap
flag to link with libpcap itself.
.LP
By default, it writes flags appropriate for compiling with a
dynamically-linked version of libpcap; the
.B \-\-static
flag causes it to write flags appropriate for compiling with a
statically-linked version of libpcap.

* dli_version is 2 for the current version of the pseudo-header.
*
* dli_family is a Solaris address family value, so it's 2 for IPv4
* and 26 for IPv6.
*
* dli_htype is a "hook type" - 0 for incoming packets, 1 for outgoing
* packets, and 2 for packets arriving from another zone on the same
* machine.
*
* dli_pktlen is the length of the packet data following the pseudo-header
* (so the captured length minus dli_pktlen is the length of the
* pseudo-header, assuming the entire pseudo-header was captured).
*
* dli_ifindex is the interface index of the interface on which the
* packet arrived.
*
* dli_grifindex is the group interface index number (for IPMP interfaces).
*
* dli_zsrc is the zone identifier for the source of the packet.
*
* dli_zdst is the zone identifier for the destination of the packet.
*
* A zone number of 0 is the global zone; a zone number of 0xffffffff
* means that the packet arrived from another host on the network, not
* from another zone on the same machine.
*
* An IPv4 or IPv6 datagram follows the pseudo-header; dli_family indicates
* which of those it is.
