Always return an error message for errors finding DAG or Myricom
devices
If possible, don't require that a device be openable when
enumerating them for pcap_findalldevs()
Don't put incompletely-initialized addresses in the address list for
When finding Myricom devices, update description for regular
interfaces that are Myricom devices and handle SNF_FLAGS=0x2(port
aggregation enabled)
Fix compilation error in DAG support

Guidelines for contributing
===========================
To report a security issue (segfault, buffer overflow, infinite loop, arbitrary
code execution etc) please send an e-mail to security@tcpdump.org, do not use
the bug tracker!
To report a non-security problem (failure to compile, failure to capture packets
properly, missing support for a network interface type or DLT) please check
first that it reproduces with the latest stable release of libpcap. If it does,
please check that the problem reproduces with the current git master branch of
libpcap. If it does (and it is not a security-related problem, otherwise see
above), please navigate to https://github.com/the-tcpdump-group/libpcap/issues
and check if the problem has already been reported. If it has not, please open
a new issue and provide the following details:
* libpcap version (e.g. from tcpdump --version)
* operating system name and version and any other details that may be relevant
(uname -a, compiler name and version, CPU type etc.)
* configure flags if any were used
* statement of the problem
* steps to reproduce
Please note that if you know exactly how to solve the problem and the solution
would not be too intrusive, it would be best to contribute some development time
and open a pull request instead.
Still not sure how to do? Feel free to [subscribe](http://www.tcpdump.org/#mailing-lists)
to the mailing list tcpdump-workers@lists.tcpdump.org and ask!

You must add streams NIT support to your kernel configuration, run
config and boot the new kernel.
If you are running a version of SunOS earlier than 4.1, you will need
to replace the Sun supplied /sys/sun{3,4,4c}/OBJ/nit_if.o with the
appropriate version from this distribution's SUNOS4 subdirectory and
build a new kernel:
nit_if.o.sun3-sunos4 (any flavor of sun3)
nit_if.o.sun4c-sunos4.0.3c (SS1, SS1+, IPC, SLC, etc.)
nit_if.o.sun4-sunos4 (Sun4's not covered by
nit_if.o.sun4c-sunos4.0.3c)
These nit replacements fix a bug that makes nit essentially unusable in
pre-SunOS 4.1. In addition, our sun4c-sunos4.0.3c nit gives you
timestamps to the resolution of the SS-1 clock (1 us) rather than the
lousy 20ms timestamps Sun gives you (tcpdump will print out the full
timestamp resolution if it finds it's running on a SS-1).

dnl This test is for network applications that need socket() and
dnl gethostbyname() -ish functions. Under Solaris, those applications
dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
dnl with "-lnsl" but should *not* link with "-lsocket" because
dnl libsocket.a breaks a number of things (for instance:
dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
dnl versions of IRIX).
dnl This test is for network applications that need socket functions and
dnl getaddrinfo()/getnameinfo()-ish functions. We now require
dnl getaddrinfo() and getnameinfo(). We also prefer versions of
dnl recvmsg() that conform to the Single UNIX Specification, so that we
dnl can check whether a datagram received with recvmsg() was truncated
dnl when received due to the buffer being too small.
dnl
dnl Unfortunately, many application developers are not aware of this,
dnl and mistakenly write tests that cause -lsocket to be used under
dnl IRIX. It is also easy to write tests that cause -lnsl to be used
dnl under operating systems where neither are necessary (or useful),
dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
dnl On most operating systems, they're available in the system library.
dnl
dnl This test exists so that every application developer does not test
dnl this in a different, and subtly broken fashion.
dnl It has been argued that this test should be broken up into two
dnl seperate tests, one for the resolver libraries, and one for the
dnl libraries necessary for using Sockets API. Unfortunately, the two
dnl are carefully intertwined and allowing the autoconf user to use
dnl them independantly potentially results in unfortunate ordering
dnl dependancies -- as such, such component macros would have to
dnl carefully use indirection and be aware if the other components were
dnl executed. Since other autoconf macros do not go to this trouble,
dnl and almost no applications use sockets without the resolver, this
dnl complexity has not been implemented.
dnl Under Solaris, we need to link with libsocket and libnsl to get
dnl getaddrinfo() and getnameinfo() and, if we have libxnet, we need to
dnl link with libxnet before libsocket to get a version of recvmsg()
dnl that conforms to the Single UNIX Specification.
dnl
dnl The check for libresolv is in case you are attempting to link
dnl statically and happen to have a libresolv.a lying around (and no
dnl libnsl.a).
dnl We use getaddrinfo() because we want a portable thread-safe way
dnl of getting information for a host name or port; there exist _r
dnl versions of gethostbyname() and getservbyname() on some platforms,
dnl but not on all platforms.

# PACKET_INCLUDE_DIR - absolute path to the directory containing Packet32.h.
#
# PACKET_LIBRARY - relative or absolute path to the Packet library to
# link with. An absolute path is will be used if the
# Packet library is not located in the compiler's
# default search path. See e.g. PACKET_DLL_DIR
# variable below.
# PACKET_FOUND - TRUE if the Packet library *and* header are found.
#
# Hints and Backward Compatibility
# ================================
#
# To tell this module where to look, a user may set the environment variable
# PACKET_DLL_DIR to point cmake to the *root* of a directory with include and
# lib subdirectories for packet.dll (e.g WpdPack/npcap-sdk).
# Alternatively, PACKET_DLL_DIR may also be set from cmake command line or GUI
# (e.g cmake -DPACKET_DLL_DIR=/path/to/packet [...])

# ==============================================================================
# This is a heavily modified version of FindPthreads.cmake for the pcap project.
# It's meant to find Pthreads-w32, an implementation of the
# Threads component of the POSIX 1003.1c 1995 Standard (or later)
# for Microsoft's WIndows.
#
# Apart from this notice, this module "enjoys" the following modifications:
#
# - changed its name to FindPthreads-w32.cmake to not conflict with FindThreads.cmake
#
# - users may be able to use the environment variable PTHREADS_ROOT to point
# cmake to the *root* of their Pthreads-w32 installation.
# Alternatively, PTHREADS_ROOT may also be set from cmake command line or GUI
# (-DPTHREADS_ROOT=/path/to/Pthreads-w32)
# Two other variables that can be defined in a similar fashion are
# PTHREAD_INCLUDE_PATH and PTHREAD_LIBRARY_PATH.
#
# - added some additional status/error messages
#
# - changed formating (uppercase to lowercare + indentation)
#
# - removed some stuff
#
# - when searching for Pthreads-win32 libraries, the directory structure of the
# pre-build binaries folder found in the pthreads-win32 CVS code repository is
# considered (e.i /Pre-built.2/lib/x64 /Pre-built.2/lib/x86)
#
# Send suggestion, patches, gifts and praises to pcap's developers.
# ==============================================================================
#
# Find the Pthreads library
# This module searches for the Pthreads-win32 library (including the
# pthreads-win32 port).
#
# This module defines these variables:
#
# PTHREADS_FOUND - True if the Pthreads library was found
# PTHREADS_LIBRARY - The location of the Pthreads library
# PTHREADS_INCLUDE_DIR - The include directory of the Pthreads library
# PTHREADS_DEFINITIONS - Preprocessor definitions to define (HAVE_PTHREAD_H is a fairly common one)
#
# This module responds to the PTHREADS_EXCEPTION_SCHEME
# variable on Win32 to allow the user to control the
# library linked against. The Pthreads-win32 port
# provides the ability to link against a version of the
# library with exception handling.
# IT IS NOT RECOMMENDED THAT YOU CHANGE PTHREADS_EXCEPTION_SCHEME
# TO ANYTHING OTHER THAN "C" because most POSIX thread implementations
# do not support stack unwinding.
#
# PTHREADS_EXCEPTION_SCHEME
# C = no exceptions (default)
# (NOTE: This is the default scheme on most POSIX thread
# implementations and what you should probably be using)
# CE = C++ Exception Handling
# SE = Structure Exception Handling (MSVC only)
#

# and validate user choice.

* Try to get a description for a given device.

*
* XXX - on FreeBSDs that support it, should it get the sysctl named
* "dev.{adapter family name}.{adapter unit}.%desc" to get a description
* of the adapter? Note that "dev.an.0.%desc" is "Aironet PC4500/PC4800"
* with my Cisco 350 card, so the name isn't entirely descriptive. The
* "dev.an.0.%pnpinfo" has a better description, although one might argue
* that the problem is really a driver bug - if it can find out that it's
* a Cisco 340 or 350, rather than an old Aironet card, it should use
* that in the description.
*
* Do NetBSD, DragonflyBSD, or OpenBSD support this as well? FreeBSD
* and OpenBSD let you get a description, but it's not generated by the OS,
* it's set with another ioctl that ifconfig supports; we use that to get
* a description in FreeBSD and OpenBSD, but if there is no such
* description available, it still might be nice to get some description
* string based on the device type or something such as that.
*
* In OS X, the System Configuration framework can apparently return
* names in 10.4 and later.
*
* It also appears that freedesktop.org's HAL offers an "info.product"
* string, but the HAL specification says it "should not be used in any
* UI" and "subsystem/capability specific properties" should be used
* instead and, in any case, I think HAL is being deprecated in
* favor of other stuff such as DeviceKit. DeviceKit doesn't appear
* to have any obvious product information for devices, but maybe
* I haven't looked hard enough.
*
* Using the System Configuration framework, or HAL, or DeviceKit, or
* whatever, would require that libpcap applications be linked with
* the frameworks/libraries in question. That shouldn't be a problem
* for programs linking with the shared version of libpcap (unless
* you're running on AIX - which I think is the only UN*X that doesn't
* support linking a shared library with other libraries on which it
* depends, and having an executable linked only with the first shared
* library automatically pick up the other libraries when started -
* and using HAL or whatever). Programs linked with the static
* version of libpcap would have to use pcap-config with the --static
* flag in order to get the right linker flags in order to pick up
* the additional libraries/frameworks; those programs need that anyway
* for libpcap 1.1 and beyond on Linux, as, by default, it requires
* -lnl.
*
* Do any other UN*Xes, or desktop environments support getting a
* description?
