Summary for 1.8.1 libpcap release
Add a target in Makefile.in for Exuberant Ctags use: 'extags'.
Rename configure.in to configure.ac: autoconf 2.59
Clean up the name-to-DLT mapping table.
Add some newer DLT_ values: IPMI_HPM_2,ZWAVE_R1_R2,ZWAVE_R3,WATTSTOPPER_DLM,ISO_14443,RDS
Clarify what the return values are for both success and failure.
Many changes to build on windows
Check for the "break the loop" condition in the inner loop for TPACKET_V3.
Fix handling of packet count in the TPACKET_V3 inner loop: GitHub issue #493.
Filter out duplicate looped back CAN frames.
Fix the handling of loopback filters for IPv6 packets.
Add a link-layer header type for RDS (IEC 62106) groups.
Use different intermediate folders for x86 and x64 builds on Windows.
On Linux, handle all CAN captures with pcap-linux.c, in cooked mode.
Removes the need for the "host-endian" link-layer header type.
Compile with '-Wused-but-marked-unused' in devel mode if supported
Have separate DLTs for big-endian and host-endian SocketCAN headers.
Reflect version.h being renamed to pcap_version.h.
Require that version.h be generated: all build procedures we support generate version.h (autoconf, CMake, MSVC)!

@ -31,40 +31,22 @@ You will need an ANSI C compiler to build libpcap. The configure script
will abort if your compiler is not ANSI compliant. If this happens, use
the generally available GNU C compiler (GCC).
If you use flex, you must use version 2.4.6 or higher. The configure
script automatically detects the version of flex and will not use it
unless it is new enough. You can use "flex -V" to see what version you
have (unless it's really old). The current version of flex is available
at flex.sourceforge.net and often comes packaged by means of the OS.
As of this writing, the current version is 2.5.37.
You will need either Flex 2.5.31 or later, or a version of Lex
compatible with it (if any exist), to build libpcap. The configure
script will abort if there isn't any such program. If you have an older
version of Flex, or don't have a compatible version of Lex, the current
version of flex is available at flex.sourceforge.net.
If you use bison, you must use flex (and visa versa). The configure
script automatically falls back to lex and yacc if both flex and bison
are not found.
You will need either Bison, Berkeley YACC, or a version of YACC
compatible with them (if any exist), to build libpcap. The configure
script will abort if there isn't any such program. If you don't have
any such program, the current version of Bison can be found at
http://ftp.gnu.org/gnu/bison/ and the current version of Berkeley YACC
can be found at http://invisible-island.net/byacc/.
Sometimes the stock C compiler does not interact well with flex and
bison. The list of problems includes undefined references for alloca.
You can get around this by installing gcc or manually disabling flex
and bison with:
./configure --without-flex --without-bison
If your system only has AT&T lex, this is okay unless your libpcap
program uses other lex/yacc generated code. (Although it's possible to
map the yy* identifiers with a script, we use flex and bison so we
don't feel this is necessary.)
Some systems support the Berkeley Packet Filter natively; for example
out of the box OSF and BSD/OS have bpf. If your system does not support
bpf, you will need to pick up:
ftp://ftp.ee.lbl.gov/bpf-*.tar.Z
Note well: you MUST have kernel source for your operating system in
order to install bpf. An exception is SunOS 4; the bpf distribution
includes replacement kernel objects for some of the standard SunOS 4
network device drivers. See the bpf INSTALL document for more
information.

* This is a GCC-compatible compiler and we have __attribute__, which
* we assume that mean we have __attribute__((packed)), and this is
* MIPS or Alpha, which has instructions that can help when doing
* unaligned loads.
*
* Declare packed structures containing a uint16_t and a uint32_t,
* cast the pointer to point to one of those, and fetch through it;
* the GCC manual doesn't appear to explicitly say that
* __attribute__((packed)) causes the compiler to generate unaligned-safe
* code, but it apppears to do so.
*
* We do this in case the compiler can generate code using those
* instructions to do an unaligned load and pass stuff to "ntohs()" or
* "ntohl()", which might be better than than the code to fetch the
* bytes one at a time and assemble them. (That might not be the
* case on a little-endian platform, such as DEC's MIPS machines and
* Alpha machines, where "ntohs()" and "ntohl()" might not be done
* inline.)
*
* We do this only for specific architectures because, for example,
* at least some versions of GCC, when compiling for 64-bit SPARC,
* generate code that assumes alignment if we do this.
*
* XXX - add other architectures and compilers as possible and
* appropriate.
*
* HP's C compiler, indicated by __HP_cc being defined, supports
* "#pragma unaligned N" in version A.05.50 and later, where "N"
* specifies a number of bytes at which the typedef on the next
* line is aligned, e.g.
*
* #pragma unalign 1
* typedef uint16_t unaligned_uint16_t;
*
* to define unaligned_uint16_t as a 16-bit unaligned data type.
* This could be presumably used, in sufficiently recent versions of
* the compiler, with macros similar to those below. This would be
* useful only if that compiler could generate better code for PA-RISC
* or Itanium than would be generated by a bunch of shifts-and-ORs.
*
* DEC C, indicated by __DECC being defined, has, at least on Alpha,
* an __unaligned qualifier that can be applied to pointers to get the
* compiler to generate code that does unaligned loads and stores when
* dereferencing the pointer in question.
*
* XXX - what if the native C compiler doesn't support
* __attribute__((packed))? How can we get it to generate unaligned
* accesses for *specific* items?

* 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.

* a separate "monitor mode" device for each wireless
* adapter, rather than by implementing the ioctls
* that {Free,Net,Open,DragonFly}BSD provide.

* they're associated.

*
* We use void * rather than yyscan_t because, at least with some
* versions of Flex and Bison, if you use yyscan_t in %parse-param and
* %lex-param, you have to include scanner.h before grammar.h to get
* yyscan_t declared, and you have to include grammar.h before scanner.h
* to get YYSTYPE declared. Using void * breaks the cycle; the Flex
* documentation says yyscan_t is just a void *.

* - TotDrops: the amount of packet that were dropped into the kernel buffer because of lack of space

* the value of the hardware counter into the card. This number is never put to zero, so this number
* takes into account the *total* number of interface drops starting from the interface power-on.
* - OrigMissed: the amount of packets that were dropped by the interface *when the capture begins*.

* packets in flight, i.e. that have been transmitted by the remote host, but that have not been
* received (yet) from the client. In this case, (TotAccepted - TotDrops - TotNetDrops) gives a

.RE
.LP
By default, when performing a live capture or reading from a savefile,
time stamps are supplied as seconds since January 1, 1970, 00:00:00 UTC,
and microseconds since that seconds value, even if higher-resolution
time stamps are available from the capture device or in the savefile.
If, when reading a savefile, the time stamps in the file have a higher
resolution than one microsecond, the additional digits of resolution are
discarded.
.LP
The
.BR pcap_set_tstamp_precision (3PCAP)
routine can be used after a
.B pcap_create()
call and after a
.B pcap_activate()
call to specify the resolution of the time stamps to get for the device.
If the hardware or software cannot supply a higher-resolution time
stamp, the
.B pcap_set_tstamp_precision()
call will fail, and the time stamps supplied after the
.B pcap_activate()
call will have microsecond resolution.
.LP
When opening a savefile, the
.BR pcap_open_offline_with_tstamp_precision (3PCAP)
and
.BR pcap_fopen_offline_with_tstamp_precision (3PCAP)
routines can be used to specify the resolution of time stamps to be read
from the file; if the time stamps in the file have a lower resolution,
the fraction-of-a-second portion of the time stamps will be scaled to
the specified resolution.
.LP
The
.BR pcap_get_tstamp_precision (3PCAP)
routine returns the resolution of time stamps that will be supplied;
when capturing packets, this does not reflect the actual precision of
the time stamp supplied by the hardware or operating system and, when
reading a savefile, this does not indicate the actual precision of time
stamps in the file.
