Merge remote-tracking branch 'goog/tcpdump'
* goog/tcpdump: (1872 commits)
Remove old version. Getting ready for new libpcap 1.5
Remove commas from clauses in a comma-separated list.
Fix typo.
Describe all NFLOG TLV types and define structures for some of them.
Check caplen in the NFLOG TLV loop.
Have nflog_tlv_t include only the TLV header.
Byte-swap the T and L in TLVs as necessary when reading an NFLOG file.
Don't support D-Bus sniffing on OS X.
Add post-1.5.2 bug fixes.
Tag some changes with a bug identifier.
Add items for 1.5.1 and 1.5.2.
Formatting tweak.
Count *ring buffer blocks*, not *packets* to be filtered in userland.
Add a PACKET_COUNT_IS_UNLIMITED() to test for a packet count <= 0.
Use HAVE_TPACKET3 rather than TPACKET_V3 to test for TPACKET_V3 support.
Fix builds on systems without TPACKET_V3.
tweak manpages formatting
Fix pcap_loop() with a count of 0 and TPACKET_V3.
Discourage the use of a zero timeout.
We can't use TPACKET_V3 in immediate mode, so fall back on TPACKET_V2.

+libpcap for DOS
+---------------
+
+This file contains some notes on building and using libpcap for MS-DOS.
+Look in `README' and `pcap.man' for usage and details. These targets are
+supported:
+
+ - Borland C 4.0+ small or large model.
+ - Metaware HighC 3.1+ with PharLap DOS-extender
+ - GNU C 2.7+ with djgpp 2.01+ DOS extender
+ - Watcom C 11.x with DOS4GW extender
+
+Note: the files in the libpcap.zip contains short trucated filenames.
+ So for djgpp to work with these, disable the use of long file names by
+ setting "LFN=n" in the environment.
+
+Files specific to DOS are pcap-dos.[ch] and the assembly and C files in
+the MSDOS sub-directory. Remember to built lipcap libraries from the top
+install directory. And not from the MSDOS sub-directory.
+
+Note for djgpp users:
+ If you got the libpcap from the official site www.tcpdump, then that
+ distribution does NOT contain any sources for building 32-bit drivers.
+ Instead get the full version at
+ http://www.bgnett.no/~giva/pcap/libpcap.zip
+
+ and set "USE_32BIT_DRIVERS = 1" in msdos\common.dj.
+
+
+
+Requirements
+------------
+
+DOS-libpcap currently only works reliably with a real-mode Ethernet packet-
+driver. This driver must be installed prior to using any program (e.g.
+tcpdump) compiled with libpcap. Work is underway to implement protected-
+mode drivers for 32-bit targets (djgpp only). The 3Com 3c509 driver is
+working almost perfectly. Due to lack of LAN-cards, I've not had the
+opportunity to test other drivers. These 32-bit drivers are modified
+Linux drivers.
+
+
+Required packages
+-----------------
+
+The following packages and tools must be present for all targets.
+
+1. Watt-32 tcp/ip library. This library is *not* used to send or
+ receive network data. It's mostly used to access the 'hosts'
+ file and other <netdb.h> features. Get 'watt32s*.zip' at:
+
+ http://www.bgnett.no/~giva/
+
+2. Exception handler and disassember library (libexc.a) is needed if
+ "USE_EXCEPT = 1" in common.dj. Available at:
+
+ http://www.bgnett.no/~giva/misc/exc_dx07.zip
+
+3. Flex & Bison is used to generate parser for the filter handler
+ pcap_compile:
+
+ ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/flx254b.zip
+ ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsn128b.zip
+
+4. NASM assembler v 0.98 or later is required when building djgpp and
+ Watcom targets:
+
+ ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2tk/nasm098p.zip
+
+5. sed (Stream Editor) is required for doing `make depend'.
+ It's available at
+ ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/sed*.zip
+
+ A touch tool to update the time-stamp of a file. E.g.
+ ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/grep*.zip
+
+6. For djgpp rm.exe and cp.exe are required. These should already be
+ part of your djgpp installation. Also required (experimental at the
+ time) for djgpp is DLX 2.91 or later. This tool is for the generation
+ of dynamically loadable modules.
+
+
+Compiling libpcap
+-----------------
+
+Follow these steps in building libpcap:
+
+1. Make sure you've installed Watt-32 properly (see it's `INSTALL' file).
+ During that installation a environment variable `WATT_ROOT' is set.
+ This variable is used for building libpcap also (`WATT_INC' is
+ deducted from `WATT_ROOT'). djgpp users should also define environment
+ variables `C_INCLUDE_PATH' and `LIBRARY_PATH' to point to the include
+ directory and library directory respectively. E.g. put this in your
+ AUTOEXEC.BAT:
+ set C_INCLUDE_PATH=c:/net/watt/inc
+ set LIBRARY_PATH=c:/net/watt/lib
+
+2. Revise the msdos/common.dj file for your djgpp/gcc installation;
+ - change the value of `GCCLIB' to match location of libgcc.a.
+ - set `USE_32BIT_DRIVERS = 1' to build 32-bit driver objects.
+
+
+3. Build pcap by using appropriate makefile. For djgpp, use:
+ `make -f msdos/makefile.dj' (i.e. GNU `make')
+
+ For a Watcom target say:
+ `wmake -f msdos\makefile.wc'
+
+ For a Borland target say:
+ `maker -f msdos\Makefile pcap_bc.lib' (Borland's `maker.exe')
+
+ And for a HighC/Pharlap target say:
+ `maker -f msdos\Makefile pcap_hc.lib' (Borland's `maker.exe')
+
+ You might like to change some `CFLAGS' -- only `DEBUG' define currently
+ have any effect. It shows a rotating "fan" in upper right corner of
+ screen. Remove `DEBUG' if you don't like it. You could add
+ `-fomit-frame-pointer' to `CFLAGS' to speed up the generated code.
+ But note, this makes debugging and crash-traceback difficult. Only
+ add it if you're fully confident your application is 100% stable.
+
+ Note: Code in `USE_NDIS2' does not work at the moment.
+
+4. The resulting libraries are put in current directory. There's no
+ test-program for `libpcap'. Linking the library with `tcpdump' is
+ the ultimate test anyway.
+
+
+
+Extensions to libpcap
+---------------------
+
+I've included some extra functions to DOS-libpcap:
+
+ `pcap_config_hook (const char *name, const char *value)'
+
+ Allows an application to set values of internal libpcap variables.
+ `name' is typically a left-side keyword with an associated `value'
+ that is called from application's configure process (see tcpdump's
+ config.c file). libpcap keeps a set of tables that are searched for
+ a name/value match. Currently only used to set debug-levels and
+ parameters for the 32-bit network drivers.
+
+ `pcap_set_wait (pcap_t *, void (*)(void), int)' :
+
+ Only effective when reading offline traffic from dump-files.
+ Function `pcap_offline_read()' will wait (and optionally yield)
+ before printing next packet. This will simulate the pace the packets
+ where actually recorded.
+
+
+
+Happy sniffing !
