Guy Harris a7bb49b0d9 Add support for LocalTalk Link Access Protocol.
Rename WTAP_ENCAP_PRISM to WTAP_ENCAP_PRISM_HEADER, to match
DLT_PRISM_HEADER.

Add in missing capture support for WTAP_ENCAP_PRISM_HEADER when
capturing with "pcap_open_live()" rather than reading the capture from a
pipe.

Guy Harris 16bb4350ff Back the previous hack out - the padding is often zero, but it's not
*always* zero, so it won't always work, and it's somewhat gross.  The
right answer is "don't use Digital/Tru64 UNIX's tcpdump, use
tcpdump.org's".

Guy Harris 40b22f317b Wrap calls to "pcap_datalink()" in a routine that attempts to compensate
for AIX 5.x's non-standard libpcap, where "pcap_datalink()" doesn't
return DLT_ values, it returns RFC 1573 ifType values.

Put that wrapper, and the routine to get the interface list, in a
separate file, for packet-capture utility routines, so not everybody who
includes "util.h" needs to include <pcap.h>.

Fix up the Wiretap hack for dealing with said incompatibility to use the
correct ifType value for Token Ring.

Guy Harris b7d32da1eb Expand on the comments about AIX libpcap.
No, Nokia *weren't* kind enough to change the major or minor version
number in the capture file when they changed the format, just as they
weren't kind enough to change the magic number.

Guy Harris 6910b84deb Add in some heuristics to try to detect AIX libpcap format. (This works
with one capture I've seen, but perhaps that was done with an old
version of AIX, and newer versions use a minor version number, in the
file, of 4.

However, libpcap hasn't used a minor version of 2 for ages, so perhaps
AIX hasn't updated their libpcap in ages, and aren't about to do so
soon.  If they do, let's hope they change the magic number.  The capture
file in question *does* have the capture length and real length in the
old, pre-2.3, order, so it really looks as if it's an old version,
rather than IBM trying to be "helpful" by using a different minor
version number so that you can distinguish between normal libpcap and
AIX libpcap formats.)

Guy Harris f509ddeaa5 Don't create a Wiretap dump file unless we're at least sure we support
the specified encapsulation with the specified capture file type, and
that we can allocate a "wtap_dumper *".

If we could do all that, and could create the dump file, but the
file-type-specific create routine fails (e.g., because there's not
enough disk space to write out the header), remove the dump file.

Guy Harris 837e848329 Sigh. Shomiti apparently didn't know that the RFC 1761 data link types
were just DLPI data link types, and didn't know that the list had
expanded at some point and that Sun *used* some of the new types (e.g.,
in atmsnoop), or decided on their own to go beyond those types to encode
an Oh-So-Useful link speed indication, or just didn't *care* that they
were just DLPI data link types.

Therefore, we have to map Shomiti link types to wiretap types using a
different mapping table.  For now, we assume files with a version number
of 2 are snoop files, and version numbers of 3, 4, and 5 are Shomiti
files; Shomiti claims to use a version number of 2 as well, but to
determine whether a file with a version number of 2 is a snoop file or a
Shomiti file requires that we look at the header of the first packet and
assume that if there's more than 3 bytes of padding it's a Shomiti file.

The return value from "fwrite()" is a "size_t"; make the variable into
which we store it a "size_t", and then fix up the bugs that were
revealed by the compiler warnings that produced - "fwrite()" returns 0,
not a negative number, on an I/O error.

Guy Harris 4533ae7c55 If there's no "zlib.h" header, we won't be using zlib, so don't bother
checking for "gzgets()" in zlib.

If there is a "zlib.h" header, and there is a "gzgets()" in zlib, check
whether we find "gzgets()" in zlib when we link with the GTK+ link
flags, and, if not, fail.  People often grab XFree86 source and build
and install it on their systems, and they appear sometimes to
misconfigure XFree86 so that, even on systems with zlib, it assumes
there is no zlib, so the XFree86 build process builds and installs its
own "mini-zlib" in the X11 library directory.  The "mini-zlib" lacks
"gzgets()", and that's the zlib with which Ethereal gets linked, so the
build of Ethereal fails.

Guy Harris 5bb08b0970 Fix AC_ETHEREAL_PCAP_CHECK so that, if a directory was specified with
"--with-pcap", it adds the "include" subdirectory of that directory to
the list of directories to search for include files, rather than adding
the directory itself.

Check whether libpcap defines "pcap_version", and define
HAVE_PCAP_VERSION if it does.  Use "pcap_version" iff HAVE_PCAP_VERSION
is defined, rather than special-casing MacOS X.

Don't #define a string for the WinPcap version; just leave
HAVE_PCAP_VERSION undefined on Windows, as WinPcap 2.2beta is out, so we
can no longer assume that the Windows version of Ethereal is using
WinPcap 2.1.

replace "--with-plugindir" with "--with-plugins", and have the
	plugin directory optional - this allows plugins to be disabled;

	add "--traditional-cpp" on MacOS X/Darwin (Apple's "cc" compiler
	requires it, for some annoying reason, even though it is, as far
	as I know, GCC-based, and other GCC's don't require it);

	on MacOS X, don't use "pcap_version[]", as, for some annoying
	reason, libpcap on MacOS X doesn't define it.

Clean up some whitespace in the help messages for the configure script.

Move the AM_CONDITIONAL for SETUID_INSTALL after the point at which
"enable_setuid_install" is set, as it tests "enable_setuid_install".

Guy Harris 537d308abe "open_cap_file()" in Ethereal and Tethereal don't use the FILE_T they
get from calling "wtap_file()", so get rid of the call and the
(otherwise unused) variable to which its result gets assigned.

That lets us get rid of "wtap_file()" in Wiretap.

It also lets us get rid of the include of "zlib.h" in "file.h"; the
#defines of "file_open()", "filed_open()", and "file_close()" are also
unnecessary, so we get rid of those as well.

However, that means we need to include <zlib.h> in "gtk/main.c" and
"tethereal.c", so that the version number of libz is defined and can
show up in the version string.

Guy Harris 3782799323 As of GLib 1.2.9, you won't automatically get "-I/usr/local/include" and
"-L/usr/local/lib" added to CFLAGS and LDFLAGS merely as a result of
running AM_PATH_GLIB, as 1.2.9 and later don't install headers directly
under "/usr/local/include".  Therefore, we have to put
"-I/usr/local/include" into CFLAGS ourselves, just as we do in the
top-level configure script, or we run the risk of not being able to find
other packages (libpcap, zlib, etc.) if it's installed under
"/usr/local".

Guy Harris aedaabc8c8 GCC 2.95.1 on SPARC/Solaris, at least, is clever enough to figure out
that the loop in "lanalyzer_open()" is an infinite loop, so the "return
0;" at the end isn't necessary to suppress a compiler warning with that
compiler - and Sun C not only figures it out, it warns that the
"g_assert_not_reached()" and the "return 0;" are unreachable, so I'll
take them out for now (and put them back if my older GCC at home still
requires it to suppress warnings).

and

	2) MSVC appears to treat structures as requiring 8-byte

(they're *almost* the same as Ethernet types, but 0x8035 is SLARP, not
Reverse ARP, and 0x2000 is the Cisco Discovery protocol, for example),
replacing "fr.chdlc".

Have a "chdlctype()" routine, similar to "ethertype()", used both by the
Cisco HDLC and Frame Relay dissectors.  Have a "chdlc_vals[]"
"value_string" table for Cisco HDLC types and protocol names.  Split the

Guy Harris a251addb63 Obliging every capture file reader's "open()" routine to seek to the

do that in the loop that tries each of the open routines, instead.
(They may have to reset the seek pointer later if, for example, the
capture file begins with the first packet, and the "open()" routine
looks at that packet to try to guess whether the packet is in the file
format in question.)
