c3674ba31c Sigh. We really *do* have to check whether a capture is a snoop or
Surveyor capture, as there's one link-layer type that UNICOS/mp snoop
treats one way and Shomiti Surveyor treats another way.  The only way to
check that is to look at the first record to see how much padding it
has.

44d19627ef From Graeme Hewson:
Allow "-" as the output file name in Wiretap, referring to the
	standard error.

	Optimize the capture loop.

Fix some of the error-message printing code in Ethereal and Tethereal.

Have Wiretap check whether it can seek on a file descriptor, and pass
the results of that test to the file-type-specific "open for output"
routine.  Have the "open for output" routines for files where we need to
seek when writing the file return an error if seeks don't work.

2aad75bb82 Graeme Hewson noted that zlib has a bug wherein "gzseek()" doesn't set
the internal z_err value for the stream if an "fseek()" call it makes
fails, so that if "gzerror()" is subsequently called, it returns Z_OK
rather than an error.

To work around this, we pass "file_seek()" an "int *err", and have the
with-zlib version of "file_seek()" check, if "gzseek()" fails, whether
the return value of "file_error()" is 0 and, if so, have it return
"errno" instead.

7da9451781 Capture file formats that can be written need a "short name" to let you
specify them on the command line of Tethereal/editcap/etc. (and to keep
those programs from dropping core when enumerating the names); now that
we can write Windows Sniffer 2.00x-format files, give them a short name.

e300f4db52 Have "wtap_seek_read()" return 0 on success and -1 on failure, and take
an "err" argument that points to an "int" into which to put an error
code if it fails.

Check for errors in one call to it, and note that we should do so in
other places.

In the "wtap_seek_read()" call in the TCP graphing code, don't overwrite
"cfile.pseudo_header", and make the buffer into which we read the data
WTAP_MAX_PACKET_SIZE bytes, as it should be.

In some of the file readers for text files, check for errors from the
"parse the record header" and "parse the hex dump" routines when reading
sequentially.

In "csids_seek_read()", fix some calls to "file_error()" to check the
error on the random stream (that being what we're reading).

d54bd0bd6b Check for errors in seeks, "tell"s, and "stat()"s/"fstat()"s.
For file types where we allocate private data, add "close" routines
where they were missing, to free the private data.  Also fix up the code
to clean up after some errors by freeing private data where that wasn't
being done.

Get rid of unused arguments to "wtap_dump_open_finish()".

non-existent functions.

particular capture file types - the argument value is implicit, in that
the routine being called is the routine for that particular file type.

0a979b81b8 Get rid of "m"/"M" and other Macintosh references in names - it appears
that EtherPeek for Windows uses the same format as EtherPeek for MacOS,
so the code isn't specific to the MacOS version.

Check the physMedium value in the secondary header, and leave a
placeholder for a value of 1, which is presumably used in AiroPeek
captures.

Treat unknown mediaType and physMedium values as indications that we
don't have a *Peek file, not as unsupported *Peek files - we need all
the heuristics we can get.

files to get that big.

From Thomas Wittwer and Matthias Nyffenegger:

Support for "ring buffer mode", wherein there's a ring buffer of N
capture files; as each capture file reaches its maximum size (the ring
buffer works only with a maximum capture file size specified), Ethereal
rolls over to the next capture file in the ring buffer, replacing
whatever packets might be in it with new packets.

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.)

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.

a251addb63 Obliging every capture file reader's "open()" routine to seek to the
beginning of the file before reading anything from the file is bogus -
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.)

Set "wth->data_offset" to 0 while you're at it, so capture file readers
don't have to do that, either.

(We really need to put in some rudimentary 64-bit integer support, for
the benefit of platforms+compilers that don't support it; the
floating-point calculations we're doing now appear not to get exactly
the right answer, from an experiment at reading a NetMon 2.x file and
writing it back out as NetMon 2.x with editcap.)

6a480953a9 Miscellaneous code cleaning
- add <stdarg.h> or <varargs.h> in snprintf.h
  and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes

- remove the check of multiple inclusions in source (.c)  code
  (there is a bit loss of _cpp_ performance, but I prefer the gain of
   code reading and maintenance; and nowadays, disk caches and VM are
   correctly optimized ;-).

- protect all (well almost) header files against multiple inclusions

- add header (i.e. GPL license) in some include files

- reorganize a bit the way header files are included:

  First:
  #include <system_include_files>
  #include <external_package_include_files (e.g. gtk, glib etc.)>
  Then
  #include "ethereal_include_files"

  with the correct HAVE_XXX or NEED_XXX protections.

- add some HAVE_XXX checks before including some system header files

- add the same HAVE_XXX in wiretap as in ethereal

Please forgive me, if I break something (I've only compiled and regression
tested on Linux).

a459c2bea7 It appears that, at least with Visual C++ 6.0, the "stat()" supplied in
the C run-time library sets "statb.st_mode" appropriately, at least for
plain files and directories; it just doesn't offer the POSIX "S_ISxxx()"
macros to test the file type.

If those macros aren't defined (which might also be the case on really
ancient UNIX systems), define them appropriately, and use them even on
Win32 systems, so that we can properly report attempts by a user to read
from a directory on Win32, just as we do on UNIX.

7de3b988bd In the final scene of the horror movie, just when you think the monster
is finally dead, and you're walking away, it springs up again and
attacks.

It appears that the ss990915 version of Alexey Kuznetzov's libpcap patch
has some extra stuff in the per-packet header for some sort of SMP
debugging, and that SuSE Linux 6.3 picked it up.

Thus, even if a libpcap file has the modified magic number, we *still*
have to go through the usual heuristic hell to figure out what type of
file it is.

e068b7dbe7 In Tethereal:
When capturing, report errors trying to create the output file
	with "file_open_error_message()".

	Make the "for_writing" argument to "file_open_error_message()" a
	"gboolean", as it's either TRUE (if the file is being opened for
	writing) or FALSE (if it's being opened for reading).

	Report EISDIR as "XXX is a directory (folder), not a file.".

When checking whether an "open()" of a capture file succeeded, check
whether "open()" returns a negative number, not whether it returns 0.

In "wtap_open_offline()", if the file to be opened is a directory,
return EISDIR, not WTAP_ERR_NOT_REGULAR_FILE, so that the error message
can say "that's a directory, not a file".

If "wtap_open_offline()" returns WTAP_ERR_NOT_REGULAR_FILE, don't just
say the file is "invalid", say it's a "special file" or socket or some
other weird type of file.

f3d90d30a4 Remove the "union pseudo_header" from the "frame_data" structure;
there's no need to keep it around in memory - when the frame data is
read in when handing a frame, read in the information, if any, necessary
to reconstruct the frame header, and reconstruct it.  This saves some
memory.

This requires that the seek-and-read function be implemented inside
Wiretap, and that the Wiretap handle remain open even after we've
finished reading the file sequentially.

This also points out that we can't really do X.25-over-Ethernet
correctly, as we don't know where the direction (DTE->DCE or DCE->DTE)
flag is stored; it's not clear how the Ethernet type 0x0805 for X.25
Layer 3 is supposed to be handled in any case.  We eliminate
X.25-over-Ethernet support (until we find out what we're supposed to
do).
