Gerald Combs c83c84fffb Add initial support for "type 12" frames. I have no documentation for
these other than a trace file a client sent me.  The header appears to
be similar to frame2 and frame4 records, but with extra bytes at the end.
The trace file also contains record types 13 - 17 which appear to contain
metainformation such as retransmit counts.

Guy Harris 81c030d01a Wiretap no longer works with "GLib 1.0[.x]" (the version that came
bundled with GTK+ 1.0[.x]), it works only with 1.2[.x] and later, so we
no longer need to check for 1.0[.x] and define HAVE_GLIB10.

Guy Harris f881e13932 Windows Sniffers appear to write out ATM traces with a network type of
8, which is NDIS's ATM type.  At least one capture appears to have
LLC-encapsulated frames in it; for now, we'll map it to
WTAP_ENCAP_ATM_RFC1483 - and make Ethereal dissect
WTAP_ENCAP_ATM_RFC1483 by handing the frames to "dissect_llc()".

While we're at it, we'll have Ethereal panic if handed a Wiretap packet
type it doesn't dissect, rather than giving you a rather blank
dissection.

Gilbert Ramirez c312f69abc Make sure to pass the sent/received direction from pppdump.c in
pseudo_header.
Use generic "p2p_phdr" instead of "lapd_phdr". Modify toshiba.c and
packet-lapd.c to take that into account.
Add frame.p2p_dir, a filterable field, 0=sent, 1=recvd
Make p2p_dir available in packe_info, as I think it will be needed
in VJ COMP and UNCOMP dissection.

Guy Harris 706bd5e1fc Shomiti Surveyor 3.x appears to have changed the version number in the
file header to 4; fortunately, as they appear to put their extensions to
snoop into the padding at the end of the record, all their capture files
look alike to programs such as snoop and Ethereal that ignore the
padding, so we can just treat version 4 just like version 2 (unless and
until Brent decides a new snoop format is called for, changes the record
header, and picks a version number that's the same as one used by
Shomiti).

Gilbert Ramirez f52ffba407 Change wtap_read() API so that the data offset is set via a pointer, and
a "keep reading" boolean value is returned from the function.
This avoids having to hack around the fact that some file formats truly
do have records that start at offset 0. (i4btrace and csids have no
file header. Neither does the pppdump-style file that I'm looking at right now).

Laurent Deniel 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).

Guy Harris 4df46758e3 If we have a random stream open for a compressed Sniffer file, have the
sequential pass through the file build a list of information about the
compressed blobs, with the starting offset in the compressed file and in
the uncompressed byte stream for each blob.

When seeking on the random stream, check whether the target location is
within the uncompressed buffer we currently have; if not, use that list
to figure out which blob contains the target location, and read that
blob into the buffer.  Then, as we now know that the target location is
within the uncompressed buffer we currently have, just move the current
pointer into that buffer to the target location.

This means we don't have to read forwards through any uninteresting
blobs in order to seek forwards, and don't have to go all the way back
to the beginning and seek forwards in order to seek backwards.

Guy Harris 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.

Olivier Abad 9348644164 Support for capturing packet data from a pipe (a FIFO, or standard input).
capture.c :
- modified capture() to try to open an interface as a pipe if pcap_open_live()
  failed, and then read data in libpcap format from this pipe ;
- add new functions used by capture() : pipe_open_live() and pipe_dispatch()
  which are equivalents to the pcap_ functions.

libpcap.[ch] :
- moved the MAGIC and headers definitions from libpcap.c to libpcap.h
  because capture() now needs it.

Guy Harris ec9f9cb687 Add a script, "aclocal-flags", which figures out where
1) aclocal expects autoconf/automake macros to be hidden;

	2) GTK+ hid its autoconf/automake macros;

and, if both places exist but aren't the same directory, returns a "-I"
flag to tell aclocal to look in GTK+'s directory.

Then have "autogen.sh", and Makefiles in directories with "acinclude.m4"
files, use that script and pass what flag it supplies, if any, to
aclocal.

This should, I hope, avoid problems such as those FreeBSD systems where
GTK+ was installed from a port or package (and thus stuck its macros in
"/usr/X11R6/share/aclocal") but aclocal doesn't look there.

(It doesn't solve the problem of somebody downloading and installing,
say, libtool from source - which means it probably shows up under
"/usr/local", with its macros in "/usr/local/share/aclocal" - on a
system that comes with aclocal (meaning it probably just looks in
"/usr/share/aclocal", but that may be best fixed by, whenever you
download a source tarball for something that's part of your OS,
configuring it to install in the standard system directories and
*overwriting* your OS's version.)

Guy Harris 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.

Guy Harris 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.

Guy Harris 7843ac6d0e Add routines to Wiretap to allow a client of Wiretap to get:
a pointer to the "wtap_pkthdr" structure for an open capture
	file;

	a pointer to the "wtap_pseudo_header" union for an open capture
	file;

	a pointer to the packet buffer for an open capture file;

so that a program using "wtap_read()" in a loop can get at those items.

Keep, in a "capture_file" structure, an indicator of whether:

	no file is open;

	a file is open, and being read;

	a file is open, and is being read, but the user tried to quit
	out of reading the file (e.g., by doing "File/Quit");

	a file is open, and has been completely read.

Abort if we try to close a capture that's being read if the user hasn't
tried to quit out of the read.

Have "File/Quit" check if a file is being read; if so, just set the
state indicator to "user tried to quit out of it", so that the code
reading the file can do what's appropriate to clean up, rather than
closing the file out from under that code and causing crashes.

Have "read_cap_file()" read the capture file with a loop using
"wtap_read()", rather than by using "wtap_loop()"; have it check after
reading each packet whether the user tried to abort the read and, if so,
close the capture and return an indication that the read was aborted by
the user.  Otherwise, return an indication of whether the read
completely succeeded or failed in the middle (and, if it failed, return
the error code through a pointer).

Have "continue_tail_cap_file()" read the capture file with a loop using
"wtap_read()", rather than by using "wtap_loop()"; have it check after
reading each packet whether the user tried to abort the read and, if so,
quit the loop, and after the loop finishes (even if it read no packets),
return an indication that the read was aborted by the user if that
happened.  Otherwise, return an indication of whether the read
completely succeeded or failed in the middle (and, if it failed, return
the error code through a pointer).

Have "finish_tail_cap_file()" read the capture file with a loop using
"wtap_read()", rather than by using "wtap_loop()"; have it check after
reading each packet whether the user tried to abort the read and, if so,
quit the loop, and after the loop finishes (even if it read no packets),
close the capture and return an indication that the read was aborted by
the user if that happened.  Otherwise, return an indication of whether
the read completely succeeded or failed in the middle (and, if it
failed, return the error code through a pointer).

Have their callers check whether the read was aborted or not and, if it
was, bail out in the appropriate fashion (exit if it's reading a file
specified by "-r" on the command line; exit the main loop if it's
reading a file specified with File->Open; kill the capture child if it's
"continue_tail_cap_file()"; exit the main loop if it's
"finish_tail_cap_file()".

Guy Harris 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).
