Guy Harris 98473c77b6 Ethereal now requires 64-bit integer support, so get rid of the tests of
G_HAVE_GINT64.

Get rid of the floating-point stuff in the Etherpeek Classic file
reading code, just use 64-bit integers.  Fix up the calculation of the
nanoseconds portion of the time stamp.

Ulf Lamping 6f43fbb2f0 EVERYTHING IN THE BUILDBOT IS GOING TO BE RED!!! Sorry!
I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ...

What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere.

As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon.

Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way...

As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number...

Guy Harris 8a8b883450 Set the svn:eol-style property on all text files to "native", so that
they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

Guy Harris ba72e955dc Have "wtap_read()" set "wth->phdr.pkt_encap" to "wth->file_encap",
rather than requiring individual capture file type handlers to do it
(unless they're doing per-packet encapsulation, in which case we check
to make sure they didn't *leave* it as WTAP_ENCAP_PER_PACKET).

Guy Harris 2cbe1a0bf5 Fix up a comment to note that this is also used for AiroPeek, and used
only for versions 5, 6, and 7 of the file format.

Add another comment explaining why this refers to "etherpeek" even
though it's also used for AiroPeek and probably also TokenPeek.

Guy Harris 2528c053ce Supply a pseudo-header for all 802.11 packets; add an "fcs_len" field to
it, similar to the Ethernet pseudo-header's "fcs_len" field, and use it
in the 802.11 dissector.

Guy Harris d6cd61061e Have the Wiretap open, read, and seek-and-read routines return, in
addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors.  Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.

Add messages for cases where those errors were returned without printing
an additional message.

Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.

Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument.  (That handles a lot of the work of putting the info
string into the error message.)

Make some variables in "ascend-grammar.y" static.

Check the return value of "erf_read_header()" in "erf_seek_read()".

Get rid of an unused #define in "i4btrace.c".

Guy Harris a98aa75a58 WildPackets' EtherHelp appears to write EtherPeek-compatible files,
except that the 0x80 bit is turned on in the file version number field.
Turn that bit off before processing that field.

Guy Harris be2736adcf Have a pseudo-header for Ethernet packets, giving the size of the FCS -
0 means "there is no FCS in the packet data", 4 means "there is an FCS
in the packet data", -1 means "I don't know whether there's an FCS in
the packet data, guess based on the packet size".

Assume that Ethernet encapsulated inside other protocols has no FCS, by
having the "eth" dissector assume that (and not check for an Ethernet
pseudo-header).

Have "ethertype()" take an argument giving the FCS size; pass 0 when
appropriate.

Fix up Wiretap routines to set the pseudo-header.  This means we no
longer use the "generic" seek-and-read routine, so get rid of it.

Guy Harris 9fa514388c GCC 3.3 noticed that checking whether the length of the slice is > 65535
is pointless, as it's a 16-bit unsigned quantity.  Remove those checks -
but note in a comment that WTAP_MAX_PACKET_SIZE must be at least 65535
(as there might well be link-layer types with packets at least that
large).

Guy Harris 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.

Guy Harris 8b9f8e4f3b The length passed into "seek_read" routines is the length supplied by
the "read" routine, which means it's already had any end-of-frame
padding/FCS removed; we don't need to remove it in the "seek_read"
routine.

Guy Harris cbf5c537c4 From Joerg Mayer: remove unused variables and declarations of
non-existent functions.

Remove the "filetype" argument from the "can_write_encap" functions for
particular capture file types - the argument value is implicit, in that
the routine being called is the routine for that particular file type.

Guy Harris 89a4acb438 Have Wiretap set the snapshot length to 0 if it can't be derived from
reading the capture file.  Have callers of "wtap_snapshot_length()"
treat a value of 0 as "unknown", and default to WTAP_MAX_PACKET_SIZE (so
that, when writing a capture file in a format that *does* store the
snapshot length, we can at least put *something* in the file).

If we don't know the snapshot length of the current capture file, don't
display a value in the summary window.

Don't use "cfile.snap" as the snapshot length option when capturing -
doing so causes Ethereal to default, when capturing, to the snapshot
length of the last capture file that you read in, rather than to the
snapshot length of the last capture you did (or the initial default of
"no snapshot length").

Redo the "Capture Options" dialog box to group options into sections
with frames around them, and add units to the snapshot length, maximum
file size, and capture duration options, as per a suggestion by Ulf
Lamping.  Also add units to the capture count option.

Make the snapshot length, capture count, maximum file size, and capture
duration options into a combination of a check box and a spin button.
If the check box is not checked, the limit in question is inactive
(snapshot length of 65535, no max packet count, no max file size, no max
capture duration); if it's checked, the spinbox specifies the limit.
Default all of the check boxes to "not checked" and all of the spin
boxes to small values.

Use "gtk_toggle_button_get_active()" rather than directly fetching the
state of a check box.

Guy Harris 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.

Guy Harris 6cdc5dfde2 In the EtherPeek file reader, keep the capture start time in a private
data structure attached to the "wtap" structure, rather than in a
pseudo-header structure; get rid of the EtherPeek pseudo-header
structure, as it's not actually used as a pseudo-header, it's just used
as private data for the EtherPeek reader.

Get rid of an extra level of indentation in switch statements.

Guy Harris faacd2b71c The data structure for per-packet headers for Mac V5 and V6 Etherpeek
files would put a 32-bit quantity on a 16-bit boundary without padding;
this means that many compilers will insert the padding and thus make the
structure not match what's in the file.

Instead of using a C structure, #define values for the offsets of
fields, read the header into an array of bytes, and extract values using
the offsets.

Guy Harris 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.
