and clearing packets, Qualifier bit in data packets.

with not terminating their arrays because they knew the limits of the
value used to look up strings in the value_string array, but the
dfilter_expr_dlg does not know these limits and must rely on the terminating
{0, NULL} record.
Also, in SNA fixed a bug in which a field should have been defined as FT_UINT8
but was defined as FT_BOOLEAN.
In WTP, fixed a value string which had duplicate keys.

"prefs_register_module()" except that it takes a protocol index as
returned by "proto_register_protocol()" as its first argument, rather
than taking two character strings as arguments as its first two
arguments, and uses the protocol's abbreviation as the name to use for
preferences in the preferences file and the "-o" flag and uses the
protocol's short name as the name to use in the tabs in the
"Edit->Preferences" window.

protocols, in addition to adding structures to the list of filterable
fields. Give it an extra argument that specifies a "short name" for the
protocol, for use in such places as
pinfo->current_proto;
the dialog box for constructing filters;
the preferences tab for the protocol;
and so on (although we're not yet using it in all those places).
Make the preference name that appears in the preferences file and the
command line for the DIAMETER protocol "diameter", not "Diameter"; the
convention is that the name in question be all-lower-case.
Make some routines and variables that aren't exported static.
Update a comment in the ICP dissector to make it clear that the
dissector won't see fragments other than the first fragment of a
fragmented datagram.

the value entry on the type of the field, not on whether the value entry
is visible; the value entry is hidden, in "field_select_row_cb()", after
"build_boolean_values()" is called, and building the list in
"build_boolean_values()" will cause an entry in that list to be
selected, and "value_list_sel_cb()" will be called as a result, so it
can't correctly base its decision on whether to set the value entry on
whether the entry is visible, as it's not yet been made invisible.
Fix a comment.

display tree, based on Jeff Foster's dialog box for selecting fields.
Make the dialog box for browsing filters into a dialog box for
constructing filters; make the "Apply" button and the "OK" button apply
the filter in the text entry box in the dialog, not the currently
selected filter (selecting a filter puts it in that text entry box, but
the user may edit it afterwards, or may use the aforementioned dialog
box to construct a filter not in the list).
Get rid of extra declarations of "m_r_font" and "m_b_font" in
"proto_draw.c"; they're declared in "gtk/gtkglobals.h", which it includes.

or "[Malformed Frame]" to the Info column.
Make some dissectors set the Protocol column and clear the Info column
before fetching anything from the tvbuff they were handed, so that if
the frame is short or malformed, it'll be marked as being the right
top-level protocol, and the Info column won't have cruft left over from
the previous protocol.

called by "dissect_lapbether()". "packet-lapbether.c" included
"packet-lapb.h", to get "dissect_lapb()" declared, but that header file
doesn't exist.
Dissectors should call other dissectors indirectly, so have the LAPB
dissector register itself and have the LAPB-over-Ethernet dissector get
that handle and call the LAPB dissector through that handle, rather than
making the LAPB dissector non-static and adding a "packet-lapb.h" header
to declare it.
Remove some unnecessary includes from "packet-lapbether.c".

the parent tvbuff, we have to set "pinfo->len" and "pinfo->captured_len"
unless we know for certain that *no* old-style dissectors will be called
later, because old-style dissectors get their length information from
"pi.len" and "pi.captured_len".

Add a new subdissector table in the LLC dissector for protocol IDs with
a Cisco OUI, and register the CDP, CGMP, and VTMP dissectors in that
table, rather than calling them via a switch statement.
Register the ISL dissector by name, and have the Ethernet dissector call
it via a handle.
Fix the handling of the checksum field in the CDP dissector.
The strings in CDP are counted, not null-terminated; treat them as such.
Fix the handling of the encapsulated frame CRC, and the encapsulated
frame, in the ISL dissector, at least for Ethernet frames; it may not be
correct for encapsulated Token Ring frames.

doesn't work like the read timeout in BPF - the timer doesn't start
until at least one packet has arrived.
I think that's the way read timeouts should work on *all* packet capture
mechanisms, but it does mean that Solaris will, on a quiet net, exhibit
the same symptoms that Linux used to exhibit before we put in a
"select()" call to wait until either packets arrive or a timer expires -
the "pcap_dispatch()" call blocks until a packet arrives, so the display
doesn't get updated and Ethereal doesn't respond to user input until a
packet arrives.
Furthermore, Linux isn't the only OS that lacks any read timeout
on its packet capture mechanism; the others will also have that problem.
We therefore do the "select()" on *all* platforms other than the BSDs
(where the timer starts when the read is done, and can be used for
polling); I don't know whether it's necessary on Digital UNIX, but I
suspect it's necessary on SunOS 4.x (as the 5.x "bufmod" is probably
derived from the 4.x one, and the 5.x one, as per the above, starts the
timer when a packet arrives), and it may even be necessary on 3.x, those
(BSD, SunOS including 5.x, and Digital UNIX) apparently being the only
UNIXes that appear to have such a read timeout.

on it, such as the exit status if it exited "normally" but unexpectedly.
On UNIX systems, #define the various POSIX <sys/wait.h> macros (and the
non-POSIX WCOREDUMP()" macro) if they're not defined by <sys/wait.h> (or
if we don't have <sys/wait.h>), and use them to dissect the exit status.

Change them to use facilities in Ethereal that were probably not present
when they were originally written, e.g. routines to fetch 24-bit
integers and to dump a bunch of raw bytes in hex.
Redo them to extract data from the packet as they dissect it, rather
than extracting an entire data structure at once; that way, it may be
able to dissect a structure not all of which is in the packet.
Dissect a bit more of the type-of-service metrics etc. in OSPF packets.
Make "tvb_length_remaining()" return a "gint", not a "guint"; it returns
-1 if the offset is past the end of the tvbuff.
Add a "tvb_reported_length_remaining()" routine, similar to
"tvb_length_remaining()". Use it instead of just subtracting an offset
from "tvb_reported_length()".
svn path=/trunk/; revision=2787
"tvb_length_remaining()" will return -1 if the offset argument is past
the end of the tvbuff; check for values > 0, not values != 0, when
checking to see if there's extra garbage at the end of the packet.

NUL-terminated string, starting at a given offset. The size includes
the terminating NUL. If it doesn't find the terminating NUL, it throws
the appropriate exception, as either there's no terminating NUL in the
packet or there is but it's past the end of the captured data in the
packet.
Use that routine in the TFTP dissector. As it throws an exception if
the string isn't NUL-terminated, we can just use "%s" to print option
strings; we don't need to use "%.*s" with a string length.
