Guy Harris 500eb99cd9 Add a third date format, ABSOLUTE_TIME_DOY_UTC, to show UTC with the
date as YYYY/DDD, where DDD is a 1-origin day of year.  Move the formats
to a "time_fmt.h" file, included by the headers that use it.  Have
abs_time_to_str() and abs_time_secs_to_str() take the date format value,
rather than a Boolean "show this as UTC" flag, as an argument.  Document
the ABSOLUTE_TIME_ formats a bit better.  Use that format in the CCSDS
and VCDU dissectors, rather than having those dissectors do the
formatting themselves.

Guy Harris 8e236e55de For fields of type FT_ABSOLUTE_TIME, have the "display" value be one of
ABSOLUTE_TIME_LOCAL or ABSOLUTE_TIME_UTC, indicating whether to display
the date/time in local time or UTC. (int)ABSOLUTE_TIME_LOCAL ==
(int)BASE_NONE, so there's no source or binary compatiblity issue,
although we might want to eliminate BASE_NONE at some point and have the
BASE_ values used with integral types start at 0, so that you can't
specify BASE_NONE for an integral field.

Guy Harris a4b7135ce3 Rename BASE_STRUCTURE_RESET to BASE_DISPLAY_E_MASK, to clarify that it's
a mask to select the base_display_e value from a display field in a
header_field_info structure.

Never select that value by masking out the BASE_RANGE_STRING flag bit,
as that won't continue to work if more flag bits, or other bitfields,
are added.  Instead, mask with BASE_DISPLAY_E_MASK.

Note that the base_display_e value and BASE_RANGE_STRING flag are only
for integral field types, and clarify what BASE_DISPLAY_E_MASK is.

Give at least one of the reasons why hiding protocol fields is not
considered a good idea.

Kovarththanan Rajaratnam 9c512f7cb4 Introduce TRY_TO_FAKE_THIS_REPR which is an optimization similar to the existing TRY_TO_FAKE_THIS_ITEM.

Jaap Keuter 0fde67dd54 From Andrew Narver:
Currently, if you call proto_tree_free on anything other than the root node of a tree 
the tree will get left in an inconsistent state.  This is because the parent is left pointing 
to the newly freed child.

The traversal code is updated, the parent node update is currently disabled since 
freeing is done for the complete tree only at this time, so there is no need to keep 
the parent node consistent.

Anders Broman da85c3dfab From Alexey Neyman :
This patch implements a function for dissecting bitfields with better control
over the resulting representation than the existing proto_tree_add_bitmask()
routine. This function will be used by reworked IPMI/ATCA dissector (bug 2048).

The function is described in README.developer. In short, the differences are as
follows:

- The new function does not require a hf_XXX field for the whole bitmask. When
the bitmask includes several unrelated fields, such hf_XXX field does not make
sense.

- The new function allows better control over the way the sub-item descriptions
are added to the top-level item. For example, proto_tree_add_bitmask() function
does not add non-enumerated integers, does not use true_false_string to display
boolean.

- The new function allows to specify "fallback" text for the top-level item
which is used if no items were added to the top-level item.

Stig Bjørlykke a2d1e9005d This patch adds support for configuration profiles, which can be used to
configure and use more than one set of preferences and configuration files.

This can be found in the "Configuration Profiles..." menu item from the Edit
menu, or by pressing Shift-Ctrl-A.  It's also possible to start wireshark
and tshark with a named profile by using the "-C ProfileName" option.
A new status pane in the main window will show the current profile.

The configuration files currently stored in the Profiles are:
- Preferences
- Capture Filters
- Display Filters
- Coloring Rules
- Disabled Protocols
- User Accessible Tables

The recent data are by design not added to the profile.

Planned future enhancements:
- make a more convenient function to switch between profiles
- add a "clone profile" button to copy an existing profile
- make the profiles list active and accept return as OK
- save users "Decode as" in the profile
- make new, clone and deletion of profiles more secure
- make some of the recent values available in the profile

This patch also fixes:
- setting default status pane sizes
- a bug setting status pane for packets when not having main lower pane.

Guy Harris 44c0624bd9 Add a WIRESHARK_RUN_FROM_BUILD_DIRECTORY environment variable on UN*X;
if set, and if the program isn't running with additional privileges,
it'll treat the directory in which the program is found as the data
directory.

If, on Windows, the version-number subdirectory of {data
directory}\plugins doesn't exist (which is assumed to mean that the
program is being run from the build directory), or if, on UN*X,
WIRESHARK_RUN_FROM_BUILD_DIRECTORY is set, the plugin directory is the
"plugins" subdirectory of the data directory, and all subdirectories of
that directory are scanned for plugins, as the "plugins" subdirectory of
the build directory contains subdirectories for the plugins; this means
that if we're running from the build directory, we'll find the plugins
we built in the build tree.

When generating the wireshark-filter man page, run tshark with
WIRESHARK_RUN_FROM_BUILD_DIRECTORY set, so it uses the plugins from the
build to generate the list of filters.

have it return a Boolean indication of whether the string could be

null, have it just return the Boolean and not construct the string.

Get rid of proto_can_match_selected() -
proto_construct_match_selected_string() can be used for that, which
means we have only one piece of code that knows whether a "match
selected" string can be constructed or not.

Have proto_construct_match_selected_string() support matching
zero-length FT_NONE (and FT_PCRE, but that shouldn't happen) fields even
if there's no epan_dissect_t, as such a match just checks whether the

Anders Broman 61b223303a From Greg Morris:
Modification to (proto.h) is made to add an additional expert group type of PI_REQUEST_CODE to allow Request tag information to be passed to the expert tap. This is for such reasons where a dissector would like to echo specific information about certain types of requests. For example: NCP connection request is really a request not a REPLY_CODE. Same is true for the TCP SYN request.

Changes to packet-ncp.c
1. Server broadcast message flag. Now indicates if the message is a pending message or an oplock clear notification.
2. Cleanup of packet signature detection process. Previous method had some flaws so I redesigned it. Appears to be solid now.
3. Echo NCP Server Session information to expert tap.
 
Note on item #3: NCP Connection+Task = NCP Session, a Single connection can have many tasks. The server sees each connection/task as a unique session. For this reason the NCP session information is now echoed to the expert composite statistics so that you can easily identify the different NCP processes and sessions. It is important to NCP analysis to understand that each session is most likely a different program on the requesting host sharing the same NCP connection.
 
Changes to packet-ncp2222.inc
1. Comment out the echo of NCP connection info to expert tap. Replaced by NCP sessions.
2. Add displayEID in request decode (resolves Coverity defect for dead code in NCP dissector)
 
Changes to ncp2222.py
1. Fix for endian display of bindery object type in NCP 0x1720.
2. Fix for size of bindery object type to 2 bytes instead of 4 to match other bindery NCP's.

Ronnie Sahlberg fa1ee7667b performance enhancement to proto.c
Removed the GMemChunk used to allocate/free field_info structures
and used a free list to store the freed structs until they are allocated again.

Ethereal will allocate more field_info structs as it needs to but never free them. Instead the are just placed in a cheap and fast free list so that if we
want to use the struct again, this will be fast.

This affects the speed of the two functions
alloc_field_info() that should be slightly faster now
free_field_info() that was replaced with a 2 line macro.

All in all  my testing suggests that ethereal is 2-3% faster with this patch.

the function should now be virtually zero cost

Guy Harris ca318813a4 Rename "proto_alloc_dfilter_string()" to
"proto_construct_dfilter_string()", to more accurately reflect what it
does.

Give it, and "proto_can_match_selected()", an "epan_dissect_t *"
argument, which replaces the raw data pointer argument to
"proto_construct_dfilter_string()".

For fields that don't have a type we can directly filter on, we don't
support filtering on the field as raw data if:

	the "epan_dissect_t *" argument is null;

	the data source tvbuff for the field isn't the tvbuff for the
	"epan_dissect_t" in question (i.e., it's in the result of a
	reassembly, and "frame[N:M]" can't get at it).

Trim the length the raw data in the case of such a field to the length
of the tvbuff for the "epan_dissect_t" in question, so we don't go past
it.  Fetch the raw data bytes to match from that tvbuff.

Have "proto_construct_dfilter_string()" return a null pointer if it
can't construct the filter string, and have "protocolinfo_packet()" in
the tap-protocolinfo tap ignore a field if
"proto_construct_dfilter_string()" can't construct a filter string for
it - and have it pass NULL as the "epan_dissect_t *", for now.  If
somebody decides it makes sense to dump out a "frame[N:M] =" value for
non-registered fields, it can be changed to pass "edt".

Jörg Mayer 48be4e530d Removed trailing whitespaces from .h and .c files using the
winapi_cleanup tool written by Patrik Stridvall for the wine
project.

Guy Harris 6e56c25c9d From Ulf Lamping: add a new FT_FLOAT type, for single-precision
floating-point numbers, and display all the significant digits for both
single-precision and double-precision floating-point numbers in the
protocol tree, not just what "%g" does (6 digits).

Put in comments explaining how the length of filter strings is computed,
and fix some of the computations.

Jörg Mayer 3105ee542f Replace the types from sys/types.h and netinet/in.h by their glib.h
equivalents for the epan/ directory but leave winsock2.h in inet_pton.c
and inet_ntop.c for now (can't estimate the consequences).

Guy Harris 73ef5a2753 WinPcap 2.3's <pcap.h> includes <packet32.h>, and WinPcap 2.3's
<packet32.h> includes <winsock2.h>; we include that rather than
<winsock.h>, to avoid errors due to conflicting declarations in
<winsock.h> and <winsock2.h>.

Guy Harris e390d7e0cc Make the "-G" flag take an argument. If no arugment is specified, or if
the argument is "fields", dump out a table of the fields, as we
currently do; if the argument is "protocols", dump out a table of the
protocols.

Guy Harris 30f02bc99c Move the code to build the balanced tree of fields into "proto_init()",
move the code from "dfilter_lookup_token()" into
"proto_registrar_get_byname()", and get rid of "dfilter_lookup_token()"
and have its callers call "proto_registrar_get_byname()" instead.

Guy Harris 50155a975d From Phil Williams: support for looking up fields by name.
Clean up some white space, and one non-extern declaration in
"epan/proto.h".

Guy Harris 5de2533f2d Start assigning ett_ values at 0, rather than 1; get rid of the reserved
ETT_NONE entry.

Initialize the "tree_type" field of a "field_info" structure to -1,
meaning "this has not been given a subtree".  Add checks before using
that field that it's in range.  That way, you have to create a subtree
before putting protocol tree items under another item.

We allocate the "tree_is_expanded" array when we've registered all
dissectors; there's no need to allocate it while we're registering
dissectors and, in fact, doing so means we leak memory (the memory for
the version we allocated while registering dissectors).

Guy Harris 6a21dc7e44 Don't give tvbuffs names; instead, give data sources names, where a
"data source" has a name and a top-level tvbuff, and frames can have a
list of data sources associated with them.

Use the tvbuff pointer to determine which data source is the data source
for a given field; this means we don't have to worry about multiple data
sources with the same name - the only thing the name does is label the
notebook tab for the display of the data source, and label the hex dump
of the data source in print/Tethereal output.

Clean up a bunch of things discovered in the process of doing the above.

Guy Harris e0828c513d The typedef in "epan/value_string.h" declares "value_string" to be a
typedef for "struct _value_string"; as such, the incomplete structure
declaration in "epan/proto.h" should declare "struct _value_string", not
"struct value_string", and casts and declarations in that header should
also use "struct _value_string", not "struct value_string".

its declaration.

Gilbert Ramirez 791f5774d0 Provide for per-protocol-tree data in the proto_tree code.
Put a hash-table of "interesting" fields in the per-proto-tree data.
The dfilter code records which fields/protocols are "interesting" (by which
I mean, their value or existence is checked). Thus, the proto_tree routines
can create special arrays of field_info*'s that are ready for the dfilter
engine to use during a filter operation.

Also store the "proto_tree_is_visible" boolean, renamed "visible", in
the per-proto-tree data.

Move epan_dissect_t to its own header file to make #include dependencies
easier to handle.

Provide epan_dissect_fill_in_columns(), which accepts just the epan_dissect_t*
as an argument.

epan_dissect_new() needs to be followed by epan_dissect_run() for the
dissection to actually take place. Between those two calls,
epan_dissect_prime_dfilter() can be run 0, 1, or multiple times in order to
prime the empty proto_tree with the "intersesting" fields from the dfilter_t.

Gilbert Ramirez f1b64de80e Dfilter code finds field under *any* parent's subtree, not just
the parent under which the field was registered.

This is the *unoptimized* version, to give developers something
to use while the optimized version is being created.
