Commitaf0691342b
and commit80ae370811
both added proto_disable_all. Take the one from the80ae370811
, which made changes to allow protocols to be enabled by proto_enable_proto_by_name() even if they are not disabled by default, which allows --only-protocols to work without changing the disabled-by-default setting of a protocol. We don't want to change the disabled by default setting, because that causes the disabled status to be persistent even when changing Configuration Profiles with the GUI, instead of being reset. In general, command line options that temporarily override the Configuration Profile at startup are cleared when switching to a new profile via the profile, and we don't want to make an exception.

The protocol tree related functions.<BR>
|
|
A protocol tree will hold all necessary data to display the whole dissected packet.
|
|
Creating a protocol tree is done in a two stage process:
|
|
A static part at program startup, and a dynamic part when the dissection with the real packet data is done.<BR>
|
|
The "static" information is provided by creating a hf_register_info hf[] array, and register it using the
|
|
proto_register_field_array() function. This is usually done at dissector registering.<BR>
|
|
The "dynamic" information is added to the protocol tree by calling one of the proto_tree_add_...() functions,
|
|
e.g. proto_tree_add_bytes().

|
|
* complement and 1's complement (and nobody's put any IBM 709x's on
|
|

|
|
*
|
|
* However:
|
|
*
|
|
* for floating-point numbers, in addition to IEEE decimal
|
|
* floating-point, there's also IBM System/3x0 and PDP-11/VAX
|
|
* floating-point - most protocols use IEEE binary, but DCE RPC
|
|
* can use other formats if that's what the sending host uses;
|
|
*
|
|
* for character strings, there are various character encodings
|
|
* (various ISO 646 sets, ISO 8859/x, various other national
|
|
* standards, various DOS and Windows encodings, various Mac
|
|
* encodings, UTF-8, UTF-16, other extensions to ASCII, EBCDIC,
|
|
* etc.);
|
|
*
|
|
* for absolute times, there's UNIX time_t, UNIX time_t followed
|
|
* by 32-bit microseconds, UNIX time_t followed by 32-bit
|
|
* nanoseconds, DOS date/time, Windows FILETIME, NTP time, etc..

*
|

* We might also, in the future, want to allow a field specifier to

* indicate the encoding of the field, or at least its default
|

* encoding, as most fields in most protocols always use the

* same encoding (although that's not true of all fields, so we

|

*
|

|

* proto_tree_add_item(), and possibly to specify in a field

|
* definition (e.g., ORed in with the type value).
|
|
*
|
|
* Currently, proto_tree_add_item() treats its last argument as a
|
|
* Boolean - if it's zero, the field is big-endian, and if it's non-zero,
|
|
* the field is little-endian - and other code in epan/proto.c does
|
|
* the same. We therefore define ENC_BIG_ENDIAN as 0x00000000 and

* ENC_LITTLE_ENDIAN as 0x80000000 - we're using the high-order bit
|

* encoding in the lower bits.

|
|
* second since the NTP epoch, with the upper 32 bits first and the

|
* lower 32 bits second, even when little-endian.)

|
* ENC_TIME_TOD - 8 bytes, as a count of microseconds since the System/3x0
|
|
* and z/Architecture epoch (1900-01-01 00:00:00 GMT).
|
|
*
|
|
* ENC_TIME_RTPS - 8 bytes; the first 4 bytes are seconds since the UN*X

* If the time is absolute, it's milliseconds since the UN*X epoch.
|
|
*
|
|
* ENC_TIME_USECS - 8 bytes, representing a value in microseconds.

|
|
* ENC_TIME_NSECS - 8 bytes, representing a value in nanoseconds.

|
|
* ENC_TIME_SECS_NTP - 4 bytes, representing a count of seconds since

* the NTP epoch.
|
|
*
|
|
* ENC_TIME_RFC_3971 - 8 bytes, representing a count of 1/64ths of a

|
|
* in RFC 3971.
|
|
*
|
|
* ENC_TIME_MSEC_NTP - 4-8 bytes, representing a count of milliseconds since

Supported: FT_BYTES, FT_UINT_BYTES, FT_OID, FT_REL_OID, and FT_SYSTEM_ID.

The item is extracted from the tvbuff handed to it, based on the ENC_* passed

in for the encoding, and the retrieved byte array is also set to *retval so the

caller gets it back for other uses.
|

This function retrieves the value even if the passed-in tree param is NULL,

so that it can be used by dissectors at all times to both get the value
|

and set the tree item to it.
|
|
|
|
Like other proto_tree_add functions, if there is a tree and the value cannot
|
|
be decoded from the tvbuff, then an expert info error is reported. For string
|
|
encoding, this means that a failure to decode the hex value from the string
|
|
results in an expert info error being added to the tree.
|

If encoding is string-based, it will convert using tvb_get_string_bytes(); see

|
|
|
This function is used to add a custom string *value* to the protocol tree.
|
|
Do not format the string value for display, for example by using format_text().
|
|
The input string represents packet data, not a display label. Formatting
|
|
labels is a concern of the UI. Doing that here would change the meaning of the packet
|
|
data, restrict the options for formatting later and make display filtering unintuitive
|
|
for whitespace and other special characters.
