Add the option to enter a filter with an absolute time
value in UTC. Otherwise the value is interpreted in
local time.
The syntax used is an "UTC" suffix, for example:
frame.time == "Dec 31, 2002 13:55:31.3 UTC"
This also changes the behavior of "Apply Selected as filter".
Fields using a local time display type will use local time
and fields using UTC display type will be applied using UTC.
Fixes#13268.
This makes it easier to understand the code, avoids conflicts
and ugly and unnecessary casts.
The field display enum has evolved over time from integer types
to a type generic parameter.
Mostly straightforward. The only complication was
proto_tree_add_split_bits_crumb which needed some manipulation to
guarantee a non-null tree so we could use its memory scope.
This is one of the last non-dissector uses of wmem_packet_scope!
There are a bunch of near-identical macros here, but I'm gonna change
one at a time or else the builder times out at the number of files
changed in one merge.
Implement little endian support for tvb_get_bits family of functions.
The big/little endian refers to bit numbering within an octet. In big
endian, the most significant bit is considered bit 0, while in little
endian the least significant bit is considered bit 0.
Add encoding parameters to proto tree bits format family functions.
Specify ENC_BIG_ENDIAN in all dissectors using these functions except in
USB HID that requires ENC_LITTLE_ENDIAN to work correctly.
When formatting bits values, always display most significant bit on the
leftmost position regardless of the encoding. This results in no gaps
between octets and makes the displayed value comprehensible.
Close#4478Fix#17014
This utility function is useful outside of epan. Move it to wsutil
and export the interface.
The move isn't completely clean as it requires duplicating two small
inline functions but that was necessary to avoiding moving too much at
once.
This header was installed incorrectly to epan/wmem_scopes.h.
Instead of creating additional installation rules for a single
header in a subfolder (kept for backward compatibility) just
rename the standard "epan/wmem/wmem.h" include to
"epan/wmem_scopes.h" and fix the documentation.
Now the header is installed *correctly* to epan/wmem_scopes.h.
Make display_signed_time() take a 64-bit signed number of seconds, and,

Add an FT_CHAR type, which is like FT_UINT8 except that the value is
displayed as a C-style character constant.
Allow use of C-style character constants in filter expressions; they can
be used in comparisons with all integral types, and in "contains"
operators.
Use that type for some fields that appear (based on the way they're
displayed, or on the use of C-style character constants in their
value_string tables) to be 1-byte characters rather than 8-bit numbers.

Create a "registration" system for Follow functionality so most of the work can be abstracted into a dissector and GUI can just be responsible for "display".
This also removes the global variables in follow.c to open up multithreading possibilities.
TCP, UDP and HTTP all have the same "tap interface" for Follow functionality (passing a tvb with byte data to "follow"). SSL still has it's own behavior, so Follow structures have to take that into account.
TShark through the Follow registration now has support for HTTP.
The only thing possibly missing is dynamic menu generation to further reduce explicit knowledge of Follow "type" (and rely on registration)

Assuming *any* of the routines that generate printable strings should be
thought of as "for internal use by libwireshark routines only, not by
dissectors", the ones that *are* used by dissectors obviously shouldn't
be. The ability for dissectors to register address types certainly
expands the list of routines they would use.
Move everything used by dissectors from to_str-int.h into to_str.h, and
have dissectors not include to_str-int.h.
