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!

2021-09-26USB HID: Parse bit fields with correct bit orderTomasz Moń1-1/+1
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 #4478 Fix #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.
2021-07-26Move epan/wmem/wmem_scopes.h to epan/João Valverde1-1/+1
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.

2016-01-12Refactor "Follow Stream" functionality on all GUI interfaces.Michael Mann1-1/+1
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) Bug: 11988 Change-Id: I559d9ee1312406ad0986d4dce9fa67ea2103b339 Reviewed-on: https://code.wireshark.org/review/13161 Reviewed-by: Michael Mann <mmann78@netscape.net>

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. (Perhaps we should just get rid of to_str-int.h altogether.)

It replaces both the internal solve_address_to_name() routine and get_addr_name(), and can, for example, handle the special WLAN address types rather than leaving them unresolved even with an ethers file.
