2021-09-01tvbuff: convert helper methods to pinfo->poolEvan Huus1-2/+2
A few of them just needed scratch memory, so allocate and free it manually after doing any exception-raising checks. A few others were returning memory, and needed conversion to accept a wmem scope argument.

2021-04-30Cast away the return value of g_strlcpy() and g_strlcat().Guy Harris1-2/+2
Most of the time, the return value tells us nothing useful, as we've already decided that we're perfectly willing to live with string truncation. Hopefully this keeps Coverity from whining that those routines could return an error code (NARRATOR: They don't) and thus that we're ignoring the possibility of failure (as indicated, we've already decided that we can live with string truncation, so truncation is *NOT* a failure).

2020-06-19Fix the type of arrays of pointers to hf_ values for bitfield routines.Guy Harris1-3/+3
The static arrays are supposed to be arrays of const pointers to int, not arrays of non-const pointers to const int. Fixing that means some bugs (scribbling on what's *supposed* to be a const array) will be caught (see packet-ieee80211-radiotap.c for examples, the first of which inspired this change and the second of which was discovered while testing compiles with this change), and removes the need for some annoying casts. Also make some of those arrays static while we're at it. Update documentation and dissector-generator tools.

2018-12-27Try to squeeze some bytes out of the frame_data structure.Guy Harris1-3/+3
Make the time stamp precision a 4-bit bitfield, so, when combined with the other bitfields, we have 32 bits. That means we put the flags at the same structure level as the time stamp precision, so they can be combined; that gets rid of an extra "flags." for references to the flags. Put the two pointers next to each other, and after a multiple of 8 bytes worth of other fields, so that there's no padding before or between them. It's still not down to 64 bytes, which is the next lower power of 2, so there's more work to do.

They already know who they are when they register themselves. Saving the handle then to avoid finding it later. Not sure if this will increase unnecessary register_dissector functions (instead of using create_dissector_handle in proto_reg_handoff function) when other dissectors copy/paste, but it should make startup time a few microseconds better.

2016-08-31Don't do any Decode As stuff for dissector tables not used with Decode As.Guy Harris1-1/+1
Have all dissector tables have a "supports Decode As" flag, which defaults to FALSE, and which is set to TRUE if a register_decode_as() refers to it. When adding a dissector to a dissector table with a given key, only add it for Decode As if the dissector table supports it. For non-FT_STRING dissector tables, always check for multiple entries for the same protocol with different dissectors, and report an error if we found them. This means there's no need for the creator of a dissector table to specify whether duplicates of that sort should be allowed - we always do the check when registering something for "Decode As" (in a non-FT_STRING dissector table), and just don't bother registering anything for "Decode As" if the dissector table doesn't support "Decode As", so there's no check done for those dissector tables.

It ends up dragging in libwireshark headers, which programs not linking with libwireshark shouldn't do. In particular, including <epan/address.h> causes some functions that refer to libwireshark functions to be defined if the compiler doesn't handle "static inline" the way GCC does, and you end up requiring libwireshark even though you shouldn't require it. Move plurality() to wsutil/str_util.h, so that non-libwireshark code can get it without include epan/packet.h. Fix includes as necessary.
