2020-06-19Fix the type of arrays of pointers to hf_ values for bitfield routines.Guy Harris1-1/+1
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.

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.

The target here is the Decode As dialog where protocols have multiple registrations into a dissector table and that shows up as multiple entries in the Decode As dialog list with the same name so users are unsure which "dissector" they are choosing.

2015-11-04Don't include "file.h" if you don't need it.Guy Harris1-0/+1
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.

2014-08-09Clean up Internet checksum handling.Guy Harris1-2/+1
Add macros to set entries of a vec_t, one for use when you have a pointer to private data, and one for use when you have data in a tvbuff. The latter wraps the use of tvb_get_ptr(), so that you're not directly calling it in a dissector. Move ip_checksum() to epan/in_cksum.c, and add an ip_checksum_tvb() that wraps the use of tvb_get_ptr(). In the CARP dissector, give the length variable an unsigned type - there's no benefit to it being signed, and that requires some casts to be thrown around. In the DCCP dissector, check only against the coverage length to see if we have enough data, combine the "should we check the checksum?" check with the "*can* we check the checksum?" check in a single if, and throw a dissector assertion if the source network address type isn't IPv4 or IPv6. Get rid of inclues of <epan/in_cksum.h> in dissectors that don't use any of the Internet checksum routines. In the HIP dissector, make sure we have the data to calculate the checksum before doing so.
