2015-12-17Create capture dissector "info" structure (capture_packet_info_t)Michael Mann1-1/+1
While it currently only contains packet_counts, it will hopefully stabilize the capture function signature if more fields are added.

2015-12-14Create capture dissector tables.Michael Mann1-1/+1
They are modeled after dissection dissector tables, but for the moment, don't have/need the flexibility. They are intended to be much simpler/faster than full dissection. The two most used/needed are "wtap_encap" and "ethertype", so they were the basis of starting to use and test capture dissector table API. Others may be added in the future. The "capture dissector" function signature needed a bit of tweeking to handling "claiming" of a packet. The current application of this is capture functions returning TRUE if they affected a "type" of packet count. Returning FALSE ends up considering the packet an "other" type.

2015-09-18Make IPv4/IPv6 DiffServ fields uniformJoão Valverde1-2/+13
Replace DSCP/ECT/CE with DSCP/ECN for IPv6. Introduce short descriptions for DSCP/ECN values. Formating changes: - Make IPv4 and IPv6 as similar as possible. - Display short abbreviations only for "Differentiated Services Field". - Display DiffServ field as hex for IPv4. - Elide leading zeros from hex representation from DiffServ field for IPv6. - Display DSCP/ECN as decimal in subtree (same as "IP DSCP" column format).

2015-05-03Add support for IPv6 heuristic dissectors.Jesse Gross1-0/+2
This adds limited support for heuristic subdissectors with IPv6. The initial motivation is STT but it should transparently work for other protocols using IP heuristic dissectors in a manner similar to the non-heuristic dissectors. The limitation is in regards to IPv6 extension headers. IPv6 has multiple checks against the next protocol table when determining when the protocol is an unknown extension header or not. This assumes that the check is cheap and has no side effects, neither of which is true for heuristic dissectors. As a compromise, this assumes that the next protocol is registered as protocol, even if is not the one that is ultimately dissected. Although not strictly correct, in practice this is true for existing protocols and likely future ones because the heuristic dissectors are overriding non-heuristic ones.

2014-08-09Clean up Internet checksum handling.Guy Harris1-1/+0
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.

protocol IDs. This is substantially more efficient, which means we can build it all the time rather than only if tree (in my benchmarks the extra time taken is not large enough to be statistically significant even over tens of thousands of packets). This fixes what was probably a bug in btobex that relied on layer_names for non-tree dissection. It also enables a much simpler fix for https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9303 svn path=/trunk/; revision=53089
