Routines that don't take a tvbuff as an argument shouldn't have tvb_ in the name. Change-Id: I3550256551e30b3f329cbbfca71ef27c727d29c0 Reviewed-on: https://code.wireshark.org/review/7302 Reviewed-by: Guy Harris <guy@alum.mit.edu>
2015-02-11Combine SSE and pre-compiled patterns for faster pbrkHadriel Kaplan1-1/+1
This combines the SSE4.2 instructions usage, with pre-compiled pattern searching usage, for a faster pbrk search method. Testing against large files of HTTP and SIP, there is about a 5% performance improvement by using pre-"compiled" patterns for guint8_pbrk() instead of passing it the search string and having it build the match array every time. Similar to regular expressions, "compiling" the pattern match array in advance only once and using the "compiled" patterns for the searches is faster than compiling it every time.

2013-09-07- no need for a doubly-linked list of TVBs, single is simplerEvan Huus1-1/+0
- support merging chains in tvb_add_to_chain - when we have an old reassembled TVB, just merge the chains rather than freeing it (we may still need it as it may already be a data source) - modelines Fixes https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9027 #BACKPORT, but it's gonna be messy... svn path=/trunk/; revision=51825

2013-07-10tvbuff: replace type with operation vtableJakub Zawadzki1-1/+14

2013-04-20When we're dissecting the beginning of a fragmented packet that weGuy Harris1-6/+6
haven't reassembled, we're probably moving sequentially through the packet, which means that we'll run past the end of the fragment rather than past the end of what would have been the reassembled packet had we reassembled it. I.e., there's little reason to care whether we're past the end of the fragment but not past the end of the packet, or whether we're past the end of the packet; in either case, we're past the end of the fragment, and if somebody wants to know whether the packet is malformed by stopping short of certain fields, they should enable reassembly. So we get rid of the explicit fragment length in tvbuffs and, instead, have a "this is a fragment" flag; if that flag is set, we throw FragmentBoundsError rather than ReportedBoundsError if we run past the end of the reported data. (This also means we could flag the tvbuff even if we don't know how large the reassembled packet will be, e.g. when doing IP reassembly.) Replace tvb_new_subset_length_fragment() with tvb_new_subset_length() and a new "set the "this is a fragment flag"" routine. svn path=/trunk/; revision=48940
2013-04-18Add to tvbuffs a "fragment length" field; if the tvbuff represents theGuy Harris1-0/+6
first fragment of a non-reassembled packet, and we know the length the packet would have if it were reassembled, this field holds the length of the fragment, and the "reported length" field shows the length the packet would have if it were reassembled, so going past the end of the fragment but staying within the length of the reassembled packet can be reported as "dissection would have worked if the packet had been reassembled" rather than "the packet is too short, so it was probably malformed". Add a FragmentBoundsError exception, thrown in the "dissection would have worked if the packet had been reassembled" case. Add a new tvb_new_subset_length_fragment() routine to create a new subset tvb with specified fragment and reported lengths. Use it in the CLNP dissector. Add some more sanity checks in the CLNP dissector. svn path=/trunk/; revision=48917

2011-12-21A simplified version of tvbuffs:Bill Meier1-6/+4
- Essentially no changes from current dissector de facto tvbuff usage; - Do away with 'usage_counts' and with 'used_in' GSLists; - Manage tvb chains via a simple doubly linked list. - API changes: a. tvb_increment_usage_count() and tvb_decrement_usage_count() no longer exist; b. tvb_free_chain() can only be called for the 'top-level' (initial) tvb of a chain) or for a tvb not in a chain. c. tvb_free() now just calls tvb_free_chain() [should have no impact on existing dissectors]. svn path=/trunk/; revision=40264
