2018-04-20Handle subset tvbuffs where the length goes past the end of the parent.Guy Harris1-12/+15
Add a "contained length" to tvbuffs. For non-subset tvbuffs, that's the same as the reported length. For a subset tvbuff, that's the amount of the reported data that was actually present in the "contained data" of the parent tvbuff. This is unaffected by the *captured* length of any tvbuff; that differs from the contained length only if the capture was cut short by a snapshot length. If a reference is within the reported data, but not within the contained data, a ContainedBoundsError exception is thrown. This exception represents a protocol error, rather than a reference past the captured data in the packet; we treat it as such.

2017-12-08Have the frame_tvbuff.c routines not use the global cfile.Guy Harris1-21/+20
Have the routines that create them take a pointer to a struct packet_provider_data, store that in the tvbuff data, and use it to get the wtap from which packets are being read. While we're at it, don't include globals.h in any header files, and include it in source files iff the source file actually uses cfile. Add whatever includes that requires.

2017-12-08Move the frame_set stuff back into the capture_file structure.Guy Harris1-5/+5
libwireshark now expects an epan_t to be created with a pointer to a "packet provider" structure; that structure is opaque within libwireshark, and a pointer to it is passed to the callbacks that provide interface names, interface, descriptions, user comments, and packet time stamps, and that set user comments. The code that calls epan_new() is expected to provide those callbacks, and to define the structure, which can be used by the providers. If none of the callbacks need that extra information, the "packet provider" structure can be null. Have a "file" packet provider for all the programs that provide packets from a file.

2015-02-11Combine SSE and pre-compiled patterns for faster pbrkHadriel Kaplan1-2/+2
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.

In particular, epan/wslua/lrexlib.c has its own buffer_ routines, causing some linker warnings on some platforms, as reported in bug 10332. (Not to be backported to 1.12, as that would change the API and ABI of libwsutil and libwiretap. We should also make the buffer_ routines in epan/wslua/lrexlib.c static, which should also address this problem, but the name change avoids other potential namespace collisions.)

Start of refactoring Wiretap and breaking structures down into "generally useful fields for dissection" and "capture specific". Since this in intended as a "base" for Wiretap and Filetap, the "wft" prefix is used for "common" functionality. The "architectural" changes can be found in cfile.h, wtap.h, wtap-int.h and (new file) wftap-int.h. Most of the other (painstaking) changes were really just the result of compiling those new architecture changes. bug:9607 Change-Id: Ife858a61760d7a8a03be073546c0e7e582cab2ae Reviewed-on: https://code.wireshark.org/review/1485 Reviewed-by: Michael Mann <mmann78@netscape.net>

(https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9607) This is a VERY PRELIMINARY version of tfshark. It's an attempt to jumpstart FileShark and its architecture. Right now it's mostly just a very stripped down version of tshark with all of the necessary build modifications (including now building filetap library since tfshark depends on it) This code has helped me identify what I believe to be all of the necessary layers for a complete fileshark architecture.
