Changelog

  • Fixed long-standing bugs in transcoding the following data types when their sizes differ: signed integers with negative values, doubles, and fixed-size strings and octet-arrays. This may introduce inconsistencies when tools are compiled with different versions of libfixbuf.
  • Changed libfixbuf to reject a template and return an error when it receives a template that uses an invalid length for an element. Previously libfixbuf printed a warning and accepted the template.
  • Added support for a hexdump argument to the --string-format and --octet-format switches of ipfixDump.
  • Fixed a bug from 3.0.0.alpha1 where NTP-encoded time values were not decoded correctly by fbRecordGetValueForField() and similar functions.
  • Changed fbSubTemplateMultiListEntryClear() to zero the tmpl and tmplID members.
  • Changed fbDecodeBasicList() to free and reallocate its memory on each call.

Changelog

  • Made many changes to functions and public structs that break compatibilty with previous releases of libfixbuf.
  • Changed fbTemplate_t to reference a new object type, fbTemplateField_t, resulting in changes to many function signatures. The TemplateField includes the offset of the element's value, making it easier to get a value from a record.
  • Changed and removed members of fbInfoElement_t. Added several macros to get values from an fbInfoElement_t.
  • Added a new type, fbTemplateInfo_t, to hold the name and description of a Template and additional information about it. A TemplateInfo contains a SubTemplateList of fbBasicListInfo_t, a new type to describe the information element IDs of a BasicList and of the element it contains.
  • Changed fbSessionAddTemplate() to take an additional parameter: an fbTemplateInfo_t, which may be NULL. fbSessionAddTemplateWithMetadata() has been removed.
  • Changed fbSessionSetMetadataExportTemplates() to take an additional paramter: the template ID for the fbBasicListInfo_t.
  • Removed support for the Spread Toolkit.
  • Renamed the following functions: fBufSetAutomaticInsert() to fBufSetAutomaticElementInsert(), fBufSetAutomaticMode() to fBufSetAutomaticNextMessage(), fbBasicListRealloc() to fbBasicListResize(), fbListValidSemantic() to fbListSemanticsIsValid(), fbSubTemplateListRealloc() to fbSubTemplateListResize(), fbSubTemplateMultiListEntryRealloc() to fbSubTemplateMultiListEntryResize(), fbSubTemplateMultiListRealloc() to fbSubTemplateMultiListResize(), and fbTemplateGetIndexedIE() to fbTemplateGetFieldByPosition().
  • Removed functions fbBasicListInitWithOwnBuffer(), fbSessionEnableTemplateMetadata(), fbSessionEnableTypeMetadata(), and fbSubTemplateListInitWithOwnBuffer().
  • Removed fbInfoModelTypeInfoRecord() and fbTemplateMetadataRecord(). Added a replaced function, fbTemplateIsMetadata(), that checks whether a Template is for describing metadata: RFC5610 records (Info Element descriptions) or Template metadata.
  • Removed macros FB_IE_BASIC_LIST, FB_IE_SUBTEMPLATE_LIST, and FB_IE_SUBTEMPLATE_MULTILIST.
  • Changed the members of fbSubTemplateList_t.
  • Made major changes to the output of ipfixDump, and modified many of its command line switches.
  • Added a new type, fbRecord_t, that holds the data for a record read from a stream and the Template that describes that data. Added functions, fBufNextRecord() and others, to support the new type and get values from a fbRecord_t.
  • Added a function to copy an fbRecord_t from one fbTemplate_t to another.
  • Added a new command line tool, ipfix2json, to convert an IPFIX file to JSON. This tool is built by default; use --disable-tools to build the library only.
  • Updated the ABI to use 'const' on more parameters and more return values.
  • Added new convenience functions, fbSessionAddTemplatesForExport() and fBufSetTemplatesForExport(), that handle adding or setting both the internal and export templates.
  • Added convenience functions to copy an incoming templates to an export Session.
  • Added a new function, fbBasicListInitWithLength(), to initialize a BasicList and use reduced length encoding for the element.
  • Added convenience macros fbBLNext(), fbSTLNext(), fbSTMLNext(), and fbSTMLEntryNext() for iterating over fbBasicList_t, fbSubTemplateList_t, fbSubTemplateMultiList_t and fbSubTemplateMultiListEntry_t objects.
  • Added a Template iterator, fbTemplateIter_t, to visit the TemplateFields in a Template.
  • Added functions to copy and compare Templates. Added functions to find an element in a Template and return a TemplateField.
  • Added a function to set the context object on a Template.
  • Added an enum for the Information Element semantics, fbInfoElementSemantics_t. Added an enum for the structured data (list) semantics, fbListSemantics_t.
  • Changed license to GNU General Public License (GPL) Version 2, June 1991.
