SNFMultiSDK_Windows_Base/ChangeLog.txt

+20200623 Engine 3.2.2 Removed saccades
+
+20200623 latest CodeDweller - all MIT license now
+
+20191104 Updated copyright notice
+
+20160418 Bumped tiny revision for buffer allocation bug fix in
+CodeDweller configuration.cpp
+    
+20151223 Version Number Change.
+    
+20151223
+
+* Replaced White-Guard algorithm with Strangers algorightm.
+
+* Updated version number of SNFMulti.
+
+20151216 Tightened up evaluator code to eliminate un-necessary
+attempts to match precise tokens.
+
+20140610 Fixed the Black X-header so that it ignores above-band result
+codes.  Incremented the very minor engine revision number.
+
+20140512 Updated version number to go along with updates to the
+engine. There are no real changes with the SNFServer code, but this
+number update will remove confusion about whether the SNFServer engine
+is up to date with the fairly significant changes in the underlying
+engine.
+
+20140507
+
+* Fixed warning where a Mutex passed to GBUdbRecordLockingShim() by
+  value should have been passed by reference. (reference to stack
+  allocated object)
+
+* Bumped minor revision on the engine -- now 3.1.2.
+
+20140502
+
+* Implemented WhiteGuard
+* Updated engine revision number
+
+20140212 Implemented AI based "saccades" engine to improve scanning
+efficiency. The Saccades engine borrows from vision systems research
+and allows SNF to learn important message structures and adapt it's
+scanning technique in real-time. Using this engine SNF can often avoid
+scanning large portions of each message without missing important
+content resulting in potentially 10 fold improvements in scanner
+efficiency.
+    
+20140124
+
+* Further optimized deep code in the scanning engine using a jump
+  table to replace a collection of if/else logic.
+
+* Updated some of the related code using more modern and/or correct
+  coding practices.
+
+20140119 Improved time tracking / reporting.
+
+20131203 Minor revision tick.
+    
+20131203 Bug Fix: Corrected Timestamp() formatting.
+    
+20131203 Bug Fix: Updated Timestamp() to use C++ stringstream and to
+handle possible null pointer from gmtime()
+
+20131022
+
+* Remove dependency on config.h.
+    
+* Hard-code version to 3.0.
+
+20121121
+
+* Fixed a bug in scanMessageFile where the XHDRInjectOn flag was being
+  interpreted before it had been set by the configuration This caused
+  large messages to be rewritten shorter than they needed to be when
+  header injection was turned on because the flag would appear to be
+  off and the MessageFileSize would be recalculated downward. Later,
+  after the flag was set, the headers would be injected into the
+  shortened file.
+    
+* Added a function to snf_RulebaseHandler that safely peeks at the
+  current configuration to facilitate the above bug fix.
+    
+* Bumped the minor revision number for the engine.
+
+20121120
+
+* Improved code quality for logic that shrinks the message size when
+  header injection is turned off.
+    
+* Bumped minor revision number.
+    
+20121022 Corrected a bug where match records were not recorded in the
+ScanData.  Updated engine minor version.
+
+20121001 Fixed subtle bug where normal XCI responses did not end with
+\n.  Updated engine version number to 3.0.20.
+    
+20120930 Changed boolean to bool at 986 and 987 - bool is the correct
+type specifier for C++ and this was causing errors on one of the
+labrat compilers. No idea why it worked perfectly on mingw!
+    
+20120928
+
+* snf_EngineHandler::scanMessageFile updated to read only up to the
+  scan horizon of large files if possible (when header injection is
+  turned off)
+    
+* snfXCImgr now has 8 processing channels.
+    
+* Engine Version number changed.
+    
+20120326 Changed minor revision number to reflect rebuilding the
+engine with new CodeDweller networking bug fixes.
+
+20120326 Dropped E3.0.17 binary, added E3.0.18 binary.
+
+20110505 Committing candidate SNFServer with refined SNFMulti code
+covering rule panic handling and pattern match voting.
+
+20110505 Reworked rule voting code to clarify and bring the code
+closer to current standards. This was part of researching a potential
+problem involving the voting of panicked rules and this rebuild has
+verified that there is no problem --- panicked rules are indeed inert
+as intended.
+    
+20110219
+
+* Fixed bug where only one of multiple source header directives with
+  the same source header definition would be recognized. The fix was
+  to improve the comparator function for HeaderFinderPattern so that
+  it included context. Prior to that only one source header definition
+  would be recognized because the ordinal is always 0 for source
+  headers. As a result, only the first context could be registered.
+    
+* Refactored HeaderFinder::CheckContent() to improve the coding style
+  and make use of a switch().
+    
+* Corrected a bug in HeaderFinder::CheckContent that would allow a
+  header forced source IP to be set multiple times. Now it will only
+  be set when the first event where all of the conditions are
+  satisfied. Bug was that the test that the source had already been
+  set was looking at the source IP which is actually never set until
+  the actual message scan begins (after header directives have already
+  been evaluated).
+    
+* Changed SNFMulti revision to 16.
+
+20100614
+
+* Fixed bug in FilterChainBase64 where an extra character would be
+  returned if the module ran out of data in SCANNING mode. Now if this
+  occurs a flag is set and "No More Data" is thrown instead of
+  returning the extra byte.
+    
+* Adjusted DEFUNKER preamble in code to indicate spaces in front and
+  back since newlines would be converted to spaces by the outer shell
+  of FilterChainDefunker.
+    
+* Adjusted engine update number to .15 - now at Version 3.0.15
+
+20100531
+
+* Changed engine update number to .14 (now Version 3.0.14).
+
+* Modified FilterChainDefunker to avoid recursion when eating (X)HTML
+  tags. Now there is a new mechanism that allows deeper states to
+  return nothing (no conversion) by setting a boolean flag. The result
+  is that the root state will skip that result and try again with the
+  next available byte in a simple loop (no recursion). This eliminates
+  a vulnerability where a message constructed with deeply embeded /
+  chained (X)HTML tags could cause the system to run out of stack
+  space under some conditions.
+
+20100405
+
+* Fixed bug in scanMessageFile where a very short message file could
+  cause the exception: ERROR_MSG_XHDRi: Begin vector::_M_range_check
+    
+* Changed version to 3.0.13
+
+20100318 Fixed bug in GBUdbIgnoreList reader to prevent reading
+outside of the line buffer.
+
+20091103 Fixed bug in snfCFGmgr where OEM provided license ID was not
+always captured in the configuration data causing SYNC authentication
+problems.  Updated version to 3.0.12.
+
+20090821 Fixed memory leak when failing to authenticate a rulebase
+file.
+
+20090730
+
+* Moved persistent state aux store() operations to RecordSyncEvent
+
+* Changed DiscLogger wait time to 1 second
+
+* New engine version number 3.0.10
+
+20090724 Updated mingwm10.dll. New SNFServer build requires newest
+mingwm10.dll (see notes on version problems discovered when building
+snfmulti.dll project)
+
+20090724 Changed engine revision to 3.0.9 after networking SIGPIPE bug fix.
+          
+20090707 SNFMulti engine now at 3.0.8 after several small bug fixes.
+
+20090707 Fixed valgrind complaint about using uninitialized data when
+generating a OneTimePad. The algorithm uses unsigned char x as a
+register. Each next random byte in the pad is based on encrypting the
+last-- so a first byte is needed. Original code used an uninitialized
+x on purpose in order to get a supposedly unpredictable byte out of
+RAM. To make valgrind happy (and truly to make the algorithm better) x
+is now initialized by encrypting a 0 with the pad generator. This
+value is not directly exposed in the generated pad. The first byte in
+the one time pad is not the result of encrypting 0 but instead the
+result of encrypting the result of that operation. So, the first byte
+is based on the state of the pad generator just prior to making the
+OneTimePad. This is probably harder to predict than the state of the
+stack (where x would have come from) anyway.
+
+20090707
+
+* Fixed persistent state data bug. Persistent state data is now saved
+  once per second after updating status logs.
+
+* Improved snfLOGmgr d'tor so that final persistent state data is only
+  saved (attempted) if snfLOGmgr has been Configured.
+    
+20090707
+
+* Fixed initialization of time trigger (typo) was 846... now
+  864... Supposed to be "once per day".
+
+* Fixed missing initialization of Configured(false).
+
 20090707 Upgraded Engine to SNFMulti V3.0.8 (contains minor bug fixes).
 
 20090704 Getting closer - new DLL, new features, a little polish.
