SNF Command Line & SNFMulti Engine / Client Change Log
------------------------------------------------------------------------------

20080710 - Version 3.0.1

Minor change to SNFServer main.cpp:59 - removed cast to (int) which caused
a precision loss error when compiling on 64 bit systems. This changes the
thread pointer info in debug mode slightly (better).

20080626 - Version 3.0, It's official.

Changed build information.
Removed extraneous comments from configuration file.

20080524 - Version V2-9rc2.25.7

Optimized networking library for additional speed & stability by moving
receive buffer allocation from heap to stack (automatic).

Optimized timing parameters in SNFClient for improved speed. Polling dealys
are now reduced to 10ms from 30ms.

Removed speed-bug in SNFClient, 100ms guard time between retries was always
executed after an attempt (even a successful attempt). The guard time is now
condition and only fires on unsuccessful attempts.

Updated XCI server logic to ensure non-blocking sockets for clients in all
socket implementations.

20080424 - Version V2-9rc2.24.6

Refactored snfScanData.clear() to reduce heap work and fragments.

Added mutex to scanMessageFile() entry point just in case some app attempts to
put multiple threads through a single engine handler. scanMessage() is already
protected and fully wraped by the new scanMessageFile() mutex.

Added non-specific runtime exception handling to XHDR injection code.

Added 2 retries w/ 300ms delay to remove original message in XHDR inject code.
If remove fails after 3 attempts the injector throws.

Added 2 retries w/ 300ms delay to rename temp file to msg in XHDR inject code.
If rename fails after 3 attempts the injector throws.

20080416 - Version V2-9rc2.23.6

Fixed bug where SNCY open() would fail on some Win* platforms with
WSAEINVAL instead of the standard EINPROGRESS or EALREADY which were expected.
Also added WSAEWOULDBLOCK to cover other "ambiguities" in windows sockets
implementations. InProgress() on Win* now test for any of:

WSAEINPROGRESS, WSAEALREADY, WSAEWOULDBLOCK, WSAEINVAL

20080413 - Version V2-9rc2.22.6

Fixed bug in TCPHost.open() where EALREADY was not counted as a version of
EINPROGRESS. This would cause open() to throw an unnecessary exception when
an open() required extra time.

20080413 - Version V2-9rc2.21.6

Extended timeout for SYNC session open() to the full session length. This way
if a session takes a long time to open it still has a shot at success.

20080411 - Version V2-9rc2.20.6

Adjusted snfNETmgr to use non-blocking open in SYNC sessions. Open timeout
is 1/3 of the session timeout. Session timeout is 2 * Session pacing. Open
polling uses golden spiral delay from 10ms to 340ms.

20080410 - Version V2-9rc2.19.6

Adjusted XCI manager to use new snfCFGPacket paradigm in checkCFG().

Adjusted snf_RulebaseHandler::addRulePanic() to use MyMutex and eliminated
the AutoPanicMutex and waiting scheme.

Refactored scanMessage() to use a ScopeMutex() rather than lock()/unlock().

Refactored scanMessage() to use MyCFGPacket.isRulePanic() test.

Redesigned snfCFGPacket handling to automate grab() / drop() functions.

Fixed lock-up bug: Redesigned AutoPanic posting and checking mechanisms to
eliminate potential dead-lock condition. Under some conditions a precisely
timed auto-panic posting could cause the RulebaseHandler mutex and the
AutoPanicMutex to become intertwined leading to a cascading deadlock. When
this occurred all XCI processing threads and eventually the XCI listener
thread would become blocked waiting to get the current configuration.

20080409 - Version V2-9rc2.18.6

Enhanced XCI exception handling and logging to provide additional detail.

Added code to explicitely check for zero length files in scanMessagFile().
Previously a zero length file would cause the CBFR module of the filter
chain to throw an invalid buffer exception. Now if the message file is empty
scanMessageFile() will throw a FileError stating FileEmpty!.

20080407 - Version V2-9rc2.17.6

Enhanced exception reporting in snfXCImrg


20080405 - SNFServer V2-9rc2.16.6

Reduced safetly limits on status reports to 100K for status reports and 100K
for samples. Previous values were 10M. Most full sessions from the busiest
systems are < 50K total.

Recoded sendDataTimeout() to break uploads into 512 byte chunks and insert
delays only when a chunk is fragmented. This methodology improves reliability
on Win* systems without any significant penalty on systems that don't need
socket sends() to be in smaller chunks.

Fixed TCPClient::transmit() and TCPHost::transmit() bug where returned byte
count might be -1. Now returned byte counts can only be 0 or more.

20080403 - SNFServer V2-9rc2.15.5

Minor modifications to networking module to better support non-blocking open()

Updated SNFClient with new timing and non-blocking open(). Worst case return
time from SNFClient estimated at 200 seconds (theoretically impossible). No-
connection return time from SNFClient estimated at 20 seconds.

20080326 - SNFServer V2-9rc2.15.4

Refactored snfNETmgr::sync() to consolidate non-blocking io routines.

Added detailed thread status data to XCI listener thread.

Fixed minor bug in main (not changing revision), Debug flag for internal use
was left on in the last build cycle. It is commented out now.

20080325 - SNFServer V2-9rc2.14.4

Updated snfNETmgr with comprehensive thread status data.

Refactored snfNETmgr::sync() to check a Timeout, removed TCPWatchdog.

20080325 - SNFServer V2-9rc2.13.4

Upgraded TCPWatcher code to use new threading features (type, status).

20080324 - SNFServer v2-9rc2.12.4

Added a "Rulebase Getter" feature as part of the snf_Reloader. When enabled
the Rulebase Getter will launch a user defineable system() call whenever a
new rulebase file is available. The call will be repeated until the condition
is cleared by a successful update of the rulebase file. The Rulebase Getter
will wait a configurable "guard time" between attempts. The default system()
call is "getRulebase" with a guard time of 3 minutes. In most cases this will
launch the provided getRulebase script which should be present in the start
location of SNFServer on most systems. Best practice is to configure the full
path to the update script. The system() call is made in a separate thread so
that if the system() call hangs for some reason only the Rulebase Getter is
stuck.

Built thread monitoring function for SNFServer.exe (Full status report / sec).
The thread monitoring report is turned on when the program is renamed to
SNFDebugServer.exe or if "debug" appears in the file path to the program.

Refactored XCI channels to leverage new thread monitoring.

Refactored Threading to eliminate inline code.

Improved exception handling/reporting in scanMessageFile().

Updated scanMessagFile() header injection code to accommodate messages with
no body. Previous version would throw an exception when it could not find an
injection point. The new version makes the injection point byte 0 and puts
the injected headers at the top of the message using it's best guess about the
type of line endings (CRLF or LF) to use.

Updated Threading library to include high level thread state tracking and
naming. Also creates a global Threads object that can produce a real-time
status report on all threads.

Updated Networking library to use SO_REUSEADDR by default on listeners.

20080318 - SNF2-9rc1.11.exe Consolidated several mods/fixes

Corrected scan error logging bug. Was posting <s/> now posts <e/>.

Updated scan error logging to be more uniform with non-scan errors.

Developed various script prototypes for postfix integration & automated
updates on win* systems using the new UpdateReady.txt file mechanism.

Fixed a bug in scanMessageFile() where an \n\n style insertion point
would never be detected.

Modified scanMessageFile() header injection to strip <CR> from line ends
when the message file provided does not use them. The line-end style of
the message file is detected while locating the insertion point. If the
insertion point (first blank line) does not use <CR><LF> then the SNF
generated X-Headers are stripped of <CR> in a tight loop before injection.

Enhanced error and exception reporting in SNFMulti.cpp scanMessageFile().

Enhanced exception handling in networking module. All exceptions now
throw descriptive runtime_error exceptions.

20080306 - SNF2-9rc1.8.exe (FIRST RELEASE CANDIDATE for VERSION 3!)

Added Drilldown Header Directive Functions - When the candidate source IP
comes from a header matching a drilldown directive the IP is marked "Ignore"
in GBUdb and the candidate is no longer eligible to be the source for that
message. This allows SNF to follow the trusted chain of devices (by IP) down
to the actual source of the message. It is handy for ignoring net blocks
because it can match partial IPs but it is designed to allow SNF to learn
it's way through the servers at large ISPs so that the original source for
each message can be evaluated directly.

Added Source Header Directive Functions - This feature allows SNF to acquire
the source IP for a message from a specific header rather than searching
through the Received headers in the message. This is useful when the original
source for a message is not represented in Received headers. For example:
Hotmail places the originating source IP in a special header and does not
provide a Received header for that IP. This feature is protected from abuse
by a "Context" feature which only activates the source header directive when
specific content is found in a specific received header. Using the above
example, this feature can be configured so that a Hotmail source header would
only be read if the top Recieved header contained "hotmail.com [" indicating
that the ptr lookup for the header matched the hotmail domain. Note: When a
source is pulled from a header directive that source is put into a synthetic
Received header and injected into the scanning stream (not the message) as
the first Received header.

Added forced source IP to XCI - It is now possible to "inject" or "force"
the source IP for any message by providing that IP in the XCI request or
directly in a scan...() function call. This allows the calling application
to provide the source IP for a message ahead of any Received headers that
might be in the message. This is useful when the calling application knows
the original source IP for the message but that IP is not represented in
the Received headers and it is not desireable to use the Source Header
Directive mechanism.

Added forced source IP mode to SNFClient - It is now possible to call the
SNFClient utility with an IP4Address using the syntax:

SNFClient -source=12.34.56.78

The -source mode of SNFClient exercises the forced source IP feature in
the XCI (see above)

Added Status Report features to SNFClient and XCI - It is now possible to
request the latest status.second, status.minute, or status.hour data via
the XCI and SNFClient. The syntax for requesting a status report using the
SNFClient is:

SNFClient -status.second
SNFClient -status.minute
SNFClient -status.hour

In addition to providing status reports the SNFClient in this mode will
return a nonzero value (usually 99) if it is unable to get a status report
from SNFServer. This feature can be used to verify that SNFServer is up
and responding. If SNFServer is OK then the result code returned is 0.

Added result codes to SNFClient -test and XCI IP test functions - The XCI
engine has been upgraded to provide the range value for the IP under test
as well as the symbolic result code associated with that range. This allows
the -test function to provide results that are consistent with the GBUdb
configuration without additional processing: For example, if the IP falls
in the Caution range then the Caution result code will be returned just
as if a message had been scanned with the same IP and no pattern match
occurred. The same is true for Truncate and Black range hits.

Added Timestamp and Command Line Parameter data to SNFClient.exe.err - When
an error occurs with SNFClient that may not appear in the SNFServer logs an
entry is appended to the SNFClient.exe.err file. That in itself is not new.
The new feature is that the entries added to the SNFClient.exe.err file now
include timestamp and command line data to aid in debugging.

Added BIG-ENDIAN Conversion - When the SNFServer program is compiled on a
system that uses a BIG-ENDIAN processor (such as a power-mac) the rulebase
load process now includes a routine to convert the token matrix from it's
native LITTLE-ENDIAN format to a BIG-ENDIAN format. This solves a bug where
Power-Mac (and presumably other BIG-ENDIAN systems) could compile and run
the SNF* software but were unable to capture spam because the token matrix
in the rulebase file was misinterpreted.

Note: The BIG-ENDIAN Conversion feature is still considered experimental
because it has not yet been thoroughly tested.

Updated the Configuration Log to include all of the current configuration
features and to improve it's readability.


20080207 - SNF2-9b1.7.exe

SYNC Timeout now 2x SYNC Schedule

SNFServer now produces an UpdateReady.txt file when the UTC timestamp on
the SYNC server is newer than the UTC timestamp of the active rulebase. It
is presumed that a suitable update script or program will run periodically
and download a fresh rulebase file if the UpdateReady.txt file is present.
The update script should remove the UpdateReady.txt file when it completes
a successful download of the new rulebase file.

Added available rulebase UTC in status reports <udate utc.../>

Added Automatic path fixup for ending / or \

Added option to use local time in log rotation <rotation localtime='no'/>
The default is still utc.

20071102 - SNF2-9b1.6.exe

Increased MAX_EVALS from 1024 to 2048.

Adjusted defult range envelopes in snf_engine.xml to be more conservative.

20071017 - SNF2-9b1.5.exe

Added a missing #include directive to the networking.hpp file. The
missing #include was not a factor on Linux and Windows systems but
caused compiler errors on BSD systems.

Corrected a bug in the GBUdb White Range code where any message with a
white range source IP was being forced to the white result code. The
engine now (correctly) only forces the result and records the event when
a black pattern rule was matched and the White Range IP causes that
scan result to be overturned. If the scan result was not a black pattern
match then the original scan result is allowed to pass through.

Corrected a bug in the Header Analysis filter chain module that would
cause the first header in the message to be ignored in some cases.

Corrected an XML log format problem so that <s/> elements are correctly
open ended <s ....> or closed (empty) <s..../> according to whether they
have subordinate elements.

Adjusted the GBUdb header info format. The order of the Confidence
figure and Probabilty figure is now the same as in the XML log files
(C then P). The confidence and probability figures are now preceeded
with c= and p= respectively so that it's easy to tell which is which.

20071009 - SNF2-9b1.4.exe

Tightened up the XCI handler code and removed the watchdog. The watchdog
would restart the listener if there were no connections in 5 minutes. It
was originally added to provide additional stability, however in practice
there have been no "stalled listeners". Also, a stalled listener would
likely be a sign of a different problem that the watchdog would tend to
hide.

Modified and refactored the XCI configuration management code. All XCI config
changes and up-down operations are now handled in a single function except
upon exit from the main XCI thread where XCI_shutdown() is always called.

Added some more detailed exception handling code to the XCI component so that
more data will be logged in the event of an error.


20071008 - SNF2-9b1.2.exe

Added support for passing Communigate Message Files directly. Communigate adds
data to the top of the message file. That data stops at the first blank line and
the rfc822 message begins. The SNFServer engine can now be told to ignore this
extra data using the following option:

<msg-file type='cgp'/> <!-- type='cgp' for communigate message files -->

If the msg-file type is anything other than 'cgp' then it will treat the message
file as a standard rfc822 message in the usual way. The default setting is

<msg-file type='rfc822'/>
