Re: Barnyard2 2-1.13-BETA
From: beenph <beenph () gmail com>

Greetings Everyone,

We did commit a little fix/feature add  in 2-1.13-BETA (Build 326)

It has been asked by quite a few users to enable SIGHUP,SIGUSR1 to be
available for barnyard2, well this time has come.

It also fixes a few minor issue, error compiling when --enable-debug
was used, fixes a few literals, fixes rpm spec file (for future
release).

While its currently not upstream it will get when tested, thus I
encourage people who would like to give it a HUP trust to
try it out, especially people who update their signature often.

Source tree: https://github.com/binf/barnyard2/tree/fix-signals

Commit message:
<SNIP>
Last minute commit for a long waited needed feature and some little fix. …

Add: Support for proper signal handling.

Fixed: Compile issue when debug was enabled (missing , in some
DEBUG_WRAP code.

Fixed: Changed a few places where the snort literal was used instead of
barnyard2 and this could confuse some first time barnyard2 users.

Fixed: RPM spec file to point to good version (when needed)

Bumped: Build to 326
</SNIP>

Cheers,
-elz

Greetings everyone,

 We are happy to announce the Availability of Barnyard2 2-1.13-BETA
 which can be downloaded from HERE: https://github.com/firnsy/barnyard2.git


This release is a bug fix release that also introduce a few new
 features and enhancements


 =====================
 UPGRADING REQUIREMENT
 =====================
 ----------------------
 If you are upgrading to barnyard2 2-1.13 Build 325 or above from a
 previous version  that is not 2-1.13 and using the output database.

***** We highly recommend ******
 To delete every row in your sig_reference table. (DELETE FROM sig_reference;)
 The table will be re-populated at  process startup, and has no impact
on historical data.

 =====================
 UPGRADING REQUIREMENT
 =====================





 Feature request:
 ----------------
 Phil Daws:        Add interface and hostname field to spo_alert_csv if
                          specified.
 Jorge Pinto:      spo_syslog_full support for ASCII,BASE64 payload

 Jason Brvenik:  variables .....(a long time ago, sorry :P)

 Martin Olsson:  Remove some useless verbosity unless
                         ./configure --enable-debug is specified and proper
                          flag are used (spo_database and sid-msg.mapv2)

 *And all other barnyard2 users who help and contribute.

 Bug report:
 -----------
 Martin Olsson:              - bug in sig_reference generation and good
                                        discussions.

 John Eure and others   - autogen.sh could cause some issue on some system so
                                        [autoreconf -fv --install] is
not set to autoreconf -fvi

 John Naggets               - spo_database: could stop barnyard2 from
                                         processing new event if some
packets with ip
                                         option where processed and
option_len  was null.

 Fäbu Hufi                     - spo_syslog_full: in complete mode was
                                        printing wrong ip version
information and ip header length.

*And all other barnyard2 users who help and contribute.


 New feature:
 ------------


 Support for sid-msg.map Version 2 format.
 -------
 A new sig-msg.map format can be generated by pulledpok (upcoming release,
 already in svn). Detection of sid-msg.map version is done by a simple
 header in the  file that shouldn't be altered if you want it to be
processed correctly.

 sig-msg.map version 2 format extend the information already present in
 the sid-msg.map file created from rules.

This new format version allow signature  pre-population if users are
using output database method with  barnyard2 2-1.13 and above.
 ______________________
 sid-msg.map v1 format:
 ______________________
 SID || MSG || REF 1 || REF N
 sid := integer
 msg := string
 ref := string
 ______________________
 sid-msg.map v2 format:
 ______________________
 GID || SID || REV || CLASSIFICATION || PRIORITY || MSG || REF 1 || REF N
 gid := integer
 sid := integer
 rev := integer
 classification := string (if NULL set to NOCLASS)
 priority := integer (if prio == 0, classification priority is used)
 msg := string
 ref := string
 =====================
 generator (GID, gen-msg.map) are defaulted to the following value
 if their information is not overruled in sid-msg.map v2 file via
 processing of preprocessor.rules:
 revision 1
 classification 0
 priority 3
 If generator message is present in the sid-msg.map v2 file, and
 gen-msg.map message are longer
 (more comprehensive by string length),
 gen-msg.map messages are used instead of sid-msg.map v2 file
generator messages.
 =====================
  -------


Signature/event logging suppression at spooler level
 -------
 Read doc/README.sig_suppression
 configuration file Variables:
 -------

Barnyard2 configuration Variables
  -------
 You can now use [var VARNAME value] in the barnyard2 configuration
 file and every
  instance of $VARNAME will get replaced by value.
  Note that variable declaration order is important only you include a
 variable in a variable.
  EX (is VALID):
  var INTERFACE ethX
  var PATH /var/log/IDS
  var LOG $PATH/$INTERFACE/log
  var ARCHIVE $PATH/$INTERFACE/archive
  EX (is INVALID):
  var LOG $PATH/$INTERFACE/log
  var ARCHIVE $PATH/$INTERFACE/archive
  var INTERFACE ethX
  var PATH /var/log/IDS
  -------

new output database configuration keyword
 -------

 Keywords connection_limit and reconnect_sleep_time where added in
 2-1.10 but where "undocumented" and shouldn't be modified unless
 you encounter connectivity issue.

 connection_limit <integer>: default 10  - The maximum number of time
                                           that barnyard2 will
tolerate a transaction
                                           failure and or database
connection failure.

 reconnect_sleep_time <integer> : default 5 - The number of seconds to sleep
                                              between connection retry.

 disable_signature_reference_table - Tell the output plugin not to synchronize
                                     the sig_reference table in the schema.
                                     This option will speedup the process,
                                     especially if you use sid-msg.mapv2
                                     file or  have a lot of signature already
                                     in databases. (Make sure that you
do not need that
                                     information before enabling this)
