Drop maintainership.

irc.d script for security/snort

        This is a sample script for ${PREFIX}/etc/rc.d that will
        wake snort up on boot, and take it down on shutdown. Nothing
        fancy here.  This is needed, because I'm planning on teaching
        ACID many new things, and ACID expects snort to help itself.
        There is only one thing that requires thinking here: This
        should run only after {MySQL|PostgreSQL} server is up, as
        snort might want to report to the local server.

Update to snort 2.0.1

Fix detection of sparc64.

Fix a couple of typos.

Update to snort 2.0.0.  This fixes a security vulnerability:

  The Sourcefire Vulnerability Research Team has learned of an integer
  overflow in the Snort stream4 preprocessor used by the Sourcefire
  Network Sensor product line. The Snort stream4 preprocessor
  (spp_stream4) incorrectly calculates segment size parameters during
  stream reassembly for certain sequence number ranges which can lead to
  an integer overflow that can be expanded to a heap overflow.

Update to snort-1.9.1.  This is an important security update:

A buffer overflow has been found in the snort RPC normalization
routines by ISS X-Force. This can cause snort to execute
arbitrary code embedded within sniffed network packets. This
preprocessor is enabled by default.

Chase libpq version bump.

Update to snort 1.9.0.  Tweak the default config files so it can actually
find its installed ruleset [1].  Install config files by default if there is
not already one present, and remove on deinstall if they are unchanged
from the default.

#include <sys/param.h> instead of <machine/param.h> to fix build on
-current.

Upgrade to snort 1.8.6.  The previous two versions (1.8.4 and 1.8.5) were
buggy and short-lived; hopefully this one is better.

Update to snort 1.8.3, a stability and bugfix release.    

Update to snort 1.8.2, a bugfix/stability release.    

Remove a stray line-continuation which was breaking the fetch.

Fix WITH_MYSQL, WITH_ODBC and WITH_POSTGRES.    

-pthread --> ${PTHREAD_LIBS}   -D_THREAD_SAFE --> ${PTHREAD_CFLAGS}    

Upgrade to 1.7.    

Set reasonable defaults for mysql, postgresql and odbc support so   the package
dependencies aren't screwed up in case a package is   installed but the
corresponding WITH_* option isn't given.    

Switch from mysql322-{client,server} to mysql323-{client,server}.    

Add additional options (WITH_FLEXRESP, WITH_MYSQL, WITH_ODBC   and
WITH_POSTGRES).    

Convert category security to new layout.  

Upgrade to 1.6.3.    

Upgrade to 1.6.2.2.    

Remove redundant/inappropriate CATEGORIES.  People need to start reading   the
Porter's Handbook.  :-)
