And here's a slightly cleaned up version.
5) Support for the AUDIT target has been added. AUDIT is a feature of
the 2.6.39 kernel and iptables 1.4.10 that allows security auditing
of access decisions.
Note: This support note is the only documentation of this support
currently available.
The support involves the following:
a) A new "AUDIT Target" capability is added and is required for
auditing support. To use AUDIT support with a capabilities
file, that file must be generated using this or a later
release.
Use 'shorewall show capabilities' after installing this release
to see if your kernel/iptables support the AUDIT target.
b) In /etc/shorewall/policy's POLICY column, the policy (and
default action, if any) may be followed by ':audit' to cause
application of the policy to be audited.
Only ACCEPT, DROP and REJECT policies may be audited.
Example:
#SOURCE DEST POLICY LOG
# LEVEL
net fw DROP:audit
It is allowed to also specify a log level on audited policies
resulting in both auditing and logging.
c) Three new builtin actions that may be used in the rules file,
in macros and in other actions.
AACCEPT - Audits and accepts the connection request
ADROP - Audits and drops the connection request
AREJECT - Audits and rejects
A log level may be supplied with these actions to
provide both auditing and logging.
Example:
AACCEPT:info loc net ...
d) The BLACKLIST_DISPOSITION, MACLIST_DISPOSITION and
TCP_FLAGS_DISPOSITION options may be set as follows:
BLACKLIST_DISPOSITION ADROP or AREJECT
MACLIST_DISPOSITION ADROP
AREJECT, unless
MACLIST_TABLE=mangle
TCP_FLAGS_DISPOSITION ADROP or AREJECT
