This patch adds an IPFIX output plugin to ulogd2. It generates NetFlow/IPFIX
traces and sends them to a remote server (collector) via TCP or UDP.
Based on original work by Holger Eitzenberger <holger@eitzenberger.org>.
How to test this
----------------
I am currently testing this with the NFCT input and Wireshark.
Place the following in ulogd.conf:
# this will print all flows on screen
loglevel=1
# load NFCT and IPFIX plugins
plugin="/lib/ulogd/ulogd_inpflow_NFCT.so"
plugin="/lib/ulogd/ulogd_output_IPFIX.so"
stack=ct1:NFCT,ipfix1:IPFIX
[ct1]
netlink_socket_buffer_size=217088
netlink_socket_buffer_maxsize=1085440
accept_proto_filter=tcp,sctp
[ipfix1]
oid=1
host="127.0.0.1"
#port=4739
#send_template="once"
I am currently testing it by launching a plain NetCat listener on port
4739 (the default for IPFIX) and then running Wireshark and see that it
dissects the IPFIX/NetFlow traffic correctly (obviously this relies on
the Wireshark NetFlow dissector being correct).
First:
nc -vvvv -l 127.0.0.1 4739
Then:
sudo ulogd -vc ulogd.conf

This patch introduces a new JSON output plugin. This
patch displays CIM field name instead of ulogd key valu
if this CIM field is available.
The module does not display binary address but uses the
string version of them. So a complete stack is for example:
stack=log2:NFLOG,base1:BASE,ifi1:IFINDEX,ip2str1:IP2STR,mac2str1:HWHDR,json1:JSON
If boolean_label is set to 1, then the numeric_label put on packet
by the input plugin is coding the decision on packet. If 0, then
packet has been blocked and if non null it has been accepted.

Graphite is a web application which provide real-time visualization
and storage of numeric time-series data. This patch adds a module
named GRAPHITE which sends NFACCT accounting data to a graphite
server.

The flags retrieved from `pkg-config --cflags ...` are generally only
preprocessor flags (mostly -I to point to the directories), since
anything else would inconvenience downstream users.

Fixes this error:
make[3]: Entering directory "/home/jengelh/code/ulogd2/output"
CC ulogd_output_XML.lo
ulogd_output_XML.c:31:49: fatal error:
libnetfilter_acct/libnetfilter_acct.h: No such file or directory
(Note that pkgconfig-provided cflags are actually cppflags, so
I add ${LIBNETFILTER_ACCT_CFLAGS} to AM_CPPFLAGS.)

This patch extends XML plugin to support NFACCT. You can use
the following line in ulogd.conf to test it:
stack=acct1:NFACCT,xml1:XML

This fixes the following problem while running `autoreconf -fi`
`pkglibexecdir' is not a legitimate directory for `LTLIBRARIES'
variable `ulogd_filter_PRINTPKT_la_SOURCES' is defined but no program or
library has `ulogd_filter_PRINTPKT_la' as canonical name (possible typo)

This patch adds GPRINT which is a generalization of OPRINT.
It display the set of key-values separated by commas. This is
the generic print that you can attach to whatever kind of
input plugin.

The variable contains global libraries linked into every possible

We must not override CFLAGS, because that will break when the user
overrides CFLAGS again at make time (which he is entitled to). So,
name our CFLAGS regular_CFLAGS, and also include that across all
Makefiles so that they are actually uesd for all the code.

This patch removes the IPFIX from the Makefile. Thus, we keep
it in the tree in the hope that we'll have time to finish it
in the future but don't compile it. This confuses users since
they think that it works.

The modules are pretty much bound to ulogd, and it does not seem
to make sense to specially version these.

libdbi implements a database-independent abstraction layer in C, similar to
the DBI/DBD layer in Perl.
This module brings support for all database types supported by libdbi.

a separate PRINTPKT plugin. This reduces code duplication, and also
makes the SYSLOG and LOGEMU plugins more general. (Philip Craig)
