This patch fixes a NULL dereference to the timestamp structure when
hashtable_add() fails, for example, because the hashtable is full.

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

This patch cleans up the current key assignation by introducing a
set of functions ukey_* to set the key value as Eric Leblond and
we discussed during the latest Netfilter Workshop. This patch is
based on an idea from Holger Eitzenberger.

Fixes compilation of NFLOG and NFCT plugin when libnetfilter libraries
are installed under a non standard prefix. Include path and libs path
for libnetfilter_conntrack and libnetfilter_log were not correctly set even
if pkg-config found them.

This patch fixes some messages in the NFCT and NFLOG input
plugin (end of line before quote). It also fixes indenting by
suppressing some spaces on empty line and replacing spaces by tab.

This patch fixes NFCT when hash_enable is 0. Limitation of treatment to
NFCT_DESTROY message type causes usage of the hashtable function and
hence a crash because it is not initiated.

This patch cleans up the key building by breaking lines at 80 columns and
it fixes the IPv6 support (use of a pointer after free) by introducing a new

This patch improves the overrun handling. The logic behind this patch
consists of two steps:
1) duplicate the netlink buffer size if the size does not goes after the
upper boundary.
2) scheduling a resynchronization (in two seconds) with the kernel conntrack
table if we hit ENOBUFS. During the resynchronization, the NFCT plugin dumps
the current table and purges the objects that do not exist anymore.
This patch also introduces two new clauses, the netlink_socket_buffer_size
and netlink_socket_buffer_maxsize that set the size of the netlink socket
buffer.

This patch introduces a generic hashtable to store the nf_conntrack objects.
The objects are identified by the original and reply tuples instead of the
conntrack ID which is not dumped in the event message of linux kernel < 2.6.25.
This patch also fixes the NFCT_MSG_* by NFCT_T_* which is the appropriate
message type tag.

- event mask is now configurable though the event_mask configuration variable
- event type is now stored in the ct.event output key. This can be used to
display the information or to use it to implement some tracking algorithm in

original patch by Christian Hentschel, amended like:
1) the hash table has to be per-instance, since [at least in the future]
we can have nfnetlink messages routed from other machines over the
network, thus every NFCT instance has to have it's own hash table.
2) Whether or not to use a preallocated table is now a configuration
value, as is the number of buckets and max_entries
3) configure_nfct was not used in the struct ulogd_plugin.configure
4) don't put the hashtable buckets in BSS, but rather allocate them
dynamically
5) allocate all ct_timestamps (in the preallocated case) at once, rather
than malloc()ing each on its own.
6) use official IPFIX fields for flow start and flow end instead of
private numbers
7) use llist instead of list (linuxlist.h adds an additional 'l')
8) add lots of TODO items
9) add IPFIX_NF_conntrack_id to header file
