Subject: conntrackd: cthelper: Free pktb after use
According to valgrind, this currently leaks ~512B to 2kB for each
packet sent to the userspace helper.

From 1ba5e76a368aeb9fe17d3b691df4faa0dadc4523 Mon Sep 17 00:00:00 2001
From: Kevin Cernekee <cernekee@chromium.org>
Date: Thu, 26 Jan 2017 16:44:24 -0800
Subject: conntrackd: cthelper: Don't leak nat_tuple
nfexp_set_attr() copies |nat_tuple| rather than taking ownership, so
it should be freed at the end of the loop. Some of the other helpers
(like rpc.c) do this, but it is missing here.

%description
With conntrack-tools you can setup a High Availability cluster and
synchronize conntrack state between multiple firewalls.
The conntrack-tools package contains two programs:
- conntrack: the command line interface to interact with the connection
tracking system.
- conntrackd: the connection tracking userspace daemon that can be used to
deploy highly available GNU/Linux firewalls and collect
statistics of the firewall use.
conntrack is used to search, list, inspect and maintain the netfilter
connection tracking subsystem of the Linux kernel.
Using conntrack, you can dump a list of all (or a filtered selection of)
currently tracked connections, delete connections from the state table,
and even add new ones.
In addition, you can also monitor connection tracking events, e.g.
show an event message (one line) per newly established connection.

# See also: http://conntrack-tools.netfilter.org/support.html
#
# There are 3 different modes of running conntrackd: "alarm", "notrack" and "ftfw"
#
# The default package ships with a FTFW configuration, see /usr/share/doc/conntrackd*
# for example configurations for other modes.
#
# Synchronizer settings
#
Sync {
Mode FTFW {
#
# Size of the resend queue (in objects). This is the maximum
# number of objects that can be stored waiting to be confirmed
# via acknoledgment. If you keep this value low, the daemon
# will have less chances to recover state-changes under message
# omission. On the other hand, if you keep this value high,
# the daemon will consume more memory to store dead objects.
# Default is 131072 objects.
#
# ResendQueueSize 131072
#
# This parameter allows you to set an initial fixed timeout
# for the committed entries when this node goes from backup
# to primary. This mechanism provides a way to purge entries
# that were not recovered appropriately after the specified
# fixed timeout. If you set a low value, TCP entries in
# Established states with no traffic may hang. For example,
# an SSH connection without KeepAlive enabled. If not set,
# the daemon uses an approximate timeout value calculation
# mechanism. By default, this option is not set.
#
# CommitTimeout 180
#
# If the firewall replica goes from primary to backup,
# the conntrackd -t command is invoked in the script.
# This command schedules a flush of the table in N seconds.
# This is useful to purge the connection tracking table of
# zombie entries and avoid clashes with old entries if you
# trigger several consecutive hand-overs. Default is 60 seconds.
#
# PurgeTimeout 60
# Set the acknowledgement window size. If you decrease this
# value, the number of acknowlegdments increases. More
# acknowledgments means more overhead as conntrackd has to
# handle more control messages. On the other hand, if you
# increase this value, the resend queue gets more populated.
# This results in more overhead in the queue releasing.
# The following value is based on some practical experiments
# measuring the cycles spent by the acknowledgment handling
# with oprofile. If not set, default window size is 300.
#
# ACKWindowSize 300
#
# This clause allows you to disable the external cache. Thus,
# the state entries are directly injected into the kernel
# conntrack table. As a result, you save memory in user-space
# but you consume slots in the kernel conntrack table for
# backup state entries. Moreover, disabling the external cache
# means more CPU consumption. You need a Linux kernel
# >= 2.6.29 to use this feature. By default, this clause is
# set off. If you are installing conntrackd for first time,
# please read the user manual and I encourage you to consider
# using the fail-over scripts instead of enabling this option!

# Netlink event socket buffer size. If you do not specify this clause,
# the default buffer size value in /proc/net/core/rmem_default is
# used. This default value is usually around 100 Kbytes which is
# fairly small for busy firewalls. This leads to event message dropping
# and high CPU consumption. This example configuration file sets the
# size to 2 MBytes to avoid this sort of problems.
#
NetlinkBufferSize 2097152
#
# The daemon doubles the size of the netlink event socket buffer size
# if it detects netlink event message dropping. This clause sets the
# maximum buffer size growth that can be reached. This example file
# sets the size to 8 MBytes.
#
NetlinkBufferSizeMaxGrowth 8388608
#
# If the daemon detects that Netlink is dropping state-change events,
# it automatically schedules a resynchronization against the Kernel
# after 30 seconds (default value). Resynchronizations are expensive
# in terms of CPU consumption since the daemon has to get the full
# kernel state-table and purge state-entries that do not exist anymore.
# Be careful of setting a very small value here. You have the following
# choices: On (enabled, use default 30 seconds value), Off (disabled)
# or Value (in seconds, to set a specific amount of time). If not
# specified, the daemon assumes that this option is enabled.
#
# NetlinkOverrunResync On
#
# If you want reliable event reporting over Netlink, set on this
# option. If you set on this clause, it is a good idea to set off
# NetlinkOverrunResync. This option is off by default and you need
# a Linux kernel >= 2.6.31.
#
# NetlinkEventsReliable Off
#
# By default, the daemon receives state updates following an
# event-driven model. You can modify this behaviour by switching to
# polling mode with the PollSecs clause. This clause tells conntrackd
# to dump the states in the kernel every N seconds. With regards to
# synchronization mode, the polling mode can only guarantee that
# long-lifetime states are recovered. The main advantage of this method
# is the reduction in the state replication at the cost of reducing the
# chances of recovering connections.
#
# PollSecs 15
#
# The daemon prioritizes the handling of state-change events coming
# from the core. With this clause, you can set the maximum number of
# state-change events (those coming from kernel-space) that the daemon
# will handle after which it will handle other events coming from the
# network or userspace. A low value improves interactivity (in terms of
# real-time behaviour) at the cost of extra CPU consumption.
# Default (if not set) is 100.
#
# EventIterationLimit 100
#
# Event filtering: This clause allows you to filter certain traffic,
# There are currently three filter-sets: Protocol, Address and
# State. The filter is attached to an action that can be: Accept or
# Ignore. Thus, you can define the event filtering policy of the
# filter-sets in positive or negative logic depending on your needs.
# You can select if conntrackd filters the event messages from
# user-space or kernel-space. The kernel-space event filtering
# saves some CPU cycles by avoiding the copy of the event message
# from kernel-space to user-space. The kernel-space event filtering
# is prefered, however, you require a Linux kernel >= 2.6.29 to
# filter from kernel-space. If you want to select kernel-space
# event filtering, use the keyword 'Kernelspace' instead of
# 'Userspace'.
