'iptables 1.8.3' => 'collectd' needs updated lib

Hi,

during testing of 'iptables 1.8.3' - see
https://patchwork.ipfire.org/patch/2401/ I found that the graphs for
"firewallhits" in "Network (other)" stayed emtpy with "-nan Bps".

During restart 'makegraphs' complained about a missing lib for 'iptables':

root(a)ipfire: /var # /etc/init.d/collectd restart
Stopping Collection daemon...                                   [  OK  ]
Mounting RRD ramdisk...                                         [  OK  ]
Starting Collection daemon...
lt_dlopen ("/usr/lib/collectd/iptables.so") failed: file not found. The
most common cause for this problem are missing dependencies. Use ldd(1)
to check the dependencies of the plugin / shared object.
Unable to load plugin iptables.                                 [  OK  ]

'ldd' showed 'not found', because during updating 'iptables' the
'libip4tc' and 'libip6tc'-symlinks were changed, but
'/usr/lib/collectd/iptables.so' wasn't updated:

root(a)ipfire: /usr/lib/collectd # ldd /usr/lib/collectd/iptables.so
        linux-gate.so.1 (0xb7f42000)
        libiptc.so.0 => /lib/libiptc.so.0 (0xb7f2b000)
        libip4tc.so.0 => not found
        libip6tc.so.0 => not found
        libc.so.6 => /lib/libc.so.6 (0xb7d61000)
        libip4tc.so.2 => /lib/libip4tc.so.2 (0xb7d58000)
        libip6tc.so.2 => /lib/libip6tc.so.2 (0xb7d4f000)
        /lib/ld-linux.so.2 (0xb7f44000)

After updating '/usr/lib/collectd/iptables.so' to the current build it
didn't complain anymore:

root(a)ipfire: /usr/lib/collectd # ldd iptables.so
        linux-gate.so.1 (0xb7f8a000)
        libiptc.so.0 => /lib/libiptc.so.0 (0xb7f72000)
        libip4tc.so.2 => /lib/libip4tc.so.2 (0xb7f69000)
        libip6tc.so.2 => /lib/libip6tc.so.2 (0xb7f60000)
        libc.so.6 => /lib/libc.so.6 (0xb7d96000)
        /lib/ld-linux.so.2 (0xb7f8c000)

'makegraphs' restarted without errors and "firewallhits graph" are
showing numbers again. So far, so good.

But: how do we ship this update for 'collectd' the best way?

Should we update ALL libs for 'collectd'?

I checked the other libs, and besides 'iptables.so', 'ldd' showed no
more 'not found'-errors.

Any hints?

Best,
Matthias
