Enable and specify the path to the threshold-file in the suricata.yaml,
otherwise the programm is trying to read it from a build-in default
location and prints the following error message:
Error opening file: "/etc/suricata//threshold.config": No such file or directory

Now all oinkmaster related config files and suricata
related yaml files in "/var/ipfire/suricata/" will be
included into the backups.
Also the entire ruleset is part of the backup, so after a
backup has been restored, the IDS can be used in the same way
as before.
Fixes#11835.

Create this file on first execution of the script if it does not exist yet.
This will allow suricata to imediately be started. Otherwise the ruleset has
to be downloaded and configured before this file has been created and suricata
could be launched.
Fixes#11833.

This function checks if all files located in /etc/suricata/rules are
writable by the effective user and group (nobody:nobody) and if not
calls suricatactl to fix it.

This command is used to set the ownership and permissions
back to nobody:nobdoy which is used by the WUI to write the

Remove a lot of stuff and options which are deactivated during compiling,
unsupported by the plattform or not used in IPFire.
Add an advice to the full documented suricata-example.yaml file which also
is shipped by IPFire.
More work needs to be done.

This generic function can be used to create any kind of emtpy files -
it just requires the full path and filename to work.
If the specified file exists at calltime, the function will abort
to prevent from overwriting existing files and content.

Now the enabled or disabled sids are stored in a single
hash instead of two arrays, which easily can be modified.
When saving the ruleset, the new read_enabled_disabled_sids() function
will be used to read-in the current (old) saved enabled or disabled sids
and add them to the new hash structure.
After adding or modifiying sids to the hash, the entries will be written
to the corresponding files.

This function is used to read-in the files for enabled or disabled sid
files and stores the sid and their state into a temporary hash which will

This commit adds the required backend code to allow switching
between IDS and IPS mode of suricata.
Technically the behaviour of suricata is specified by the rules -
each of them can contain the action "alert" or "drop" (There are
more actions supported but these two are currently the important one)
When running in IDS mode, the ruleset does not need to be touched,
because the default action is "alert". When switching to IPS mode,
the CGI writes a single line to "oinkmaster-modify-sids.conf" which
is included by oinkmaster and modify the action for each single rule
from alert to drop.
