Subject: ids-functions.pl: Check if the generated stored rulesfile of a provider
X-Git-Tag: v2.27-core164~210^2~21
X-Git-Url: http://git.ipfire.org/?p=ipfire-2.x.git;a=commitdiff_plain;h=577e3304953c708bce7f6c067bf34c3f585d3a0f

ids-functions.pl: Check if the generated stored rulesfile of a provider
exists before returning the filename.

This will prevent from using and processing non existing files.
