Rules Affected
ET open no
ET pro no
-S /dev/null yes
--disable-detection no
at least one rule with file.data as fast_pattern no
ruleset w/o file.data yes
ruleset with file.data, but none are fast_pattern yes

For file.data rules it is irrelevant if they specify alert smb, alert tcp, alert http, etc. As long as the there are rules that have file.data as fast pattern there is no issue.
