Detailed Description

Function Documentation

◆ CleanupFPAnalyzer()

void CleanupFPAnalyzer ( void  )

Definition at line 392 of file detect-engine-analyzer.c.

◆ CleanupRuleAnalyzer()

void CleanupRuleAnalyzer ( void  )

Definition at line 416 of file detect-engine-analyzer.c.

◆ EngineAnalysisFP()

◆ EngineAnalysisRules()

void EngineAnalysisRules ( const DetectEngineCtx de_ctx,
const Signature s,
const char *  line 
)

Prints analysis of loaded rules.

   Warns if potential rule issues are detected. For example,
   warns if a rule uses a construct that may perform poorly,
   e.g. pcre without content or with http_method content only;
   warns if a rule uses a construct that may not be consistent with intent,
   e.g. client side ports only, http and content without any http_* modifiers, etc.
Parameters
sPointer to the signature.
