This commit makes the detection engine thread context available for transforms to use. The Lua transform requires this value. Issue: 2290
Issue: 2290 This commit extends the hash table logic with an alternate free function that provides the detection engine context. Users that wish to use the next functionality must use the HashListTableInitWithCtx function when initializing the hash table. Using this interface will result in the hash table "free with context" function (new) being used instead.
Issue: 2290 Defer freeing the keyword hash table until the engine context has been freed. This eliminates a double-free from occurring. For the unittests ONLY, clear the keyword_hash to prevent a double free attempt.
So transforms can access them through DetectEngineThreadCtx
git grep -A 1 -w InspectionBufferSetup shows numbers cases of the pattern:
- InspectionBufferSetup
- InspectionBufferApplyTransforms
Refactor the implementations of those functions into
InspectionBufferSetupAndApplyTransforms to reduce function call count.
