port is not used and logically makes sense to not be in this struct as this struct is already referenced by DetectPort itself as a part of SigGroupHead.
Present scenario ---------------- Currently, as a part of setting signature count per SGH, a max_idx is passed which could be as high as the highest signature number (internal ID). Issue ----- Not every SGH needs to evaluate all the signatures while setting the signature count or while creating the match_array. In a nonideal scenario, when say, there are 2 SGHs and one SGH has 2 signatures and the other one has 60k, given the current scheme of evaluating max_idx, the max_idx will be set to 60k, and this shall later be passed on to SigGroupHeadSetSigCnt or SigGroupHeadBuildMatchArra which shall traverse over all the 60k sigs for either SGHs. Other info ---------- This is a very fast operation as the internal arithmetic is done bitwise. Patch ----- The functions SigGroupHeadSetSigCnt and SigGroupHeadBuildMatchArray can be optimized by storing the max signature id (internal) per SGH (which also seemed to be the initial intention as per fn comments). As a result of this, the sig_array is only walked up until the max sig id of that respective SGH.
