[TEXTSEARCH]: Fix broken good shift array calculation in Boyer-Moore
The current logic does not calculate correctly the good shift array: Let x be the pattern that is being searched. Let y be the block of data. The good shift array aligns the segment: x[i+1 ... m-1] = y[i+j+1 ... j+m-1] with its rightmost occurrence in x that fulfils x[i] neq y[i+j]. In previous version, the good shift array for the pattern ANPANMAN is: [1, 8, 3, 8, 8, 8, 8, 8] and should be: [1, 8, 3, 6, 6, 6, 6, 6] Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.
