-Subject: [PATCH] Avoid some undefined pointer arithmetic
-
-A common idiom in the codebase is:
-
-if (p + len > limit)
-{
-    return; /* Too long */
-}
-
-Where "p" points to some malloc'd data of SIZE bytes and
-limit == p + SIZE
-
-"len" here could be from some externally supplied data (e.g. from a TLS
-message).
-
-The rules of C pointer arithmetic are such that "p + len" is only well
-defined where len <= SIZE. Therefore the above idiom is actually
-undefined behaviour.
-
-For example this could cause problems if some malloc implementation
-provides an address for "p" such that "p + len" actually overflows for
-values of len that are too big and therefore p + len < limit!
-
-Issue reported by Guido Vranken.
