Leonidas S. Barbosa f129430dd8 crypto: nx - Fixing the limit number of bytes to be processed ... The previous limits were estimated locally in a single step basead on bound values, however it was not correct since when given certain scatterlist the function nx_build_sg_lists was consuming more sg entries than allocated causing a memory corruption and crashes. e.g.: in the worst case we could have one sg entry for a single byte. This patch fixes it modifying the logic of the bound limit moving it to nx_sg_build_lists and set a correct sg_max limit, adding a trim function to ensure the bound in sg_list. Also fixing nx_build_sg_list NULL and untreated return in case of overflow. Signed-off-by: Leonidas S.
