Jan Stancek d3392f41f6 crypto: nx - respect sg limit bounds when building sg lists for SHA ... Commit 000851119e changed sha256/512 update functions to pass more data to nx_build_sg_list(), which ends with sg list overflows and usually with update functions failing for data larger than max_sg_len * NX_PAGE_SIZE. This happens because: - both "total" and "to_process" are updated, which leads to "to_process" getting overflowed for some data lengths For example: In first iteration "total" is 50, and let's assume "to_process" is 30 due to sg limits. At the end of first iteration "total" is set to 20. At start of 2nd iteration "to_process" overflows on: to_process = total - to_process; - "in_sg" is not reset to nx_ctx->in_sg after each iteration - nx_build_sg_list() is hitting overflow because the amount of data passed to it would require more than sgmax elements - as consequence of previous item, data stored in overflowed sg list may no longer be aligned to SHA*_BLOCK_SIZE This patch changes sha256/512 update functions so that "to_process" respects sg limits and never tries to pass more data to nx_build_sg_list() to avoid overflows. "to_process" is calculated as minimum of "total" and sg limits at start of every iteration.
