crypto: lrw - Fix out-of bounds access on counter overflow

2019-02-11T17:53:22Z

commit fbe1a850b3b1522e9fc22319ccbbcd2ab05328d2 upstream. When the LRW block counter overflows, the current implementation returns 128 as the index to the precomputed multiplication table, which has 128 entries. This patch fixes it to return the correct value (127).

crypto: include crypto- module prefix in template

2015-02-04T10:57:49Z

commit 4943ba16bbc2db05115707b3ff7b4874e9e3c560 upstream. This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause Signed-off-by: Kees Cook Acked-by: Mathias Krause Signed-off-by: Herbert Xu [ luis: backported to 3.16: dropped changes to: - crypto/mcryptd.c ] Signed-off-by: Luis Henriques

crypto: lrw - add interface for parallelized cipher implementions

2011-11-09T03:50:31Z

Export gf128mul table initialization routines and add lrw_crypt() function that can be used by cipher implementations that can benefit from parallelized cipher operations. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: lrw - split gf128mul table initialization from setkey

Split gf128mul initialization from setkey so that it can be used outside lrw-module. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: lrw - use blocksize constant

LRW has fixed blocksize of 16. Define LRW_BLOCK_SIZE and use in place of crypto_cipher_blocksize(). Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: lrw - fix memleak

LRW module leaks child cipher memory when init_tfm() fails because of child block size not being 16. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: lrw - Fix big endian support

2009-02-17T12:00:11Z

It turns out that LRW has never worked properly on big endian. This was never discussed because nobody actually used it that way. In fact, it was only discovered when Geert Uytterhoeven loaded it through tcrypt which failed the test on it. The fix is straightforward, on big endian the to find the nth bit we should be grouping them by words instead of bytes. So setbit128_bbe should xor with 128 - BITS_PER_LONG instead of 128 - BITS_PER_BYTE == 0x78. Tested-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

[CRYPTO] templates: Pass type/mask when creating instances

2007-05-02T04:38:31Z

This patch passes the type/mask along when constructing instances of templates. This is in preparation for templates that may support multiple types of instances depending on what is requested. For example, the planned software async crypto driver will use this construct. For the moment this allows us to check whether the instance constructed is of the correct type and avoid returning success if the type does not match. Signed-off-by: Herbert Xu
