[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode Main module, this implements the Liskov Rivest Wagner block cipher mode in the new blockcipher API. The implementation is based on ecb.c. The LRW-32-AES specification I used can be found at: http://grouper.ieee.org/groups/1619/email/pdf00017.pdf It implements the optimization specified as optional in the specification, and in addition it uses optimized multiplication routines from gf128mul.c. Since gf128mul.[ch] is not tested on bigendian, this cipher mode may currently fail badly on bigendian machines.

crypto: lrw - Fix big endian support 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.

crypto: lrw - don't access already-freed walk.iv If the user-provided IV needs to be aligned to the algorithm's alignmask, then skcipher_walk_virt() copies the IV into a new aligned buffer walk.iv. But skcipher_walk_virt() can fail afterwards, and then if the caller unconditionally accesses walk.iv, it's a use-after-free. Fix this in the LRW template by checking the return value of skcipher_walk_virt(). This bug was detected by my patches that improve testmgr to fuzz algorithms against their generic implementation. When the extra self-tests were run on a KASAN-enabled kernel, a KASAN use-after-free splat occured during lrw(aes) testing.

[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode Main module, this implements the Liskov Rivest Wagner block cipher mode in the new blockcipher API. The implementation is based on ecb.c. The LRW-32-AES specification I used can be found at: http://grouper.ieee.org/groups/1619/email/pdf00017.pdf It implements the optimization specified as optional in the specification, and in addition it uses optimized multiplication routines from gf128mul.c. Since gf128mul.[ch] is not tested on bigendian, this cipher mode may currently fail badly on bigendian machines.

[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode Main module, this implements the Liskov Rivest Wagner block cipher mode in the new blockcipher API. The implementation is based on ecb.c. The LRW-32-AES specification I used can be found at: http://grouper.ieee.org/groups/1619/email/pdf00017.pdf It implements the optimization specified as optional in the specification, and in addition it uses optimized multiplication routines from gf128mul.c. Since gf128mul.[ch] is not tested on bigendian, this cipher mode may currently fail badly on bigendian machines.

crypto: lrw - Do not use auxiliary buffer This patch simplifies the LRW template to recompute the LRW tweaks from scratch in the second pass and thus also removes the need to allocate a dynamic buffer using kmalloc().

crypto: lrw - Convert to skcipher This patch converts lrw over to the skcipher interface. It also optimises the implementation to be based on ECB instead of the underlying cipher. For compatibility the existing naming scheme of lrw(aes) is maintained as opposed to the more obvious one of lrw(ecb(aes)). Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode Main module, this implements the Liskov Rivest Wagner block cipher mode in the new blockcipher API. The implementation is based on ecb.c. The LRW-32-AES specification I used can be found at: http://grouper.ieee.org/groups/1619/email/pdf00017.pdf It implements the optimization specified as optional in the specification, and in addition it uses optimized multiplication routines from gf128mul.c. Since gf128mul.[ch] is not tested on bigendian, this cipher mode may currently fail badly on bigendian machines.

crypto: lrw - use correct alignmask Commit c778f96bf347 ("crypto: lrw - Optimize tweak computation") incorrectly reduced the alignmask of LRW instances from '__alignof__(u64) - 1' to '__alignof__(__be32) - 1'. However, xor_tweak() and setkey() assume that the data and key, respectively, are aligned to 'be128', which has u64 alignment. Fix the alignmask to be at least '__alignof__(be128) - 1'.

crypto: run initcalls for generic implementations earlier Use subsys_initcall for registration of all templates and generic algorithm implementations, rather than module_init. Then change cryptomgr to use arch_initcall, to place it before the subsys_initcalls. This is needed so that when both a generic and optimized implementation of an algorithm are built into the kernel (not loadable modules), the generic implementation is registered before the optimized one. Otherwise, the self-tests for the optimized implementation are unable to allocate the generic implementation for the new comparison fuzz tests. Note that on arm, a side effect of this change is that self-tests for generic implementations may run before the unaligned access handler has been installed. So, unaligned accesses will crash the kernel. This is arguably a good thing as it makes it easier to detect that type of bug.
