crypto: ablkcipher - remove deprecated and unused ablkcipher support

2019-11-17T01:02:49Z

Now that all users of the deprecated ablkcipher interface have been moved to the skcipher interface, ablkcipher is no longer used and can be removed. Reviewed-by: Eric Biggers Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: skcipher - remove the "blkcipher" algorithm type

2019-11-01T05:38:32Z

Now that all "blkcipher" algorithms have been converted to "skcipher", remove the blkcipher algorithm type. The skcipher (symmetric key cipher) algorithm type was introduced a few years ago to replace both blkcipher and ablkcipher (synchronous and asynchronous block cipher). The advantages of skcipher include: - A much less confusing name, since none of these algorithm types have ever actually been for raw block ciphers, but rather for all length-preserving encryption modes including block cipher modes of operation, stream ciphers, and other length-preserving modes. - It unified blkcipher and ablkcipher into a single algorithm type which supports both synchronous and asynchronous implementations. Note, blkcipher already operated only on scatterlists, so the fact that skcipher does too isn't a regression in functionality. - Better type safety by using struct skcipher_alg, struct crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc. - It sometimes simplifies the implementations of algorithms. Also, the blkcipher API was no longer being tested. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: api - Remove redundant #ifdef in crypto_yield()

2019-08-02T04:45:13Z

While looking at CONFIG_PREEMPT dependencies treewide the #ifdef in crypto_yield() matched. CONFIG_PREEMPT and CONFIG_PREEMPT_VOLUNTARY are mutually exclusive so the extra !CONFIG_PREEMPT conditional is redundant. cond_resched() has only an effect when CONFIG_PREEMPT_VOLUNTARY is set, otherwise it's a stub which the compiler optimizes out. Remove the whole conditional. No functional change. Signed-off-by: Thomas Gleixner Cc: linux-crypto@vger.kernel.org Cc: Herbert Xu Cc: "David S. Miller" Signed-off-by: Herbert Xu

crypto: algapi - remove crypto_alloc_instance()

2019-01-11T06:16:58Z

Now that all "blkcipher" templates have been converted to "skcipher", crypto_alloc_instance() is no longer used. And it's not useful any longer as it creates an old-style weakly typed instance rather than a new-style strongly typed instance. So remove it, and now that the name is freed up rename crypto_alloc_instance2() to crypto_alloc_instance(). Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: api - Introduce notifier for new crypto algorithms

2018-09-04T03:37:04Z

Introduce a facility that can be used to receive a notification callback when a new algorithm becomes available. This can be used by existing crypto registrations to trigger a switch from a software-only algorithm to a hardware-accelerated version. A new CRYPTO_MSG_ALG_LOADED state is introduced to the existing crypto notification chain, and the register/unregister functions are exported so they can be called by subsystems outside of crypto.

crypto: api - Introduce generic max blocksize and alignmask

2018-09-04T03:35:04Z

In the quest to remove all stack VLA usage from the kernel[1], this exposes a new general upper bound on crypto blocksize and alignmask (higher than for the existing cipher limits) for VLA removal, and introduces new checks. At present, the highest cra_alignmask in the kernel is 63. The highest cra_blocksize is 144 (SHA3_224_BLOCK_SIZE, 18 8-byte words). For the new blocksize limit, I went with 160 (20 8-byte words).
