* crypto: algapi - make unregistration functions return voidEric Biggers2019-12-201-22/+12
| | | | | | | | | | | | | | | | | | Some of the algorithm unregistration functions return -ENOENT when asked to unregister a non-registered algorithm, while others always return 0 or always return void. But no users check the return value, except for two of the bulk unregistration functions which print a message on error but still always return 0 to their caller, and crypto_del_alg() which calls crypto_unregister_instance() which always returns 0. Since unregistering a non-registered algorithm is always a kernel bug but there isn't anything callers should do to handle this situation at runtime, let's simplify things by making all the unregistration functions return void, and moving the error message into crypto_unregister_alg() and upgrading it to a WARN().

* crypto: skcipher - remove the "blkcipher" algorithm typeEric Biggers2019-11-013-28/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: doc - improve the skcipher API example codeEric Biggers2019-06-131-99/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the skcipher API example, changing it to encrypt a buffer with AES-256-XTS. This addresses various problems with the previous example: - It requests a specific driver "cbc-aes-aesni", which is unusual. Normally users ask for "cbc(aes)", not a specific driver. - It encrypts only a single AES block. For the reader, that doesn't clearly distinguish the "skcipher" API from the "cipher" API. - Showing how to encrypt something with bare CBC is arguably a poor choice of example, as it doesn't follow modern crypto trends. Now, usually authenticated encryption is recommended, in which case the user would use the AEAD API, not skcipher. Disk encryption is still a legitimate use for skcipher, but for that usually XTS is recommended. - Many other bugs and poor coding practices, such as not setting CRYPTO_TFM_REQ_MAY_SLEEP, unnecessarily allocating a heap buffer for the IV, unnecessary NULL checks, using a pointless wrapper struct, and forgetting to set an error code in one case.

* crypto: shash - remove shash_desc::flagsEric Biggers2019-04-251-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The flags field in 'struct shash_desc' never actually does anything. The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP. However, no shash algorithm ever sleeps, making this flag a no-op. With this being the case, inevitably some users who can't sleep wrongly pass MAY_SLEEP. These would all need to be fixed if any shash algorithm actually started sleeping. For example, the shash_ahash_*() functions, which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP from the ahash API to the shash API. However, the shash functions are called under kmap_atomic(), so actually they're assumed to never sleep. Even if it turns out that some users do need preemption points while hashing large buffers, we could easily provide a helper function crypto_shash_update_large() which divides the data into smaller chunks and calls crypto_shash_update() and cond_resched() for each chunk. It's not necessary to have a flag in 'struct shash_desc', nor is it necessary to make individual shash algorithms aware of this at all. Therefore, remove shash_desc::flags, and document that the crypto_shash_*() functions can be called from any context.

No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG. Just hardcode "<default>" or "<none>" in those cases. - The 'skcipher_givcrypt_request' structure, which is never used.

| * KEYS: Keyring asymmetric key restrict method with chainingMat Martineau2017-04-041-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a restrict_link_by_key_or_keyring_chain link restriction that searches for signing keys in the destination keyring in addition to the signing key or keyring designated when the destination keyring was created. Userspace enables this behavior by including the "chain" option in the keyring restriction: keyctl(KEYCTL_RESTRICT_KEYRING, keyring, "asymmetric", "key_or_keyring:<signing key>:chain"); Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>
| * KEYS: Restrict asymmetric key linkage using a specific keychainMat Martineau2017-04-041-0/+11
| | | | | | | | | | | | | | | | Adds restrict_link_by_signature_keyring(), which uses the restrict_key member of the provided destination_keyring data structure as the key or keyring to search for signing keys. Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>
