crypto: skcipher - add the ability to abort a skcipher walk

2019-09-09T07:35:38Z

After starting a skcipher walk, the only way to ensure that all resources it has tied up are released is to complete it. In some cases, it will be useful to be able to abort a walk cleanly after it has started, so add this ability to the skcipher walk API. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: des - split off DES library from generic DES cipher driver

2019-08-22T04:57:33Z

Another one for the cipher museum: split off DES core processing into a separate module so other drivers (mostly for crypto accelerators) can reuse the code without pulling in the generic DES cipher itself. This will also permit the cipher interface to be made private to the crypto API itself once we move the only user in the kernel (CIFS) to this library interface.

crypto: des/3des_ede - add new helpers to verify keys

2019-08-22T04:39:37Z

The recently added helper routine to perform key strength validation of triple DES keys is slightly inadequate, since it comes in two versions, neither of which are highly useful for anything other than skciphers (and many drivers still use the older blkcipher interfaces). So let's add a new helper and, considering that this is a helper function that is only intended to be used by crypto code itself, put it in a new des.h header under crypto/internal. While at it, implement a similar helper for single DES, so that we can start replacing the pattern of calling des_ekey() into a temp buffer that occurs in many drivers in drivers/crypto.

crypto: user - fix potential warnings in cryptouser.h

2019-08-02T04:44:31Z

Function definitions in headers are usually marked as 'static inline'. Since 'inline' is missing for crypto_reportstat(), if it were not referenced from a .c file that includes this header, it would produce a warning. Also, 'struct crypto_user_alg' is not declared in this header. I included instead of adding the forward declaration as suggested [1]. Detected by compile-testing this header as a standalone unit: ./include/crypto/internal/cryptouser.h:6:44: warning: ‘struct crypto_user_alg’ declared inside parameter list will not be visible outside of this definition or declaration struct crypto_alg *crypto_alg_match(struct crypto_user_alg *p, int exact); ^~~~~~~~~~~~~~~ ./include/crypto/internal/cryptouser.h:11:12: warning: ‘crypto_reportstat’ defined but not used [-Wunused-function] static int crypto_reportstat(struct sk_buff *in_skb, struct nlmsghdr *in_nlh, struct nlattr **attrs) ^~~~~~~~~~~~~~~~~ [1] https://lkml.org/lkml/2019/6/13/1121 Signed-off-by: Masahiro Yamada Signed-off-by: Herbert Xu

crypto: user - make NETLINK_CRYPTO work inside netns

2019-07-26T12:08:02Z

Currently, NETLINK_CRYPTO works only in the init network namespace. It doesn't make much sense to cut it out of the other network namespaces, so do the minor plumbing work necessary to make it work in any network namespace. Code inspired by net/core/sock_diag.c. Tested using kcapi-dgst from libkcapi [1]: Before: # unshare -n kcapi-dgst -c sha256 Signed-off-by: Herbert Xu

crypto: skcipher - make chunksize and walksize accessors internal

2019-06-13T06:31:40Z

The 'chunksize' and 'walksize' properties of skcipher algorithms are implementation details that users of the skcipher API should not be looking at. So move their accessor functions from to . Signed-off-by: Eric Biggers Acked-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: simd,testmgr - introduce crypto_simd_usable()

2019-03-22T12:57:27Z

So that the no-SIMD fallback code can be tested by the crypto self-tests, add a macro crypto_simd_usable() which wraps may_use_simd(), but also returns false if the crypto self-tests have set a per-CPU bool to disable SIMD in crypto code on the current CPU.
