crypto: api - Replace kernel.h with the necessary inclusions

2021-12-17T05:59:48+00:00

When kernel.h is used in the headers it adds a lot into dependency hell, especially when there are circular dependencies are involved. Replace kernel.h inclusion with the list of what is really being used. Signed-off-by: Andy Shevchenko Signed-off-by: Herbert Xu

Fix some spelling mistakes in comments: cipherntext ==> ciphertext syncronise ==> synchronise feeded ==> fed Signed-off-by: Zhen Lei Signed-off-by: Herbert Xu

crypto: api - check for ERR pointers in crypto_destroy_tfm()

2021-03-12T13:04:01+00:00

Given that crypto_alloc_tfm() may return ERR pointers, and to avoid crashes on obscure error paths where such pointers are presented to crypto_destroy_tfm() (such as [0]), add an ERR_PTR check there before dereferencing the second argument as a struct crypto_tfm pointer.

mm, treewide: rename kzfree() to kfree_sensitive()

2020-08-07T18:33:22+00:00

As said by Linus: A symmetric naming is only helpful if it implies symmetries in use. Otherwise it's actively misleading. In "kzalloc()", the z is meaningful and an important part of what the caller wants. In "kzfree()", the z is actively detrimental, because maybe in the future we really _might_ want to use that "memfill(0xdeadbeef)" or something. The "zero" part of the interface isn't even _relevant_. The main reason that kzfree() exists is to clear sensitive information that should not be leaked to other future users of the same memory objects. Rename kzfree() to kfree_sensitive() to follow the example of the recently added kvfree_sensitive() and make the intention of the API more explicit. In addition, memzero_explicit() is used to clear the memory to make sure that it won't get optimized away by the compiler. The renaming is done by using the command sequence: git grep -w --name-only kzfree |\ xargs sed -i 's/kzfree/kfree_sensitive/' followed by some editing of the kfree_sensitive() kerneldoc and adding a kzfree backward compatibility macro in slab.h.

crypto: aead - move crypto_aead_maxauthsize() to

2019-12-11T08:37:00+00:00

Move crypto_aead_maxauthsize() to so that it's available to users of the API, not just AEAD implementations. This will be used by the self-tests. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: aead - un-inline encrypt and decrypt functions

2019-06-13T06:31:40+00:00

crypto_aead_encrypt() and crypto_aead_decrypt() have grown to be more than a single indirect function call. They now also check whether a key has been set, the decryption side checks whether the input is at least as long as the authentication tag length, and with CONFIG_CRYPTO_STATS=y they also update the crypto statistics. That can add up to a lot of bloat at every call site. Moreover, these always involve a function call anyway, which greatly limits the benefits of inlining. So change them to be non-inline.
