git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull keyring updates from David Howells: "Here's a set of minor keyrings fixes/cleanups that I've collected from various people for the upcoming merge window. A couple of them might, in theory, be visible to userspace: - Make blacklist_vet_description() reject uppercase letters as they don't match the all-lowercase hex string generated for a blacklist search. This may want reconsideration in the future, but, currently, you can't add to the blacklist keyring from userspace and the only source of blacklist keys generates lowercase descriptions. - Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that it wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP into keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag. This isn't currently a problem as the blacklist keyring isn't currently writable by userspace. The rest of the patches are cleanups and I don't think they should have any visible effect" * tag 'keys-misc-20210126' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: watch_queue: rectify kernel-doc for init_watch() certs: Replace K{U,G}IDT_INIT() with GLOBAL_ROOT_{U,G}ID certs: Fix blacklist flag type confusion PKCS#7: Fix missing include certs: Fix blacklisted hexadecimal hash string check certs/blacklist: fix kernel doc interface issue crypto: public_key: Remove redundant header file from public_key.h keys: remove trailing semicolon in macro definition crypto: pkcs7: Use match_string() helper to simplify the code PKCS#7: drop function from kernel-doc pkcs7_validate_trust_one encrypted-keys: Replace HTTP links with HTTPS ones crypto: asymmetric_keys: fix some comments in pkcs7_parser.h KEYS: remove redundant memset security: keys: delete repeated words in comments KEYS: asymmetric: Fix kerneldoc security/keys: use kvfree_sensitive() watch_queue: Drop references to /dev/watch_queue keys: Remove outdated __user annotations security: keys: Fix fall-through warnings for Clang

This could lead to an out-of-bounds access when the passed length is less than the encoded length. Add a check to prevent that.

2021-02-10crypto: serpent - get rid of obsolete tnepres variantArd Biesheuvel5-169/+7
It is not trivial to trace back why exactly the tnepres variant of serpent was added ~17 years ago - Google searches come up mostly empty, but it seems to be related with the 'kerneli' version, which was based on an incorrect interpretation of the serpent spec. In other words, nobody is likely to care anymore today, so let's get rid of it. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2021-02-10crypto: michael_mic - fix broken misalignment handlingArd Biesheuvel1-19/+12
The Michael MIC driver uses the cra_alignmask to ensure that pointers presented to its update and finup/final methods are 32-bit aligned. However, due to the way the shash API works, this is no guarantee that the 32-bit reads occurring in the update method are also aligned, as the size of the buffer presented to update may be of uneven length. For instance, an update() of 3 bytes followed by a misaligned update() of 4 or more bytes will result in a misaligned access using an accessor that is not suitable for this. On most architectures, this does not matter, and so setting the cra_alignmask is pointless. On architectures where this does matter, setting the cra_alignmask does not actually solve the problem. So let's get rid of the cra_alignmask, and use unaligned accessors instead, where appropriate.

2021-01-08crypto: x86/aes-ni-xts - rewrite and drop indirections via glue helperArd Biesheuvel1-1/+0
The AES-NI driver implements XTS via the glue helper, which consumes a struct with sets of function pointers which are invoked on chunks of input data of the appropriate size, as annotated in the struct. Let's get rid of this indirection, so that we can perform direct calls to the assembler helpers. Instead, let's adopt the arm64 strategy, i.e., provide a helper which can consume inputs of any size, provided that the penultimate, full block is passed via the last call if ciphertext stealing needs to be applied. This also allows us to enable the XTS mode for i386.

2021-01-03crypto: blake2b - update file commentEric Biggers1-13/+10
The file comment for blake2b_generic.c makes it sound like it's the reference implementation of BLAKE2b with only minor changes. But it's actually been changed a lot. Update the comment to make this clearer.

2021-01-03crypto: blake2b - sync with blake2s implementationEric Biggers1-178/+48
Sync the BLAKE2b code with the BLAKE2s code as much as possible: - Move a lot of code into new headers <crypto/blake2b.h> and <crypto/internal/blake2b.h>, and adjust it to be like the corresponding BLAKE2s code, i.e. like <crypto/blake2s.h> and <crypto/internal/blake2s.h>. - Rename constants, e.g. BLAKE2B_*_DIGEST_SIZE => BLAKE2B_*_HASH_SIZE. - Use a macro BLAKE2B_ALG() to define the shash_alg structs. - Export blake2b_compress_generic() for use as a fallback. This makes it much easier to add optimized implementations of BLAKE2b, as optimized implementations can use the helper functions crypto_blake2b_{setkey,init,update,final}() and blake2b_compress_generic(). The ARM implementation will use these. But this change is also helpful because it eliminates unnecessary differences between the BLAKE2b and BLAKE2s code, so that the same improvements can easily be made to both. (The two algorithms are basically identical, except for the word size and constants.) It also makes it straightforward to add a library API for BLAKE2b in the future if/when it's needed. This change does make the BLAKE2b code slightly more complicated than it needs to be, as it doesn't actually provide a library API yet. For example, __blake2b_update() doesn't really need to exist yet; it could just be inlined into crypto_blake2b_update(). But I believe this is outweighed by the benefits of keeping the code in sync.

2021-01-03crypto: blake2s - share the "shash" API boilerplate codeEric Biggers1-67/+9
Add helper functions for shash implementations of BLAKE2s to include/crypto/internal/blake2s.h, taking advantage of __blake2s_update() and __blake2s_final() that were added by the previous patch to share more code between the library and shash implementations. crypto_blake2s_setkey() and crypto_blake2s_init() are usable as shash_alg::setkey and shash_alg::init directly, while crypto_blake2s_update() and crypto_blake2s_final() take an extra 'blake2s_compress_t' function pointer parameter. This allows the implementation of the compression function to be overridden, which is the only part that optimized implementations really care about. The new functions are inline functions (similar to those in sha1_base.h, sha256_base.h, and sm3_base.h) because this avoids needing to add a new module blake2s_helpers.ko, they aren't *too* long, and this avoids indirect calls which are expensive these days. Note that they can't go in blake2s_generic.ko, as that would require selecting CRYPTO_BLAKE2S from CRYPTO_BLAKE2S_X86, which would cause a recursive dependency. Finally, use these new helper functions in the x86 implementation of BLAKE2s. (This part should be a separate patch, but unfortunately the x86 implementation used the exact same function names like "crypto_blake2s_update()", so it had to be updated at the same time.)

2021-01-03crypto: blake2s - remove unneeded includesEric Biggers1-2/+0
It doesn't make sense for the generic implementation of BLAKE2s to include <crypto/internal/simd.h> and <linux/jump_label.h>, as these are things that would only be useful in an architecture-specific implementation. Remove these unnecessary includes. Acked-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2021-01-03crypto: blake2s - define shash_alg structs using macrosEric Biggers1-61/+27
The shash_alg structs for the four variants of BLAKE2s are identical except for the algorithm name, driver name, and digest size. So, avoid code duplication by using a macro to define these structs.

2021-01-03crypto: remove cipher routines from public crypto APIArd Biesheuvel19-3/+39
The cipher routines in the crypto API are mostly intended for templates implementing skcipher modes generically in software, and shouldn't be used outside of the crypto subsystem. So move the prototypes and all related definitions to a new header file under include/crypto/internal. Also, let's use the new module namespace feature to move the symbol exports into a new namespace CRYPTO_INTERNAL.
