* crypto: api - Use data directly in completion functionHerbert Xu2023-02-1319-139/+124
| | | | | | | This patch does the final flag day conversion of all completion functions which are now all contained in the Crypto API. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | Use the akcipher_request_complete helper instead of calling the completion function directly. In fact the previous code was buggy in that EINPROGRESS was never passed back to the original caller.

| | | | | | | | | | Use the crypto_request_complete helper instead of calling the completion function directly. This patch also removes the voodoo programming previously used for unaligned ahash operations and replaces it with a sub-request. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Use subreq for AEADHerbert Xu2023-02-131-4/+16
| | | | | | | | | | | AEAD reuses the existing request object for its child. This is error-prone and unnecessary. This patch adds a subrequest object just like we do for skcipher and hash. This patch also restores the original completion function as we do for skcipher/hash. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: skcipher - Use scatterwalk (un)map interface for dst and src buffersArd Biesheuvel2023-01-131-18/+4
| | | | | | | | | | | | | | | The skcipher walk API implementation avoids scatterwalk_map() for mapping the source and destination buffers, and invokes kmap_atomic() directly if the buffer in question is not in low memory (which can only happen on 32-bit architectures). This avoids some overhead on 64-bit architectures, and most notably, permits the skcipher code to run with preemption enabled. Now that scatterwalk_map() has been updated to use kmap_local(), none of this is needed, so we can simply use scatterwalk_map/unmap instead.

* crypto: x86/aria - do not use magic number offsets of aria_ctxTaehee Yoo2023-01-061-0/+4
| | | | | | | | | | | | | | | | aria-avx assembly code accesses members of aria_ctx with magic number offset. If the shape of struct aria_ctx is changed carelessly, aria-avx will not work. So, we need to ensure accessing members of aria_ctx with correct offset values, not with magic numbers. It adds ARIA_CTX_enc_key, ARIA_CTX_dec_key, and ARIA_CTX_rounds in the asm-offsets.c So, correct offset definitions will be generated. aria-avx assembly code can access members of aria_ctx safely with these definitions.

* crypto: scatterwalk - use kmap_local() not kmap_atomic()Ard Biesheuvel2022-12-302-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | kmap_atomic() is used to create short-lived mappings of pages that may not be accessible via the kernel direct map. This is only needed on 32-bit architectures that implement CONFIG_HIGHMEM, but it can be used on 64-bit other architectures too, where the returned mapping is simply the kernel direct address of the page. However, kmap_atomic() does not support migration on CONFIG_HIGHMEM configurations, due to the use of per-CPU kmap slots, and so it disables preemption on all architectures, not just the 32-bit ones. This implies that all scatterwalk based crypto routines essentially execute with preemption disabled all the time, which is less than ideal. So let's switch scatterwalk_map/_unmap and the shash/ahash routines to kmap_local() instead, which serves a similar purpose, but without the resulting impact on preemption on architectures that have no need for CONFIG_HIGHMEM.

| * crypto: api - optimize algorithm registration when self-tests disabledEric Biggers2022-11-252-71/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, registering an algorithm with the crypto API always causes a notification to be posted to the "cryptomgr", which then creates a kthread to self-test the algorithm. However, if self-tests are disabled in the kconfig (as is the default option), then this kthread just notifies waiters that the algorithm has been tested, then exits. This causes a significant amount of overhead, especially in the kthread creation and destruction, which is not necessary at all. For example, in a quick test I found that booting a "minimum" x86_64 kernel with all the crypto options enabled (except for the self-tests) takes about 400ms until PID 1 can start. Of that, a full 13ms is spent just doing this pointless dance, involving a kthread being created, run, and destroyed over 200 times. That's over 3% of the entire kernel start time. Fix this by just skipping the creation of the test larval and the posting of the registration notification entirely, when self-tests are disabled.

| * crypto: tcrypt - Use pr_cont to print test resultsAnirudh Venkataramanan2022-11-041-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some test cases, a line break gets inserted between the test banner and the results. For example, with mode=211 this is the output: [...] testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption [...] test 0 (160 bit key, 16 byte blocks): [...] 1 operation in 2373 cycles (16 bytes) --snip-- [...] testing speed of gcm(aes) (generic-gcm-aesni) encryption [...] test 0 (128 bit key, 16 byte blocks): [...] 1 operation in 2338 cycles (16 bytes) Similar behavior is seen in the following cases as well: modprobe tcrypt mode=212 modprobe tcrypt mode=213 modprobe tcrypt mode=221 modprobe tcrypt mode=300 sec=1 modprobe tcrypt mode=400 sec=1 This doesn't happen with mode=215: [...] tcrypt: testing speed of multibuffer rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption [...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2215 cycles (16 bytes) --snip-- [...] tcrypt: testing speed of multibuffer gcm(aes) (generic-gcm-aesni) encryption [...] tcrypt: test 0 (128 bit key, 16 byte blocks): 1 operation in 2191 cycles (16 bytes) This print inconsistency is because printk() is used instead of pr_cont() in a few places. Change these to be pr_cont(). checkpatch warns that pr_cont() shouldn't be used. This can be ignored in this context as tcrypt already uses pr_cont().

| * crypto: af_alg - Support symmetric encryption via keyring keysFrederick Lawler2022-10-281-1/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to leverage keyring to store sensitive keys, and then use those keys for symmetric encryption via the crypto API. Among the key types we wish to support are: user, logon, encrypted, and trusted. User key types are already able to have their data copied to user space, but logon does not support this. Further, trusted and encrypted keys will return their encrypted data back to user space on read, which does not make them ideal for symmetric encryption. To support symmetric encryption for these key types, add a new ALG_SET_KEY_BY_KEY_SERIAL setsockopt() option to the crypto API. This allows users to pass a key_serial_t to the crypto API to perform symmetric encryption. The behavior is the same as ALG_SET_KEY, but the crypto key data is copied in kernel space from a keyring key, which allows for the support of logon, encrypted, and trusted key types. Keyring keys must have the KEY_(POS|USR|GRP|OTH)_SEARCH permission set to leverage this feature. This follows the asymmetric_key type where key lookup calls eventually lead to keyring_search_rcu() without the KEYRING_SEARCH_NO_CHECK_PERM flag set.

| * crypto: tcrypt - fix return value for multiple subtestsRobert Elliott2022-10-211-128/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When a test mode invokes multiple tests (e.g., mode 0 invokes modes 1 through 199, and mode 3 tests three block cipher modes with des), don't keep accumulating the return values with ret += tcrypt_test(), which results in a bogus value if more than one report a nonzero value (e.g., two reporting -2 (-ENOENT) end up reporting -4 (-EINTR)). Instead, keep track of the minimum return value reported by any subtest.

Hopefully for 6.3 we will be able to line up a driver to use it. In drivers land, i915 enables DG2 support by default now, and nouveau has a big stability refactoring and initial ampere support, AMD includes new hw IP support and should build on ARM again. There is also an ofdrm driver to take over offb on platforms it's used. Stuff outside my tree, the dma-buf patches hit a few places, the vc4 firmware changes also do, and i915 has some interactions with MEI for discrete GPUs. I think all of those should have been acked/reviewed by relevant parties.
