pm_runtime_get_sync() will increment pm usage counter even it failed. Forgetting to call pm_runtime_put_noidle will result in reference leak in stm32_crc_remove, so we should fix it. Signed-off-by: Zheng Yongjun <zhengyongjun3@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2021-12-31crypto: stm32/crc32 - Fix kernel BUG triggered in probe()Marek Vasut1-2/+2
The include/linux/crypto.h struct crypto_alg field cra_driver_name description states "Unique name of the transformation provider. " ... " this contains the name of the chip or provider and the name of the transformation algorithm." In case of the stm32-crc driver, field cra_driver_name is identical for all registered transformation providers and set to the name of the driver itself, which is incorrect. This patch fixes it by assigning a unique cra_driver_name to each registered transformation provider. The kernel crash is triggered when the driver calls crypto_register_shashes() which calls crypto_register_shash(), which calls crypto_register_alg(), which calls __crypto_register_alg(), which returns -EEXIST, which is propagated back through this call chain. Upon -EEXIST from crypto_register_shash(), the crypto_register_shashes() starts unregistering the providers back, and calls crypto_unregister_shash(), which calls crypto_unregister_alg(), and this is where the BUG() triggers due to incorrect cra_refcnt.

2021-12-11crypto: stm32/cryp - fix bugs and crash in testsNicolas Toromanoff1-547/+243
Extra crypto manager auto test were crashing or failling due to 2 reasons: - block in a dead loop (dues to issues in cipher end process management) - crash due to read/write unmapped memory (this crash was also reported when using openssl afalg engine) Rework interrupt management, interrupts are masked as soon as they are no more used: if input buffer is fully consumed, "Input FIFO not full" interrupt is masked and if output buffer is full, "Output FIFO not empty" interrupt is masked. And crypto request finish when input *and* outpout buffer are fully read/write. About the crash due to unmapped memory, using scatterwalk_copychunks() that will map and copy each block fix the issue. Using this api and copying full block will also fix unaligned data access, avoid early copy of in/out buffer, and make useless the extra alignment constraint.

This fixes the lrw autotest if lrw uses the CRYP as the AES block cipher provider (as ecb(aes)). At end of request, CRYP should not update the IV in case of ECB chaining mode. Indeed the ECB chaining mode never uses the IV, but the software LRW chaining mode uses the IV field as a counter and due to the (unexpected) update done by CRYP while the AES block process, the counter get a wrong value when the IV overflow.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers1-1/+2
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

This patch fixes most of the sparse endianness warnings in stm32. The patch itself doesn't change anything apart from markings, but there is some questionable code in stm32_cryp_check_ctr_counter. That function operates on the counters as if they're in CPU order, however, they're then written out as big-endian. This looks like a genuine bug.

2020-01-09crypto: remove CRYPTO_TFM_RES_BAD_KEY_LENEric Biggers1-3/+1
The CRYPTO_TFM_RES_BAD_KEY_LEN flag was apparently meant as a way to make the ->setkey() functions provide more information about errors. However, no one actually checks for this flag, which makes it pointless. Also, many algorithms fail to set this flag when given a bad length key. Reviewing just the generic implementations, this is the case for aes-fixed-time, cbcmac, echainiv, nhpoly1305, pcrypt, rfc3686, rfc4309, rfc7539, rfc7539esp, salsa20, seqiv, and xcbc. But there are probably many more in arch/*/crypto/ and drivers/crypto/. Some algorithms can even set this flag when the key is the correct length. For example, authenc and authencesn set it when the key payload is malformed in any way (not just a bad length), the atmel-sha and ccree drivers can set it if a memory allocation fails, and the chelsio driver sets it for bad auth tag lengths, not just bad key lengths. So even if someone actually wanted to start checking this flag (which seems unlikely, since it's been unused for a long time), there would be a lot of work needed to get it working correctly. But it would probably be much better to go back to the drawing board and just define different return values, like -EINVAL if the key is invalid for the algorithm vs. -EKEYREJECTED if the key was rejected by a policy like "no weak keys". That would be much simpler, less error-prone, and easier to test. So just remove this flag.

Commit 7a7ffe65c8c5 ("crypto: skcipher - Add top-level skcipher interface") dated 20 august 2015 introduced the new skcipher API which is supposed to replace both blkcipher and ablkcipher. While all consumers of the API have been converted long ago, some producers of the ablkcipher remain, forcing us to keep the ablkcipher support routines alive, along with the matching code to expose [a]blkciphers via the skcipher API. So switch this driver to the skcipher API, allowing us to finally drop the ablkcipher code in the near future.
