gcc-10: avoid shadowing standard library 'free()' in crypto

2020-05-20T06:22:25Z

commit 1a263ae60b04de959d9ce9caea4889385eefcc7b upstream. gcc-10 has started warning about conflicting types for a few new built-in functions, particularly 'free()'. This results in warnings like: crypto/xts.c:325:13: warning: conflicting types for built-in function ‘free’; expected ‘void(void *)’ [-Wbuiltin-declaration-mismatch] because the crypto layer had its local freeing functions called 'free()'. Gcc-10 is in the wrong here, since that function is marked 'static', and thus there is no chance of confusion with any standard library function namespace. But the simplest thing to do is to just use a different name here, and avoid this gcc mis-feature. [ Side note: gcc knowing about 'free()' is in itself not the mis-feature: the semantics of 'free()' are special enough that a compiler can validly do special things when seeing it. So the mis-feature here is that gcc thinks that 'free()' is some restricted name, and you can't shadow it as a local static function. Making the special 'free()' semantics be a function attribute rather than tied to the name would be the much better model ] Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

crypto: rename sm3-256 to sm3 in hash_algo_name

2020-02-18T12:35:49Z

The name sm3-256 is defined in hash_algo_name in hash_info, but the algorithm name implemented in sm3_generic.c is sm3, which will cause the sm3-256 algorithm to be not found in some application scenarios of the hash algorithm, and an ENOENT error will occur. For example, IMA, keys, and other subsystems that reference hash_algo_name all use the hash algorithm of sm3.

crypto/testmgr: enable selftests for paes-s390 ciphers

2020-02-13T16:53:24Z

This patch enables the selftests for the s390 specific protected key AES (PAES) cipher implementations: * cbc-paes-s390 * ctr-paes-s390 * ecb-paes-s390 * xts-paes-s390 PAES is an AES cipher but with encrypted ('protected') key material. However, the paes ciphers are able to derive an protected key from clear key material with the help of the pkey kernel module. So this patch now enables the generic AES tests for the paes ciphers. Under the hood the setkey() functions rearrange the clear key values as clear key token and so the pkey kernel module is able to provide protected key blobs from the given clear key values. The derived protected key blobs are then used within the paes cipers and should produce the very same results as the generic AES implementation with the clear key values. The s390-paes cipher testlist entries are surrounded by #if IS_ENABLED(CONFIG_CRYPTO_PAES_S390) because they don't make any sense on non s390 platforms or without the PAES cipher implementation.

2020-02-05T09:00:57Z

The library code uses CRYPTO_MANAGER_DISABLE_TESTS to conditionalize its tests, but the library code can also exist without CRYPTO_MANAGER. That means on minimal configs, the test code winds up being built with no way to disable it. Signed-off-by: Jason A. Donenfeld Signed-off-by: Herbert Xu

treewide: remove redundant IS_ERR() before error code check

'PTR_ERR(p) == -E*' is a stronger condition than IS_ERR(p). Hence, IS_ERR(p) is unneeded.
