crypto/pcrypt: Replace synchronize_rcu_bh() with synchronize_rcu()

2018-11-27T17:18:59Z

Now that synchronize_rcu() waits for bh-disable regions of code as well as RCU read-side critical sections, the synchronize_rcu_bh() in pcrypt_cpumask_change_notify() can be replaced by synchronize_rcu(). This commit therefore makes this change. Signed-off-by: Paul E. McKenney Cc: Steffen Klassert Cc: Acked-by: Herbert Xu

pcrypt: use format specifier in kobject_add

2018-11-09T09:41:39Z

Passing string 'name' as the format specifier is potentially hazardous because name could (although very unlikely to) have a format specifier embedded in it causing issues when parsing the non-existent arguments to these. Follow best practice by using the "%s" format string for the string 'name'. Cleans up clang warning: crypto/pcrypt.c:397:40: warning: format string is not a string literal (potentially insecure) [-Wformat-security] Fixes: a3fb1e330dd2 ("pcrypt: Added sysfs interface to pcrypt") Signed-off-by: Colin Ian King Signed-off-by: Herbert Xu

crypto: pcrypt - fix freeing pcrypt instances

2017-12-22T08:02:47Z

pcrypt is using the old way of freeing instances, where the ->free() method specified in the 'struct crypto_template' is passed a pointer to the 'struct crypto_instance'. But the crypto_instance is being kfree()'d directly, which is incorrect because the memory was actually allocated as an aead_instance, which contains the crypto_instance at a nonzero offset. Thus, the wrong pointer was being kfree()'d. Fix it by switching to the new way to free aead_instance's where the ->free() method is specified in the aead_instance itself.

crypto: aead - Remove CRYPTO_ALG_AEAD_NEW flag

2015-08-17T08:53:53Z

This patch removes the CRYPTO_ALG_AEAD_NEW flag now that everyone has been converted. Signed-off-by: Herbert Xu

crypto: pcrypt - Propagate new AEAD implementation flag

2015-07-14T06:56:45Z

This patch allows the CRYPTO_ALG_AEAD_NEW flag to be propagated. It also restores the ASYNC bit that went missing during the AEAD conversion. Signed-off-by: Herbert Xu

crypto: pcrypt - Add support for new AEAD interface

2015-06-03T02:48:35Z

This patch converts pcrypt over to the new AEAD interface. Signed-off-by: Herbert Xu

crypto: pcrypt - Make tfm_count an atomic_t

2015-05-25T10:41:25Z

The variable tfm_count is accessed by multiple threads without locking. This patch converts it to an atomic_t. Signed-off-by: Herbert Xu

crypto: pcrypt - Use crypto_grab_aead

2015-05-22T03:25:49Z

As AEAD has switched over to using frontend types, the function crypto_init_spawn must not be used since it does not specify a frontend type. Otherwise it leads to a crash when the spawn is used. This patch fixes it by switching over to crypto_grab_aead instead. Fixes: 5d1d65f8bea6 ("crypto: aead - Convert top level interface to new style") Signed-off-by: Herbert Xu

crypto: pcrypt - Use crypto_aead_set_reqsize helper

2015-05-13T02:31:41Z

This patch uses the crypto_aead_set_reqsize helper to avoid directly touching the internals of aead. Signed-off-by: Herbert Xu
