crypto: run initcalls for generic implementations earlier

2019-04-18T14:15:03Z

Use subsys_initcall for registration of all templates and generic algorithm implementations, rather than module_init. Then change cryptomgr to use arch_initcall, to place it before the subsys_initcalls. This is needed so that when both a generic and optimized implementation of an algorithm are built into the kernel (not loadable modules), the generic implementation is registered before the optimized one. Otherwise, the self-tests for the optimized implementation are unable to allocate the generic implementation for the new comparison fuzz tests. Note that on arm, a side effect of this change is that self-tests for generic implementations may run before the unaligned access handler has been installed. So, unaligned accesses will crash the kernel. This is arguably a good thing as it makes it easier to detect that type of bug. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

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.
