padata: Make two separate cpumasks The aim of this patch is to make two separate cpumasks for padata parallel and serial workers respectively. It allows user to make more thin and sophisticated configurations of padata framework. For example user may bind parallel and serial workers to non-intersecting CPU groups to gain better performance. Also each padata instance has notifiers chain for its cpumasks now. If either parallel or serial or both masks were changed all interested subsystems will get notification about that. It's especially useful if padata user uses algorithm for callback CPU selection according to serial cpumask.

crypto: pcrypt - Use the online cpumask as the default We use the active cpumask to determine the superset of cpus to use for parallelization. However, the active cpumask is for internal usage of the scheduler and therefore not the appropriate cpumask for these purposes. So use the online cpumask instead.

crypto: pcrypt - fix freeing pcrypt instances 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.

It allows user to make more thin and sophisticated configurations of padata framework. For example user may bind parallel and serial workers to non-intersecting CPU groups to gain better performance. Also each padata instance has notifiers chain for its cpumasks now. If either parallel or serial or both masks were changed all interested subsystems will get notification about that. It's especially useful if padata user uses algorithm for callback CPU selection according to serial cpumask.

padata: Make two separate cpumasks The aim of this patch is to make two separate cpumasks for padata parallel and serial workers respectively. It allows user to make more thin and sophisticated configurations of padata framework. For example user may bind parallel and serial workers to non-intersecting CPU groups to gain better performance. Also each padata instance has notifiers chain for its cpumasks now. If either parallel or serial or both masks were changed all interested subsystems will get notification about that. It's especially useful if padata user uses algorithm for callback CPU selection according to serial cpumask.

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

drivers: avoid format strings in names passed to alloc_workqueue() For the workqueue creation interfaces that do not expect format strings, make sure they cannot accidently be parsed that way. Additionally, clean up calls made with a single parameter that would be handled as a format string.

crypto: pcrypt - Rename pcrypt_instance In the crypto-layer an instance refers usually to a crypto instance. The struct pcrypt_instance is not related to a crypto instance. It rather contains the padata informations, so we rename it to padata_pcrypt. The functions that handle this struct are renamed accordingly.

crypto: pcrypt - Add pcrypt crypto parallelization wrapper This patch adds a parallel crypto template that takes a crypto algorithm and converts it to process the crypto transforms in parallel. For the moment only aead algorithms are supported. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

pcrypt: Added sysfs interface to pcrypt Added sysfs interface to pcrypt. Now pcrypt subsystem creates two sysfs directories with corresponding padata sysfs objects: /sys/kernel/pcrypt/[pencrypt|pdecrypt] Signed-off-by: Dan Kruchinin <dkruchinin@acm.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: run initcalls for generic implementations earlier 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.

crypto: include crypto- module prefix in template This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
