* padata: Remove padata_get_cpumaskSteffen Klassert2010-07-31
| | | | | | | | | | | | A function that copies the padata cpumasks to a user buffer is a bit error prone. The cpumask can change any time so we can't be sure to have the right cpumask when using this function. A user who is interested in the padata cpumasks should register to the padata cpumask notifier chain instead. Users of padata_get_cpumask are already updated, so we can remove it.

* crypto: pcrypt - Update pcrypt cpumask according to the padata cpumask notifierSteffen Klassert2010-07-31
| | | | | | | | | The padata cpumask change notifier passes a padata_cpumask to the notifier chain. So we use this cpumask instead of asking padata for the cpumask. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: pcrypt - Rename pcrypt_instanceSteffen Klassert2010-07-31
| | | | | | | | | | | 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.

* padata: Rearrange set_cpumask functionsSteffen Klassert2010-07-31
| | | | | | | | | | padata_set_cpumask needs to be protected by a lock. We make __padata_set_cpumasks unlocked and static. So this function can be used by the exported and locked padata_set_cpumask and padata_set_cpumasks functions.

* padata: Rename padata_alloc functionsSteffen Klassert2010-07-31
| | | | | | | | | | | | We rename padata_alloc to padata_alloc_possible because this function allocates a padata_instance and uses the cpu_possible mask for parallel and serial workers. Also we rename __padata_alloc to padata_alloc to avoid to export underlined functions. Underlined functions are considered to be private to padata. Users are updated accordingly.

* crypto: pcrypt - Dont calulate a callback cpu on empty callback cpumaskSteffen Klassert2010-07-26
| | | | | | | | | If the callback cpumask is empty, we crash with a division by zero when we try to calculate a callback cpu. So we don't update the callback cpu in pcrypt_do_parallel if the callback cpumask is empty.

* padata: Check for valid cpumasksSteffen Klassert2010-07-26
| | | | | | | | | | Now that we allow to change the cpumasks from userspace, we have to check for valid cpumasks in padata_do_parallel. This patch adds the necessary check. This fixes a division by zero crash if the parallel cpumask contains no active cpu.

* padata: Allocate cpumask dependend recources in any caseSteffen Klassert2010-07-26
| | | | | | | | | | | The cpumask separation work assumes the cpumask dependend recources present regardless of valid or invalid cpumasks. With this patch we allocate the cpumask dependend recources in any case. This fixes two NULL pointer dereference crashes in padata_replace and in padata_get_cpumask.

* padata: Make two separate cpumasksDan Kruchinin2010-07-19
| | | | | | | | | | | | | | 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.

* padata: simplify serialization mechanismSteffen Klassert2010-07-14
| | | | | | | | | | | | | | We count the number of processed objects on a percpu basis, so we need to go through all the percpu reorder queues to calculate the sequence number of the next object that needs serialization. This patch changes this to count the number of processed objects global. So we can calculate the sequence number and the percpu reorder queue of the next object that needs serialization without searching through the percpu reorder queues. This avoids some accesses to memory of foreign cpus. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* padata: make padata_do_parallel to return zero on successSteffen Klassert2010-07-14
| | | | | | | | | | | | | To return -EINPROGRESS on success in padata_do_parallel was considered to be odd. This patch changes this to return zero on success. Also the only user of padata, pcrypt is adapted to convert a return of zero to -EINPROGRESS within the crypto layer. This also removes the pcrypt fallback if padata_do_parallel was called on a not running padata instance as we can't handle it anymore. This fallback was unused, so it's save to remove it.

* padata: Handle empty padata cpumasksSteffen Klassert2010-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug when the padata cpumask does not intersect with the active cpumask. In this case we get a division by zero in padata_alloc_pd and we end up with a useless padata instance. Padata can end up with an empty cpumask for two reasons: 1. A user removed the last cpu that belongs to the padata cpumask and the active cpumask. 2. The last cpu that belongs to the padata cpumask and the active cpumask goes offline. We introduce a function padata_validate_cpumask to check if the padata cpumask does intersect with the active cpumask. If the cpumasks do not intersect we mark the instance as invalid, so it can't be used. We do not allocate the cpumask dependend recources in this case. This fixes the division by zero and keeps the padate instance in a consistent state. It's not possible to trigger this bug by now because the only padata user, pcrypt uses always the possible cpumask.

| | | | | | | | | | This patch makes padata_stop to block until the padata instance is unused. Also we split padata_stop to a locked and a unlocked version.

* padata: Check for valid padata instance on startSteffen Klassert2010-07-14
| | | | | | | | | | | | This patch introduces the PADATA_INVALID flag which is checked on padata start. This will be used to mark a padata instance as invalid, if the padata cpumask does not intersect with the active cpumask. we change padata_start to return an error if the PADATA_INVALID is set. Also we adapt the only padata user, pcrypt to this change. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: twofish: Rename twofish to twofish_generic and add an aliasJoachim Fritschi2010-06-03
| | | | | | | | | | | | | | | This fixes the broken autoloading of the corresponding twofish assembler ciphers on x86 and x86_64 if they are available. The module name of the generic implementation was in conflict with the alias in the assembler modules. The generic twofish c implementation is renamed to twofish_generic according to the other algorithms with assembler implementations and an module alias is added for 'twofish'. You can now load 'twofish' giving you the best implementation by priority, 'twofish-generic' to get the c implementation or 'twofish-asm' to get the assembler version of cipher.

The code in i2400m_rx_edata() wasn't properly following access protocol, performing an invalid check on i2400m->rx_roq (which is cleared to NULL when the refcount drops to zero). As such, it was missing to detect when the data structure is no longer valid and oopsing with a NULL pointer dereference. This commit fixes said check by verifying, under the rx_lock spinlock, that i2400m->rx_roq is non-NULL and then increasing the reference count before dropping the spinlock.
