crypto: api - Add instance free function to crypto_type

2015-07-14T06:56:45Z

Currently the task of freeing an instance is given to the crypto template. However, it has no type information on the instance so we have to resort to checking type information at runtime. This patch introduces a free function to crypto_type that will be used to free an instance. This can then be used to free an instance in a type-safe manner. Signed-off-by: Herbert Xu

crypto: api - Remove unused __crypto_dequeue_request

2015-07-14T06:56:44Z

The function __crypto_dequeue_request is completely unused. Signed-off-by: Herbert Xu

crypto: api - Include alignment in crypto_alg_extsize

2015-06-03T02:48:34Z

This patch ensures that the tfm context always has enough extra memory to ensure that it is aligned according to cra_alignment. Signed-off-by: Herbert Xu

crypto: api - Add crypto_grab_spawn primitive

2015-05-13T02:31:25Z

This patch adds a new primitive crypto_grab_spawn which is meant to replace crypto_init_spawn and crypto_init_spawn2. Under the new scheme the user no longer has to worry about reference counting the alg object before it is subsumed by the spawn. It is pretty much an exact copy of crypto_grab_aead. Prior to calling this function spawn->frontend and spawn->inst must have been set. Signed-off-by: Herbert Xu

crypto: api - Fix build error when modules are disabled

2015-04-26T06:33:15Z

The commit 59afdc7b32143528524455039e7557a46b60e4c8 ("crypto: api - Move module sig ifdef into accessor function") broke the build when modules are completely disabled because we directly dereference module->name. This patch fixes this by using the accessor function module_name. Reported-by: Fengguang Wu Signed-off-by: Herbert Xu

crypto: api - Include linux/fips.h

2015-04-23T06:18:08Z

All users of fips_enabled should include linux/fips.h directly instead of getting it through internal.h. Signed-off-by: Herbert Xu

crypto: api - Move module sig ifdef into accessor function

2015-04-23T06:18:07Z

Currently we're hiding mod->sig_ok under an ifdef in open code. This patch adds a module_sig_ok accessor function and removes that ifdef. Signed-off-by: Herbert Xu Acked-by: Rusty Russell

crypto: api - Add crypto_alg_extsize helper

2015-04-21T02:19:54Z

This patch adds a crypto_alg_extsize helper that can be used by algorithm types such as pcompress and shash. Signed-off-by: Herbert Xu

crypto: fix broken crypto_register_instance() module handling

2015-04-16T03:26:16Z

Commit 9c521a200bc3 ("crypto: api - remove instance when test failed") tried to grab a module reference count before the module was even set. Worse, it then goes on to free the module reference count after it is set so you quickly end up with a negative module reference count which prevents people from using any instances belonging to that module. This patch moves the module initialisation before the reference count. Reported-by: Linus Torvalds Signed-off-by: Herbert Xu Signed-off-by: Linus Torvalds

crypto: api - remove instance when test failed

2015-04-10T13:39:38Z

A cipher instance is added to the list of instances unconditionally regardless of whether the associated test failed. However, a failed test implies that during another lookup, the cipher instance will be added to the list again as it will not be found by the lookup code. That means that the list can be filled up with instances whose tests failed. Note: tests only fail in reality in FIPS mode when a cipher is not marked as fips_allowed=1. This can be seen with cmac(des3_ede) that does not have a fips_allowed=1. When allocating the cipher, the allocation fails with -ENOENT due to the missing fips_allowed=1 flag (which causes the testmgr to return EINVAL). Yet, the instance of cmac(des3_ede) is shown in /proc/crypto. Allocating the cipher again fails again, but a 2nd instance is listed in /proc/crypto. The patch simply de-registers the instance when the testing failed. Signed-off-by: Stephan Mueller Signed-off-by: Herbert Xu
