This will allow filesystems to directly own and control all of their mount options if they so choose. This interface deals only with option identifiers and strings so it should generic enough for any LSM which may come in the future. Filesystems which pass text mount data around in the kernel (almost all of them) need not currently make use of this interface when dealing with SELinux since it will still parse those strings as it always has. I assume future LSM's would do the same. NFS is the primary FS which does not use text mount data and thus must make use of this interface. An LSM would need to implement these functions only if they had mount time options, such as selinux has context= or fscontext=. If the LSM has no mount time options they could simply not implement and let the dummy ops take care of things. An LSM other than SELinux would need to define new option numbers in security.h and any FS which decides to own there own security options would need to be patched to use this new interface for every possible LSM. This is because it was stated to me very clearly that LSM's should not attempt to understand FS mount data and the burdon to understand security should be in the FS which owns the options.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to David Miller for pointing out that the SLAB (or SLOB/SLUB) cache uses the alignment of unsigned long long if the architecture kmalloc/slab alignment macros are not defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates the infrastructure to help the construction of IV generator templates that wrap around AEAD algorithms by adding an IV generator to them.

| * | [CRYPTO] aead: Add givcrypt operationsHerbert Xu2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the underlying givcrypt operations for aead and associated support elements. The rationale is identical to that of the skcipher givcrypt operations, i.e., sometimes only the algorithm knows how the IV should be generated. A new request type aead_givcrypt_request is added which contains an embedded aead_request structure with two new elements to support this operation. The new elements are seq and giv. The seq field should contain a strictly increasing 64-bit integer which may be used by certain IV generators as an input value. The giv field will be used to store the generated IV. It does not need to obey the alignment requirements of the algorithm because it's not used during the operation. The existing iv field must still be available as it will be used to store intermediate IVs and the output IV if chaining is desired. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] skcipher: Create default givcipher instancesHerbert Xu2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes crypto_alloc_ablkcipher/crypto_grab_skcipher always return algorithms that are capable of generating their own IVs through givencrypt and givdecrypt. Each algorithm may specify its default IV generator through the geniv field. For algorithms that do not set the geniv field, the blkcipher layer will pick a default. Currently it's chainiv for synchronous algorithms and eseqiv for asynchronous algorithms. Note that if these wrappers do not work on an algorithm then that algorithm must specify its own geniv or it can't be used at all. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the geniv field which indicates the default IV generator for each algorithm. It should point to a string that is not freed as long as the algorithm is registered. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] skcipher: Add givcrypt operations and givcipher typeHerbert Xu2008-01-11

For example, CBC can use a simple randomly generated IV while modes such as CTR must use an IV generation mechanisms that give a stronger guarantee on the lack of collisions. Furthermore, disk encryption modes have their own IV generation algorithms. Up until now IV generation has been left to the users of the symmetric key cipher API. This is inconvenient as the number of block cipher modes increase because the user needs to be aware of which mode is supposed to be paired with which IV generation algorithm. Therefore it makes sense to integrate the IV generation into the crypto API. This patch takes the first step in that direction by creating two new ablkcipher operations, givencrypt and givdecrypt that generates an IV before performing the actual encryption or decryption. The operations are currently not exposed to the user. That will be done once the underlying functionality has actually been implemented. It also creates the underlying givcipher type. Algorithms that directly generate IVs would use it instead of ablkcipher. All other algorithms (including all existing ones) would generate a givcipher algorithm upon registration. This givcipher algorithm will be constructed from the geniv string that's stored in every algorithm. That string will locate a template which is instantiated by the blkcipher/ablkcipher algorithm in question to give a givcipher algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] skcipher: Add crypto_grab_skcipher interfaceHerbert Xu2008-01-11

The name blkcipher has always been much of a misnomer since it supports stream ciphers too. This patch adds the function crypto_grab_skcipher as a new way of getting an ablkcipher spawn. The problem is that previously we did this in two steps, first getting the algorithm and then calling crypto_init_spawn. This meant that each spawn user had to be aware of what type and mask to use for these two steps. This is difficult and also presents a problem when the type/mask changes as they're about to be for IV generators. The new interface does both steps together just like crypto_alloc_ablkcipher. As a side-effect this also allows us to be stronger on type enforcement for spawns. For now this is only done for ablkcipher but it's trivial to extend for other types. This patch also moves the type/mask logic for skcipher into the helpers crypto_skcipher_type and crypto_skcipher_mask. Finally this patch introduces the function crypto_require_sync to determine whether the user is specifically requesting a sync algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | When allocating ablkcipher/hash objects, we use a mask that's wider than the usual type mask.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it is authsize is an algorithm paramter which cannot be changed at run-time. This is inconvenient because hardware that implements such algorithms would have to register each authsize that they support separately. Since authsize is a property common to all AEAD algorithms, we can add a function setauthsize that sets it at run-time, just like setkey. This patch does exactly that and also changes authenc so that authsize is no longer a parameter of its template. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * | [CRYPTO] ablkcipher: Add distinct ABLKCIPHER typeHerbert Xu2008-01-11

This is suboptimal because ablkcipher refers to two things. On the one hand it refers to the top-level ablkcipher interface with requests. On the other hand it refers to and algorithm type underneath. As it is you cannot request a synchronous block cipher algorithm with the ablkcipher interface on top. This is a problem because we want to be able to eventually phase out the blkcipher top-level interface. This patch fixes this by making ABLKCIPHER its own type, just as we have distinct types for HASH and DIGEST. The type it associated with the algorithm implementation only. Which top-level interface is used for synchronous block ciphers is then determined by the mask that's used. If it's a specific mask then the old blkcipher interface is given, otherwise we go with the new ablkcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the following class iteration functions for driver use: class_for_each_device class_find_device class_for_each_child class_find_child Signed-off-by: Dave Young <hidave.darkstar@gmail.com> Acked-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* | | Driver Core: constify the name passed to platform_device_register_simpleStephen Rothwell2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | This name is just passed to platform_device_alloc which has its parameter declared const. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* | | Driver core: change sysdev classes to use dynamic kobject namesKay Sievers2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup.

* | | Kobject: remove kobject_unregister() as no one uses it anymoreGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | There are no in-kernel users of kobject_unregister() so it should be removed. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* | | Kobject: auto-cleanup on final unrefKay Sievers2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We save the current state in the object itself, so we can do proper cleanup when the last reference is dropped. If the initial reference is dropped, the object will be removed from sysfs if needed, if an "add" event was sent, "remove" will be send, and the allocated resources are released. This allows us to clean up some driver core usage as well as allowing us to do other such changes to the rest of the kernel.

* | | Kset: remove kset_add functionGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | No one is calling this anymore, so just remove it and hard-code the one internal-use of it. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* | | Kobject: remove kobject_register()Greg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function is no longer used by anyone in the kernel, and it prevents the proper sending of the kobject uevent after the needed files are set up by the caller. kobject_init_and_add() can be used in its place.

* | | Kobject: remove kobject_init() as no one uses it anymoreGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old kobject_init() function is on longer in use, so let us remove it from the public scope (kset mess in the kobject.c file still uses it, but that can be cleaned up later very simply.)
