* | crypto: rsa - limit supported key lengthsTadeusz Struk2015-07-171-1/+25
| | | | | | | | | | | | | | | | | | Introduce constrains for RSA keys lengths. Only key lengths of 512, 1024, 1536, 2048, 3072, and 4096 bits will be supported. Signed-off-by: Tadeusz Struk <tadeusz.struk@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | crypto: testmgr - Disable rfc4309 test and convert test vectorsHerbert Xu2015-07-172-219/+1413
| | | | | | | | | | | | | | | | | | This patch disables the rfc4309 test while the conversion to the new seqiv calling convention takes place. It also replaces the rfc4309 test vectors with ones that will work with the new IV convention. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | crypto: gcm - Use new IV conventionHerbert Xu2015-07-141-37/+77
| | | | | | | | | | | | | | | | This patch converts rfc4106 to the new calling convention where the IV is now part of the AD and needs to be skipped. This patch also makes use of the new type-safe way of freeing instances. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* | crypto: tcrypt - Add support for new IV conventionHerbert Xu2015-07-141-3/+8

* | crypto: seqiv - Replace seqniv with seqivHerbert Xu2015-07-141-15/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the seqniv generator with seqiv when the underlying algorithm understands the new calling convention. This not only makes more sense as now seqiv is solely responsible for IV generation rather than also determining how the IV is going to be used, it also allows for optimisations in the underlying implementation. For example, the space for the IV could be used to add padding for authentication. This patch also removes the unnecessary copying of IV to dst during seqiv decryption as the IV is part of the AD and not cipher text. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* | crypto: echainiv - Fix encryption conventionHerbert Xu2015-07-141-13/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug where we were incorrectly including the IV in the AD during encryption. The IV must remain in the plain text for it to be encrypted. During decryption there is no need to copy the IV to dst because it's now part of the AD. This patch removes an unncessary check on authsize which would be performed by the underlying decrypt call. Finally this patch makes use of the type-safe init/exit functions.

* | crypto: aead - Add type-safe function for freeing instancesHerbert Xu2015-07-141-0/+13
| | | | | | | | | | | | | | | | | | This patch adds a type-safe function for freeing AEAD instances to struct aead_instance. This replaces the existing free function in struct crypto_template which does not know the type of the instance that it's freeing. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* | crypto: api - Add instance free function to crypto_typeHerbert Xu2015-07-141-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | crypto: cryptd - Fix AEAD request context corruptionHerbert Xu2015-07-071-4/+8
|/ | | | | | | | | | | The AEAD version of cryptd uses the same context for its own state as well as that of the child. In doing so it did not maintain the proper ordering, thus resulting in potential state corruption where the child will overwrite the state stored by cryptd. This patch fixes and also sets the request size properly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The core of the Jitter RNG is intended to be compiled with -O0. To ensure that the Jitter RNG can be compiled on all architectures, separate out the RNG core into a stand-alone C file that can be compiled with -O0 which does not depend on any kernel include file. As no kernel includes can be used in the C file implementing the core RNG, any dependencies on kernel code must be extracted. A second file provides the link to the kernel and the kernel crypto API that can be compiled with the regular compile options of the kernel.

* | | | crypto: algif_aead - Temporarily disable all AEAD algorithmsHerbert Xu2015-06-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the AEAD conversion is still ongoing, we do not yet wish to export legacy AEAD implementations to user-space, as their calling convention will change. This patch actually disables all AEAD algorithms because some of them (e.g., cryptd) will need to be modified to propagate this flag. Subsequent patches will reenable them on an individual basis.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bit CRYPTO_ALG_INTERNAL was added to stop af_alg from accessing internal algorithms. However, af_alg itself was never modified to actually stop that bit from being used by the user. Therefore the user could always override it by specifying the relevant bit in the type and/or mask. This patch silently discards the bit in both type and mask. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

As the RNG Is only needed for IPsec, we should not let this prevent use of ciphers without IV generators, e.g., for disk encryption. This patch postpones the RNG allocation to the init function so that one failure during early boot does not make the RNG unavailable for all subsequent users of the same cipher. More importantly, it lets the cipher live even if RNG allocation fails. Of course we no longer offer IV generation and which will fail with an error if invoked. But all other cipher capabilities will function as usual. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new crypto_user command that allows the admin to delete the crypto system RNG.

* | | | crypto: rng - Do not free default RNG when it becomes unusedHerbert Xu2015-06-221-4/+23

This was OK when the IV generators would latch onto the RNG at instance creation time and keep it until the instance is torn down. Now that IV generators only keep the RNG reference during init time this scheme causes the default RNG to come and go at a high frequencey. This is highly undesirable as we want to keep a single RNG in use unless the admin wants it to be removed. This patch changes the scheme so that the system RNG once allocated is never removed unless a specifically requested. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* | | | crypto: skcipher - Allow givencrypt to be NULLHerbert Xu2015-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently for skcipher IV generators they must provide givencrypt as that is the whole point. We are currently replacing skcipher IV generators with explicit IV generators. In order to maintain backwards compatibility, we need to allow the IV generators to still function as a normal skcipher when the RNG Is not present (e.g., in the initramfs during boot). IOW everything but givencrypt and givdecrypt will still work but those two will fail. Therefore this patch assigns a default givencrypt that simply returns an error should it be NULL.

A few have performance impacts which hould mostly be positive, but RAID5 (in particular) can be very work-load ensitive... We'll have to wait and see. Highlights: - "experimental" code for managing md/raid1 across a cluster using DLM. Code is not ready for general use and triggers a WARNING if used. However it is looking good and mostly done and having in mainline will help co-ordinate development. - RAID5/6 can now batch multiple (4K wide) stripe_heads so as to handle a full (chunk wide) stripe as a single unit. - RAID6 can now perform read-modify-write cycles which should help performance on larger arrays: 6 or more devices. - RAID5/6 stripe cache now grows and shrinks dynamically. The value set is used as a minimum. - Resync is now allowed to go a little faster than the 'mininum' when there is competing IO.

The raid6 rmw path should work the same as the already existing raid5 logic. So emulate the prexor handling/flags and split functions as needed. 1) Enable xor_syndrome() in the async layer. 2) Split ops_run_prexor() into RAID4/5 and RAID6 logic. Xor the syndrome at the start of a rmw run as we did it before for the single parity. 3) Take care of rmw run in ops_run_reconstruct6(). Again process only the changed pages to get syndrome back into sync. 4) Enhance set_syndrome_sources() to fill NULL pages if we are in a rmw run. The lower layers will calculate start & end pages from that and call the xor_syndrome() correspondingly. 5) Adapt the several places where we ignored Q handling up to now.
