* crypto: shash - Move null setkey check to registration timeHerbert Xu2009-07-11
| | | | | | | This patch moves the run-time null setkey check to shash_prepare_alg just like we did for finup/digest. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: sha256_generic - Add export/import supportHerbert Xu2009-07-11
| | | | | | | | This patch adds export/import support to sha256_generic. The exported type is defined by struct sha256_state, which is basically the entire descriptor state of sha256_generic. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: shash - Move finup/digest null checks to registration timeHerbert Xu2009-07-11
| | | | | | | This patch moves the run-time null finup/digest checks to the shash_prepare_alg function which is run at registration time. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Export/import hash state onlyHerbert Xu2009-07-11
| | | | | | | | | | | | | This patch replaces the full descriptor export with an export of the partial hash state. This allows the use of a consistent export format across all implementations of a given algorithm. This is useful because a number of cases require the use of the partial hash state, e.g., PadLock can use the SHA1 hash state to get around the fact that it can only hash contiguous data chunks.

* crypto: api - Add crypto_attr_alg2 helperHerbert Xu2009-07-08
| | | | | | | | This patch adds the helper crypto_attr_alg2 which is similar to crypto_attr_alg but takes an extra frontend argument. This is intended to be used by new style algorithm types such as shash. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Add spawn supportHerbert Xu2009-07-08
| | | | | | | This patch adds the functions needed to create and use shash spawns, i.e., to use shash algorithms in a template. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Add new style spawn supportHerbert Xu2009-07-08
| | | | | | | | | This patch modifies the spawn infrastructure to support new style algorithms like shash. In particular, this means storing the frontend type in the spawn and using crypto_create_tfm to allocate the tfm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Add shash_instanceHerbert Xu2009-07-08
| | | | | | | | | This patch adds shash_instance and the associated alloc/free functions. This is meant to be an instance that with a shash algorithm under it. Note that the instance itself doesn't have to be shash. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Add crypto_alloc_instance2Herbert Xu2009-07-07
| | | | | | | | | | | This patch adds a new argument to crypto_alloc_instance which sets aside some space before the instance for use by algorithms such as shash that place type-specific data before crypto_alg. For compatibility the function has been renamed so that existing users aren't affected. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Add new template create functionHerbert Xu2009-07-07
| | | | | | | | | | | This patch introduces the template->create function intended to replace the existing alloc function. The intention is for create to handle the registration directly, whereas currently the caller of alloc has to handle the registration. This allows type-specific code to be run prior to registration.

* crypto: ansi_prng - Use just a BH lockSebastian Andrzej Siewior2009-07-03
| | | | | | | | | | | | The current code uses a mix of sping_lock() & spin_lock_irqsave(). This can lead to deadlock with the correct timming & cprng_get_random() + cprng_reset() sequence. I've converted them to bottom half locks since all three user grab just a BH lock so this runs probably in softirq :) Signed-off-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Allow implementation-specific testsHerbert Xu2009-07-02

* crypto: skcipher - Change default sync geniv on SMP to eseqivHerbert Xu2009-06-25
| | | | | | | | | | | | | | | | | As it stands we use chainiv for sync algorithms and eseqiv for async algorithms. However, when there is more than one CPU chainiv forces all processing to be serialised which is usually not what you want. Also, the added overhead of eseqiv isn't that great. Therefore this patch changes the default sync geniv on SMP machines to eseqiv. For the odd situation where the overhead is unacceptable then chainiv is still available as an option. Note that on UP machines chainiv is still preferred over eseqiv for sync algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: skcipher - Fix request for sync algorithmsHerbert Xu2009-06-25
| | | | | | | | | | | When a sync givcipher algorithm is requested, if an async version of the same algorithm already exists, then we will loop forever without ever constructing the sync version based on a blkcipher. This is because we did not include the requested type/mask when getting a larval for the geniv algorithm that is to be constructed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* random: Add optional continuous repetition test to entropy store based rngsNeil Horman2009-06-18
| | | | | | | | | | | | | | | | FIPS-140 requires that all random number generators implement continuous self tests in which each extracted block of data is compared against the last block for repetition. The ansi_cprng implements such a test, but it would be nice if the hw rng's did the same thing. Obviously its not something thats always needed, but it seems like it would be a nice feature to have on occasion. I've written the below patch which allows individual entropy stores to be flagged as desiring a continuous test to be run on them as is extracted. By default this option is off, but is enabled in the event that fips mode is selected during bootup.

| | | | | | | | | | | | | | | | | | | | | | As it stands we will each test hash vector both linearly and as a scatter list if applicable. This means that we cannot have vectors longer than a page, even with scatter lists. This patch fixes this by skipping test vectors with np != 0 when testing linearly.

| * crypto: testmgr - Check all test vector lengthsHerbert Xu2009-06-02
| | | | | | | | | | | | | | | | | | | | As we cannot guarantee the availability of contiguous pages at run-time, all test vectors must either fit within a page, or use scatter lists.

| * crypto: tcrypt - Do not exit on success in fips modeJarod Wilson2009-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, the tcrypt module always exits with an -EAGAIN upon successfully completing all the tests its been asked to run. In fips mode, integrity checking is done by running all self-tests from the initrd, and its much simpler to check the ret from modprobe for success than to scrape dmesg and/or /proc/crypto. Simply stay loaded, giving modprobe a retval of 0, if self-tests all pass and we're in fips mode. A side-effect of tracking success/failure for fips mode is that in non-fips mode, self-test failures will return the actual failure return codes, rather than always returning -EAGAIN, which seems more correct anyway. The tcrypt_test() portion of the patch is dependent on my earlier pair of patches that skip non-fips algs in fips mode, at least to achieve the fully intended behavior. Nb: testing this patch against the cryptodev tree revealed a test failure for sha384, which I have yet to look into...

One caveat: des isn't actually allowed anymore, but des (and thus also ecb(des)) has to be permitted, because disallowing them results in des3_ede being unable to properly register (see des module init func). Also, crc32 isn't technically on the fips approved list, but I think it gets used in various places that necessitate it being allowed. This list is based on http://csrc.nist.gov/groups/STM/cavp/index.html Important note: allowed/approved here does NOT mean "validated", just that its an alg that *could* be validated.

| * crypto: testmgr - Dynamically allocate xbuf and axbufHerbert Xu2009-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently allocate temporary memory that is used for testing statically. This renders the testing engine non-reentrant. As algorithms may nest, i.e., one may construct another in order to carry out a part of its operation, this is unacceptable. For example, it has been reported that an AEAD implementation allocates a cipher in its setkey function, which causes it to fail during testing as the temporary memory is overwritten. This patch replaces the static memory with dynamically allocated buffers. We need a maximum of 16 pages so this slightly increases the chances of an algorithm failing due to memory shortage. However, as testing usually occurs at registration, this shouldn't be a big problem. Reported-by: Shasi Pulijala <spulijala@amcc.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

New and improved v2, without strncmp crap. Doesn't need to touch a flag though, due to not moving the notest label around anymore. Applies atop '[PATCH v2] crypto: catch base cipher self-test failures in fips mode'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because kernel_fpu_begin() and kernel_fpu_end() operations are too slow, the performance gain of general mode implementation + aes-aesni is almost all compensated. The AES-NI support for more modes are implemented as follow: - Add a new AES algorithm implementation named __aes-aesni without kernel_fpu_begin/end() - Use fpu(<mode>(AES)) to provide kenrel_fpu_begin/end() invoking - Add <mode>(AES) ablkcipher, which uses cryptd(fpu(<mode>(AES))) to defer cryption to cryptd context in soft_irq context. Now the ctr, lrw, pcbc and xts support are added. Performance testing based on dm-crypt shows that cryption time can be reduced to 50% of general mode implementation + aes-aesni implementation.
