* crypto: aes - Precompute tablesHerbert Xu2008-12-251-90/+1055
| | | | | | | | | | | The tables used by the various AES algorithms are currently computed at run-time. This has created an init ordering problem because some AES algorithms may be registered before the tables have been initialised. This patch gets around this whole thing by precomputing the tables.

* crypto: testmgr - Correct comment about deflate parametersGeert Uytterhoeven2008-12-251-1/+1
| | | | | | | | | | The comment for the deflate test vectors says the winbits parameter is 11, while the deflate module actually uses -11 (a negative window bits parameter enables the raw deflate format instead of the zlib format). Correct this, to avoid confusion about the format used. Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: des3_ede - permit weak keys unless REQ_WEAK_KEY setJarod Wilson2008-12-251-2/+3
| | | | | | | | | | | | | | | | | While its a slightly insane to bypass the key1 == key2 || key2 == key3 check in triple-des, since it reduces it to the same strength as des, some folks do need to do this from time to time for backwards compatibility with des. My own case is FIPS CAVS test vectors. Many triple-des test vectors use a single key, replicated 3x. In order to get the expected results, des3_ede_setkey() needs to only reject weak keys if the CRYPTO_TFM_REQ_WEAK_KEY flag is set. Also sets a more appropriate RES flag when a weak key is found.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ANSI X9.31 PRNG docs aren't particularly clear on how to increment DT, but empirical testing shows we're incrementing from the wrong end. A 10,000 iteration Monte Carlo RNG test currently winds up not getting the expected result. From http://csrc.nist.gov/groups/STM/cavp/documents/rng/RNGVS.pdf : # CAVS 4.3 # ANSI931 MCT [X9.31] [AES 128-Key] COUNT = 0 Key = 9f5b51200bf334b5d82be8c37255c848 DT = 6376bbe52902ba3b67c925fa701f11ac V = 572c8e76872647977e74fbddc49501d1 R = 48e9bd0d06ee18fbe45790d5c3fc9b73 Currently, we get 0dd08496c4f7178bfa70a2161a79459a after 10000 loops.

* crypto: ansi_cprng - Avoid incorrect extra call to _get_more_prng_bytesJarod Wilson2008-12-251-6/+11

For example, the following test vector (complete with expected result) from http://csrc.nist.gov/groups/STM/cavp/documents/rng/RNGVS.pdf ...

One approach to fixing this would be to alter some byte_count checks in get_prng_bytes, but it would mean the last DEFAULT_BLK_SZ bytes would be copied a byte at a time, rather than in a single memcpy, so a slightly more involved, equally functional, and ultimately more efficient way of fixing this was suggested to me by Neil, which I'm submitting here. All of the RNGVS ANSI X9.31 AES128 VST test vectors I've passed through ansi_cprng are now returning the expected results with this change.

* libcrc32c: Move implementation to crypto crc32cHerbert Xu2008-12-252-5/+112
| | | | | | | | | | | | | | This patch swaps the role of libcrc32c and crc32c. Previously the implementation was in libcrc32c and crc32c was a wrapper. Now the code is in crc32c and libcrc32c just calls the crypto layer. The reason for the change is to tap into the algorithm selection capability of the crypto API so that optimised implementations such as the one utilising Intel's CRC32C instruction can be used where available.

* crypto: api - Call type show function before legacy for procHerbert Xu2008-12-251-7/+13
| | | | | | | | | | This patch makes /proc/crypto call the type-specific show function if one is present before calling the legacy show functions for cipher/digest/compress. This allows us to reuse the type values for those legacy types. In particular, hash and digest will share one type value while shash is phased in as the default hash type.

* crypto: hash - Add import/export interfaceHerbert Xu2008-12-252-0/+28
| | | | | | | | | | | | It is often useful to save the partial state of a hash function so that it can be used as a base for two or more computations. The most prominent example is HMAC where all hashes start from a base determined by the key. Having an import/export interface means that we only have to compute that base once rather than for each message. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hash - Export shash through ahashHerbert Xu2008-12-251-0/+143
| | | | | | | | This patch allows shash algorithms to be used through the ahash interface. This is required before we can convert digest algorithms over to shash. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hash - Add shash interfaceHerbert Xu2008-12-252-0/+240
| | | | | | | | | | | | | | | | | | | | | | | | The shash interface replaces the current synchronous hash interface. It improves over hash in two ways. Firstly shash is reentrant, meaning that the same tfm may be used by two threads simultaneously as all hashing state is stored in a local descriptor. The other enhancement is that shash no longer takes scatter list entries. This is because shash is specifically designed for synchronous algorithms and as such scatter lists are unnecessary. All existing hash users will be converted to shash once the algorithms have been completely converted. There is also a new finup function that combines update with final. This will be extended to ahash once the algorithm conversion is done. This is also the first time that an algorithm type has their own registration function. Existing algorithm types will be converted to this way in due course. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Rebirth of crypto_alloc_tfmHerbert Xu2008-12-252-0/+110
| | | | | | | | | | | | | | | This patch reintroduces a completely revamped crypto_alloc_tfm. The biggest change is that we now take two crypto_type objects when allocating a tfm, a frontend and a backend. In fact this simply formalises what we've been doing behind the API's back. For example, as it stands crypto_alloc_ahash may use an actual ahash algorithm or a crypto_hash algorithm. Putting this in the API allows us to do this much more cleanly. The existing types will be converted across gradually. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Move type exit function into crypto_tfmHerbert Xu2008-12-251-7/+6
| | | | | | | | | | | | | | | | | | | | | | | The type exit function needs to undo any allocations done by the type init function. However, the type init function may differ depending on the upper-level type of the transform (e.g., a crypto_blkcipher instantiated as a crypto_ablkcipher). So we need to move the exit function out of the lower-level structure and into crypto_tfm itself. As it stands this is a no-op since nobody uses exit functions at all. However, all cases where a lower-level type is instantiated as a different upper-level type (such as blkcipher as ablkcipher) will be converted such that they allocate the underlying transform and use that instead of casting (e.g., crypto_ablkcipher casted into crypto_blkcipher). That will need to use a different exit function depending on the upper-level type. This patch also allows the type init/exit functions to call (or not) cra_init/cra_exit instead of always calling them from the top level. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ansi_cprng - Allow resetting of DT valueNeil Horman2008-12-251-3/+13
| | | | | | | | | | | | | | This is a patch that was sent to me by Jarod Wilson, marking off my outstanding todo to allow the ansi cprng to set/reset the DT counter value in a cprng instance. Currently crytpo_rng_reset accepts a seed byte array which is interpreted by the ansi_cprng as a {V key} tuple. This patch extends that tuple to now be {V key DT}, with DT an optional value during reset. This patch also fixes a bug we noticed in which the offset of the key area of the seed is started at DEFAULT_PRNG_KSZ rather than DEFAULT_BLK_SZ as it should be.

* crypto: testmgr - Trigger a panic when self test fails in FIPS modeNeil Horman2008-12-251-1/+6
| | | | | | | | | | | | | The FIPS specification requires that should self test for any supported crypto algorithm fail during operation in fips mode, we need to prevent the use of any crypto functionality until such time as the system can be re-initialized. Seems like the best way to handle that would be to panic the system if we were in fips mode and failed a self test. This patch implements that functionality. I've built and run it successfully.

Since the destination may be reused as a source, ensure that it is only mapped once and that it is mapped bidirectionally. This appears to add ugliness on the unmap side in that it always reads back the destination address from the descriptor, but gcc can determine that dma_unmap is a nop and not emit the code that calculates its arguments.

| * crypto: skcipher - Use RNG interface instead of get_random_bytesHerbert Xu2008-08-294-13/+75
| | | | | | | | | | | | | | This patch makes the IV generators use the new RNG interface so that the user can pick an RNG other than the default get_random_bytes. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: rng - RNG interface and implementationNeil Horman2008-08-295-1/+628
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a random number generator interface as well as a cryptographic pseudo-random number generator based on AES. It is meant to be used in cases where a deterministic CPRNG is required. One of the first applications will be as an input in the IPsec IV generation process.

| * crypto: api - Add fips_enable flagNeil Horman2008-08-295-0/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.

| * crypto: skcipher - Move IV generators into their own modulesHerbert Xu2008-08-294-35/+18
| | | | | | | | | | | | | | | | This patch moves the default IV generators into their own modules in order to break a dependency loop between cryptomgr, rng, and blkcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: cryptomgr - Test ciphers using ECBHerbert Xu2008-08-292-50/+169
| | | | | | | | | | | | | | | | | | | | | | As it is we only test ciphers when combined with a mode. That means users that do not invoke a mode of operations may get an untested cipher. This patch tests all ciphers using the ECB mode so that simple cipher users such as ansi-cprng are also protected. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: api - Use test infrastructureHerbert Xu2008-08-295-42/+259
| | | | | | | | | | | | | | | | This patch makes use of the new testing infrastructure by requiring algorithms to pass a run-time test before they're made available to users. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
