* crypto: skcipher - Use RNG interface instead of get_random_bytesHerbert Xu2008-08-29
| | | | | | | 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 Horman2008-08-29
| | | | | | | | | | | | 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 Horman2008-08-29
| | | | | | | | | | | | | | | 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 Xu2008-08-29
| | | | | | | | 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 Xu2008-08-29
| | | | | | | | | | | 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 Xu2008-08-29
| | | | | | | | 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>
* crypto: cryptomgr - Add test infrastructureHerbert Xu2008-08-29
| | | | | | | | This patch moves the newly created alg_test infrastructure into cryptomgr. This shall allow us to use it for testing at algorithm registrations. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: tcrypt - Add alg_test interfaceHerbert Xu2008-08-29
| | | | | | | | | | | | | This patch creates a new interface algorithm testing. A test can be requested for a particular implementation of an algorithm. This is achieved by taking both the name of the algorithm and that of the implementation. The all-inclusive test has also been rewritten to no longer require a duplicate listing of all algorithms with tests. In that process a number of missing tests have also been discovered and rectified. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: tcrypt - Abort and only log if there is an errorHerbert Xu2008-08-29
| | | | | | | | | | | | The info printed is a complete waste of space when there is no error since it doesn't tell us anything that we don't already know. If there is an error, we can also be more verbose. In case that there is an error, this patch also aborts the test and returns the error to the caller. In future this will be used to algorithms at registration time. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crc32c - Use Intel CRC32 instructionAustin Zhang2008-08-29
| | | | | | | | | | | | | From NHM processor onward, Intel processors can support hardware accelerated CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set. The patch detects the availability of the feature, and chooses the most proper way to calculate CRC32c checksum. Byte code instructions are used for compiler compatibility. No MMX / XMM registers is involved in the implementation.

* crypto: tcrypt - Avoid using contiguous pagesHerbert Xu2008-08-29
| | | | | | | | | | If tcrypt is to be used as a run-time integrity test, it needs to be more resilient in a hostile environment. For a start allocating 32K of physically contiguous memory is definitely out. This patch teaches it to use separate pages instead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: api - Export crypto_alg_lookup instead of __crypto_alg_lookupHerbert Xu2008-08-29
| | | | | | | Since the only user of __crypto_alg_lookup is doing exactly what crypto_alg_lookup does, we can now the latter in lieu of the former. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * | [ARM] Skip memory holes in FLATMEM when reading /proc/pagetypeinfoMel Gorman2008-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ordinarily, memory holes in flatmem still have a valid memmap and is safe to use. However, an architecture (ARM) frees up the memmap backing memory holes on the assumption it is never used. /proc/pagetypeinfo reads the whole range of pages in a zone believing that the memmap is valid and that pfn_valid will return false if it is not. On ARM, freeing the memmap breaks the page->zone linkages even though pfn_valid() returns true and the kernel can oops shortly afterwards due to accessing a bogus struct zone *. This patch lets architectures say when FLATMEM can have holes in the memmap. Rather than an expensive check for valid memory, /proc/pagetypeinfo will confirm that the page linkages are still valid by checking page->zone is still the expected zone. The lookup of page_zone is safe as there is a limited range of memory that is accessed when calling page_zone. Even if page_zone happens to return the correct zone, the impact is that the counters in /proc/pagetypeinfo are slightly off but fragmentation monitoring is unlikely to be relevant on an embedded system.
