* crypto: vmac - New hash algorithm for intel_txt supportShane Wang2009-09-021-0/+9
| | | | | | | | This patch adds VMAC (a fast MAC) support into crypto framework. Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: Joseph Cihula <joseph.cihula@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Allow implementation-specific testsHerbert Xu2009-07-021-4/+13
| | | | | | | | This patch adds the support for testing specific implementations. This should only be used in very specific situations. Right now this means specific implementations of random number generators. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Remove hash size checkHerbert Xu2009-06-241-4/+0
| | | | | | | Until hash test vectors grow longer than 256 bytes, the only purpose of the check is to generate a gcc warning. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Allow hash test vectors longer than a pageHerbert Xu2009-06-021-3/+8
| | | | | | | | | | | 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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Check all test vector lengthsHerbert Xu2009-06-021-0/+25
| | | | | | | | | | 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. In some cases vectors were not checked as to whether they fit inside a page. This patch adds all the missing checks. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: compress - Return produced bytes in crypto_{,de}compress_{update,final}Geert Uytterhoeven2009-06-021-47/+70
| | | | | | | | | If crypto_{,de}compress_{update,final}() succeed, return the actual number of bytes produced instead of zero, so their users don't have to calculate that theirselves.

* crypto: testmgr - Skip algs not flagged fips_allowed in fips modeJarod Wilson2009-06-021-0/+8
| | | | | | | | | | | Because all fips-allowed algorithms must be self-tested before they can be used, they will all have entries in testmgr.c's alg_test_descs[]. Skip self-tests for any algs not flagged as fips_approved and return -EINVAL when in fips mode.

* crypto: testmgr - Mark algs allowed in fips modeJarod Wilson2009-06-021-0/+23
| | | | | | | | | | | | | | | | | | | | | | Set the fips_allowed flag in testmgr.c's alg_test_descs[] for algs that are allowed to be used when in fips mode. 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 - Add ctr(aes) test vectorsJarod Wilson2009-06-021-4/+19
| | | | | | | | Now with multi-block test vectors, all from SP800-38A, Appendix F.5. Also added ctr(aes) to case 10 in tcrypt. Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Dynamically allocate xbuf and axbufHerbert Xu2009-06-021-48/+60
| | | | | | | | | | | | | | | | | | | 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>
* crypto: testmgr - Print self-test pass notices in fips modeJarod Wilson2009-06-021-0/+4
| | | | | | | | | | | | | | | | | | | According to our FIPS CAVS testing lab guru, when we're in fips mode, we must print out notices of successful self-test completion for every alg to be compliant. 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'. Personally, I wouldn't mind seeing this info printed out regardless of whether or not we're in fips mode, I think its useful info, but will stick with only in fips mode for now.

* crypto: testmgr - Add ansi_cprng test vectorsJarod Wilson2009-06-021-0/+9
| | | | | | | | | | | | | | | | | Add ANSI X9.31 Continuous Pseudo-Random Number Generator (AES mode), aka 'ansi_cprng' test vectors, taken from Appendix B.2.9 and B.2.10 of the NIST RNGVS document, found here: http://csrc.nist.gov/groups/STM/cavp/documents/rng/RNGVS.pdf Successfully tested against both the cryptodev-2.6 tree and a Red Hat Enterprise Linux 5.4 kernel, via 'modprobe tcrypt mode=150'. The selection of 150 was semi-arbitrary, didn't seem like it should go any place in particular, so I started a new range for rng tests.

* crypto: testmgr - Add infrastructure for ansi_cprng self-testsJarod Wilson2009-06-021-0/+89
| | | | | | | | | | | | | | | | Add some necessary infrastructure to make it possible to run self-tests for ansi_cprng. The bits are likely very specific to the ANSI X9.31 CPRNG in AES mode, and thus perhaps should be named more specifically if/when we grow additional CPRNG support... Successfully tested against the cryptodev-2.6 tree and a Red Hat Enterprise Linux 5.x kernel with the follow-on patch that adds the actual test vectors.

* crypto: testmgr - Add self-tests for rfc4309(ccm(aes))Jarod Wilson2009-06-021-0/+15
| | | | | | | | | | | | | | | Add an array of encryption and decryption + verification self-tests for rfc4309(ccm(aes)). Test vectors all come from sample FIPS CAVS files provided to Red Hat by a testing lab. Unfortunately, all the published sample vectors in RFC 3610 and NIST Special Publication 800-38C contain nonce lengths that the kernel's rfc4309 implementation doesn't support, so while using some public domain vectors would have been preferred, its not possible at this time.

| | | | | | | | | | | When self-testing (de)compression algorithms, make sure the actual size of the (de)compressed output data matches the expected output size. Otherwise, in case the actual output size would be smaller than the expected output size, the subsequent buffer compare test would still succeed, and no error would be reported.

* 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.

* crypto: cryptomgr - Test ciphers using ECBHerbert Xu2008-08-291-46/+168
| | | | | | | | | | | 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>
