| * | crypto: gcm - Fix IV buffer size in crypto_gcm_setkeyOndrej Mosnáček2016-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cipher block size for GCM is 16 bytes, and thus the CTR transform used in crypto_gcm_setkey() will also expect a 16-byte IV. However, the code currently reserves only 8 bytes for the IV, causing an out-of-bounds access in the CTR transform. This patch fixes the issue by setting the size of the IV buffer to 16 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In FIPS mode, additional restrictions may apply. If these restrictions are violated, the kernel will panic(). This patch allows test vectors for symmetric ciphers to be marked as to be skipped in FIPS mode. Together with the patch, the XTS test vectors where the AES key is identical to the tweak key is disabled in FIPS mode. This test vector violates the FIPS requirement that both keys must be different.

| * | crypto: rsa - allow keys >= 2048 bits in FIPS modeStephan Mueller2016-08-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With a public notification, NIST now allows the use of RSA keys with a modulus >= 2048 bits. The new rule allows any modulus size >= 2048 bits provided that either 2048 or 3072 bits are supported at least so that the entire RSA implementation can be CAVS tested. This patch fixes the inability to boot the kernel in FIPS mode, because certs/x509.genkey defines a 4096 bit RSA key per default. This key causes the RSA signature verification to fail in FIPS mode without the patch below.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When calling the DRBG health test in FIPS mode, the Jitter RNG is not yet present in the kernel crypto API which will cause the instantiation to fail and thus the health test to fail. As the health tests cover the enforcement of various thresholds, invoke the functions that are supposed to enforce the thresholds directly. This patch also saves precious seed.

As the latter has long ago been fixed to call scatterwalk_advance directly, we can remove this unnecessary offset adjustment. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: scatterwalk - Fix test in scatterwalk_doneHerbert Xu2016-07-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is more data to be processed, the current test in scatterwalk_done may prevent us from calling pagedone even when we should. In particular, if we're on an SG entry spanning multiple pages where the last page is not a full page, we will incorrectly skip calling pagedone on the second last page. This patch fixes this by adding a separate test for whether we've reached the end of a page. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: scatterwalk - Add no-copy support to copychunksHerbert Xu2016-07-181-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function ablkcipher_done_slow is pretty much identical to scatterwalk_copychunks except that it doesn't actually copy as the processing hasn't been completed yet. This patch allows scatterwalk_copychunks to be used in this case by specifying out == 2. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: scatterwalk - Remove scatterwalk_bytes_sglenHerbert Xu2016-07-181-22/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the now unused scatterwalk_bytes_sglen. Anyone using this out-of-tree should switch over to sg_nents_for_len. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: skcipher - Remove top-level givcipher interfaceHerbert Xu2016-07-187-1128/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the old crypto_grab_skcipher helper and replaces it with crypto_grab_skcipher2. As this is the final entry point into givcipher this patch also removes all traces of the top-level givcipher interface, including all implicit IV generators such as chainiv. The bottom-level givcipher interface remains until the drivers using it are converted. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: user - Remove crypto_lookup_skcipher callHerbert Xu2016-07-181-36/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As there are no more kernel users of built-in IV generators we can remove the special lookup for skciphers. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts cts over to the skcipher interface. It also optimises the implementation to use one CBC operation for all but the last block, which is then processed separately. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: null - Remove default null blkcipherHerbert Xu2016-07-181-43/+6

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an skcipher null object alongside the existing null blkcipher so that IV generators using it can switch over to skcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts chacha20poly1305 to use the new skcipher interface as opposed to ablkcipher. It also fixes a buglet where we may end up with an async poly1305 when the user asks for a async algorithm. This shouldn't be a problem yet as there aren't any async implementations of poly1305 out there. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
