* keys: change asymmetric keys to use common hash definitionsDmitry Kasatkin2013-10-256-30/+20
| | | | | | | | | | | | This patch makes use of the newly defined common hash algorithm info, replacing, for example, PKEY_HASH with HASH_ALGO. Changelog: - Lindent fixes - Mimi CC: David Howells <dhowells@redhat.com> Signed-off-by: Dmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
* crypto: provide single place for hash algo informationDmitry Kasatkin2013-10-253-0/+60
| | | | | | | | | | | | | | This patch provides a single place for information about hash algorithms, such as hash sizes and kernel driver names, which will be used by IMA and the public key code. Changelog: - Fix sparse and checkpatch warnings - Move hash algo enums to uapi for userspace signing functions.

* KEYS: verify a certificate is signed by a 'trusted' keyMimi Zohar2013-09-251-1/+80
| | | | | | | | | | | | Only public keys, with certificates signed by an existing 'trusted' key on the system trusted keyring, should be added to a trusted keyring. This patch adds support for verifying a certificate's signature. This is derived from David Howells pkcs7_request_asymmetric_key() patch.

* KEYS: Set the asymmetric-key type default search methodDavid Howells2013-09-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | The keyring expansion patches introduces a new search method by which key_search() attempts to walk directly to the key that has exactly the same description as the requested one. However, this causes inexact matching of asymmetric keys to fail. The solution to this is to select iterative rather than direct search as the default search type for asymmetric keys. As an example, the kernel might have a key like this: Magrathea: Glacier signing key: 6a2a0f82bad7e396665f465e4e3e1f9bd24b1226 and: keyctl search <keyring-ID> asymmetric id:d24b1226 should find the key, despite that not being its exact description.

* X.509: Remove certificate date checksDavid Howells2013-09-251-38/+0
| | | | | | | | | | | | | | | Remove the certificate date checks that are performed when a certificate is parsed. There are two checks: a valid from and a valid to. The first check is causing a lot of problems with system clocks that don't keep good time and the second places an implicit expiry date upon the kernel when used for module signing, so do we really need them?

* X.509: Embed public_key_signature struct and create filler functionDavid Howells2013-09-253-55/+74
| | | | | | | | | | | | | | | Embed a public_key_signature struct in struct x509_certificate, eliminating now unnecessary fields, and split x509_check_signature() to create a filler function for it that attaches a digest of the signed data and an MPI that represents the signature data. x509_free_certificate() is then modified to deal with these. Whilst we're at it, export both x509_check_signature() and the new x509_get_sig_params().

Note that to make this configure correctly, the public key part must be dependent on the RSA module rather than the other way round.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, even with a softdep some distros fail to include the necessary modules in the initrd. Therefore this patch adds a fallback path to restore existing behaviour where we cannot load the new crypto crct10dif algorithm. In order to do this, the underlying crct10dif has been split out from the crypto implementation so that it can be used on the fallback path. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

The previous 8-way twofish/AVX implementation is therefore faster and this implementation should be removed.
