Merge branch 'modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

2012-10-14T20:39:34Z

Pull module signing support from Rusty Russell: "module signing is the highlight, but it's an all-over David Howells frenzy..." Hmm "Magrathea: Glacier signing key". Somebody has been reading too much HHGTTG. * 'modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (37 commits) X.509: Fix indefinite length element skip error handling X.509: Convert some printk calls to pr_devel asymmetric keys: fix printk format warning MODSIGN: Fix 32-bit overflow in X.509 certificate validity date checking MODSIGN: Make mrproper should remove generated files. MODSIGN: Use utf8 strings in signer's name in autogenerated X.509 certs MODSIGN: Use the same digest for the autogen key sig as for the module sig MODSIGN: Sign modules during the build process MODSIGN: Provide a script for generating a key ID from an X.509 cert MODSIGN: Implement module signature checking MODSIGN: Provide module signing public keys to the kernel MODSIGN: Automatically generate module signing keys if missing MODSIGN: Provide Kconfig options MODSIGN: Provide gitignore and make clean rules for extra files MODSIGN: Add FIPS policy module: signature checking hook X.509: Add a crypto key parser for binary (DER) X.509 certificates MPILIB: Provide a function to read raw data into an MPI X.509: Add an ASN.1 decoder X.509: Add simple ASN.1 grammar compiler ...

KEYS: Provide signature verification with an asymmetric key

2012-10-08T03:20:15Z

Provide signature verification using an asymmetric-type key to indicate the public key to be used. The API is a single function that can be found in crypto/public_key.h: int verify_signature(const struct key *key, const struct public_key_signature *sig) The first argument is the appropriate key to be used and the second argument is the parsed signature data: struct public_key_signature { u8 *digest; u16 digest_size; enum pkey_hash_algo pkey_hash_algo : 8; union { MPI mpi[2]; struct { MPI s; /* m^d mod n */ } rsa; struct { MPI r; MPI s; } dsa; }; }; This should be filled in prior to calling the function. The hash algorithm should already have been called and the hash finalised and the output should be in a buffer pointed to by the 'digest' member. Any extra data to be added to the hash by the hash format (eg. PGP) should have been added by the caller prior to finalising the hash. It is assumed that the signature is made up of a number of MPI values. If an algorithm becomes available for which this is not the case, the above structure will have to change. It is also assumed that it will have been checked that the signature algorithm matches the key algorithm. Signed-off-by: David Howells Signed-off-by: Rusty Russell

crypto: cast6 - prepare generic module for optimized implementations

Rename cast6 module to cast6_generic to allow autoloading of optimized implementations. Generic functions and s-boxes are exported to be able to use them within optimized implementations. Signed-off-by: Johannes Goetzfried Signed-off-by: Herbert Xu

crypto: add crypto_[un]register_shashes for [un]registering multiple shash entries at once

crypto: user - Fix lookup of algorithms with IV generator

2012-03-29T11:52:47Z

We lookup algorithms with crypto_alg_mod_lookup() when instantiating via crypto_add_alg(). However, algorithms that are wrapped by an IV genearator (e.g. aead or genicv type algorithms) need special care. The userspace process hangs until it gets a timeout when we use crypto_alg_mod_lookup() to lookup these algorithms. So export the lookup functions for these algorithms and use them in crypto_add_alg(). Signed-off-by: Steffen Klassert Signed-off-by: Herbert Xu
