2015-12-10crypto: drbg - constify drbg_state_ops structuresJulia Lawall1-3/+3
The drbg_state_ops structures are never modified, so declare them as const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-12-09crypto: chacha20poly1305 - Skip encryption/decryption for 0-lenJason A. Donenfeld1-0/+8
If the length of the plaintext is zero, there's no need to waste cycles on encryption and decryption. Using the chacha20poly1305 construction for zero-length plaintexts is a common way of using a shared encryption key for AAD authentication. Signed-off-by: Jason A.

2015-12-09crypto: rsa - RSA padding algorithmAndrzej Zaborowski3-1/+633
This patch adds PKCS#1 v1.5 standard RSA padding as a separate template. This way an RSA cipher with padding can be obtained by instantiating "pkcs1pad(rsa)". The reason for adding this is that RSA is almost never used without this padding (or OAEP) so it will be needed for either certificate work in the kernel or the userspace, and I also hear that it is likely implemented by hardware RSA in which case hardware implementations of the whole of pkcs1pad(rsa) can be provided.

2015-12-09crypto: akcipher - add akcipher declarations needed by templates.Andrzej Zaborowski1-1/+33
Add a struct akcipher_instance and struct akcipher_spawn similar to how AEAD declares them and the macros for converting to/from crypto_instance/crypto_spawn. Also add register functions to avoid exposing crypto_akcipher_type. Signed-off-by: Andrew Zaborowski <andrew.zaborowski@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-12-04crypto: cryptd - Assign statesize properlyWang, Rui Y1-0/+1
cryptd_create_hash() fails by returning -EINVAL. It is because after 68418efba ("crypto: ahash - ensure statesize is non-zero") all ahash drivers must have a non-zero statesize. This patch fixes the problem by properly assigning the statesize. Signed-off-by: Rui Wang <rui.y.wang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-11-17crypto: rsa - only require output buffers as big as needed.Andrzej Zaborowski1-24/+0
rhe RSA operations explicitly left-align the integers being written skipping any leading zero bytes, but still require the output buffers to include just enough space for the integer + the leading zero bytes. Since the size of integer + the leading zero bytes (i.e. the key modulus size) can now be obtained more easily through crypto_akcipher_maxsize change the operations to only require as big a buffer as actually needed if the caller has that information. The semantics for request->dst_len don't change. Signed-off-by: Andrew Zaborowski <andrew.zaborowski@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-11-12X.509: Fix the time validation [ver #2]David Howells1-5/+7
This fixes CVE-2015-5327. It affects kernels from 4.3-rc1 onwards. Fix the X.509 time validation to use month number-1 when looking up the number of days in that month. Also put the month number validation before doing the lookup so as not to risk overrunning the array. This can be tested by doing the following: cat <<EOF | openssl x509 -outform DER | keyctl padd asymmetric "" @s -----BEGIN CERTIFICATE----- MIIDbjCCAlagAwIBAgIJAN/lUld+VR4hMA0GCSqGSIb3DQEBCwUAMCkxETAPBgNV BAoMCGxvY2FsLWNhMRQwEgYDVQQDDAtzaWduaW5nIGtleTAeFw0xNTA5MDEyMTMw MThaFw0xNjA4MzEyMTMwMThaMCkxETAPBgNVBAoMCGxvY2FsLWNhMRQwEgYDVQQD DAtzaWduaW5nIGtleTCCASIwDQYJKoZIhvcNAQEBBQADggEPADCCAQoCggEBANrn crcMfMeG67nagX4+m02Xk9rkmsMKI5XTUxbikROe7GSUVJ27sPVPZp4mgzoWlvhh jfK8CC/qhEhwep8Pgg4EJZyWOjhZb7R97ckGvLIoUC6IO3FC2ZnR7WtmWDgo2Jcj VlXwJdHhKU1VZwulh81O61N8IBKqz2r/kDhIWiicUCUkI/Do/RMRfKAoDBcSh86m gOeIAGfq62vbiZhVsX5dOE8Oo2TK5weAvwUIOR7OuGBl5AqwFlPnXQolewiHzKry THg9e44HfzG4Mi6wUvcJxVaQT1h5SrKD779Z5+8+wf1JLaooetcEUArvWyuxCU59 qxA4lsTjBwl4cmEki+cCAwEAAaOBmDCBlTAMBgNVHRMEBTADAQH/MAsGA1UdDwQE AwIHgDAdBgNVHQ4EFgQUyND/eKUis7ep/hXMJ8iZMdUhI+IwWQYDVR0jBFIwUIAU yND/eKUis7ep/hXMJ8iZMdUhI+KhLaQrMCkxETAPBgNVBAoMCGxvY2FsLWNhMRQw EgYDVQQDDAtzaWduaW5nIGtleYIJAN/lUld+VR4hMA0GCSqGSIb3DQEBCwUAA4IB AQAMqm1N1yD5pimUELLhT5eO2lRdGUfTozljRxc7e2QT3RLk2TtGhg65JFFN6eml XS58AEPVcAsSLDlR6WpOpOLB2giM0+fV/eYFHHmh22yqTJl4YgkdUwyzPdCHNOZL hmSKeY9xliHb6PNrNWWtZwhYYvRaO2DX4GXOMR0Oa2O4vaYu6/qGlZOZv3U6qZLY wwHEJSrqeBDyMuwN+eANHpoSpiBzD77S4e+7hUDJnql4j6xzJ65+nWJ89fCrQypR 4sN5R3aGeIh3QAQUIKpHilwek0CtEaYERgc5m+jGyKSc1rezJW62hWRTaitOc+d5 G5hh+9YpnYcxQHEKnZ7rFNKJ -----END CERTIFICATE----- EOF If it works, it emit a key ID; if it fails, it should give a bad message error.

2015-10-20crypto: api - Only abort operations on fatal signalHerbert Xu4-6/+6
Currently a number of Crypto API operations may fail when a signal occurs. This causes nasty problems as the caller of those operations are often not in a good position to restart the operation. In fact there is currently no need for those operations to be interrupted by user signals at all. All we need is for them to be killable. This patch replaces the relevant calls of signal_pending with fatal_signal_pending, and wait_for_completion_interruptible with wait_for_completion_killable, respectively.
