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.

2015-10-15crypto: keywrap - add key wrapping block chaining modeStephan Mueller1-0/+419
This patch implements the AES key wrapping as specified in NIST SP800-38F and RFC3394. The implementation covers key wrapping without padding. IV handling: The caller does not provide an IV for encryption, but must obtain the IV after encryption which would serve as the first semblock in the ciphertext structure defined by SP800-38F. Conversely, for decryption, the caller must provide the first semiblock of the data as the IV and the following blocks as ciphertext. The key wrapping is an authenticated decryption operation. The caller will receive EBADMSG during decryption if the authentication failed. Albeit the standards define the key wrapping for AES only, the template can be used with any other block cipher that has a block size of 16 bytes. During initialization of the template, that condition is checked. Any cipher not having a block size of 16 bytes will cause the initialization to fail.

2015-09-25X.509: Don't strip leading 00's from key ID when constructing key descriptionDavid Howells1-4/+0
Don't strip leading zeros from the crypto key ID when using it to construct the struct key description as the signature in kernels up to and including 4.2 matched this aspect of the key. This means that 1 in 256 keys won't actually match if their key ID begins with 00. The key ID is stored in the module signature as binary and so must be converted to text in order to invoke request_key() - but it isn't stripped at this point. Something like this is likely to be observed in dmesg when the key is loaded: [ 1.572423] Loaded X.509 cert 'Build time autogenerated kernel key: 62a7c3d2da278be024da4af8652c071f3fea33' followed by this when we try and use it: [ 1.646153] Request for unknown module key 'Build time autogenerated kernel key: 0062a7c3d2da278be024da4af8652c071f3fea33' err -11 The 'Loaded' line should show an extra '00' on the front of the hex string. This problem should not affect 4.3-rc1 and onwards because there the key should be matched on one of its auxiliary identities rather than the key struct's description string.

2015-09-01PKCS#7: Add OIDs for sha224, sha284 and sha512 hash algos and use themDavid Howells2-0/+17
Add OIDs for sha224, sha284 and sha512 hash algos and use them to select the hashing algorithm. Without this, something like the following error might get written to dmesg: [ 31.829322] PKCS7: Unknown OID: [32] 2.16.840.1.101.3.4.2.3 [ 31.829328] PKCS7: Unknown OID: [180] 2.16.840.1.101.3.4.2.3 [ 31.829330] Unsupported digest algo: 55 Where the 55 on the third line is OID__NR indicating an unknown OID.

2015-08-25crypto: algif_aead - fix for multiple operations on AF_ALG socketsLars Persson1-0/+1
The tsgl scatterlist must be re-initialized after each operation. Otherwise the sticky bits in the page_link will corrupt the list with pre-mature termination or false chaining. Signed-off-by: Lars Persson <larper@axis.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-21crypto: testmgr - Use new skcipher interfaceHerbert Xu1-29/+32
This patch replaces uses of blkcipher and ablkcipher with the new skcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-21crypto: skcipher - Add top-level skcipher interfaceHerbert Xu2-0/+246
This patch introduces the crypto skcipher interface which aims to replace both blkcipher and ablkcipher. It's very similar to the existing ablkcipher interface. The main difference is the removal of the givcrypt interface. In order to make the transition easier for blkcipher users, there is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place a request on the stack for synchronous transforms.

2015-08-17crypto: null - Add missing Kconfig tristate for NULL2Herbert Xu1-0/+1
This patch adds a missing tristate statement to Kconfig for the new CRYPTO_NULL2 option. Fixes: 149a39717dcc ("crypto: aead - Add type-safe geniv init/exit helpers") Reported-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-17crypto: null - Use NULL2 in MakefileHerbert Xu1-1/+1
The Kconfig option NULL2 has been added as CRYPTO_MANAGER now depends indirectly on NULL2. However, the Makefile was not updated to use the new option, resulting in potential build failures when only NULL2 is enabled.
