2016-01-30crypto: crc32 - Rename generic implementationHerbert Xu2-2/+3
The generic crc32 implementation is currently called crc32. This is a problem because it clashes with the lib implementation of crc32. This patch renames the crypto crc32 to crc32_generic so that it is consistent with crc32c. An alias for the driver is also added. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2016-01-27crypto: jitterentropy - always select CRYPTO_RNGArnd Bergmann1-0/+1
When building the jitterentropy driver by itself, we get a link error when CRYPTO_RNG is not enabled as well: crypto/built-in.o: In function `jent_mod_init': jitterentropy-kcapi.c:(.init.text+0x98): undefined reference to `crypto_register_rng' crypto/built-in.o: In function `jent_mod_exit': jitterentropy-kcapi.c:(.exit.text+0x60): undefined reference to `crypto_unregister_rng' This adds a 'select CRYPTO_RNG' to CRYPTO_JITTERENTROPY to ensure the API is always there when it's used, not just when DRBG is also enabled. CRYPTO_DRBG would set it implicitly through CRYPTO_JITTERENTROPY now, but this leaves it in place to make it explicit what the driver does.

While converting ecryptfs over to skcipher I found that it needs to pick a default key size if one isn't given. Rather than having it poke into the guts of the algorithm to get max_keysize, let's provide a helper that is meant to give a sane default (just in case we ever get an algorithm that has no maximum key size).

The Authenticode specification is a paragon amongst technical documents, and has this pearl of wisdom to offer: --------------------------------- Authenticode-Specific SignerInfo UnauthenticatedAttributes Structures The following Authenticode-specific data structures are present in SignerInfo authenticated attributes. SpcSpOpusInfo SpcSpOpusInfo is identified by SPC_SP_OPUS_INFO_OBJID (1.3.6.1.4.1.311.2.1.12) and is defined as follows: SpcSpOpusInfo ::= SEQUENCE { programName [0] EXPLICIT SpcString OPTIONAL, moreInfo [1] EXPLICIT SpcLink OPTIONAL, } --#public-- SpcSpOpusInfo has two fields: programName This field contains the program description: If publisher chooses not to specify a description, the SpcString structure contains a zero-length program name. If the publisher chooses to specify a description, the SpcString structure contains a Unicode string. moreInfo This field is set to an SPCLink structure that contains a URL for a Web site with more information about the signer. The URL is an ASCII string. --------------------------------- Which is to say that this is an optional *unauthenticated* field which may be present in the Authenticated Attribute list. This is not how pkcs7 is supposed to work, so when David implemented this, he didn't appreciate the subtlety the original spec author was working with, and missed the part of the sublime prose that says this Authenticated Attribute is an Unauthenticated Attribute. As a result, the code in question simply takes as given that the Authenticated Attributes should be authenticated. But this one should not, individually. Because it says it's not authenticated. It still has to hash right so the TBS digest is correct. So it is both authenticated and unauthenticated, all at once. Truly, a wonder of technical accomplishment. Additionally, pesign's implementation has always attempted to be compatible with the signatures emitted from contemporary versions of Microsoft's signtool.exe. During the initial implementation, Microsoft signatures always produced the same values for SpcSpOpusInfo - {U"Microsoft Windows", "http://www.microsoft.com"} - without regard to who the signer was. Sometime between Windows 8 and Windows 8.1 they stopped including the field in their signatures altogether, and as such pesign stopped producing them in commits c0c4da6 and d79cb0c, sometime around June of 2012. The theory here is that anything that breaks with pesign signatures would also be breaking with signtool.exe sigs as well, and that'll be a more noticed problem for firmwares parsing it, so it'll get fixed. The fact that we've done exactly this bug in Linux code is first class, grade A irony. So anyway, we should not be checking this field for presence or any particular value: if the field exists, it should be at the right place, but aside from that, as long as the hash matches the field is good.

2016-01-19crypto: crc32c - Fix crc32c soft dependencyJean Delvare1-1/+0
I don't think it makes sense for a module to have a soft dependency on itself. This seems quite cyclic by nature and I can't see what purpose it could serve. OTOH libcrc32c calls crypto_alloc_shash("crc32c", 0, 0) so it pretty much assumes that some incarnation of the "crc32c" hash algorithm has been loaded. Therefore it makes sense to have the soft dependency there (as crc-t10dif does.) Cc: stable@vger.kernel.org Cc: Tim Chen <tim.c.chen@linux.intel.com> Cc: "David S.

2016-01-18crypto: af_alg - Disallow bind/setkey/... after accept(2)Herbert Xu1-3/+32
Each af_alg parent socket obtained by socket(2) corresponds to a tfm object once bind(2) has succeeded. An accept(2) call on that parent socket creates a context which then uses the tfm object. Therefore as long as any child sockets created by accept(2) exist the parent socket must not be modified or freed. This patch guarantees this by using locks and a reference count on the parent socket. Any attempt to modify the parent socket will fail with EBUSY.

This option creates IMA MOK and blacklist keyrings. IMA MOK is an intermediate keyring that sits between .system and .ima keyrings, effectively forming a simple CA hierarchy. To successfully import a key into .ima_mok it must be signed by a key which CA is in .system keyring. On turn any key that needs to go in .ima keyring must be signed by CA in either .system or .ima_mok keyrings. IMA MOK is empty at kernel boot. IMA blacklist keyring contains all revoked IMA keys. It is consulted before any other keyring. If the search is successful the requested operation is rejected and error is returned to the caller.

2015-12-09crypto: skcipher - Copy iv from desc even for 0-len walksJason A. Donenfeld2-2/+2
Some ciphers actually support encrypting zero length plaintexts. For example, many AEAD modes support this. The resulting ciphertext for those winds up being only the authentication tag, which is a result of the key, the iv, the additional data, and the fact that the plaintext had zero length. The blkcipher constructors won't copy the IV to the right place, however, when using a zero length input, resulting in some significant problems when ciphers call their initialization routines, only to find that the ->iv parameter is uninitialized. One such example of this would be using chacha20poly1305 with a zero length input, which then calls chacha20, which calls the key setup routine, which eventually OOPSes due to the uninitialized ->iv member.

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.
