* crypto: testmgr - mark more algorithms as FIPS compliantMarcus Meissner2016-02-061-0/+7

* crypto: testmgr - fix out of bound read in __test_aead()Jerome Marchand2016-02-061-2/+3
| | | | | | | | | | | | __test_aead() reads MAX_IVLEN bytes from template[i].iv, but the actual length of the initialisation vector can be shorter. The length of the IV is already calculated earlier in the function. Let's just reuses that. Also the IV length is currently calculated several time for no reason. Let's fix that too. This fix an out-of-bound error detected by KASan. Signed-off-by: Jerome Marchand <jmarchan@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: tcrypt - Use ahashHerbert Xu2016-02-061-224/+15
| | | | | | | | | This patch removes the last user of the obsolete crypto_hash interface, tcrypt, by simply switching it over to ahash. In fact it already has all the code there so it's just a matter of calling the ahash speed test code with the right mask. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: engine - Introduce the block request crypto engine frameworkBaolin Wang2016-02-013-0/+359
| | | | | | | | | | | | | | | | | | | Now block cipher engines need to implement and maintain their own queue/thread for processing requests, moreover currently helpers provided for only the queue itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they don't help with the mechanics of driving the hardware (things like running the request immediately, DMA map it or providing a thread to process the queue in) even though a lot of that code really shouldn't vary that much from device to device. Thus this patch provides a mechanism for pushing requests to the hardware as it becomes free that drivers could use. And this framework is patterned on the SPI code and has worked out well there. (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/ drivers/spi/spi.c?id=ffbbdd21329f3e15eeca6df2d4bc11c04d9d91c0) Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crc32 - Rename generic implementationHerbert Xu2016-01-302-2/+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>

* crypto: jitterentropy - always select CRYPTO_RNGArnd Bergmann2016-01-271-0/+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.

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.

So get rid of module.h since it drags in a lot of other headers and adds to the preprocessing load. It does export some symbols though, so we'll need to ensure it has export.h present instead.
