* crypto: run initcalls for generic implementations earlierEric Biggers2019-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | Use subsys_initcall for registration of all templates and generic algorithm implementations, rather than module_init. Then change cryptomgr to use arch_initcall, to place it before the subsys_initcalls. This is needed so that when both a generic and optimized implementation of an algorithm are built into the kernel (not loadable modules), the generic implementation is registered before the optimized one. Otherwise, the self-tests for the optimized implementation are unable to allocate the generic implementation for the new comparison fuzz tests. Note that on arm, a side effect of this change is that self-tests for generic implementations may run before the unaligned access handler has been installed. So, unaligned accesses will crash the kernel. This is arguably a good thing as it makes it easier to detect that type of bug.

* crypto: xcbc - Remove VLA usageKees Cook2018-09-041-3/+5
| | | | | | | | | | | | In the quest to remove all stack VLA usage from the kernel[1], this uses the maximum blocksize and adds a sanity check. For xcbc, the blocksize must always be 16, so use that, since it's already being enforced during instantiation.

* crypto: replace FSF address with web source in license noticesMartin Kepplinger2017-11-291-2/+1
| | | | | | | | | | | | | A few years ago the FSF moved and "59 Temple Place" is wrong. Having this still in our source files feels old and unmaintained. Let's take the license statement serious and not confuse users. As https://www.gnu.org/licenses/gpl-howto.html suggests, we replace the postal address with "<http://www.gnu.org/licenses/>".

| | | | | | | | | | | | | | | | | | | This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: xcbc - Fix alignment calculation of xcbc_tfm_ctxSteffen Klassert2009-08-201-3/+5
| | | | | | | | | | | | The alignment calculation of xcbc_tfm_ctx uses alg->cra_alignmask and not alg->cra_alignmask + 1 as it should. This led to frequent crashes during the selftest of xcbc(aes-asm) on x86_64 machines. This patch fixes this. Also we use the alignmask of xcbc and not the alignmask of the underlying algorithm for the alignmnent calculation in xcbc_create now.

* crypto: xcbc - Fix shash conversionHerbert Xu2009-07-221-91/+73
| | | | | | | | | | | Although xcbc was converted to shash, it didn't obey the new requirement that all hash state must be stored in the descriptor rather than the transform. This patch fixes this issue and also optimises away the rekeying by precomputing K2 and K3 within setkey. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [CRYPTO] xcbc: Fix crash when ipsec uses xcbc-mac with big data chunkJoy Latten2008-04-021-8/+9
| | | | | | | | | | | | | | | | | | | | The kernel crashes when ipsec passes a udp packet of about 14XX bytes of data to aes-xcbc-mac. It seems the first xxxx bytes of the data are in first sg entry, and remaining xx bytes are in next sg entry. But we don't check next sg entry to see if we need to go look the page up. I noticed in hmac.c, we do a scatterwalk_sg_next(), to do this check and possible lookup, thus xcbc.c needs to use this routine too. A 15-hour run of an ipsec stress test sending streams of tcp and udp packets of various sizes, using this patch and aes-xcbc-mac completed successfully, so hopefully this fixes the problem.

* [CRYPTO] xcbc: Fix crash with IPsecJoy Latten2008-03-061-1/+5
| | | | | | | | | | | | | | | | | When using aes-xcbc-mac for authentication in IPsec, the kernel crashes. It seems this algorithm doesn't account for the space IPsec may make in scatterlist for authtag. Thus when crypto_xcbc_digest_update2() gets called, nbytes may be less than sg[i].length. Since nbytes is an unsigned number, it wraps at the end of the loop allowing us to go back into loop and causing crash in memcpy. I used update function in digest.c to model this fix. Please let me know if it looks ok. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [CRYPTO] xcbc: Remove bogus hash/cipher testHerbert Xu2008-01-111-4/+1
| | | | | | | | | | When setting the digest size xcbc tests to see if the underlying algorithm is a hash. This is silly because we don't allow it to be a hash and we've specifically requested for a cipher. This patch removes the bogus test. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] xcbc: Fix algorithm leak when block size check failsHerbert Xu2008-01-111-1/+2
| | | | | | | | | | When the underlying algorithm has a block size other than 16 we abort without freeing it. In fact, we try to return the algorithm itself as an error! This patch plugs the leak and makes it return -EINVAL instead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [CRYPTO] templates: Pass type/mask when creating instancesHerbert Xu2007-05-021-3/+9
| | | | | | | | | | | | | This patch passes the type/mask along when constructing instances of templates. This is in preparation for templates that may support multiple types of instances depending on what is requested. For example, the planned software async crypto driver will use this construct. For the moment this allows us to check whether the instance constructed is of the correct type and avoid returning success if the type does not match.

* [CRYPTO] all: Check for usage in hard IRQ contextHerbert Xu2007-02-071-4/+17
| | | | | | | | | | Using blkcipher/hash crypto operations in hard IRQ context can lead to random memory corruption due to the reuse of kmap_atomic slots. Since crypto operations were never meant to be used in hard IRQ contexts, this patch checks for such usage and returns an error before kmap_atomic is performed.
