2019-06-13crypto: make all generic algorithms set cra_driver_nameEric Biggers1-3/+4
Most generic crypto algorithms declare a driver name ending in "-generic". The rest don't declare a driver name and instead rely on the crypto API automagically appending "-generic" upon registration. Having multiple conventions is unnecessarily confusing and makes it harder to grep for all generic algorithms in the kernel source tree. But also, allowing NULL driver names is problematic because sometimes people fail to set it, e.g. the case fixed by commit 417980364300 ("crypto: cavium/zip - fix collision with generic cra_driver_name"). Of course, people can also incorrectly name their drivers "-generic". But that's much easier to notice / grep for. Therefore, let's make cra_driver_name mandatory. In preparation for this, this patch makes all generic algorithms set cra_driver_name. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-04-18crypto: run initcalls for generic implementations earlierEric Biggers1-1/+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.

2018-07-09crypto: shash - remove useless setting of type flagsEric Biggers1-1/+0
Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH. But this is redundant with the C structure type ('struct shash_alg'), and crypto_register_shash() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the shash algorithms. This patch shouldn't change any actual behavior.

2018-03-31crypto: Deduplicate le32_to_cpu_array() and cpu_to_le32_array()Andy Shevchenko1-17/+0
Deduplicate le32_to_cpu_array() and cpu_to_le32_array() by moving them to the generic header. No functional change implied. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2014-11-24crypto: prefix module autoloading with "crypto-"Kees Cook1-1/+1
This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2011-10-31crypto: add module.h to those files that are explicitly using itPaul Gortmaker1-0/+1
Part of the include cleanups means that the implicit inclusion of module.h via device.h is going away. So fix things up in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2008-12-25crypto: md4 - Use ARRAY_SIZEJulia Lawall1-2/+2
ARRAY_SIZE is more concise to use when the size of an array is divided by the size of its type or the size of its first element. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @i@ @@ #include <linux/kernel.h> @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(T)) + ARRAY_SIZE(E) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Thanks for the suggestion, the init() is replaced with <algorithm name>_mod_init () and fini () is replaced with <algorithm name>_mod_fini.

2006-06-26[CRYPTO] all: Pass tfm instead of ctx to algorithmsHerbert Xu1-6/+6
Up until now algorithms have been happy to get a context pointer since they know everything that's in the tfm already (e.g., alignment, block size). However, once we have parameterised algorithms, such information will be specific to each tfm. So the algorithm API needs to be changed to pass the tfm structure instead of the context pointer. This patch is basically a text substitution. The only tricky bit is the assembly routines that need to get the context pointer offset through asm-offsets.h.

2006-01-09[CRYPTO] Use standard byte order macros wherever possibleHerbert Xu1-0/+1
A lot of crypto code needs to read/write a 32-bit/64-bit words in a specific gender. Many of them open code them by reading/writing one byte at a time. This patch converts all the applicable usages over to use the standard byte order macros. This is based on a previous patch by Denis Vlasenko. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+250
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
