| * crypto: make all generic algorithms set cra_driver_nameEric Biggers2019-06-131-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* 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: shash - remove useless setting of type flagsEric Biggers2018-07-091-3/+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.

* crypto: add missing crypto module aliasesMathias Krause2015-01-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | Commit 5d26a105b5a7 ("crypto: prefix module autoloading with "crypto-"") changed the automatic module loading when requesting crypto algorithms to prefix all module requests with "crypto-". This requires all crypto modules to have a crypto specific module alias even if their file name would otherwise match the requested crypto algorithm. Even though commit 5d26a105b5a7 added those aliases for a vast amount of modules, it was missing a few. Add the required MODULE_ALIAS_CRYPTO annotations to those files to make them get loaded automatically, again. This fixes, e.g., requesting 'ecb(blowfish-generic)', which used to work with kernels v3.18 and below. Also change MODULE_ALIAS() lines to MODULE_ALIAS_CRYPTO(). The former won't work for crypto modules any more.

* crypto: memzero_explicit - make sure to clear out sensitive dataDaniel Borkmann2014-10-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently, in commit 13aa93c70e71 ("random: add and use memzero_explicit() for clearing data"), we have found that GCC may optimize some memset() cases away when it detects a stack variable is not being used anymore and going out of scope. This can happen, for example, in cases when we are clearing out sensitive information such as keying material or any e.g. intermediate results from crypto computations, etc. With the help of Coccinelle, we can figure out and fix such occurences in the crypto subsytem as well. Julia Lawall provided the following Coccinelle program: @@ type T; identifier x; @@ T x; ... when exists when any -memset +memzero_explicit (&x, -0, ...) ... when != x when strict @@ type T; identifier x; @@ T x[...]; ... when exists when any -memset +memzero_explicit (x, -0, ...) ... when != x when strict Therefore, make use of the drop-in replacement memzero_explicit() for exactly such cases instead of using memset().

* [CRYPTO] all: Pass tfm instead of ctx to algorithmsHerbert Xu2006-06-261-15/+14
| | | | | | | | | | | | | | | | 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.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+735
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!
