• c4741b230   crypto: run initcalls for generic implementations earlier ... Browse Code »

  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.

• 1af39daaa   crypto: replace FSF address with web source in license notices ... Browse Code »

  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 "".

• 3e14dcf7c   crypto: add missing crypto module aliases ... Browse Code »

  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.

  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:

  Rename cast5 module to cast5_generic to allow autoloading of optimized
  implementations. Generic functions and s-boxes are exported to be able to use
  them within optimized implementations.
