[PATCH 0/6] crypto: module alias fixes

[Mathias Krause]

Hi Herbert,

this series is a follow up to commit 5d26a105b5a7 ("crypto: prefix
module autoloading with "crypto-""). In patch 1 it adds the required
MODULE_ALIAS_CRYPTO annotation where needed to bring back automatic
crypto module loading. Namely, modules that have a file name matching
the cipher they implement still need the MODULE_ALIAS_CRYPTO()
annotation. Otherwise they won't get loaded.

Patches 2 to 6 fix bogus module descriptions or aliases with the
exception of patch 4 which adds a missing crypto module alias.

At least patch 1 should go to crypto-2.6 to not regress the crypto API
for v3.19 in regard to automatic module loading.

The others are probably safe to apply, too.

Please apply!

Thanks,

[PATCH 1/6] crypto: add missing crypto module aliases

[Mathias Krause]

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.

Fixes: 5d26a105b5a7 ("crypto: prefix module autoloading with "crypto-"")

[PATCH 4/6] crypto: sparc64/des - add "des3_ede" module alias

[Mathias Krause]

This module provides implementations for "des3_ede", too. Announce those
via an appropriate crypto module alias so it can be used in favour to
the generic C implementation.
