2018-11-20crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm allocationsEric Biggers
'cipher' algorithms (single block ciphers) are always synchronous, so passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no effect. Many users therefore already don't pass it, but some still do. This inconsistency can cause confusion, especially since the way the 'mask' argument works is somewhat counterintuitive. Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags. This patch shouldn't change any actual behavior.

2013-01-03Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/drivers/'.

2008-01-11[CRYPTO] geode: relax in busy loop and care about return valueSebastian Siewior
The code waits in a busy loop until the hardware finishes the encryption or decryption process. This wants a cpu_relax() :) The busy loop finishes either if the encryption is done or if the counter is zero. If the latter is true than the hardware failed.

2008-01-11[CRYPTO] geode: use consistent IV copySebastian Siewior
It is enough if the IV is copied before and after the while loop. With DM-Crypt is seems not be required to save the IV after encrytion because a new one is used in the request (dunno about other users). It is not save to load the IV within while loop and not save afterwards because we mill end up with the wrong IV if the request goes consists of more than one page.

2007-11-11[CRYPTO] geode: Fix not inplace encryptionSebastian Siewior

2007-10-10[CRYPTO] aes: Rename aes to aes-genericSebastian Siewior
Loading the crypto algorithm by the alias instead of by module directly has the advantage that all possible implementations of this algorithm are loaded automatically and the crypto API can choose the best one depending on its priority. Additionally it ensures that the generic implementation as well as the HW driver (if available) is loaded in case the HW driver needs the generic version as fallback in corner cases.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
