crypto: make all generic algorithms set cra_driver_name

2019-06-13T06:31:39+00:00

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.

crypto: run initcalls for generic implementations earlier

2019-04-18T14:15:03+00:00

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: prefix module autoloading with "crypto-"

2014-11-24T14:43:57+00:00

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:

[PATCH] Update my email address from jkmaline@cc.hut.fi to j@w1.fi

2007-04-28T15:01:01+00:00

After 13 years of use, it looks like my email address is finally going
to disappear. While this is likely to drop the amount of incoming spam
greatly ;-), it may also affect more appropriate messages, so let's
update my email address in various places. In addition, Host AP mailing
list is subscribers-only and linux-wireless can also be used for
discussing issues related to this driver which is now shown in
MAINTAINERS.

[CRYPTO] api: Get rid of flags argument to setkey

2006-09-21T01:41:02+00:00

Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &tfm->crt_flags pointer.

This patch also gets rid of a few unnecessary checks on the key length
for ciphers as the cipher layer guarantees that the key length is within
the bounds specified by the algorithm.

Rather than testing dia_setkey every time, this patch does it only once
during crypto_alloc_tfm.  The redundant check from crypto_digest_setkey
is also removed.

[CRYPTO] all: Pass tfm instead of ctx to algorithms

2006-06-26T07:34:39+00:00

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.

[CRYPTO] digest: Add alignment handling

2006-06-26T07:34:38+00:00

Some hash modules load/store data words directly.  The digest layer
should pass properly aligned buffer to update()/final() method.  This
patch also add cra_alignmask to some hash modules.
