crypto: authencesn - Fix digest_null crash

2017-08-07T01:59:40+00:00

commit 41cdf7a45389e01991ee31e3301ed83cb3e3f7dc upstream.

When authencesn is used together with digest_null a crash will
occur on the decrypt path.  This is because normally we perform
a special setup to preserve the ESN, but this is skipped if there
is no authentication.  However, on the post-authentication path
it always expects the preservation to be in place, thus causing
a crash when digest_null is used.

This patch fixes this by also skipping the post-processing when
there is no authentication.

crypto: authencesn - Use skcipher

2016-07-18T09:35:39+00:00

This patch converts authencesn to use the new skcipher interface as
opposed to ablkcipher.

It also fixes a little bug where if a sync version of authencesn
is requested we may still end up using an async ahash.  This should
have no effect as none of the authencesn users can request for a
sync authencesn.

crypto: authenc - Consider ahash ASYNC bit

2016-07-01T15:45:02+00:00

As it is, if you get an async ahash with a sync skcipher you'll
end up with a sync authenc, which is wrong.

This patch fixes it by considering the ASYNC bit from ahash as
well.

It also fixes a little bug where if a sync version of authenc
is requested we may still end up using an async ahash.

Neither of them should have any effect as none of the authenc
users can request for a sync authenc.

crypto: authencesn - Fix breakage with new ESP code

2015-08-10T15:13:51+00:00

The ESP code has been updated to generate a completely linear
AD SG list.  This unfortunately broke authencesn which expects
the AD to be divided into at least three parts.

This patch fixes it to cope with the new format.  Later we will
fix it properly to accept arbitrary input and not rely on the
input being linear as part of the AEAD conversion.

crypto: authencesn - Use crypto_aead_set_reqsize helper

2015-05-13T02:31:38+00:00

This patch uses the crypto_aead_set_reqsize helper to avoid directly
touching the internals of aead.

crypto: authencesn - Include internal/aead.h

2015-05-13T02:31:26+00:00

All AEAD implementations must include internal/aead.h in order
to access required helpers.

crypto: include crypto- module prefix in template

2014-11-26T12:06:30+00:00

This adds the module loading prefix "crypto-" to the template lookup
as well.

For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly
includes the "crypto-" prefix at every level, correctly rejecting "vfat":

	net-pf-38
	algif-hash
	crypto-vfat(blowfish)
	crypto-vfat(blowfish)-all
	crypto-vfat

crypto: authencesn - Simplify key parsing

Use the common helper function crypto_authenc_extractkeys() for key
parsing.
