crypto: testmgr - skip crc32c context test for ahash algorithms

2019-07-09T21:03:52+00:00

commit eb5e6730db98fcc4b51148b4a819fa4bf864ae54 upstream.

Instantiating "cryptd(crc32c)" causes a crypto self-test failure because
the crypto_alloc_shash() in alg_test_crc32c() fails.  This is because
cryptd(crc32c) is an ahash algorithm, not a shash algorithm; so it can
only be accessed through the ahash API, unlike shash algorithms which
can be accessed through both the ahash and shash APIs.

As the test is testing the shash descriptor format which is only
applicable to shash algorithms, skip it for ahash algorithms.

(Note that it's still important to fix crypto self-test failures even
 for weird algorithm instantiations like cryptd(crc32c) that no one
 would really use; in fips_enabled mode unprivileged users can use them
 to panic the kernel, and also they prevent treating a crypto self-test
 failure as a bug when fuzzing the kernel.)

crypto: testmgr - add aead cbc des, des3_ede tests

2014-05-22T13:03:18+00:00

Test vectors were taken from existing test for
CBC(DES3_EDE). Associated data has been added to test vectors.
HMAC computed with Crypto++ has been used. Following algos have
been covered.

        (a) "authenc(hmac(sha1),cbc(des))"
        (b) "authenc(hmac(sha1),cbc(des3_ede))"
        (c) "authenc(hmac(sha224),cbc(des))"
        (d) "authenc(hmac(sha224),cbc(des3_ede))"
        (e) "authenc(hmac(sha256),cbc(des))"
        (f) "authenc(hmac(sha256),cbc(des3_ede))"
        (g) "authenc(hmac(sha384),cbc(des))"
        (h) "authenc(hmac(sha384),cbc(des3_ede))"
        (i) "authenc(hmac(sha512),cbc(des))"
        (j) "authenc(hmac(sha512),cbc(des3_ede))"

crypto: testmgr - fix sglen in test_aead for case 'dst != src'

2013-11-28T14:25:17+00:00

Commit d8a32ac25698cd60b02bed2100379803c7f964e3 (crypto: testmgr - make
test_aead also test 'dst != src' code paths) added support for different
source and destination buffers in test_aead.

This patch modifies the source and destination buffer lengths accordingly:
the lengths are not equal since encryption / decryption adds / removes
the ICV.

Use this new function to make code more comprehensible, since we are

Now that module softdeps are in the kernel we can use that to resolve
the boot issue which cause the revert.

Unfortunately this change broke boot on some systems that used an
initrd which does not include the newly created crct10dif modules.
As these modules are required by sd_mod under certain configurations
this is a serious problem.
