  • 66e5bd006   crypto: testmgr - add test vector for fcrypt ... Browse Code »

    fcrypt is used only as pcbc(fcrypt), but testmgr does not know this.
    Use the zero key, zero plaintext pcbc(fcrypt) test vector for
    testing plain 'fcrypt' to hide "no test for fcrypt" warnings.

    This patch adds AES-NI/AVX/x86_64 assembler implementation of Camellia block
    cipher. Implementation process data in sixteen block chunks, which are
    byte-sliced and AES SubBytes is reused for Camellia s-box with help of pre-
    and post-filtering.

    Patch has been tested with tcrypt and automated filesystem tests.

    tcrypt test results:

    This patch adds a x86_64/avx assembler implementation of the Cast6 block
    cipher. The implementation processes eight blocks in parallel (two 4 block
    chunk AVX operations). The table-lookups are done in general-purpose registers.
    For small blocksizes the functions from the generic module are called. A good
    performance increase is provided for blocksizes greater or equal to 128B.

    Patch has been tested with tcrypt and automated filesystem tests.

    Patch 863b557a88f8c033f7419fabafef4712a5055f85 added NULL entries
    for intel accelerated drivers but did not marked these fips allowed.
    This cause panic if running tests with fips=1.

    For ghash, fips_allowed flag was added in patch
    18c0ebd2d8194cce4b3f67e2903fa01bea892cbc.

    Without patch, "modprobe tcrypt" fails with

    null tests above, otherwise system complains with

    This patch adds a x86_64/avx assembler implementation of the Serpent block
    cipher. The implementation is very similar to the sse2 implementation and
    processes eight blocks in parallel. Because of the new non-destructive three
    operand syntax all move-instructions can be removed and therefore a little
    performance increase is provided.

    Patch has been tested with tcrypt and automated filesystem tests.

    Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler
    functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations
    in parallel to improve performance on out-of-order CPUs). Glue code is based
    on one from AES-NI implementation, so requests from irq context are redirected
    to cryptd.

    v2:
    - add missing include of linux/module.h
    (appearently crypto.h used to include module.h, which changed for 3.2 by
    commit 7c926402a7e8c9b279968fd94efec8700ba3859e)

    Patch has been tested with tcrypt and automated filesystem tests.

    A self-test failure in fips mode means a panic. Well, gcm(aes)
    self-tests currently fail in fips mode, as gcm is dependent on ghash,
    which semi-recently got self-test vectors added, but wasn't marked as a
    fips_allowed algorithm. Because of gcm's dependence on what is now seen
    as a non-fips_allowed algorithm, its self-tests refuse to run.
    Previously, ghash got a pass in fips mode, due to the lack of any test
    vectors at all, and thus gcm self-tests were able to run. After this
    patch, a 'modprobe tcrypt mode=35' no longer panics in fips mode, and
    successful self-test of gcm(aes) is reported.

    We (Red Hat) are intending to include dm-crypt functionality, using
    xts(aes) for disk encryption, as part of an upcoming FIPS-140-2
    certification effort, and xts(aes) *is* on the list of possible
    mode/cipher combinations that can be certified. To make that possible, we
    need to mark xts(aes) as fips_allowed in the crypto subsystem.

    A 'modprobe tcrypt mode=10' in fips mode shows xts(aes) self-tests
    passing successfully after this change.

    This patch fixes a serious bug in the test disabling patch where
    it can cause an spurious load of the cryptomgr module even when
    it's compiled in.

    It also negates the test disabling option so that its absence
    causes tests to be enabled.

    The Kconfig option is also now behind EMBEDDED.

  • 863b557a8   crypto: testmgr - Fix complain about lack test for internal used algorithm ... Browse Code »

    When load aesni-intel and ghash_clmulni-intel driver,kernel will complain no
    test for some internal used algorithm.
    The strange information as following:

    alg: No test for __aes-aesni (__driver-aes-aesni)
    alg: No test for __ecb-aes-aesni (__driver-ecb-aes-aesni)
    alg: No test for __cbc-aes-aesni (__driver-cbc-aes-aesni)
    alg: No test for __ecb-aes-aesni (cryptd(__driver-ecb-aes-aesni)
    alg: No test for __ghash (__ghash-pclmulqdqni)
    alg: No test for __ghash (cryptd(__ghash-pclmulqdqni))

    This patch add NULL test entries for these algorithm and driver.
