  • a0118c8b2   crypto: caam - fix non-hmac hashes ... Browse Code »

    Since 6de62f15b581 ("crypto: algif_hash - Require setkey before
    accept(2)"), the AF_ALG interface requires userspace to provide a key
    to any algorithm that has a setkey method. However, the non-HMAC
    algorithms are not keyed, so setting a key is unnecessary.

    Fix this by removing the setkey method from the non-keyed hash
    algorithms.

    To be able to generate shared descriptors for AEAD, the authentication size
    needs to be known. However, there is no imposed order of calling .setkey,
    .setauthsize callbacks.

    Thus, in case authentication size is not known at .setkey time, defer it
    until .setauthsize is called.

    The authsize != 0 check was incorrectly removed when converting the driver
    to the new AEAD interface.

  • 1d2d87e81   crypto: caam - fix echainiv(authenc) encrypt shared descriptor ... Browse Code »

    There are a few things missed by the conversion to the
    new AEAD interface:

    1 - echainiv(authenc) encrypt shared descriptor

    The shared descriptor is incorrect: due to the order of operations,
    at some point in time MATH3 register is being overwritten.

    2 - buffer used for echainiv(authenc) encrypt shared descriptor

    Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually
    exclusive and thus use the same buffer in context state: sh_desc_enc.

    However, there's one place missed by s/sh_desc_givenc/sh_desc_enc,
    leading to errors when echainiv(authenc(...)) algorithms are used:
    DECO: desc idx 14: Header Error. Invalid length or parity, or
    certain other problems.

    While here, also fix a typo: dma_mapping_error() is checking
    for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

    The IV output vectors should only be copied from the _complete operation
    and not from the _process operation, i.e only from the operation that is
    designed to copy the result of the request to the right location. This
    copy is already done in the _complete operation, so this commit removes

    So far, the cache of the ahash requests was updated from the 'complete'
    operation. This complete operation is called from mv_cesa_tdma_process
    before the cleanup operation, which means that the content of req->src
    can be read and copied when it is still mapped. This commit fixes the
    issue by moving this cache update from mv_cesa_ahash_complete to
    mv_cesa_ahash_req_cleanup, so the copy is done once the sglist is
    unmapped.

    Pull s390 updates from Martin Schwidefsky:
    "There are a couple of new things for s390 with this merge request:

    - a new scheduling domain "drawer" is added to reflect the unusual
    topology found on z13 machines. Performance tests showed up to 8
    percent gain with the additional domain.

    - the new crc-32 checksum crypto module uses the vector-galois-field
    multiply and sum SIMD instruction to speed up crc-32 and crc-32c.

    - proper __ro_after_init support, this requires RO_AFTER_INIT_DATA in
    the generic vmlinux.lds linker script definitions.

    - kcov instrumentation support. A prerequisite for that is the
    inline assembly basic block cleanup, which is the reason for the
    net/iucv/iucv.c change.

    - support for 2GB pages is added to the hugetlbfs backend.

    Then there are two removals:

    - the oprofile hardware sampling support is dead code and is removed.
    The oprofile user space uses the perf interface nowadays.

    - the ETR clock synchronization is removed, this has been superseeded
    be the STP clock synchronization. And it always has been

  • 9ac1c3200   crypto: ux500 - do not build with -O0 ... Browse Code »

    The ARM allmodconfig build currently warngs because of the
    ux500 crypto driver not working well with the jump label
    implementation that we started using for dynamic debug, which
    breaks building with 'gcc -O0':

    asm_volatile_goto("1:\n\t"

    Turning off compiler optimizations has never really been supported
    here, and it's only used when debugging the driver. I have not found
    a good reason for doing this here, other than a misguided attempt
    to produce more readable assembly output. Also, the driver is only
    used in obsolete hardware that almost certainly nobody will spend
    time debugging any more.

    This just removes the -O0 flag from the compiler options.

  • 85e0687f8   crypto: omap-sham - set sw fallback to 240 bytes ... Browse Code »

    Adds software fallback support for small crypto requests. In these cases,
    it is undesirable to use DMA, as setting it up itself is rather heavy
    operation. Gives about 40% extra performance in ipsec usecase.

    The extra call to dmaengine_terminate_all is not needed, as the DMA
    is not running at this point. This improves performance slightly.

    Change crypto queue size from 1 to 10 for omap SHA driver. This should
    allow clients to enqueue requests more effectively to avoid serializing
    whole crypto sequences, giving extra performance.

  • e93f767be   crypto: omap-sham - use runtime_pm autosuspend for clock handling ... Browse Code »

    Calling runtime PM API for every block causes serious performance hit to
    crypto operations that are done on a long buffer. As crypto is performed
    on a page boundary, encrypting large buffers can cause a series of crypto
    operations divided by page. The runtime PM API is also called those many
    times.

    Convert the driver to use runtime_pm autosuspend instead, with a default
    timeout value of 1 second. This results in upto ~50% speedup.

  • 47a1f0b2d   crypto: marvell - Increase the size of the crypto queue ... Browse Code »

    Now that crypto requests are chained together at the DMA level, we
    increase the size of the crypto queue for each engine. The result is
    that as the backlog list is reached later, it does not stop the crypto
    stack from sending asychronous requests, so more cryptographic tasks
    are processed by the engines.
