  • d6ebf5286   crypto: make all generic algorithms set cra_driver_name ... Browse Code »

    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.

  • c4741b230   crypto: run initcalls for generic implementations earlier ... Browse Code »

    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.

    There are many code paths opencoding kvmalloc. Let's use the helper
    instead. The main difference to kvmalloc is that those users are
    usually not considering all the aspects of the memory allocator. E.g.

    __GFP_REPEAT has a rather weak semantic but since it has been introduced
    around 2.6.12 it has been ignored for low order allocations.

    lzo_init uses __GFP_REPEAT to allocate LZO1X_MEM_COMPRESS 16K. This is
    order 3 allocation request and __GFP_REPEAT is ignored for this size

  • 42614b058   crypto: lzo - try kmalloc() before vmalloc() ... Browse Code »

    zswap allocates one LZO context per online cpu.

    Using vmalloc() for small (16KB) memory areas has drawback of slowing
    down /proc/vmallocinfo and /proc/meminfo reads, TLB pressure and poor
    NUMA locality, as default NUMA policy at boot time is to interleave
    pages :

    edumazet:~# grep lzo /proc/vmallocinfo | head -4
    0xffffc90006062000-0xffffc90006067000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2
    0xffffc90006067000-0xffffc9000606c000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2
    0xffffc9000606c000-0xffffc90006071000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2
    0xffffc90006071000-0xffffc90006076000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2

    This patch tries a regular kmalloc() and fallback to vmalloc in case
    memory is too fragmented.

    Initialization of cra_list is currently mixed, most ciphers initialize this
    field and most shashes do not. Initialization however is not needed at all
    since cra_list is initialized/overwritten in __crypto_register_alg() with
    list_add(). Therefore perform cleanup to remove all unneeded initializations
    of this field in 'crypto/'.

    Thanks for the suggestion, the init() is replaced with

    _mod_init ()

    and fini () is replaced with _mod_fini.
