  • 76fafbfff   w1: Replace zero-length array with flexible-array ... Browse Code »

    There is a regular need in the kernel to provide a way to declare having a
    dynamically sized set of trailing elements in a structure. Kernel code should
    always use “flexible array members”[1] for these cases. The older style of
    one-element or zero-length arrays should no longer be used[2].

  • de0d6dbdb   w1: Add subsystem kernel public interface ... Browse Code »

    Like other subsystems we should be able to define slave devices outside
    of the w1 directory. To do this we move public facing interface
    definitions to include/linux/w1.h and rename the internal definition
    file to w1_internal.h.

    As w1_family.h and w1_int.h contained almost entirely public
    driver interface definitions we simply removed these files and
    moved the remaining definitions into w1_internal.h.

    With this we can now start to move slave devices out of w1/slaves and
    into the subsystem based on the function they implement, again like
    other drivers.

    Remove filename from file, this is not done anymore as it doesn't
    add anything and usually is incorrect as filename change often.

    Also shorten the GPL to the more common address-less version and
    remove excess white-space.

  • 8a0427d19   w1: optional bundling of netlink kernel replies ... Browse Code »

    Applications can submit a set of commands in one packet to the kernel,
    and in some cases it is required such as reading the temperature
    sensor results. This adds an option W1_CN_BUNDLE to the flags of
    cn_msg to request the kernel to reply in one packet for efficiency.

    The cn_msg flags now check for unknown flag values and return an error
    if one is seen. See "Proper handling of unknown flags in system
    calls" http://lwn.net/Articles/588444/

    This corrects the ack values returned as per the protocol standard,
    namely the original ack for status messages and seq + 1 for all others
    such as the data returned from a read.

    Some of the common variable names have been standardized as follows.
    struct cn_msg *cn
    struct w1_netlink_msg *msg
    struct w1_netlink_cmd *cmd
    struct w1_master *dev

    When an argument and a function scope variable would collide, add req_
    to the argument.

  • 70b34d2ed   w1: new netlink commands, add/remove/list slaves ... Browse Code »

    Introduce new commands to add, remove, and list slave devices through
    the netlink interface. This can be useful to skip the search on a
    static network. They could previously only be added or removed
    through automatic search or sysfs, and this allows a program to only
    use netlink.

    Only allocate memory when needed, so move kzalloc into w1_get_slaves
    where it was used.

    This patch series introduces and extends several userspace commands
    used with netlink protocol.

    Touch block command allows to write data and return sampled data to
    the userspace.

    Extended search and alarm seach commands to return list of slave
    devices found during given search.

    List masters command allows to send all registered master IDs to the
    userspace.

    Great thanks to Paul Alfille (owfs) who
    tested this implementation and wrote w1-to-network daemon
    http://sourceforge.net/projects/w1repeater/ and

    Frederik Deweerdt and Randy Dunlap for review.

    This patch:

    Returns list of registered bus master devices.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
