  • e61c0e336   [PATCH] dell_rbu: enhancements and fixes ... Browse Code »

    BUG fixes:

    The driver used to allocate memory with spinlock held which has been
    fixed in this patch.

    The driver was printing the entire buffer when it received a invalid
    entry in image_type. The fix is to only print a warning message and not
    the buffer.

    Usability enhancements:

    It is possible that due to user error the /sys/class/firmware/dell_rbu
    entries might be missing, this can happen if the user does the following

    echo 1 > /sys/class/firmware/dell_rbu/loading
    echo 0 > /sys/class/firmware/dell_rbu/loading

    This will make the entries in /sys/class/firmware/ to disappear and the
    only way get them back was bby unloading and loading the driver.

    This patch makes the user recreate these entries by echoing init in to
    image_type.

    This patch has been tested with Libsmbios and Dell OpenManage.

  • 7672d0b54   [NET]: Add netlink connector. ... Browse Code »

    Kernel connector - new userspace kernel space easy to use
    communication module which implements easy to use bidirectional
    message bus using netlink as it's backend. Connector was created to
    eliminate complex skb handling both in send and receive message bus
    direction.

    Connector driver adds possibility to connect various agents using as
    one of it's backends netlink based network. One must register
    callback and identifier. When driver receives special netlink message
    with appropriate identifier, appropriate callback will be called.

    From the userspace point of view it's quite straightforward:

    socket();
    bind();
    send();
    recv();

    But if kernelspace want to use full power of such connections, driver
    writer must create special sockets, must know about struct sk_buff
    handling... Connector allows any kernelspace agents to use netlink
    based networking for inter-process communication in a significantly
    easier way:

    int cn_add_callback(struct cb_id *id, char *name, void (*callback) (void *));
    void cn_netlink_send(struct cn_msg *msg, u32 __groups, int gfp_mask);

    struct cb_id
    {
    __u32 idx;
    __u32 val;
    };

    idx and val are unique identifiers which must be registered in
    connector.h for in-kernel usage. void (*callback) (void *) - is a
    callback function which will be called when message with above idx.val
    will be received by connector core.

    Using connector completely hides low-level transport layer from it's
    users.

    Connector uses new netlink ability to have many groups in one socket.

  • 5bb782690   kbuild: rename prepare to archprepare to fix dependency chain ... Browse Code »

    When introducing the generic asm-offsets.h support the dependency
    chain for the prepare targets was changed. All build scripts expecting
    include/asm/asm-offsets.h to be made when using the prepare target would broke.
    With the limited number of prepare targets left in arch Makefiles
    the trivial solution was to introduce a new arch specific target: archprepare

    The dependency chain looks like this now:

    prepare
    |
    +--> prepare0
    |
    +--> archprepare
    |
    +--> scripts_basic
    +--> prepare1
    |
    +---> prepare2
    |
    +--> prepare3

    So prepare 3 is processed before prepare2 etc.
    This guaantees that the asm symlink, version.h, scripts_basic
    are all updated before archprepare is processed.

    prepare0 which build the asm-offsets.h file will need the
    actions performed by archprepare.

    The head target is now named prepare, because users scripts will most
    likely use that target, but prepare-all has been kept for compatibility.
    Updated Documentation/kbuild/makefiles.txt.
