  • ad6ce87e5   [PATCH] dell_rbu: changes in packet update mechanism ... Browse Code »

    In the current dell_rbu code ver 2.0 the packet update mechanism makes the
    user app dump every individual packet in to the driver.

    This adds in efficiency as every packet update makes the
    /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear
    again. Thus the user app needs to wait for the files to reappear to dump
    another packet. This slows down the packet update tremendously in case of
    large number of packets. I am submitting a new patch for dell_rbu which will
    change the way we do packet updates;

    In the new method the user app will create a new single file which has already
    packetized the rbu image and all the packets are now staged in this file.

    This driver also creates a new entry in
    /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet
    size here before downloading the packet file.

    The user should do the following:

    create one single file which has all the packets stacked together.
    echo the packet size in to /sys/devices/platform/dell_rbu/packet_size.
    echo 1 > /sys/class/firmware/dell_rbu/loading
    cat the packetfile > /sys/class/firmware/dell_rbu/data
    echo 0 > /sys/class/firmware/dell_rbu/loading

    The driver takes the file which came through /sys/class/firmware/dell_rbu/data
    and takes chunks of paket_size data from it and place in contiguous memory.

    This makes packet update process very efficient and fast. As all the packet
    update happens in one single operation. The user can still read back the
    downloaded file from /sys/devices/platform/dell_rbu/data.

  • 664cceb00   [PATCH] Keys: Add possessor permissions to keys [try #3] ... Browse Code »

    The attached patch adds extra permission grants to keys for the possessor of a
    key in addition to the owner, group and other permissions bits. This makes
    SUID binaries easier to support without going as far as labelling keys and key
    targets using the LSM facilities.

    This patch adds a second "pointer type" to key structures (struct key_ref *)
    that can have the bottom bit of the address set to indicate the possession of
    a key. This is propagated through searches from the keyring to the discovered
    key. It has been made a separate type so that the compiler can spot attempts
    to dereference a potentially incorrect pointer.

    The "possession" attribute can't be attached to a key structure directly as
    it's not an intrinsic property of a key.

    Pointers to keys have been replaced with struct key_ref *'s wherever
    possession information needs to be passed through.

    This does assume that the bottom bit of the pointer will always be zero on
    return from kmem_cache_alloc().

    The key reference type has been made into a typedef so that at least it can be
    located in the sources, even though it's basically a pointer to an undefined
    type. I've also renamed the accessor functions to be more useful, and all
    reference variables should now end in "_ref".

  • 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.
