  • 3c97ce1f8   Bluetooth: a2mp: Use struct_size() helper ... Browse Code »

    One of the more common cases of allocation size calculations is finding
    the size of a structure that has a zero-sized array at the end, along
    with memory for some number of elements for that array. For example:

    struct foo {
    int stuff;
    struct boo entry[];
    };

    size = sizeof(struct foo) + count * sizeof(struct boo);
    instance = alloc(size, GFP_KERNEL)

    Instead of leaving these open-coded and prone to type mistakes, we can
    now use the new struct_size() helper:

    size = struct_size(instance, entry, count);
    instance = alloc(size, GFP_KERNEL)

    This code was detected with the help of Coccinelle.

  • aa563d7bc   iov_iter: Separate type from direction and use accessor functions ... Browse Code »

    In the iov_iter struct, separate the iterator type from the iterator
    direction and use accessor functions to access them in most places.

    Convert a bunch of places to use switch-statements to access them rather
    then chains of bitwise-AND statements. This makes it easier to add further
    iterator types. Also, this can be more efficient as to implement a switch
    of small contiguous integers, the compiler can use ~50% fewer compare
    instructions than it has to use bitwise-and instructions.

    Further, cease passing the iterator type into the iterator setup function.
    The iterator function can set that itself. Only the direction is required.

  • af72868b9   networking: make skb_pull & friends return void pointers ... Browse Code »

    It seems like a historic accident that these return unsigned char *,
    and in many places that means casts are required, more often than not.

    Make these functions return void * and remove all the casts across
    the tree, adding a (u8 *) cast only where the unsigned char pointer
    was used directly, all done with the following spatch:

    @@
    expression SKB, LEN;
    typedef u8;
    identifier fn = {
    skb_pull,
    __skb_pull,
    skb_pull_inline,

    __pskb_pull,
    pskb_pull
    };

  • 2c935bc57   locking/atomic, kref: Add kref_read() ... Browse Code »

    Since we need to change the implementation, stop exposing internals.

    Provide kref_read() to read the current reference count; typically
    used for debug messages.

    Kills two anti-patterns:

    atomic_read(&kref->refcount)
    kref->refcount.counter

  • 2338a7e04   Bluetooth: Rename L2CAP_CHAN_CONN_FIX_A2MP to L2CAP_CHAN_FIXED ... Browse Code »

    There's no reason why A2MP should need or deserve its on channel type.
    Instead we should be able to group all fixed CID users under a single
    channel type and reuse as much code as possible for them. Where CID
    specific exceptions are needed the chan-scid value can be used.

    This patch renames the current A2MP channel type to a generic one and
    thereby paves the way to allow converting ATT and SMP (and any future
    fixed channel protocols) to use the new channel type.

    We need to remove all direct access of struct sock from L2CAP core.
    This change is pretty simple and just add a new L2CAP channel callback to
    do the work in the L2CAP socket side.

  • 8d836d71e   Bluetooth: Access sk_sndtimeo indirectly in l2cap_core.c ... Browse Code »

    As part of the work to remove struct sock from l2cap_core.c and make it
    more generic we remove in this commit the direct access to sk->sk_sndtimeo
    member. This objective of this change is purely remove sk usage from
    l2cap_core.c

    Now we have a new l2cap ops to get the current value of sk->sndtimeo. A
    l2cap_chan_no_get_sndtimeo was added for users of L2CAP that doesn't need
    to set a timeout.

  • 53f521212   Bluetooth: Extend state_change() call to report errors too ... Browse Code »

    Instead of creating an new function pointer to report errors we are just
    reusing state_change for that and there is a simple reason for this, one
    place in the l2cap_core.c code needs, in a locked sk, set both the sk_state
    and sk_err. If we create two different functions for this we would need to
    release the lock between the two operation putting the socket in non
    desired state.

    The change is transparent to the l2cap_core.c code, user that only needs
    to set the state won't need any modification.

    This is another step of an ongoing work to make l2cap_core.c totally
    independent from l2cap's struct sock.
