  • We leak in drivers/scsi/aacraid/commctrl.c::aac_send_raw_srb() :

    We allocate memory:

    ...
    struct user_sgmap* usg;
    usg = kmalloc(actual_fibsize - sizeof(struct aac_srb)
    + sizeof(struct sgmap), GFP_KERNEL);

    and then neglect to free it:

    ...
    for (i = 0; i < usg->count; i++) {
    u64 addr;
    void* p;
    if (usg->sg[i].count >
    ((dev->adapter_info.options &
    AAC_OPT_NEW_COMM) ?
    (dev->scsi_host_ptr->max_sectors << 9) :
    65536)) {
    rcode = -EINVAL;
    goto cleanup;
    ... this 'goto' makes 'usg' go out of scope and leak the memory we
    allocated.

    Other exits properly kfree(usg), it's just here it is neglected.

  • md update for 3.3

    Big change is new hot-replacement.
    A slot in an array can hold 2 devices - one that
    wants-replacement and one that is the replacement.
    Once the replacement is built - either from the
    original or (in the case of errors) from elsewhere,
    the wants-replacement device will be removed.

  • This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
    and it fixes the build error in the arch/x86/kernel/microcode_core.c
    file, that the merge did not catch.

    The microcode_core.c patch was provided by Stephen Rothwell
    who was invaluable in the merge issues involved
    with the large sysdev removal process in the driver-core tree.

  • Mark dma-buf buffer sharing API as EXPERIMENTAL for first release.
    We will remove this in later versions, once it gets smoothed out
    and has more users.

  • This is the first step in defining a dma buffer sharing mechanism.

    A new buffer object dma_buf is added, with operations and API to allow easy
    sharing of this buffer object across devices.

    The framework allows:
    - creation of a buffer object, its association with a file pointer, and
    associated allocator-defined operations on that buffer. This operation is
    called the 'export' operation.
    - different devices to 'attach' themselves to this exported buffer object, to
    facilitate backing storage negotiation, using dma_buf_attach() API.
    - the exported buffer object to be shared with the other entity by asking for
    its 'file-descriptor (fd)', and sharing the fd across.
    - a received fd to get the buffer object back, where it can be accessed using
    the associated exporter-defined operations.
    - the exporter and user to share the scatterlist associated with this buffer
    object using map_dma_buf and unmap_dma_buf operations.

    Atleast one 'attach()' call is required to be made prior to calling the
    map_dma_buf() operation.

    Couple of building blocks in map_dma_buf() are added to ease introduction
    of sync'ing across exporter and users, and late allocation by the exporter.

    For this first version, this framework will work with certain conditions:
    - *ONLY* exporter will be allowed to mmap to userspace (outside of this
    framework - mmap is not a buffer object operation),
    - currently, *ONLY* users that do not need CPU access to the buffer are
    allowed.

    More details are there in the documentation patch.

    This is based on design suggestions from many people at the mini-summits[1],
    most notably from Arnd Bergmann , Rob Clark and
    Daniel Vetter .

    The implementation is inspired from proof-of-concept patch-set from
    Tomasz Stanislawski , who demonstrated buffer sharing
    between two v4l2 devices. [2]

  • When a bnx2x device encounters parity errors, it will not respond to all
    SPQ messages. As a result, the shutdown sequence before reset can take
    a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
    of all such messages.

    To improve this scenario, when bnx2x returns error on the SPQ, we'll send
    an immediate response to the ulp drivers to avoid such lengthy timeouts.

    Adjust the return code of relevant functions to return error only if
    the message cannot be sent on the SPQ so that we'll generate an error
    completion to the ulp drivers.
