  • e25df7812   misc: ibmvsm: Fix potential NULL pointer dereference ... Browse Code »

    There is a potential NULL pointer dereference in case kzalloc()
    fails and returns NULL.

    Fix this by adding a NULL check on *session*

    Also, update the function header with information about the
    expected return on failure and remove unnecessary variable rc.

    This issue was detected with the help of Coccinelle.

    The function alloc_dma_buffer() is called from ibmvmc_add_buffer(),
    in which a spin lock be held here, so we should use GFP_ATOMIC when
    a lock is held.

    This driver is a logical device which provides an
    interface between the hypervisor and a management
    partition. This interface is like a message
    passing interface. This management partition
    is intended to provide an alternative to HMC-based
    system management.

    VMC enables the Management LPAR to provide basic
    logical partition functions:
    - Logical Partition Configuration
    - Boot, start, and stop actions for individual
    partitions
    - Display of partition status
    - Management of virtual Ethernet
    - Management of virtual Storage
    - Basic system management

    This driver is to be used for the POWER Virtual
    Management Channel Virtual Adapter on the PowerPC
    platform. It provides a character device which
    allows for both request/response and async message
    support through the /dev/ibmvmc node.
