memory space for IPC. But most process don't use full memory

    BACKPORT: binder: add function to copy binder object from buffer

    When creating or tearing down a transaction, the binder driver
    examines objects in the buffer and takes appropriate action.
    To do this without needing to dereference pointers into the
    buffer, the local copies of the objects are needed. This patch
    introduces a function to validate and copy binder objects
    from the buffer to a local structure.

    BACKPORT: binder: add functions to copy to/from binder buffers

    Avoid vm_area when copying to or from binder buffers.
    Instead, new copy functions are added that copy from
    kernel space to binder buffer space. These use
    kmap_atomic() and kunmap_atomic() to create temporary
    mappings and then memcpy() is used to copy within
    that page.

    Also, kmap_atomic() / kunmap_atomic() use the appropriate
    cache flushing to support VIVT cache architectures.
    Allow binder to build if CPU_CACHE_VIVT is defined.

    Several uses of the new functions are added here. More
    to follow in subsequent patches.

    UPSTREAM: binder: create userspace-to-binder-buffer copy function

    The binder driver uses a vm_area to map the per-process

    now taking too much vmalloc space. This patch removes

    binder_alloc_copy_user_to_buffer() which uses kmap()
    and kunmap() to map each page, and uses copy_from_user()
    for copying to that page.

    binder: fix race that allows malicious free of live buffer

    commit 7bada55ab50697861eee6bb7d60b41e68a961a9c upstream.

    Malicious code can attempt to free buffers using the BC_FREE_BUFFER
    ioctl to binder. There are protections against a user freeing a buffer
    while in use by the kernel, however there was a window where
    BC_FREE_BUFFER could be used to free a recently allocated buffer that
    was not completely initialized. This resulted in a use-after-free
    detected by KASAN with a malicious test program.

    This window is closed by setting the buffer's allow_user_free attribute
    to 0 when the buffer is allocated or when the user has previously freed
    it instead of waiting for the caller to set it. The problem was that
    when the struct buffer was recycled, allow_user_free was stale and set
    to 1 allowing a free to go through.

    UPSTREAM: binder: Add BINDER_GET_NODE_INFO_FOR_REF ioctl.

    This allows the context manager to retrieve information about nodes
    that it holds a reference to, such as the current number of
    references to those nodes.

    Such information can for example be used to determine whether the

    This information can then be passed on to the process holding the

    reduce resource usage.

    android: binder: fix the race mmap and alloc_new_buf_locked
