    If riocm_get_channel() fails, then we should just return -EINVAL.
    Calling riocm_put_channel() will trigger a NULL dereference and
    generally we should call put() if the get() didn't succeed.

  • b92ae139c   rapidio/rio_cm: avoid GFP_KERNEL in atomic context ... Browse Code »

    As reported by Alexey Khoroshilov (https://lkml.org/lkml/2016/9/9/737):
    riocm_send_close() is called from rio_cm_shutdown() under
    spin_lock_bh(idr_lock), but riocm_send_close() uses a GFP_KERNEL
    allocation.

    Fix by taking riocm_send_close() outside of spinlock protected code.

  • 73984137d   rapidio: dereferencing an error pointer ... Browse Code »

    Original patch: https://lkml.org/lkml/2016/8/4/32

    If riocm_ch_alloc() fails then we end up dereferencing the error
    pointer.

    The problem is that we're not unwinding in the reverse order from how we
    allocate things so it gets confusing. I've changed this around so now
    "ch" is NULL when we are done with it after we call riocm_put_channel().
    That way we can check if it's NULL and avoid calling riocm_put_channel()
    on it twice.

    I renamed err_nodev to err_put_new_ch so that it better reflects what
    the goto does.

    Then because we had flipping things around, it means we don't neeed to
    initialize the pointers to NULL and we can remove an if statement and
    pull things in an indent level.

  • b6e8d4aa1   rapidio: add RapidIO channelized messaging driver ... Browse Code »

    Add channelized messaging driver to support native RapidIO messaging
    exchange between multiple senders/recipients on devices that use kernel
    RapidIO subsystem services.

    This device driver is the result of collaboration within the RapidIO.org
    Software Task Group (STG) between Texas Instruments, Prodrive
    Technologies, Nokia Networks, BAE and IDT. Additional input was
    received from other members of RapidIO.org.

    The objective was to create a character mode driver interface which
    exposes messaging capabilities of RapidIO endpoint devices (mports)
    directly to applications, in a manner that allows the numerous and
    varied RapidIO implementations to interoperate.

    This char mode device driver allows user-space applications to setup
    messaging communication channels using single shared RapidIO messaging
    mailbox.

    By default this driver uses RapidIO MBOX_1 (MBOX_0 is reserved for use by
    RIONET Ethernet emulation driver).
