    Which points at an instance of map_single that needs updating.

  • RFC 2203 requires the server to drop the request if it believes the
    RPCSEC_GSS context is out of sequence. The problem is that we have no way
    on the client to know why the server dropped the request. In order to avoid
    spinning forever trying to resend the request, the safe approach is
    therefore to always invalidate the RPCSEC_GSS context on every major
    timeout.

  • There are different tables for MTS firmwares. This should be taken into
    account while selecting the proper firmware.

  • Frank Bennett reported that ivtv was causing skype to crash. With help
    from one of their developers he showed it was a kernel problem.
    VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names
    that are too long and does not truncate them so corrupts a few bytes of
    the app data area.

    Possibly the names also want trimming but for now this should fix the
    corruption case.

  • Apparently the kernel developers no longer consider it proper
    etiquette to use __FUNCTION__; everyone must instead use __func__
    (even though it breaks with older compilers). And worse still, actual
    effort is being expended to sweep this change throughout the kernel
    source tree. Don't these people have better things to do? So...
    Completely clean out all use of __FUNCTION__ from the pvrusb2 driver
    (it was just in the sysfs interface). I'm not going to use __func__
    either. So there.

  • The pvrusb2 driver was getting had by this scenario:

    1. Task A calls kthread_stop() for task B.
    2. Before exiting, then Task B calls kthread_stop() for task C.

    The problem is, kthread_stop() wants to allocate an internal resource
    to itself (i.e. acquire a lock), which won't be released until
    kthread_stop() returns. But kthread_stop() won't return until task B
    is dead. But task B won't die until it finishes its call to
    kthread_stop() for task C, and that will block waiting on the resource
    already allocated inside task A. Deadlock.

    With the pvrusb2 driver, task A is the caller to pvr_exit(), task B is
    the control thread run inside of pvrusb2-context.c, and task C is any
    worker thread run inside of pvrusb2-hdw.c.

    This problem got introduced by the previous threading setup change,
    which was itself an attempt to fix a module tear-down race (which it
    actually did fix). The lesson here is that a task being waited on as
    part of a kthread_stop() simply cannot be allow to also issue a
    kthread_stop() - or we make sure not to issue the enclosing
    kthread_stop() until we know that the inner kthread_stop() has
    completed first. The solution for the pvrusb2 driver is some hackish
    code which changes the main control thread tear down into a two step
    process. This then makes it possible to delay issuing the
    kthread_stop() on the control thread until after we know that
    everything has been torn down first. (And yes, we really need that
    kthread_stop() because it's the only way to safely guarantee that a
    module-referencing kernel thread has safely returned back out of the
    module before we finally remove the module.)

  • Earlier fix to handle DVB feed thread aborts was overly-aggressive.
    We can take better advantage of what kthread_stop() can do. This

  • If a disconnect happens before initialization is completed, the
    pvrusb2 driver can accidentally touch dangling pointers. The whole
    initialization function must be protected by the big_lock, and once
    inside that lock, the initialization function should abort if it is
    discovered that a disconnect has already taken place.

  • The pvrusb2 driver - for basically forever - was not enforcing a
    proper module tear-down. Kernel threads are used inside the driver
    and all must be gone before the module can be safely removed. This
    changeset reimplements a chunk of pvrusb2-context.c to enforce this
    correctly. Unfortunately this is not a simple fix. The new
    implementation also cuts back on kernel thread usage; instead of there
    being 1 control thread per instance now it's just 1 control thread
    shared by all instances. (By dropping to a single thread then the
    module exit function can block on its shutdown and the thread itself
    can monitor and cleanly shut down all of the other instances first.)

  • Implement timed measurement of encoder operation for the first time it
    is run. This allows the driver to note when the encoder has been run
    successfully for at least 1/4 second. On top of that implement
    various bits to ensure that the encoder has been run once before
    digital streaming for OnAir devices. This is done via several core
    state machine tweaks.

  • If the device fails to stream, the feed thread will block forever
    waiting for buffers. But while in this state it was not looking for
    an exit condition from the driver DVB interface. This caused the
    thread to jam. Implement a new stop flag (which will be set
    appropriately) to tell the thread to stop.
