  • 3ff50b799   [NET]: cleanup extra semicolons ... Browse Code »

    Spring cleaning time...

    There seems to be a lot of places in the network code that have
    extra bogus semicolons after conditionals. Most commonly is a
    bogus semicolon after: switch() { }

  • 65f27f384   WorkStruct: Pass the work_struct pointer instead of context data ... Browse Code »

    Pass the work_struct pointer to the work function rather than context data.
    The work function can use container_of() to work out the data.

    For the cases where the container of the work_struct may go away the moment the
    pending bit is cleared, it is made possible to defer the release of the
    structure by deferring the clearing of the pending bit.

    To make this work, an extra flag is introduced into the management side of the
    work_struct. This governs auto-release of the structure upon execution.

    Ordinarily, the work queue executor would release the work_struct for further
    scheduling or deallocation by clearing the pending bit prior to jumping to the
    work function. This means that, unless the driver makes some guarantee itself
    that the work_struct won't go away, the work function may not access anything
    else in the work_struct or its container lest they be deallocated.. This is a
    problem if the auxiliary data is taken away (as done by the last patch).

    However, if the pending bit is *not* cleared before jumping to the work
    function, then the work function *may* access the work_struct and its container
    with no problems. But then the work function must itself release the
    work_struct by calling work_release().

    In most cases, automatic release is fine, so this is the default. Special
    initiators exist for the non-auto-release case (ending in _NAR).

  • 52bad64d9   WorkStruct: Separate delayable and non-delayable events. ... Browse Code »

    Separate delayable work items from non-delayable work items be splitting them
    into a separate structure (delayed_work), which incorporates a work_struct and
    the timer_list removed from work_struct.

    The work_struct struct is huge, and this limits it's usefulness. On a 64-bit
    architecture it's nearly 100 bytes in size. This reduces that by half for the
    non-delayable type of event.

  • 8c1056839   [NET] linkwatch: Handle jiffies wrap-around ... Browse Code »

    The test used in the linkwatch does not handle wrap-arounds correctly.
    Since the intention of the code is to eliminate bursts of messages we
    can afford to delay things up to a second. Using that fact we can
    easily handle wrap-arounds by making sure that we don't delay things
    by more than one second.

    This is based on diagnosis and a patch by Stefan Rompf.

    This patch turns the RTNL from a semaphore to a new 2.6.16 mutex and

  • b00055aac   [NET] core: add RFC2863 operstate ... Browse Code »

    this patch adds a dormant flag to network devices, RFC2863 operstate derived
    from these flags and possibility for userspace interaction. It allows drivers
    to signal that a device is unusable for user traffic without disabling
    queueing (and therefore the possibility for protocol establishment traffic to
    flow) and a userspace supplicant (WPA, 802.1X) to mark a device unusable
    without changes to the driver.

    It is the result of our long discussion. However I must admit that it
    represents what Jamal and I agreed on with compromises towards Krzysztof, but
    Thomas and Krzysztof still disagree with some parts. Anyway I think it should
    be applied.

  • cacaddf57   [NET]: Disable queueing when carrier is lost. ... Browse Code »

    Some network drivers call netif_stop_queue() when detecting loss of
    carrier. This leads to packets being queued up at the qdisc level for
    an unbound period of time. In order to prevent this effect, the core
    networking stack will now cease to queue packets for any device, that
    is operationally down (i.e. the queue is flushed and disabled).

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
