  • 38f49e880   via-rhine: hardware VLAN support ... Browse Code »

    This patch adds VLAN hardware support for Rhine chips.

    The driver uses up to 3 additional bytes of buffer space when extracting
    802.1Q headers; PKT_BUF_SZ should still be sufficient.

    The initial code was provided by David Lv. I reworked it to use standard
    kernel facilities. Coding style clean up mostly follows via-velocity.

    Adapted to new interface for VLAN acceleration (per request of Jesse Gross).

  • 1ae5dc342   net: trans_start cleanups ... Browse Code »

    Now that core network takes care of trans_start updates, dont do it
    in drivers themselves, if possible. Drivers can avoid one cache miss
    (on dev->trans_start) in their start_xmit() handler.

    Exceptions are NETIF_F_LLTX drivers

    Converts the list and the core manipulating with it to be the same as uc_list.

    +uses two functions for adding/removing mc address (normal and "global"
    variant) instead of a function parameter.
    +removes dev_mcast.c completely.
    +exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
    manipulation with lists on a sandbox (used in bonding and 80211 drivers)

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • c0d7a0212   net/via-rhine: Fix scheduling while atomic bugs ... Browse Code »

    There are BUGs "scheduling while atomic" triggered by the timer
    rhine_tx_timeout(). They are caused by calling napi_disable() (with
    msleep()). This patch fixes it by moving most of the timer content to
    the workqueue function (similarly to other drivers, like tg3), with
    spin_lock() changed to BH version.

    Additionally, there is spin_lock_irq() moved in rhine_close() to
    exclude napi_disable() etc., also tg3's way.

  • 22580f894   drivers/net: fixed drivers that support netpoll use ndo_start_xmit() ... Browse Code »

    The NETPOLL API requires that interrupts remain disabled in
    netpoll_send_skb(). The use of spin_lock_irq() and spin_unlock_irq()
    in the NETPOLL API callbacks causes the interrupts to get enabled and
    can lead to kernel instability.

    The solution is to use spin_lock_irqsave() and spin_unlock_restore()
    to prevent the irqs from getting enabled while in netpoll_send_skb().

    Call trace:
    netpoll_send_skb()
    {
    -> local_irq_save(flags)
    ---> dev->ndo_start_xmit(skb, dev)
    ---> spin_lock_irq()
    ---> spin_unlock_irq() *******here would enable the interrupt.
    ...
    -> local_irq_restore(flags)
    }

    Following the removal of the unused struct net_device * parameter from
    the NAPI functions named *netif_rx_* in commit 908a7a1, they are
    exactly equivalent to the corresponding *napi_* functions and are
    therefore redundant.

    When the napi api was changed to separate its 1:1 binding to the net_device
    struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
    vestigual net_device structure parameter. This patch cleans up that api by
    properly removing it..

  • b74ca3a89   netdevice: Kill netdev->priv ... Browse Code »

    This is the last shoot of this series.
    After I removing all directly reference of netdev->priv, I am killing
    "priv" of "struct net_device" and fixing relative comments/docs.

    Anyone will not be allowed to reference netdev->priv directly.
    If you want to reference the memory of private data, use netdev_priv()
    instead.
    If the private data is not allocted when alloc_netdev(), use
    netdev->ml_priv to point that memory after you creating that private
    data.

    This converts pretty much everything to print_mac. There were
    a few things that had conflicts which I have just dropped for
    now, no harm done.

    I've built an allyesconfig with this and looked at the files
    that weren't built very carefully, but it's a huge patch.
