    Remove the control.sta pointer from ieee80211_tx_info to free up
    sufficient space in the TX skb control buffer for the upcoming
    Transmit Power Control (TPC).
    Instead, the pointer is now on the stack in a new control struct
    that is passed as a function parameter to the drivers' tx method.

  • 2c208890c   wireless: Remove casts to same type ... Browse Code »

    Adding casts of objects to the same type is unnecessary
    and confusing for a human reader.

    For example, this cast:

    int y;
    int *p = (int *)&y;

    I used the coccinelle script below to find and remove these
    unnecessary casts. I manually removed the conversions this
    script produces of casts with __force, __iomem and __user.

    was doing odd things with array pointers and not using
    is_zero_ether_addr.

  • 7bb456837   mac80211: make tx() operation return void ... Browse Code »

    The return value of the tx operation is commonly
    misused by drivers, leading to errors. All drivers
    will drop frames if they fail to TX the frame, and
    they must also properly manage the queues (if they
    didn't, mac80211 would already warn).

    Removing the ability for drivers to return a BUSY
    value also allows significant cleanups of the TX
    TX handling code in mac80211.

    Note that this also fixes a bug in ath9k_htc, the
    old "return -1" there was wrong.

  • 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.

  • 3ac64beec   mac80211: allow configure_filter callback to sleep ... Browse Code »

    Over time, a whole bunch of drivers have come up
    with their own scheme to delay the configure_filter
    operation to a workqueue. To be able to simplify
    things, allow configure_filter to sleep, and add
    a new prepare_multicast callback that drivers that
    need the multicast address list implement. This new
    callback must be atomic, but most drivers either
    don't care or just calculate a hash which can be
    done atomically and then uploaded to the hardware
    non-atomically.

    A cursory look suggests that at76c50x-usb, ar9170,
    mwl8k (which is actually very broken now), rt2x00,
    wl1251, wl1271 and zd1211 should make use of this
    new capability.

  • f1d58c252   mac80211: push rx status into skb->cb ... Browse Code »

    Within mac80211, we often need to copy the rx status into
    skb->cb. This is wasteful, as drivers could be building it
    in there to start with. This patch changes the API so that
    drivers are expected to pass the RX status in skb->cb, now
    accessible as IEEE80211_SKB_RXCB(skb). It also updates all
    drivers to pass the rx status in there, but only by making
    them memcpy() it into place before the call to the receive
    function (ieee80211_rx(_irqsafe)). Each driver can now be
    optimised on its own schedule.

  • 566bfe5a8   mac80211: use hardware flags for signal/noise units ... Browse Code »

    trying to clean up the signal/noise code. the previous code in mac80211 had
    confusing names for the related variables, did not have much definition of
    what units of signal and noise were provided and used implicit mechanisms from
    the wireless extensions.

    this patch introduces hardware capability flags to let the hardware specify
    clearly if it can provide signal and noise level values and which units it can
    provide. this also anticipates possible new units like RCPI in the future.

    for signal:

    IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
    IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point
    IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW

    for noise we currently only have dBm:

    IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW

    if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
    to provide the maximum value (max_signal) it reports in order for applications
    to make sense of the signal values.

    i tried my best to find out for each driver what it can provide and update it
    but i'm not sure (?) for some of them and used the more conservative guess in
    doubt. this can be fixed easily after this patch has been merged by changing
    the hardware flags of the driver.
