  • Many (but not all) drivers check to see whether there is a vlan
    group configured before using a tag stored in the skb. There's
    not much point in this check since it just throws away data that
    should only be present in the expected circumstances. However,
    it will soon be legal and expected to get a vlan tag when no
    vlan group is configured, so remove this check from all drivers
    to avoid dropping the tags.

  • fresh skbs have ip_summed set to CHECKSUM_NONE (0)

    We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers.

    Introduce skb_checksum_none_assert() helper so that we keep this
    assertion documented in driver sources.

    Change most occurrences of :

    skb->ip_summed = CHECKSUM_NONE;

    by :

    skb_checksum_none_assert(skb);

  • This patch removes from drivers/net/ all the unnecessary
    return; statements that precede the last closing brace of
    void functions.

    It does not remove the returns that are immediately
    preceded by a label as gcc doesn't like that.

    It also does not remove null void functions with return.

    Done via:
    $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
    xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

    with some cleanups by hand.

    Compile tested x86 allmodconfig only.

  • 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)

  • …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.

  • Logging messages sometimes had duplicated "ATL1E" output.

    For instance:
    ATL1E 0000:03:00.0: ATL1E: eth0 NIC Link is Up
    is now:
    ATL1E 0000:03:00.0: eth0: NIC Link is Up

    Add some consistency to logging messages
    Add some missing \n's to logging messages
    Miscellaneous typo spelling corrections

  • Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round)

    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

    exactly equivalent to the corresponding *napi_* functions and are
    therefore redundant.
