  • eb9399220   module_param: make bool parameters really bool (net & drivers/net) ... Browse Code »

    module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
    trick.

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

    (Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false).

  • ea1107338   net: Remove casts of void * ... Browse Code »

    Unnecessary casts of void * clutter the code.

    These are the remainder casts after several specific
    patches to remove netdev_priv and dev_priv.

    Done via coccinelle script:

    $ cat cast_void_pointer.cocci
    @@
    type T;
    T *pt;
    void *pv;
    @@

    - pt = (T *)pv;
    + pt = pv;

    This is an off by one. We would go past the end when we NUL terminate
    the "value" string at end of the function. The "value" buffer is
    allocated in irlan_client_parse_response() or
    irlan_provider_parse_command().

  • 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.

  • 524ad0a79   netdevice: safe convert to netdev_priv() #part-4 ... Browse Code »

    We have some reasons to kill netdev->priv:
    1. netdev->priv is equal to netdev_priv().
    2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
    netdev_priv() is more flexible than netdev->priv.
    But we cann't kill netdev->priv, because so many drivers reference to it
    directly.

    This patch is a safe convert for netdev->priv to netdev_priv(netdev).
    Since all of the netdev->priv is only for read.
    But it is too big to be sent in one mail.
    I split it to 4 parts and make every part smaller than 100,000 bytes,
    which is max size allowed by vger.

  • e174961ca   net: convert print_mac to %pM ... Browse Code »

    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.

    Even kernel 2.2.26 (sic) already contains the
    #undef CONFIG_IRLAN_SEND_GRATUITOUS_ARP
    with the comment "but for some reason the machine crashes if you use DHCP".

    Either someone finally looks into this or it's simply time to remove
    this dead code.

    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  • da7071d7e   [PATCH] mark struct file_operations const 8 ... Browse Code »

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

    dev_alloc_skb() on the TX path, and this patch fixes that.
