    ipv6: Remove all uses of LL_ALLOCATED_SPACE

    The macro LL_ALLOCATED_SPACE was ill-conceived. It applies the
    alignment to the sum of needed_headroom and needed_tailroom. As
    the amount that is then reserved for head room is needed_headroom
    with alignment, this means that the tail room left may be too small.

    This patch replaces all uses of LL_ALLOCATED_SPACE in net/ipv6
    with the macro LL_RESERVED_SPACE and direct reference to
    needed_tailroom.

    This also fixes the problem with needed_headroom changing between
    allocating the skb and reserving the head room.

    ipv6_sk_mc_lock rwlock becomes a spinlock.

    readers (inet6_mc_check()) now takes rcu_read_lock() instead of read
    lock. Writers dont need to disable BH anymore.

    struct ipv6_mc_socklist objects are reclaimed after one RCU grace
    period.

  • 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.

  • 75c78500d   bonding: remap muticast addresses without using dev_close() and dev_open() ... Browse Code »

    This patch fixes commit e36b9d16c6a6d0f59803b3ef04ff3c22c3844c10. The approach
    there is to call dev_close()/dev_open() whenever the device type is changed in
    order to remap the device IP multicast addresses to HW multicast addresses.
    This approach suffers from 2 drawbacks:

    *. It assumes tha the device is UP when calling dev_close(), or otherwise
    dev_close() has no affect. It is worth to mention that initscripts (Redhat)
    and sysconfig (Suse) doesn't act the same in this matter.
    *. dev_close() has other side affects, like deleting entries from the routing
    table, which might be unnecessary.

    The fix here is to directly remap the IP multicast addresses to HW multicast
    addresses for a bonding device that changes its type, and nothing else.

    OutMcastOctets:
    http://tools.ietf.org/html/rfc4293
    But it seems we don't track those in any way that easy to separate from other
    protocols. This patch adds those missing counters to the stats file. Tested
    successfully by me
