  • 2c38de4c1   netfilter: fix looped (broad|multi)cast's MAC handling ... Browse Code »

    By default, when broadcast or multicast packet are sent from a local
    application, they are sent to the interface then looped by the kernel
    to other local applications, going throught netfilter hooks in the
    process.

    These looped packet have their MAC header removed from the skb by the
    kernel looping code. This confuse various netfilter's netlink queue,
    netlink log and the legacy ip_queue, because they try to extract a
    hardware address from these packets, but extracts a part of the IP
    header instead.

    This patch prevent NFQUEUE, NFLOG and ip_QUEUE to include a MAC header
    if there is none in the packet.

    - must use hlist_add_head_rcu() instead of hlist_add_head()

    - must use hlist_del_rcu() instead of hlist_del()

  • 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.

  • a49c65037   netfilter: nfnetlink_log: fix silly refcount leak ... Browse Code »

    Quick fix for memory/module refcount leak.
    Reference count of listener instance never reaches 0.

    Start/stop of ulogd2 is enough to trigger this bug!

    Now, refcounting there looks very fishy in particular this code:

    if (!try_module_get(THIS_MODULE)) {
    ...

    and creation of listener instance with refcount 2,
    so it may very well be ripped and redone. :-)

  • ca735b3aa   netfilter: use a linked list of loggers ... Browse Code »

    This patch modifies nf_log to use a linked list of loggers for each
    protocol. This list of loggers is read and write protected with a
    mutex.

    This patch separates registration and binding. To be used as
    logging module, a module has to register calling nf_log_register()
    and to bind to a protocol it has to call nf_log_bind_pf().
    This patch also converts the logging modules to the new API. For nfnetlink_log,
    it simply switchs call to register functions to call to bind function and
    adds a call to nf_log_register() during init. For other modules, it just
    remove a const flag from the logger structure and replace it with a
    __read_mostly.

    NFLOG timeout was computed in timer by doing:

    flushtimeout*HZ/100

    Default value of flushtimeout was HZ (for 1 second delay). This was
    wrong for non 100HZ computer. This patch modify the default delay by
    using 100 instead of HZ.

    In NFLOG the per-rule qthreshold should overrides per-instance only
    it is set. With current code, the per-rule qthreshold is 1 if not set
    and it overrides the per-instance qthreshold.

    This patch modifies the default xt_NFLOG threshold from 1 to
    0. Thus a value of 0 means there is no per-rule setting and the instance
    parameter has to apply.
