  • 6c80563c2   net_sched: act: pick a different type for act_xt ... Browse Code »

    In tcf_register_action() we check either ->type or ->kind to see if
    there is an existing action registered, but ipt action registers two
    actions with same type but different kinds. They should have different
    types too.

  • 1a29321ed   net_sched: act: Dont increment refcnt on replace ... Browse Code »

    This is a bug fix. The existing code tries to kill many
    birds with one stone: Handling binding of actions to
    filters, new actions and replacing of action
    attributes. A simple test case to illustrate:

    XXXX
    moja@fe1:~$ sudo tc actions add action drop index 12
    moja@fe1:~$ actions get action gact index 12
    action order 1: gact action drop
    random type none pass val 0
    index 12 ref 1 bind 0
    moja@fe1:~$ sudo tc actions replace action ok index 12
    moja@fe1:~$ actions get action gact index 12
    action order 1: gact action drop
    random type none pass val 0
    index 12 ref 2 bind 0
    XXXX

    The above shows the refcounf being wrongly incremented on replace.
    There are more complex scenarios with binding of actions to filters
    that i am leaving out that didnt work as well...

    This patch fixes:
    1) pass mask rather than size to tcf_hashinfo_init()
    2) the cleanup should be in reversed order in mirred_cleanup_module()

  • c1b52739e   pkt_sched: namespace aware act_mirred ... Browse Code »

    Eric Dumazet pointed out that act_mirred needs to find the current net_ns,
    and struct net pointer is not provided in the call chain. His original
    patch made use of current->nsproxy->net_ns to find the network namespace,
    but this fails to work correctly for userspace code that makes use of
    netlink sockets in different network namespaces. Instead, pass the
    "struct net *" down along the call chain to where it is needed.

    This version removes the ifb changes as Eric has submitted that patch
    separately, but is otherwise identical to the previous version.

  • bfe0d0298   net_sched: factorize qdisc stats handling ... Browse Code »

    HTB takes into account skb is segmented in stats updates.
    Generalize this to all schedulers.

    They should use qdisc_bstats_update() helper instead of manipulating
    bstats.bytes and bstats.packets

    Add bstats_update() helper too for classes that use
    gnet_stats_basic_packed fields.

    Note : Right now, TCQ_F_CAN_BYPASS shortcurt can be taken only if no
    stab is setup on qdisc.

  • 6ff9c3644   net sched: printk message severity ... Browse Code »

    The previous patch encourage me to go look at all the messages in
    the network scheduler and fix them. Many messages were missing
    any severity level. Some serious ones that should never happen
    were turned into WARN(), and the random noise messages that were
    handled changed to pr_debug().

  • 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.
