  • a883bf564   pkt_sched: act_police: Fix a rate estimator test. ... Browse Code »

    A commit c1b56878fb68e9c14070939ea4537ad4db79ffae "tc: policing requires
    a rate estimator" introduced a test which invalidates previously working
    configs, based on examples from iproute2: doc/actions/actions-general.
    This is too rigorous: a rate estimator is needed only when police's
    "avrate" option is used.

  • 244e6c2d0   pkt_sched: gen_estimator: Optimize gen_estimator_active() ... Browse Code »

    Since all other gen_estimator functions use bstats and rate_est params
    together, and searching for them is optimized now, let's use this also
    in gen_estimator_active(). The return type of gen_estimator_active()
    is changed to bool, and gen_find_node() parameters to const, btw.

    In tcf_act_police_locate() a check for ACT_P_CREATED is added before
    calling gen_estimator_active().

  • 547b792ca   net: convert BUG_TRAP to generic WARN_ON ... Browse Code »

    Removes legacy reinvent-the-wheel type thing. The generic
    machinery integrates much better to automated debugging aids
    such as kerneloops.org (and others), and is unambiguous due to
    better naming. Non-intuively BUG_TRAP() is actually equal to
    WARN_ON() rather than BUG_ON() though some might actually be
    promoted to BUG_ON() but I left that to future.

    I could make at least one BUILD_BUG_ON conversion.

    The NET_CLS_ACT option is now a full replacement for NET_CLS_POLICE,
    remove the old code. The config option will be kept around to select
    the equivalent NET_CLS_ACT options for a short time to allow easier
    upgrades.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

  • 1e9b3d533   [NET_SCHED]: policer: restore compatibility with old iproute binaries ... Browse Code »

    The tc actions increased the size of struct tc_police, which broke
    compatibility with old iproute binaries since both the act_police
    and the old NET_CLS_POLICE code check for an exact size match.

    Since the new members are not even used, the simple fix is to also
    accept the size of the old structure. Dumping is not affected since
    old userspace will receive a bigger structure, which is handled fine.

  • e9ce1cd3c   [PKT_SCHED]: Kill pkt_act.h inlining. ... Browse Code »

    This was simply making templates of functions and mostly causing a lot
    of code duplication in the classifier action modules.

    We solve this more cleanly by having a common "struct tcf_common" that
    hash worker functions contained once in act_api.c can work with.

    Callers work with real action objects that have the common struct
    plus their module specific struct members. You go from a common
    object to the higher level one using a "to_foo()" macro which makes
    use of container_of() to do the dirty work.

    This also kills off act_generic.h which was only used by act_simple.c
    and keeping it around was more work than the it's value.
