  • 0b4d41471   [PATCH] sysctl: remove insert_at_head from register_sysctl ... Browse Code »

    The semantic effect of insert_at_head is that it would allow new registered
    sysctl entries to override existing sysctl entries of the same name. Which is
    pain for caching and the proc interface never implemented.

    I have done an audit and discovered that none of the current users of
    register_sysctl care as (excpet for directories) they do not register
    duplicate sysctl entries.

    So this patch simply removes the support for overriding existing entries in
    the sys_sysctl interface since no one uses it or cares and it makes future
    enhancments harder.

  • 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).

  • 9a32144e9   [PATCH] mark struct file_operations const 7 ... 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.

  • f5a6e01c0   [NET]: user of the jiffies rounding code: Networking ... Browse Code »

    This patch introduces users of the round_jiffies() function in the
    networking code.

    These timers all were of the "about once a second" or "about once
    every X seconds" variety and several showed up in the "what wakes the
    cpu up" profiles that the tickless patches provide. Some timers are
    highly dynamic based on network load; but even on low activity systems
    they still show up so the rounding is done only in cases of low
    activity, allowing higher frequency timers in the high activity case.

    The various hardware watchdogs are an obvious case; they run every 2
    seconds but aren't otherwise specific of exactly when they need to
    run.

  • 26932566a   [NETLINK]: Don't BUG on undersized allocations ... Browse Code »

    Currently netlink users BUG when the allocated skb for an event
    notification is undersized. While this is certainly a kernel bug,
    its not critical and crashing the kernel is too drastic, especially
    when considering that these errors have appeared multiple times in
    the past and it BUGs even if no listeners are present.

    This patch replaces BUG by WARN_ON and changes the notification
    functions to inform potential listeners of undersized allocations
    using a unique error code (EMSGSIZE).

  • e0e8f1c82   [IPSEC] flow: Fix potential memory leak ... Browse Code »

    When old flow cache entries that are not at the head of their chain
    trigger a transient security error they get unlinked along with all
    the entries preceding them in the chain. The preceding entries are
    not freed correctly.

    This patch fixes this by simply leaving the entry around. It's based
    on a suggestion by Venkat Yekkirala.

  • 47bbec028   [NETPOLL]: make arp replies through netpoll use mac address of sender ... Browse Code »

    Back in 2.4 arp requests that were recevied by netpoll were processed
    in netconsole_receive_skb, where they were responded to using the src
    mac of the request sender. In the 2.6 kernel arp_reply is responsible
    for this function, but instead of using the src mac address of the
    incomming request, the stored mac address that was registered for the
    netconsole application is used. While this is usually ok, it can lead
    to failures in netpoll in some situations (specifically situations
    where a network may have two gateways, as arp requests from one may be
    responded to using the mac address of the other). This patch reverts
    the behavior to what we had in 2.4, in which all arp requests are sent
    back using the src address of the request sender.

  • e16aa207c   [NET]: Memory barrier cleanups ... Browse Code »

    I believe all the below memory barriers only matter on SMP so
    therefore the smp_* variant of the barrier should be used.

    I'm wondering if the barrier in net/ipv4/inet_timewait_sock.c should be
    dropped entirely. schedule_work's implementation currently implies a
    memory barrier and I think sane semantics of schedule_work() should imply
    a memory barrier, as needed so the caller shouldn't have to worry.
    It's not quite obvious why the barrier in net/packet/af_packet.c is
    needed; maybe it should be implied through flush_dcache_page?
