  • b8a51b38e   fou, fou6: ICMP error handlers for FoU and GUE ... Browse Code »

    As the destination port in FoU and GUE receiving sockets doesn't
    necessarily match the remote destination port, we can't associate errors
    to the encapsulating tunnels with a socket lookup -- we need to blindly
    try them instead. This means we don't even know if we are handling errors
    for FoU or GUE without digging into the packets.

    Hence, implement a single handler for both, one for IPv4 and one for IPv6,
    that will check whether the packet that generated the ICMP error used a
    direct IP encapsulation or if it had a GUE header, and send the error to
    the matching protocol handler, if any.

  • dddb64bcb   net: Add sysctl to toggle early demux for tcp and udp ... Browse Code »

    Certain system process significant unconnected UDP workload.
    It would be preferrable to disable UDP early demux for those systems
    and enable it for TCP only.

    By disabling UDP demux, we see these slight gains on an ARM64 system-
    782 -> 788Mbps unconnected single stream UDPv4
    633 -> 654Mbps unconnected UDPv4 different sources

    The performance impact can change based on CPU architecure and cache
    sizes. There will not much difference seen if entire UDP hash table
    is in cache.

    Both sysctls are enabled by default to preserve existing behavior.

    v1->v2: Change function pointer instead of adding conditional as
    suggested by Stephen.

    v2->v3: Read once in callers to avoid issues due to compiler
    optimizations. Also update commit message with the tests.

    v3->v4: Store and use read once result instead of querying pointer
    again incorrectly.

    v4->v5: Refactor to avoid errors due to compilation with IPV6={m,n}

    Don't pretend that inet_protos[] and inet6_protos[] are hashes, thay
    are just a straight arrays. Remove all unnecessary hash masking.

    Document MAX_INET_PROTOS.

    Use RAW_HTABLE_SIZE when appropriate.

  • 03d4f879b   [IPV4]: align inet_protos[] on SMP ... Browse Code »

    As IPPROTO_TCP is 6, it makes sense to make sure inet_protos[] array
    is properly cache line aligned to avoid false sharing on SMP.

    c0680540 b peer_total
    c0680544 b inet_peer_unused_head
    c0680560 B inet_protos

    On i386 this example, we can see that inet_protos[IPPROTO_TCP] shares
    a potentially hot (and modified) cache line.

  • 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).

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
