  • f43798c27   tun: Allow GSO using virtio_net_hdr ... Browse Code »

    Add a IFF_VNET_HDR flag. This uses the same ABI as virtio_net
    (ie. prepending struct virtio_net_hdr to packets) to indicate GSO and
    checksum information.

  • 5228ddc98   tun: TUNSETFEATURES to set gso features. ... Browse Code »

    ethtool is useful for setting (some) device fields, but it's
    root-only. Finer feature control is available through a tun-specific
    ioctl.

    (Includes Mark McLoughlin 's fix to hold rtnl sem).

  • 07240fd09   tun: Interface to query tun/tap features. ... Browse Code »

    The problem with introducing checksum offload and gso to tun is they
    need to set dev->features to enable GSO and/or checksumming, which is
    supposed to be done before register_netdevice(), ie. as part of
    TUNSETIFF.

    Unfortunately, TUNSETIFF has always just ignored flags it doesn't
    understand, so there's no good way of detecting whether the kernel
    supports new IFF_ flags.

    This patch implements a TUNGETFEATURES ioctl which returns all the valid IFF
    flags. It could be extended later to include other features.

    Here's an example program which uses it:

    #include
    #include
    #include
    #include
    #include
    #include
    #include

    static struct {
    unsigned int flag;
    const char *name;
    } known_flags[] = {
    { IFF_TUN, "TUN" },
    { IFF_TAP, "TAP" },
    { IFF_NO_PI, "NO_PI" },
    { IFF_ONE_QUEUE, "ONE_QUEUE" },
    };

    int main()
    {
    unsigned int features, i;

    int netfd = open("/dev/net/tun", O_RDWR);
    if (netfd < 0)
    err(1, "Opening /dev/net/tun");

    if (ioctl(netfd, TUNGETFEATURES, &features) != 0) {
    printf("Kernel does not support TUNGETFEATURES, guessing\n");
    features = (IFF_TUN|IFF_TAP|IFF_NO_PI|IFF_ONE_QUEUE);
    }
    printf("Available features are: ");
    for (i = 0; i < sizeof(known_flags)/sizeof(known_flags[0]); i++) {
    if (features & known_flags[i].flag) {
    features &= ~known_flags[i].flag;
    printf("%s ", known_flags[i].name);
    }
    }
    if (features)
    printf("(UNKNOWN %#x)", features);
    printf("\n");
    return 0;
    }

  • 18ce3751c   Properly notify block layer of sync writes ... Browse Code »

    fsync_buffers_list() and sync_dirty_buffer() both issue async writes and
    then immediately wait on them. Conceptually, that makes them sync writes
    and we should treat them as such so that the IO schedulers can handle
    them appropriately.

    This patch fixes a write starvation issue that Lin Ming reported, where
    xx is stuck for more than 2 minutes because of a large number of
    synchronous IO in the system:

    INFO: task kjournald:20558 blocked for more than 120 seconds.
    "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this
    message.

    Lin Ming confirms that this patch fixes the issue. I've run tests with
    it for the past week and no ill effects have been observed, so I'm
    proposing it for inclusion into 2.6.26.
