  • 0c4e85813   [NET]: Wrap netdevice hardware header creation. ... Browse Code »

    Add inline for common usage of hardware header creation, and
    fix bug in IPV6 mcast where the assumption about negative return is
    an errno. Negative return from hard_header means not enough space
    was available,(ie -N bytes).

  • 0cc217e16   [IPV4]: When possible test for IFF_LOOPBACK and not dev == loopback_dev ... Browse Code »

    Now that multiple loopback devices are becoming possible it makes
    the code a little cleaner and more maintainable to test if a deivice
    is th a loopback device by testing dev->flags & IFF_LOOPBACK instead
    of dev == loopback_dev.

  • de3cb747f   [NET]: Dynamically allocate the loopback device, part 1. ... Browse Code »

    This patch replaces all occurences to the static variable
    loopback_dev to a pointer loopback_dev. That provides the
    mindless, trivial, uninteressting change part for the dynamic
    allocation for the loopback.

  • 881d966b4   [NET]: Make the device list and device lookups per namespace. ... Browse Code »

    This patch makes most of the generic device layer network
    namespace safe. This patch makes dev_base_head a
    network namespace variable, and then it picks up
    a few associated variables. The functions:
    dev_getbyhwaddr
    dev_getfirsthwbytype
    dev_get_by_flags
    dev_get_by_name
    __dev_get_by_name
    dev_get_by_index
    __dev_get_by_index
    dev_ioctl
    dev_ethtool
    dev_load
    wireless_process_ioctl

    were modified to take a network namespace argument, and
    deal with it.

    vlan_ioctl_set and brioctl_set were modified so their
    hooks will receive a network namespace argument.

    So basically anthing in the core of the network stack that was
    affected to by the change of dev_base was modified to handle
    multiple network namespaces. The rest of the network stack was
    simply modified to explicitly use &init_net the initial network
    namespace. This can be fixed when those components of the network
    stack are modified to handle multiple network namespaces.

    For now the ifindex generator is left global.

    Fundametally ifindex numbers are per namespace, or else
    we will have corner case problems with migration when
    we get that far.

    At the same time there are assumptions in the network stack
    that the ifindex of a network device won't change. Making
    the ifindex number global seems a good compromise until
    the network stack can cope with ifindex changes when
    you change namespaces, and the like.

  • e730c1551   [NET]: Make packet reception network namespace safe ... Browse Code »

    This patch modifies every packet receive function
    registered with dev_add_pack() to drop packets if they
    are not from the initial network namespace.

    This should ensure that the various network stacks do
    not receive packets in a anything but the initial network
    namespace until the code has been converted and is ready
    for them.

  • 457c4cbc5   [NET]: Make /proc/net per network namespace ... Browse Code »

    This patch makes /proc/net per network namespace. It modifies the global
    variables proc_net and proc_net_stat to be per network namespace.
    The proc_net file helpers are modified to take a network namespace argument,
    and all of their callers are fixed to pass &init_net for that argument.
    This ensures that all of the /proc/net files are only visible and
    usable in the initial network namespace until the code behind them
    has been updated to be handle multiple network namespaces.

    Making /proc/net per namespace is necessary as at least some files
    in /proc/net depend upon the set of network devices which is per
    network namespace, and even more files in /proc/net have contents
    that are relevant to a single network namespace.

  • dcbdc93c6   [IPCONFIG]: ip_auto_config fix ... Browse Code »

    The following commandline:

    root=/dev/mtdblock6 rw rootfstype=jffs2 ip=192.168.1.10:::255.255.255.0:localhost.localdomain:eth1:off console=ttyS0,115200

    makes ip_auto_config fall back to DHCP and complain "IP-Config: Incomplete
    network configuration information." depending on if CONFIG_IP_PNP_DHCP is
    set or not.

    The only way I can make ip_auto_config accept my IP config is to add an
    entry for the server IP:

    ip=192.168.1.10:192.168.1.15::255.255.255.0:localhost.localdomain:eth1:off

    I think this is a bug since I am not using a NFS root FS.

    The following patch fixes the above problem.

    From: Andrew Morton

    Davem said (in February!):

    Well, first of all the change in question is not in 2.4.x either. I just
    checked the current 2.4.x GIT tree and the test is exactly:

    if (ic_myaddr == INADDR_NONE ||
    #ifdef CONFIG_ROOT_NFS
    (MAJOR(ROOT_DEV) == UNNAMED_MAJOR
    && root_server_addr == INADDR_NONE
    && ic_servaddr == INADDR_NONE) ||
    #endif
    ic_first_dev->next) {

    which matches 2.6.x

    I even checked 2.4.x when it was branched for 2.5.x and the test was the
    same at the point in time too.

    Looking at the proposed change a bit it appears that it is probably
    correct, as it's trying to check that ROOT_DEV is nfs root. But if it is
    correct then the UNNAMED_MAJOR comparison in the same code block should be
    removed as it becomes superfluous.

    I'm happy to apply this patch with that modification made.

  • 7562f876c   [NET]: Rework dev_base via list_head (v3) ... Browse Code »

    Cleanup of dev_base list use, with the aim to simplify making device
    list per-namespace. In almost every occasion, use of dev_base variable
    and dev->next pointer could be easily replaced by for_each_netdev
    loop. A few most complicated places were converted to using
    first_netdev()/next_netdev().

  • 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.

  • 96b644bde   [PATCH] namespaces: utsname: use init_utsname when appropriate ... Browse Code »

    In some places, particularly drivers and __init code, the init utsns is the
    appropriate one to use. This patch replaces those with a the init_utsname
    helper.

    Changes: Removed several uses of init_utsname(). Hope I picked all the
    right ones in net/ipv4/ipconfig.c. These are now changed to
    utsname() (the per-process namespace utsname) in the previous
    patch (2/7)

  • f2ccd8fa0   [NET]: Kill skb->real_dev ... Browse Code »

    Bonding just wants the device before the skb_bond()
    decapsulation occurs, so simply pass that original
    device into packet_type->func() as an argument.

    It remains to be seen whether we can use this same
    exact thing to get rid of skb->input_dev as well.

  • 7a1af5d7b   [IPV4]: ipconfig.c: fix dhcp timeout behaviour ... Browse Code »

    I think there is a small bug in ipconfig.c in case IPCONFIG_DHCP is set
    and dhcp is used.

    When a DHCPOFFER is received, ip address is kept until we get DHCPACK.
    If no ack is received, ic_dynamic() returns negatively, but leaves the
    offered ip address in ic_myaddr.

    This makes the main loop in ip_auto_config() break and uses the maybe
    incomplete configuration.

    Not sure if it's the best way to do, but the following trivial patch
    correct this.

    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!
