  • 1d7138de8   igmp: RCU conversion of in_dev->mc_list ... Browse Code »

    in_dev->mc_list is protected by one rwlock (in_dev->mc_list_lock).

    This can easily be converted to a RCU protection.

    Writers hold RTNL, so mc_list_lock is removed, not replaced by a
    spinlock.

  • 82efee149   ipv4: introduce __ip_dev_find() ... Browse Code »

    ip_dev_find(net, addr) finds a device given an IPv4 source address and
    takes a reference on it.

    Introduce __ip_dev_find(), taking a third argument, to optionally take
    the device reference. Callers not asking the reference to be taken
    should be in an rcu_read_lock() protected section.

  • 65324144b   net: RFC3069, private VLAN proxy arp support ... Browse Code »
    44

    This is to be used together with switch technologies, like RFC3069,
    that where the individual ports are not allowed to communicate with
    each other, but they are allowed to talk to the upstream router. As
    described in RFC 3069, it is possible to allow these hosts to
    communicate through the upstream router by proxy_arp'ing.

    This patch basically allow proxy arp replies back to the same
    interface (from which the ARP request/solicitation was received).

    Tunable per device via proc "proxy_arp_pvlan":
    /proc/sys/net/ipv4/conf/*/proxy_arp_pvlan

    This switch technology is known by different vendor names:
    - In RFC 3069 it is called VLAN Aggregation.
    - Cisco and Allied Telesyn call it Private VLAN.
    - Hewlett-Packard call it Source-Port filtering or port-isolation.
    - Ericsson call it MAC-Forced Forwarding (RFC Draft).

  • 28f6aeea3   net: restore ip source validation ... Browse Code »

    when using policy routing and the skb mark:
    there are cases where a back path validation requires us
    to use a different routing table for src ip validation than
    the one used for mapping ingress dst ip.
    One such a case is transparent proxying where we pretend to be
    the destination system and therefore the local table
    is used for incoming packets but possibly a main table would
    be used on outbound.
    Make the default behavior to allow the above and if users
    need to turn on the symmetry via sysctl src_valid_mark

    ipv4: add sysctl to accept packets with local source addresses

    Change fib_validate_source() to accept packets with a local source address when
    the "accept_local" sysctl is set for the incoming inet device. Combined with the
    previous patches, this allows to communicate between multiple local interfaces
    over the wire.

  • 71e27da96   [IPV4]: Restore old behaviour of default config values ... Browse Code »

    Previously inet devices were only constructed when addresses are added
    (or rarely in ipmr). Therefore the default config values they get are
    the ones at the time of these operations.

    Now that we're creating inet devices earlier, this changes the
    behaviour of default config values in an incompatible way (see bug
    #8519).

    This patch creates a compromise by setting the default values at the
    same point as before but only for those that have not been explicitly
    set by the user since the inet device's creation.

  • 31be30854   [IPV4]: Add default config support after inetdev_init ... Browse Code »

    Previously once inetdev_init has been called on a device any changes
    made to ipv4_devconf_dflt would have no effect on that device's
    configuration.

    This creates a problem since we have moved the point where
    inetdev_init is called from when an address is added to where the
    device is registered.

    This patch is the first half of a set that tries to mimic the old
    behaviour while still calling inetdev_init.

    It propagates any changes to ipv4_devconf_dflt to those devices that
    have not had the corresponding attribute set.

    The next patch will forcibly set all values at the point where
    inetdev_init was previously called.

  • e5ed63991   [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl ... Browse Code »

    The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
    introduces __in_dev_get_rcu() to cover the second case.

    1) RCU with refcnt should use in_dev_get().
    2) RCU without refcnt should use __in_dev_get_rcu().
    3) All others must hold RTNL and use __in_dev_get_rtnl().

    There is one exception in net/ipv4/route.c which is in fact a pre-existing
    race condition. I've marked it as such so that we remember to fix it.

    This patch is based on suggestions and prior work by Suzanne Wood and
    Paul McKenney.

    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!
