2011-12-03net: Add Open vSwitch kernel components.Jesse Gross
Open vSwitch is a multilayer Ethernet switch targeted at virtualized environments. In addition to supporting a variety of features expected in a traditional hardware switch, it enables fine-grained programmatic extension and flow-based control of the network. This control is useful in a wide variety of applications but is particularly important in multi-server virtualization deployments, which are often characterized by highly dynamic endpoints and the need to maintain logical abstractions for multiple tenants. The Open vSwitch datapath provides an in-kernel fast path for packet forwarding. It is complemented by a userspace daemon, ovs-vswitchd, which is able to accept configuration from a variety of sources and translate it into packet processing rules. See http://openvswitch.org for more information and userspace utilities. Signed-off-by: Jesse Gross <jesse@nicira.com>

2011-11-13net: introduce ethernet teaming deviceJiri Pirko
This patch introduces new network device called team. It supposes to be very fast, simple, userspace-driven alternative to existing bonding driver. Userspace library called libteam with couple of demo apps is available here: https://github.com/jpirko/libteam Note it's still in its dipers atm. team<->libteam use generic netlink for communication. That and rtnl suppose to be the only way to configure team device, no sysfs etc. Python binding of libteam was recently introduced. Daemon providing arpmon/miimon active-backup functionality will be introduced shortly. All what's necessary is already implemented in kernel team driver. v7->v8: - check ndo_ndo_vlan_rx_[add/kill]_vid functions before calling them. - use dev_kfree_skb_any() instead of dev_kfree_skb() v6->v7: - transmit and receive functions are not checked in hot paths. That also resolves memory leak on transmit when no port is present v5->v6: - changed couple of _rcu calls to non _rcu ones in non-readers v4->v5: - team_change_mtu() uses team->lock while travesing though port list - mac address changes are moved completely to jurisdiction of userspace daemon. This way the daemon can do FOM1, FOM2 and possibly other weird things with mac addresses. Only round-robin mode sets up all ports to bond's address then enslaved. - Extended Kconfig text v3->v4: - remove redundant synchronize_rcu from __team_change_mode() - revert "set and clear of mode_ops happens per pointer, not per byte" - extend comment of function __team_change_mode() v2->v3: - team_change_mtu() uses rcu version of list traversal to unwind - set and clear of mode_ops happens per pointer, not per byte - port hashlist changed to be embedded into team structure - error branch in team_port_enter() does cleanup now - fixed rtln->rtnl v1->v2: - modes are made as modules. Makes team more modular and extendable. - several commenters' nitpicks found on v1 were fixed - several other bugs were fixed. - note I ignored Eric's comment about roundrobin port selector as Eric's way may be easily implemented as another mode (mode "random") in future.

2011-09-16ipv6: Send ICMPv6 RSes only when RAs are acceptedTore Anderson
This patch improves the logic determining when to send ICMPv6 Router Solicitations, so that they are 1) always sent when the kernel is accepting Router Advertisements, and 2) never sent when the kernel is not accepting RAs. In other words, the operational setting of the "accept_ra" sysctl is used. The change also makes the special "Hybrid Router" forwarding mode ("forwarding" sysctl set to 2) operate exactly the same as the standard Router mode (forwarding=1). The only difference between the two was that RSes was being sent in the Hybrid Router mode only. The sysctl documentation describing the special Hybrid Router mode has therefore been removed. Rationale for the change: Currently, the value of forwarding sysctl is the only thing determining whether or not to send RSes. If it has the value 0 or 2, they are sent, otherwise they are not. This leads to inconsistent behaviour in the following cases: * accept_ra=0, forwarding=0 * accept_ra=0, forwarding=2 * accept_ra=1, forwarding=2 * accept_ra=2, forwarding=1 In the first three cases, the kernel will send RSes, even though it will not accept any RAs received in reply. In the last case, it will not send any RSes, even though it will accept and process any RAs received. (Most routers will send unsolicited RAs periodically, so suppressing RSes in the last case will merely delay auto-configuration, not prevent it.) Also, it is my opinion that having the forwarding sysctl control RS sending behaviour (completely independent of whether RAs are being accepted or not) is simply not what most users would intuitively expect to be the case.
