net/core: Add VF link state control

2013-06-14T00:51:04+00:00

Add netlink directives and ndo entry to allow for controling VF link, which can be in one of three states: Auto - VF link state reflects the PF link state (default) Up - VF link state is up, traffic from VF to VF works even if the actual PF link is down Down - VF link state is down, no traffic from/to this VF, can be of use while configuring the VF Signed-off-by: Rony Efraim Signed-off-by: Or Gerlitz Signed-off-by: David S.

bridge: Add a flag to control unicast packet flood.

2013-06-11T09:04:32+00:00

Add a flag to control flood of unicast traffic. By default, flood is on and the bridge will flood unicast traffic if it doesn't know the destination. When the flag is turned off, unicast traffic without an FDB will not be forwarded to the specified port. Signed-off-by: Vlad Yasevich Reviewed-by: Michael S. Tsirkin Signed-off-by: David S. Miller

bridge: Add flag to control mac learning.

2013-06-11T09:04:32+00:00

Allow user to control whether mac learning is enabled on the port. By default, mac learning is enabled. Disabling mac learning will cause new dynamic FDB entries to not be created for a particular port. Signed-off-by: Vlad Yasevich Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

vxlan: allow choosing destination port per vxlan

2013-04-29T15:53:12+00:00

Allow configuring the default destination port on a per-device basis. Adds new netlink paramater IFLA_VXLAN_PORT to allow setting destination port when creating new vxlan. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

vxlan: source compatiablity with IFLA_VXLAN_GROUP (v2)

2013-04-29T15:53:12+00:00

Source compatiability for build iproute2 was broken by: commit c7995c43facc6e5dea4de63fa9d283a337aabeb1 Author: Atzm Watanabe vxlan: Allow setting destination to unicast address. Since this commit has not made it upstream (still net-next), and better to avoid gratitious changes to exported API's; go back to original definition, and add a comment.

net: vlan: add 802.1ad support

2013-04-19T18:46:06+00:00

Add support for 802.1ad VLAN devices. This mainly consists of checking for ETH_P_8021AD in addition to ETH_P_8021Q in a couple of places and check offloading capabilities based on the used protocol. Configuration is done using "ip link": # ip link add link eth0 eth0.1000 \ type vlan proto 802.1ad id 1000 # ip link add link eth0.1000 eth0.1000.1000 \ type vlan proto 802.1q id 1000 52:54:00:12:34:56 > 92:b1:54:28:e4:8c, ethertype 802.1Q (0x8100), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 20.1.0.2 > 20.1.0.1: ICMP echo request, id 3003, seq 8, length 64 92:b1:54:28:e4:8c > 52:54:00:12:34:56, ethertype 802.1Q-QinQ (0x88a8), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 47944, offset 0, flags [none], proto ICMP (1), length 84) 20.1.0.1 > 20.1.0.2: ICMP echo reply, id 3003, seq 8, length 64 Signed-off-by: Patrick McHardy Signed-off-by: David S.

vxlan: Allow setting destination to unicast address.

2013-04-16T20:43:35+00:00

This patch allows setting VXLAN destination to unicast address. It allows that VXLAN can be used as peer-to-peer tunnel without multicast. v4: generalize struct vxlan_dev, "gaddr" is replaced with vxlan_rdst. "GROUP" attribute is replaced with "REMOTE". they are based by David Stevens's comments. v3: move a new attribute REMOTE into the last of an enum list based by Stephen Hemminger's comments. v2: use a new attribute REMOTE instead of GROUP based by Cong Wang's comments.

net: ipv6: add tokenized interface identifier support

2013-04-08T20:55:28+00:00

This patch adds support for IPv6 tokenized IIDs, that allow for administrators to assign well-known host-part addresses to nodes whilst still obtaining global network prefix from Router Advertisements. It is currently in draft status. The primary target for such support is server platforms where addresses are usually manually configured, rather than using DHCPv6 or SLAAC. By using tokenised identifiers, hosts can still determine their network prefix by use of SLAAC, but more readily be automatically renumbered should their network prefix change. [...] The disadvantage with static addresses is that they are likely to require manual editing should the network prefix in use change. If instead there were a method to only manually configure the static identifier part of the IPv6 address, then the address could be automatically updated when a new prefix was introduced, as described in [RFC4192] for example. In such cases a DNS server might be configured with such a tokenised interface identifier of ::53, and SLAAC would use the token in constructing the interface address, using the advertised prefix. [...] http://tools.ietf.org/html/draft-chown-6man-tokenised-ipv6-identifiers-02 The implementation is partially based on top of Mark K. Thompson's proof of concept. However, it uses the Netlink interface for configuration resp. data retrival, so that it can be easily extended in future. Successfully tested by myself.
