2015-02-27tipc: rename media/msg related definitionsErik Hugne4-6/+6
The TIPC_MEDIA_ADDR_SIZE and TIPC_MEDIA_ADDR_OFFSET names are misleading, as they actually define the size and offset of the whole media info field and not the address part.

2015-02-27tipc: fix nullpointer bug when subscribing to eventsErik Hugne1-19/+4
If a subscription request is sent to a topology server connection, and any error occurs (malformed request, oom or limit reached) while processing this request, TIPC should terminate the subscriber connection. While doing so, it tries to access fields in an already freed (or never allocated) subscription element leading to a nullpointer exception. We fix this by removing the subscr_terminate function and terminate the connection immediately upon any subscription failure.

2015-02-27tipc: only create header copy for name distr messagesErik Hugne1-1/+1
The TIPC name distributor pushes topology updates to the cluster neighbors. Currently this is done in a unicast manner, and the skb holding the update is cloned for each cluster member. This is unnecessary, as we only modify the destnode field in the header so we change it to do pskb_copy instead.

2015-02-27fib_trie: Remove leaf_infoAlexander Duyck1-307/+156
At this point the leaf_info hash is redundant. By adding the suffix length to the fib_alias hash list we no longer have need of leaf_info as we can determine the prefix length from fa_slen. So we can compress things by dropping the leaf_info structure from fib_trie and instead directly connect the leaves to the fib_alias hash list.

Make use of an empty spot in the alias to store the suffix length so that we don't need to pull that information from the leaf_info structure. This patch also makes a slight change to the user statistics. Instead of incrementing semantic_match_miss once per leaf_info miss we now just increment it once per leaf if a match was not found.

2015-02-27fib_trie: Replace plen with slen in leaf_infoAlexander Duyck1-33/+30
This replaces the prefix length variable in the leaf_info structure with a suffix length value, or host identifier length in bits. By doing this it makes it easier to sort out since the tnodes and leaf are carrying this value as well since it is compatible with the ->pos field in tnodes. I also cleaned up one spot that had some list manipulation that could be simplified. I basically updated it so that we just use hlist_add_head_rcu instead of calling hlist_add_before_rcu on the first node in the list.

2015-02-27multicast: Extend ip address command to enable multicast group join/leave onMadhu Challa7-7/+98
Joining multicast group on ethernet level via "ip maddr" command would not work if we have an Ethernet switch that does igmp snooping since the switch would not replicate multicast packets on ports that did not have IGMP reports for the multicast addresses. Linux vxlan interfaces created via "ip link add vxlan" have the group option that enables then to do the required join. By extending ip address command with option "autojoin" we can get similar functionality for openvswitch vxlan interfaces as well as other tunneling mechanisms that need to receive multicast traffic. The kernel code is structured similar to how the vxlan driver does a group join / leave. example: ip address add 224.1.1.10/24 dev eth5 autojoin ip address del 224.1.1.10/24 dev eth5 Signed-off-by: Madhu Challa <challa@noironetworks.com> Signed-off-by: David S.

2015-02-26bridge: fix link notification skb size calculation to include vlan rangesRoopa Prabhu1-7/+85
my previous patch skipped vlan range optimizations during skb size calculations for simplicity. This incremental patch considers vlan ranges during skb size calculations. This leads to a bit of code duplication in the fill and size calculation functions. But, I could not find a prettier way to do this. will take any suggestions. Previously, I had reused the existing br_get_link_af_size size calculation function to calculate skb size for notifications. Reusing it this time around creates some change in behaviour issues for the usual .get_link_af_size callback. This patch adds a new br_get_link_af_size_filtered() function to base the size calculation on the incoming filter flag and include vlan ranges.

2015-02-26rocker: put port in FORWADING state after leaving bridgeScott Feldman1-9/+30
Cleanup the port forwarding state transitions for the cases when the port joins or leaves a bridge, or is brought admin UP or DOWN. When port is bridged, we can rely on bridge driver putting port in correct state using STP callback into port driver, regardless if bridge is enabled for STP or not. When port is not bridged, we can reuse some of the STP code to enabled or disable forwarding depending on UP or DOWN. Tested by trying all the transitions from bridge/not bridge, and UP/DOWN, and verifying port is in the correct forwarding state after each transition.

2015-02-25net: dsa: bcm_sf2: add HW bridging supportFlorian Fainelli3-1/+171
Implement the bridge join, leave and set_stp callbacks by making that we do the following: - when a port joins the bridge, all existing ports in the bridge get their VLAN control register updated with that joining port - the joining port is including all existing bridge ports in its own VLAN control register The leave operation is fairly similar, special care must be taken to make sure that port leaving the bridging is not removing itself from its own VLAN control register. Since the various BR_* states apply directly to our HW semantics, we just need to translate these constants into their corresponding HW settings, and voila! We make sure to trigger a fast-ageing process for ports that are joining/leaving the bridge and transition from incompatible states, this is equivalent to triggering an ARL flush for that port.

2015-02-25net: dsa: integrate with SWITCHDEV for HW bridgingFlorian Fainelli5-0/+171
In order to support bridging offloads in DSA switch drivers, select NET_SWITCHDEV to get access to the port_stp_update and parent_get_id NDOs that we are required to implement. To facilitate the integratation at the DSA driver level, we implement 3 types of operations: - port_join_bridge - port_leave_bridge - port_stp_update DSA will resolve which switch ports that are currently bridge port members as some Switch hardware/drivers need to know about that to limit the register programming to just the relevant registers (especially for slow MDIO buses). We also take care of setting the correct STP state when slave network devices are brought up/down while being bridge members. Finally, when a port is leaving the bridge, we make sure we set in BR_STATE_FORWARDING state, otherwise the bridge layer would leave it disabled as a result of having left the bridge.

2015-02-25net: dsa: Ensure that port array elements are initialized before being usedGuenter Roeck3-17/+13
A network device notifier can be called for one or more of the created slave devices before all slave devices have been registered. This can result in a mismatch between ds->phys_port_mask and the registered devices by the time the call is made, and it can result in a slave device being added to a bridge before its entry in ds->ports[] has been initialized. Rework the initialization code to initialize entries in ds->ports[] in dsa_slave_create. With this change, dsa_slave_create no longer needs to return slave_dev but can return an error code instead.

2015-02-24i40e: Add support for getlink, setlink ndo opsNeerav Parikh6-22/+196
Add support for bridge offload ndo_ops getlink and setlink to enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE. The support is only enabled in case of a PF VSI and not available for any other VSI type. By default the i40e driver inserts a bridge as part of the bring-up when a FDIR type VSI and/or a FCoE VSI is created. This bridge is created in VEB mode by default i.e. after creating the bridge using "Add VEB" AQ command the loopback for the PF's default VSI is enabled. The patch adds capability where all the VSIs created as downlink to the bridge inherits the loopback property and enables loopback only if the uplink bridge is operating in VEB mode. Hence, there is no need to explicitly enable loopback as part of allocating resources for SR-IOV VFs and call to do that has been removed. In case a user-request is made either via "bridge" utility or using the bridge netlink interface that requires to change the hardware bridge mode then that would require a PF reset and rebuild of the switch hierarchy.

2015-02-23pktgen: Correct documentation of module name and commandBen Hutchings1-2/+2
Drop the '.o' suffix so this text properly covers both the built-in and modular cases. 'insmod pktgen' obviously won't work; the command should be modprobe. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-02-23samples/pktgen: Trap SIGINTBen Hutchings8-0/+8
Otherwise ^C stops the script, not just pktgen. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-02-23samples/pktgen: Use bash as interpreterBen Hutchings8-8/+8
These scripts use the non-POSIX 'function' and 'local' keywords so they won't work with every /bin/sh. We could drop 'function' as it is a no-op, but 'local' makes for cleaner scripts. Require use of bash. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-02-23samples/pktgen: Correct comments about the thread configBen Hutchings8-8/+9
They all claimed to be two CPU examples using eth1, eth2 but that is only true in one case! Rob Jones pointed out spelling and grammar errors here, which I've also corrected.

2015-02-23samples/pktgen: Delete unused function pg()Ben Hutchings8-40/+0
This function is not used and wouldn't do anything useful as pktgen does not have an 'inject' command. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
