Tom Herbert says: ==================== strp: Generalize stream parser to work with other socket types Add a read_sock protocol operation function that allows something like tcp_read_sock to be called for other protocol types. Specific changes in this patch set: - Add read_sock function to proto_ops. This has the same signature as tcp_read_sock. sk_read_actor_t is also defined in net.h. - Set peek_len and read_sock proto_op functions for TCPv4 and TCPv6 stream ops. - Remove references to tcp in strparser. - Call peek_len and read_sock operations from strparser instead of calling TCP specific functions. ==================== Signed-off-by: -

kcm and strparser need to work with any type of stream socket not just TCP. Eliminate references to TCP and call generic proto_ops functions of read_sock and peek_len. Also in strp_init check if the socket support the proto_ops read_sock and peek_len. Signed-off-by:

Richard Alpe says: ==================== tipc: introduce UDP replicast This series introduces UDP replicast. A concept where we emulate multicast by sending multiple unicast messages to configured peers. This allows TIPC to be used in environments where IP multicast is disabled. There is a corresponding patch series for the tipc user space tool that allows a user to add remote addresses to the replicast list. ==================== Signed-off-by: -
Richard Alpe authored
When using replicast a UDP bearer can have an arbitrary amount of remote ip addresses associated with it. This means we cannot simply add all remote ip addresses to an existing bearer data message as it might fill the message, leaving us with a truncated message that we can't safely resume. To handle this we introduce the new netlink command TIPC_NL_UDP_GET_REMOTEIP. This command is intended to be called when the bearer data message has the TIPC_NLA_UDP_MULTI_REMOTEIP flag set, indicating there are more than one remote ip (replicast). Signed-off-by:

Add UDP bearer options to netlink bearer get message. This is used by the tipc user space tool to display UDP options. The UDP bearer information is passed using either a sockaddr_in or sockaddr_in6 structs. This means the user space receiver should intermediately store the retrieved data in a large enough struct (sockaddr_strage) before casting to the proper IP version type. Signed-off-by:

Automatically learn UDP remote IP addresses of communicating peers by looking at the source IP address of incoming TIPC link configuration messages (neighbor discovery). This makes configuration slightly easier and removes the problematic scenario where a node receives directly addressed neighbor discovery messages sent using replicast which the node cannot "reply" to using mutlicast, leaving the link FSM in a limbo state.

This patch introduces UDP replicast. A concept where we emulate multicast by sending multiple unicast messages to configured peers. The purpose of replicast is mainly to be able to use TIPC in cloud environments where IP multicast is disabled. Using replicas to unicast multicast messages is costly as we have to copy each skb and send the copies individually. Signed-off-by:

Florian Fainelli says: ==================== net: dsa: Make bcm_sf2 utilize b53_common This patch series makes the bcm_sf2 driver utilize a large number of the core functions offered by the b53_common driver since the SWITCH_CORE registers are mostly register compatible with the switches driven by b53_common. In order to accomplish that, we just override the dsa_driver_ops callbacks that we need to. There are still integration specific logic from the bcm_sf2 that we cannot absorb into b53_common because it is just not there, mostly in the area of link management and power management, but most of the features are within b53_common now: VLAN, FDB, bridge Along the process, we also improve support for the BCM58xx SoCs, since those also have the same version of the switching IP that 7445 has (for which bcm_sf2 was developed). Changes in v3: - rebase against 145dd5f9 ("net: flush the softnet backlog in process context") Changes in v2: - rebased against "net: dsa: rename switch operations structure" ==================== Signed-off-by:

Now that we are using b53_common for most VLAN, FDB and bridge operations, delete all the redundant code that we had in bcm_sf2.c to keep only the integration specific logic that we have to deal with: power management, link management and the external interfaces (RGMII, MDIO). Signed-off-by:

Florian Fainelli authored
The Broadcom Starfighter2 is almost entirely register compatible with B53, yet for historical reasons came up first in the tree and is now being updated to utilize b53_common.c to the fullest extent possible. A few things need to be adjusted to allow that: - the switch "core" registers currently operate on a 32-bit address, whereas b53 passes a page + reg pair to offset from, so we need to convert that, thankfully there is a generic formula to do that - the link managemenent is not self contained with the B53/CORE register set, but instead is in the SWITCH_REG block which is part of the integration glue logic, so we keep that entirely custom here because this really is part of the existing bcm_sf2 implementation - there are additional power management constraints on the port's memories that make us keep the port_enable/disable callbacks custom for now, also, we support tagging whereas b53_common does not support that yet All the VLAN and bridge code is entirely identical though so, avoid duplicating it. Other things will be migrated in the future like EEE and possibly Wake-on-LAN. Signed-off-by:

In order to migrate the bcm_sf2 driver over to the b53 driver for most VLAN/FDB/bridge operations, we need to add support for the "join all VLANs" register and behavior which allows us to make a given port join all VLANs and avoid setting specific VLAN entries when it is leaving the bridge.

Jiri Pirko says: ==================== mlxsw: Introduce support for offload forward mark Ido says: This patchset enables the forwarding of certain control packets by the device instead of relying on the CPU to do the forwarding. The first two patches simplify the current switchdev offload forward infrastructure and make it usable for stacked devices. This is done by moving the packet and port marking to the bridge driver instead of the switch driver. Patches 3-5 add the mlxsw specific bits to support the forward mark. ==================== Signed-off-by: -
Ido Schimmel authored
Instead of trapping certain packets to the CPU and then relying on it to flood them we can instead make the device mirror them. The following packet types are mirrored: * DHCP: Broadcast packets that should be flooded by the device, but also trapped in case CPU is running the DHCP server. * IGMP query: Multicast packets that need to be forwarded to other bridge ports, but also trapped so that receiving netdev will be marked as a router port by the bridge driver. * ARP request: Broadcast packets that should be forwarded to other bridge ports, but also trapped in case requested IP is of the local machine. * ARP response: Unicast packets that should be forwarded by the bridge but also trapped in case response is directed at us. Set the trap action of such packets to mirror and mark them using 'offload_fwd_mark' to prevent the bridge driver from forwarding them itself. Note that OSPF packets are also marked despite their action being trap. The reason for this is that the device traps such packets in the pipeline after they were already flooded. Signed-off-by:

switchdev_port_fwd_mark_set() is used to set the 'offload_fwd_mark' of port netdevs so that packets being flooded by the device won't be flooded twice. It works by assigning a unique identifier (the ifindex of the first bridge port) to bridge ports sharing the same parent ID. This prevents packets from being flooded twice by the same switch, but will flood packets through bridge ports belonging to a different switch. This method is problematic when stacked devices are taken into account, such as VLANs. In such cases, a physical port netdev can have upper devices being members in two different bridges, thus requiring two different 'offload_fwd_mark's to be configured on the port netdev, which is impossible. The main problem is that packet and netdev marking is performed at the physical netdev level, whereas flooding occurs between bridge ports, which are not necessarily port netdevs. Instead, packet and netdev marking should really be done in the bridge driver with the switch driver only telling it which packets it already forwarded. The bridge driver will mark such packets using the mark assigned to the ingress bridge port and will prevent the packet from being forwarded through any bridge port sharing the same mark (i.e. having the same parent ID). Remove the current switchdev 'offload_fwd_mark' implementation and instead implement the proposed method. In addition, make rocker - the sole user of the mark - use the proposed method.

Currently in process_backlog(), the process_queue dequeuing is performed with local IRQ disabled, to protect against flush_backlog(), which runs in hard IRQ context. This patch moves the flush operation to a work queue and runs the callback with bottom half disabled to protect the process_queue against dequeuing. Since process_queue is now always manipulated in bottom half context, the irq disable/enable pair around the dequeue operation are removed. To keep the flush time as low as possible, the flush works are scheduled on all online cpu simultaneously, using the high priority work-queue and statically allocated, per cpu, work structs. Overall this change increases the time required to destroy a device to improve slightly the packets reinjection performances. Acked-by:
