2017-08-07net: switchdev: Remove bridge bypass support from switchdevArkadi Sharshevsky1-435/+0
Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded through the bridge code, making the switchdev's SELF bridge bypass implementation to be redundant. This implies several changes: - No need for dump infra in switchdev, DSA's special case is handled privately. - Remove obj_dump from switchdev_ops. - FDBs are removed from obj_add/del routines, due to the fact that they are offloaded through the bridge notification chain. - The switchdev_port_bridge_xx() and switchdev_port_fdb_xx() functions can be removed.

Add support for learning FDB through notification. The driver defers the hardware update via ordered work queue. In case of a successful FDB add a notification is sent back to bridge. In case of hw FDB del failure the static FDB will be deleted from the bridge, thus, the interface is moved to down state in order to indicate inconsistent situation.

2017-08-07xfrm: check that cached bundle is still validFlorian Westphal1-1/+2
Quoting Ilan Tayari: 1. Set up a host-to-host IPSec tunnel (or transport, doesn't matter) 2. Ping over IPSec, or do something to populate the pcpu cache 3. Join a MC group, then leave MC group 4. Try to ping again using same CPU as before -> traffic doesn't egress the machine at all Ilan debugged the problem down to the fact that one of the path dsts devices point to lo due to earlier dst_dev_put(). In this case, dst is marked as DEAD and we cannot reuse the bundle. The cache only asserted that the requested policy and that of the cached bundle match, but its not enough - also verify the path is still valid.

The DA of the packet is updated to the next segment and forwarded accordingly. - SEG6_LOCAL_ACTION_END_X: same as above, except that the packet is forwarded to the specified IPv6 next-hop. - SEG6_LOCAL_ACTION_END_DX6: decapsulate the packet and forward to inner IPv6 packet to the specified IPv6 next-hop. - SEG6_LOCAL_ACTION_END_B6: insert the specified SRH directly after the IPv6 header of the packet. - SEG6_LOCAL_ACTION_END_B6_ENCAP: encapsulate the packet within an outer IPv6 header, containing the specified SRH.

2017-08-07ipv6: sr: define core operations for seg6local lightweight tunnelDavid Lebrun5-2/+330
This patch implements a new type of lightweight tunnel named seg6local. A seg6local lwt is defined by a type of action and a set of parameters. The action represents the operation to perform on the packets matching the lwt's route, and is not necessarily an encapsulation. The set of parameters are arguments for the processing function. Each action is defined in a struct seg6_action_desc within seg6_action_table[]. This structure contains the action, mandatory attributes, the processing function, and a static headroom size required by the action. The mandatory attributes are encoded as a bitmask field. The static headroom is set to a non-zero value when the processing function always add a constant number of bytes to the skb (e.g. the header size for encapsulations). To facilitate rtnetlink-related operations such as parsing, fill_encap, and cmp_encap, each type of action parameter is associated to three function pointers, in seg6_action_params[]. All actions defined in seg6_local.h are detailed in [1].
