bridge: mrp: Extend bridge interface

2020-07-14T20:46:42Z

This patch adds a new flag(BR_MRP_LOST_IN_CONT) to the net bridge ports. This bit will be set when the port lost the continuity of MRP_InTest frames. Signed-off-by: Horatiu Vultur Acked-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

bridge: mrp: Extend bridge interface

2020-04-27T18:40:25Z

To integrate MRP into the bridge, first the bridge needs to be aware of ports that are part of an MRP ring and which rings are on the bridge. Therefore extend bridge interface with the following: - add new flag(BR_MPP_AWARE) to the net bridge ports, this bit will be set when the port is added to an MRP instance. In this way it knows if the frame was received on MRP ring port - add new flag(BR_MRP_LOST_CONT) to the net bridge ports, this bit will be set when the port lost the continuity of MRP Test frames. - add a list of MRP instances Reviewed-by: Nikolay Aleksandrov Signed-off-by: Horatiu Vultur Signed-off-by: David S.

bridge: broute: make broute a real ebtables table

2019-04-11T23:47:50Z

This makes broute a normal ebtables table, hooking at PREROUTING. The broute hook is removed. It uses skb->cb to signal to bridge rx handler that the skb should be routed instead of being bridged. This change is backwards compatible with ebtables as no userspace visible parts are changed. This means we can also remove the !ops test in ebt_register_table, it was only there for broute table sake. Signed-off-by: Florian Westphal Acked-by: David S.

bridge: Add br_fdb_clear_offload()

2018-12-07T20:59:08Z

When a driver unoffloads all FDB entries en bloc, it's inefficient to send the switchdev notification one by one. Add a helper that unsets the offload flag on FDB entries on a given bridge port and VLAN. Signed-off-by: Petr Machata Acked-by: Nikolay Aleksandrov Signed-off-by: Ido Schimmel Signed-off-by: David S.

bridge: Allow querying bridge port flags

2018-11-22T01:10:31Z

Allow querying bridge port flags so that drivers capable of performing VxLAN learning will update the bridge driver only if learning is enabled on its bridge port corresponding to the VxLAN device. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S. Miller

net: bridge: fix br_vlan_get_{pvid,info} return values

2018-07-07T11:04:35Z

These two functions return the regular -EINVAL failure in the normal code path, but return a nonstandard '-1' error otherwise, which gets interpreted as -EPERM. Let's change it to -EINVAL for the dummy functions as well.

net: bridge: add support for port isolation

2018-05-25T18:37:20Z

This patch adds support for a new port flag - BR_ISOLATED. If it is set then isolated ports cannot communicate between each other, but they can still communicate with non-isolated ports. The same can be achieved via ACLs but they can't scale with large number of ports and also the complexity of the rules grows. This feature can be used to achieve isolated vlan functionality (similar to pvlan) as well, though currently it will be port-wide (for all vlans on the port). The new test in should_deliver uses data that is already cache hot and the new boolean is used to avoid an additional source port test in should_deliver.
