bridge: Extend br_fill_ifinfo to return MPR status

2020-07-02T21:19:15Z

This patch extends the function br_fill_ifinfo to return also the MRP status for each instance on a bridge. It also adds a new filter RTEXT_FILTER_MRP to return the MRP status only when this is set, not to interfer with the vlans. The MRP status is return only on the bridge interfaces.

rtnetlink: add keepalived rtm_protocol

2020-06-23T21:35:12Z

Keepalived can set global static ip routes or virtual ip routes dynamically following VRRP protocol states. Using a dedicated rtm_protocol will help keeping track of it. Changes in v2: - fix tab/space indenting Signed-off-by: Alexandre Cassen Signed-off-by: David S. Miller

net: sched: introduce terse dump flag

2020-05-15T17:23:11Z

Add new TCA_DUMP_FLAGS attribute and use it in cls API to request terse filter output from classifiers with TCA_DUMP_FLAGS_TERSE flag. This option is intended to be used to improve performance of TC filter dump when userland only needs to obtain stats and not the whole classifier/action data. Extend struct tcf_proto_ops with new terse_dump() callback that must be defined by supporting classifier implementations. Support of the options in specific classifiers and actions is implemented in following patches in the series. Signed-off-by: Vlad Buslov Reviewed-by: Jiri Pirko Signed-off-by: David S. Miller

net: bridge: vlan: add rtnetlink group and notify support

2020-01-15T12:48:18Z

Add a new rtnetlink group for bridge vlan notifications - RTNLGRP_BRVLAN and add support for sending vlan notifications (both single and ranges). No functional changes intended, the notification support will be used by later patches. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

net: bridge: vlan: add rtm definitions and dump support

2020-01-15T12:48:17Z

This patch adds vlan rtm definitions: - NEWVLAN: to be used for creating vlans, setting options and notifications - DELVLAN: to be used for deleting vlans - GETVLAN: used for dumping vlan information Dumping vlans which can span multiple messages is added now with basic information (vid and flags). We use nlmsg_parse() to validate the header length in order to be able to extend the message with filtering attributes later. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

ipv4: Add "offload" and "trap" indications to routes

2020-01-15T02:53:35Z

When performing L3 offload, routes and nexthops are usually programmed into two different tables in the underlying device. Therefore, the fact that a nexthop resides in hardware does not necessarily mean that all the associated routes also reside in hardware and vice-versa. While the kernel can signal to user space the presence of a nexthop in hardware (via 'RTNH_F_OFFLOAD'), it does not have a corresponding flag for routes. In addition, the fact that a route resides in hardware does not necessarily mean that the traffic is offloaded. For example, unreachable routes (i.e., 'RTN_UNREACHABLE') are programmed to trap packets to the CPU so that the kernel will be able to generate the appropriate ICMP error packet. This patch adds an "offload" and "trap" indications to IPv4 routes, so that users will have better visibility into the offload process. 'struct fib_alias' is extended with two new fields that indicate if the route resides in hardware or not and if it is offloading traffic from the kernel or trapping packets to it. Note that the new fields are added in the 6 bytes hole and therefore the struct still fits in a single cache line [1]. Capable drivers are expected to invoke fib_alias_hw_flags_set() with the route's key in order to set the flags. The indications are dumped to user space via a new flags (i.e., 'RTM_F_OFFLOAD' and 'RTM_F_TRAP') in the 'rtm_flags' field in the ancillary header. v2: * Make use of 'struct fib_rt_info' in fib_alias_hw_flags_set() [1] struct fib_alias { struct hlist_node fa_list; /* 0 16 */ struct fib_info * fa_info; /* 16 8 */ u8 fa_tos; /* 24 1 */ u8 fa_type; /* 25 1 */ u8 fa_state; /* 26 1 */ u8 fa_slen; /* 27 1 */ u32 tb_id; /* 28 4 */ s16 fa_default; /* 32 2 */ u8 offload:1; /* 34: 0 1 */ u8 trap:1; /* 34: 1 1 */ u8 unused:6; /* 34: 2 1 */ /* XXX 5 bytes hole, try to pack */ struct callback_head rcu __attribute__((__aligned__(8))); /* 40 16 */ /* size: 56, cachelines: 1, members: 12 */ /* sum members: 50, holes: 1, sum holes: 5 */ /* sum bitfield members: 8 bits (1 bytes) */ /* forced alignments: 1, forced holes: 1, sum forced holes: 5 */ /* last cacheline: 56 bytes */ } __attribute__((__aligned__(8))); Signed-off-by: Ido Schimmel Reviewed-by: David Ahern Reviewed-by: Jiri Pirko Signed-off-by: David S.

net: rtnetlink: add linkprop commands to add and delete alternative ifnames

net: nexthop uapi

2019-05-29T04:37:30Z

New UAPI for nexthops as standalone objects: - defines netlink ancillary header, struct nhmsg - RTM commands for nexthop objects, RTM_*NEXTHOP, - RTNLGRP for nexthop notifications, RTNLGRP_NEXTHOP, - Attributes for creating nexthops, NHA_* - Attribute for route specs to specify a nexthop by id, RTA_NH_ID. The nexthop attributes and semantics follow the route and RTA ones for device, gateway and lwt encap. Unique to nexthop objects are a blackhole and a group which contains references to other nexthop objects. With the exception of blackhole and group, nexthop objects MUST contain a device. Gateway and encap are optional. Nexthop groups can only reference other pre-existing nexthops by id. If the NHA_ID attribute is present that id is used for the nexthop. If not specified, one is auto assigned. Dump requests can include attributes: - NHA_GROUPS to return only nexthop groups, - NHA_MASTER to limit dumps to nexthops with devices enslaved to the given master (e.g., VRF) - NHA_OIF to limit dumps to nexthops using given device nlmsg_route_perms in selinux code is updated for the new RTM comands.

net: sched: introduce chain object to uapi

2018-07-24T03:44:12Z

Allow user to create, destroy, get and dump chain objects. Do that by extending rtnl commands by the chain-specific ones. User will now be able to explicitly create or destroy chains (so far this was done only automatically according the filter/act needs and refcounting). Also, the user will receive notification about any chain creation or destuction. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller
