* bridge: move to workqueue gcNikolay Aleksandrov2017-02-061-1/+1
| | | | | | | | | | | | | Move the fdb garbage collector to a workqueue which fires at least 10 milliseconds apart and cleans chain by chain allowing for other tasks to run in the meantime. When having thousands of fdbs the system is much more responsive. Most importantly remove the need to check if the matched entry has expired in __br_fdb_get that causes false-sharing and is completely unnecessary if we cleanup entries, at worst we'll get 10ms of traffic for that entry before it gets deleted.

* bridge: per vlan dst_metadata netlink supportRoopa Prabhu2017-02-031-45/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to attach per vlan tunnel info dst metadata. This enables bridge driver to map vlan to tunnel_info at ingress and egress. It uses the kernel dst_metadata infrastructure. The initial use case is vlan to vni bridging, but the api is generic to extend to any tunnel_info in the future: - Uapi to configure/unconfigure/dump per vlan tunnel data - netlink functions to configure vlan and tunnel_info mapping - Introduces bridge port flag BR_LWT_VLAN to enable attach/detach dst_metadata to bridged packets on ports. off by default. - changes to existing code is mainly refactor some existing vlan handling netlink code + hooks for new vlan tunnel code - I have kept the vlan tunnel code isolated in separate files. - most of the netlink vlan tunnel code is handling of vlan-tunid ranges (follows the vlan range handling code). To conserve space vlan-tunid by default are always dumped in ranges if applicable. Use case: example use for this is a vxlan bridging gateway or vtep which maps vlans to vn-segments (or vnis). iproute2 example (patched and pruned iproute2 output to just show relevant fdb entries): example shows same host mac learnt on two vni's and vlan 100 maps to vni 1000, vlan 101 maps to vni 1001 before (netdev per vni): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan1001 vlan 101 master bridge 00:02:00:00:00:03 dev vxlan1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan1000 vlan 100 master bridge 00:02:00:00:00:03 dev vxlan1000 dst 12.0.0.8 self after this patch with collect metdata in bridged mode (single netdev): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan0 vlan 101 master bridge 00:02:00:00:00:03 dev vxlan0 src_vni 1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan0 vlan 100 master bridge 00:02:00:00:00:03 dev vxlan0 src_vni 1000 dst 12.0.0.8 self CC: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David S.

* | bridge: multicast to unicastFelix Fietkau2017-01-241-0/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Implements an optional, per bridge port flag and feature to deliver multicast packets to any host on the according port via unicast individually. This is done by copying the packet per host and changing the multicast destination MAC to a unicast one accordingly. multicast-to-unicast works on top of the multicast snooping feature of the bridge. Which means unicast copies are only delivered to hosts which are interested in it and signalized this via IGMP/MLD reports previously. This feature is intended for interface types which have a more reliable and/or efficient way to deliver unicast packets than broadcast ones (e.g. wifi). However, it should only be enabled on interfaces where no IGMPv2/MLDv1 report suppression takes place. This feature is disabled by default. The initial patch and idea is from Felix Fietkau.

* net: bridge: consolidate bridge and port linkxstats callsNikolay Aleksandrov2016-08-181-75/+39
| | | | | | | | | | | | In the bridge driver we usually have the same function working for both port and bridge. In order to follow that logic and also avoid code duplication, consolidate the bridge_ and brport_ linkxstats calls into one since they share most of their code. As a side effect this allows us to dump the vlan stats also via the slave call which is in preparation for the upcoming per-port vlan stats and vlan flag dumping.

* net: bridge: add support for IGMP/MLD stats and export them via netlinkNikolay Aleksandrov2016-06-301-26/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds stats support for the currently used IGMP/MLD types by the bridge. The stats are per-port (plus one stat per-bridge) and per-direction (RX/TX). The stats are exported via netlink via the new linkxstats API (RTM_GETSTATS). In order to minimize the performance impact, a new option is used to enable/disable the stats - multicast_stats_enabled, similar to the recent vlan stats. Also in order to avoid multiple IGMP/MLD type lookups and checks, we make use of the current "igmp" member of the bridge private skb->cb region to record the type on Rx (both host-generated and external packets pass by multicast_rcv()). We can do that since the igmp member was used as a boolean and all the valid IGMP/MLD types are positive values. The normal bridge fast-path is not affected at all, the only affected paths are the flooding ones and since we make use of the IGMP/MLD type, we can quickly determine if the packet should be counted using cache-hot data (cb's igmp member). We add counters for: * IGMP Queries * IGMP Leaves * IGMP v1/v2/v3 reports * MLD Queries * MLD Leaves * MLD v1/v2 reports These are invaluable when monitoring or debugging complex multicast setups with bridges.

* net: rtnetlink: add support for the IFLA_STATS_LINK_XSTATS_SLAVE attributeNikolay Aleksandrov2016-06-301-3/+56
| | | | | | | | | | | | | | | This patch adds support for the IFLA_STATS_LINK_XSTATS_SLAVE attribute which allows to export per-slave statistics if the master device supports the linkxstats callback. The attribute is passed down to the linkxstats callback and it is up to the callback user to use it (an example has been added to the only current user - the bridge). This allows us to query only specific slaves of master devices like bridge ports and export only what we're interested in instead of having to dump all ports and searching only for a single one. This will be used to export per-port IGMP/MLD stats and also per-port vlan stats in the future, possibly other statistics as well.

* bridge: vlan: learn to countNikolay Aleksandrov2016-05-021-1/+12
| | | | | | | | | | | | | | | | Add support for per-VLAN Tx/Rx statistics. Every global vlan context gets allocated a per-cpu stats which is then set in each per-port vlan context for quick access. The br_allowed_ingress() common function is used to account for Rx packets and the br_handle_vlan() common function is used to account for Tx packets. Stats accounting is performed only if the bridge-wide vlan_stats_enabled option is set either via sysfs or netlink. A struct hole between vlan_enabled and vlan_proto is used for the new option so it is in the same cache line. Currently it is binary (on/off) but it is intentionally restricted to exactly 0 and 1 since other values will be used in the future for different purposes (e.g. per-port stats).

* netlink: Rightsize IFLA_AF_SPEC size calculationArad, Ronen2015-10-211-20/+1
| | | | | | | | | | | | | | | | | | | | | | | | if_nlmsg_size() overestimates the minimum allocation size of netlink dump request (when called from rtnl_calcit()) or the size of the message (when called from rtnl_getlink()). This is because ext_filter_mask is not supported by rtnl_link_get_af_size() and rtnl_link_get_size(). The over-estimation is significant when at least one netdev has many VLANs configured (8 bytes for each configured VLAN). This patch-set "rightsizes" the protocol specific attribute size calculation by propagating ext_filter_mask to rtnl_link_get_af_size() and adding this a argument to get_link_af_size op in rtnl_af_ops. Bridge module already used filtering aware sizing for notifications. br_get_link_af_size_filtered() is consistent with the modified get_link_af_size op so it replaces br_get_link_af_size() in br_af_ops. br_get_link_af_size() becomes unused and thus removed.
