linux-toradex.git/net/bridge/br_sysfs_br.c, branch v4.8-rc1 Linux kernel for Apalis and Colibri modules net: bridge: add support for IGMP/MLD stats and export them via netlink 2016-06-30T10:18:24+00:00 Nikolay Aleksandrov nikolay@cumulusnetworks.com 2016-06-28T14:57:06+00:00 1080ab95e3c7bdd77870e209aff83c763fdcf439 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.

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).

bridge: a netlink notification should be sent when those attributes are changed by br_sysfs_br 2016-04-14T02:42:33+00:00 Xin Long lucien.xin@gmail.com 2016-04-08T16:03:31+00:00 047831a9b9c3e34410025df84f629c005f437e42 Now when we change the attributes of bridge or br_port by netlink, a relevant netlink notification will be sent, but if we change them by ioctl or sysfs, no notification will be sent. We should ensure that whenever those attributes change internally or from sysfs/ioctl, that a netlink notification is sent out to listeners. Also, NetworkManager will use this in the future to listen for out-of-band bridge master attribute updates and incorporate them into the runtime configuration. This patch is used for br_sysfs_br. and we also need to remove some rtnl_trylock in old functions so that we can call it in a common one. For group_addr_store, we cannot make it use store_bridge_parm, because it's not a string-to-long convert, we will add notification on it individually.
