rtnetlink: Add rtnexthop offload flag to compare mask

2016-10-19T15:07:57Z

The offload flag is a status flag and should not be used by FIB semantics for comparison. Fixes: 37ed9493699c ("rtnetlink: add RTNH_F_EXTERNAL flag for fib offload") Signed-off-by: Jiri Pirko Reviewed-by: Andy Gospodarek Signed-off-by: David S. Miller

rtnetlink: add new RTM_GETSTATS message to dump link stats

2016-04-20T19:43:42Z

This patch adds a new RTM_GETSTATS message to query link stats via netlink from the kernel. RTM_NEWLINK also dumps stats today, but RTM_NEWLINK returns a lot more than just stats and is expensive in some cases when frequent polling for stats from userspace is a common operation. RTM_GETSTATS is an attempt to provide a light weight netlink message to explicity query only link stats from the kernel on an interface. The idea is to also keep it extensible so that new kinds of stats can be added to it in the future. This patch adds the following attribute for NETDEV stats: struct nla_policy ifla_stats_policy[IFLA_STATS_MAX + 1] = { [IFLA_STATS_LINK_64] = { .len = sizeof(struct rtnl_link_stats64) }, }; Like any other rtnetlink message, RTM_GETSTATS can be used to get stats of a single interface or all interfaces with NLM_F_DUMP. Future possible new types of stat attributes: link af stats: - IFLA_STATS_LINK_IPV6 (nested. for ipv6 stats) - IFLA_STATS_LINK_MPLS (nested. for mpls/mdev stats) extended stats: - IFLA_STATS_LINK_EXTENDED (nested. extended software netdev stats like bridge, vlan, vxlan etc) - IFLA_STATS_LINK_HW_EXTENDED (nested. extended hardware stats which are available via ethtool today) This patch also declares a filter mask for all stat attributes. User has to provide a mask of stats attributes to query. filter mask can be specified in the new hdr 'struct if_stats_msg' for stats messages. Other important field in the header is the ifindex. This api can also include attributes for global stats (eg tcp) in the future. When global stats are included in a stats msg, the ifindex in the header must be zero. A single stats message cannot contain both global and netdev specific stats. To easily distinguish them, netdev specific stat attributes name are prefixed with IFLA_STATS_LINK_ Without any attributes in the filter_mask, no stats will be returned. This patch has been tested with mofified iproute2 ifstat. Suggested-by: Jamal Hadi Salim Signed-off-by: Roopa Prabhu Signed-off-by: David S. Miller

ipv6: allow routes to be configured with expire values

rtnetlink: RTEXT_FILTER_SKIP_STATS support to avoid dumping inet/inet6 stats

2015-09-15T22:25:02Z

Many commonly used functions like getifaddrs() invoke RTM_GETLINK to dump the interface information, and do not need the the AF_INET6 statististics that are always returned by default from rtnl_fill_ifinfo(). Computing the statistics can be an expensive operation that impacts scaling, so it is desirable to avoid this if the information is not needed. This patch adds a the RTEXT_FILTER_SKIP_STATS extended info flag that can be passed with netlink_request() to avoid statistics computation for the ifinfo path.

net: Allow user to get table id from route lookup

2015-09-15T19:01:41Z

rt_fill_info which is called for 'route get' requests hardcodes the table id as RT_TABLE_MAIN which is not correct when multiple tables are used. Use the newly added table id in the rtable to send back the correct table similar to what is done for IPv6. To maintain current ABI a new request flag, RTM_F_LOOKUP_TABLE, is added to indicate the actual table is wanted versus the hardcoded response. Signed-off-by: David Ahern Signed-off-by: David S.

fib, fib6: reject invalid feature bits

2015-08-31T19:34:00Z

Feature bits that are invalid should not be accepted by the kernel, only the lower 4 bits may be configured, but not the remaining ones. Even from these 4, 2 of them are unused. Signed-off-by: Daniel Borkmann Signed-off-by: David S. Miller
