rtnetlink: add restricted rtnl groups for ipv4 and ipv6 mroute

2017-06-21T15:22:52Z

Add RTNLGRP_{IPV4,IPV6}_MROUTE_R as two new restricted groups for the NETLINK_ROUTE family. Binding to these groups specifically requires CAP_NET_ADMIN to allow multicast of sensitive messages (e.g. mroute cache reports).

rtnetlink: add NEWCACHEREPORT message type

2017-06-21T15:22:52Z

New NEWCACHEREPORT message type to be used for cache reports sent via Netlink, effectively allowing splitting cache report reception from mroute programming. Suggested-by: Ryan Halbrook Signed-off-by: Julien Gomes Reviewed-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

net: ipv4: add new RTM_F_FIB_MATCH flag for use with RTM_GETROUTE

2017-05-26T18:12:50Z

This flag when specified will return matched fib result in response to a RTM_GETROUTE query. Signed-off-by: Roopa Prabhu Signed-off-by: David S. Miller

net: sched: introduce multichain support for filters

2017-05-17T19:22:13Z

Instead of having only one filter per block, introduce a list of chains for every block. Create chain 0 by default. UAPI is extended so the user can specify which chain he wants to change. If the new attribute is not specified, chain 0 is used. That allows to maintain backward compatibility. If chain does not exist and user wants to manipulate with it, new chain is created with specified index. Also, when last filter is removed from the chain, the chain is destroyed.

mpls: allow TTL propagation to IP packets to be configured

2017-03-13T22:29:22Z

Provide the ability to control on a per-route basis whether the TTL value from an MPLS packet is propagated to an IPv4/IPv6 packet when the last label is popped as per the theoretical model in RFC 3443 through a new route attribute, RTA_TTL_PROPAGATE which can be 0 to mean disable propagation and 1 to mean enable propagation. In order to provide the ability to change the behaviour for packets arriving with IPv4/IPv6 Explicit Null labels and to provide an easy way for a user to change the behaviour for all existing routes without having to reprogram them, a global knob is provided. This is done through the addition of a new per-namespace sysctl, "net.mpls.ip_ttl_propagate", which defaults to enabled. If the per-route attribute is set (either enabled or disabled) then it overrides the global configuration.

net: sched: make default fifo qdiscs appear in the dump

2017-03-13T05:53:02Z

The original reason [1] for having hidden qdiscs (potential scalability issues in qdisc_match_from_root() with single linked list in case of large amount of qdiscs) has been invalidated by 59cc1f61f0 ("net: sched: convert qdisc linked list to hashtable"). This allows us for bringing more clarity and determinism into the dump by making default pfifo qdiscs visible. We're not turning this on by default though, at it was deemed [2] too intrusive / unnecessary change of default behavior towards userspace. Instead, TCA_DUMP_INVISIBLE netlink attribute is introduced, which allows applications to request complete qdisc hierarchy dump, including the ones that have always been implicit/invisible. Singleton noop_qdisc stays invisible, as teaching the whole infrastructure about singletons would require quite some surgery with very little gain (seeing no qdisc or seeing noop qdisc in the dump is probably setting the same user expectation).

ipmr, ip6mr: add RTNH_F_UNRESOLVED flag to unresolved cache entries

2017-01-03T15:04:31Z

While working with ipmr, we noticed that it is impossible to determine if an entry is actually unresolved or its IIF interface has disappeared (e.g. virtual interface got deleted). These entries look almost identical to user-space when dumping or receiving notifications. So in order to recognize them add a new RTNH_F_UNRESOLVED flag which is set when sending an unresolved cache entry to user-space.

net: core: add UID to flows, rules, and routes

2016-11-04T18:45:23Z

- Define a new FIB rule attributes, FRA_UID_RANGE, to describe a range of UIDs. - Define a RTA_UID attribute for per-UID route lookups and dumps. - Support passing these attributes to and from userspace via rtnetlink. The value INVALID_UID indicates no UID was specified. - Add a UID field to the flow structures. Signed-off-by: Lorenzo Colitti Signed-off-by: David S. Miller
