      sched, cbq: remove OVL_STRATEGY/POLICE support
      
      iproute2 does not implement any options that result in the
      TCA_CBQ_OVL_STRATEGY/TCA_CBQ_POLICE attributes being set/used.
      
      This series removes these two attributes from cbq and makes kernel reject
       them via EOPNOTSUPP in case they are present.
      
      The two followup changes then remove several features from qdisc
      infrastructure that are then no longer used/needed.  These are:
       - The 'drop' method provided by most qdiscs
       - the 'reshape_fail' function used by some qdiscs
       - the __parent member in struct Qdisc
      
      I tested this with allmod and allyesconfig builds and also with
      a brief cbq script:
      
        tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 10Mbit avpkt 1000 cell 8
        tc class add dev eth0 parent 1:0 classid 1:1 est 1sec 8sec cbq bandwidth 10Mbit rate 5Mbit prio 1 allot 1514 maxburst 20 cell 8 avpkt 1000 bounded split 1:0 defmap 3f
        tc class add dev eth0 parent 1:0 classid 1:2 est 1sec 8sec cbq bandwidth 10Mbit rate 5Mbit prio 1 allot 1514 maxburst 20 cell 8 avpkt 1000 bounded split 1:0 defmap 3f
        tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip tos 0x10 0xff classid 1:1 police rate 2Mbit burst 10K reclassify
        tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip tos 0x0c 0xff classid 1:2
        tc filter add dev eth0 parent 1:0 protocol ip prio 2 u32 match ip tos 0x10 0xff classid 1:2
        tc filter add dev eth0 parent 1:0 protocol ip prio 3 u32 match ip tos 0x0 0x0 classid 1:2
      
      No changes since v1 except patch #5 to fix up struct Qdisc layout.

      sched: place state, next_sched and gso_skb in same cacheline again · c8945043
      Florian Westphal 提交于
      Earlier commits removed two members from struct Qdisc which places
      next_sched/gso_skb into a different cacheline than ->state.
      
      This restores the struct layout to what it was before the removal.
      Move the two members, then add an annotation so they all reside in the
      same cacheline.
      
      This adds a 16 byte hole after cpu_qstats.
      
      The hole could be closed but as it doesn't decrease total struct size just
      do it this way.

      cbq: remove TCA_CBQ_POLICE support · dd47c1fa
      Florian Westphal 提交于
      iproute2 doesn't implement any cbq option that results in this attribute
      being sent to kernel.
      
      To make use of it, user would have to
      
      - patch iproute2
      - add a class
      - attach a qdisc to the class (default pfifo doesn't work as
        q->handle is 0 and cbq_set_police() is a no-op in this case)
      - re-'add' the same class (tc class change ...) again
      - user must also specifiy a defmap (e.g. 'split 1:0 defmap 3f'), since
        this 'police' feature relies on its presence
      - the added qdisc must be one of bfifo, pfifo or netem
      
      If all of these conditions are met and _some_ leaf qdiscs, namely
      p/bfifo, netem, plug or tbf would drop a packet, kernel calls back into
      cbq, which will attempt to re-queue the skb into a different class
      as indicated by the parents' defmap entry for TC_PRIO_BESTEFFORT.
      
      [ i.e. we behave as if tc_classify returned TC_ACT_RECLASSIFY ].
      
      This feature, which isn't documented or implemented in iproute2,
      and isn't implemented consistently (most qdiscs like sfq, codel, etc
      drop right away instead of attempting this reclassification) is the
      sole reason for the reshape_fail and __parent member in Qdisc struct.
      
      So remove TCA_CBQ_POLICE support from the kernel, reject it via EOPNOTSUPP
      so userspace knows we don't support it, and then remove no-longer needed
      infrastructure in followup commit.

      cbq: remove TCA_CBQ_OVL_STRATEGY support · c3498d34
      Florian Westphal 提交于
      since initial revision of cbq in 2004 iproute 2 has never implemented
      support for TCA_CBQ_OVL_STRATEGY, which is what needs to be set to
      activate the class->drop() call (TC_CBQ_OVL_DROP strategy must be
      set by userspace value must be set by userspace).
      
      David Miller says:
         It seems really safe to kill this thing off, flag an error if someone
         tries to set the attribute, and therefore kill off all of the
         non-default cbq_ovl_*() functions.
      
      A followup commit can then remove all .drop qdisc methods since this
      removed the only caller.

      net: vrf: Improve use of FIB rules
      
      Currently, VRFs require 1 oif and 1 iif rule per address family per
      VRF. As the number of VRF devices increases it brings scalability
      issues with the increasing rule list. All of the VRF rules have the
      same format with the exception of the specific table id to direct the
      lookup. Since the table id is available from the oif or iif in the
      loopup, the VRF rules can be consolidated to a single rule that pulls
      the table from the VRF device.
      
      This solution still allows a user to insert their own rules for VRFs,
      including rules with additional attributes. Accordingly, it is backwards
      compatible with existing setups and allows other policy routing as
      desired.
      
      Hopefully v5 is the charm; my e-waste can is getting full.

      net: Add l3mdev rule · 96c63fa7
      David Ahern 提交于
      Currently, VRFs require 1 oif and 1 iif rule per address family per
      VRF. As the number of VRF devices increases it brings scalability
      issues with the increasing rule list. All of the VRF rules have the

      loopup, the VRF rules can be consolidated to a single rule that pulls
      the table from the VRF device.
      
      This patch introduces a new rule attribute l3mdev. The l3mdev rule
      means the table id used for the lookup is pulled from the L3 master
      device (e.g., VRF) rather than being statically defined. With the
      l3mdev rule all of the basic VRF FIB rules are reduced to 1 l3mdev
      rule per address family (IPv4 and IPv6).
      
      If an admin wishes to insert higher priority rules for specific VRFs
      those rules will co-exist with the l3mdev rule. This capability means
      current VRF scripts will co-exist with this new simpler implementation.
      
      Currently, the rules list for both ipv4 and ipv6 look like this:
          $ ip  ru ls
          1000:       from all oif vrf1 lookup 1001

          1000:       from all iif vrf2 lookup 1002
          1000:       from all oif vrf3 lookup 1003
          1000:       from all iif vrf3 lookup 1003

          1000:       from all oif vrf7 lookup 1007
          1000:       from all iif vrf7 lookup 1007

          32766:      from all lookup main
          32767:      from all lookup default
      
      With the l3mdev rule the list is just the following regardless of the
      number of VRFs:
          $ ip ru ls
          1000:       from all lookup [l3mdev table]
          32765:      from all lookup local
          32766:      from all lookup main
          32767:      from all lookup default

             prototype. Actual verbage may change)

      tipc: change node timer unit from jiffies to ms · 5ca509fc
      Jon Paul Maloy 提交于
      The node keepalive interval is recalculated at each timer expiration
      to catch any changes in the link tolerance, and stored in a field in
      struct tipc_node. We use jiffies as unit for the stored value.
      
      This is suboptimal, because it makes the calculation unnecessary
      complex, including two unit conversions. The conversions also lead to
      a rounding error that causes the link "abort limit" to be 3 in the
      normal case, instead of 4, as intended. This again leads to unnecessary
      link resets when the network is pushed close to its limit, e.g., in an
      environment with hundreds of nodes or namesapces.
      
      In this commit, we do instead let the keepalive value be calculated and
      stored in milliseconds, so that there is only one conversion and the
      rounding error is eliminated.
      
      We also remove a redundant "keepalive" field in struct tipc_link. This
      is remnant from the previous implementation.

      tipc: correct error in node fsm · c4282ca7
      Jon Paul Maloy 提交于
      commit 88e8ac70 ("tipc: reduce transmission rate of reset messages
      when link is down") revealed a flaw in the node FSM, as defined in
      the log of commit 66996b6c ("tipc: extend node FSM").
      
      We see the following scenario:
      1: Node B receives a RESET message from node A before its link endpoint
         is fully up, i.e., the node FSM is in state SELF_UP_PEER_COMING. This
         event will not change the node FSM state, but the (distinct) link FSM
         will move to state RESETTING.
      2: As an effect of the previous event, the local endpoint on B will
         declare node A lost, and post the event SELF_DOWN to the its node
         FSM. This moves the FSM state to SELF_DOWN_PEER_LEAVING, meaning
         that no messages will be accepted from A until it receives another
         RESET message that confirms that A's endpoint has been reset. This
         is  wasteful, since we know this as a fact already from the first
         received RESET, but worse is that the link instance's FSM has not
         wasted this information, but instead moved on to state ESTABLISHING,
         meaning that it repeatedly sends out ACTIVATE messages to the reset
         peer A.
      3: Node A will receive one of the ACTIVATE messages, move its link FSM
         to state ESTABLISHED, and start repeatedly sending out STATE messages
         to node B.
      4: Node B will consistently drop these messages, since it can only accept
         accept a RESET according to its node FSM.
      5: After four lost STATE messages node A will reset its link and start
         repeatedly sending out RESET messages to B.
      6: Because of the reduced send rate for RESET messages, it is very
         likely that A will receive an ACTIVATE (which is sent out at a much
         higher frequency) before it gets the chance to send a RESET, and A
         may hence quickly move back to state ESTABLISHED and continue sending
         out STATE messages, which will again be dropped by B.
      7: GOTO 5.
      8: After having repeated the cycle 5-7 a number of times, node A will
         by chance get in between with sending a RESET, and the situation is
         resolved.
      
      Unfortunately, we have seen that it may take a substantial amount of
      time before this vicious loop is broken, sometimes in the order of
      minutes.
      
      We correct this by making a small correction to the node FSM: When a
      node in state SELF_UP_PEER_COMING receives a SELF_DOWN event, it now
      moves directly back to state SELF_DOWN_PEER_DOWN, instead of as now
      SELF_DOWN_PEER_LEAVING. This is logically consistent, since we don't
      need to wait for RESET confirmation from of an endpoint that we alread
      know has been reset. It also means that node B in the scenario above
      will not be dropping incoming STATE messages, and the link can come up
      immediately.
      
      Finally, a symmetry comparison reveals that the  FSM has a similar
      error when receiving the event PEER_DOWN in state PEER_UP_SELF_COMING.
      Instead of moving to PERR_DOWN_SELF_LEAVING, it should move directly
      to SELF_DOWN_PEER_DOWN. Although we have never seen any negative effect
      of this logical error, we choose fix this one, too.
      
      The node FSM looks as follows after those changes:

      ====================
      net: dsa: misc improvements
      
      This patch series builds on top of Andrew's "New DSA bind, switches as devices"
      patch set and does the following:
      
      - add a few helper functions/goodies for net/dsa/dsa2.c to be as close as possible
        from net/dsa/dsa.c in terms of what drivers can expect, in particular the slave
        MDIO bus and the enabled_port_mask and phy_mii_mask
      
      - fix the CPU port ethtools ops to work in a multiple tree setup since we can
        no longer assume a single tree is supported
      
      - make the bcm_sf2 driver register its own MDIO bus, yet assign it to
        ds->slave_mii_bus for everything to work in net/dsa/slave.c wrt. PHY probing,
        this is a tad cleaner than what we have now
      
      Changes in v2:
      
      Most of the previous patches have been dropped to just keep the relevant ones
      now.
      
      Changes in v3:
      - split the addition of the slave MII bus as a separate patch
      - properly unwind all operations at the right place and right time (ethtool ops,
        slave MDIO bus
      - fixed a few typos here and there
      
      Changes in v4:
      - removed superfluous dst agrument to dsa_cpu_port_ethtool_{setup,restore}

      net: dsa: bcm_sf2: Register our slave MDIO bus · 461cd1b0
      Florian Fainelli 提交于
      Register a slave MDIO bus which allows us to divert problematic
      read/writes towards conflicting pseudo-PHY address (30). Do no longer
      rely on DSA's slave_mii_bus, but instead provide our own implementation
      which offers more flexibility as to what to do, and when to register it.
      
      We need to register it by the time we are able to get access to our
      memory mapped registers, which is not until drv->setup() time. In order
      to avoid forward declarations, we need to re-order the function bodies a
      bit.

      net: dsa: Initialize CPU port ethtool ops per tree · 0c73c523
      Florian Fainelli 提交于
      Now that we can properly support multiple distinct trees in the system,
      using a global variable: dsa_cpu_port_ethtool_ops is getting clobbered
      as soon as the second switch tree gets probed, and we don't want that.
      
      We need to move this to be dynamically allocated, and since we can't
      really be comparing addresses anymore to determine first time
      initialization versus any other times, just move this to dsa.c and
      dsa2.c where the remainder of the dst/ds initialization happens.
      
      The operations teardown restores the master netdev's ethtool_ops to its
      original ethtool_ops pointer (typically within the Ethernet driver)

      net: dsa: Add initialization helper for CPU port ethtool_ops · af42192c
      Florian Fainelli 提交于
      Add a helper function: dsa_cpu_port_ethtool_init() which initializes a
      custom ethtool_ops structure with custom DSA ethtool operations for CPU
      ports. This is a preliminary change to move the initialization outside
      of net/dsa/slave.c.

      Some drivers rely on these two bitmasks to contain the correct values
      for them to successfully probe and initialize at drv->setup() time,
      calculate correct values to put in both masks as early as possible in
      dsa_get_ports_dn().
