      net: Remove usage of net_device last_rx member · 4a7c9726
      Tobias Klauser authored
      The network stack no longer uses the last_rx member of struct net_device
      since the bonding driver switched to use its own private last_rx in
      commit 9f242738 ("bonding: use last_arp_rx in slave_last_rx()").
      
      However, some drivers still (ab)use the field for their own purposes and
      some driver just update it without actually using it.
      
      Previously, there was an accompanying comment for the last_rx member
      added in commit 4dc89133 ("net: add a comment on netdev->last_rx")
      which asked drivers not to update is, unless really needed. However,
      this commend was removed in commit f8ff080d
      
       ("bonding: remove
      useless updating of slave->dev->last_rx"), so some drivers added later
      on still did update last_rx.
      
      Remove all usage of last_rx and switch three drivers (sky2, atp and
      smc91c92_cs) which actually read and write it to use their own private
      copy in netdev_priv.
      
      Compile-tested with allyesconfig and allmodconfig on x86 and arm.

      net: dsa: use cpu_switch instead of ds[0] · 9520ed8f
      Vivien Didelot authored
      
      
      Now that the DSA Ethernet switches are true Linux devices, the CPU
      switch is not necessarily the first one. If its address is higher than
      the second switch on the same MDIO bus, its index will be 1, not 0.
      
      Avoid any confusion by using dst->cpu_switch instead of dst->ds[0].

      Merge branch 'vhost_net-batching' · e3e37e70

      ====================
      vhost_net tx batching
      
      This series tries to implement tx batching support for vhost. This was
      done by using MSG_MORE as a hint for under layer socket. The backend
      (e.g tap) can then batch the packets temporarily in a list and
      submit it all once the number of bacthed exceeds a limitation.
      
      Tests shows obvious improvement on guest pktgen over over
      mlx4(noqueue) on host:
      
                                           Mpps  -+%
              rx-frames = 0                0.91  +0%
              rx-frames = 4                1.00  +9.8%
              rx-frames = 8                1.00  +9.8%
              rx-frames = 16               1.01  +10.9%
              rx-frames = 32               1.07  +17.5%
              rx-frames = 48               1.07  +17.5%
              rx-frames = 64               1.08  +18.6%
              rx-frames = 64 (no MSG_MORE) 0.91  +0%
      
      Changes from V4:
      - stick to NAPI_POLL_WEIGHT for rx-frames is user specify a value
        greater than it.
      Changes from V3:
      - use ethtool instead of module parameter to control the maximum
        number of batched packets
      - avoid overhead when MSG_MORE were not set and no packet queued
      Changes from V2:
      - remove uselss queue limitation check (and we don't drop any packet now)
      Changes from V1:
      - drop NAPI handler since we don't use NAPI now
      - fix the issues that may exceeds max pending of zerocopy
      - more improvement on available buffer detection
      - move the limitation of batched pacekts from vhost to tuntap

      tun: rx batching · 5503fcec
      Jason Wang authored
      
      
      We can only process 1 packet at one time during sendmsg(). This often
      lead bad cache utilization under heavy load. So this patch tries to do
      some batching during rx before submitting them to host network
      stack. This is done through accepting MSG_MORE as a hint from
      sendmsg() caller, if it was set, batch the packet temporarily in a
      linked list and submit them all once MSG_MORE were cleared.
      
      Tests were done by pktgen (burst=128) in guest over mlx4(noqueue) on host:
      
                                       Mpps  -+%
          rx-frames = 0                0.91  +0%
          rx-frames = 4                1.00  +9.8%
          rx-frames = 8                1.00  +9.8%
          rx-frames = 16               1.01  +10.9%
          rx-frames = 32               1.07  +17.5%
          rx-frames = 48               1.07  +17.5%
          rx-frames = 64               1.08  +18.6%
          rx-frames = 64 (no MSG_MORE) 0.91  +0%
      
      User were allowed to change per device batched packets through
      ethtool -C rx-frames. NAPI_POLL_WEIGHT were used as upper limitation
      to prevent bh from being disabled too long.

      vhost: better detection of available buffers · 275bf960
      Jason Wang authored
      
      
      This patch tries to do several tweaks on vhost_vq_avail_empty() for a
      better performance:
      
      - check cached avail index first which could avoid userspace memory access.
      - using unlikely() for the failure of userspace access
      - check vq->last_avail_idx instead of cached avail index as the last
        step.
      
      This patch is need for batching supports which needs to peek whether
      or not there's still available buffers in the ring.

      net:add one common config ARCH_WANT_RELAX_ORDER to support relax ordering · 1a8b6d76
      Mao Wenan authored
      
      
      Relax ordering(RO) is one feature of 82599 NIC, to enable this feature can
      enhance the performance for some cpu architecure, such as SPARC and so on.
      Currently it only supports one special cpu architecture(SPARC) in 82599
      driver to enable RO feature, this is not very common for other cpu architecture
      which really needs RO feature.
      This patch add one common config CONFIG_ARCH_WANT_RELAX_ORDER to set RO feature,
      and should define CONFIG_ARCH_WANT_RELAX_ORDER in sparc Kconfig firstly.

      be set, until the patch "sctp: add get and set sockopt for reconf_enable"
      is applied in the future. As we can not just enable it when sctp is not
      capable of processing reconf chunk yet.
      
      v1->v2:
        - put these into a smaller group.
        - rename some temporary variables in the codes.
        - rename the titles of the commits and improve some changelogs.
      v2->v3:
        - re-split the patchset and make sure it has no dead codes for review.
      v3->v4:
        - move sctp_make_reconf() into patch 1/6 to avoid kbuild warning.
        - drop unused struct sctp_strreset_req.

      sctp: add stream reconf timer · 7b9438de
      Xin Long authored
      
      
      This patch is to add a per transport timer based on sctp timer frame
      for stream reconf chunk retransmission. It would start after sending
      a reconf request chunk, and stop after receiving the response chunk.
      
      If the timer expires, besides retransmitting the reconf request chunk,
      it would also do the same thing with data RTO timer. like to increase
      the appropriate error counts, and perform threshold management, possibly
      destroying the asoc if sctp retransmission thresholds are exceeded, just
      as section 5.1.1 describes.
      
      This patch is also to add asoc strreset_chunk, it is used to save the
      reconf request chunk, so that it can be retransmitted, and to check if
      the response is really for this request by comparing the information
      inside with the response chunk as well.

       them when checking the fast path.
      -Killed tb->num_owners as per Eric's request.
      -Attached a reproducer to the bottom of this email.
      
      V1->V2:
      -Added a new patch 'inet: collapse ipv4/v6 rcv_saddr_equal functions into one'
       at Hannes' suggestion.
      -Dropped ->bind_conflict and just use the new helper.
      -Fixed a compile bug from the original ->bind_conflict patch.
      
      The original description of the series follows:
      
      At some point recently the guys working on our load balancer added the ability
      to use SO_REUSEPORT.  When they restarted their app with this option enabled
      they immediately hit a softlockup on what appeared to be the
      inet_bind_bucket->lock.  Eventually what all of our debugging and discussion led
      us to was the fact that the application comes up without SO_REUSEPORT, shuts
      down which creates around 100k twsk's, and then comes up and tries to open a
      bunch of sockets using SO_REUSEPORT, which meant traversing the inet_bind_bucket
      owners list under the lock.  Since this lock is needed for dealing with the
      twsk's and basically anything else related to connections we would softlockup,
      and sometimes not ever recover.
      
      To solve this problem I did what you see in Path 5/5.  Once we have a
      SO_REUSEPORT socket on the tb->owners list we know that the socket has no
      conflicts with any of the other sockets on that list.  So we can add a copy of
      the sock_common (really all we need is the recv_saddr but it seemed ugly to copy
      just the ipv6, ipv4, and flag to indicate if we were ipv6 only in there so I've
      copied the whole common) in order to check subsequent SO_REUSEPORT sockets.  If
      they match the previous one then we can skip the expensive
      inet_csk_bind_conflict check.  This is what eliminated the soft lockup that we
      were seeing.
      
      Patches 1-4 are cleanups and re-workings.  For instance when we specify port ==
      0 we need to find an open port, but we would do two passes through
      inet_csk_bind_conflict every time we found a possible port.  We would also keep
      track of the smallest_port value in order to try and use it if we found no
      port our first run through.  This however made no sense as it would have had to
      fail the first pass through inet_csk_bind_conflict, so would not actually pass
      the second pass through either.  Finally I split the function into two functions
      in order to make it easier to read and to distinguish between the two behaviors.
      
      I have tested this on one of our load balancing boxes during peak traffic and it
      hasn't fallen over.  But this is not my area, so obviously feel free to point
      out where I'm being stupid and I'll get it fixed up and retested.  Thanks,

      inet: reset tb->fastreuseport when adding a reuseport sk · 637bc8bb
      Josef Bacik authored
      
      
      If we have non reuseport sockets on a tb we will set tb->fastreuseport to 0 and
      never set it again.  Which means that in the future if we end up adding a bunch
      of reuseport sk's to that tb we'll have to do the expensive scan every time.
      Instead add the ipv4/ipv6 saddr fields to the bind bucket, as well as the family
      so we know what comparison to make, and the ipv6 only setting so we can make
      sure to compare with new sockets appropriately.  Once one sk has made it onto
      the list we know that there are no potential bind conflicts on the owners list
      that match that sk's rcv_addr.  So copy the sk's information into our bind
      bucket and set tb->fastruseport to FASTREUSESOCK_STRICT so we know we have to do
      an extra check for subsequent reuseport sockets and skip the expensive bind
      conflict check.

      inet: split inet_csk_get_port into two functions · 289141b7
      Josef Bacik authored
      
      
      inet_csk_get_port does two different things, it either scans for an open port,
      or it tries to see if the specified port is available for use.  Since these two
      operations have different rules and are basically independent lets split them
      into two different functions to make them both more readable.

      inet: don't check for bind conflicts twice when searching for a port · 6cd66616
      Josef Bacik authored
      
      
      This is just wasted time, we've already found a tb that doesn't have a bind
      conflict, and we don't drop the head lock so scanning again isn't going to give
      us a different answer.  Instead move the tb->reuse setting logic outside of the
      found_tb path and put it in the success: path.  Then make it so that we don't
      goto again if we find a bind conflict in the found_tb path as we won't reach
      this anymore when we are scanning for an ephemeral port.

      inet: kill smallest_size and smallest_port · b9470c27
      Josef Bacik authored
      
      
      In inet_csk_get_port we seem to be using smallest_port to figure out where the
      best place to look for a SO_REUSEPORT sk that matches with an existing set of
      SO_REUSEPORT's.  However if we get to the logic
      
      if (smallest_size != -1) {
      	port = smallest_port;
      	goto have_port;
      }
      
      we will do a useless search, because we would have already done the
      inet_csk_bind_conflict for that port and it would have returned 1, otherwise we
      would have gone to found_tb and succeeded.  Since this logic makes us do yet
      another trip through inet_csk_bind_conflict for a port we know won't work just
      delete this code and save us the time.

      The only difference between inet6_csk_bind_conflict and inet_csk_bind_conflict
      is how they check the rcv_saddr, so delete this call back and simply
      change inet_csk_bind_conflict to call inet_rcv_saddr_equal.

      We pass these per-protocol equal functions around in various places, but
      we can just have one function that checks the sk->sk_family and then do
      the right comparison function.  I've also changed the ipv4 version to
      not cast to inet_sock since it is unneeded.

      stmicro: add more information to Kconfig · ab70e586
      jpinto authored
      This patch adds more info to stmicro' Kconfig files in order to be clearer
      that the driver can be used by ethernet cards based on 10/100/1000/EQOS
      Synopsys IP Cores.
      
      EQOS was also added stmmac/Kconfig Kconfig, since dwmac4 is in fact EQoS,
      one of Synopsys Ethernet IPs. More info at:

      net/mlx5e: Support bpf_xdp_adjust_head() · d8bec2b2
      Martin KaFai Lau authored
      
      
      This patch adds bpf_xdp_adjust_head() support to mlx5e.
      
      1. rx_headroom is added to struct mlx5e_rq.  It uses
         an existing 4 byte hole in the struct.
      2. The adjusted data length is checked against
         MLX5E_XDP_MIN_INLINE and MLX5E_SW2HW_MTU(rq->netdev->mtu).
      3. The macro MLX5E_SW2HW_MTU is moved from en_main.c to en.h.
         MLX5E_HW2SW_MTU is also moved to en.h for symmetric reason
         but it is not a must.
      
      v2:
      - Keep the xdp specific logic in mlx5e_xdp_handle()
      - Update dma_len after the sanity checks in mlx5e_xmit_xdp_frame()
