      net: mvneta: fix the remaining Rx descriptor unmapping issues · f4a51879
      Antoine Tenart authored
      With CONFIG_DMA_API_DEBUG enabled we get DMA unmapping warning in
      various places of the mvneta driver, for example when putting down an
      interface while traffic is passing through.
      
      The issue is when using s/w buffer management, the Rx buffers are mapped
      using dma_map_page but unmapped with dma_unmap_single. This patch fixes
      this by using the right unmapping function.

      mpls: allow routes on ip6gre devices · d8e2262a
      Saif Hasan authored
      Summary:
      
      This appears to be necessary and sufficient change to enable `MPLS` on
      `ip6gre` tunnels (RFC4023).
      
      This diff allows IP6GRE devices to be recognized by MPLS kernel module
      and hence user can configure interface to accept packets with mpls
      headers as well setup mpls routes on them.
      
      Test Plan:
      
      Test plan consists of multiple containers connected via GRE-V6 tunnel.
      Then carrying out testing steps as below.
      
      - Carry out necessary sysctl settings on all containers
      
      ```
      sysctl -w net.mpls.platform_labels=65536
      sysctl -w net.mpls.ip_ttl_propagate=1
      sysctl -w net.mpls.conf.lo.input=1
      ```
      
      - Establish IP6GRE tunnels
      
      ```
      ip -6 tunnel add name if_1_2_1 mode ip6gre \
        local 2401:db00:21:6048:feed:0::1 \
        remote 2401:db00:21:6048:feed:0::2 key 1
      ip link set dev if_1_2_1 up
      sysctl -w net.mpls.conf.if_1_2_1.input=1
      ip -4 addr add 169.254.0.2/31 dev if_1_2_1 scope link
      
      ip -6 tunnel add name if_1_3_1 mode ip6gre \
        local 2401:db00:21:6048:feed:0::1 \
        remote 2401:db00:21:6048:feed:0::3 key 1
      ip link set dev if_1_3_1 up
      sysctl -w net.mpls.conf.if_1_3_1.input=1
      ip -4 addr add 169.254.0.4/31 dev if_1_3_1 scope link
      ```
      
      - Install MPLS encap rules on node-1 towards node-2
      
      ```
      ip route add 192.168.0.11/32 nexthop encap mpls 32/64 \
        via inet 169.254.0.3 dev if_1_2_1
      ```
      
      - Install MPLS forwarding rules on node-2 and node-3
      ```
      // node2
      ip -f mpls route add 32 via inet 169.254.0.7 dev if_2_4_1
      
      // node3
      ip -f mpls route add 64 via inet 169.254.0.12 dev if_4_3_1
      ```
      
      - Ping 192.168.0.11 (node4) from 192.168.0.1 (node1) (where routing
        towards 192.168.0.1 is via IP route directly towards node1 from node4)
      ```
      ping 192.168.0.11
      ```
      
      - tcpdump on interface to capture ping packets wrapped within MPLS
        header which inturn wrapped within IP6GRE header
      
      ```

      net: aquantia: memory corruption on jumbo frames · d26ed6b0
      Friedemann Gerold authored
      This patch fixes skb_shared area, which will be corrupted
      upon reception of 4K jumbo packets.
      
      Originally build_skb usage purpose was to reuse page for skb to eliminate
      needs of extra fragments. But that logic does not take into account that
      skb_shared_info should be reserved at the end of skb data area.
      
      In case packet data consumes all the page (4K), skb_shinfo location
      overflows the page. As a consequence, __build_skb zeroed shinfo data above
      the allocated page, corrupting next page.
      
      The issue is rarely seen in real life because jumbo are normally larger
      than 4K and that causes another code path to trigger.
      But it 100% reproducible with simple scapy packet, like:
      
          sendp(IP(dst="192.168.100.3") / TCP(dport=443) \
                / Raw(RandString(size=(4096-40))), iface="enp1s0")

      ====================
      netpoll: avoid capture effects for NAPI drivers
      
      As diagnosed by Song Liu, ndo_poll_controller() can
      be very dangerous on loaded hosts, since the cpu
      calling ndo_poll_controller() might steal all NAPI
      contexts (for all RX/TX queues of the NIC).
      
      This capture, showing one ksoftirqd eating all cycles
      can last for unlimited amount of time, since one
      cpu is generally not able to drain all the queues under load.
      
      It seems that all networking drivers that do use NAPI
      for their TX completions, should not provide a ndo_poll_controller() :
      
      Most NAPI drivers have netpoll support already handled
      in core networking stack, since netpoll_poll_dev()
      uses poll_napi(dev) to iterate through registered
      NAPI contexts for a device.
      
      This patch series take care of the first round, we will
      handle other drivers in future rounds.

      igb: remove ndo_poll_controller · 0542997e
      Eric Dumazet authored
      As diagnosed by Song Liu, ndo_poll_controller() can
      be very dangerous on loaded hosts, since the cpu
      calling ndo_poll_controller() might steal all NAPI
      contexts (for all RX/TX queues of the NIC). This capture
      can last for unlimited amount of time, since one
      cpu is generally not able to drain all the queues under load.
      
      igb uses NAPI for TX completions, so we better let core
      networking stack call the napi->poll() to avoid the capture.

      This also removes a problematic use of disable_irq() in
      a context it is forbidden, as explained in commit
      af3e0fcf ("8139too: Use disable_irq_nosync() in
      rtl8139_poll_controller()")

      bonding: use netpoll_poll_dev() helper · 93f62ad5
      Eric Dumazet authored
      We want to allow NAPI drivers to no longer provide
      ndo_poll_controller() method, as it has been proven problematic.
      
      team driver must not look at its presence, but instead call
      netpoll_poll_dev() which factorize the needed actions.

      netpoll: make ndo_poll_controller() optional · ac3d9dd0
      Eric Dumazet authored
      As diagnosed by Song Liu, ndo_poll_controller() can
      be very dangerous on loaded hosts, since the cpu
      calling ndo_poll_controller() might steal all NAPI
      contexts (for all RX/TX queues of the NIC). This capture
      can last for unlimited amount of time, since one
      cpu is generally not able to drain all the queues under load.
      
      It seems that all networking drivers that do use NAPI
      for their TX completions, should not provide a ndo_poll_controller().
      
      NAPI drivers have netpoll support already handled
      in core networking stack, since netpoll_poll_dev()
      uses poll_napi(dev) to iterate through registered
      NAPI contexts for a device.
      
      This patch allows netpoll_poll_dev() to process NAPI
      contexts even for drivers not providing ndo_poll_controller(),
      allowing for following patches in NAPI drivers.
      
      Also we export netpoll_poll_dev() so that it can be called
      by bonding/team drivers in following patches.
