      of_mdio / mdiobus: ensure mdio devices have fwnode correctly populated · 94a5ef1b
      Russell King authored
      Ensure that all mdio devices populate the struct device fwnode pointer
      as well as the of_node pointer to allow drivers that wish to use
      fwnode APIs to work.

      net: phy: fix resume handling · f5e64032
      Russell King authored
      When a PHY has the BMCR_PDOWN bit set, it may decide to ignore writes
      to other registers, or reset the registers to power-on defaults.
      Micrel PHYs do this for their interrupt registers.
      
      The current structure of phylib tries to enable interrupts before
      resuming (and releasing) the BMCR_PDOWN bit.  This fails, causing
      Micrel PHYs to stop working after a suspend/resume sequence if they
      are using interrupts.
      
      Fix this by ensuring that the PHY driver resume methods do not take
      the phydev->lock mutex themselves, but the callers of phy_resume()
      take that lock.  This then allows us to move the call to phy_resume()
      before we enable interrupts in phy_start().

      ARM: dts: vf610-zii-dev: use XAUI for DSA link ports · cd8165c3
      Russell King authored
      Use XAUI rather than XGMII for DSA link ports, as this is the interface
      mode that the switches actually use. XAUI is the 4 lane bus with clock
      per direction, whereas XGMII is a 32 bit bus with clock.

      net: dsa: allow XAUI phy interface mode · 2e51a8dc
      Russell King authored
      XGMII is a 32-bit bus plus two clock signals per direction.  XAUI is
      four serial lanes per direction.  The 88e6190 supports XAUI but not
      XGMII as it doesn't have enough pins.  The same is true of 88e6176.
      
      Match on PHY_INTERFACE_MODE_XAUI for the XAUI port type, but keep
      accepting XGMII for backwards compatibility.

      hippi: Fix a Fix a possible sleep-in-atomic bug in rr_close · 6e266610
      Jia-Ju Bai authored
      The driver may sleep under a spinlock.
      The function call path is:
      rr_close (acquire the spinlock)
        free_irq --> may sleep
      
      To fix it, free_irq is moved to the place without holding the spinlock.
      
      This bug is found by my static analysis tool(DSAC) and checked by my code review.

      Netfilter fixes for net
      
      The follow patchset contains Netfilter fixes for your net tree,
      they are:
      
      1) Fix compilation warning in x_tables with clang due to useless
         redundant reassignment, from Colin Ian King.
      
      2) Add bugtrap to net_exit to catch uninitialized lists, patch
         from Vasily Averin.
      
      3) Fix out of bounds memory reads in H323 conntrack helper, this
         comes with an initial patch to remove replace the obscure
         CHECK_BOUND macro as a dependency. From Eric Sesterhenn.
      
      4) Reduce retransmission timeout when window is 0 in TCP conntrack,
         from Florian Westphal.
      
      6) ctnetlink clamp timeout to INT_MAX if timeout is too large,
         otherwise timeout wraps around and it results in killing the
         entry that is being added immediately.
      
      7) Missing CAP_NET_ADMIN checks in cthelper and xt_osf, due to
         no netns support. From Kevin Cernekee.
      
      8) Missing maximum number of instructions checks in xt_bpf, patch
         from Jann Horn.
      
      9) With no CONFIG_PROC_FS ipt_CLUSTERIP compilation breaks,
         patch from Arnd Bergmann.
      
      10) Missing netlink attribute policy in nftables exthdr, from
          Florian Westphal.
      
      11) Enable conntrack with IPv6 MASQUERADE rules, as a357b3f8
          should have done in first place, from Konstantin Khlebnikov.

      net: igmp: Use correct source address on IGMPv3 reports · a46182b0
      Kevin Cernekee authored
      Closing a multicast socket after the final IPv4 address is deleted
      from an interface can generate a membership report that uses the
      source IP from a different interface.  The following test script, run
      from an isolated netns, reproduces the issue:
      
          #!/bin/bash
      
          ip link add dummy0 type dummy
          ip link add dummy1 type dummy
          ip link set dummy0 up
          ip link set dummy1 up
          ip addr add 10.1.1.1/24 dev dummy0
          ip addr add 192.168.99.99/24 dev dummy1
      
          tcpdump -U -i dummy0 &
          socat EXEC:"sleep 2" \
              UDP4-DATAGRAM:239.101.1.68:8889,ip-add-membership=239.0.1.68:10.1.1.1 &
      
          sleep 1
          ip addr del 10.1.1.1/24 dev dummy0
          sleep 5
          kill %tcpdump
      
      RFC 3376 specifies that the report must be sent with a valid IP source
      address from the destination subnet, or from address 0.0.0.0.  Add an
      extra check to make sure this is the case.

      Fix this by reading device mtu once and checking IPv4 minimal MTU.

      tcp md5sig: Use skb's saddr when replying to an incoming segment · 30791ac4
      Christoph Paasch authored
      The MD5-key that belongs to a connection is identified by the peer's
      IP-address. When we are in tcp_v4(6)_reqsk_send_ack(), we are replying
      to an incoming segment from tcp_check_req() that failed the seq-number
      checks.
      
      Thus, to find the correct key, we need to use the skb's saddr and not
      the daddr.
      
      This bug seems to have been there since quite a while, but probably got
      unnoticed because the consequences are not catastrophic. We will call
      tcp_v4_reqsk_send_ack only to send a challenge-ACK back to the peer,
      thus the connection doesn't really fail.

       "A series of fixes for the media subsytem:
      
         - The largest amount of fixes in this series is with regards to
           comments that aren't kernel-doc, but start with "/**".
      
           A new check added for 4.15 makes it to produce a *huge* amount of
           new warnings (I'm compiling here with W=1). Most of the patches in
           this series fix those.
      
           No code changes - just comment changes at the source files
      
         - rc: some fixed in order to better handle RC repetition codes
      
         - v4l-async: use the v4l2_dev from the root notifier when matching
           sub-devices
      
         - v4l2-fwnode: Check subdev count after checking port
      
         - ov 13858 and et8ek8: compilation fix with randconfigs
      
         - usbtv: a trivial new USB ID addition

      this is a pull request of 6 patches for net/master.
      
      Martin Kelly provides 5 patches for various USB based CAN drivers, that
      properly cancel the URBs on adapter unplug, so that the driver doesn't
      end up in an endless loop. Stephane Grosjean provides a patch to restart
      the tx queue if zero length packages are transmitted.

      net: mvpp2: fix the RSS table entry offset · 8a7b741e
      Antoine Tenart authored
      The macro used to access or set an RSS table entry was using an offset
      of 8, while it should use an offset of 0. This lead to wrongly configure
      the RSS table, not accessing the right entries.

      tcp: evaluate packet losses upon RTT change · 6065fd0d
      Yuchung Cheng authored
      RACK skips an ACK unless it advances the most recently delivered
      TX timestamp (rack.mstamp). Since RACK also uses the most recent
      RTT to decide if a packet is lost, RACK should still run the
      loss detection whenever the most recent RTT changes. For example,
      an ACK that does not advance the timestamp but triggers the cwnd
      undo due to reordering, would then use the most recent (higher)
      RTT measurement to detect further losses.
