      ====================
      Intel Wired LAN Driver Updates 2018-04-24
      
      This series contains fixes to ixgbevf, igb and ice drivers.
      
      Colin Ian King fixes the return value on error for the new XDP support
      that went into ixgbevf for 4.17.
      
      Vinicius provides a fix for queue 0 for igb, which was not receiving all
      the credits it needed when QAV mode was enabled.
      
      Anirudh provides several fixes for the new ice driver, starting with
      properly initializing num_nodes_added to zero.  Fixed up a code comment
      to better reflect what is really going on in the code.  Fixed how to
      detect if an OICR interrupt has occurred to a more reliable method.
      
      Md Fahad fixes the ice driver to allocate the right amount of memory
      when reading and storing the devices MAC addresses.  The device can have
      up to 2 MAC addresses (LAN and WoL), while WoL is currently not
      supported, we need to ensure it can be properly handled when support is
      added.

      For the MAC read operation, the device can return up to two (LAN and WoL)
      MAC addresses. Without access to adequate memory, the device will return
      an error. Fixed this by allocating the right amount of memory. Also, logic
      to detect and copy the LAN MAC address into the port_info structure has
      been added. Note that the WoL MAC address is ignored currently as the WoL
      feature isn't supported yet.

      ====================
      ipconfig: NTP server support, bug fixes, documentation improvements
      
      This series (against net-next) makes various improvements to ipconfig:
      
       - Patch #1 correctly documents the behaviour of parameter 4 in the
         "ip=" and "nfsaddrs=" command line parameter.
       - Patch #2 tidies up the printk()s for reporting configured name
         servers.
       - Patch #3 fixes a bug in autoconfiguration via BOOTP whereby the IP
         addresses of IEN-116 name servers are requested from the BOOTP
         server, rather than those of DNS name servers.
       - Patch #4 requests the number of DNS servers specified by
         CONF_NAMESERVERS_MAX when autoconfiguring via BOOTP, rather than
         hardcoding it to 2.
       - Patch #5 fully documents the contents and format of /proc/net/pnp in
         Documentation/filesystems/nfs/nfsroot.txt.
       - Patch #6 fixes a bug whereby bogus information is written to
         /proc/net/pnp when ipconfig is not used.
       - Patch #7 creates a new procfs directory for ipconfig-related
         configuration reports at /proc/net/ipconfig.
       - Patch #8 allows for NTP servers to be configured (manually on the
         kernel command line or automatically via DHCP), enabling systems with
         an NFS root filesystem to synchronise their clock before mounting
         their root filesystem. NTP server IP addresses are written to
         /proc/net/ipconfig/ntp_servers.
      
      Changes from v1:
      
       - David requested that a new directory /proc/net/ipconfig be created to
         contain ipconfig-related configuration reports, which is implemented
         in the new patch #7. NTP server IPs are now written to this directory
         instead of /proc/net/ntp in the new patch #8.
       - Cong and David both requested that the modification to CREDITS be
         dropped. This patch has been removed from the series.

      ipconfig: Write NTP server IPs to /proc/net/ipconfig/ntp_servers · c04d2cb2
      Chris Novakovic authored
      Distributed filesystems are most effective when the server and client
      clocks are synchronised. Embedded devices often use NFS for their
      root filesystem but typically do not contain an RTC, so the clocks of
      the NFS server and the embedded device will be out-of-sync when the root
      filesystem is mounted (and may not be synchronised until late in the
      boot process).
      
      Extend ipconfig with the ability to export IP addresses of NTP servers
      it discovers to /proc/net/ipconfig/ntp_servers. They can be supplied as
      follows:
      
       - If ipconfig is configured manually via the "ip=" or "nfsaddrs="
         kernel command line parameters, one NTP server can be specified in
         the new "<ntp0-ip>" parameter.
       - If ipconfig is autoconfigured via DHCP, request DHCP option 42 in
         the DHCPDISCOVER message, and record the IP addresses of up to three
         NTP servers sent by the responding DHCP server in the subsequent
         DHCPOFFER message.
      
      ipconfig will only write the NTP server IP addresses it discovers to
      /proc/net/ipconfig/ntp_servers, one per line (in the order received from
      the DHCP server, if DHCP autoconfiguration is used); making use of these
      NTP servers is the responsibility of a user space process (e.g. an
      initrd/initram script that invokes an NTP client before mounting an NFS
      root filesystem).

      ipconfig: Correctly initialise ic_nameservers · 300eec7c
      Chris Novakovic authored
      ic_nameservers, which stores the list of name servers discovered by
      ipconfig, is initialised (i.e. has all of its elements set to NONE, or
      0xffffffff) by ic_nameservers_predef() in the following scenarios:
      
       - before the "ip=" and "nfsaddrs=" kernel command line parameters are
         parsed (in ip_auto_config_setup());
       - before autoconfiguring via DHCP or BOOTP (in ic_bootp_init()), in
         order to clear any values that may have been set after parsing "ip="
         or "nfsaddrs=" and are no longer needed.
      
      This means that ic_nameservers_predef() is not called when neither "ip="
      nor "nfsaddrs=" is specified on the kernel command line. In this
      scenario, every element in ic_nameservers remains set to 0x00000000,
      which is indistinguishable from ANY and causes pnp_seq_show() to write
      the following (bogus) information to /proc/net/pnp:
      
        #MANUAL
        nameserver 0.0.0.0
        nameserver 0.0.0.0
        nameserver 0.0.0.0
      
      This is potentially problematic for systems that blindly link
      /etc/resolv.conf to /proc/net/pnp.
      
      Ensure that ic_nameservers is also initialised when neither "ip=" nor
      "nfsaddrs=" are specified by calling ic_nameservers_predef() in
      ip_auto_config(), but only when ip_auto_config_setup() was not called
      earlier. This causes the following to be written to /proc/net/pnp, and
      is consistent with what gets written when ipconfig is configured
      manually but no name servers are specified on the kernel command line:

      ipconfig: BOOTP: Request CONF_NAMESERVERS_MAX name servers · de1fa15b
      Chris Novakovic authored
      When ipconfig is autoconfigured via BOOTP, the request packet
      initialised by ic_bootp_init_ext() always allocates 8 bytes for the name
      server option, limiting the BOOTP server to responding with at most 2
      name servers even though ipconfig in fact supports an arbitrary number
      of name servers (as defined by CONF_NAMESERVERS_MAX, which is currently
      3).
      
      Only request name servers in the request packet if CONF_NAMESERVERS_MAX
      is positive (to comply with [1, §3.8]), and allocate enough space in the
      packet for CONF_NAMESERVERS_MAX name servers to indicate the maximum
      number we can accept in response.

      ipconfig: BOOTP: Don't request IEN-116 name servers · 4e1a8af2
      Chris Novakovic authored
      When ipconfig is autoconfigured via BOOTP, the request packet
      initialised by ic_bootp_init_ext() allocates 8 bytes for tag 5 ("Name
      Server" [1, §3.7]), but tag 5 in the response isn't processed by
      ic_do_bootp_ext(). Instead, allocate the 8 bytes to tag 6 ("Domain Name
      Server" [1, §3.8]), which is processed by ic_do_bootp_ext(), and appears
      to have been the intended tag to request.
      
      This won't cause any breakage for existing users, as tag 5 responses
      provided by BOOTP servers weren't being processed anyway.

      ipconfig: Tidy up reporting of name servers · e18bdc83
      Chris Novakovic authored
      Commit 5e953778 ("ipconfig: add
      nameserver IPs to kernel-parameter ip=") adds the IP addresses of
      discovered name servers to the summary printed by ipconfig when
      configuration is complete. It appears the intention in ip_auto_config()
      was to print the name servers on a new line (especially given the
      spacing and lack of comma before "nameserver0="), but they're actually
      printed on the same line as the NFS root filesystem configuration
      summary:
      
        [    0.686186] IP-Config: Complete:
        [    0.686226]      device=eth0, hwaddr=xx:xx:xx:xx:xx:xx, ipaddr=10.0.0.2, mask=255.255.255.0, gw=10.0.0.1
        [    0.686328]      host=test, domain=example.com, nis-domain=(none)

      This makes it harder to read and parse ipconfig's output. Instead, print
      the name servers on a separate line:

      rhashtable: improve rhashtable_walk stability when stop/start used. · 5d240a89
      NeilBrown authored
      When a walk of an rhashtable is interrupted with rhastable_walk_stop()
      and then rhashtable_walk_start(), the location to restart from is based
      on a 'skip' count in the current hash chain, and this can be incorrect
      if insertions or deletions have happened.  This does not happen when
      the walk is not stopped and started as iter->p is a placeholder which
      is safe to use while holding the RCU read lock.
      
      In rhashtable_walk_start() we can revalidate that 'p' is still in the
      same hash chain.  If it isn't then the current method is still used.
      
      With this patch, if a rhashtable walker ensures that the current
      object remains in the table over a stop/start period (possibly by
      elevating the reference count if that is sufficient), it can be sure
      that a walk will not miss objects that were in the hashtable for the
      whole time of the walk.
      
      rhashtable_walk_start() may not find the object even though it is
      still in the hashtable if a rehash has moved it to a new table.  In
      this case it will (eventually) get -EAGAIN and will need to proceed
      through the whole table again to be sure to see everything at least
      once.

      rhashtable: reset iter when rhashtable_walk_start sees new table · b41cc04b
      NeilBrown authored
      The documentation claims that when rhashtable_walk_start_check()
      detects a resize event, it will rewind back to the beginning
      of the table.  This is not true.  We need to set ->slot and
      ->skip to be zero for it to be true.

      rhashtable: Revise incorrect comment on r{hl, hash}table_walk_enter() · 82266e98
      NeilBrown authored
      Neither rhashtable_walk_enter() or rhltable_walk_enter() sleep, though
      they do take a spinlock without irq protection.
      So revise the comments to accurately state the contexts in which
      these functions can be called.

      Eric Dumazet authored
      RETPOLINE made calls to tp->af_specific->md5_lookup() quite expensive,
      given they have no result.
      We can omit the calls for sockets that have no md5 keys.

      packet: fix bitfield update race · a6361f0c
      Willem de Bruijn authored
      Updates to the bitfields in struct packet_sock are not atomic.
      Serialize these read-modify-write cycles.
      
      Move po->running into a separate variable. Its writes are protected by
      po->bind_lock (except for one startup case at packet_create). Also
      replace a textual precondition warning with lockdep annotation.
      
      All others are set only in packet_setsockopt. Serialize these
      updates by holding the socket lock. Analogous to other field updates,
      also hold the lock when testing whether a ring is active (pg_vec).

      ice: Do not check INTEVENT bit for OICR interrupts · 30d84397
      Ben Shelton authored
      According to the hardware spec, checking the INTEVENT bit isn't a
      reliable way to detect if an OICR interrupt has occurred. This is
      because this bit can be cleared by the hardware/firmware before the
      interrupt service routine has run. So instead, just check for OICR
      events every time.
