      net: fix installing orphaned programs · aefc3e72
      Jakub Kicinski authored
      When netdevice with offloaded BPF programs is destroyed
      the programs are orphaned and removed from the program
      IDA - their IDs get released (the programs may remain
      accessible via existing open file descriptors and pinned
      files). After IDs are released they are set to 0.
      
      This confuses dev_change_xdp_fd() because it compares
      the __dev_xdp_query() result where 0 means no program
      with prog->aux->id where 0 means orphaned.
      
      dev_change_xdp_fd() would have incorrectly returned success
      even though it had not installed the program.
      
      Since drivers already catch this case via bpf_offload_dev_match()
      let them handle this case. The error message drivers produce in
      this case ("program loaded for a different device") is in fact
      correct as the orphaned program must had to be loaded for a
      different device.

      r8169: fix wrong PHY ID issue with RTL8168dp · 62bdc8fd
      Heiner Kallweit authored
      As reported in [0] at least one RTL8168dp version has problems
      establishing a link. This chip version has an integrated RTL8211b PHY,
      however the chip seems to report a wrong PHY ID, resulting in a wrong
      PHY driver (for Generic Realtek PHY) being loaded.
      Work around this issue by adding a hook to r8168dp_2_mdio_read()
      for returning the correct PHY ID.

      Florian Fainelli authored
      Since it became possible for the DSA core to use a CPU port different
      than 8, our bcm_sf2_imp_setup() function was broken because it assumes
      that registers are applicable to port 8. In particular, the port's MAC
      is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS
      bits if we are not configured for port 8.

      inet: stop leaking jiffies on the wire · a904a069
      Eric Dumazet authored
      Historically linux tried to stick to RFC 791, 1122, 2003
      for IPv4 ID field generation.
      
      RFC 6864 made clear that no matter how hard we try,
      we can not ensure unicity of IP ID within maximum
      lifetime for all datagrams with a given source
      address/destination address/protocol tuple.
      
      Linux uses a per socket inet generator (inet_id), initialized
      at connection startup with a XOR of 'jiffies' and other
      fields that appear clear on the wire.
      
      Thiemo Nagel pointed that this strategy is a privacy
      concern as this provides 16 bits of entropy to fingerprint
      devices.
      
      Let's switch to a random starting point, this is just as
      good as far as RFC 6864 is concerned and does not leak
      anything critical.

      Intel Wired LAN Driver Updates 2019-11-01
      
      This series contains updates to e1000, igb, igc, ixgbe, i40e and driver
      documentation.
      
      Lyude Paul fixes an issue where a fatal read error occurs when the
      device is unplugged from the machine.  So change the read error into a
      warn while the device is still present.
      
      Manfred Rudigier found that the i350 device was not apart of the "Media
      Auto Sense" feature, yet the device supports it.  So add the missing
      i350 device to the check and fix an issue where the media auto sense
      would flip/flop when no cable was connected to the port causing spurious
      kernel log messages.
      
      I fixed an issue where the fix to resolve receive buffer starvation was
      applied in more than one place in the driver, one being the incorrect
      location in the i40e driver.
      
      Wenwen Wang fixes a potential memory leak in e1000 where allocated
      memory is not properly cleaned up in one of the error paths.
      
      Jonathan Neuschäfer cleans up the driver documentation to be consistent
      and remove the footnote reference, since the footnote no longer exists in
      the documentation.
      
      Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear
      it twice.
      
      v2: Fixed alignment issue in patch 3 of the series based on community

      At least on the i350 there is an annoying behavior that is maybe also

      widely used.
      
      If no cable is connected on both fiber/copper ports the media auto sense
      code will constantly swap between them as part of the watchdog task and
      produce many unnecessary kernel log messages.
      
      The swap code responsible for this behavior (switching to fiber) should
      not be executed if the current media type is copper and there is no signal
      detected on the fiber port. In this case we can safely wait until the
      AUTOSENSE_EN bit is cleared.

       "These are almost exclusively related to CPU errata in CPUs from
        Broadcom and Qualcomm where the workarounds were either not being
        enabled when they should have been or enabled when they shouldn't have
        been.
      
        The only "interesting" fix is ensuring that writeable, shared mappings
        are initially mapped as clean since we inadvertently broke the logic
        back in v4.14 and then noticed the problem via code inspection the
        other day.
      
        The only critical issue we have outstanding is a sporadic NULL
        dereference in the scheduler, which doesn't appear to be
        arm64-specific and PeterZ is tearing his hair out over it at the
        moment.
