      net/sched: avoid double free on matchall reoffload · 5f058368
      Pieter Jansen van Vuuren authored
      Avoid freeing cls_mall.rule twice when failing to setup flow_action
      offload used in the hardware intermediate representation. This is
      achieved by returning 0 when the setup fails but the skip software
      flag has not been set.

      nfp: reintroduce ndo_get_port_parent_id for representor ports · 1e966763
      Pieter Jansen van Vuuren authored
      NFP does not register devlink ports for representors (without
      the "devlink: expose PF and VF representors as ports" series
      there are no port flavours to expose them as).
      
      Commit c25f08ac ("nfp: remove ndo_get_port_parent_id implementation")
      went to far in removing ndo_get_port_parent_id for representors.
      This causes redirection offloads to fail, and switch_id attribute
      missing.
      
      Reintroduce the ndo_get_port_parent_id callback for representor ports.

      ====================
      net: phy: realtek: Fix RGMII TX/RX-delays initial config of rtl8211(e|f)
      
      It has been discovered that RX/TX delays of rtl8211e ethernet PHY
      can be configured via a MDIO register hidden in the extension pages
      layout. Particularly the extension page 0xa4 provides a register 0x1c,
      which bits 1 and 2 control the described delays. They are used to
      implement the "rgmii-{id,rxid,txid}" phy-mode support in patch 1.
      
      The second patch makes sure the rtl8211f TX-delay is configured only
      if RGMII interface mode is specified including the rgmii-rxid one.
      In other cases (most importantly for NA mode) the delays are supposed
      to be preconfigured by some other software or hardware and should be
      left as is without any modification. The similar thing is also done
      for rtl8211e in the patch 1 of this series.
      
      Changelog v3
      - Add this cover-letter.
      - Add Andrew' Reviewed-by tag to patch 1.
      - Accept RGMII_RXID interface mode for rtl8211f and clear the TX_DELAY
        bit in this case.
      - Initialize ret variable with 0 to prevent the "may be used uninitialized"
        warning in patch 1.
      
      Changelog v4
      - Rebase onto net-next

      net: phy: realtek: Change TX-delay setting for RGMII modes only · 1da7756e
      Serge Semin authored
      It's prone to problems if delay is cleared out for other than RGMII
      modes. So lets set/clear the TX-delay in the config register only
      if actually RGMII-like interface mode is requested. This only
      concerns rtl8211f chips.

      net: phy: realtek: Add rtl8211e rx/tx delays config · f81dadbc
      Serge Semin authored
      There are two chip pins named TXDLY and RXDLY which actually adds the 2ns
      delays to TXC and RXC for TXD/RXD latching. Alas this is the only
      documented info regarding the RGMII timing control configurations the PHY
      provides. It turns out the same settings can be setup via MDIO registers
      hidden in the extension pages layout. Particularly the extension page 0xa4
      provides a register 0x1c, which bits 1 and 2 control the described delays.
      They are used to implement the "rgmii-{id,rxid,txid}" phy-mode.
      
      The hidden RGMII configs register utilization was found in the rtl8211e
      U-boot driver:
      https://elixir.bootlin.com/u-boot/v2019.01/source/drivers/net/phy/realtek.c#L99
      
      There is also a freebsd-folks discussion regarding this register:
      https://reviews.freebsd.org/D13591
      
      It confirms that the register bits field must control the so called
      configuration pins described in the table 12-13 of the official PHY
      datasheet:
      8:6 = PHY Address
      5:4 = Auto-Negotiation
      3 = Interface Mode Select
      2 = RX Delay
      1 = TX Delay
      0 = SELRGV

      net: dsa: sja1105: fix check on while loop exit · 5425711b
      Colin Ian King authored
      The while-loop exit condition check is not correct; the
      loop should continue if the returns from the function calls are
      negative or the CRC status returns are invalid.  Currently it
      is ignoring the returns from the function calls.  Fix this by
      removing the status return checks and only break from the loop
      at the very end when we know that all the success condtions have
      been met.
      
      Kudos to Dan Carpenter for describing the correct fix and
      Vladimir Oltean for noting the change to the check on the number
      of retries.

      calling connect(AF_UNSPEC) on an already connected TCP socket is an
      established way to disconnect() such socket. After commit 68741a8a
      ("selinux: Fix ltp test connect-syscall failure") it no longer works
      and, in the above scenario connect() fails with EAFNOSUPPORT.
      
      Fix the above falling back to the generic/old code when the address family
      is not AF_INET{4,6}, but leave the SCTP code path untouched, as it has
      specific constraints.

      fib_rules: return 0 directly if an exactly same rule exists when NLM_F_EXCL not supplied · e9919a24

      With commit 153380ec ("fib_rules: Added NLM_F_EXCL support to

      only works with iproute2. For other tools like libnl, NetworkManager,
      it still could add duplicate rules with only NLM_F_CREATE flag, like
      
      [localhost ~ ]# ip rule
      0:      from all lookup local
      32766:  from all lookup main
      32767:  from all lookup default

      100000: from 192.168.7.5 lookup 5
      
      As it doesn't make sense to create two duplicate rules, let's just return
      0 if the rule exists.

      Pull AFS updates from David Howells:
       "A set of fix and development patches for AFS for 5.2.
      
        Summary:
      
         - Fix the AFS file locking so that sqlite can run on an AFS mount and
           also so that firefox and gnome can use a homedir that's mounted
           through AFS.
      
           This required emulation of fine-grained locking when the server
           will only support whole-file locks and no upgrade/downgrade. Four
           modes are provided, settable by mount parameter:
      
             "flock=local"   - No reference to the server
      
             "flock=openafs" - Fine-grained locks are local-only, whole-file
                               locks require sufficient server locks
      
             "flock=strict"  - All locks require sufficient server locks
      
             "flock=write"   - Always get an exclusive server lock
      
           If the volume is a read-only or backup volume, then flock=local for
           that volume.
      
         - Log extra information for a couple of cases where the client mucks
           up somehow: AFS vnode with undefined type and dir check failure -
           in both cases we seem to end up with unfilled data, but the issues
           happen infrequently and are difficult to reproduce at will.
      
         - Implement silly rename for unlink() and rename().
      
         - Set i_blocks so that du can get some information about usage.
      
         - Fix xattr handlers to return the right amount of data and to not
           overflow buffers.
      
         - Implement getting/setting raw AFS and YFS ACLs as xattrs"

           proper syscall auditing for all arches, and everyone else seemed to
