      net: phy: marvell: avoid pause mode on SGMII-to-Copper for 88e151x · 6623c0fb
      Russell King authored
      Observed on the 88e1512 in SGMII-to-Copper mode, negotiating pause
      is unreliable.  While the pause bits can be set in the advertisment
      register, they clear shortly after negotiation with a link partner
      commences irrespective of the cause of the negotiation.
      
      While these bits may be correctly conveyed to the link partner on the
      first negotiation, a subsequent negotiation (eg, due to negotiation
      restart by the link partner, or reconnection of the cable) will result
      in the link partner seeing these bits as zero, while the kernel
      believes that it has advertised pause modes.
      
      This leads to the local kernel evaluating (eg) symmetric pause mode,
      while the remote end evaluates that we have no pause mode capability.
      
      Since we can't guarantee the advertisment, disable pause mode support
      with this PHY when used in SGMII-to-Copper mode.
      
      The 88e1510 in RGMII-to-Copper mode appears to behave correctly.

      net: bridge: fix early call to br_stp_change_bridge_id and plug newlink leaks · 84aeb437
      Nikolay Aleksandrov authored
      The early call to br_stp_change_bridge_id in bridge's newlink can cause
      a memory leak if an error occurs during the newlink because the fdb
      entries are not cleaned up if a different lladdr was specified, also
      another minor issue is that it generates fdb notifications with
      ifindex = 0. Another unrelated memory leak is the bridge sysfs entries
      which get added on NETDEV_REGISTER event, but are not cleaned up in the
      newlink error path. To remove this special case the call to
      br_stp_change_bridge_id is done after netdev register and we cleanup the
      bridge on changelink error via br_dev_delete to plug all leaks.
      
      This patch makes netlink bridge destruction on newlink error the same as
      dellink and ioctl del which is necessary since at that point we have a
      fully initialized bridge device.
      
      To reproduce the issue:
      $ ip l add br0 address 00:11:22:33:44:55 type bridge group_fwd_mask 1

      sctp: fix the issue that a __u16 variable may overflow in sctp_ulpq_renege · 5c468674
      Xin Long authored
      Now when reneging events in sctp_ulpq_renege(), the variable freed
      could be increased by a __u16 value twice while freed is of __u16
      type. It means freed may overflow at the second addition.
      
      This patch is to fix it by using __u32 type for 'freed', while at
      it, also to remove 'if (chunk)' check, as all renege commands are
      generated in sctp_eat_data and it can't be NULL.

      net: qcom/emac: Change the order of mac up and sgmii open · ac3241d5
      Hemanth Puranik authored
      This patch fixes the order of mac_up and sgmii_open for the
      reasons noted below:
      
      - If open takes more time(if the SGMII block is not responding or
        if we want to do some delay based task) in this situation we
        will hit NETDEV watchdog
      - The main reason : We should signal to upper layers that we are
        ready to receive packets "only" when the entire path is initialized
        not the other way around, this is followed in the reset path where
        we do mac_down, sgmii_reset and mac_up. This also makes the driver
        uniform across the reset and open paths.
      - In the future there may be need for delay based tasks to be done in
        sgmii open which will result in NETDEV watchdog
      - As per the documentation the order of init should be sgmii, mac, rings
        and DMA

      tipc: remove leaving group member from all lists · 3f42f5fe
      Jon Maloy authored
      A group member going into state LEAVING should never go back to any
      other state before it is finally deleted. However, this might happen
      if the socket needs to send out a RECLAIM message during this interval.
      Since we forget to remove the leaving member from the group's 'active'
      or 'pending' list, the member might be selected for reclaiming, change
      state to RECLAIMING, and get stuck in this state instead of being
      deleted. This might lead to suppression of the expected 'member down'
      event to the receiver.
      
      We fix this by removing the member from all lists, except the RB tree,
      at the moment it goes into state LEAVING.

      tipc: fix lost member events bug · 23483399
      Jon Maloy authored
      Group messages are not supposed to be returned to sender when the
      destination socket disappears. This is done correctly for regular
      traffic messages, by setting the 'dest_droppable' bit in the header.
      But we forget to do that in group protocol messages. This has the effect
      that such messages may sometimes bounce back to the sender, be perceived
      as a legitimate peer message, and wreak general havoc for the rest of
      the session. In particular, we have seen that a member in state LEAVING
      may go back to state RECLAIMED or REMITTED, hence causing suppression
      of an otherwise expected 'member down' event to the user.
      
      We fix this by setting the 'dest_droppable' bit even in group protocol
      messages.

      vxlan: restore dev->mtu setting based on lower device · f870c1ff
      Alexey Kodanev authored
      Stefano Brivio says:
          Commit a985343b ("vxlan: refactor verification and
          application of configuration") introduced a change in the
          behaviour of initial MTU setting: earlier, the MTU for a link
          created on top of a given lower device, without an initial MTU
          specification, was set to the MTU of the lower device minus
          headroom as a result of this path in vxlan_dev_configure():
      
      	if (!conf->mtu)
      		dev->mtu = lowerdev->mtu -
      			   (use_ipv6 ? VXLAN6_HEADROOM : VXLAN_HEADROOM);
      
          which is now gone. Now, the initial MTU, in absence of a
          configured value, is simply set by ether_setup() to ETH_DATA_LEN
          (1500 bytes).
      
          This breaks userspace expectations in case the MTU of
          the lower device is higher than 1500 bytes minus headroom.
      
      This patch restores the previous behaviour on newlink operation. Since
      max_mtu can be negative and we update dev->mtu directly, also check it
      for valid minimum.

      ipv6: icmp6: Allow icmp messages to be looped back · 588753f1
      Brendan McGrath authored
      One example of when an ICMPv6 packet is required to be looped back is
      when a host acts as both a Multicast Listener and a Multicast Router.
      
      A Multicast Router will listen on address ff02::16 for MLDv2 messages.
      
      Currently, MLDv2 messages originating from a Multicast Listener running
      on the same host as the Multicast Router are not being delivered to the
      Multicast Router. This is due to dst.input being assigned the default
      value of dst_discard.
      
      This results in the packet being looped back but discarded before being
      delivered to the Multicast Router.
      
      This patch sets dst.input to ip6_input to ensure a looped back packet
      is delivered to the Multicast Router.

      Revert "mm: replace p??_write with pte_access_permitted in fault + gup paths" · f6f37321
      Linus Torvalds authored
      This reverts commits 5c9d2d5c, c7da82b8, and e7fe7b5c.
      
      We'll probably need to revisit this, but basically we should not
      complicate the get_user_pages_fast() case, and checking the actual page
      table protection key bits will require more care anyway, since the
      protection keys depend on the exact state of the VM in question.
      
      Particularly when doing a "remote" page lookup (ie in somebody elses VM,
      not your own), you need to be much more careful than this was.  Dave
      Hansen says:
      
       "So, the underlying bug here is that we now a get_user_pages_remote()
        and then go ahead and do the p*_access_permitted() checks against the
        current PKRU. This was introduced recently with the addition of the
        new p??_access_permitted() calls.
      
        We have checks in the VMA path for the "remote" gups and we avoid
        consulting PKRU for them. This got missed in the pkeys selftests
        because I did a ptrace read, but not a *write*. I also didn't
        explicitly test it against something where a COW needed to be done"
      
      It's also not entirely clear that it makes sense to check the protection
      key bits at this level at all.  But one possible eventual solution is to
      make the get_user_pages_fast() case just abort if it sees protection key
      bits set, which makes us fall back to the regular get_user_pages() case,
      which then has a vma and can do the check there if we want to.
      
      We'll see.
      
      Somewhat related to this all: what we _do_ want to do some day is to
      check the PAGE_USER bit - it should obviously always be set for user
      pages, but it would be a good check to have back.  Because we have no
      generic way to test for it, we lost it as part of moving over from the
      architecture-specific x86 GUP implementation to the generic one in
      commit e585513b ("x86/mm/gup: Switch GUP to the generic
      get_user_page_fast() implementation").

      net: qcom/emac: Reduce timeout for mdio read/write · 043ee1de
      Hemanth Puranik authored
      Currently mdio read/write takes around ~115us as the timeout
      between status check is set to 100us.
      By reducing the timeout to 1us mdio read/write takes ~15us to
      complete. This improves the link up event response.
