      Revert "netfilter: bridge: query conntrack about skb dnat" · faecbb45
      Florian Westphal authored
      This reverts commit c055d5b0.
      
      There are two issues:
      'dnat_took_place' made me think that this is related to
      -j DNAT/MASQUERADE.
      
      But thats only one part of the story.  This is also relevant for SNAT
      when we undo snat translation in reverse/reply direction.
      
      Furthermore, I originally wanted to do this mainly to avoid
      storing ipv6 addresses once we make DNAT/REDIRECT work
      for ipv6 on bridges.
      
      However, I forgot about SNPT/DNPT which is stateless.
      
      So we can't escape storing address for ipv6 anyway. Might as
      well do it for ipv4 too.

      netfilter: ensure number of counters is >0 in do_replace() · 1086bbe9
      Dave Jones authored
      After improving setsockopt() coverage in trinity, I started triggering
      vmalloc failures pretty reliably from this code path:
      
      warn_alloc_failed+0xe9/0x140
      __vmalloc_node_range+0x1be/0x270
      vzalloc+0x4b/0x50
      __do_replace+0x52/0x260 [ip_tables]
      do_ipt_set_ctl+0x15d/0x1d0 [ip_tables]
      nf_setsockopt+0x65/0x90
      ip_setsockopt+0x61/0xa0
      raw_setsockopt+0x16/0x60
      sock_common_setsockopt+0x14/0x20
      SyS_setsockopt+0x71/0xd0
      
      It turns out we don't validate that the num_counters field in the
      struct we pass in from userspace is initialized.
      
      The same problem also exists in ebtables, arptables, ipv6, and the
      compat variants.

      netfilter: nfnetlink_{log,queue}: Register pernet in first place · 3bfe0498
      Francesco Ruggeri authored
      nfnetlink_{log,queue}_init() register the netlink callback nf*_rcv_nl_event
      before registering the pernet_subsys, but the callback relies on data
      structures allocated by pernet init functions.
      
      When nfnetlink_{log,queue} is loaded, if a netlink message is received after
      the netlink callback is registered but before the pernet_subsys is registered,
      the kernel will panic in the sequence
      
      nfulnl_rcv_nl_event
        nfnl_log_pernet
          net_generic
            BUG_ON(id == 0)  where id is nfnl_log_net_id.
      
      The panic can be easily reproduced in 4.0.3 by:
      
      while true ;do modprobe nfnetlink_log ; rmmod nfnetlink_log ; done &
      while true ;do ip netns add dummy ; ip netns del dummy ; done &
      
      This patch moves register_pernet_subsys to earlier in nfnetlink_log_init.
      
      Notice that the BUG_ON hit in 4.0.3 was recently removed in 2591ffd3
      ["netns: remove BUG_ONs from net_generic()"].

      rhashtable: Add cap on number of elements in hash table · 07ee0722
      Herbert Xu authored
      We currently have no limit on the number of elements in a hash table.
      This is a problem because some users (tipc) set a ceiling on the
      maximum table size and when that is reached the hash table may
      degenerate.  Others may encounter OOM when growing and if we allow
      insertions when that happens the hash table perofrmance may also
      suffer.
      
      This patch adds a new paramater insecure_max_entries which becomes
      the cap on the table.  If unset it defaults to max_size * 2.  If
      it is also zero it means that there is no cap on the number of
      elements in the table.  However, the table will grow whenever the
      utilisation hits 100% and if that growth fails, you will get ENOMEM
      on insertion.
      
      As allowing oversubscription is potentially dangerous, the name
      contains the word insecure.
      
      Note that the cap is not a hard limit.  This is done for performance
      reasons as enforcing a hard limit will result in use of atomic ops
      that are heavier than the ones we currently use.
      
      The reasoning is that we're only guarding against a gross over-
      subscription of the table, rather than a small breach of the limit.

      net: phy: Make sure PHY_RESUMING state change is always processed · db9683fb
      Tim Beale authored
      If phy_start_aneg() was called while the phydev is in the PHY_RESUMING
      state, then its state would immediately transition to PHY_AN (or
      PHY_FORCING). This meant the phy_state_machine() never processed the
      PHY_RESUMING state change, which meant interrupts weren't enabled for the
      PHY. If the PHY used low-power mode (i.e. using BMCR_PDOWN), then the
      physical link wouldn't get powered up again.
      
      There seems no point for phy_start_aneg() to make the PHY_RESUMING -->
      PHY_AN transition, as the state machine will do this anyway. I'm not sure
      about the case where autoneg is disabled, as my patch will change
      behaviour so that the PHY goes to PHY_NOLINK instead of PHY_FORCING. An
      alternative solution would be to move the phy_config_interrupt() and
      phy_resume() work out of the state machine and into phy_start().
      
      The background behind this: we're running linux v3.16.7 and from user-space
      we want to enable the eth port (i.e. do a SIOCSIFFLAGS ioctl with the
      IFF_UP flag) and immediately afterward set the interface's speed/duplex.
      Enabling the interface calls .ndo_open() then phy_start() and the PHY
      transitions PHY_HALTED --> PHY_RESUMING. Setting the speed/duplex ends up
      calling phy_ethtool_sset(), which calls phy_start_aneg() (meanwhile the
      phy_state_machine() hasn't processed the PHY_RESUMING state change yet).

      netlink: Reset portid after netlink_insert failure · c0bb07df
      Herbert Xu authored
      The commit c5adde94 ("netlink:
      eliminate nl_sk_hash_lock") breaks the autobind retry mechanism
      because it doesn't reset portid after a failed netlink_insert.
      
      This means that should autobind fail the first time around, then
      the socket will be stuck in limbo as it can never be bound again
      since it already has a non-zero portid.

      net: phy: Allow EEE for all RGMII variants · 7e140696
      Florian Fainelli authored
      RGMII interfaces come in multiple flavors: RGMII with transmit or
      receive internal delay, no delays at all, or delays in both direction.
      
      This change extends the initial check for PHY_INTERFACE_MODE_RGMII to
      cover all of these variants since EEE should be allowed for any of these
      modes, since it is a property of the RGMII, hence Gigabit PHY capability
      more than the RGMII electrical interface and its delays.

      rocker: fix a neigh entry leak issue · 1f9993f6
      Ying Xue authored
      Once we get a neighbour through looking up arp cache or creating a
      new one in rocker_port_ipv4_resolve(), the neighbour's refcount is
      already taken. But as we don't put the refcount again after it's
      used, this makes the neighbour entry leaked.

      and nl_table_lock.
      
      If nl_table is sharing one cache line with one of them, netlink
      performance is really bad on SMP.

      Putting nl_table in read_mostly section increased performance
      of my open/delete netlink sockets test by about 80 %
      
      This came up while diagnosing a getaddrinfo() problem.

      vlan: Correctly propagate promisc|allmulti flags in notifier. · be346ffa
      Vlad Yasevich authored
      Currently vlan notifier handler will try to update all vlans
      for a device when that device comes up.  A problem occurs,
      however, when the vlan device was set to promiscuous, but not
      by the user (ex: a bridge).  In that case, dev->gflags are
      not updated.  What results is that the lower device ends
      up with an extra promiscuity count.  Here are the
      backtraces that prove this:
      [62852.052179]  [<ffffffff814fe248>] __dev_set_promiscuity+0x38/0x1e0
      [62852.052186]  [<ffffffff8160bcbb>] ? _raw_spin_unlock_bh+0x1b/0x40
      [62852.052188]  [<ffffffff814fe4be>] ? dev_set_rx_mode+0x2e/0x40
      [62852.052190]  [<ffffffff814fe694>] dev_set_promiscuity+0x24/0x50
      [62852.052194]  [<ffffffffa0324795>] vlan_dev_open+0xd5/0x1f0 [8021q]
      [62852.052196]  [<ffffffff814fe58f>] __dev_open+0xbf/0x140
      [62852.052198]  [<ffffffff814fe88d>] __dev_change_flags+0x9d/0x170
      [62852.052200]  [<ffffffff814fe989>] dev_change_flags+0x29/0x60
      
      The above comes from the setting the vlan device to IFF_UP state.
      
      [62852.053569]  [<ffffffff814fe248>] __dev_set_promiscuity+0x38/0x1e0
      [62852.053571]  [<ffffffffa032459b>] ? vlan_dev_set_rx_mode+0x2b/0x30
      [8021q]
      [62852.053573]  [<ffffffff814fe8d5>] __dev_change_flags+0xe5/0x170
      [62852.053645]  [<ffffffff814fe989>] dev_change_flags+0x29/0x60
      [62852.053647]  [<ffffffffa032334a>] vlan_device_event+0x18a/0x690
      [8021q]
      [62852.053649]  [<ffffffff8161036c>] notifier_call_chain+0x4c/0x70
      [62852.053651]  [<ffffffff8109d456>] raw_notifier_call_chain+0x16/0x20
      [62852.053653]  [<ffffffff814f744d>] call_netdevice_notifiers+0x2d/0x60
      [62852.053654]  [<ffffffff814fe1a3>] __dev_notify_flags+0x33/0xa0
      [62852.053656]  [<ffffffff814fe9b2>] dev_change_flags+0x52/0x60
      [62852.053657]  [<ffffffff8150cd57>] do_setlink+0x397/0xa40
      
      And this one comes from the notification code.  What we end
      up with is a vlan with promiscuity count of 1 and and a physical
      device with a promiscuity count of 2.  They should both have
      a count 1.
      
      To resolve this issue, vlan code can use dev_get_flags() api
      which correctly masks promiscuity and allmulti flags.

      net: phy: micrel: Fix regression in kszphy_probe · bced8701
      Niklas Cassel authored
      Don't do clock-mode-select if clk == NULL,
      since when building without CONFIG_HAVE_CLK,
      clk_get returns NULL and clk_get_rate returns 0.
      
      Doing clock-mode-select in this cause causes kszphy_probe to
      return -EINVAL and thus prevents the device from being probed.
      
      The original code (before regression) would return 0
      when building without CONFIG_HAVE_CLK.
