      rtnl: limit IFLA_NUM_TX_QUEUES and IFLA_NUM_RX_QUEUES to 4096 · 0e1d6eca
      Eric Dumazet authored
      We have an impressive number of syzkaller bugs that are linked
      to the fact that syzbot was able to create a networking device
      with millions of TX (or RX) queues.
      
      Let's limit the number of RX/TX queues to 4096, this really should
      cover all known cases.
      
      A separate patch will add various cond_resched() in the loops
      handling sysfs entries at device creation and dismantle.
      
      Tested:
      
      lpaa6:~# ip link add gre-4097 numtxqueues 4097 numrxqueues 4097 type ip6gretap
      RTNETLINK answers: Invalid argument

      bonding: fix warning message · 0f3b914c
      Mahesh Bandewar authored
      RX queue config for bonding master could be different from its slave
      device(s). With the commit 6a9e461f ("bonding: pass link-local
      packets to bonding master also."), the packet is reinjected into stack
      with skb->dev as bonding master. This potentially triggers the
      message:
      
         "bondX received packet on queue Y, but number of RX queues is Z"
      
      whenever the queue that packet is received on is higher than the
      numrxqueues on bonding master (Y > Z).
      
      Fixes: 6a9e461f ("bonding: pass link-local packets to bonding master also.")

      inet: make sure to grab rcu_read_lock before using ireq->ireq_opt · 2ab2ddd3
      Eric Dumazet authored
      Timer handlers do not imply rcu_read_lock(), so my recent fix
      triggered a LOCKDEP warning when SYNACK is retransmit.
      
      Lets add rcu_read_lock()/rcu_read_unlock() pairs around ireq->ireq_opt
      usages instead of guessing what is done by callers, since it is
      not worth the pain.
      
      Get rid of ireq_opt_deref() helper since it hides the logic
      without real benefit, since it is now a standard rcu_dereference().

      nfp: avoid soft lockups under control message storm · ff58e2df
      Jakub Kicinski authored
      When FW floods the driver with control messages try to exit the cmsg
      processing loop every now and then to avoid soft lockups.  Cmsg
      processing is generally very lightweight so 512 seems like a reasonable

      declance: Fix continuation with the adapter identification message · fe3a83af
      Maciej W. Rozycki authored
      Fix a commit 4bcc595c ("printk: reinstate KERN_CONT for printing
      continuation lines") regression with the `declance' driver, which caused
      the adapter identification message to be split between two lines, e.g.:
      
      declance.c: v0.011 by Linux MIPS DECstation task force
      tc6: PMAD-AA
      , addr = 08:00:2b:1b:2a:6a, irq = 14
      tc6: registered as eth0.
      
      Address that properly, by printing identification with a single call,
      making the messages now look like:
      
      declance.c: v0.011 by Linux MIPS DECstation task force
      tc6: PMAD-AA, addr = 08:00:2b:1b:2a:6a, irq = 14

      net: fec: fix rare tx timeout · 657ade07
      Rickard x Andersson authored
      During certain heavy network loads TX could time out
      with TX ring dump.
      TX is sometimes never restarted after reaching
      "tx_stop_threshold" because function "fec_enet_tx_queue"
      only tests the first queue.
      
      In addition the TX timeout callback function failed to
      recover because it also operated only on the first queue.

      r8169: fix network stalls due to missing bit TXCFG_AUTO_FIFO · ad5f97fa
      Heiner Kallweit authored
      Some of the chip-specific hw_start functions set bit TXCFG_AUTO_FIFO
      in register TxConfig. The original patch changed the order of some
      calls resulting in these changes being overwritten by
      rtl_set_tx_config_registers() in rtl_hw_start(). This eventually
      resulted in network stalls especially under high load.
      
      Analyzing the chip-specific hw_start functions all chip version from
      34, with the exception of version 39, need this bit set.
      This patch moves setting this bit to rtl_set_tx_config_registers().

      tun: napi flags belong to tfile · af3fb24e
      Eric Dumazet authored
      Since tun->flags might be shared by multiple tfile structures,
      it is better to make sure tun_get_user() is using the flags
      for the current tfile.
      
      Presence of the READ_ONCE() in tun_napi_frags_enabled() gave a hint
      of what could happen, but we need something stronger to please
      syzbot.

      bond: take rcu lock in netpoll_send_skb_on_dev · 6fe94878
      Dave Jones authored
      The bonding driver lacks the rcu lock when it calls down into
      netdev_lower_get_next_private_rcu from bond_poll_controller, which
      results in a trace like:

      rtnetlink: Fail dump if target netnsid is invalid · 893626d6
      David Ahern authored
      Link dumps can return results from a target namespace. If the namespace id
      is invalid, then the dump request should fail if get_target_net fails
      rather than continuing with a dump of the current namespace.

      Flavio Leitner authored
      This reverts commit 90c7afc9.
      
      When the commit was merged, the code used nf_ct_put() to free
      the entry, but later on commit 76644232 ("openvswitch: Free
      tmpl with tmpl_free.") replaced that with nf_ct_tmpl_free which
      is a more appropriate. Now the original problem is removed.
      
      Then 44d6e2f2 ("net: Replace NF_CT_ASSERT() with WARN_ON().")
      replaced a debug assert with a WARN_ON() which is trigged now.

      tipc: ignore STATE_MSG on wrong link session · d949cfed
      LUU Duc Canh authored
      The initial session number when a link is created is based on a random
      value, taken from struct tipc_net->random. It is then incremented for
      each link reset to avoid mixing protocol messages from different link
      sessions.
      
      However, when a bearer is reset all its links are deleted, and will
      later be re-created using the same random value as the first time.
      This means that if the link never went down between creation and
      deletion we will still sometimes have two subsequent sessions with
      the same session number. In virtual environments with potentially
      long transmission times this has turned out to be a real problem.
      
      We now fix this by randomizing the session number each time a link
      is created.
      
      With a session number size of 16 bits this gives a risk of session
      collision of 1/64k. To reduce this further, we also introduce a sanity
      check on the very first STATE message arriving at a link. If this has
      an acknowledge value differing from 0, which is logically impossible,
      we ignore the message. The final risk for session collision is hence
      reduced to 1/4G, which should be sufficient.

      If "td->u.target_size" is larger than sizeof(struct xt_entry_target) we
      return -EINVAL.  But we don't check whether it's smaller than
      sizeof(struct xt_entry_target) and that could lead to an out of bounds
      read.

      ====================
      pull request (net): ipsec 2018-10-01
      
      1) Validate address prefix lengths in the xfrm selector,
         otherwise we may hit undefined behaviour in the
         address matching functions if the prefix is too
         big for the given address family.
      
      2) Fix skb leak on local message size errors.
         From Thadeu Lima de Souza Cascardo.
      
      3) We currently reset the transport header back to the network
         header after a transport mode transformation is applied. This
         leads to an incorrect transport header when multiple transport
         mode transformations are applied. Reset the transport header
         only after all transformations are already applied to fix this.
         From Sowmini Varadhan.
      
      4) We only support one offloaded xfrm, so reset crypto_done after
         the first transformation in xfrm_input(). Otherwise we may call
         the wrong input method for subsequent transformations.
         From Sowmini Varadhan.
      
      5) Fix NULL pointer dereference when skb_dst_force clears the dst_entry.
         skb_dst_force does not really force a dst refcount anymore, it might
         clear it instead. xfrm code did not expect this, add a check to not
         dereference skb_dst() if it was cleared by skb_dst_force.
      
      6) Validate xfrm template mode, otherwise we can get a stack-out-of-bounds
         read in xfrm_state_find. From Sean Tranchetti.
      
      Please pull or let me know if there are problems.
