      netrom: hold sock when setting skb->destructor · 4638faac
      Cong Wang authored
      sock_efree() releases the sock refcnt, if we don't hold this refcnt
      when setting skb->destructor to it, the refcnt would not be balanced.
      This leads to several bug reports from syzbot.
      
      I have checked other users of sock_efree(), all of them hold the
      sock refcnt.

      ovs: datapath: hide clang frame-overflow warnings · 26063790
      Arnd Bergmann authored
      Some functions in the datapath code are factored out so that each
      one has a stack frame smaller than 1024 bytes with gcc. However,
      when compiling with clang, the functions are inlined more aggressively
      and combined again so we get
      
      net/openvswitch/datapath.c:1124:12: error: stack frame size of 1528 bytes in function 'ovs_flow_cmd_set' [-Werror,-Wframe-larger-than=]
      
      Marking both get_flow_actions() and ovs_nla_init_match_and_action()
      as 'noinline_for_stack' gives us the same behavior that we see with
      gcc, and no warning. Note that this does not mean we actually use
      less stack, as the functions call each other, and we still get
      three copies of the large 'struct sw_flow_key' type on the stack.
      
      The comment tells us that this was previously considered safe,
      presumably since the netlink parsing functions are called with
      a known backchain that does not also use a lot of stack space.
      
      Fixes: 9cc9a5cb ("datapath: Avoid using stack larger than 1024.")

      net: phylink: don't start and stop SGMII PHYs in SFP modules twice · c7fa7f56
      Arseny Solokha authored
      SFP modules connected using the SGMII interface have their own PHYs which
      are handled by the struct phylink's phydev field. On the other hand, for
      the modules connected using 1000Base-X interface that field is not set.
      
      Since commit ce0aa27f ("sfp: add sfp-bus to bridge between network
      devices and sfp cages") phylink_start() ends up setting the phydev field
      using the sfp-bus infrastructure, which eventually calls phy_start() on it,
      and then calling phy_start() again on the same phydev from phylink_start()
      itself. Similar call sequence holds for phylink_stop(), only in the reverse
      order. This results in WARNs during network interface bringup and shutdown
      when a copper SFP module is connected, as phy_start() and phy_stop() are
      called twice in a row for the same phy_device:

      can: rcar_canfd: fix possible IRQ storm on high load · d4b890ae
      Nikita Yushchenko authored
      We have observed rcar_canfd driver entering IRQ storm under high load,
      with following scenario:
      - rcar_canfd_global_interrupt() in entered due to Rx available,
      - napi_schedule_prep() is called, and sets NAPIF_STATE_SCHED in state
      - Rx fifo interrupts are masked,
      - rcar_canfd_global_interrupt() is entered again, this time due to
        error interrupt (e.g. due to overflow),
      - since scheduled napi poller has not yet executed, condition for calling
        napi_schedule_prep() from rcar_canfd_global_interrupt() remains true,
        thus napi_schedule_prep() gets called and sets NAPIF_STATE_MISSED flag
        in state,
      - later, napi poller function rcar_canfd_rx_poll() gets executed, and
        calls napi_complete_done(),
      - due to NAPIF_STATE_MISSED flag in state, this call does not clear
        NAPIF_STATE_SCHED flag from state,
      - on return from napi_complete_done(), rcar_canfd_rx_poll() unmasks Rx
        interrutps,
      - Rx interrupt happens, rcar_canfd_global_interrupt() gets called
        and calls napi_schedule_prep(),
      - since NAPIF_STATE_SCHED is set in state at this time, this call
        returns false,
      - due to that false return, rcar_canfd_global_interrupt() returns
        without masking Rx interrupt
      - and this results into IRQ storm: unmasked Rx interrupt happens again
        and again is misprocessed in the same way.
      
      This patch fixes that scenario by unmasking Rx interrupts only when
      napi_complete_done() returns true, which means it has cleared
      NAPIF_STATE_SCHED in state.

      can: dev: call netif_carrier_off() in register_candev() · c6384560
      Rasmus Villemoes authored
      CONFIG_CAN_LEDS is deprecated. When trying to use the generic netdev
      trigger as suggested, there's a small inconsistency with the link
      property: The LED is on initially, stays on when the device is brought
      up, and then turns off (as expected) when the device is brought down.
      
      Make sure the LED always reflects the state of the CAN device.

      bonding: Force slave speed check after link state recovery for 802.3ad · 12185dfe
      Thomas Falcon authored
      The following scenario was encountered during testing of logical
      partition mobility on pseries partitions with bonded ibmvnic
      adapters in LACP mode.
      
      1. Driver receives a signal that the device has been
         swapped, and it needs to reset to initialize the new
         device.
      
      2. Driver reports loss of carrier and begins initialization.
      
      3. Bonding driver receives NETDEV_CHANGE notifier and checks
         the slave's current speed and duplex settings. Because these
         are unknown at the time, the bond sets its link state to
         BOND_LINK_FAIL and handles the speed update, clearing
         AD_PORT_LACP_ENABLE.
      
      4. Driver finishes recovery and reports that the carrier is on.
      
      5. Bond receives a new notification and checks the speed again.
         The speeds are valid but miimon has not altered the link
         state yet.  AD_PORT_LACP_ENABLE remains off.
      
      Because the slave's link state is still BOND_LINK_FAIL,
      no further port checks are made when it recovers. Though
      the slave devices are operational and have valid speed
      and duplex settings, the bond will not send LACPDU's. The
      simplest fix I can see is to force another speed check
      in bond_miimon_commit. This way the bond will update
      AD_PORT_LACP_ENABLE if needed when transitioning from
      BOND_LINK_FAIL to BOND_LINK_UP.

      Pull preemption Kconfig fix from Thomas Gleixner:
       "The PREEMPT_RT stub config renamed PREEMPT to PREEMPT_LL and defined
        PREEMPT outside of the menu and made it selectable by both PREEMPT_LL
        and PREEMPT_RT.
      
        Stupid me missed that 114 defconfigs select CONFIG_PREEMPT which
        obviously can't work anymore. oldconfig builds are affected as well,
        but it's more obvious as the user gets asked. [old]defconfig silently
        fixes it up and selects PREEMPT_NONE.
      
        Unbreak it by undoing the rename and adding a intermediate config
        symbol which is selected by both PREEMPT and PREEMPT_RT. That requires
        to chase down a few #ifdefs, but it's better than tweaking 114
        defconfigs and annoying users"

      sched/rt, Kconfig: Unbreak def/oldconfig with CONFIG_PREEMPT=y · b8d33498
      Thomas Gleixner authored
      The merge of the CONFIG_PREEMPT_RT stub renamed CONFIG_PREEMPT to
      CONFIG_PREEMPT_LL which causes all defconfigs which have CONFIG_PREEMPT=y
      set to fall back to CONFIG_PREEMPT_NONE because CONFIG_PREEMPT depends on
      the preemption mode choice wich defaults to NONE. This also affects
      oldconfig builds.
      
      So rather than changing 114 defconfig files and being an annoyance to
      users, revert the rename and select a new config symbol PREEMPTION. That
      keeps everything working smoothly and the revelant ifdef's are going to be
      fixed up step by step.
