      bonding: fix a div error caused by the slave release path · ee6154e1
      Nikolay Aleksandrov authored
      There's a bug in the slave release function which leads the transmit
      functions which use the bond->slave_cnt to a div by 0 because we might
      just have released our last slave and made slave_cnt == 0 but at the same
      time we may have a transmitter after the check for an empty list which will
      fetch it and use it in the slave id calculation.
      Fix it by moving the slave_cnt after synchronize_rcu so if this was our
      last slave any new transmitters will see an empty slave list which is
      checked after rcu lock but before calling the mode transmit functions
      which rely on bond->slave_cnt.
      
      Fixes: 278b2083

      ====================
      Fix RTNL: assertion failed at net/core/rtnetlink.c
      
      The commit 1d3ee88a
      
      
      (bonding: add netlink attributes to slave link dev)
      make the bond_set_active_slave() and bond_set_backup_slave()
      use rtmsg_ifinfo to send slave's states and this functions
      should be called in RTNL.
      
      But the 902.3ad and ARP monitor did not hold the RTNL when calling
      thses two functions, so fix them.
      
      v1->v2: Add new micro to indicate that the notification should be send
              later, not never.
              And add a new patch to fix the same problem for ARP mode.
      
      v2->v3: modify the bond_should_notify to should_notify_rtnl, it is more
      	reasonable, and	use bool for should_notify_rtnl.

      bonding: Fix RTNL: assertion failed at net/core/rtnetlink.c for ab arp monitor · b0929915
      dingtianhong authored
      Veaceslav has reported and fix this problem by commit f2ebd477
      
      
      (bonding: restructure locking of bond_ab_arp_probe()). According Jay's
      opinion, the current solution is not very well, because the notification
      is to indicate that the interface has actually changed state in a meaningful
      way, but these calls in the ab ARP monitor are internal settings of the flags
      to allow the ARP monitor to search for a slave to become active when there are
      no active slaves. The flag setting to active or backup is to permit the ARP
      monitor's response logic to do the right thing when deciding if the test
      slave (current_arp_slave) is up or not.
      
      So the best way to fix the problem is that we should not send a notification
      when the slave is in testing state, and check the state at the end of the
      monitor, if the slave's state recover, avoid to send pointless notification
      twice. And RTNL is really a big lock, hold it regardless the slave's state
      changed or not when the current_active_slave is null will loss performance
      (every 100ms), so we should hold it only when the slave's state changed and
      need to notify.
      
      I revert the old commit and add new modifications.

      bonding: Fix RTNL: assertion failed at net/core/rtnetlink.c for 802.3ad mode · 5e5b0665
      dingtianhong authored
      The problem was introduced by the commit 1d3ee88a
      
      
      (bonding: add netlink attributes to slave link dev).
      The bond_set_active_slave() and bond_set_backup_slave()
      will use rtmsg_ifinfo to send slave's states, so these
      two functions should be called in RTNL.
      
      In 802.3ad mode, acquiring RTNL for the __enable_port and
      __disable_port cases is difficult, as those calls generally
      already hold the state machine lock, and cannot unconditionally
      call rtnl_lock because either they already hold RTNL (for calls
      via bond_3ad_unbind_slave) or due to the potential for deadlock
      with bond_3ad_adapter_speed_changed, bond_3ad_adapter_duplex_changed,
      bond_3ad_link_change, or bond_3ad_update_lacp_rate.  All four of
      those are called with RTNL held, and acquire the state machine lock
      second.  The calling contexts for __enable_port and __disable_port
      already hold the state machine lock, and may or may not need RTNL.
      
      According to the Jay's opinion, I don't think it is a problem that
      the slave don't send notify message synchronously when the status
      changed, normally the state machine is running every 100 ms, send
      the notify message at the end of the state machine if the slave's
      state changed should be better.
      
      I fix the problem through these steps:
      
      1). add a new function bond_set_slave_state() which could change
          the slave's state and call rtmsg_ifinfo() according to the input
          parameters called notify.
      
      2). Add a new slave parameter which called should_notify, if the slave's state
          changed and don't notify yet, the parameter will be set to 1, and then if
          the slave's state changed again, the param will be set to 0, it indicate that
          the slave's state has been restored, no need to notify any one.
      
      3). the __enable_port and __disable_port should not call rtmsg_ifinfo
          in the state machine lock, any change in the state of slave could
          set a flag in the slave, it will indicated that an rtmsg_ifinfo
          should be called at the end of the state machine.

      net: tcp: use NET_INC_STATS() · 9a9bfd03
      Eric Dumazet authored
      
      
      While LINUX_MIB_TCPSPURIOUS_RTX_HOSTQUEUES can only be incremented
      in tcp_transmit_skb() from softirq (incoming message or timer
      activation), it is better to use NET_INC_STATS() instead of
      NET_INC_STATS_BH() as tcp_transmit_skb() can be called from process
      context.
      
      This will avoid copy/paste confusion when/if we want to add
      other SNMP counters in tcp_transmit_skb()

      xfrm: Fix unlink race when policies are deleted. · 3a9016f9
      Steffen Klassert authored
      
      
      When a policy is unlinked from the lists in thread context,
      the xfrm timer can fire before we can mark this policy as dead.
      So reinitialize the bydst hlist, then hlist_unhashed() will
      notice that this policy is not linked and will avoid a
      doulble unlink of that policy.
