      ipv4: optimize route adding on secondary promotion · 04024b93
      Julian Anastasov 提交于
      Optimize the calling of fib_add_ifaddr for all
      secondary addresses after the promoted one to start from
      their place, not from the new place of the promoted
      secondary. It will save some CPU cycles because we
      are sure the promoted secondary was first for the subnet
      and all next secondaries do not change their place.

      ipv4: remove the routes on secondary promotion · 2d230e2b
      Julian Anastasov 提交于
      The secondary address promotion relies on fib_sync_down_addr
      to remove all routes created for the secondary addresses when
      the old primary address is deleted. It does not happen for cases
      when the primary address is also in another subnet. Fix that
      by deleting local and broadcast routes for all secondaries while
      they are on device list and by faking that all addresses from
      this subnet are to be deleted. It relies on fib_del_ifaddr being
      able to ignore the IPs from the concerned subnet while checking
      for duplication.

      ipv4: fix route deletion for IPs on many subnets · e6abbaa2
      Julian Anastasov 提交于
      Alex Sidorenko reported for problems with local
      routes left after IP addresses are deleted. It happens
      when same IPs are used in more than one subnet for the
      device.
      
      	Fix fib_del_ifaddr to restrict the checks for duplicate
      local and broadcast addresses only to the IFAs that use
      our primary IFA or another primary IFA with same address.
      And we expect the prefsrc to be matched when the routes
      are deleted because it is possible they to differ only by
      prefsrc. This patch prevents local and broadcast routes
      to be leaked until their primary IP is deleted finally
      from the box.
      
      	As the secondary address promotion needs to delete
      the routes for all secondaries that used the old primary IFA,
      add option to ignore these secondaries from the checks and
      to assume they are already deleted, so that we can safely
      delete the route while these IFAs are still on the device list.

      ipv4: match prefsrc when deleting routes · 74cb3c10
      Julian Anastasov 提交于
      fib_table_delete forgets to match the routes by prefsrc.
      Callers can specify known IP in fc_prefsrc and we should remove
      the exact route. This is needed for cases when same local or
      broadcast addresses are used in different subnets and the
      routes differ only in prefsrc. All callers that do not provide
      fc_prefsrc will ignore the route prefsrc as before and will
      delete the first occurence. That is how the ip route del default
      magic works.
      
      	Current callers are:
      
      - ip_rt_ioctl where rtentry_to_fib_config provides fc_prefsrc only
      when the provided device name matches IP label with colon.
      
      - inet_rtm_delroute where RTA_PREFSRC is optional too
      
      - fib_magic which deals with routes when deleting addresses
      and where the fc_prefsrc is always set with the primary IP
      for the concerned IFA.

      IPVS: Use global mutex in ip_vs_app.c · 736561a0
      Simon Horman 提交于
      As part of the work to make IPVS network namespace aware
      __ip_vs_app_mutex was replaced by a per-namespace lock,
      ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes.
      
      Unfortunately this implementation results in ipvs->app_key residing
      in non-static storage which at the very least causes a lockdep warning.
      
      This patch takes the rather heavy-handed approach of reinstating
      __ip_vs_app_mutex which will cover access to the ipvs->list_head
      of all network namespaces.

      veth: Fix the byte counters · 675071a2
      Eric W. Biederman 提交于
      Commit 44540960 "veth: move loopback logic to common location" introduced
      a bug in the packet counters.  I don't understand why that happened as it
      is not explained in the comments and the mut check in dev_forward_skb
      retains the assumption that skb->len is the total length of the packet.
      
      I just measured this emperically by setting up a veth pair between two
      noop network namespaces setting and attempting a telnet connection between
      the two.  I saw three packets in each direction and the byte counters were
      exactly 14*3 = 42 bytes high in each direction.  I got the actual
      packet lengths with tcpdump.
      
      So remove the extra ETH_HLEN from the veth byte count totals.

      net ipv6: Fix duplicate /proc/sys/net/ipv6/neigh directory entries. · 9d2a8fa9
      Eric W. Biederman 提交于
      When I was fixing issues with unregisgtering tables under /proc/sys/net/ipv6/neigh
      by adding a mount point it appears I missed a critical ordering issue, in the
      ipv6 initialization.  I had not realized that ipv6_sysctl_register is called
      at the very end of the ipv6 initialization and in particular after we call
      neigh_sysctl_register from ndisc_init.
      
      "neigh" needs to be initialized in ipv6_static_sysctl_register which is
      the first ipv6 table to initialized, and definitely before ndisc_init.
      This removes the weirdness of duplicate tables while still providing a
      "neigh" mount point which prevents races in sysctl unregistering.

      macvlan: Fix use after free of struct macvlan_port. · d5cd9244
      Eric W. Biederman 提交于
      When the macvlan driver was extended to call unregisgter_netdevice_queue
      in 23289a37, a use after free of struct
      macvlan_port was introduced.  The code in dellink relied on unregister_netdevice
      actually unregistering the net device so it would be safe to free macvlan_port.
      
      Since unregister_netdevice_queue can just queue up the unregister instead of
      performing the unregiser immediately we free the macvlan_port too soon and
      then the code in macvlan_stop removes the macaddress for the set of macaddress
      to listen for and uses memory that has already been freed.
      
      To fix this add a reference count to track when it is safe to free the macvlan_port
      and move the call of macvlan_port_destroy into macvlan_uninit which is guaranteed
      to be called after the final macvlan_port_close.

      can: c_can: Do basic c_can configuration _before_ enabling the interrupts · 4f2d56c4
      Jan Altenberg 提交于
      I ran into some trouble while testing the SocketCAN driver for the BOSCH
      C_CAN controller. The interface is not correctly initialized, if I put
      some CAN traffic on the line, _while_ the interface is being started
      (which means: the interface doesn't come up correcty, if there's some RX
      traffic while doing 'ifconfig can0 up').
      
      The current implementation enables the controller interrupts _before_
      doing the basic c_can configuration. I think, this should be done the
      other way round.

      We dont need to test if we run from softirq context, we definitely are.
      
      This saves few instructions in ip_rcv() & ip_rcv_finish()

      xfrm: Fix initialize repl field of struct xfrm_state · a454f0cc
      Wei Yongjun 提交于
      Commit 'xfrm: Move IPsec replay detection functions to a separate file'
        (9fdc4883)
      introduce repl field to struct xfrm_state, and only initialize it
      under SA's netlink create path, the other path, such as pf_key,
      ipcomp/ipcomp6 etc, the repl field remaining uninitialize. So if
      the SA is created by pf_key, any input packet with SA's encryption
      algorithm will cause panic.
      
          int xfrm_input()
          {
              ...
              x->repl->advance(x, seq);
              ...
          }
      
      This patch fixed it by introduce new function __xfrm_init_state().

      mac80211: initialize sta->last_rx in sta_info_alloc · 8bc8aecd
      Felix Fietkau 提交于
      This field is used to determine the inactivity time. When in AP mode,
      hostapd uses it for kicking out inactive clients after a while. Without this
      patch, hostapd immediately deauthenticates a new client if it checks the
      inactivity time before the client sends its first data frame.

      ath9k: Fix kernel panic in AR2427 · 61e1b0b0
      Mohammed Shafi Shajakhan 提交于
      Kernel panic occurs just after AR2427 establishes connection with AP.
      Unless aggregation is enabled we don't initialize the TID structure.
      Thus accesing the elements of the TID structure when aggregation is
      disabled, leads to NULL pointer dereferencing.
