      IPVS: Use global mutex in ip_vs_app.c · 736561a0
      Simon Horman authored
      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 authored
      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 authored
      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.
      
      This was initially reported at https://bugzilla.kernel.org/show_bug.cgi?id=31232

      macvlan: Fix use after free of struct macvlan_port. · d5cd9244
      Eric W. Biederman authored
      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 authored
      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.
      
      The patch below fixes things for me.

      net/appletalk: fix atalk_release use after free · b20e7bbf
      Arnd Bergmann authored
      The BKL removal in appletalk introduced a use-after-free problem,
      where atalk_destroy_socket frees a sock, but we still release
      the socket lock on it.
      
      An easy fix is to take an extra reference on the sock and sock_put
      it when returning from atalk_release.

      Commit b0d0d915 (remove the BKL) added a regression, because
      sock_put() can free memory while we are going to use it later.
      
      Fix is to delay sock_put() _after_ release_sock().

      xfrm: Fix initialize repl field of struct xfrm_state · a454f0cc
      Wei Yongjun authored
      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()

      Reduce sequential pointer derefs in scsi_error.c and reduce size as well · 0bf8c869

      This patch reduces the number of sequential pointer derefs in
      drivers/scsi/scsi_error.c
      
      This has been submitted a number of times over a couple of years.  I
      believe this version adresses all comments it has gathered over time.
      Please apply or reject with a reason.
      
      The benefits are:
      
       - makes the code easier to read.  Lots of sequential derefs of the same
         pointers is not easy on the eye.
      
       - theoretically at least, just dereferencing the pointers once can
         allow the compiler to generally slightly faster code, so in theory
         this could also be a micro speed optimization.
      
       - reduces size of object file (tiny effect: on x86-64, in at least one
         configuration, the text size decreased from 9439 bytes to 9400)
      
       - removes some pointless (mostly trailing) whitespace.

      banner, login prompt, etc) on the console when X is not running and
      total lack of text on all of the virtual consoles after X is started.
      
      Any concerns that the incorrect code (upstream since October 2008) has
      been successfully used on non-IBM G200eV equipped system(s) appear to be
      unwarranted.  In addition to the serious/non-intermittent nature of
      issues that have been spotted on IBM systems, complete removal of the
      incorrect code is clearly supported by the following Matrox (Yannick
      Heneault) provided input:
       "It impossible that this patch should have work on a system.
       The patch only declare the G200eV as a regular G200 which is
       not case. Many registers are different, including at least the
       PLL programming sequence. If the G200eV is programmed like a
       regular G200, it will not display anything."
      
      v1 - Initial patch that removed the incorrect code for _all_
           G200eV equipped systems.
      v2 - Darrick Wong provided patch that blacklisted the incorrect
           code on G200eV equipped IBM systems leaving it enabled on
           all G200eV equipped non-IBM systems.
      v3 - Same code changes included with v1 plus additional
           justification for complete removal of the incorrect code.

      Prevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal code · da48524e
      Julien Tinnes authored
      Userland should be able to trust the pid and uid of the sender of a
      signal if the si_code is SI_TKILL.
      
      Unfortunately, the kernel has historically allowed sigqueueinfo() to
      send any si_code at all (as long as it was negative - to distinguish it
      from kernel-generated signals like SIGILL etc), so it could spoof a
      SI_TKILL with incorrect siginfo values.
      
      Happily, it looks like glibc has always set si_code to the appropriate
      SI_QUEUE, so there are probably no actual user code that ever uses
      anything but the appropriate SI_QUEUE flag.
      
      So just tighten the check for si_code (we used to allow any negative
      value), and add a (one-time) warning in case there are binaries out
      there that might depend on using other si_code values.

      SMSC SCH5627 Super I/O chips include complete hardware monitoring
      capabilities. They can monitor up to 5 voltages, 4 fans and 8
      temperatures.
      
      The hardware monitoring part of the SMSC SCH5627 is accessed by talking
      through an embedded microcontroller. An application note describing the
      protocol for communicating with the microcontroller is available upon
      request. Please mail me if you want a copy.

      hwmon: (lm75) Speed up detection · e76f67b5
      Jean Delvare authored
      Make the LM75/LM75A device detection faster:
      
      * Don't read the current temperature value when we don't use it.
      * Check for unused bits in the configuration register as soon as we
        have read its value.
      * Don't use word reads, not all devices support this, and some which
        don't misbehave when you try.
      * Check for cycling register values every 40 register addresses
        instead of every 8, it's 5 times faster and just as efficient.
      
      Some of these improvements come straight from the user-space
      sensors-detect script, so both detection routines are in line now.
