      irda: stop calling sk_prot->disconnect() on connection failure · 4cb8c359
      Linus Torvalds authored
      The sk_prot is irda's own set of protocol handlers, so irda should
      statically know what that function is anyway, without using an indirect
      pointer.  And as it happens, we know *exactly* what that pointer is
      statically: it's NULL, because irda doesn't define a disconnect
      So calling that function is doubly wrong, and will just cause an oops.

      KVM: nVMX: Disable preemption while reading from shadow VMCS · 282da870
      Jan Kiszka authored
      In order to access the shadow VMCS, we need to load it. At this point,
      vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
      we now get preempted by Linux, vmx_vcpu_put and, on return, the
      vmx_vcpu_load will work against the wrong vmcs. That can cause
      copy_shadow_to_vmcs12 to corrupt the vmcs12 state.
      Fix the issue by disabling preemption during the copy operation.
      copy_vmcs12_to_shadow is safe from this issue as it is executed by
      vmx_vcpu_run when preemption is already disabled before vmentry.
      This bug is exposed by running Jailhouse within KVM on CPUs with
      shadow VMCS support.  Jailhouse never expects an interrupt pending
      vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
      is preempted, the active VMCS happens to have the virtual interrupt
      pending flag set in the CPU-based execution controls.

      KVM: x86: Fix far-jump to non-canonical check · 7e46dddd
      Nadav Amit authored
      Commit d1442d85 ("KVM: x86: Handle errors when RIP is set during far
      jumps") introduced a bug that caused the fix to be incomplete.  Due to
      incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit
      segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may
      not trigger #GP.  As we know, this imposes a security problem.
      In addition, the condition for two warnings was incorrect.

      Pull ACPI and power management fixes from Rafael Wysocki:
       "These are fixes received after my previous pull request plus one that
        has been in the works for quite a while, but its previous version
        caused problems to happen, so it's been deferred till now.
        Fixed are two recent regressions (MFD enumeration and cpufreq-dt),
        ACPI EC regression introduced in 3.17, system suspend error code path
        regression introduced in 3.15, an older bug related to recovery from
        failing resume from hibernation and a cpufreq-dt driver issue related
        to operation performance points.
         - Fix a crash on r8a7791/koelsch during resume from system suspend
           caused by a recent cpufreq-dt commit (Geert Uytterhoeven).
         - Fix an MFD enumeration problem introduced by a recent commit adding
           ACPI support to the MFD subsystem that exposed a weakness in the
           ACPI core causing ACPI enumeration to be applied to all devices
           associated with one ACPI companion object, although it should be
           used for one of them only (Mika Westerberg).
         - Fix an ACPI EC regression introduced during the 3.17 cycle causing
           some Samsung laptops to misbehave as a result of a workaround
           targeted at some Acer machines.  That includes a revert of a commit
           that went too far and a quirk for the Acer machines in question.
           From Lv Zheng.
         - Fix a regression in the system suspend error code path introduced
           during the 3.15 cycle that causes it to fail to take errors from
           asychronous execution of "late" suspend callbacks into account
           (Imre Deak).
         - Fix a long-standing bug in the hibernation resume error code path
           that fails to roll back everything correcty on "freeze" callback
           errors and leaves some devices in a "suspended" state causing more
           breakage to happen subsequently (Imre Deak).
         - Make the cpufreq-dt driver disable operation performance points
           that are not supported by the VR connected to the CPU voltage plane
           with acceptable tolerance instead of constantly failing voltage
           scaling later on (Lucas Stach)"

      x86_64, entry: Fix out of bounds read on sysenter · 653bc77a
      Andy Lutomirski authored
      Rusty noticed a Really Bad Bug (tm) in my NT fix.  The entry code
      reads out of bounds, causing the NT fix to be unreliable.  But, and
      this is much, much worse, if your stack is somehow just below the
      top of the direct map (or a hole), you read out of bounds and crash.
      Excerpt from the crash:
      [    1.129513] RSP: 0018:ffff88001da4bf88  EFLAGS: 00010296
        2b:*    f7 84 24 90 00 00 00     testl  $0x4000,0x90(%rsp)
      That read is deterministically above the top of the stack.  I
      thought I even single-stepped through this code when I wrote it to
      check the offset, but I clearly screwed it up.
      Fixes: 8c7aa698

      drivers: net: cpsw: Support ALLMULTI and fix IFF_PROMISC in switch mode · 1e5c4bc4
      Lennart Sorensen authored
      The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic
      multicast routing not work.  Related to this, when enabling IFF_PROMISC
      in switch mode, all registered multicast addresses are flushed, resulting
      in only broadcast and unicast traffic being received.
      A new cpsw_ale_set_allmulti function now scans through the ALE entry
      table and adds/removes the host port from the unregistered multicast
      port mask of each vlan entry depending on the state of IFF_ALLMULTI.
      In promiscious mode, cpsw_ale_set_allmulti is used to force reception
      of all multicast traffic in addition to the unicast and broadcast traffic.
      With this change dynamic multicast and promiscious mode both work in
      switch mode.

      drivers: net: cpsw: Fix broken loop condition in switch mode · 6f979eb3
      Lennart Sorensen authored
       (drivers: net: cpsw: fix buggy
      loop condition) accidentally fixed a loop comparison in too many places
      while fixing a real bug.
      It was correct to fix the dual_emac mode section since there 'i' is used
      as an index into priv->slaves which is a 0 based array.
      However the other two changes (which are only used in switch mode)
      are wrong since there 'i' is actually the ALE port number, and port 0
      is the host port, while port 1 and up are the slave ports.
      Putting the loop condition back in the switch mode section fixes it.
      A comment has been added to point out the intent clearly to avoid future
      confusion.  Also a comment is fixed that said the opposite of what was
      actually happening.

      If a driver supports reading EEPROM but no EEPROM is installed in the system,
      the driver's get_eeprom_len function returns 0. ethtool will subsequently
      try to read that zero-length EEPROM anyway. If the driver does not support
      EEPROM access at all, this operation will return -EOPNOTSUPP. If the driver
      does support EEPROM access but no EEPROM is installed, the operation will
      return -EINVAL. Return -EOPNOTSUPP in both cases for consistency.

      handled by directly reading the disk in block/partitions/sun.c (enabled by
      CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is
      unused in the driver, remove the call and the field.

        documentation improvements, and, most importantly, fixes for a couple
        of build problems in various bits of sample code.
        I fully intend to start sending pull requests with signed tags.
        However, due to poor planning on my part and the general obnoxiousness
        of life, I'm 2000 miles away from my private key which is sitting on a
        powered-down machine.  This should be fixed before my next request.
        Meanwhile git.lwn.net is a machine under my control, the patches are
        all trivial, and all have done time in linux-next"

      r8152: stop submitting intr for -EPROTO · d59c876d
      hayeswang authored
      For Renesas USB 3.0 host controller, when unplugging the usb hub which
      has the RTL8153 plugged, the driver would get -EPROTO for interrupt
      transfer. There is high probability to get the information of "HC died;
      cleaning up", if the driver continues to submit the interrupt transfer
      before the disconnect() is called.

      This reverts commit 68da1664
      It turns out that the assertion about scope of regressions due to
      always keeping keyboard controller in legacy mode was proven wrong.
      There are laptops, such as Clevo W650SH, that only have internal
      touchpad (no external PS/2 ports), that require active multiplexing
      mode to switch the touchpad (Elantech) into native mode instead of
      basic PS/2 emulation.
