      ipv6: Error when route does not have any valid nexthops · 9eee3b49
      Ido Schimmel authored
      When user space sends invalid information in RTA_MULTIPATH, the nexthop
      list in ip6_route_multipath_add() is empty and 'rt_notif' is set to
      NULL.
      
      The code that emits the in-kernel notifications does not check for this
      condition, which results in a NULL pointer dereference [1].
      
      Fix this by bailing earlier in the function if the parsed nexthop list
      is empty. This is consistent with the corresponding IPv4 code.
      
      v2:
      * Check if parsed nexthop list is empty and bail with extack set

      When calling debugfs functions, there is no need to ever check the
      return value.  The function can work or not, but the code logic should

      net: fastopen: robustness and endianness fixes for SipHash · 438ac880
      Ard Biesheuvel authored
      Some changes to the TCP fastopen code to make it more robust
      against future changes in the choice of key/cookie size, etc.
      
      - Instead of keeping the SipHash key in an untyped u8[] buffer
        and casting it to the right type upon use, use the correct
        type directly. This ensures that the key will appear at the
        correct alignment if we ever change the way these data
        structures are allocated. (Currently, they are only allocated
        via kmalloc so they always appear at the correct alignment)
      
      - Use DIV_ROUND_UP when sizing the u64[] array to hold the
        cookie, so it is always of sufficient size, even if
        TCP_FASTOPEN_COOKIE_MAX is no longer a multiple of 8.
      
      - Drop the 'len' parameter from the tcp_fastopen_reset_cipher()
        function, which is no longer used.
      
      - Add endian swabbing when setting the keys and calculating the hash,
        to ensure that cookie values are the same for a given key and
        source/destination address pair regardless of the endianness of
        the server.
      
      Note that none of these are functional changes wrt the current
      state of the code, with the exception of the swabbing, which only
      affects big endian systems.

      ====================
      PCI: let pci_disable_link_state propagate errors
      
      Drivers like r8169 rely on pci_disable_link_state() having disabled
      certain ASPM link states. If OS can't control ASPM then
      pci_disable_link_state() turns into a no-op w/o informing the caller.
      The driver therefore may falsely assume the respective ASPM link
      states are disabled. Let pci_disable_link_state() propagate errors
      to the caller, enabling the caller to react accordingly.
      
      I'd propose to let this series go through the netdev tree if the PCI
      core extension is acked by the PCI people.

      Certain chip version / board combinations have massive problems if
      ASPM is active. If BIOS enables ASPM and doesn't let OS control it,
      then we may have a problem with the current code. Therefore check the
      return code of pci_disable_link_state() and don't enable ASPM in the
      network chip if OS can't control ASPM.

      Eric Dumazet authored
      tcp_fragment() might be called for skbs in the write queue.
      
      Memory limits might have been exceeded because tcp_sendmsg() only
      checks limits at full skb (64KB) boundaries.
      
      Therefore, we need to make sure tcp_fragment() wont punish applications
      that might have setup very low SO_SNDBUF values.

      x86/vdso: Prevent segfaults due to hoisted vclock reads · ff17bbe0
      Andy Lutomirski authored
      GCC 5.5.0 sometimes cleverly hoists reads of the pvclock and/or hvclock
      pages before the vclock mode checks.  This creates a path through
      vclock_gettime() in which no vclock is enabled at all (due to disabled
      TSC on old CPUs, for example) but the pvclock or hvclock page
      nevertheless read.  This will segfault on bare metal.
      
      This fixes commit 459e3a21 ("gcc-9: properly declare the
      {pv,hv}clock_page storage") in the sense that, before that commit, GCC
      didn't seem to generate the offending code.  There was nothing wrong
      with that commit per se, and -stable maintainers should backport this to
      all supported kernels regardless of whether the offending commit was
      present, since the same crash could just as easily be triggered by the
      phase of the moon.
      
      On GCC 9.1.1, this doesn't seem to affect the generated code at all, so
      I'm not too concerned about performance regressions from this fix.

      Jon Hunter reports:
        "I have been noticing intermittent failures with a system suspend test on
         some of our machines that have a NFS mounted root file-system. Bisecting
         this issue points to your commit 43123581 ("SUNRPC: Declare RPC
         timers as TIMER_DEFERRABLE") and reverting this on top of v5.2-rc3 does
         appear to resolve the problem.
      
         The cause of the suspend failure appears to be a long delay observed
         sometimes when resuming from suspend, and this is causing our test to
         timeout."
      
      This reverts commit 43123581.

      NFS4: Only set creation opendata if O_CREAT · 90910519
      Benjamin Coddington authored
      We can end up in nfs4_opendata_alloc during task exit, in which case
      current->fs has already been cleaned up.  This leads to a crash in
      current_umask().
      
      Fix this by only setting creation opendata if we are actually doing an open
      with O_CREAT.  We can drop the check for NULL nfs4_open_createattrs, since
      O_CREAT will never be set for the recovery path.

      ARM: 8867/1: vdso: pass --be8 to linker if necessary · c5d0e49e
      Jason A. Donenfeld authored
      The commit fe00e50b ("ARM: 8858/1: vdso: use $(LD) instead of $(CC)
      to link VDSO") removed the passing of CFLAGS, since ld doesn't take
      those directly. However, prior, big-endian ARM was relying on gcc to
      translate its -mbe8 option into ld's --be8 option. Lacking this, ld
      generated be32 code, making the VDSO generate SIGILL when called by
      userspace.
      
      This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled.

         - Make switch to eMMC HS400 more robust for some controllers
         - Add two SDIO func API to manage re-tuning constraints
         - Prevent processing SDIO IRQs when the card is suspended

       "Three fixes that should go into this series.
      
        One is a set of two patches from Christoph, fixing a page leak on same
        page merges. Boiled down version of a bigger fix, but this one is more
        appropriate for this late in the cycle (and easier to backport to
        stable).
      
        The last patch is for a divide error in MD, from Mariusz (via Song)"

      KVM: nVMX: reorganize initial steps of vmx_set_nested_state · 9fd58877
      Paolo Bonzini authored
      Commit 332d0797 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS
      state before setting new state", 2019-05-02) broke evmcs_test because the
      eVMCS setup must be performed even if there is no VMXON region defined,
      as long as the eVMCS bit is set in the assist page.
      
      While the simplest possible fix would be to add a check on
      kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that
      covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly.
      
      Instead, this patch moves checks earlier in the function and
      conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that
      vmx_set_nested_state always goes through vmx_leave_nested
      and nested_enable_evmcs.
      
      Fixes: 332d0797 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS state before setting new state")
