      Pull keys updates from James Morris:
       "Provide five new operations in the key_type struct that can be used to
        provide access to asymmetric key operations. These will be implemented
        for the asymmetric key type in a later patch and may refer to a key
        retained in RAM by the kernel or a key retained in crypto hardware.
      
           int (*asym_query)(const struct kernel_pkey_params *params,
                             struct kernel_pkey_query *info);
           int (*asym_eds_op)(struct kernel_pkey_params *params,
                              const void *in, void *out);
           int (*asym_verify_signature)(struct kernel_pkey_params *params,
                                        const void *in, const void *in2);
      
        Since encrypt, decrypt and sign are identical in their interfaces,
        they're rolled together in the asym_eds_op() operation and there's an
        operation ID in the params argument to distinguish them.
      
        Verify is different in that we supply the data and the signature
        instead and get an error value (or 0) as the only result on the
        expectation that this may well be how a hardware crypto device may
        work"

      of: Fix cpu node iterator to not ignore disabled cpu nodes · c961cb3b
      Rob Herring authored
      In most cases, nodes with 'status = "disabled";' are treated as if the
      node is not present though it is a common bug to forget to check that.
      However, cpu nodes are different in that "disabled" simply means offline
      and the OS can bring the CPU core online. Commit f1f207e4 ("of: Add
      cpu node iterator for_each_of_cpu_node()") followed the common behavior
      of ignoring disabled cpu nodes. This breaks some powerpc systems (at
      least NXP P50XX/e5500). Fix this by dropping the status check.
      
      Fixes: 651d44f9 ("of: use for_each_of_cpu_node iterator")
      Fixes: f1f207e4 ("of: Add cpu node iterator for_each_of_cpu_node()")

      ovl: automatically enable redirect_dir on metacopy=on · d47748e5
      Miklos Szeredi authored
      Current behavior is to automatically disable metacopy if redirect_dir is
      not enabled and proceed with the mount.
      
      If "metacopy=on" mount option was given, then this behavior can confuse the
      user: no mount failure, yet metacopy is disabled.
      
      This patch makes metacopy=on imply redirect_dir=on.
      
      The converse is also true: turning off full redirect with redirect_dir=
      {off|follow|nofollow} will disable metacopy.
      
      If both metacopy=on and redirect_dir={off|follow|nofollow} is specified,
      then mount will fail, since there's no way to correctly resolve the
      conflict.

      Linus Torvalds authored
      Pull stackleak gcc plugin from Kees Cook:
       "Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin
        was ported from grsecurity by Alexander Popov. It provides efficient
        stack content poisoning at syscall exit. This creates a defense
        against at least two classes of flaws:
      
         - Uninitialized stack usage. (We continue to work on improving the
           compiler to do this in other ways: e.g. unconditional zero init was
           proposed to GCC and Clang, and more plugin work has started too).
      
         - Stack content exposure. By greatly reducing the lifetime of valid
           stack contents, exposures via either direct read bugs or unknown
           cache side-channels become much more difficult to exploit. This
           complements the existing buddy and heap poisoning options, but
           provides the coverage for stacks.
      
        The x86 hooks are included in this series (which have been reviewed by
        Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already
        been merged through the arm64 tree (written by Laura Abbott and
        reviewed by Mark Rutland and Will Deacon).
      
        With VLAs having been removed this release, there is no need for
        alloca() protection, so it has been removed from the plugin"

      net: stmmac: Fix stmmac_mdio_reset() when building stmmac as modules · 30549aab
      Niklas Cassel authored
      When building stmmac, it is only possible to select CONFIG_DWMAC_GENERIC,
      or any of the glue drivers, when CONFIG_STMMAC_PLATFORM is set.
      The only exception is CONFIG_STMMAC_PCI.
      
      When calling of_mdiobus_register(), it will call our ->reset()
      callback, which is set to stmmac_mdio_reset().
      
      Most of the code in stmmac_mdio_reset() is protected by a
      "#if defined(CONFIG_STMMAC_PLATFORM)", which will evaluate
      to false when CONFIG_STMMAC_PLATFORM=m.
      
      Because of this, the phy reset gpio will only be pulled when
      stmmac is built as built-in, but not when built as modules.
      
      Fix this by using "#if IS_ENABLED()" instead of "#if defined()".

      ====================
      Intel Wired LAN Driver Updates 2018-10-31
      
      This series contains a various collection of fixes.
      
      Miroslav Lichvar from Red Hat or should I say IBM now?  Updates the PHC
      timecounter interval for igb so that it gets updated at least once
      every 550 seconds.
      
      Ngai-Mint provides a fix for fm10k to prevent a soft lockup or system
      crash by adding a new condition to determine if the SM mailbox is in the
      correct state before proceeding.
      
      Jake provides several fm10k fixes, first one marks complier aborts as
      non-fatal since on some platforms trigger machine check errors when the
      compile aborts.  Added missing device ids to the in-kernel driver.  Due
      to the recent fixes, bumped the driver version.
      
      I (Jeff Kirsher) fixed a XFRM_ALGO dependency for both ixgbe and
      ixgbevf.  This fix was based on the original work from Arnd Bergmann,
      which only fixed ixgbe.
      
      Mitch provides a fix for i40e/avf to update the status codes, which
      resolves an issue between a mis-match between i40e and the iavf driver,
      which also supports the ice LAN driver.
      
      Radoslaw fixes the ixgbe where the driver is logging a message about
      spoofed packets detected when the VF is re-started with a different MAC
      address.

      The following pull-request contains BPF updates for your *net* tree.
      
      The main changes are:
      
      1) Fix tcp_bpf_recvmsg() to return -EAGAIN instead of 0 in non-blocking
         case when no data is available yet, from John.
      
      2) Fix a compilation error in libbpf_attach_type_by_name() when compiled
         with clang 3.8, from Andrey.
      
      3) Fix a partial copy of map pointer on scalar alu and remove id
         generation for RET_PTR_TO_MAP_VALUE return types, from Daniel.
      
      4) Add unlimited memlock limit for kernel selftest's flow_dissector_load
         program, from Yonghong.
      
      5) Fix ping for some BPF shell based kselftests where distro does not
         ship "ping -6" anymore, from Li.
