      compiler, clang: always inline when CONFIG_OPTIMIZE_INLINING is disabled · 9a04dbcf
      David Rientjes authored
      The motivation for commit abb2ea7d ("compiler, clang: suppress
      warning for unused static inline functions") was to suppress clang's
      warnings about unused static inline functions.
      
      For configs without CONFIG_OPTIMIZE_INLINING enabled, such as any non-x86
      architecture, `inline' in the kernel implies that
      __attribute__((always_inline)) is used.
      
      Some code depends on that behavior, see
        https://lkml.org/lkml/2017/6/13/918:
      
        net/built-in.o: In function `__xchg_mb':
        arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99'
        arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99
      
      The full fix would be to identify these breakages and annotate the
      functions with __always_inline instead of `inline'.  But since we are
      late in the 4.12-rc cycle, simply carry forward the forced inlining
      behavior and work toward moving arm64, and other architectures, toward
      CONFIG_OPTIMIZE_INLINING behavior.

       - Waiman made the debug controller work and a lot more useful on
         cgroup2
      
       - There were a couple issues with cgroup subtree delegation. The
         documentation on delegating to a non-root user was missing some part
         and cgroup namespace support wasn't factoring in delegation at all.
         The documentation is updated and the now there is a mount option to
         make cgroup namespace fit for delegation

      Pull mnt namespace updates from Eric Biederman:
       "A big break-through came during this development cycle as a way was
        found to maintain the existing umount -l semantics while allowing for
        optimizations that improve the performance. That is represented by the
        first change in this series moving the reparenting of mounts into
        their own pass. This has allowed addressing the horrific performance
        of umount -l on a carefully crafted tree of mounts with locks held
        (0.06s vs 60s in my testing). What allowed this was not changing where
        umounts propagate to while propgating umounts.
      
        The next change fixes the case where the order of the mount whose
        umount are being progated visits a tree where the mounts are stacked
        upon each other in another order. This is weird but not hard to
        implement.
      
        The final change takes advantage of the unchanging mount propgation
        tree to skip parts of the mount propgation tree that have already been
        visited. Yielding a very nice speed up in the worst case.
      
        There remains one outstanding question about the semantics of umount -l
        that I am still discussiong with Ram Pai. In practice that area of the
        semantics was changed by 1064f874 ("mnt: Tuck mounts under others
        instead of creating shadow/side mounts.") and no regressions have been
        reported. Still I intend to finish talking that out with him to ensure
        there is not something a more intense use of mount propagation in the
        future will not cause to become significant"

      Pull GFS2 updates from Bob Peterson:
       "We've got eight GFS2 patches for this merge window:
      
         - Andreas Gruenbacher has four patches related to cleaning up the
           GFS2 inode evict process. This is about half of his patches
           designed to fix a long-standing GFS2 hang related to the inode
           shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
           memory and blocks on the shrinker.
      
           These four patches have been well tested. His second set of patches
           are still being tested, so I plan to hold them until the next merge
           window, after we have more weeks of testing. The first patch
           eliminates the flush_delayed_work, which can block.
      
         - Andreas's second patch protects setting of gl_object for rgrps with
           a spin_lock to prevent proven races.
      
         - His third patch introduces a centralized mechanism for queueing
           glock work with better reference counting, to prevent more races.
      
          -His fourth patch retains a reference to inode glocks when an error
           occurs while creating an inode. This keeps the subsequent evict
           from needing to reacquire the glock, which might call into DLM and
           block in low memory conditions.
      
         - Arvind Yadav has a patch to add const to attribute_group
           structures.
      
         - I have a patch to detect directory entry inconsistencies and
           withdraw the file system if any are found. Better that than silent
           corruption.
      
         - I have a patch to remove a vestigial variable from glock
           structures, saving some slab space.
      
         - I have another patch to remove a vestigial variable from the GFS2
           in-core superblock structure"

      Cavium CNN55XX: fix broken default Kconfig entry · b4b8cbf6
      Linus Torvalds authored
      
      
      Every developer always thinks that _their_ code is so special and
      magical that it should be enabled by default.
      
      And most of them are completely and utterly wrong.  That's definitely
      the case when you write a specialty driver for a very unsual "security
      processor". It does *not* get to mark itself as "default m".
      
      If you solve world hunger, and make a driver that cures people of
      cancer, by all means enable it by default.  But afaik, the Cavium
      CNN55XX does neither.

        This is the first of two expected pull requests for randstruct since
        there are dependencies in other trees that would be easier to merge
        once those have landed. Notably, the IPC allocation refactoring in
        -mm, and many trivial merge conflicts across several trees when
        applying the __randomize_layout annotation.
      
        As a result, it seemed like I should send this now since it is
        relatively self-contained, and once the rest of the trees have landed,
        send the annotation patches. I'm expecting the final phase of
        randstruct (automatic struct selection) will land for v4.14, but if
        its other tree dependencies actually make it for v4.13, I can send

       - a major update for AppArmor. From JJ:
      
           * several bug fixes and cleanups
      
           * the patch to add symlink support to securityfs that was floated
             on the list earlier and the apparmorfs changes that make use of
             securityfs symlinks
      
           * it introduces the domain labeling base code that Ubuntu has been
             carrying for several years, with several cleanups applied. And it
             converts the current mediation over to using the domain labeling
             base, which brings domain stacking support with it. This finally
             will bring the base upstream code in line with Ubuntu and provide
             a base to upstream the new feature work that Ubuntu carries.

         permission. From Paul:
      
            "While we're down to 21 patches for v4.13 (it was 31 for v4.12),
             the diffstat jumps up tremendously with over 2k of line changes.

             labeling fix, a new file:map permission, and reporting of policy

         There's also now genfscon labeling support for tracefs, which was
         lost in v4.1 with the separation from debugfs.
      
       - Smack incorporates a safer socket check in file_receive, and adds a
         cap_capable call in privilege check.
      
       - TPM as usual has a bunch of fixes and enhancements.
      
       - Multiple calls to security_add_hooks() can now be made for the same
         LSM, to allow LSMs to have hook declarations across multiple files.

      gfs2: Get rid of flush_delayed_work in gfs2_evict_inode · 4fd1a579
      Andreas Gruenbacher authored
      
      
      So far, gfs2_evict_inode clears gl->gl_object and then flushes the glock
      work queue to make sure that inode glops which dereference gl->gl_object
      have finished running before the inode is destroyed.  However, flushing
      the work queue may do more work than needed, and in particular, it may
      call into DLM, which we want to avoid here.  Use a bit lock
      (GIF_GLOP_PENDING) to synchronize between the inode glops and
      gfs2_evict_inode instead to get rid of the flushing.
      
      In addition, flush the work queues of existing glocks before reusing
      them for new inodes to get those glocks into a known state: the glock
      state engine currently doesn't handle glock re-appropriation correctly.
      (We may be able to fix the glock state engine instead later.)

      The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
      advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
      supported (see note below Table 5 (4-Level Strap Pins)).
      
      There are some boards which have the pin strapped this way and need
      software workaround suggested by the data manual. Bit[7] of
      Configuration Register 4 (address 0x0031) must be cleared to 0. This
      ensures proper operation of the PHY.
      
      Implement driver support for device-tree property meant to advertise
      the wrong strapping.

      Since it is not possible to detect in software if RX_DV/RX_CTRL pin is
      incorrectly strapped, add a device-tree property for the board to
      advertise this and allow corrective action in software.

      nfp: default to chained metadata prepend format · 64a919a9
      Jakub Kicinski authored
      ABI 4.x introduced the chained metadata format and made it the
      only one possible.  There are cases, however, where the old
      format is preferred - mostly to make interoperation with VFs
      using ABI 3.x easier for the datapath.  In ABI 5.x we allowed
      for more flexibility by selecting the metadata format based
      on capabilities.  The default was left to non-chained.
      
      In case of fallback traffic, there is no capability telling the
      driver there may be chained metadata.  With a very stripped-
      -down FW the default old metadata format would be selected
      making the driver drop all fallback traffic.
      
      This patch changes the default selection in the driver. It
      should not hurt with old firmwares, because if they don't
      advertise RSS they will not produce metadata anyway.  New
      firmwares advertising ABI 5.x, however, can depend on the
      driver defaulting to chained format.

      The legacy MAC address lookup doesn't work well with breakout
      cables.  We are probably better off picking random addresses
      than the wrong ones in the theoretical scenario where management
      FW didn't tell us what the port config is.

      nfp: improve order of interfaces in breakout mode · 2eb333c4
      Jakub Kicinski authored
      For historical reasons we enumerate the vNICs in order.  This means
      that if user configures breakout on a multiport card, the first
      interface of the second port will have its MAC address changed.
      
      What's worse, when moved from static information (HWInfo) to using
      management FW (NSP), more features started depending on the port ids.
      Right now in case of breakout first subport of the second port and
      second subport of the first port will have their link info swapped.
      
      Revise the ordering scheme so that first subport maintains its address.
      Side effect of this change is that we will use base lane ids in
      devlink (i.e. 40G ports will be 4 ids apart), e.g.:
      
      pci/0000:04:00.0/0: type eth netdev p6p1
      pci/0000:04:00.0/4: type eth netdev p6p2
      
      Note that behaviour of phys_port_id is not changed since there is
      a separate id number for the subport there.
