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.

     in-core superblock structure"

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.

Pull GCC plugin updates from Kees Cook:
 "The big part is the randstruct plugin infrastructure.

  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

Pull security layer updates from James Morris:

 - 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.

     * This does _not_ contain any of the newer apparmor mediation
       features/controls (mount, signals, network, keys, ...) that
       Ubuntu is currently carrying, all of which will be RFC'd on top
       of this.

 - Notable also is the Infiniband work in SELinux, and the new file:map
   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.

       Almost all of these changes are the SELinux/IB work done by
       Daniel Jurgens; some other noteworthy changes include a NFS v4.2
       labeling fix, a new file:map permission, and reporting of policy
       capabilities on policy load"

   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.

 - IMA now supports different "ima_appraise=" modes (eg. log, fix) from
   the boot command line.

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.)

net: phy: dp83867: workaround incorrect RX_CTRL pin strap

This patch series adds workaround for incorrect RX_CTRL pin strap
setting that can be found on some TI boards.

This is required to be complaint to PHY datamanual specification.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

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.

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)).

It further advises that if a board has this pin strapped in mode 1 and
mode 2, then to ensure proper operation of the PHY, a software workaround
must be implemented.

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: port enumeration change and FW ABI adjustment

This set changes the way ports are numbered internally to avoid MAC address
changes and invalid link information when breakout is configured.  Second
patch gets rid of old way of looking up MAC addresses in device information
which caused all this confusion.

Patch 3 is a small adjustment to the new FW ABI version we introduced in
this release cycle.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

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.

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.

The function load_bpf_file ignores the return value of
load_and_attach(), so even if load_and_attach() returns an error,
load_bpf_file() will return 0.

Now, load_bpf_file() can call load_and_attach() multiple times and some
can succeed and some could fail. I think the correct behavor is to
return error on the first failed load_and_attach().
