Linus Torvalds e24dd9ee53 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
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.

Linus Torvalds 7391786a64 Merge branch 'stable-4.13' of git://git.infradead.org/users/pcmoore/audit
Pull audit updates from Paul Moore:
 "Things are relatively quiet on the audit front for v4.13, just five
  patches for a total diffstat of 102 lines.

  There are two patches from Richard to consistently record the POSIX
  capabilities and add the ambient capability information as well.

  I also chipped in two patches to fix a race condition with the auditd
  tracking code and ensure we don't skip sending any records to the
  audit multicast group.

  Finally a single style fix that I accepted because I must have been in
  a good mood that day.

  Everything passes our test suite, and should be relatively harmless,
  please merge for v4.13"

Andreas Gruenbacher 4fd1a57952 gfs2: Get rid of flush_delayed_work in gfs2_evict_inode
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.)

Based on a patch by Steven Whitehouse <swhiteho@redhat.com>.

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.

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.

This set changes the way ports are numbered internally to avoid MAC address

Jakub Kicinski 64a919a944 nfp: default to chained metadata prepend format
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.

Jakub Kicinski 2eb333c4b4 nfp: improve order of interfaces in breakout mode
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.

Linus Torvalds a9ceea2674 ARM: 64-bit DT updates
Device-tree updates for arm64 platforms. For the first time I can
 remember, this is actually larger than the corresponding branch for
 32-bit platforms overall, though that has more individual changes.
 
 A significant portion this time is due to added machine support:
 
 - Initial support for the Realtek RTD1295 SoC, along with the Zidoo
   X9S set-top-box
 
 - Initial support for Actions Semi S900 and the Bubblegum-96
   single-board-cёmputer.
 
 - Rockchips support for the rk3399-Firefly single-board-computer
   gets added, this one stands out for being relatively fast,
   affordable and well₋supported, compared to many boards that
   only fall into one or two of the above categories.
 
 - Mediatek gains support for the mt6797 mobile-phone SoC platform
   and corresponding evaluation board.
 
 - Amlogic board support gets added for the NanoPi K2 and S905x
   LibreTech CC single-board computers and the R-Box Pro set-top-box
 
 - Allwinner board support gets added for the OrangePi Win,
   Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single
   board computers and the SoPine system-on-module.
 
 - Renesas board support for Salvator-XS and H3ULCB
   automotive development systems.
 
 - Socionext Uniphier board support for LD11-global and LD20-global,
   whatever those may be.
 
 - Broadcom adds support for the new Stingray communication processor
   in its iProc family, along with two reference boards.
 
 Other updates include:

Merge tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM 64-bit DT updates from Arnd Bergmann:
 "Device-tree updates for arm64 platforms. For the first time I can
  remember, this is actually larger than the corresponding branch for
  32-bit platforms overall, though that has more individual changes.

  A significant portion this time is due to added machine support:

   - Initial support for the Realtek RTD1295 SoC, along with the Zidoo
     X9S set-top-box

   - Initial support for Actions Semi S900 and the Bubblegum-96
     single-board-cёmputer.

   - Rockchips support for the rk3399-Firefly single-board-computer gets
     added, this one stands out for being relatively fast, affordable
     and well₋supported, compared to many boards that only fall into one
     or two of the above categories.

   - Mediatek gains support for the mt6797 mobile-phone SoC platform and
     corresponding evaluation board.

   - Amlogic board support gets added for the NanoPi K2 and S905x
     LibreTech CC single-board computers and the R-Box Pro set-top-box

   - Allwinner board support gets added for the OrangePi Win, Orangepi
     Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single board computers
     and the SoPine system-on-module.

   - Renesas board support for Salvator-XS and H3ULCB automotive
     development systems.

   - Socionext Uniphier board support for LD11-global and LD20-global,
     whatever those may be.

   - Broadcom adds support for the new Stingray communication processor
     in its iProc family, along with two reference boards.

  Other updates include:

   - For the hisicon platform, support for Hi3660-Hikey960 gets extended
     significantly.

   - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,

Linus Torvalds 1849f800fb ARM: Device-tree updates
Device-tree continues to see lots of updates. The majority of patches
 here are smaller changes for new hardware on existing platforms, and
 there are a few larger changes worth pointing out.
 
 New machines:
 
 - The new Action Semi S500 platform is added along with initial
   support for the LeMaker Guitar board.
 
 - STM32 gains support for three new boards: stm32h743-disco,
   stm32f746-disco, and stm32f769-disco, along with new device
   support for the existing stm32f429 boards.
 
 - Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H
   with 10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module
   plus board.
 
 - On Marvell "mvebu", we gain support for the Linksys WRT3200ACM
   wireless router.
 
 - For NXP i.MX, we gain support for the Gateworks Ventana GW5600
   and the Technexion Pico i.MX7D single-board computers.
 
 - The BeagleBone Blue is added for OMAP, it's the latest variation
   of the popular Beaglebone Black single-board computer.
 
 - The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards
   are added, these are the latest variations of a seemingly endless
   supply of similar single-board computers.
 
 Other updates:
 
 - Linus Walleij improves support for the "Faraday" based SoC platforms
   from various SoC makers (Moxart, Aspeed, Gemini)
 
 - The ARM Mali GPU is now describe on Rockchips SoCs
 
 - Mediatek MT7623 is extended significantly, making it much
   more useful.
 
 - Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom,
   Allwinner, Qualcomm, iMX
 
 - For Amlogic, the clock support is extended a lot on meson8b.
 
 - We now build the devicetree file for the Raspberry Pi 3 on 32-bit
   ARM, in addition to the existing ARM64 support, to help users
   wanting to run a 32-bit system on it.

David S. Miller dcc13ee85f Merge branch 'net-subsystem-misc-refcounter-conversions'
Elena Reshetova says:

====================
v2 net subsystem misc refcounter conversions

Changes in v2:
 * rebase on top of net-next
 * currently by default refcount_t = atomic_t (*) and uses all
   atomic standard operations unless CONFIG_REFCOUNT_FULL is enabled.
   This is a compromise for the systems that are critical on
   performance (such as net) and cannot accept even slight delay
   on the refcounter operations.

This series, for various misc network components, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.
These are the last networking-related conversions with the exception of
network drivers (to be send separately).

Please excuse the long patch set, but seems like breaking it up
won't save that much on CC list and most of the changes are
trivial.

The patches are fully independent and can be cherry-picked separately.
In order to try with refcount functionality enabled in run-time,
CONFIG_REFCOUNT_FULL must be enabled.

NOTE: automatic kernel builder for some reason doesn't like all my
network branches and regularly times out the builds on these branches.
Suggestion for "waiting a day for a good coverage" doesn't work, as
we have seen with generic network conversions. So please wait for the
full report from kernel test rebot before merging further up.
This has been compile-tested in 116 configs, but 71 timed out (including
all s390-related configs again). I am trying to see if they can fix
build coverage for me in meanwhile.

* The respective change is currently merged into -next as
  "locking/refcount: Create unchecked atomic_t implementation".
