Aleksa Sarai fddb5d430a open: introduce openat2(2) syscall
/* Background. */
For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].

This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).

Userspace also has a hard time figuring out whether a particular flag is
supported on a particular kernel. While it is now possible with
contemporary kernels (thanks to [3]), older kernels will expose unknown
flag bits through fcntl(F_GETFL). Giving a clear -EINVAL during
openat(2) time matches modern syscall designs and is far more
fool-proof.

In addition, the newly-added path resolution restriction LOOKUP flags
(which we would like to expose to user-space) don't feel related to the
pre-existing O_* flag set -- they affect all components of path lookup.
We'd therefore like to add a new flag argument.

Adding a new syscall allows us to finally fix the flag-ignoring problem,
and we can make it extensible enough so that we will hopefully never
need an openat3(2).

/* Syscall Prototype. */
  /*
   * open_how is an extensible structure (similar in interface to
   * clone3(2) or sched_setattr(2)). The size parameter must be set to
   * sizeof(struct open_how), to allow for future extensions. All future
   * extensions will be appended to open_how, with their zero value
   * acting as a no-op default.
   */
  struct open_how { /* ... */ };

  int openat2(int dfd, const char *pathname,
              struct open_how *how, size_t size);

/* Description. */
The initial version of 'struct open_how' contains the following fields:

  flags
    Used to specify openat(2)-style flags. However, any unknown flag
    bits or otherwise incorrect flag combinations (like O_PATH|O_RDWR)
    will result in -EINVAL. In addition, this field is 64-bits wide to
    allow for more O_ flags than currently permitted with openat(2).

  mode
    The file mode for O_CREAT or O_TMPFILE.

    Must be set to zero if flags does not contain O_CREAT or O_TMPFILE.

  resolve
    Restrict path resolution (in contrast to O_* flags they affect all
    path components). The current set of flags are as follows (at the
    moment, all of the RESOLVE_ flags are implemented as just passing
    the corresponding LOOKUP_ flag).

    RESOLVE_NO_XDEV       => LOOKUP_NO_XDEV
    RESOLVE_NO_SYMLINKS   => LOOKUP_NO_SYMLINKS
    RESOLVE_NO_MAGICLINKS => LOOKUP_NO_MAGICLINKS
    RESOLVE_BENEATH       => LOOKUP_BENEATH
    RESOLVE_IN_ROOT       => LOOKUP_IN_ROOT

open_how does not contain an embedded size field, because it is of
little benefit (userspace can figure out the kernel open_how size at
runtime fairly easily without it). It also only contains u64s (even
though ->mode arguably should be a u16) to avoid having padding fields
which are never used in the future.

Note that as a result of the new how->flags handling, O_PATH|O_TMPFILE
is no longer permitted for openat(2). As far as I can tell, this has
always been a bug and appears to not be used by userspace (and I've not
seen any problems on my machines by disallowing it). If it turns out
this breaks something, we can special-case it and only permit it for
openat(2) but not openat2(2).

After input from Florian Weimer, the new open_how and flag definitions
are inside a separate header from uapi/linux/fcntl.h, to avoid problems
that glibc has with importing that header.

/* Testing. */
In a follow-up patch there are over 200 selftests which ensure that this
syscall has the correct semantics and will correctly handle several
attack scenarios.

In addition, I've written a userspace library[4] which provides
convenient wrappers around openat2(RESOLVE_IN_ROOT) (this is necessary
because no other syscalls support RESOLVE_IN_ROOT, and thus lots of care
must be taken when using RESOLVE_IN_ROOT'd file descriptors with other
syscalls). During the development of this patch, I've run numerous
verification tests using libpathrs (showing that the API is reasonably
usable by userspace).

/* Future Work. */
Additional RESOLVE_ flags have been suggested during the review period.
These can be easily implemented separately (such as blocking auto-mount
during resolution).

Furthermore, there are some other proposed changes to the openat(2)
interface (the most obvious example is magic-link hardening[5]) which
would be a good opportunity to add a way for userspace to restrict how
O_PATH file descriptors can be re-opened.

Another possible avenue of future work would be some kind of
CHECK_FIELDS[6] flag which causes the kernel to indicate to userspace
which openat2(2) flags and fields are supported by the current kernel
(to avoid userspace having to go through several guesses to figure it
out).

Linus Torvalds 45763bf4bc Char/Misc driver patches for 5.1-rc1
Here is the big char/misc driver patch pull request for 5.1-rc1.
 
 The largest thing by far is the new habanalabs driver for their AI
 accelerator chip.  For now it is in the drivers/misc directory but will
 probably move to a new directory soon along with other drivers of this
 type.
 
 Other than that, just the usual set of individual driver updates and
 fixes.  There's an "odd" merge in here from the DRM tree that they asked
 me to do as the MEI driver is starting to interact with the i915 driver,
 and it needed some coordination.  All of those patches have been
 properly acked by the relevant subsystem maintainers.
 
 All of these have been in linux-next with no reported issues, most for
 quite some time.

Hans-Christian Noren Egtvedt 26202873bb avr32: remove support for AVR32 architecture
This patch drops support for AVR32 architecture from the Linux kernel.

The AVR32 architecture is not keeping up with the development of the
kernel, and since it shares so much of the drivers with Atmel ARM SoC,
it is starting to hinder these drivers to develop swiftly.

Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
Microchip).

Finally, the GCC toolchain is stuck at version 4.2.x, and has not
received any patches since the last release from Atmel;
4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this
toolchain is no longer able to properly link the network stack.

Haavard and I have came to the conclusion that we feel keeping AVR32 on
life support offers more obstacles for Atmel ARMs, than it gives joy to
AVR32 users. I also suspect there are very few AVR32 users left today,
if anybody at all.

Linus Torvalds 991bc36254 Merge branch 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 microcode update from Ingo Molnar:
 "The biggest change (by Borislav Petkov) is a thorough rewrite of the
  Intel microcode loader and its interactions with the core code.

  The biggest conceptual change is the decoupling of the microcode
  loading on boot and application processors (which load the microcode
  in different scenarios), so that both parse the input patches with as
  few assumptions as possible - this also fixes various kernel address
  space randomization bugs. (The AP side then goes on and caches the
  result to improve boot performance.)

  Since the AMD side already did this, this change also opened up the
  path towards more unification/simplification of the core microcode
  loading infrastructure:

     10 files changed, 647 insertions(+), 940 deletions(-)

  which speaks for itself"

Linus Torvalds ed8d747fd2 Fix up a couple of field names in the CREDITS file
Ozgur Karatas reported that the very first entry in the CREDITS file had
the wrong tag for name (M: instead of N: - it happened when moving the
entry from the MAINTAINERS file, where 'M:' stands for "Maintainer").

And when I went looking, I found a couple of other cases of wrong
tagging too.

Linus Torvalds 88a99886c2 This is the bulk of pin control changes for the v4.3 development
cycle
 
 Core changes:
 
 - It is possible configure groups in debugfs.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a
   combined call to irq_set_chained_handler_and_data(). This
   series was created by Thomas Gleixner after the problem was
   observed by Russell King.
 
 - Tglx also made another series of patches switching
   __irq_set_handler_locked() for irq_set_handler_locked() which
   is way cleaner.
 
 - Tglx also wrote a good bunch of patches to make use of
   irq_desc_get_xxx() accessors and avoid looking up irq_descs
   from IRQ numbers. The goal is to get rid of the irq number
   from the handlers in the IRQ flow which is nice.
 
 Driver feature enhancements:
 
 - Power management support for the SiRF SoC Atlas 7.
 
 - Power down support for the Qualcomm driver.
 
 - Intel Cherryview and Baytrail: switch drivers to use raw
   spinlocks in IRQ handlers to play nice with the realtime
   patch set.
 
 - Rework and new modes handling for Qualcomm SPMI-MPP.
 
 - Pinconf power source config for SH PFC.
 
 New drivers and subdrivers:
 
 - A new driver for Conexant Digicolor CX92755.
 
 - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8,
   PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support.
 
 - Reverse-egineered the S/PDIF settings for the Allwinner
   sun4i driver.
 
 - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
 
 - A new Freescale i.mx6ul subdriver.
 
 Cleanup:
 
 - Remove platform data support in a number of SH PFC
   subdrivers.

Merge tag 'pinctrl-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.3 development

  Like with GPIO it's a lot of stuff.  If my subsystems are any sign of
