Michael Walle 83216e3988 of: net: pass the dst buffer to of_get_mac_address()
of_get_mac_address() returns a "const void*" pointer to a MAC address.
Lately, support to fetch the MAC address by an NVMEM provider was added.
But this will only work with platform devices. It will not work with
PCI devices (e.g. of an integrated root complex) and esp. not with DSA
ports.

There is an of_* variant of the nvmem binding which works without
devices. The returned data of a nvmem_cell_read() has to be freed after
use. On the other hand the return of_get_mac_address() points to some
static data without a lifetime. The trick for now, was to allocate a
device resource managed buffer which is then returned. This will only
work if we have an actual device.

Change it, so that the caller of of_get_mac_address() has to supply a
buffer where the MAC address is written to. Unfortunately, this will
touch all drivers which use the of_get_mac_address().

Usually the code looks like:

  const char *addr;
  addr = of_get_mac_address(np);
  if (!IS_ERR(addr))
    ether_addr_copy(ndev->dev_addr, addr);

This can then be simply rewritten as:

  of_get_mac_address(np, ndev->dev_addr);

Sometimes is_valid_ether_addr() is used to test the MAC address.
of_get_mac_address() already makes sure, it just returns a valid MAC
address. Thus we can just test its return code. But we have to be
careful if there are still other sources for the MAC address before the
of_get_mac_address(). In this case we have to keep the
is_valid_ether_addr() call.

The following coccinelle patch was used to convert common cases to the
new style. Afterwards, I've manually gone over the drivers and fixed the
return code variable: either used a new one or if one was already
available use that. Mansour Moufid, thanks for that coccinelle patch!

Marek Behún a26c56ae67 ARM: dts: turris-omnia: configure LED[2]/INTn pin as interrupt pin
Use the `marvell,reg-init` DT property to configure the LED[2]/INTn pin
of the Marvell 88E1514 ethernet PHY on Turris Omnia into interrupt mode.

Without this the pin is by default in LED[2] mode, and the Marvell PHY
driver configures LED[2] into "On - Link, Blink - Activity" mode.

This fixes the issue where the pca9538 GPIO/interrupt controller (which
can't mask interrupts in HW) received too many interrupts and after a
time started ignoring the interrupt with error message:
  IRQ 71: nobody cared

There is a work in progress to have the Marvell PHY driver support
parsing PHY LED nodes from OF and registering the LEDs as Linux LED
class devices. Once this is done the PHY driver can also automatically
set the pin into INTn mode if it does not find LED[2] in OF.

Until then, though, we fix this via `marvell,reg-init` DT property.

Arnd Bergmann 28399a5a6d ARM: omap1: fix building with clang IAS
The clang integrated assembler fails to build one file with
a complex asm instruction:

arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: error: invalid instruction, any one of the following would fix this:
 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
 ^
arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: armv6t2
 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
 ^
arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: thumb2
 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
 ^

The problem is that 'NR_IRQS_LEGACY' is not defined here. Apparently
gas does not care because we first add and then subtract this number,
leading to the immediate value to be the same regardless of the
specific definition of NR_IRQS_LEGACY.

Neither the way that 'gas' just silently builds this file, nor the
way that clang IAS makes nonsensical suggestions for how to fix it
is great. Fortunately there is an easy fix, which is to #include
the header that contains the definition.

Carlos Leija b3d09a06d8 ARM: OMAP4: PM: update ROM return address for OSWR and OFF
We need to add a dummy smc call to the cpuidle wakeup path to force the
ROM code to save the return address after MMU is enabled again. This is
needed to prevent random hangs on secure devices like droid4.

Otherwise the system will eventually hang when entering deeper SoC idle
states with the core and mpu domains in open-switch retention (OSWR).
The hang happens as the ROM code tries to use the earlier physical return
address set by omap-headsmp.S with MMU off while waking up CPU1 again.

The hangs started happening in theory already with commit caf8c87d7f
("ARM: OMAP2+: Allow core oswr for omap4"), but in practise the issue went
unnoticed as various drivers were often blocking any deeper idle states
with hardware autoidle features.

This patch is based on an earlier TI Linux kernel tree commit 92f0b3028d9e
("OMAP4: PM: update ROM return address for OSWR and OFF") written by
Carlos Leija <cileija@ti.com>, Praneeth Bajjuri <praneeth@ti.com>, and
Bryan Buckley <bryan.buckley@ti.com>. A later version of the patch was
updated to use CPU_PM notifiers by Tero Kristo <t-kristo@ti.com>.

Fabio Estevam 69cbbf6be5 ARM: imx6ul-14x14-evk: Do not reset the Ethernet PHYs independently
The imx6ul-evk board designer took the bad decision to tie the
two Ethernet PHY reset lines together. This prevents one Ethernet
interface to work while the other one is brought down. For example:

 # ifconfig eth0 down
 # [  279.386551] fec 2188000.ethernet eth1: Link is Down

Bringing eth0 interface down also causes eth1 to be down.

The Ethernet reset lines comes from the IO expander and both come in
logic level 0 by default.

To fix this issue, remove the Ethernet PHY reset descriptions from
its respective PHY nodes and force both Ethernet PHY lines to be at
logic level 1 via gpio-hog.

Using IRQCHIP_DECLARE lets fw_devlink know that it should not wait for
these interrupt controllers to be populated as struct devices. Without
this change, fw_devlink=on will make the consumers of these interrupt
controllers wait for the struct device to be added and thereby block the
consumers' probes forever. Converting to IRQCHIP_DECLARE addresses boot
issues on imx25 with fw_devlink=on that were reported by Martin.

This also removes a lot of boilerplate code.

It's not helpful if every driver has to cook its own. Generalize
xenbus'es INVALID_GRANT_HANDLE and pcifront's INVALID_GRANT_REF (which
shouldn't have expanded to zero to begin with). Use the constants in
p2m.c and gntdev.c right away, and update field types where necessary so
they would match with the constants' types (albeit without touching
struct ioctl_gntdev_grant_ref's ref field, as that's part of the public
interface of the kernel and would require introducing a dependency on
Xen's grant_table.h public header).

Bailing immediately from set_foreign_p2m_mapping() upon a p2m updating
error leaves the full batch in an ambiguous state as far as the caller
is concerned. Instead flags respective slots as bad, unmapping what
was mapped there right away.

HYPERVISOR_grant_table_op()'s return value and the individual unmap
slots' status fields get used only for a one-time - there's not much we
can do in case of a failure.

Note that there's no GNTST_enomem or alike, so GNTST_general_error gets
used.

The map ops' handle fields get overwritten just to be on the safe side.

This is part of XSA-367.

Merge tag 'io_uring-worker.v3-2021-02-25' of git://git.kernel.dk/linux-block

Pull io_uring thread rewrite from Jens Axboe:
 "This converts the io-wq workers to be forked off the tasks in question
  instead of being kernel threads that assume various bits of the
  original task identity.

  This kills > 400 lines of code from io_uring/io-wq, and it's the worst
  part of the code. We've had several bugs in this area, and the worry
  is always that we could be missing some pieces for file types doing
  unusual things (recent /dev/tty example comes to mind, userfaultfd
  reads installing file descriptors is another fun one... - both of
  which need special handling, and I bet it's not the last weird oddity
  we'll find).

  With these identical workers, we can have full confidence that we're
  never missing anything. That, in itself, is a huge win. Outside of
  that, it's also more efficient since we're not wasting space and code
  on tracking state, or switching between different states.

  I'm sure we're going to find little things to patch up after this
  series, but testing has been pretty thorough, from the usual
  regression suite to production. Any issue that may crop up should be
  manageable.

  There's also a nice series of further reductions we can do on top of
  this, but I wanted to get the meat of it out sooner rather than later.
  The general worry here isn't that it's fundamentally broken. Most of
  the little issues we've found over the last week have been related to
  just changes in how thread startup/exit is done, since that's the main
  difference between using kthreads and these kinds of threads. In fact,
  if all goes according to plan, I want to get this into the 5.10 and
  5.11 stable branches as well.

  That said, the changes outside of io_uring/io-wq are:

   - arch setup, simple one-liner to each arch copy_thread()
     implementation.

   - Removal of net and proc restrictions for io_uring, they are no
     longer needed or useful"

Merge tag 'idmapped-mounts-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull idmapped mounts from Christian Brauner:
 "This introduces idmapped mounts which has been in the making for some
  time. Simply put, different mounts can expose the same file or
  directory with different ownership. This initial implementation comes
  with ports for fat, ext4 and with Christoph's port for xfs with more
  filesystems being actively worked on by independent people and
  maintainers.

  Idmapping mounts handle a wide range of long standing use-cases. Here
  are just a few:

   - Idmapped mounts make it possible to easily share files between
     multiple users or multiple machines especially in complex
     scenarios. For example, idmapped mounts will be used in the
     implementation of portable home directories in
     systemd-homed.service(8) where they allow users to move their home
     directory to an external storage device and use it on multiple
     computers where they are assigned different uids and gids. This
     effectively makes it possible to assign random uids and gids at
     login time.

   - It is possible to share files from the host with unprivileged
     containers without having to change ownership permanently through
     chown(2).

   - It is possible to idmap a container's rootfs and without having to
     mangle every file. For example, Chromebooks use it to share the
     user's Download folder with their unprivileged containers in their
     Linux subsystem.

   - It is possible to share files between containers with
     non-overlapping idmappings.

   - Filesystem that lack a proper concept of ownership such as fat can
     use idmapped mounts to implement discretionary access (DAC)
     permission checking.

   - They allow users to efficiently changing ownership on a per-mount
     basis without having to (recursively) chown(2) all files. In
     contrast to chown (2) changing ownership of large sets of files is
     instantenous with idmapped mounts. This is especially useful when
     ownership of a whole root filesystem of a virtual machine or
     container is changed. With idmapped mounts a single syscall
     mount_setattr syscall will be sufficient to change the ownership of
     all files.

   - Idmapped mounts always take the current ownership into account as
     idmappings specify what a given uid or gid is supposed to be mapped
     to. This contrasts with the chown(2) syscall which cannot by itself
     take the current ownership of the files it changes into account. It
     simply changes the ownership to the specified uid and gid. This is
     especially problematic when recursively chown(2)ing a large set of
     files which is commong with the aforementioned portable home
     directory and container and vm scenario.

   - Idmapped mounts allow to change ownership locally, restricting it
     to specific mounts, and temporarily as the ownership changes only
     apply as long as the mount exists.

  Several userspace projects have either already put up patches and
  pull-requests for this feature or will do so should you decide to pull
  this:

   - systemd: In a wide variety of scenarios but especially right away
     in their implementation of portable home directories.

         https://systemd.io/HOME_DIRECTORY/

   - container runtimes: containerd, runC, LXD:To share data between
     host and unprivileged containers, unprivileged and privileged
     containers, etc. The pull request for idmapped mounts support in
     containerd, the default Kubernetes runtime is already up for quite
     a while now: https://github.com/containerd/containerd/pull/4734

   - The virtio-fs developers and several users have expressed interest
     in using this feature with virtual machines once virtio-fs is
     ported.

   - ChromeOS: Sharing host-directories with unprivileged containers.

  I've tightly synced with all those projects and all of those listed
  here have also expressed their need/desire for this feature on the
  mailing list. For more info on how people use this there's a bunch of
  talks about this too. Here's just two recent ones:

      https://www.cncf.io/wp-content/uploads/2020/12/Rootless-Containers-in-Gitpod.pdf
      https://fosdem.org/2021/schedule/event/containers_idmap/

  This comes with an extensive xfstests suite covering both ext4 and
  xfs:

      https://git.kernel.org/brauner/xfstests-dev/h/idmapped_mounts

  It covers truncation, creation, opening, xattrs, vfscaps, setid
  execution, setgid inheritance and more both with idmapped and
  non-idmapped mounts. It already helped to discover an unrelated xfs
  setgid inheritance bug which has since been fixed in mainline. It will
  be sent for inclusion with the xfstests project should you decide to
  merge this.

  In order to support per-mount idmappings vfsmounts are marked with
  user namespaces. The idmapping of the user namespace will be used to
  map the ids of vfs objects when they are accessed through that mount.
  By default all vfsmounts are marked with the initial user namespace.
  The initial user namespace is used to indicate that a mount is not
  idmapped. All operations behave as before and this is verified in the
  testsuite.

  Based on prior discussions we want to attach the whole user namespace
  and not just a dedicated idmapping struct. This allows us to reuse all
  the helpers that already exist for dealing with idmappings instead of
  introducing a whole new range of helpers. In addition, if we decide in
  the future that we are confident enough to enable unprivileged users
  to setup idmapped mounts the permission checking can take into account
  whether the caller is privileged in the user namespace the mount is
  currently marked with.

  The user namespace the mount will be marked with can be specified by
  passing a file descriptor refering to the user namespace as an
  argument to the new mount_setattr() syscall together with the new
  MOUNT_ATTR_IDMAP flag. The system call follows the openat2() pattern
  of extensibility.

  The following conditions must be met in order to create an idmapped
  mount:

   - The caller must currently have the CAP_SYS_ADMIN capability in the
     user namespace the underlying filesystem has been mounted in.

   - The underlying filesystem must support idmapped mounts.

   - The mount must not already be idmapped. This also implies that the
     idmapping of a mount cannot be altered once it has been idmapped.

   - The mount must be a detached/anonymous mount, i.e. it must have
     been created by calling open_tree() with the OPEN_TREE_CLONE flag
     and it must not already have been visible in the filesystem.

  The last two points guarantee easier semantics for userspace and the
  kernel and make the implementation significantly simpler.

  By default vfsmounts are marked with the initial user namespace and no
  behavioral or performance changes are observed.

  The manpage with a detailed description can be found here:

      1d7b902e28

  In order to support idmapped mounts, filesystems need to be changed
  and mark themselves with the FS_ALLOW_IDMAP flag in fs_flags. The
  patches to convert individual filesystem are not very large or
  complicated overall as can be seen from the included fat, ext4, and
  xfs ports. Patches for other filesystems are actively worked on and
  will be sent out separately. The xfstestsuite can be used to verify
  that port has been done correctly.

  The mount_setattr() syscall is motivated independent of the idmapped
  mounts patches and it's been around since July 2019. One of the most
  valuable features of the new mount api is the ability to perform
  mounts based on file descriptors only.

  Together with the lookup restrictions available in the openat2()
  RESOLVE_* flag namespace which we added in v5.6 this is the first time
  we are close to hardened and race-free (e.g. symlinks) mounting and
  path resolution.

  While userspace has started porting to the new mount api to mount
  proper filesystems and create new bind-mounts it is currently not
  possible to change mount options of an already existing bind mount in
  the new mount api since the mount_setattr() syscall is missing.

  With the addition of the mount_setattr() syscall we remove this last
  restriction and userspace can now fully port to the new mount api,
  covering every use-case the old mount api could. We also add the
  crucial ability to recursively change mount options for a whole mount
  tree, both removing and adding mount options at the same time. This
  syscall has been requested multiple times by various people and
  projects.

  There is a simple tool available at

      https://github.com/brauner/mount-idmapped

  that allows to create idmapped mounts so people can play with this
  patch series. I'll add support for the regular mount binary should you
  decide to pull this in the following weeks:

  Here's an example to a simple idmapped mount of another user's home
  directory:

	u1001@f2-vm:/$ sudo ./mount --idmap both:1000:1001:1 /home/ubuntu/ /mnt

	u1001@f2-vm:/$ ls -al /home/ubuntu/

Linus Torvalds 21a6ab2131 Modules updates for v5.12
Summary of modules changes for the 5.12 merge window:
 
 - Retire EXPORT_UNUSED_SYMBOL() and EXPORT_SYMBOL_GPL_FUTURE(). These export
   types were introduced between 2006 - 2008. All the of the unused symbols have
   been long removed and gpl future symbols were converted to gpl quite a long
   time ago, and I don't believe these export types have been used ever since.
   So, I think it should be safe to retire those export types now. (Christoph Hellwig)
 
 - Refactor and clean up some aged code cruft in the module loader (Christoph Hellwig)
 
 - Build {,module_}kallsyms_on_each_symbol only when livepatching is enabled, as
   it is the only caller (Christoph Hellwig)
 
 - Unexport find_module() and module_mutex and fix the last module
   callers to not rely on these anymore. Make module_mutex internal to
   the module loader. (Christoph Hellwig)
 
 - Harden ELF checks on module load and validate ELF structures before checking
   the module signature (Frank van der Linden)
 
 - Fix undefined symbol warning for clang (Fangrui Song)
 
 - Fix smatch warning (Dan Carpenter)

Philip Chen 497c318303 ARM: dts: cros-ec-keyboard: Use keymap macros
The common cros-ec keymap has been defined as macros. This patch uses
the macros to simply linux,keymap in cros-ec-keyboard.dtsi file.

This patch also creates an alias for keyboard-controller to make it
easier to override the keymap in board-specific dts later.

Linus Torvalds 28b9aaac4c This is all driver updates, the majority of which is a bunch of new Qualcomm
clk drivers that dominate the diffstat because we add support for six SoCs from
 that particular vendor. The other big change is the removal of various clk
 drivers that are no longer used now that the kernel is dropping support for
 those SoCs. Beyond that there's the usual non-critical fixes for existing
 drivers and a good number of patches from Lee Jones that cleanup a bunch of W=1
 enabled builds.
 
 Removed Drivers:
  - Remove efm32 clk driver
  - Remove tango4 clk driver
  - Remove zte zx clk driver
  - Remove sirf prima2/atlast clk drivers
  - Remove u300 clk driver
 
 New Drivers:
  - PLL support on MStar/SigmaStar ARMv7 SoCs
  - CPU clks for Qualcomm SDX55
  - GCC and RPMh clks for Qualcomm SC8180x and SC7280 SoCs
  - GCC clks for Qualcomm SM8350
  - GPU clks for Qualcomm SDM660/SDM630
 
 Updates:
  - Video clk fixups on Qualcomm SM8250
  - Improvements for multimedia clks on Qualcomm MSM8998
  - Fix many warnings with W=1 enabled builds under drivers/clk/
  - Support crystal load capacitance for Versaclock VC5
  - Add a "skip recall" DT binding for Silicon Labs' si570 to avoid glitches at boot
  - Convert Xilinx VCU clk driver to a proper clk provider driver
  - Expose Xilinx ZynqMP clk driver to more platforms
  - Amlogic pll driver fixup
  - Amlogic meson8b clock controller dt support clean up
  - Remove mipi clk from the Amlogic axg clock controller
  - New Rockchip rk3368 clock ids related to camera input
  - Use pr_notice() instead of pr_warn() on i.MX6Q pre-boot ldb_di_clk reparenting
  - A series from Liu Ying that adds some SCU clocks support for i.MX8qxp
    DC0/MIPI-LVDS subsystems
  - A series from Lucas Stach that adds PLL monitor clocks for i.MX8MQ, and
    clkout1/2 support for i.MX8MM/MN
  - Add I2c and Ethernet (RAVB) clocks on Renesas R-Car V3U
  - Add timer (TMU) clocks on most Renesas R-Car Gen3 SoCs
  - Add video-related (FCPVD/VSPD/VSPX), watchdog (RWDT), serial
    (HSCIF), pincontrol/GPIO (PFC/GPIO), SPI (MSIOF), SDHI, and DMA
    (SYS-DMAC) clocks on Renesas R-Car V3U
  - Add support for the USB 2.0 clock selector on Renesas RZ/G2 SoCs
  - Allwinner H616 SoC clk support

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "This is all driver updates, the majority of which is a bunch of new
  Qualcomm clk drivers that dominate the diffstat because we add support
  for six SoCs from that particular vendor.

  The other big change is the removal of various clk drivers that are no
  longer used now that the kernel is dropping support for those SoCs.

  Beyond that there's the usual non-critical fixes for existing drivers
  and a good number of patches from Lee Jones that cleanup a bunch of
  W=1 enabled builds.

  Removed Drivers:
   - Remove efm32 clk driver
   - Remove tango4 clk driver
   - Remove zte zx clk driver
   - Remove sirf prima2/atlast clk drivers
   - Remove u300 clk driver

  New Drivers:
   - PLL support on MStar/SigmaStar ARMv7 SoCs
   - CPU clks for Qualcomm SDX55
   - GCC and RPMh clks for Qualcomm SC8180x and SC7280 SoCs
   - GCC clks for Qualcomm SM8350
   - GPU clks for Qualcomm SDM660/SDM630

  Updates:
   - Video clk fixups on Qualcomm SM8250
   - Improvements for multimedia clks on Qualcomm MSM8998
   - Fix many warnings with W=1 enabled builds under drivers/clk/
   - Support crystal load capacitance for Versaclock VC5
   - Add a "skip recall" DT binding for Silicon Labs' si570 to avoid
     glitches at boot
   - Convert Xilinx VCU clk driver to a proper clk provider driver
   - Expose Xilinx ZynqMP clk driver to more platforms
   - Amlogic pll driver fixup
   - Amlogic meson8b clock controller dt support clean up
   - Remove mipi clk from the Amlogic axg clock controller
   - New Rockchip rk3368 clock ids related to camera input
   - Use pr_notice() instead of pr_warn() on i.MX6Q pre-boot ldb_di_clk
     reparenting
   - A series from Liu Ying that adds some SCU clocks support for
     i.MX8qxp DC0/MIPI-LVDS subsystems
   - A series from Lucas Stach that adds PLL monitor clocks for i.MX8MQ,
     and clkout1/2 support for i.MX8MM/MN
   - Add I2c and Ethernet (RAVB) clocks on Renesas R-Car V3U
   - Add timer (TMU) clocks on most Renesas R-Car Gen3 SoCs
   - Add video-related (FCPVD/VSPD/VSPX), watchdog (RWDT), serial
     (HSCIF), pincontrol/GPIO (PFC/GPIO), SPI (MSIOF), SDHI, and DMA
     (SYS-DMAC) clocks on Renesas R-Car V3U
   - Add support for the USB 2.0 clock selector on Renesas RZ/G2 SoCs
   - Allwinner H616 SoC clk support"
