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.

RISC-V Patches for the 5.12 Merge Window
I have a handful of new RISC-V related patches for this merge window: * A check to ensure drivers are properly using uaccess. This isn't manifesting with any of the drivers I'm currently using, but may catch errors in new drivers. * Some preliminary support for the FU740, along with the HiFive Unleashed it will appear on. * NUMA support for RISC-V, which involves making the arm64 code generic. * Support for kasan on the vmalloc region. * A handful of new drivers for the Kendryte K210, along with the DT plumbing required to boot on a handful of K210-based boards. * Support for allocating ASIDs. * Preliminary support for kernels larger than 128MiB. * Various other improvements to our KASAN support, including the utilization of huge pages when allocating the KASAN regions. We may have already found a bug with the KASAN_VMALLOC code, but it's passing my tests. There's a fix in the works, but that will probably miss the merge window. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmA4hXATHHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYifryD/0SfXGOfj93Cxq7I7AYhhzCN7lJ5jvv iEQScTlPqU9nfvYodo4EDq0fp+5LIPpTL/XBHtqVjzv0FqRNa28Ea0K7kO8HuXc4 BaUd0m/DqyB4Gfgm4qjc5bDneQ1ZYxVXprYERWNQ5Fj+tdWhaQGOW64N/TVodjjj NgJtTqbIAcjJqjUtttM8TZN5U1TgwLo+KCqw3iYW12lV1YKBBuvrwvSdD6jnFdIQ AzG/wRGZhxLoFxgBB/NEsZxDoSd6ztiwxLhS9lX4okZVsryyIdOE70Q/MflfiTlU xE+AdxQXTMUiiqYSmHeDD6PDb57GT/K3hnjI1yP+lIZpbInsi29JKow1qjyYjfHl 9cSSKYCIXHL7jKU6pgt34G1O5N5+fgqHQhNbfKvlrQ2UPlfs/tWdKHpFIP/z9Jlr 0vCAou7NSEB9zZGqzO63uBLXoN8yfL8FT3uRnnRvoRpfpex5dQX2QqPLQ7327D7N GUG31nd1PHTJPdxJ1cI4SO24PqPpWDWY9uaea+0jv7ivGClVadZPco/S3ZKloguT lazYUvyA4oRrSAyln785Rd8vg4CinqTxMtIyZbRMbNkgzVQARi9a8rjvu4n9qms2 2wlXDFi8nR8B4ih5n79dSiiLM9ay9GJDxMcf9VxIxSAYZV2fJALnpK6gV2fzRBUe +k/uv8BIsFmlwQ== =CutX -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-5.12-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V updates from Palmer Dabbelt: "A handful of new RISC-V related patches for this merge window: - A check to ensure drivers are properly using uaccess.

arm64: kasan: simplify and inline MTE functions
This change provides a simpler implementation of mte_get_mem_tag(), mte_get_random_tag(), and mte_set_mem_tag_range(). Simplifications include removing system_supports_mte() checks as these functions are onlye called from KASAN runtime that had already checked system_supports_mte(). Besides that, size and address alignment checks are removed from mte_set_mem_tag_range(), as KASAN now does those. This change also moves these functions into the asm/mte-kasan.h header and implements mte_set_mem_tag_range() via inline assembly to avoid unnecessary functions calls.

kfence: use pt_regs to generate stack trace on faults
Instead of removing the fault handling portion of the stack trace based on the fault handler's name, just use struct pt_regs directly. Change kfence_handle_page_fault() to take a struct pt_regs, and plumb it through to kfence_report_error() for out-of-bounds, use-after-free, or invalid access errors, where pt_regs is used to generate the stack trace. If the kernel is a DEBUG_KERNEL, also show registers for more information.

arm64, kfence: enable KFENCE for ARM64
Add architecture specific implementation details for KFENCE and enable KFENCE for the arm64 architecture. In particular, this implements the required interface in <asm/kfence.h>. KFENCE requires that attributes for pages from its memory pool can individually be set. Therefore, force the entire linear map to be mapped at page granularity. Doing so may result in extra memory allocated for page tables in case rodata=full is not set; however, currently CONFIG_RODATA_FULL_DEFAULT_ENABLED=y is the default, and the common case is therefore not affected by this change.

arm64: stacktrace: Report when we reach the end of the stack
Currently the arm64 unwinder code returns -EINVAL whenever it can't find the next stack frame, not distinguishing between cases where the stack has been corrupted or is otherwise in a state it shouldn't be and cases where we have reached the end of the stack. At the minute none of the callers care what error code is returned but this will be important for reliable stack trace which needs to be sure that the stack is intact. Change to return -ENOENT in the case where we reach the bottom of the stack. The error codes from this function are only used in kernel, this particular code is chosen as we are indicating that we know there is no frame there.

kasan, arm64: allow using KUnit tests with HW_TAGS mode
On a high level, this patch allows running KUnit KASAN tests with the hardware tag-based KASAN mode. Internally, this change reenables tag checking at the end of each KASAN test that triggers a tag fault and leads to tag checking being disabled. Also simplify is_write calculation in report_tag_fault. With this patch KASAN tests are still failing for the hardware tag-based mode; fixes come in the next few patches.

Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for 5.12-rc1. Over time it seems like this tree is collecting more and more tiny driver subsystems in one place, making it easier for those maintainers, which is why this is getting larger. Included in here are: - coresight driver updates - habannalabs driver updates - virtual acrn driver addition (proper acks from the x86 maintainers) - broadcom misc driver addition - speakup driver updates - soundwire driver updates - fpga driver updates - amba driver updates - mei driver updates - vfio driver updates - greybus driver updates - nvmeem driver updates - phy driver updates - mhi driver updates - interconnect driver udpates - fsl-mc bus driver updates - random driver fix - some small misc driver updates (rtsx, pvpanic, etc.) All of these have been in linux-next for a while, with the only reported issue being a merge conflict in include/linux/mod_devicetable.h that you will hit in your tree due to the dfl_device_id addition from the fpga subsystem in here.

arm64: Add missing ISB after invalidating TLB in enter_vhe
Although there has been a bit of back and forth on the subject, it
appears that invalidating TLBs requires an ISB instruction after the
TLBI/DSB sequence when FEAT_ETS is not implemented by the CPU.
From the bible:
| In an implementation that does not implement FEAT_ETS, a TLB
| maintenance instruction executed by a PE, PEx, can complete at any
| time after it is issued, but is only guaranteed to be finished for a
| PE, PEx, after the execution of DSB by the PEx followed by a Context
| synchronization event
Add the missing ISB in enter_vhe(), just in case.

arm64: VHE: Enable EL2 MMU from the idmap
Enabling the MMU requires the write to SCTLR_ELx (and the ISB
that follows) to live in some identity-mapped memory. Otherwise,
the translation will result in something totally unexpected
(either fetching the wrong instruction stream, or taking a
fault of some sort).
This is exactly what happens in mutate_to_vhe(), as this code
lives in the .hyp.text section, which isn't identity-mapped.
With the right configuration, this explodes badly.
Extract the MMU-enabling part of mutate_to_vhe(), and move
it to its own function that lives in the idmap. This ensures
nothing bad happens.

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.

As usual, a number of additional device drivers that were added to the kernel are now enabled in the respective configuration files. A few of the files get updated to match the current Kconfig files for removed or renamed options.

SoC platform removal
There are a lot of platforms that have not seen any interesting code changes in the past five years or more. I made a list and asked around which ones are no longer in use [1], and received confirmation about six ARM platforms and the TI C6x architecture that have all reached the end of their life upstream, with no known users remaining: - efm32 -- added in 2011, first Cortex-M, no notable changes after 2013 - picoxcell -- added in 2011, abandoned after 2012 acquisition - prima2 -- added in 20111, no notable changes since 2015 - tango -- added in 2015, sporadic changes until 2017, but abandoned - u300 -- added in 2009, no notable changes since 2013 - zx --added in 2015 for both 32, 2017 for 64 bit, no notable changes - arch/c6x -- added in 2011, but work stalled soon after that A number of other platforms on the original list turned out to still have users. In some cases there are out-of-tree patches and users that plan to contribute them in the future, in other cases the code is complete and works reliably.

arm64 module: set plt* section addresses to 0x0
These plt* and .text.ftrace_trampoline sections specified for arm64 have
non-zero addressses. Non-zero section addresses in a relocatable ELF would
confuse GDB when it tries to compute the section offsets and it ends up
printing wrong symbol addresses. Therefore, set them to zero, which mirrors
the change in commit

arm64: spectre: Prevent lockdep splat on v4 mitigation enable path
The Spectre-v4 workaround is re-configured when resuming from suspend,
as the firmware may have re-enabled the mitigation despite the user
previously asking for it to be disabled.
Enabling or disabling the workaround can result in an undefined
instruction exception on CPUs which implement PSTATE.SSBS but only allow
it to be configured by adjusting the SPSR on exception return. We handle
this by installing an 'undef hook' which effectively emulates the access.
Installing this hook requires us to take a couple of spinlocks both to
avoid corrupting the internal list of hooks but also to ensure that we
don't run into an unhandled exception. Unfortunately, when resuming from
suspend, we haven't yet called rcu_idle_exit() and so lockdep gets angry
about "suspicious RCU usage". In doing so, it tries to print a warning,
which leads it to get even more suspicious, this time about itself:
| rcu_scheduler_active = 2, debug_locks = 1
| RCU used illegally from extended quiescent state!

arm64: mte: Allow PTRACE_PEEKMTETAGS access to the zero page
The ptrace(PTRACE_PEEKMTETAGS) implementation checks whether the user
page has valid tags (mapped with PROT_MTE) by testing the PG_mte_tagged
page flag. If this bit is cleared, ptrace(PTRACE_PEEKMTETAGS) returns
-EIO.
A newly created (PROT_MTE) mapping points to the zero page which had its
tags zeroed during cpu_enable_mte(). If there were no prior writes to
this mapping, ptrace(PTRACE_PEEKMTETAGS) fails with -EIO since the zero
page does not have the PG_mte_tagged flag set.
Set PG_mte_tagged on the zero page when its tags are cleared during
boot. In addition, to avoid ptrace(PTRACE_PEEKMTETAGS) succeeding on
!PROT_MTE mappings pointing to the zero page, change the
__access_remote_tags() check to (vm_flags & VM_MTE) instead of
PG_mte_tagged.
