RDMA/mlx5: Fix mkey cache WQ flush
The cited patch tries to ensure no pending works on the mkey cache
workqueue by disabling adding new works and call flush_workqueue().
But this workqueue also has delayed works which might still be pending
the delay time to be queued.
Add cancel_delayed_work() for the delayed works which waits to be queued
and then the flush_workqueue() will flush all works which are already
queued and running.

LoongArch KVM changes for v6.7
Add LoongArch's KVM support. Loongson 3A5000/3A6000 supports hardware
assisted virtualization. With cpu virtualization, there are separate
hw-supported user mode and kernel mode in guest mode. With memory
virtualization, there are two-level hw mmu table for guest mode and host
mode. Also there is separate hw cpu timer with consant frequency in
guest mode, so that vm can migrate between hosts with different freq.
Currently, we are able to boot LoongArch Linux Guests.
Few key aspects of KVM LoongArch added by this series are:
1. Enable kvm hardware function when kvm module is loaded.
2. Implement VM and vcpu related ioctl interface such as vcpu create,
vcpu run etc. GET_ONE_REG/SET_ONE_REG ioctl commands are use to
get general registers one by one.
3. Hardware access about MMU, timer and csr are emulated in kernel.
4. Hardwares such as mmio and iocsr device are emulated in user space
such as IPI, irqchips, pci devices etc.

certs: Only allow certs signed by keys on the builtin keyring
Originally the secondary trusted keyring provided a keyring to which extra keys may be added, provided those keys were not blacklisted and were vouched for by a key built into the kernel or already in the secondary trusted keyring. On systems with the machine keyring configured, additional keys may also be vouched for by a key on the machine keyring. Prevent loading additional certificates directly onto the secondary keyring, vouched for by keys on the machine keyring, yet allow these certificates to be loaded onto other trusted keyrings.

ima: annotate iint mutex to avoid lockdep false positive warnings
It is not clear that IMA should be nested at all, but as long is it measures files both on overlayfs and on underlying fs, we need to annotate the iint mutex to avoid lockdep false positives related to IMA + overlayfs, same as overlayfs annotates the inode mutex.

erofs: fix erofs_insert_workgroup() lockref usage
As Linus pointed out [1], lockref_put_return() is fundamentally
designed to be something that can fail. It behaves as a fastpath-only
thing, and the failure case needs to be handled anyway.
Actually, since the new pcluster was just allocated without being
populated, it won't be accessed by others until it is inserted into
XArray, so lockref helpers are actually unneeded here.
Let's just set the proper reference count on initializing.

Rust changes for v6.7
A small one compared to the previous one in terms of features. In terms
of lines, as usual, the 'alloc' version upgrade accounts for most of them.
Toolchain and infrastructure:
- Upgrade to Rust 1.73.0.
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. They contain the fixes for
a few issues we reported to the Rust project.
In addition, a few cleanups indicated by the upgraded compiler
or possible thanks to it. For instance, the compiler now detects
redundant explicit links.
- A couple changes to the Rust 'Makefile' so that it can be used with
toybox tools, allowing Rust to be used in the Android kernel build.
x86:
- Enable IBT if enabled in C.
Documentation:
- Add "The Rust experiment" section to the Rust index page.
MAINTAINERS
- Add Maintainer Entry Profile field ('P:').
- Update our 'W:' field to point to the webpage we have been building
this year.

Traditionally linkers only did this for .bss and it was always the last segment. As a result, the kernel only handled this case when it was the last segment. We've had two recent cases where linkers were trying to use these kinds of segments for other reasons, and the were in the middle of the segment list. There was no good reason for the kernel not to support this, and the refactor actually ends up making things more readable too. - Enable namespaced binfmt_misc Christian Brauner has made it possible to use binfmt_misc with mount namespaces. This means some traditionally root-only interfaces (for adding/removing formats) are now more exposed (but believed to be safe). - Remove struct tag 'dynamic' from ELF UAPI Alejandro Colomar noticed that the ELF UAPI has been polluting the struct namespace with an unused and overly generic tag named "dynamic" for no discernible reason for many many years.

RCU pull request for v6.7
This pull request contains the following branches:
rcu/torture: RCU torture, locktorture and generic torture infrastructure
updates that include various fixes, cleanups and consolidations.
Among the user visible things, ftrace dumps can now be found into
their own file, and module parameters get better documented and
reported on dumps.
rcu/fixes: Generic and misc fixes all over the place. Some highlights:
* Hotplug handling has seen some light cleanups and comments.
* An RCU barrier can now be triggered through sysfs to serialize
memory stress testing and avoid OOM.
* Object information is now dumped in case of invalid callback
invocation.
* Also various SRCU issues, too hard to trigger to deserve urgent
pull requests, have been fixed.
rcu/docs: RCU documentation updates
rcu/refscale: RCU reference scalability test minor fixes and doc
improvements.
rcu/tasks: RCU tasks minor fixes
rcu/stall: Stall detection updates. Introduce RCU CPU Stall notifiers
that allows a subsystem to provide informations to help debugging.
Also cure some false positive stalls.

CSD lock commits for v6.7
This series adds a kernel boot parameter that causes the kernel to panic if one of the call_smp_function() APIs is stalled for more than the specified duration. This is useful in deployments in which a clean panic is preferable to an indefinite stall. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmU9plITHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jB91D/9OiOMtV03TXN2K+zGmJMjTFgLuVnug OqG4mrCv7jTJ3k6fTpu7hih/BCmG1Mu7byyPV6BUSfKsYony7L4yTPFJsjK8lNmq MHh847DErGieuURCDnsvqBVpYIRfXnvW9ptlf+BMCjbzz4FuUu1XhJTm+U2nab3i BEIEMORxDCyghh7yluAVG6sULRXOqjv5VcypwOXUbavDf0JyJTns4QlXFD85yiBr nvfHvLUrzu5EblA3m09lTnCaKrAlz5pwD7fWQq7bS3rz2gndR/DcVcZknQ68FMsj Mcf0Zf45TzyWWfMcE8LCulhMlZ2GYsIm2YkIbgwlsOAndjBrV55rsgaVbSZDke37 QMHPGUZ7m7AjuDqpWZITrJjQHkWCtn/5tFSazHSlMwWg44pgOqvc3OgZn04tzn01 L/guq3yBIKBJiAjdgzdx8/H9S7cSH8TLEWFY2utEAMIjef9Xzi6qwQ4X5p4K9QYJ Sm1hTTCbF9NeyMk0o2rokR58f13+9ewxE4RIYcwP9loo6nbBcTVN/fvdHN6jQywa 7UIui508AUf55zQgO+5z8LsmjyNiDmDIeE8CLeVDicllWN+ne7F//AXAuA5V8m+y G0Mphn/lZpnddDSFlR/QFuMvGqtpIu2y8w93awq8g/VzirbkiiCia3iFcFtss4ip n0Y50CCu/W70fw== =ZD0S -----END PGP SIGNATURE----- Merge tag 'csd-lock.2023.10.23a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull CSD lock update from Paul McKenney: "This adds a kernel boot parameter that causes the kernel to panic if one of the call_smp_function() APIs is stalled for more than the specified duration.

X86 core code updates:
- Limit the hardcoded topology quirk for Hygon CPUs to those which have a
model ID less than 4. The newer models have the topology CPUID leaf 0xB
correctly implemented and are not affected.
- Make SMT control more robust against enumeration failures
SMT control was added to allow controlling SMT at boottime or
runtime. The primary purpose was to provide a simple mechanism to
disable SMT in the light of speculation attack vectors.
It turned out that the code is sensible to enumeration failures and
worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration
which means the primary thread mask is not set up correctly. By chance
a XEN/PV boot ends up with smp_num_siblings == 2, which makes the
hotplug control stay at its default value "enabled". So the mask is
never evaluated.
The ongoing rework of the topology evaluation caused XEN/PV to end up
with smp_num_siblings == 1, which sets the SMT control to "not
supported" and the empty primary thread mask causes the hotplug core to
deny the bringup of the APS.
Make the decision logic more robust and take 'not supported' and 'not
implemented' into account for the decision whether a CPU should be
booted or not.
- Fake primary thread mask for XEN/PV
Pretend that all XEN/PV vCPUs are primary threads, which makes the
usage of the primary thread mask valid on XEN/PV. That is consistent
with because all of the topology information on XEN/PV is fake or even
non-existent.
- Encapsulate topology information in cpuinfo_x86
Move the randomly scattered topology data into a separate data
structure for readability and as a preparatory step for the topology
evaluation overhaul.
- Consolidate APIC ID data type to u32
It's fixed width hardware data and not randomly u16, int, unsigned long
or whatever developers decided to use.
- Cure the abuse of cpuinfo for persisting logical IDs.
Per CPU cpuinfo is used to persist the logical package and die
IDs. That's really not the right place simply because cpuinfo is
subject to be reinitialized when a CPU goes through an offline/online
cycle.
Use separate per CPU data for the persisting to enable the further
topology management rework. It will be removed once the new topology
management is in place.
- Provide a debug interface for inspecting topology information
Useful in general and extremly helpful for validating the topology
management rework in terms of correctness or "bug" compatibility.

Updates for the X86 APIC:
- Make the quirk for non-maskable MSI interrupts in the affinity setter
functional again.
It was broken by a MSI core code update, which restructured the code in
a way that the quirk flag was not longer set correctly.
Trying to restore the core logic caused a deeper inspection and it
turned out that the extra quirk flag is not required at all because
it's the inverse of the reservation mode bit, which only can be set
when the MSI interrupt is maskable.
So the trivial fix is to use the reservation mode check in the affinity
setter function and remove almost 40 lines of code related to the
no-mask quirk flag.
- Cure a Kconfig dependency issue which causes compile fails by correcting
the conditionals in the affected heaer files.
- Clean up coding style in the UV APIC driver.

Update for time, timekeeping and timers:
Core:
- Avoid superfluous deactivation of the tick in the low resolution tick
NOHZ interrupt handler as the deactivation is handled already in the
idle loop and on interrupt exit.
- Update stale comments in the tick NOHZ code and rename the tick
handler functions to be self-explanatory.
- Remove an unused function in the tick NOHZ code, which was forgotten
when the last user went away.
- Handle RTC alarms which exceed the maximum alarm time of the
underlying RTC hardware gracefully.
Setting RTC alarms which exceed the maximum alarm time of the RTC
hardware failed so far and caused suspend operations to abort.
Cure this by limiting the alarm to the maximum alarm time of the RTC
hardware, which is provided by the driver. This causes early resume
wakeups, but that's way better than not suspending at all.
Drivers:
- Add a proper clocksource/event driver for the ancient Cirrus Logic
EP93xx SoC family, which is one of the last non device-tree holdouts
in arch/arm.
- The usual boring device tree bindings updates and small fixes and
enhancements all over the place.

Updates for SMP and CPU hotplug:
- Switch the smp_call_function*() @csd argument to call_single_data_t
type, which is a cache-line aligned typedef of the underlying struct
__call_single_data.
This ensures that the call data is not crossing a cacheline which
avoids bouncing an extra cache-line for the SMP function call
- Prevent offlining of the last housekeeping CPU when CPU isolation is
active.
Offlining the last housekeeping CPU makes no sense in general, but also
caused the scheduler to panic due to the empty CPU mask when rebuilding
the scheduler domains.
- Remove an unused CPU hotplug state

Updates for the interrupt subsytem:
Core:
- Exclude managed interrupts in the calculation of interrupts which are
targeted to a CPU which is about to be offlined to ensure that there
are enough free vectors on the still online CPUs to migrate them over.
Managed interrupts do not need to be accounted because they are
either shut down on offline or migrated to an already reserved and
guaranteed slot on a still online CPU in the interrupts affinity
mask.
Including managed interrupts is overaccounting and can result in
needlessly aborting hibernation on large server machines.
- The usual set of small improvements
Drivers:
- Make the generic interrupt chip implementation handle interrupt
domains correctly and initialize the name pointers correctly
- Add interrupt affinity setting support to the Renesas RZG2L chip
driver.
- Prevent registering syscore operations multiple times in the SiFive
PLIC chip driver.
- Update device tree handling in the NXP Layerscape MSI chip driver

Two small updates to ptrace_stop():
- Add a comment to explain that the preempt_disable() before unlocking
tasklist lock is not a correctness problem and just avoids the tracer
to preempt the tracee before the tracee schedules out.
- Make that preempt_disable() conditional on PREEMPT_RT=n.
RT enabled kernels cannot disable preemption at this point because
cgroup_enter_frozen() and sched_submit_work() acquire spinlocks or
rwlocks which are substituted by sleeping locks on RT. Acquiring a
sleeping lock in a preemption disable region is obviously not possible.
This obviously brings back the potential slowdown of ptrace() for RT
enabled kernels, but that's a price to be payed for latency guarantees.

This commit adds mount option 'zero_size_dir'. If this option enabled, don't allocate a cluster to directory when creating it, and set the directory size to 0. On Windows, a cluster is allocated for a directory when it is created, so the mount option is disabled by default.

exfat: support handle zero-size directory
After repairing a corrupted file system with exfatprogs' fsck.exfat, zero-size directories may result. It is also possible to create zero-size directories in other exFAT implementation, such as Paragon ufsd dirver. As described in the specification, the lower directory size limits is 0 bytes. Without this commit, sub-directories and files cannot be created under a zero-size directory, and it cannot be removed.

exfat: add ioctls for accessing attributes
Add GET and SET attributes ioctls to enable attribute modification. We already do this in FAT and a few userspace utils made for it would benefit from this also working on exFAT, namely fatattr. Signed-off-by: Jan Cincera <hcincera@gmail.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> |
