s390/decompressor: add link map saving
Produce arch/s390/boot/vmlinux.map link map for the decompressor, when CONFIG_VMLINUX_MAP option is enabled. Link map is quite useful during making kernel changes related to how the decompressor is composed and debugging linker scripts.

s390/smp: perform cpu reset before delegating work to target cpu
Clear CPU state (e.g. all TLB entries, prefetched instructions, etc.) of the target CPU, however without clearing register contents before starting any work on it. This puts the target CPU in a more defined state compared to the current Stop + Restart sigp orders. Signed-off-by: Heiko Carstens <hca@linux.ibm.com> |

s390/mcck: cleanup user process termination path
If a machine check interrupt hits while user process is running __s390_handle_mcck() helper function is called directly from the interrupt handler and terminates the current process by calling make_task_dead() routine. The make_task_dead() is not allowed to be called from interrupt context which forces the machine check handler switch to the kernel stack and enable local interrupts first. The __s390_handle_mcck() could also be called to service pending work, but this time from the external interrupts handler. It is the machine check handler that establishes the work and schedules the external interrupt, therefore the machine check interrupt itself should be disabled while reading out the corresponding variable: local_mcck_disable(); mcck = *this_cpu_ptr(&cpu_mcck); memset(this_cpu_ptr(&cpu_mcck), 0, sizeof(mcck)); local_mcck_enable(); However, local_mcck_disable() does not have effect when __s390_handle_mcck() is called directly form the machine check handler, since the machine check interrupt is still disabled. Therefore, it is not the opening bracket to the following local_mcck_enable() function. Simplify the user process termination flow by scheduling the external interrupt and killing the affected process from the interrupt context. Assume a kernel-generated signal is always delivered and ignore a value returned by do_send_sig_info() funciton.

s390/cpum_sf: use READ_ONCE_ALIGNED_128() instead of 128-bit cmpxchg
Use READ_ONCE_ALIGNED_128() to read the previous value in front of a 128-bit cmpxchg loop, instead of (mis-)using a 128-bit cmpxchg operation to do the same. This makes the code more readable and is faster. Link: https://lore.kernel.org/r/20230224100237.3247871-3-hca@linux.ibm.com Signed-off-by: Heiko Carstens <hca@linux.ibm.com> |

s390/rwonce: add READ_ONCE_ALIGNED_128() macro
Add an s390 specific READ_ONCE_ALIGNED_128() helper, which can be used for fast block concurrent (atomic) 128-bit accesses. The used lpq instruction requires 128-bit alignment. This is also the reason why the compiler doesn't emit this instruction if __READ_ONCE() is used for 128-bit accesses.

s390/ap,zcrypt,vfio: introduce and use ap_queue_status_reg union
Introduce a new ap queue status register wrapper union to access register wide values. So the inline assembler only sees register wide values but the surrounding code may use a more structured view of the same value and a reader of the code (and the compiler) gets a clear understanding about the mapping between fields and register values. All the changes to access the ap queue status are local to the inline functions within ap.h. However, the struct ap_qirq_ctrl has been replaces by a union for same reason and this needed slight adaptions in the calling code.

s390/nmi: fix virtual-physical address confusion
When a machine check is received while in SIE, it is reinjected into the guest in some cases. The respective code needs to access the sie_block, which is taken from the backed up R14. Since reinjection only occurs while we are in SIE (i.e. between the labels sie_entry and sie_leave in entry.S and thus if CIF_MCCK_GUEST is set), the backed up R14 will always contain a physical address in s390_backup_mcck_info. This currently works, because virtual and physical addresses are the same. Add phys_to_virt() to resolve the virtual-physical confusion.

s390/setup: do not complain about parameters handled in decompressor
Currently there are several kernel command line parameters which are only parsed and handled in decompressor and not known to the kernel. This leads to the following error message during kernel boot: Unknown kernel command line parameters "mem=3G nokaslr", will be passed to user space. To avoid confusion, register those parameters with an empty stub so that kernel does not complain about them.

Networking changes for 6.3.
Core
----
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used
to describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols
---------
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF
---
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
to better support decap on GRE tunnel devices not operating
in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk
and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols
by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter
---------
- Remove the CLUSTERIP target. It has been marked as obsolete
for years, and we still have WARN splats wrt. races of
the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to
the existing 'delete' commands, but do not return an error if
the referenced object (set, chain, rule...) did not exist.
Driver API
----------
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into multiple
files, drop some of the unnecessarily granular locks and factor out
common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
interface instead.
- Improve the CAN bit timing configuration. Use extack to return error
messages directly to user space, update the SJW handling, including
the definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit architectural register (ZT0, for the look-up table feature) that Linux needs to save/restore. - Include TPIDR2 in the signal context and add the corresponding kselftests. - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG (ARM CMN) at probe time. - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64. - Permit EFI boot with MMU and caches on. Instead of cleaning the entire loaded kernel image to the PoC and disabling the MMU and caches before branching to the kernel bare metal entry point, leave the MMU and caches enabled and rely on EFI's cacheable 1:1 mapping of all of system RAM to populate the initial page tables. - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64 kernel (the arm32 kernel only defines the values). - Harden the arm64 shadow call stack pointer handling: stash the shadow stack pointer in the task struct on interrupt, load it directly from this structure. - Signal handling cleanups to remove redundant validation of size information and avoid reading the same data from userspace twice. - Refactor the hwcap macros to make use of the automatically generated ID registers. It should make new hwcaps writing less error prone. - Further arm64 sysreg conversion and some fixes. - arm64 kselftest fixes and improvements. - Pointer authentication cleanups: don't sign leaf functions, unify asm-arch manipulation. - Pseudo-NMI code generation optimisations. - Minor fixes for SME and TPIDR2 handling. - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic shadow call stack in two passes, intercept pfn changes in set_pte_at() without the required break-before-make sequence, attempt to dump all instructions on unhandled kernel faults. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmP0/QsACgkQa9axLQDI XvG+gA/+JDVEH9wRzAIZvbp9hSuohPc48xgAmIMP1eiVB0/5qeRjYAJwS33H0rXS BPC2kj9IBy/eQeM9ICg0nFd0zYznSVacITqe6NrqeJ1F+ftS4rrHdfxd+J7kIoCs V2L8e+BJvmHdhmNV2qMAgJdGlfxfQBA7fv2cy52HKYcouoOh1AUVR/x+yXVXAsCd qJP3+dlUKccgm/oc5unEC1eZ49u8O+EoasqOyfG6K5udMgzhEX3K6imT9J3hw0WT UjstYkx5uGS/prUrRCQAX96VCHoZmzEDKtQuHkHvQXEYXsYPF3ldbR2CziNJnHe7 QfSkjJlt8HAtExA+BkwEe9i0MQO/2VF5qsa2e4fA6l7uqGu3LOtS/jJd23C9n9fR Id8aBMeN6S8+MjqRA9L2uf4t6e4ISEHoG9ZRdc4WOwloxEEiJoIeun+7bHdOSZLj AFdHFCz4NXiiwC0UP0xPDI2YeCLqt5np7HmnrUqwzRpVO8UUagiJD8TIpcBSjBN9 J68eidenHUW7/SlIeaMKE2lmo8AUEAJs9AorDSugF19/ThJcQdx7vT2UAZjeVB3j 1dbbwajnlDOk/w8PQC4thFp5/MDlfst0htS3WRwa+vgkweE2EAdTU4hUZ8qEP7FQ smhYtlT1xUSTYDTqoaG/U2OWR6/UU79wP0jgcOsHXTuyYrtPI/Q= =VmXL -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Support for arm64 SME 2 and 2.1.

s390 updates for 6.3 merge window
- Large cleanup of the con3270/tty3270 driver. Among others this fixes:
* Background Color Support
* ASCII Line Character Support
* VT100 Support
* Geometries other than 80x24
- Cleanup and improve cmpxchg() code. Also add cmpxchg_user_key() to
uaccess functions, which will be used by KVM to access KVM guest memory
with a specific storage key.
- Add support for user space events counting to CPUMF.
- Cleanup the vfio/ccw code, which also allows now to properly support 2K
Format-2 IDALs.
- Move kernel page table allocation and initialization to decompressor,
which finally allows to enter the kernel with dynamic address translation
enabled. This in turn allows to get rid of code with special handling in
the kernel, which has to distinguish if DAT is on or off.
- Replace kretprobe with rethook.
- Various improvements to vfio/ap queue resets:
* Use TAPQ to verify completion of a reset in progress rather than
multiple invocations of ZAPQ.
* Check TAPQ response codes when verifying successful completion of ZAPQ.
* Fix erroneous handling of some error response codes.
* Increase the maximum amount of time to wait for successful completion
of ZAPQ.
- Rework system call wrappers to get rid of alias functions, which were
only left on s390.
- Cleanup diag288_wdt watchdog driver. It has been agreed on with Guenter
Roeck that this goes upstream via the s390 tree.
- Add missing loadparm parameter handling for list-directed ECKD ipl/reipl.
- Various improvements to memory detection code.
- Remove arch_cpu_idle_time() since the current implementation is broken,
and allows user space observable accounted idle times which can
temporarily decrease.
- Add Reset DAT-Protection support: (only) allow to change PTEs from RO to
RW with a new RDP instruction. Unlike the currently used IPTE
instruction, this does not necessarily guarantee that TLBs of all CPUs
are synchronously flushed; and that remote CPUs can see spurious
protection faults. The overall improvement for not requiring an all CPU
synchronization, like it is required with IPTE, should be beneficial.
- Fix KFENCE page fault reporting.
- Smaller cleanups and improvement all over the place.

uaccess: Add speculation barrier to copy_from_user()
The results of "access_ok()" can be mis-speculated. The result is that you can end speculatively: if (access_ok(from, size)) // Right here even for bad from/size combinations. On first glance, it would be ideal to just add a speculation barrier to "access_ok()" so that its results can never be mis-speculated. But there are lots of system calls just doing access_ok() via "copy_to_user()" and friends (example: fstat() and friends). Those are generally not problematic because they do not _consume_ data from userspace other than the pointer. They are also very quick and common system calls that should not be needlessly slowed down. "copy_from_user()" on the other hand uses a user-controller pointer and is frequently followed up with code that might affect caches. Take something like this: if (!copy_from_user(&kernelvar, uptr, size)) do_something_with(kernelvar); If userspace passes in an evil 'uptr' that *actually* points to a kernel addresses, and then do_something_with() has cache (or other) side-effects, it could allow userspace to infer kernel data values. Add a barrier to the common copy_from_user() code to prevent mis-speculated values which happen after the copy. Also add a stub for architectures that do not define barrier_nospec(). This makes the macro usable in generic code. Since the barrier is now usable in generic code, the x86 #ifdef in the BPF code can also go away.

Pull thermal control updates from Rafael Wysocki:
"The majority of changes here are related to the general switch-over to
using arrays of generic trip point structures registered along with a
thermal zone instead of trip point callbacks (this has been done
mostly by Daniel Lezcano with some help from yours truly on the Intel
drivers front).
Apart from that and the related reorganization of code, there are some
enhancements of the existing driver and a new Mediatek Low Voltage
Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
rework so it will use the generic idle_inject facility for CPU idle
time injection going forward and it will take additional module
parameters for specifying the subset of CPUs to be affected by it
(work done by Srinivas Pandruvada).
Also included are assorted fixes and a whole bunch of cleanups.

Pull ACPI updates from Rafael Wysocki:
"These fix a frequency limit issue in the ACPI processor performance
library code, fix a few issues in the ACPICA code, improve Crystal
Cove support in the ACPI PMIC driver, fix string handling in the ACPI
battery driver, add IRQ override quirks for a few machines more, fix
other assorted problems and clean up code and documentation.

RCU pull request for v6.3
This pull request contains the following branches:
doc.2023.01.05a: Documentation updates.
fixes.2023.01.23a: Miscellaneous fixes, perhaps most notably:
o Throttling callback invocation based on the number of callbacks
that are now ready to invoke instead of on the total number
of callbacks.
o Several patches that suppress false-positive boot-time
diagnostics, for example, due to lockdep not yet being
initialized.
o Make expedited RCU CPU stall warnings dump stacks of any tasks
that are blocking the stalled grace period. (Normal RCU CPU
stall warnings have doen this for mnay years.)
o Lazy-callback fixes to avoid delays during boot, suspend, and
resume. (Note that lazy callbacks must be explicitly enabled,
so this should not (yet) affect production use cases.)
kvfree.2023.01.03a: Cause kfree_rcu() and friends to take advantage of
polled grace periods, thus reducing memory footprint by almost
two orders of magnitude, admittedly on a microbenchmark.
This series also begins the transition from kfree_rcu(p) to
kfree_rcu_mightsleep(p). This transition was motivated by bugs
where kfree_rcu(p), which can block, was typed instead of the
intended kfree_rcu(p, rh).
srcu.2023.01.03a: SRCU updates, perhaps most notably fixing a bug that
causes SRCU to fail when booted on a system with a non-zero boot
CPU. This surprising situation actually happens for kdump kernels
on the powerpc architecture. It also adds an srcu_down_read()
and srcu_up_read(), which act like srcu_read_lock() and
srcu_read_unlock(), but allow an SRCU read-side critical section
to be handed off from one task to another.
srcu-always.2023.02.02a: Cleans up the now-useless SRCU Kconfig option.
There are a few more commits that are not yet acked or pulled
into maintainer trees, and these will be in a pull request for
a later merge window.
tasks.2023.01.03a: RCU-tasks updates, perhaps most notably these fixes:
o A strange interaction between PID-namespace unshare and the
RCU-tasks grace period that results in a low-probability but
very real hang.
o A race between an RCU tasks rude grace period on a single-CPU
system and CPU-hotplug addition of the second CPU that can result
in a too-short grace period.
o A race between shrinking RCU tasks down to a single callback list
and queuing a new callback to some other CPU, but where that
queuing is delayed for more than an RCU grace period. This can
result in that callback being stranded on the non-boot CPU.
torture.2023.01.05a: Torture-test updates and fixes.
torturescript.2023.01.03a: Torture-test scripting updates and fixes.
stall.2023.01.09a: Provide additional RCU CPU stall-warning information
in kernels built with CONFIG_RCU_CPU_STALL_CPUTIME=y, and
restore the full five-minute timeout limit for expedited RCU
CPU stall warnings.

stall warnings have done this for many years)
- Lazy-callback fixes to avoid delays during boot, suspend, and
resume. (Note that lazy callbacks must be explicitly enabled, so
this should not (yet) affect production use cases)
- Make kfree_rcu() and friends take advantage of polled grace periods,
thus reducing memory footprint by almost two orders of magnitude,
admittedly on a microbenchmark
This also begins the transition from kfree_rcu(p) to
kfree_rcu_mightsleep(p). This transition was motivated by bugs where
kfree_rcu(p), which can block, was typed instead of the intended
kfree_rcu(p, rh)
- SRCU updates, perhaps most notably fixing a bug that causes SRCU to
fail when booted on a system with a non-zero boot CPU. This
surprising situation actually happens for kdump kernels on the
powerpc architecture
This also adds an srcu_down_read() and srcu_up_read(), which act like
srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side
critical section to be handed off from one task to another
- Clean up the now-useless SRCU Kconfig option
There are a few more commits that are not yet acked or pulled into
maintainer trees, and these will be in a pull request for a later
merge window
- RCU-tasks updates, perhaps most notably these fixes:
- A strange interaction between PID-namespace unshare and the
RCU-tasks grace period that results in a low-probability but
very real hang
- A race between an RCU tasks rude grace period on a single-CPU
system and CPU-hotplug addition of the second CPU that can
result in a too-short grace period
- A race between shrinking RCU tasks down to a single callback
list and queuing a new callback to some other CPU, but where
that queuing is delayed for more than an RCU grace period. This
can result in that callback being stranded on the non-boot CPU
- Torture-test updates and fixes
- Torture-test scripting updates and fixes
- Provide additional RCU CPU stall-warning information in kernels built
with CONFIG_RCU_CPU_STALL_CPUTIME=y, and restore the full five-minute
timeout limit for expedited RCU CPU stall warnings

workqueue changes for v6.3-rc1
* When per-cpu workqueue workers expire after sitting idle for too long, they used to wake up to the CPU that they're bound to to exit. This unfortunately could cause unwanted disturbances on CPUs isolated for e.g. RT applications.

Updates for the interrupt subsystem:
Core:
- Move the interrupt affinity spreading mechanism into lib/group_cpus
so it can be used for similar spreading requirements, e.g. in the
block multi-queue code.
This also contains a first usecase in the block multi-queue code which
Jens asked to take along with the librarization.
- Improve irqdomain locking to close a number race conditions which
can be observed with massive parallel device driver probing.
- Enforce and document the semantics of disable_irq() which cannot be
invoked safely from non-sleepable context.
- Move the IPI multiplexing code from the Apple AIC driver into the
core. so it can be reused by RISCV.
Drivers:
- Plug OF node refcounting leaks in various drivers.
- Correctly mark level triggered interrupts in the Broadcom L2 drivers.
- The usual small fixes and improvements.
- No new drivers for the record!

Updates for timekeeping, timers and clockevent/source drivers:
Core:
- Yet another round of improvements to make the clocksource watchdog
more robust:
- Relax the clocksource-watchdog skew criteria to match the NTP
criteria.
- Temporarily skip the watchdog when high memory latencies are
detected which can lead to false-positives.
- Provide an option to enable TSC skew detection even on systems
where TSC is marked as reliable.
Sigh!
- Initialize the restart block in the nanosleep syscalls to be directed
to the no restart function instead of doing a partial setup on entry.
This prevents an erroneous restart_syscall() invocation from
corrupting user space data. While such a situation is clearly a user
space bug, preventing this is a correctness issue and caters to the
least suprise principle.
- Ignore the hrtimer slack for realtime tasks in schedule_hrtimeout()
to align it with the nanosleep semantics.
Drivers:
- The obligatory new driver bindings for Mediatek, Rockchip and RISC-V
variants.
- Add support for the C3STOP misfeature to the RISC-V timer to handle
the case where the timer stops in deeper idle state.
- Set up a static key in the RISC-V timer correctly before first use.
- The usual small improvements and fixes all over the place

page_pool: add a comment explaining the fragment counter usage
When reading the page_pool code the first impression is that keeping two separate counters, one being the page refcnt and the other being fragment pp_frag_count, is counter-intuitive. However without that fragment counter we don't know when to reliably destroy or sync the outstanding DMA mappings. So let's add a comment explaining this part.

sefltests: netdevsim: wait for devlink instance after netns removal
When devlink instance is put into network namespace and that network
namespace gets deleted, devlink instance is moved back into init_ns.
This is done as a part of cleanup_net() routine. Since cleanup_net()
is called asynchronously from workqueue, there is no guarantee that
the devlink instance move is done after "ip netns del" returns.
So fix this race by making sure that the devlink instance is present
before any other operation.

selftest: fib_tests: Always cleanup before exit
Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,
leading to a chain of failures.
A simple fix is to always call cleanup function when the script exists.
This approach is already used by other existing tests.
