x86/boot: Address clang -Wimplicit-fallthrough in vsprintf()
After enabling -Wimplicit-fallthrough for the x86 boot code, clang
warns:
arch/x86/boot/printf.c:257:3: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough]
257 | case 'u':
| ^
Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence
the warning.

af_packet: do not call packet_read_pending() from tpacket_destruct_skb()
trafgen performance considerably sank on hosts with many cores after the blamed commit. packet_read_pending() is very expensive, and calling it in af_packet fast path defeats Daniel intent in commit |

idpf: don't skip over ethtool tcp-data-split setting
Disabling tcp-data-split on idpf silently fails:
# ethtool -G $NETDEV tcp-data-split off
# ethtool -g $NETDEV | grep 'TCP data split'
TCP data split: on
But it works if you also change 'tx' or 'rx':
# ethtool -G $NETDEV tcp-data-split off tx 256
# ethtool -g $NETDEV | grep 'TCP data split'
TCP data split: off
The bug is in idpf_set_ringparam, where it takes a shortcut out if the
TX and RX sizes are not changing. Fix it by checking also if the
tcp-data-split setting remains unchanged. Only then can the soft reset
be skipped.

* MTD
Simon Glass wanted to support binman's output properties in order to
check their validity using the binding checks and proposed changes with
the missing properties as well as a binman compatible.
Krzysztof Kozlowski on his side shared a new yaml for describing
Samsung's OneNAND interface.
The interface with NVMEM has also been slightly improved/fixed,
especially now that OTP are also supported in the NAND subsystem.
Along with these changes, small cleanups have also been contributed
around ID tables, structure sizes, arithmetic checks and comments.
* Raw NAND subsystem
Two small fixes, one in the Hynix vendor code for properly returning an
error which might have been ignored and another in the Davinci driver to
properly synchronize the controller with the gpio domain.
* SPI NOR subsystem
SPI NOR now uses div_u64() instead of div64_u64() in places where the
divisor is 32 bits. Many 32 bit architectures can optimize this variant
better than a full 64 bit divide.

rtla: Fix -t\--trace[=file]
The -t option has an optional argument.
The usual case is for a short option to be specified without an '='
and for the long version to be specified with an '='
Various forms of this do not work as expected.
For example:
rtla timerlat hist -T50 -tfile.txt
will result in a truncated file name of "ile.txt"
Another example is that the long form without the '=' will result in the
default file name instead of the requested file name.
This patch properly parses the optional argument with and without '='
and with and without spaces for the short form.
This patch was also tested using -t and --trace without providing a file
name both as the last requested option and with a following long and
short option.
For example:
rtla timerlat hist -T50 -t -u
rtla timerlat hist -T50 --trace -u
This fix is applied to both timerlat top and hist
and to osnoise top and hist.
Here is the full testing for rtla timerlat hist.
Before applying the patch
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 -t file.txt
Default file name instead of file.txt
rtla timerlat hist -T50 --trace=file.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 --trace file.txt
Default file name "timerlat_trace.txt" instead of "file.txt"
After applying the patch:
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -t file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace file.txt
Works as expected, "file.txt"
In addition the following tests were performed to make sure that
the default file name worked as expected including with trailing
options.
rtla timerlat hist -T50 -t
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 -t -u
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace -u
Works as expected "timerlat_trace.txt"

rtla timerlat hit stop tracing
IRQ handler delay: (exit from idle) 48.21 us (91.09 %)
IRQ latency: 49.11 us

Note, the value 18446744073709551615 is the same as ~0.
Fix this by reporting no results for the min, avg and max if the count

rtla: Add --trace-buffer-size option
Add the option allow the users to set a different buffer size for the trace. For example, in large systems, the user might be interested on reducing the trace buffer to avoid large tracing files. The buffer size is specified in kB, and it is only affecting the tracing instance. The function trace_set_buffer_size() appears on libtracefs v1.6, so increase the minimum required version on Makefile.config.

net: qrtr: ns: Fix module refcnt
The qrtr protocol core logic and the qrtr nameservice are combined into
a single module. Neither the core logic or nameservice provide much
functionality by themselves; combining the two into a single module also
prevents any possible issues that may stem from client modules loading
inbetween qrtr and the ns.
Creating a socket takes two references to the module that owns the
socket protocol. Since the ns needs to create the control socket, this
creates a scenario where there are always two references to the qrtr
module. This prevents the execution of 'rmmod' for qrtr.
To resolve this, forcefully put the module refcount for the socket
opened by the nameservice.

Problem statement: During the system boot time, an application request
for the bulk volume of cleared range bias memory when the clear_avail
is zero, we dont fallback into normal allocation method as we had an
unnecessary clear_avail check which prevents the fallback method leads
to fb allocation failure following system goes into unresponsive state.

kprobe/ftrace: bail out if ftrace was killed
If an error happens in ftrace, ftrace_kill() will prevent disarming kprobes. Eventually, the ftrace_ops associated with the kprobes will be freed, yet the kprobes will still be active, and when triggered, they will use the freed memory, likely resulting in a page fault and panic. This behavior can be reproduced quite easily, by creating a kprobe and then triggering a ftrace_kill(). For simplicity, we can simulate an ftrace error with a kernel module like [1]: [1]: https://github.com/brenns10/kernel_stuff/tree/master/ftrace_killer sudo perf probe --add commit_creds sudo perf trace -e probe:commit_creds # In another terminal make sudo insmod ftrace_killer.ko # calls ftrace_kill(), simulating bug # Back to perf terminal # ctrl-c sudo perf probe --del commit_creds After a short period, a page fault and panic would occur as the kprobe continues to execute and uses the freed ftrace_ops. While ftrace_kill() is supposed to be used only in extreme circumstances, it is invoked in FTRACE_WARN_ON() and so there are many places where an unexpected bug could be triggered, yet the system may continue operating, possibly without the administrator noticing. If ftrace_kill() does not panic the system, then we should do everything we can to continue operating, rather than leave a ticking time bomb.

cifs: fix data corruption in read after invalidate
When invalidating a file as part of breaking a lease, the folios holding
the file data are disposed of, and truncate calls ->invalidate_folio()
to get rid of them rather than calling ->release_folio(). This means
that the netfs_inode::zero_point value didn't get updated in current
upstream code to reflect the point after which we can assume that the
server will only return zeroes, and future reads will then return blocks
of zeroes if the file got extended for any region beyond the old zero
point.
Fix this by updating zero_point before invalidating the inode in
cifs_revalidate_mapping().

ARM:
* Move a lot of state that was previously stored on a per vcpu
basis into a per-CPU area, because it is only pertinent to the
host while the vcpu is loaded. This results in better state
tracking, and a smaller vcpu structure.
* Add full handling of the ERET/ERETAA/ERETAB instructions in
nested virtualisation. The last two instructions also require
emulating part of the pointer authentication extension.
As a result, the trap handling of pointer authentication has
been greatly simplified.
* Turn the global (and not very scalable) LPI translation cache
into a per-ITS, scalable cache, making non directly injected
LPIs much cheaper to make visible to the vcpu.
* A batch of pKVM patches, mostly fixes and cleanups, as the
upstreaming process seems to be resuming. Fingers crossed!
* Allocate PPIs and SGIs outside of the vcpu structure, allowing
for smaller EL2 mapping and some flexibility in implementing
more or less than 32 private IRQs.
* Purge stale mpidr_data if a vcpu is created after the MPIDR
map has been created.
* Preserve vcpu-specific ID registers across a vcpu reset.
* Various minor cleanups and improvements.
LoongArch:
* Add ParaVirt IPI support.
* Add software breakpoint support.
* Add mmio trace events support.
RISC-V:
* Support guest breakpoints using ebreak
* Introduce per-VCPU mp_state_lock and reset_cntx_lock
* Virtualize SBI PMU snapshot and counter overflow interrupts
* New selftests for SBI PMU and Guest ebreak
* Some preparatory work for both TDX and SNP page fault handling.
This also cleans up the page fault path, so that the priorities
of various kinds of fauls (private page, no memory, write
to read-only slot, etc.) are easier to follow.
x86:
* Minimize amount of time that shadow PTEs remain in the special
REMOVED_SPTE state. This is a state where the mmu_lock is held for
reading but concurrent accesses to the PTE have to spin; shortening
its use allows other vCPUs to repopulate the zapped region while
the zapper finishes tearing down the old, defunct page tables.
* Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field,
which is defined by hardware but left for software use. This lets KVM
communicate its inability to map GPAs that set bits 51:48 on hosts
without 5-level nested page tables. Guest firmware is expected to
use the information when mapping BARs; this avoids that they end up at
a legal, but unmappable, GPA.
* Fixed a bug where KVM would not reject accesses to MSR that aren't
supposed to exist given the vCPU model and/or KVM configuration.
* As usual, a bunch of code cleanups.
x86 (AMD):
* Implement a new and improved API to initialize SEV and SEV-ES VMs, which
will also be extendable to SEV-SNP. The new API specifies the desired
encryption in KVM_CREATE_VM and then separately initializes the VM.
The new API also allows customizing the desired set of VMSA features;
the features affect the measurement of the VM's initial state, and
therefore enabling them cannot be done tout court by the hypervisor.
While at it, the new API includes two bugfixes that couldn't be
applied to the old one without a flag day in userspace or without
affecting the initial measurement. When a SEV-ES VM is created with
the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are
rejected once the VMSA has been encrypted. Also, the FPU and AVX
state will be synchronized and encrypted too.
* Support for GHCB version 2 as applicable to SEV-ES guests. This, once
more, is only accessible when using the new KVM_SEV_INIT2 flow for
initialization of SEV-ES VMs.
x86 (Intel):
* An initial bunch of prerequisite patches for Intel TDX were merged.
They generally don't do anything interesting. The only somewhat user
visible change is a new debugging mode that checks that KVM's MMU
never triggers a #VE virtualization exception in the guest.
* Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to
L1, as per the SDM.
Generic:
* Use vfree() instead of kvfree() for allocations that always use vcalloc()
or __vcalloc().
* Remove .change_pte() MMU notifier - the changes to non-KVM code are
small and Andrew Morton asked that I also take those through the KVM
tree. The callback was only ever implemented by KVM (which was also the
original user of MMU notifiers) but it had been nonfunctional ever since
calls to set_pte_at_notify were wrapped with invalidate_range_start
and invalidate_range_end... in 2012.
Selftests:
* Enhance the demand paging test to allow for better reporting and stressing
of UFFD performance.
* Convert the steal time test to generate TAP-friendly output.
* Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed
time across two different clock domains.
* Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT.
* Avoid unnecessary use of "sudo" in the NX hugepage test wrapper shell
script, to play nice with running in a minimal userspace environment.
* Allow skipping the RSEQ test's sanity check that the vCPU was able to
complete a reasonable number of KVM_RUNs, as the assert can fail on a
completely valid setup. If the test is run on a large-ish system that is
otherwise idle, and the test isn't affined to a low-ish number of CPUs, the
vCPU task can be repeatedly migrated to CPUs that are in deep sleep states,
which results in the vCPU having very little net runtime before the next
migration due to high wakeup latencies.
* Define _GNU_SOURCE for all selftests to fix a warning that was introduced by
a change to kselftest_harness.h late in the 6.9 cycle, and because forcing
every test to #define _GNU_SOURCE is painful.
* Provide a global pseudo-RNG instance for all tests, so that library code can
generate random, but determinstic numbers.
* Use the global pRNG to randomly force emulation of select writes from guest
code on x86, e.g. to help validate KVM's emulation of locked accesses.
* Allocate and initialize x86's GDT, IDT, TSS, segments, and default exception
handlers at VM creation, instead of forcing tests to manually trigger the
related setup.
Documentation:
* Fix a goof in the KVM_CREATE_GUEST_MEMFD documentation.

Merge tag 'cxl-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dave Jiang:
- Three CXL mailbox passthrough commands are added to support the
populating and clearing of vendor debug logs:
- Get Log Capabilities
- Get Supported Log Sub-List Commands
- Clear Log
- Add support of Device Phyiscal Address (DPA) to Host Physical Address
(HPA) translation for CXL events of cxl_dram and cxl_general media.
This allows user space to figure out which CXL region the event
occured via trace event.
- Connect CXL to CPER reporting.
If a device is configured for firmware first, CXL event records are
not sent directly to the host. Those records are reported through EFI
Common Platform Error Records (CPER). Add support to route the CPER
records through the CXL sub-system in order to provide DPA to HPA
translation and also event decoding and tracing. This is useful for
users to determine which system issues may correspond to specific
hardware events.
- A number of misc cleanups and fixes:
- Fix for compile warning of cxl_security_ops
- Add debug message for invalid interleave granularity
- Enhancement to cxl-test event testing
- Add dev_warn() on unsupported mixed mode decoder
- Fix use of phys_to_target_node() for x86
- Use helper function for decoder enum instead of open coding
