Merge tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull compiler version requirement update from Arnd Bergmann: "Require gcc-8 and binutils-2.30 x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported. With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions. I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible. Since this touches multiple architectures, I merged the patches through the asm-generic tree." * tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: Makefile.kcov: apply needed compiler option unconditionally in CFLAGS_KCOV Documentation: update binutils-2.30 version reference gcc-plugins: remove SANCOV gcc plugin Kbuild: remove structleak gcc plugin arm64: drop binutils version checks raid6: skip avx512 checks kbuild: require gcc-8 and binutils-2.30 |

Merge tag 'trace-ringbuffer-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ring-buffer updates from Steven Rostedt:
- Allow the persistent ring buffer to be memory mapped
In the last merge window there was issues with the implementation of
mapping the persistent ring buffer because it was assumed that the
persistent memory was just physical memory without being part of the
kernel virtual address space. But this was incorrect and the
persistent ring buffer can be mapped the same way as the allocated
ring buffer is mapped.
The metadata for the persistent ring buffer is different than the
normal ring buffer and the organization of mapping it to user space
is a little different. Make the updates needed to the meta data to
allow the persistent ring buffer to be mapped to user space.
- Fix cpus_read_lock() with buffer->mutex and cpu_buffer->mapping_lock
Mapping the ring buffer to user space uses the
cpu_buffer->mapping_lock. The buffer->mutex can be taken when the
mapping_lock is held, giving the locking order of:
cpu_buffer->mapping_lock -->> buffer->mutex. But there also exists
the ordering:
buffer->mutex -->> cpus_read_lock()
mm->mmap_lock -->> cpu_buffer->mapping_lock
cpus_read_lock() -->> mm->mmap_lock
causing a circular chain of:
cpu_buffer->mapping_lock -> buffer->mutex -->> cpus_read_lock() -->>
mm->mmap_lock -->> cpu_buffer->mapping_lock
By moving the cpus_read_lock() outside the buffer->mutex where:
cpus_read_lock() -->> buffer->mutex, breaks the deadlock chain.
- Do not trigger WARN_ON() for commit overrun
When the ring buffer is user space mapped and there's a "commit
overrun" (where an interrupt preempted an event, and then added so
many events it filled the buffer having to drop events when it hit
the preempted event) a WARN_ON() was triggered if this was read via a
memory mapped buffer.
This is due to "missed events" being non zero when the reader page
ended up with the commit page. The idea was, if the writer is on the
reader page, there's only one page that has been written to and there
should be no missed events.
But if a commit overrun is done where the writer is off the commit
page and looped around to the commit page causing missed events, it
is possible that the reader page is the commit page with missed
events.
Instead of triggering a WARN_ON() when the reader page is the commit
page with missed events, trigger it when the reader page is the
tail_page with missed events. That's because the writer is always on
the tail_page if an event was interrupted (which holds the commit
event) and continues off the commit page.
- Reset the persistent buffer if it is fully consumed
On boot up, if the user fully consumes the last boot buffer of the
persistent buffer, if it reboots without enabling it, there will
still be events in the buffer which can cause confusion. Instead,
reset the buffer when it is fully consumed, so that the data is not
read again.
- Clean up some goto out jumps
There's a few cases that the code jumps to the "out:" label that
simply returns a value. There used to be more work done at those
labels but now that they simply return a value use a return instead
of jumping to a label.
- Use guard() to simplify some of the code
Add guard() around some locking instead of jumping to a label to do
the unlocking.
- Use free() to simplify some of the code
Use free(kfree) on variables that will get freed on error and use
return_ptr() to return the variable when its not freed. There's one
instance where free(kfree) simplifies the code on a temp variable
that was allocated just for the function use.

Pull automount updates from Al Viro: "Automount wart removal A bunch of odd boilerplate gone from instances - the reason for those was the need to protect the yet-to-be-attched mount from mark_mounts_for_expiry() deciding to take it out. But that's easy to detect and take care of in mark_mounts_for_expiry() itself; no need to have every instance simulate mount being busy by grabbing an extra reference to it, with finish_automount() undoing that once it attaches that mount. Should've done it that way from the very beginning... This is a flagday change, thankfully there are very few instances. vfs_submount() is gone - its sole remaining user (trace_automount) had been switched to saner primitives" * tag 'pull-automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: kill vfs_submount() saner calling conventions for ->d_automount() |

Pull EFI updates from Ard Biesheuvel:
"Not a lot going on in the EFI tree this cycle. The only thing that
stands out is the new support for SBAT metadata, which was a bit
contentious when it was first proposed, because in the initial
incarnation, it would have required us to maintain a revocation index,
and bump it each time a vulnerability affecting UEFI secure boot got
fixed. This was shot down for obvious reasons.
This time, only the changes needed to emit the SBAT section into the
PE/COFF image are being carried upstream, and it is up to the distros
to decide what to put in there when creating and signing the build.
This only has the EFI zboot bits (which the distros will be using for
arm64); the x86 bzImage changes should be arriving next cycle,
presumably via the -tip tree.
Summary:
- Add support for emitting a .sbat section into the EFI zboot image,
so that downstreams can easily include revocation metadata in the
signed EFI images
- Align PE symbolic constant names with other projects
- Bug fix for the efi_test module
- Log the physical address and size of the EFI memory map when
failing to map it
- A kerneldoc fix for the EFI stub code"

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"This has been a semi-quiet cycle. The core framework remains unchanged
this time around.
In terms of shiny new code though, we have support for the SpacemiT K1
SoC, Sophgo SG2044, and T-HEAD TH1520 VO clk drivers joining the usual
silicon players like Qualcomm, Samsung, Allwinner, and Renesas.
Surprisingly, the Qualcomm pile was smaller than usual but that is
likely because they put one SoC support inside a driver for a
different SoC that is very similar.
Other than all those new clk drivers there are the usual clk data
updates to fix parents, frequency tables, and add missing clks along
with some Kconfig changes to make compile testing simpler and even
more DT binding conversions to boot.
The exciting part is still the new SoC support like SpacemiT and
Sophgo support though, which really dominate the diffstat because they
introduce a whole new silicon vendor clk driver.
New Drivers:
- Camera clock controller driver for Qualcomm QCS8300
- DE (display engine) 3.3 clocks on Allwinner H616
- Samsung ExynosAutov920 CPU cluster CL0, CL1 and CL2 clock controllers
- Video Output (VO) subsystem clk controller in the T-HEAD TH1520 SoC
- Clock driver for Sophgo SG2044
- Clock driver for SpacemiT K1 SoC
- Renesas RZ/V2N (R9A09G056) SoC clk driver
Updates:
- Correct data in various SoC clk drivers
- Allow clkaN to be optional in the Qualcomm RPMh clock controller
driver if command db doesn't define it
- Change Kconfig options to not enable by default during compile
testing
- Add missing clks in various SoC clk drivers
- Remove some duplicate clk DT bindings and convert some more to
YAML"

Merge tag 'trace-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt: - Have module addresses get updated in the persistent ring buffer The addresses of the modules from the previous boot are saved in the persistent ring buffer. If the same modules are loaded and an address is in the old buffer points to an address that was both saved in the persistent ring buffer and is loaded in memory, shift the address to point to the address that is loaded in memory in the trace event. - Print function names for irqs off and preempt off callsites When ignoring the print fmt of a trace event and just printing the fields directly, have the fields for preempt off and irqs off events still show the function name (via kallsyms) instead of just showing the raw address. - Clean ups of the histogram code The histogram functions saved over 800 bytes on the stack to process events as they come in. Instead, create per-cpu buffers that can hold this information and have a separate location for each context level (thread, softirq, IRQ and NMI). Also add some more comments to the code. - Add "common_comm" field for histograms Add "common_comm" that uses the current->comm as a field in an event histogram and acts like any of the other fields of the event. - Show "subops" in the enabled_functions file When the function graph infrastructure is used, a subsystem has a "subops" that it attaches its callback function to. Instead of the enabled_functions just showing a function calling the function that calls the subops functions, also show the subops functions that will get called for that function too. - Add "copy_trace_marker" option to instances There are cases where an instance is created for tooling to write into, but the old tooling has the top level instance hardcoded into the application. New tools want to consume the data from an instance and not the top level buffer. By adding a copy_trace_marker option, whenever the top instance trace_marker is written into, a copy of it is also written into the instance with this option set. This allows new tools to read what old tools are writing into the top buffer. If this option is cleared by the top instance, then what is written into the trace_marker is not written into the top instance. This is a way to redirect the trace_marker writes into another instance. - Have tracepoints created by DECLARE_TRACE() use trace_<name>_tp() If a tracepoint is created by DECLARE_TRACE() instead of TRACE_EVENT(), then it will not be exposed via tracefs. Currently there's no way to differentiate in the kernel the tracepoint functions between those that are exposed via tracefs or not. A calling convention has been made manually to append a "_tp" prefix for events created by DECLARE_TRACE(). Instead of doing this manually, force it so that all DECLARE_TRACE() events have this notation. - Use __string() for task->comm in some sched events Instead of hardcoding the comm to be TASK_COMM_LEN in some of the scheduler events use __string() which makes it dynamic. Note, if these events are parsed by user space it they may break, and the event may have to be converted back to the hardcoded size. - Have function graph "depth" be unsigned to the user Internally to the kernel, the "depth" field of the function graph event is signed due to -1 being used for end of boundary. What actually gets recorded in the event itself is zero or positive. Reflect this to user space by showing "depth" as unsigned int and be consistent across all events. - Allow an arbitrary long CPU string to osnoise_cpus_write() The filtering of which CPUs to write to can exceed 256 bytes. If a machine has 256 CPUs, and the filter is to filter every other CPU, the write would take a string larger than 256 bytes. Instead of using a fixed size buffer on the stack that is 256 bytes, allocate it to handle what is passed in. - Stop having ftrace check the per-cpu data "disabled" flag The "disabled" flag in the data structure passed to most ftrace functions is checked to know if tracing has been disabled or not. This flag was added back in 2008 before the ring buffer had its own way to disable tracing. The "disable" flag is now not always set when needed, and the ring buffer flag should be used in all locations where the disabled is needed. Since the "disable" flag is redundant and incorrect, stop using it. Fix up some locations that use the "disable" flag to use the ring buffer info. - Use a new tracer_tracing_disable/enable() instead of data->disable flag There's a few cases that set the data->disable flag to stop tracing, but this flag is not consistently used. It is also an on/off switch where if a function set it and calls another function that sets it, the called function may incorrectly enable it. Use a new trace_tracing_disable() and tracer_tracing_enable() that uses a counter and can be nested. These use the ring buffer flags which are always checked making the disabling more consistent. - Save the trace clock in the persistent ring buffer Save what clock was used for tracing in the persistent ring buffer and set it back to that clock after a reboot. - Remove unused reference to a per CPU data pointer in mmiotrace functions - Remove unused buffer_page field from trace_array_cpu structure - Remove more strncpy() instances - Other minor clean ups and fixes * tag 'trace-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (36 commits) tracing: Fix compilation warning on arm32 tracing: Record trace_clock and recover when reboot tracing/sched: Use __string() instead of fixed lengths for task->comm tracepoint: Have tracepoints created with DECLARE_TRACE() have _tp suffix tracing: Cleanup upper_empty() in pid_list tracing: Allow the top level trace_marker to write into another instances tracing: Add a helper function to handle the dereference arg in verifier tracing: Remove unnecessary "goto out" that simply returns ret is trigger code tracing: Fix error handling in event_trigger_parse() tracing: Rename event_trigger_alloc() to trigger_data_alloc() tracing: Replace deprecated strncpy() with strscpy() for stack_trace_filter_buf tracing: Remove unused buffer_page field from trace_array_cpu structure tracing: Use atomic_inc_return() for updating "disabled" counter in irqsoff tracer tracing: Convert the per CPU "disabled" counter to local from atomic tracing: branch: Use trace_tracing_is_on_cpu() instead of "disabled" field ring-buffer: Add ring_buffer_record_is_on_cpu() tracing: Do not use per CPU array_buffer.data->disabled for cpumask ftrace: Do not disabled function graph based on "disabled" field tracing: kdb: Use tracer_tracing_on/off() instead of setting per CPU disabled tracing: Use tracer_tracing_disable() instead of "disabled" field for ftrace_dump_one() ... |

summary of what is included in here:
- kernfs locking tweaks, pushing some global locks down into a per-fs

- rust driver core and pci device bindings added for new features.
- sysfs const work for bin_attributes.
The final churn of switching away from and removing the
transitional struct members, "read_new", "write_new" and
"bin_attrs_new" will come after the merge window to avoid
unnecesary merge conflicts.
- auxbus device creation helpers added
- fauxbus fix for creating sysfs files after the probe completed
properly

Pull kvm updates from Paolo Bonzini:
"As far as x86 goes this pull request "only" includes TDX host support.
Quotes are appropriate because (at 6k lines and 100+ commits) it is
much bigger than the rest, which will come later this week and
consists mostly of bugfixes and selftests. s390 changes will also come
in the second batch.
ARM:
- Add large stage-2 mapping (THP) support for non-protected guests
when pKVM is enabled, clawing back some performance.
- Enable nested virtualisation support on systems that support it,
though it is disabled by default.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE
and protected modes.
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. While this has no functional
impact, it ensures correctness of emulation (the data is
automatically extracted from the published JSON files), and helps
dealing with the evolution of the architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
tables in a human-friendly fashion.
- and the usual random cleanups.
LoongArch:
- Don't flush tlb if the host supports hardware page table walks.
- Add KVM selftests support.
RISC-V:
- Add vector registers to get-reg-list selftest
- VCPU reset related improvements
- Remove scounteren initialization from VCPU reset
- Support VCPU reset from userspace using set_mpstate() ioctl
x86:
- Initial support for TDX in KVM.
This finally makes it possible to use the TDX module to run
confidential guests on Intel processors. This is quite a large
series, including support for private page tables (managed by the
TDX module and mirrored in KVM for efficiency), forwarding some
TDVMCALLs to userspace, and handling several special VM exits from
the TDX module.
This has been in the works for literally years and it's not really
possible to describe everything here, so I'll defer to the various
merge commits up to and including commit

ring-buffer: Simplify functions with __free(kfree) to free allocations
The function rb_allocate_pages() allocates cpu_buffer and on error needs to free it. It has a single return. Use __free(kfree) and return directly on errors and have the return use return_ptr(cpu_buffer). The function alloc_buffer() allocates buffer and on error needs to free it. It has a single return. Use __free(kfree) and return directly on errors and have the return use return_ptr(buffer). The function __rb_map_vma() allocates a temporary array "pages". Have it use __free() and not worry about freeing it when returning.

ring-buffer: Simplify ring_buffer_read_page() with guard()
The function ring_buffer_read_page() had two gotos. One was simply returning "ret" and the other was unlocking the reader_lock. There's no reason to use goto to simply return the "ret" variable. Instead just return the value. The jump to the unlocking of the reader_lock can be replaced by guard(raw_spinlock_irqsave)(&cpu_buffer->reader_lock). With these two changes the "ret" variable is no longer used and can be removed. The return value on non-error is what was read and is stored in the "read" variable.
