A set of objtool fixes:
- Handle __ubsan_handle_builtin_unreachable() correctly and treat it as
noreturn.
- Allow architectures to select uaccess validation
- Use the non-instrumented bit test for test_cpu_has() to prevent escape
from non-instrumentable regions.
- Use arch_ prefixed atomics for JUMP_LABEL=n builds to prevent escape
from non-instrumentable regions.
- Mark a few tiny inline as __always_inline to prevent GCC from bringing
them out of line and instrumenting them.
- Mark the empty stub context_tracking_enabled() as always inline as GCC
brings them out of line and instruments the empty shell.
- Annotate ex_handler_msr_mce() as dead end

hte: New subsystem for v5.19-rc1
This contains the new HTE subsystem that has been in the works for a couple of months now. The infrastructure provided allows for drivers to register as hardware timestamp providers, while consumers will be able to request events that they are interested in (such as GPIOs and IRQs) to be timestamped by the hardware providers. Note that this currently supports only one provider, but there seems to be enough interest in this functionality and we expect to see more drivers added once this is merged. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAmKZ77ATHHRyZWRpbmdA bnZpZGlhLmNvbQAKCRDdI6zXfz6zoTgVD/4tdJptbwblr8CCP5jklb81quuKBFu4 2VaUpyGo4TDD4g0jchmAkmB0JsjO7mauURZ/vwWUfDx+uvsOJyf79smY/4OvL0v6 MdYFeXb1rqDX8SiZSnpa+PKNI96l9/l1sbkbj1PPIod8hJSgXsASRP4lF21U97ZY QTI7u3kMJsUEvZhbEs9E2TXPAUO4+M8HfogJuEoaVRyHdwVHY1+Z+jlUsVXRd1qU XpIaKKMWF07FWrs2QUAbdqIUc8cITlcP+ExCc35PMwZnemWHnVwvk0mVyC0XD39P PHGlQOR2zTwJmijCwFkKTwuhGufE6bbvKvdns6gyTUlbzpQ4vcjPfVubt9ehX3dp acEJp5WdJFUhFU4dhjsLGVVzwE/L7vsZ3RPPh1j/Hjt0wYPg/EYPLr/wz+0wbIxt z4AtQZBLwrXSxXUuGkzl139kx0lTEtQZvfiziwi8BWrl6aqeBcGSNYHFLs2rDUTh sap+aEYRQ4cGWYfLMhv3yRLkkTlGxDMmEPM9VWGJb96osBcfidvgT+SE5qwoz6yg yJyMWwCrjYvYl+ZHwfKE3pEE4z9mrs7VLgcW9yWOF4UwFLuH0DyIEtCx/I4Uk+QG 7F1HuV3mYZNlOwgJMZooSJ5Z9uzrn+eGzivhw4klJibFZBXqICCQjL5KvQ8wyuY7 60Ns9+912HV/tQ== =sOJn -----END PGP SIGNATURE----- Merge tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux Pull hardware timestamping subsystem from Thierry Reding: "This contains the new HTE (hardware timestamping engine) subsystem that has been in the works for a couple of months now.

Add partial Loongarch architecture code
This is the majority of the loongarch architecture code, including
the final system call interface and all core functionality.
It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:
- The drivers/firmware/efi stub for booting from a standard UEFI
firmware implementation. Both the original custom boot interface
and a draft implementation of the EFI stub did not make it, so
it is currently impossible to boot the kernel, until the
loongarch specific portions get accepted into the UEFI subsystem
- The drivers/irqchip/irq-loongson-*.c drivers are shared with the
the MIPS port, but currently lack support for ACPI based booting,
which will get merged through the irqchip subsystem.
- Similarly, the drivers/pci/controller/pci-loongson.c needs to be
modified for ACPI support, which will be merged through the
PCI subsystem.
While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI
for the libc ports to build on, and to help any treewide changes
in the mainline kernel get applied here as well. A gcc-12 based
tool chains for build testing is now included in
https://mirrors.edge.kernel.org/pub/tools/crosstool/.
Original description from Huacai Chen at
https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@loongson.cn/:
"LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
boot protocol LoongArch-specific interrupt controllers (similar to APIC)
are already added in the next revision of ACPI Specification (current
revision is 6.4).

This patch enables configuration 'pa_enable' for Arm SPE events, so the physical address packet can be traced, finally this can allow perf c2c tool to locate properly for memory node.

perf record: Support sample-read topdown metric group for hybrid platforms
With the hardware TopDown metrics feature, the sample-read feature should be supported for a TopDown group, e.g., sample a non-topdown event and read a Topdown metric group. But the current perf record code errors are out. For a TopDown metric group,the slots event must be the leader of the group, but the leader slots event doesn't support sampling. To support sample-read the TopDown metric group, uses the 2nd event of the group as the "leader" for the purposes of sampling. Only the platform with the TopDown metric feature supports sample-read the topdown group. In commit |

perf unwind: Fix segbase for ld.lld linked objects
segbase is the address of .eh_frame_hdr and table_data is segbase plus
the header size. find_proc_info computes segbase as `map->start +
segbase - map->pgoff` which is wrong when
* .eh_frame_hdr and .text are in different PT_LOAD program headers
* and their p_vaddr difference does not equal their p_offset difference
Since 10.0, ld.lld's default --rosegment -z noseparate-code layout has
such R and RX PT_LOAD program headers.
ld.lld (default) => perf report fails to unwind `perf record
--call-graph dwarf` recorded data
ld.lld --no-rosegment => ok (trivial, no R PT_LOAD)
ld.lld -z separate-code => ok but by luck: there are two PT_LOAD but
their p_vaddr difference equals p_offset difference
ld.bfd -z noseparate-code => ok (trivial, no R PT_LOAD)
ld.bfd -z separate-code (default for Linux/x86) => ok but by luck:
there are two PT_LOAD but their p_vaddr difference equals p_offset
difference
To fix the issue, compute segbase as dso's base address plus
PT_GNU_EH_FRAME's p_vaddr. The base address is computed by iterating
over all dso-associated maps and then subtract the first PT_LOAD p_vaddr
(the minimum guaranteed by generic ABI) from the minimum address.
In libunwind, find_proc_info transitively called by unw_step is cached,
so the iteration overhead is acceptable.

perf evlist: Extend arch_evsel__must_be_in_group to support hybrid systems
For the hybrid system, the "slots" event changes to "cpu_core/slots/", need
extend API arch_evsel__must_be_in_group() to support hybrid systems.
In the origin code, for hybrid system event "cpu_core/slots/", the output
of the API arch_evsel__must_be_in_group() is "false" (in fact,it should be
"true"). Currently only one API evsel__remove_from_group() calls it. In
evsel__remove_from_group(), it adds the second condition to check, so the
output of evsel__remove_from_group() still is correct. That's the reason
why there isn't an instant error. I'd like to fix the issue found in API
arch_evsel__must_be_in_group() in case someone else using the function in
the other place.

Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1.
Note, I'm not really happy with this pull request as-is, see below for
details, but overall this is all good for everything but a small set of
systems, which we have a fix for already.
Lots of tiny driver core changes and cleanups happened this cycle,
but the two major things were:
- firmware_loader reorganization and additions including the
ability to have XZ compressed firmware images and the ability
for userspace to initiate the firmware load when it needs to,
instead of being always initiated by the kernel. FPGA devices
specifically want this ability to have their firmware changed
over the lifetime of the system boot, and this allows them to
work without having to come up with yet-another-custom-uapi
interface for loading firmware for them.
- physical location support added to sysfs so that devices that
know this information, can tell userspace where they are
located in a common way. Some ACPI devices already support
this today, and more bus types should support this in the
future.
Smaller changes included:
- driver_override api cleanups and fixes
- error path cleanups and fixes
- get_abi script fixes
- deferred probe timeout changes.
It's that last change that I'm the most worried about. It has been
reported to cause boot problems for a number of systems, and I have a
tested patch series that resolves this issue. But I didn't get it
merged into my tree before 5.18-final came out, so it has not gotten any
linux-next testing.
I'll send the fixup patches (there are 2) as a follow-on series to this
pull request if you want to take them directly, _OR_ I can just revert
the probe timeout changes and they can wait for the next -rc1 merge
cycle. Given that the fixes are tested, and pretty simple, I'm leaning
toward that choice. Sorry this all came at the end of the merge window,
I should have resolved this all 2 weeks ago, that's my fault as it was
in the middle of some travel for me.
All have been tested in linux-next for weeks, with no reported issues
other than the above-mentioned boot time outs.

Char / Misc / Other smaller driver subsystem updates for 5.19-rc1
Here is the large set of char, misc, and other driver subsystem updates for 5.19-rc1. The merge request for this has been delayed as I wanted to get lots of linux-next testing due to some late arrivals of changes for the habannalabs driver. Highlights of this merge are: - habanalabs driver updates for new hardware types and fixes and other updates - IIO driver tree merge which includes loads of new IIO drivers and cleanups and additions - PHY driver tree merge with new drivers and small updates to existing ones - interconnect driver tree merge with fixes and updates - soundwire driver tree merge with some small fixes - coresight driver tree merge with small fixes and updates - mhi bus driver tree merge with lots of updates and new device support - firmware driver updates - fpga driver updates - lkdtm driver updates (with a merge conflict, more on that below) - extcon driver tree merge with small updates - lots of other tiny driver updates and fixes and cleanups, full details in the shortlog. All of these have been in linux-next for almost 2 weeks with no reported problems. Note, there are 3 merge conflicts when merging this with your tree: - MAINTAINERS, should be easy to resolve - drivers/slimbus/qcom-ctrl.c, should be straightforward resolution - drivers/misc/lkdtm/stackleak.c, not an easy resolution. This has been noted in the linux-next tree for a while, and resolved there, here's a link to the resolution that Stephen came up with and that Kees says is correct: https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au I will be glad to provide a merge point that contains these resolutions if that makes things any easier for you.

USB / Thunderbolt changes for 5.19-rc1
Here is the "big" set of USB and Thunderbolt driver changes for
5.18-rc1. For the most part it's been a quiet development cycle for the
USB core, but there are the usual "hot spots" of development activity.
Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.
All of these have been in linux-next for weeks with no reported
problems.

bitmap: Fix return values to be unsigned
Both nodemask and bitmap routines had mixed return values that provided potentially signed return values that could never happen. This was leading to the compiler getting confusing about the range of possible return values (it was thinking things could be negative where they could not be). In preparation for fixing nodemask, fix all the bitmap routines that should be returning unsigned (or bool) values.

delayacct: track delays from write-protect copy
Delay accounting does not track the delay of write-protect copy. When
tasks trigger many write-protect copys(include COW and unsharing of
anonymous pages[1]), it may spend a amount of time waiting for them. To
get the delay of tasks in write-protect copy, could help users to evaluate
the impact of using KSM or fork() or GUP.
Also update tools/accounting/getdelays.c:
/ # ./getdelays -dl -p 231

net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_na
RFC 9131 changes default behaviour of handling RX of NA messages when the
corresponding entry is absent in the neighbour cache. The current
implementation is limited to accept just unsolicited NAs. However, the
RFC is more generic where it also accepts solicited NAs. Both types
should result in adding a STALE entry for this case.
Expand accept_untracked_na behaviour to also accept solicited NAs to
be compliant with the RFC and rename the sysctl knob to
accept_untracked_na.

cxl for 5.19
- Add driver-core infrastructure for lockdep validation of
device_lock(), and fixup a deadlock report that was previously hidden
behind the 'lockdep no validate' policy.
- Add CXL _OSC support for claiming native control of CXL hotplug and
error handling.
- Disable suspend in the presence of CXL memory unless and until a
protocol is identified for restoring PCI device context from memory
hosted on CXL PCI devices.
- Add support for snooping CXL mailbox commands to protect against
inopportune changes, like set-partition with the 'immediate' flag set.
- Rework how the driver detects legacy CXL 1.1 configurations (CXL DVSEC
/ 'mem_enable') before enabling new CXL 2.0 decode configurations (CXL
HDM Capability).
- Miscellaneous cleanups and fixes from -next exposure.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for this cycle.
The highlight is new driver-core infrastructure and CXL subsystem
changes for allowing lockdep to validate device_lock() usage. Thanks
to PeterZ for setting me straight on the current capabilities of the
lockdep API, and Greg acked it as well.
On the CXL ACPI side this update adds support for CXL _OSC so that
platform firmware knows that it is safe to still grant Linux native
control of PCIe hotplug and error handling in the presence of CXL
devices. A circular dependency problem was discovered between suspend
and CXL memory for cases where the suspend image might be stored in
CXL memory where that image also contains the PCI register state to
restore to re-enable the device. Disable suspend for now until an
architecture is defined to clarify that conflict.
Lastly a collection of reworks, fixes, and cleanups to the CXL
subsystem where support for snooping mailbox commands and properly
handling the "mem_enable" flow are the highlights.
Summary:
- Add driver-core infrastructure for lockdep validation of
device_lock(), and fixup a deadlock report that was previously
hidden behind the 'lockdep no validate' policy.
- Add CXL _OSC support for claiming native control of CXL hotplug and

selftests: memcg: factor out common parts of memory.{low,min} tests
The memory protection test setup and runtime is almost equal for memory.low and memory.min cases. It makes modification of the common parts prone to mistakes, since the protections are similar not only in setup but also in principle, factor the common part out. Past exceptions between the tests: - missing memory.min is fine (kept), - test_memcg_low protected orphaned pagecache (adapted like test_memcg_min and we keep the processes of protected memory running). The evaluation in two tests is different (OOM of allocator vs low events of protégés), this is kept different.

selftests: memcg: fix compilation
Patch series "memcontrol selftests fixups", v2.
Flushing the patches to make memcontrol selftests check the events
behavior we had consensus about (test_memcg_low fails).
(test_memcg_reclaim, test_memcg_swap_max fail for me now but it's present
even before the refactoring.)
The two bigger changes are:
- adjustment of the protected values to make tests succeed with the given
tolerance,
- both test_memcg_low and test_memcg_min check protection of memory in
populated cgroups (actually as per Documentation/admin-guide/cgroup-v2.rst
memory.min should not apply to empty cgroups, which is not the case
currently. Therefore I unified tests with the populated case in order to to
bring more broken tests).
This patch (of 5):
This fixes mis-applied changes from commit

perf scripts python: Support Arm CoreSight trace data disassembly
This commit adds python script to parse CoreSight tracing event and
print out source line and disassembly, it generates readable program
execution flow for easier humans inspecting.
The script receives CoreSight tracing packet with below format:
+------------+------------+------------+
packet(n): | addr | ip | cpu |
+------------+------------+------------+
packet(n+1): | addr | ip | cpu |
+------------+------------+------------+
packet::addr presents the start address of the coming branch sample, and
packet::ip is the last address of the branch smple. Therefore, a code
section between branches starts from packet(n)::addr and it stops at
packet(n+1)::ip. As results we combines the two continuous packets to
generate the address range for instructions:
[ sample(n)::addr .. sample(n+1)::ip ]
The script supports both objdump or llvm-objdump for disassembly with
specifying option '-d'. If doesn't specify option '-d', the script
simply outputs source lines and symbols.
Below shows usages with llvm-objdump or objdump to output disassembly.

perf scripting python: Expose dso and map information
This change adds dso build_id and corresponding map's start and end address. The info of dso build_id can be used to find dso file path, and we can validate if a branch address falls into the range of map's start and end addresses. In addition, the map's start address can be used as an offset for disassembly.

perf jevents: Fix event syntax error caused by ExtSel
In the origin code, when "ExtSel" is 1, the eventcode will change to
"eventcode |= 1 << 21”. For event “UNC_Q_RxL_CREDITS_CONSUMED_VN0.DRS",
its "ExtSel" is "1", its eventcode will change from 0x1E to 0x20001E,
but in fact the eventcode should <=0x1FF, so this will cause the parse
fail:
# perf stat -e "UNC_Q_RxL_CREDITS_CONSUMED_VN0.DRS" -a sleep 0.1
event syntax error: '.._RxL_CREDITS_CONSUMED_VN0.DRS'
\___ value too big for format, maximum is 511
On the perf kernel side, the kernel assumes the valid bits are continuous.
It will adjust the 0x100 (bit 8 for perf tool) to bit 21 in HW.
DEFINE_UNCORE_FORMAT_ATTR(event_ext, event, "config:0-7,21");
So the perf tool follows the kernel side and just set bit8 other than bit21.

rtla: Remove procps-ng dependency
Daniel Wagner reported to me that readproc.h got deprecated. Also,
while the procps-ng library was available on Fedora, it was not available
on RHEL, which is a piece of evidence that it was not that used.
rtla uses procps-ng only to find the PID of the tracers' workload.
I used the procps-ng library to avoid reinventing the wheel. But in this
case, reinventing the wheel took me less time than the time we already
took trying to work around problems.
Implement a function that reads /proc/ entries, checking if:
- the entry is a directory
- the directory name is composed only of digits (PID)
- the directory contains the comm file
- the comm file contains a comm that matches the tracers'
workload prefix.
- then return true; otherwise, return false.
And use it instead of procps-ng.

rtla/Makefile: Properly handle dependencies
Linus had a problem compiling RTLA, saying:
"[...] I wish the tracing tools would do a bit more package
checking and helpful error messages too, rather than just
fail with:
fatal error: tracefs.h: No such file or directory"
Which is indeed not a helpful message. Update the Makefile, adding
proper checks for the dependencies, with useful information about
how to resolve possible problems.
For example, the previous error is now reported as:
$ make
********************************************
** NOTICE: libtracefs version 1.3 or higher not found
**
** Consider installing the latest libtracefs from your
** distribution, e.g., 'dnf install libtracefs' on Fedora,
** or from source:
**
** https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/
**
********************************************
These messages are inspired by the ones used on trace-cmd, as suggested
by Stevel Rostedt.
Link: https://lore.kernel.org/r/CAHk-=whxmA86E=csNv76DuxX_wYsg8mW15oUs3XTabu2Yc80yw@mail.gmail.com/
Changes from V1:
- Moved the rst2man check to the install phase (when it is used).
- Removed the procps-ng lib check [1] as it is being removed.

asm-generic changes for 5.19
The asm-generic tree contains three separate changes for linux-5.19:
- The h8300 architecture is retired after it has been effectively
unmaintained for a number of years. This is the last architecture we
supported that has no MMU implementation, but there are still a few
architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with
and without an MMU.
- A series to add a generic ticket spinlock that can be shared by most
architectures with a working cmpxchg or ll/sc type atomic, including
the conversion of riscv, csky and openrisc. This series is also a
prerequisite for the loongarch64 architecture port that will come as
a separate pull request.
- A cleanup of some exported uapi header files to ensure they can be
included from user space without relying on other kernel headers.

perf unwind arm64: Decouple Libunwind register names from Perf
DWARF register numbers and real register numbers on aarch64 are equivalent. Remove the references to the register names from Libunwind so that new registers are supported without having to add build time feature checks for each new register. The unwinder won't ask for a register that it doesn't know about and Perf will already report an error for an unknown or unrecorded register in the perf_reg_value() function so extra validation isn't needed. After this change the new VG register can be read by libunwind.

perf unwind: Use dynamic register set for DWARF unwind
Architectures can detect availability of extra registers at runtime so
use this more complete set for unwinding. This will include the VG
register on arm64 in a later commit.
If the function isn't implemented then PERF_REGS_MASK is returned and
there is no change.
Committer notes:
Added util/perf_regs.c to tools/perf/util/python-ext-sources so that
'perf test python' passes, i.e. the perf python binding has all the

perf unwind arm64: Use perf's copy of kernel headers
Fix this include path to use perf's copy of the kernel header rather than the one from the root of the repo. This fixes build errors when only applying the perf tools part of a patchset rather than both sides.

perf c2c: Use stdio interface if slang is not supported
If the slang lib is not installed on the system, perf c2c tool disables TUI
mode and roll back to use stdio mode; but the flag 'c2c.use_stdio' is
missed to set true and thus it wrongly applies UI quirks in the function
ui_quirks().
This commit forces to use stdio interface if slang is not supported, and
it can avoid to apply the UI quirks and show the correct metric header.

perf record: Add cgroup support for off-cpu profiling
This covers two different use cases. The first one is cgroup
filtering given by -G/--cgroup option which controls the off-cpu
profiling for tasks in the given cgroups only.
The other use case is cgroup sampling which is enabled by
--all-cgroups option and it adds PERF_SAMPLE_CGROUP to the sample_type
to set the cgroup id of the task in the sample data.
Example output.
$ sudo perf record -a --off-cpu --all-cgroups sleep 1
$ sudo perf report --stdio -s comm,cgroup --call-graph=no

perf record: Enable off-cpu analysis with BPF
Add --off-cpu option to enable the off-cpu profiling with BPF. It'd
use a bpf_output event and rename it to "offcpu-time". Samples will
be synthesized at the end of the record session using data from a BPF
map which contains the aggregated off-cpu time at context switches.
So it needs root privilege to get the off-cpu profiling.
Each sample will have a separate user stacktrace so it will skip
kernel threads. The sample ip will be set from the stacktrace and
other sample data will be updated accordingly. Currently it only
handles some basic sample types.
The sample timestamp is set to a dummy value just not to bother with
other events during the sorting. So it has a very big initial value
and increase it on processing each samples.
Good thing is that it can be used together with regular profiling like
cpu cycles. If you don't want to that, you can use a dummy event to
enable off-cpu profiling only.
Example output:
$ sudo perf record --off-cpu perf bench sched messaging -l 1000
$ sudo perf report --stdio --call-graph=no
# Total Lost Samples: 0
#
# Samples: 41K of event 'cycles'
# Event count (approx.): 42137343851
...
# Samples: 1K of event 'offcpu-time'
# Event count (approx.): 587990831640

...
As you can see it spent most of off-cpu time in read and write in
bench_sched_messaging(). The --call-graph=no was added just to make
the output concise here.
It uses perf hooks facility to control BPF program during the record
session rather than adding new BPF/off-cpu specific calls.

perf report: Do not extend sample type of bpf-output event
Currently evsel__new_idx() sets more sample_type bits when it finds a BPF-output event. But it should honor what's recorded in the perf data file rather than blindly sets the bits. Otherwise it could lead to a parse error when it recorded with a modified sample_type.

perf test: Add checking for perf stat CSV output.
Counts expected fields for various commands. No testing added for
summary mode since it is broken.
An example of the summary output is:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
,,,,,1.37,stalled cycles per insn
This should be:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
summary,,,,,,1.37,stalled cycles per insn
The output has 7 fields when it should have 8. Additionally, the newline
spacing is wrong, so it was excluded from testing until a fix is made.
Committer testing:
$ perf test "perf stat CSV output"

perf stat: Add requires_cpu flag for uncore
Uncore events require a CPU i.e. it cannot be -1. The evsel system_wide flag is intended for events that should be on every CPU, which does not make sense for uncore events because uncore events do not map one-to-one with CPUs. These 2 requirements are not exactly the same, so introduce a new flag 'requires_cpu' for the uncore case.

To support collection of system-wide events with user requested CPUs, all_cpus must be a superset of user_requested_cpus.

perf auxtrace: Add mmap_needed to auxtrace_mmap_params
Add mmap_needed to auxtrace_mmap_params. Currently an auxtrace mmap is always attempted even if the event is not an auxtrace event. That works because, when AUX area tracing, there is always an auxtrace event first for every mmap.

perf build: Fix btf__load_from_kernel_by_id() feature check
The btf__load_from_kernel_by_id() only takes one arg, not two.
Committer notes:
I tested it just with an older libbpf, one where
btf__load_from_kernel_by_id() wasn't introduced yet.
A test with a newer dynamic libbpf would fail because the
btf__load_from_kernel_by_id() is there, but takes just one arg.
Fixes:

selftests/net: enable lo.accept_local in psock_snd test
The psock_snd test sends and receives packets over loopback, and the test results depend on parameter settings: Set rp_filter=0, or set rp_filter=1 and accept_local=1 so that the test will pass. Otherwise, this test will fail with Resource temporarily unavailable: sudo ./psock_snd.sh dgram tx: 128 rx: 142 ./psock_snd: recv: Resource temporarily unavailable For most distro kernel releases(like Ubuntu or Centos), the parameter rp_filter is enabled by default, so it's necessary to enable the parameter lo.accept_local in psock_snd test. And this test runs inside a netns, changing a sysctl is fine.

sound updates for 5.19-rc1
Not much dramatic changes at this time, but we've received quite
a lot of changes for ASoC, while there are still a few fixes and
quirks for usual HD- and USB-auido. Here are some highlights.
* ASoC:
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs
- Initial stages of Intel AVS driver merge
- Introduction of v4 IPC mechanism for SOF
- TDM mode support for AK4613
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
* Others
- A few regression fixes after the USB-audio endpoint management
refactoring
- More enhancements for Cirrus HD-audio codec support (still ongoing)
- Addition of generic serial MIDI driver

Networking changes for 5.19.
Core
----
- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.
- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).
- Continue work annotating skb drop reasons.
- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.
- Add VLAN support for AF_PACKET SOCK_RAW GSO.
- Allow receiving skb mark from the socket as a cmsg.
- Enable memcg accounting for veth queues, sysctl tables and IPv6.
BPF
---
- Add libbpf support for User Statically-Defined Tracing (USDTs).
- Speed up symbol resolution for kprobes multi-link attachments.
- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.
- Add support for BPF link iterator.
- Introduce access to remote CPU map elements in BPF per-cpu map.
- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.
- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.
Protocols
---------
- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding
to very popular ports (e.g. 443).
- Add bridge FDB bulk flush filtering support allowing user space
to remove all FDB entries matching a condition.
- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.
- Support for MPTCP path manager in user space.
- Add MPTCP support for fallback to regular TCP for connections
that have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).
- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.
- Support lockless operation of GRE tunnels with seq numbers enabled.
- WiFi support for host based BSS color collision detection.
- Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.
- Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).
- Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).
- Allow matching on the number of VLAN tags via tc-flower.
- Add tracepoint for tcp_set_ca_state().
Driver API
----------
- Improve error reporting from classifier and action offload.
- Add support for listing line cards in switches (devlink).
- Add helpers for reporting page pool statistics with ethtool -S.
- Add support for reading clock cycles when using PTP virtual clocks,
instead of having the driver convert to time before reporting.
This makes it possible to report time from different vclocks.
- Support configuring low-latency Tx descriptor push via ethtool.
- Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

linux-kselftest-kunit-5.19-rc1
This KUnit update for Linux 5.19-rc1 consists of several fixes, cleanups,
and enhancements to tests and framework:
- introduces _NULL and _NOT_NULL macros to pointer error checks
- reworks kunit_resource allocation policy to fix memory leaks when
caller doesn't specify free() function to be used when allocating
memory using kunit_add_resource() and kunit_alloc_resource() funcs.
- adds ability to specify suite-level init and exit functions

selftests: vm: add the "settings" file with timeout variable
The default "timeout" for one kselftest is 45 seconds, while some cases in run_vmtests.sh require more time. This will cause testing timeout like: not ok 4 selftests: vm: run_vmtests.sh # TIMEOUT 45 seconds Therefore, add the "settings" file with timeout variable so users can set the "timeout" value.

selftests: vm: check numa_available() before operating "merge_across_nodes" in ksm_tests
Patch series "selftests: vm: a few fixup patches". This series contains three fixup patches for vm selftests. They are independent. Please see the patches. This patch (of 3): Currently, ksm_tests operates "merge_across_nodes" with NUMA either enabled or disabled. In a system with NUMA disabled, these operations will fail and output a misleading report given "merge_across_nodes" does not exist in sysfs: ---------------------------- running ./ksm_tests -M -p 10 ---------------------------- f /sys/kernel/mm/ksm/merge_across_nodes fopen: No such file or directory Cannot save default tunables [FAIL] ---------------------- So check numa_available() before those operations to skip them if NUMA is disabled.

selftests: vm: add process_mrelease tests
Introduce process_mrelease syscall sanity tests which include tests which expect to fail: - process_mrelease with invalid pidfd and flags inputs - process_mrelease on a live process with no pending signals and valid process_mrelease usage which is expected to succeed. Because process_mrelease has to be used against a process with a pending SIGKILL, it's possible that the process exits before process_mrelease gets called. In such cases we retry the test with a victim that allocates twice more memory up to 1GB. This would require the victim process to spend more time during exit and process_mrelease has a better chance of catching the process before it exits and succeeding. On success the test reports the amount of memory the child had to allocate for reaping to succeed. Sample output: $ mrelease_test Success reaping a child with 1MB of memory allocations On failure the test reports the failure. Sample outputs: $ mrelease_test All process_mrelease attempts failed! $ mrelease_test process_mrelease: Invalid argument Link: https://lkml.kernel.org/r/20220518204316.13131-1-surenb@google.com Signed-off-by: Suren Baghdasaryan <surenb@google.com> Reviewed-by: Shuah Khan <skhan@linuxfoundation.org> Acked-by: Christian Brauner (Microsoft) <brauner@kernel.org> Reviewed-by: Muhammad Usama Anjum <usama.anjum@collabora.com> Cc: Michal Hocko <mhocko@suse.com> Cc: David Rientjes <rientjes@google.com> Cc: Matthew Wilcox (Oracle) <willy@infradead.org> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Roman Gushchin <guro@fb.com> Cc: Minchan Kim <minchan@kernel.org> Cc: "Kirill A .

Power management updates for 5.19-rc1
- Update the Energy Model support code to allow the Energy Model to be
artificial, which means that the power values may not be on a uniform
scale with other devices providing power information, and update the
cpufreq_cooling and devfreq_cooling thermal drivers to support
artificial Energy Models (Lukasz Luba).
- Make DTPM check the Energy Model type (Lukasz Luba).

Perf events changes for this cycle were:
Platform PMU changes:
=====================
- x86/intel:
- Add new Intel Alder Lake and Raptor Lake support
- x86/amd:
- AMD Zen4 IBS extensions support
- Add AMD PerfMonV2 support
- Add AMD Fam19h Branch Sampling support
Generic changes:
================
- signal: Deliver SIGTRAP on perf event asynchronously if blocked
Perf instrumentation can be driven via SIGTRAP, but this causes a problem
when SIGTRAP is blocked by a task & terminate the task.
Allow user-space to request these signals asynchronously (after they get
unblocked) & also give the information to the signal handler when this
happens:
" To give user space the ability to clearly distinguish synchronous from
asynchronous signals, introduce siginfo_t::si_perf_flags and
TRAP_PERF_FLAG_ASYNC (opted for flags in case more binary information is
required in future).
The resolution to the problem is then to (a) no longer force the signal
(avoiding the terminations), but (b) tell user space via si_perf_flags
if the signal was synchronous or not, so that such signals can be
handled differently (e.g. let user space decide to ignore or consider
the data imprecise). "
- Unify/standardize the /sys/devices/cpu/events/* output format.
- Misc fixes & cleanups.

Objtool changes for this cycle were:
- Comprehensive interface overhaul:
=================================
Objtool's interface has some issues:
- Several features are done unconditionally, without any way to turn
them off. Some of them might be surprising. This makes objtool
tricky to use, and prevents porting individual features to other
arches.
- The config dependencies are too coarse-grained. Objtool enablement is
tied to CONFIG_STACK_VALIDATION, but it has several other features
independent of that.
- The objtool subcmds ("check" and "orc") are clumsy: "check" is really
a subset of "orc", so it has all the same options. The subcmd model
has never really worked for objtool, as it only has a single purpose:
"do some combination of things on an object file".
- The '--lto' and '--vmlinux' options are nonsensical and have
surprising behavior.
Overhaul the interface:
- get rid of subcmds
- make all features individually selectable
- remove and/or clarify confusing/obsolete options
- update the documentation
- fix some bugs found along the way
- Fix x32 regression
- Fix Kbuild cleanup bugs
- Add scripts/objdump-func helper script to disassemble a single function from an object file.
- Rewrite scripts/faddr2line to be section-aware, by basing it on 'readelf',
moving it away from 'nm', which doesn't handle multiple sections well,
which can result in decoding failure.
- Rewrite & fix symbol handling - which had a number of bugs wrt. object files
that don't have global symbols - which is rare but possible. Also fix a
bunch of symbol handling bugs found along the way.

arm64 updates for 5.19:
- Initial support for the ARMv9 Scalable Matrix Extension (SME). SME takes the approach used for vectors in SVE and extends this to provide architectural support for matrix operations. No KVM support yet, SME is disabled in guests. - Support for crashkernel reservations above ZONE_DMA via the 'crashkernel=X,high' command line option. - btrfs search_ioctl() fix for live-lock with sub-page faults. - arm64 perf updates: support for the Hisilicon "CPA" PMU for monitoring coherent I/O traffic, support for Arm's CMN-650 and CMN-700 interconnect PMUs, minor driver fixes, kerneldoc cleanup. - Kselftest updates for SME, BTI, MTE. - Automatic generation of the system register macros from a 'sysreg' file describing the register bitfields. - Update the type of the function argument holding the ESR_ELx register value to unsigned long to match the architecture register size (originally 32-bit but extended since ARMv8.0). - stacktrace cleanups. - ftrace cleanups. - Miscellaneous updates, most notably: arm64-specific huge_ptep_get(), avoid executable mappings in kexec/hibernate code, drop TLB flushing from get_clear_flush() (and rename it to get_clear_contig()), ARCH_NR_GPIO bumped to 2048 for ARCH_APPLE. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmKH19IACgkQa9axLQDI XvEFWg//bf0p6zjeNaOJmBbyVFsXsVyYiEaLUpFPUs3oB+81s2YZ+9i1rgMrNCft EIDQ9+/HgScKxJxnzWf68heMdcBDbk76VJtLALExbge6owFsjByQDyfb/b3v/bLd ezAcGzc6G5/FlI1IP7ct4Z9MnQry4v5AG8lMNAHjnf6GlBS/tYNAqpmj8HpQfgRQ ZbhfZ8Ayu3TRSLWL39NHVevpmxQm/bGcpP3Q9TtjUqg0r1FQ5sK/LCqOksueIAzT UOgUVYWSFwTpLEqbYitVqgERQp9LiLoK5RmNYCIEydfGM7+qmgoxofSq5e2hQtH2 SZM1XilzsZctRbBbhMit1qDBqMlr/XAy/R5FO0GauETVKTaBhgtj6mZGyeC9nU/+ RGDljaArbrOzRwMtSuXF+Fp6uVo5spyRn1m8UT/k19lUTdrV9z6EX5Fzuc4Mnhed oz4iokbl/n8pDObXKauQspPA46QpxUYhrAs10B/ELc3yyp/Qj3jOfzYHKDNFCUOq HC9mU+YiO9g2TbYgCrrFM6Dah2E8fU6/cR0ZPMeMgWK4tKa+6JMEINYEwak9e7M+ 8lZnvu3ntxiJLN+PrPkiPyG+XBh2sux1UfvNQ+nw4Oi9xaydeX7PCbQVWmzTFmHD q7UPQ8220e2JNCha9pULS8cxDLxiSksce06DQrGXwnHc1Ir7T04= =0DjE -----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: - Initial support for the ARMv9 Scalable Matrix Extension (SME).

bpf: Add dynptr data slices
This patch adds a new helper function void *bpf_dynptr_data(struct bpf_dynptr *ptr, u32 offset, u32 len); which returns a pointer to the underlying data of a dynptr. *len* must be a statically known value. The bpf program may access the returned data slice as a normal buffer (eg can do direct reads and writes), since the verifier associates the length with the returned pointer, and enforces that no out of bounds accesses occur.

bpf: Dynptr support for ring buffers
Currently, our only way of writing dynamically-sized data into a ring buffer is through bpf_ringbuf_output but this incurs an extra memcpy cost. bpf_ringbuf_reserve + bpf_ringbuf_commit avoids this extra memcpy, but it can only safely support reservation sizes that are statically known since the verifier cannot guarantee that the bpf program won’t access memory outside the reserved space. The bpf_dynptr abstraction allows for dynamically-sized ring buffer reservations without the extra memcpy. There are 3 new APIs: long bpf_ringbuf_reserve_dynptr(void *ringbuf, u32 size, u64 flags, struct bpf_dynptr *ptr); void bpf_ringbuf_submit_dynptr(struct bpf_dynptr *ptr, u64 flags); void bpf_ringbuf_discard_dynptr(struct bpf_dynptr *ptr, u64 flags); These closely follow the functionalities of the original ringbuf APIs. For example, all ringbuffer dynptrs that have been reserved must be either submitted or discarded before the program exits.

bpf: Add bpf_dynptr_from_mem for local dynptrs
This patch adds a new api bpf_dynptr_from_mem: long bpf_dynptr_from_mem(void *data, u32 size, u64 flags, struct bpf_dynptr *ptr); which initializes a dynptr to point to a bpf program's local memory.

bpf: Add verifier support for dynptrs
This patch adds the bulk of the verifier work for supporting dynamic
pointers (dynptrs) in bpf.
A bpf_dynptr is opaque to the bpf program. It is a 16-byte structure
defined internally as:
struct bpf_dynptr_kern {
void *data;
u32 size;
u32 offset;
} __aligned(8);
The upper 8 bits of *size* is reserved (it contains extra metadata about
read-only status and dynptr type). Consequently, a dynptr only supports
memory less than 16 MB.
There are different types of dynptrs (eg malloc, ringbuf, ...). In this
patchset, the most basic one, dynptrs to a bpf program's local memory,
is added. For now only local memory that is of reg type PTR_TO_MAP_VALUE
is supported.
In the verifier, dynptr state information will be tracked in stack
slots. When the program passes in an uninitialized dynptr
(ARG_PTR_TO_DYNPTR | MEM_UNINIT), the stack slots corresponding
to the frame pointer where the dynptr resides at are marked
STACK_DYNPTR. For helper functions that take in initialized dynptrs (eg
bpf_dynptr_read + bpf_dynptr_write which are added later in this
patchset), the verifier enforces that the dynptr has been initialized
properly by checking that their corresponding stack slots have been
marked as STACK_DYNPTR.
The 6th patch in this patchset adds test cases that the verifier should
successfully reject, such as for example attempting to use a dynptr
after doing a direct write into it inside the bpf program.

selftests/bpf: fix btf_dump/btf_dump due to recent clang change
Latest llvm-project upstream had a change of behavior
related to qualifiers on function return type ([1]).
This caused selftests btf_dump/btf_dump failure.
The following example shows what changed.
$ cat t.c
typedef const char * const (* const (* const fn_ptr_arr2_t[5])())(char * (*)(int));
struct t {
int a;
fn_ptr_arr2_t l;
};
int foo(struct t *arg) {
return arg->a;
}
Compiled with latest upstream llvm15,
$ clang -O2 -g -target bpf -S -emit-llvm t.c
The related generated debuginfo IR looks like:
!16 = !DIDerivedType(tag: DW_TAG_typedef, name: "fn_ptr_arr2_t", file: !1, line: 1, baseType: !17)
!17 = !DICompositeType(tag: DW_TAG_array_type, baseType: !18, size: 320, elements: !32)
!18 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !19)
!19 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !20, size: 64)
!20 = !DISubroutineType(types: !21)
!21 = !{!22, null}
!22 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !23, size: 64)
!23 = !DISubroutineType(types: !24)
!24 = !{!25, !28}
!25 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !26, size: 64)
!26 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !27)
!27 = !DIBasicType(name: "char", size: 8, encoding: DW_ATE_signed_char)
You can see two intermediate const qualifier to pointer are dropped in debuginfo IR.
With llvm14, we have following debuginfo IR:
!16 = !DIDerivedType(tag: DW_TAG_typedef, name: "fn_ptr_arr2_t", file: !1, line: 1, baseType: !17)
!17 = !DICompositeType(tag: DW_TAG_array_type, baseType: !18, size: 320, elements: !34)
!18 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !19)
!19 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !20, size: 64)
!20 = !DISubroutineType(types: !21)
!21 = !{!22, null}
!22 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !23)
!23 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !24, size: 64)
!24 = !DISubroutineType(types: !25)
!25 = !{!26, !30}
!26 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !27)
!27 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !28, size: 64)
!28 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !29)
!29 = !DIBasicType(name: "char", size: 8, encoding: DW_ATE_signed_char)
All const qualifiers are preserved.
To adapt the selftest to both old and new llvm, this patch removed
the intermediate const qualifier in const-to-ptr types, to make the
test succeed again.

tools/certs: Add print-cert-tbs-hash.sh
Add a new helper print-cert-tbs-hash.sh to generate a TBSCertificate hash from a given certificate. This is useful to generate a blacklist key description used to forbid loading a specific certificate in a keyring, or to invalidate a certificate provided by a PKCS#7 file. This kind of hash formatting is required to populate the file pointed out by CONFIG_SYSTEM_BLACKLIST_HASH_LIST, but only the kernel code was available to understand how to effectively create such hash.
