This add a test to check if the kernel zero-initializes all V registers
after the first-use trap handler returns.
If V registers are not zero-initialized, then the test should fail one
out of several runs:
```
root@sifive-fpga:~# ./v_initval_nolibc
# vl = 256
not ok 1 detect stale values on v-regesters

KVM x86 changes for 6.5:
* Move handling of PAT out of MTRR code and dedup SVM+VMX code
* Fix output of PIC poll command emulation when there's an interrupt
* Add a maintainer's handbook to document KVM x86 processes, preferred coding
style, testing expectations, etc.
* Misc cleanups
- fprobe: Pass return address to the fprobe entry/exit callbacks so that
the callbacks don't need to analyze pt_regs/stack to find the function
return address.
- kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
flags so that those are not set at once.
- fprobe events:
. Add a new fprobe events for tracing arbitrary function entry and
exit as a trace event.
. Add a new tracepoint events for tracing raw tracepoint as a trace
event. This allows user to trace non user-exposed tracepoints.
. Move eprobe's event parser code into probe event common file.
. Introduce BTF (BPF type format) support to kernel probe (kprobe,
fprobe and tracepoint probe) events so that user can specify traced
function arguments by name. This also applies the type of argument
when fetching the argument.
. Introduce '$arg*' wildcard support if BTF is available. This expands
the '$arg*' meta argument to all function argument automatically.
. Check the return value types by BTF. If the function returns 'void',
'$retval' is rejected.
. Add some selftest script for fprobe events, tracepoint events and
BTF support.
. Update documentation about the fprobe events.
. Some fixes for above features, document and selftests.
- selftests for ftrace (except for new fprobe events):
. Add a test case for multiple consecutive probes in a function which
checks if ftrace based kprobe, optimized kprobe and normal kprobe
can be defined in the same target function.
. Add a test case for optimized probe, which checks whether kprobe
can be optimized or not.

- Add new feature to have function graph tracer record the return value.
Adds a new option: funcgraph-retval ; when set, will show the return
value of a function in the function graph tracer.
- Also add the option: funcgraph-retval-hex where if it is not set, and
the return value is an error code, then it will return the decimal of
the error code, otherwise it still reports the hex value.
- Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd
That when a application opens it, it becomes the task that the timer lat
tracer traces. The application can also read this file to find out how
it's being interrupted.
- Add the file /sys/kernel/tracing/available_filter_functions_addrs
that works just the same as available_filter_functions but also shows
the addresses of the functions like kallsyms, except that it gives the
address of where the fentry/mcount jump/nop is. This is used by BPF to
make it easier to attach BPF programs to ftrace hooks.
- Replace strlcpy with strscpy in the tracing boot code.

The user events write currently returns the size of what was suppose to be
written when tracing is disabled and nothing was written. Instead, behave like
trace_marker and return -EBADF, as that is what is returned if a file is opened
for read only, and a write is performed on it. Writing to the buffer
that is disabled is like trying to write to a file opened for read
only, as the buffer still can be read, but just not written to.
This also includes test cases for this use case

Lots of changes as usual, but the only significant stuff in ALSA core
part is the MIDI 2.0 support, while ASoC core kept receiving the code
refactoring. The majority of changes are seen rather in device
drivers, and quite a few new drivers can be found there.
Here we go, some highlights:
ALSA and ASoC Core:
- Support of MIDI 2.0 devices: rawmidi and sequencer API have been
extended for the support of the new UMP (Universal MIDI Packet)
protocol, USB audio driver got the USB MIDI 2.0 interface support
- Continued refactoring around ASoC DAI links and the ordering of
trigger callbacks
- PCM ABI extension for better drain support
ASoC Drivers:
- Conversions of many drivers to use maple tree based caches
- Everlasting improvement works on ASoC Intel drivers
- Compressed audio support for Qualcomm
- Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon,
Ingenic X1000, Intel systems with various CODECs, Loongson
platforms, Maxim MAX98388, Mediatek MT8188, Nuvoton NAU8825C, NXP
platforms with NAU8822, Qualcomm WSA884x, StarFive JH7110, Texas
Instruments TAS2781
HD-audio:
- Quirks for HP and ASUS machines
- CS35L41 HD-audio codec fixes
- Loongson HD-audio support
Misc:
- A new virtual PCM test driver for kselftests
- Continued refactoring and improvements on the legacy emu10k1 driver

Merge tag 'gpio-updates-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have two new drivers, some improvements to the core code, lots of
different updates to existing GPIO drivers and some dt-bindings on
top.
There's nothing controversial in here and almost everything has been
in next for more than a week (95% a lot longer than this). The only
thing that has spent less time in next is a new driver so no risk of
regressions.

numbers from arch/arm/mach-omap.

Core
----
- Rework the sendpage & splice implementations. Instead of feeding
data into sockets page by page extend sendmsg handlers to support
taking a reference on the data, controlled by a new flag called
MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
to invoke an additional callback instead of trying to predict what
the right combination of MORE/NOTLAST flags is.
Remove the MSG_SENDPAGE_NOTLAST flag completely.
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
- Enable socket busy polling with CONFIG_RT.
- Improve reliability and efficiency of reporting for ref_tracker.
- Auto-generate a user space C library for various Netlink families.
Protocols
---------
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2].
- Use per-VMA locking for "page-flipping" TCP receive zerocopy.
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags.
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative.
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
- Avoid waking up applications using TLS sockets until we have
a full record.
- Allow using kernel memory for protocol ioctl callbacks, paving
the way to issuing ioctls over io_uring.
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address.
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch.
- PPPoE: make number of hash bits configurable.
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API
----------
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out).
- Support configuring rate selection pins of SFP modules.
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines.
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer.
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio).
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message.
- Split devlink instance and devlink port operations.

Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.
Core:
- Rework the sendpage & splice implementations
Instead of feeding data into sockets page by page extend sendmsg
handlers to support taking a reference on the data, controlled by a
new flag called MSG_SPLICE_PAGES
Rework the handling of unexpected-end-of-file to invoke an
additional callback instead of trying to predict what the right
combination of MORE/NOTLAST flags is
Remove the MSG_SENDPAGE_NOTLAST flag completely
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid
- Enable socket busy polling with CONFIG_RT
- Improve reliability and efficiency of reporting for ref_tracker
- Auto-generate a user space C library for various Netlink families
Protocols:
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2]
- Use per-VMA locking for "page-flipping" TCP receive zerocopy
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative
- Create a new MPTCP getsockopt to retrieve all info
(MPTCP_FULL_INFO)
- Avoid waking up applications using TLS sockets until we have a full
record
- Allow using kernel memory for protocol ioctl callbacks, paving the
way to issuing ioctls over io_uring
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch
- PPPoE: make number of hash bits configurable
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig)
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge)
- Support matching on Connectivity Fault Management (CFM) packets
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug
- HSR: don't enable promiscuous mode if device offloads the proto
- Support active scanning in IEEE 802.15.4
- Continue work on Multi-Link Operation for WiFi 7
BPF:
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used, or
in fact passing the verifier at all for complex programs,
especially those using open-coded iterators
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what the
output buffer *should* be, without writing anything
- Accept dynptr memory as memory arguments passed to helpers
- Add routing table ID to bpf_fib_lookup BPF helper
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only)
- Show target_{obj,btf}_id in tracing link fdinfo
- Addition of several new kfuncs (most of the names are
self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter:
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value
- Increase ip_vs_conn_tab_bits range for 64BIT builds
- Allow updating size of a set
- Improve NAT tuple selection when connection is closing
Driver API:
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out)
- Support configuring rate selection pins of SFP modules
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio)
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message
- Split devlink instance and devlink port operations

The changes queued up for v6.5-rc1 for sysctl are in line with
prior efforts to stop usage of deprecated routines which incur
recursion and also make it hard to remove the empty array element
in each sysctl array declaration. The most difficult user to modify
was parport which required a bit of re-thinking of how to declare shared
sysctls there, Joel Granados has stepped up to the plate to do most of
this work and eventual removal of register_sysctl_table(). That work
ended up saving us about 1465 bytes according to bloat-o-meter. Since
we gained a few bloat-o-meter karma points I moved two rather small
sysctl arrays from kernel/sysctl.c leaving us only two more sysctl
arrays to move left.
Most changes have been tested on linux-next for about a month. The last
straggler patches are a minor parport fix, changes to the sysctl
kernel selftest so to verify correctness and prevent regressions for
the future change he made to provide an alternative solution for the
special sysctl mount point target which was using the now deprecated
sysctl child element.
This is all prep work to now finally be able to remove the empty
array element in all sysctl declarations / registrations which is
expected to save us a bit of bytes all over the kernel. That work
will be tested early after v6.5-rc1 is out.

The changes queued up for v6.5-rc1 for modules are pretty tame, mostly
code removal of moving of code. Only two minor functional changes are
made, the only one which stands out is Sebastian Andrzej Siewior's
simplification of module reference counting by removing preempt_disable()
and that has been tested on linux-next for well over a month without
no regressions. I'm now, I guess, also a kitchen sink for some kallsyms
changes.

Pull hardening updates from Kees Cook:
"There are three areas of note:
A bunch of strlcpy()->strscpy() conversions ended up living in my tree
since they were either Acked by maintainers for me to carry, or got
ignored for multiple weeks (and were trivial changes).
The compiler option '-fstrict-flex-arrays=3' has been enabled
globally, and has been in -next for the entire devel cycle. This
changes compiler diagnostics (though mainly just -Warray-bounds which
is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
coverage. In other words, there are no new restrictions, just
potentially new warnings. Any new FORTIFY warnings we've seen have
been fixed (usually in their respective subsystem trees). For more
details, see commit df8fc4e934.
The under-development compiler attribute __counted_by has been added
so that we can start annotating flexible array members with their
associated structure member that tracks the count of flexible array
elements at run-time. It is possible (likely?) that the exact syntax
of the attribute will change before it is finalized, but GCC and Clang
are working together to sort it out. Any changes can be made to the
macro while we continue to add annotations.
As an example of that last case, I have a treewide commit waiting with
such annotations found via Coccinelle:
https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b
Also see commit dd06e72e68 for more details.
Summary:
- Fix KMSAN vs FORTIFY in strlcpy/strlcat (Alexander Potapenko)
- Convert strreplace() to return string start (Andy Shevchenko)
- Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook)
- Add missing function prototypes seen with W=1 (Arnd Bergmann)
- Fix strscpy() kerndoc typo (Arne Welzel)
- Replace strlcpy() with strscpy() across many subsystems which were
either Acked by respective maintainers or were trivial changes that
went ignored for multiple weeks (Azeem Shaikh)
- Remove unneeded cc-option test for UBSAN_TRAP (Nick Desaulniers)
- Add KUnit tests for strcat()-family
- Enable KUnit tests of FORTIFY wrappers under UML
- Add more complete FORTIFY protections for strlcat()
- Add missed disabling of FORTIFY for all arch purgatories.
- Enable -fstrict-flex-arrays=3 globally
- Tightening UBSAN_BOUNDS when using GCC
- Improve checkpatch to check for strcpy, strncpy, and fake flex
arrays
- Improve use of const variables in FORTIFY
- Add requested struct_size_t() helper for types not pointers
- Add __counted_by macro for annotating flexible array size members"

Pull landlock updates from Mickaël Salaün:
"Add support for Landlock to UML.
To do this, this fixes the way hostfs manages inodes according to the
underlying filesystem [1]. They are now properly handled as for other
filesystems, which enables Landlock support (and probably other
features).
This also extends Landlock's tests with 6 pseudo filesystems,
including hostfs"

very big one from the point of view of new drivers:
- More refectoring from Morimoto-san, this time mainly around DAI
links and how we control the ordering of trigger() callbacks.

Pick up the first half of the RCH error handling series. The back half
needs some fixups for test regressions. Small conflicts with the PMU
work around register enumeration and setup helpers.
Pick up initial support for the CXL 3.0 performance monitoring
definition. Small conflicts with the firmware update work as they both
placed their init code in the same location.
Pick up the driver cleanups identified in preparation for CXL "type-2"
(accelerator) device support. The major change here from a conflict
generation perspective is the split of 'struct cxl_memdev_state' from
the core 'struct cxl_dev_state'. Since an accelerator may not care about
all the optional features that are standard on a CXL "type-3" (host-only
memory expander) device.
A silent conflict also occurs with the move of the endpoint port to be a
formal property of a 'struct cxl_memdev' rather than drvdata.
Add the first typical (non-sanitization) consumer of the new background
command infrastructure, firmware update. Given both firmware-update and
sanitization were developed in parallel from the common
background-command baseline, resolve some minor context conflicts.
Pick up the sanitization work and the infrastructure for other
background commands for 6.5. Sanitization has a different completion
path than typical background commands so it was important to have both
thought out and implemented before either went upstream.
Add emulation for the 'Get FW Info', 'Transfer FW', and 'Activate FW'
CXL mailbox commands to the cxl_test emulated memdevs to enable
end-to-end unit testing of a firmware update flow. For now, only
advertise an 'offline activation' capability as that is all the CXL
memdev driver currently implements.
Add some canned values for the serial number fields, and create a
platform device sysfs knob to calculate the sha256sum of the firmware
image that was received, so a unit test can compare it with the original
file that was uploaded.

commit eb0764b822 ("cxl/port: Enable the HDM decoder capability for switch ports")
...was added on the observation of CXL memory not being accessible after
setting up a region on a "cold-plugged" device. A "cold-plugged" CXL
device is one that was not present at boot, so platform-firmware/BIOS
has no chance to set it up.
While it is true that the debug found the enable bit clear in the
host-bridge's instance of the global control register (CXL 3.0
8.2.4.19.2 CXL HDM Decoder Global Control Register), that bit is
described as:
"This bit is only applicable to CXL.mem devices and shall
return 0 on CXL Host Bridges and Upstream Switch Ports."
So it is meant to be zero, and further testing confirmed that this "fix"
had no effect on the failure. Revert it, and be more vigilant about
proposed fixes in the future. Since the original copied stable@, flag
this revert for stable@ as well.

'struct cxl_dev_state' makes too many assumptions about the capabilities
of a CXL device. In particular it assumes a CXL device has a mailbox and
all of the infrastructure and state that comes along with that.
In preparation for supporting accelerator / Type-2 devices that may not
have a mailbox and in general maintain a minimal core context structure,
make mailbox functionality a super-set of 'struct cxl_dev_state' with
'struct cxl_memdev_state'.
With this reorganization it allows for CXL devices that support HDM
decoder mapping, but not other general-expander / Type-3 capabilities,
to only enable that subset without the rest of the mailbox
infrastructure coming along for the ride.

Prepare cxl_probe_rcrb() for retrieving more than just the component
register block. The RCH AER handling code wants to get back to the AER
capability that happens to be MMIO mapped rather then configuration
cycles.
Move RCRB specific downstream port data, like the RCRB base and the
AER capability offset, into its own data structure ('struct
cxl_rcrb_info') for cxl_probe_rcrb() to fill. Extend 'struct
cxl_dport' to include a 'struct cxl_rcrb_info' attribute.
This centralizes all RCRB scanning in one routine.

The RCRB is extracted already during ACPI CEDT table parsing while the
data of this is needed not earlier than dport creation. This
implementation comes with drawbacks: During ACPI table scan there is
already MMIO access including mapping and unmapping, but only ACPI
data should be collected here. The collected data must be transferred
through a couple of interfaces until it is finally consumed when
creating the dport. This causes complex data structures and function
interfaces. Additionally, RCRB parsing will be extended to also
extract AER data, it would be much easier do this at a later point
during port and dport creation when the data structures are available
to hold that data.
To simplify all that, probe the RCRB at a later point during RCH
downstream port creation. Change ACPI table parser to only extract the
base address of either the component registers or the RCRB. Parse and
extract the RCRB in devm_cxl_add_rch_dport().
This is in preparation to centralize all RCRB scanning.

Before server got a client connection, there were some memory allocations
in the test memcg, such as user stack. So do not count those allocations
which are not related to socket when checking socket memory accounting.

making sure that the original value is restored after returning from the

Basically, with header files in my local host which is based on 5.12 kernel,
__always_inline is not defined and this caused compilation failure.
Since __always_inline is defined in bpf_helpers.h, let us move bpf_helpers.h
to an early position which fixed the problem.

When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.
If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.
Fix this by setting the neighbor's state to permanent in a couple of
tests, so that it is always valid.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the MPTCP MIB counters introduced in commit fc518953bc
("mptcp: add and use MIB counter infrastructure") and more later. The
MPTCP Join selftest heavily relies on these counters.
If a counter is not supported by the kernel, it is not displayed when
using 'nstat -z'. We can then detect that and skip the verification. A
new helper (get_counter()) has been added recently in the -net tree to
do the required checks and return an error if the counter is not
available.
This commit is similar to the one with the same title applied in the
-net tree but it modifies code only present in net-next for the moment,
see the Fixes commit below.
While at it, we can also remove the use of ${extra_msg} variable which
is never assigned in chk_rm_tx_nr() function and use 'echo' without '-n'
parameter.

In a future patch, mlxsw will start adding RIFs to uppers of front panel
port netdevices, if they have an IP address.
At the time that the front panel port is enslaved to the bridge, the bridge
MAC address does not have the same prefix as other interfaces in the
system. On Nvidia Spectrum-1 machines all the RIFs have to have the same
38-bit MAC address prefix. Since the bridge does not obey this limitation,
the RIF cannot be created, and the enslavement attempt is vetoed on the
grounds of the configuration not being offloadable.
The bridge eventually inherits MAC address from its first member, after the
enslavement is acked. A number of (mainly VXLAN) selftests already work
around the problem by setting the MAC address to whatever it will
eventually be anyway. Do the same for this selftest.

. Add persistent logic (but not let user space use it yet)

get cleaned up automatically) is useful. But there's still
debates about how to expose this to user space. The infrastructure

uffd_register()
uffd_unregister()
uffd_register_with_ioctls().

MADV_PAGEOUT, MADV_POPULATE_READ, MADV_COLLAPSE are conditionally
defined as necessary. However, that was being done in .c files, and a
new build failure came up that would have been automatically avoided had
these been in a common header file.
So consolidate and move them all to vm_util.h, which fixes the build
failure.
An alternative approach from Muhammad Usama Anjum was: rely on "make
headers" being required, and include asm-generic/mman-common.h. This
works in the sense that it builds, but it still generates warnings about
duplicate MADV_* symbols, and the goal here is to get a fully clean (no
warnings) build here.

The uffd tests generate two compile time warnings from clang's
-Wformat-security setting. These trigger at the call sites for
uffd_test_start() and uffd_test_skip().
1) Fix the uffd_test_start() issue by removing the intermediate
test_name variable (thanks to David Hildenbrand for showing how to do
this).
2) Fix the uffd_test_skip() issue by observing that there is no need for
a macro and a variable args approach, because all callers of
uffd_test_skip() pass in a simple char* string, without any format
specifiers. So just change uffd_test_skip() into a regular C function.

We cannot depend upon git to reliably retain the executable bit on shell
scripts, or so I was told several years ago while working on this same
run_vmtests.sh script. And sure enough, things such as test_hmm.sh are
lately failing to run, due to lacking execute permissions.
Fix this by explicitly adding "bash" to each of the shell script
invocations. Leave fixing the overall approach to another day.

The stop variable is a char*, and the code was assigning a char value to
it. This was generating a warning when compiling with clang.
However, as both David and Peter pointed out, stop is not even used
after the problematic assignment to a char type. So just delete that
line entirely.

Dummy variables are required in order to make these two (similar)
routines work, so in both cases, declare the variables as volatile in
order to avoid the clang compiler warning.
Furthermore, in order to ensure that each test actually does what is
intended, add an asm volatile invocation (thanks to David Hildenbrand
for the suggestion), with a clarifying comment so that it survives
future maintenance.

Patch series "A minor flurry of selftest/mm fixes", v3.
A series that fixes up build errors and warnings for at least the 64-bit
builds on x86 with clang.
The series also includes an optional "improvement" of moving some uffd
code into uffd-common.[ch], which is proving to be somewhat controversial,
and so if that doesn't get resolved, then patches 9 and 10 may just get
dropped. They are not required in order to get a clean build, now that
"make headers" is happening.

Currently the MM selftests attempt to work out the target architecture by
using CROSS_COMPILE or otherwise querying the host machine, storing the
target architecture in a variable called MACHINE rather than the usual
ARCH though as far as I can tell (including for x86_64) the value is the
same as we would use for architecture.
When cross compiling with LLVM we don't need a CROSS_COMPILE as LLVM can
support many target architectures in a single build so this logic does not
work, CROSS_COMPILE is not set and we end up selecting tests for the host
rather than target architecture. Fix this by using the more standard ARCH
to describe the architecture, taking it from the environment if specified.

Add a selftest for CMMA migration on s390.
The tests cover:
- interaction of dirty tracking and migration mode, see my recent patch
"KVM: s390: disable migration mode when dirty tracking is disabled" [1],
- several invalid calls of KVM_S390_GET_CMMA_BITS, for example: invalid
flags, CMMA support off, with/without peeking
- ensure KVM_S390_GET_CMMA_BITS initally reports all pages as dirty,
- ensure KVM_S390_GET_CMMA_BITS properly skips over holes in memslots, but
also non-dirty pages
Note that without the patch at [1] and the small fix in this series, the
selftests will fail.

Previously, timestamps were printed using "%lld.%u" which is incorrect
for nanosecond values lower than 100,000,000 as they're fractional

User processes register name_args for events. If the same name but different
args event are registered. The trace outputs of second event are printed
as the first event. This is incorrect.
Return EADDRINUSE back to the user process if the same name but different args
event has being registered.

Setting the IPv6 address generation mode of a net device during its
creation never worked, but after commit b0ad3c1790 ("rtnetlink: call
validate_linkmsg in rtnl_create_link") it explicitly fails [1]. The
failure is caused by the fact that validate_linkmsg() is called before
the net device is registered, when it still does not have an 'inet6_dev'.
Likewise, raising the net device before setting the address generation
mode is meaningless, because by the time the mode is set, the address
has already been generated.
Therefore, fix the test to first create the net device, then set its
IPv6 address generation mode and finally bring it up.

Some qdiscs and classifiers have recently been retired from kernel.
However, tc-testing config is still cluttered with them which causes noise
when using merge_config.sh script to update existing config for tc-testing
compatibility. Remove the config settings for affected qdiscs and

Setting very small value of db like 10ms introduces rounding errors when
converting to/from jiffies on some kernel configs. For example, on 250hz
the actual value will be set to 12ms which causes the test to fail:
# $ sudo ./tdc.py -d eth2 -e 3410
# -- ns/SubPlugin.__init__
# Test 3410: Create SFB with db setting
#
# All test results:
#
# 1..1
# not ok 1 3410 - Create SFB with db setting
# Could not match regex pattern. Verify command output:

Set the value to 100ms instead which currently seem to work on 100hz,
250hz, 300hz and 1000hz kernel configs.

Verify that the following example is rejected by verifier:
r9 = ... some pointer with range X ...
r6 = ... unbound scalar ID=a ...
r7 = ... unbound scalar ID=b ...
if (r6 > r7) goto +1
r7 = r6
if (r7 > X) goto exit
r9 += r6
*(u64 *)r9 = Y
Also add test cases to:
- check that check_alu_op() for BPF_MOV instruction does not allocate
scalar ID if source register is a constant;
- check that unique scalar IDs are ignored when new verifier state is
compared to cached verifier state;
- check that two different scalar IDs in a verified state can't be
mapped to the same scalar ID in current state.

Check __mark_chain_precision() log to verify that scalars with same
IDs are marked as precise. Use several scenarios to test that
precision marks are propagated through:
- registers of scalar type with the same ID within one state;
- registers of scalar type with the same ID cross several states;
- registers of scalar type with the same ID cross several stack frames;
- stack slot of scalar type with the same ID;
- multiple scalar IDs are tracked independently.

Change mark_chain_precision() to track precision in situations
like below:
r2 = unknown value
...
--- state #0 ---
...
r1 = r2 // r1 and r2 now share the same ID
...
--- state #1 {r1.id = A, r2.id = A} ---
...
if (r2 > 10) goto exit; // find_equal_scalars() assigns range to r1
...
--- state #2 {r1.id = A, r2.id = A} ---
r3 = r10
r3 += r1 // need to mark both r1 and r2
At the beginning of the processing of each state, ensure that if a
register with a scalar ID is marked as precise, all registers sharing
this ID are also marked as precise.
This property would be used by a follow-up change in regsafe().

Add "-MD" in CFLAGS to generate dependency files. Currently, each
time a header file is updated in KVM selftest, we will have to run
"make clean && make" to rebuild the whole test suite. By adding new
compiling flags and dependent rules in Makefile, we do not need to
make clean && make each time a header file is updated.
