Pull bcachefs updates from Kent Overstreet:
- More safety fixes, primarily found by syzbot
- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata
in memory.
The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.
- btree_trans->locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for
improving how we work with lockdep in the future: we don't want
lockdep to be tracking individual btree node locks because we take
too many for lockdep to track, and it's not necessary since we have a
cycle detector.
- Trigger improvements that are prep work for online fsck
- BTREE_TRIGGER_check_repair; this regularizes how we do some repair
work for extents that goes with running triggers in fsck, and fixes
some subtle issues with transaction restarts there.
- bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot
equivalence classes are for when snapshot deletion leaves behind
redundant snapshot nodes, but snapshot deletion now cleans this up
right away, so the abstraction doesn't need to leak.
- Improvements to how we resume writing to the journal in recovery. The
code for picking the new place to write when reading the journal is
greatly simplified and we also store the position in the superblock
for when we don't read the journal; this means that we preserve more
of the journal for list_journal debugging.
- Improvements to sysfs btree_cache and btree_node_cache, for debugging
memory reclaim.
- We now detect when we've blocked for 10 seconds on the allocator in
the write path and dump some useful info.
- Safety fixes for devices references: this is a big series that
changes almost all device lookups to properly check if the device
exists and take a reference to it.
Previously we assumed that if a bkey exists that references a device
then the device must exist, and this was enforced in .invalid
methods, but this was incorrect because it meant device removal
relied on accounting being correct to not leave keys pointing to
invalid devices, and that's not something we can assume.
Getting the "pointer to invalid device" checks out of our .invalid()
methods fixes some long standing device removal bugs; the only
outstanding bug with device removal now is a race between the discard
path and deleting alloc info, which should be easily fixed.
- The allocator now prefers not to expand the new
member_info.btree_allocated bitmap, meaning if repair ever requires
scanning for btree nodes (because of a corrupt interior nodes) we
won't have to scan the whole device(s).
- New coding style document, which among other things talks about the
correct usage of assertions

If modules are built compressed, and LoadPin is enforcing by default, we
must have in-kernel module decompression enabled (MODULE_DECOMPRESS).
Modules will fail to load without decompression built into the kernel
because they'll be blocked by LoadPin. Add a depends on clause to
prevent this combination.

"Aside from the usual things this has an arch update for

Pull clk updates from Stephen Boyd:
"I'm actually surprised this time. There aren't any new Qualcomm SoC
clk drivers. And there's zero diff in the core clk framework.
Instead we have new clk drivers for STM and Sophgo, with
Samsung^WGoogle in third for the diffstat because they introduced HSI0
and HSI2 clk drivers for Google's GS101 SoC (high speed interface
things like PCIe, UFS, and MMC).
Beyond those big diffs there's the usual updates to various clk
drivers for incorrect parent descriptions or mising
MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
interesting here.
New Drivers:
- STM32MP257 SoC clk driver
- Airoha EN7581 SoC clk driver
- Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
- Loongson-2k0500 and Loongson-2k2000 SoC clk driver

Commit 1a7d0890dd4a ("kprobe/ftrace: bail out if ftrace was killed")
introduced a bad K&R function definition, which we haven't accepted in a
long long time.
Gcc seems to let it slide, but clang notices with the appropriate error:
kernel/kprobes.c:1140:24: error: a function declaration without a prototype is deprecated in all >
1140 | void kprobe_ftrace_kill()
| ^
| void
but this commit was apparently never in linux-next before it was sent
upstream, so it didn't get the appropriate build test coverage.

Pull tracing tool updates from Steven Rostedt:
"Specific for timerlat:
- Improve the output of timerlat top by adding a missing \n, and by
avoiding printing color-formatting characters where they are
translated to regular characters.
- Improve timerlat auto-analysis output by replacing '\t' with spaces
to avoid copy-and-paste issues when reporting problems.
- Make the user-space (-u) option the default, as it is the most
complete test. Add a -k option to use the in-kernel workload.
- On timerlat top and hist, add a summary with the overall results.
For instance, the minimum value for all CPUs, the overall average
and the maximum value from all CPUs.
- timerlat hist was printing initial values (i.e., 0 as max, and ~0
as min) if the trace stopped before the first Ret-User event. This
problem was fixed by printing the " - " no value string to the
output if that was the case.
For all RTLA tools:
- Add a --warm-up <seconds> option, allowing the workload to run for
<seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set the
tracing buffer size for -t option. This option is mainly useful for
reducing the trace file. Now rtla depends on libtracefs >= 1.6.
- Fix the -t [trace_file] parsing, now it does not require the '='
before the option parameter, and better handles the multiple ways a
user can pass the trace_file.txt"

Pull tracing user-event updates from Steven Rostedt:
- Minor update to the user_events interface
The ABI of creating a user event states that the fields are separated
by semicolons, and spaces should be ignored.
But the parsing expected at least one space to be there (which was
incorrect). Fix the reading of the string to handle fields separated
by semicolons but no space between them.
This does extend the API sightly as now "field;field" will now be
parsed and not cause an error. But it should not cause any regressions
as no logic should expect it to fail.
Note, that the logic that parses the event fields to create the
trace_event works with no spaces after the semi-colon. It is
the logic that tests against existing events that is inconsistent.
This causes registering an event without using spaces to succeed
if it doesn't exist, but makes the same call that tries to register
to the same event, but doesn't use spaces, fail.

Pull tracing ring buffer updates from Steven Rostedt:
"Add ring_buffer memory mappings.
The tracing ring buffer was created based on being mostly used with
the splice system call. It is broken up into page ordered sub-buffers
and the reader swaps a new sub-buffer with an existing sub-buffer
that's part of the write buffer. It then has total access to the
swapped out sub-buffer and can do copyless movements of the memory
into other mediums (file system, network, etc).
The buffer is great for passing around the ring buffer contents in the
kernel, but is not so good for when the consumer is the user space
task itself.
A new interface is added that allows user space to memory map the ring
buffer. It will get all the write sub-buffers as well as reader
sub-buffer (that is not written to). It can send an ioctl to change
which sub-buffer is the new reader sub-buffer.
The ring buffer is read only to user space. It only needs to call the
ioctl when it is finished with a sub-buffer and needs a new sub-buffer
that the writer will not write over.
A self test program was also created for testing and can be used as an
example for the interface to user space. The libtracefs (external to
the kernel) also has code that interacts with this, although it is
disabled until the interface is in a official release. It can be
enabled by compiling the library with a special flag. This was used
for testing applications that perform better with the buffer being
mapped.
Memory mapped buffers have limitations. The main one is that it can
not be used with the snapshot logic. If the buffer is mapped,
snapshots will be disabled. If any logic is set to trigger snapshots
on a buffer, that buffer will not be allowed to be mapped"

Removing sentinels in ctl_table arrays reduces the build time size
and runtime memory consumed by ~64 bytes per array. Removals for
net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline
through their respective subsystems making the next release the most
likely place where the final series that removes the check for
proc_name == NULL will land.
This adds to removals already in arch/, drivers/ and fs/.
- Adjust ctl_table definitions and references to allow constification
- Remove unused ctl_table function arguments
- Move non-const elements from ctl_table to ctl_table_header
- Make ctl_table pointers const in ctl_table_root structure
Making the static ctl_table structs const will increase safety by
keeping the pointers to proc_handler functions in .rodata. Though no
ctl_tables where made const in this PR, the ground work for making
that possible has started with these changes sent by Thomas
Weißschuh.

Since commit a36e185e8c85
("udp: Handle ICMP errors for tunnels with same destination port on both endpoints")
UDP's handling of ICMP errors has allowed for UDP-encap tunnels to
determine socket associations in scenarios where the UDP hash lookup
could not.
Subsequently, commit d26796ae58940
("udp: check udp sock encap_type in __udp_lib_err")
subtly tweaked the approach such that UDP ICMP error handling would be
skipped for any UDP socket which has encapsulation enabled.
In the case of L2TP tunnel sockets using UDP-encap, this latter
modification effectively broke ICMP error reporting for the L2TP
control plane.
To a degree this isn't catastrophic inasmuch as the L2TP control
protocol defines a reliable transport on top of the underlying packet
switching network which will eventually detect errors and time out.
However, paying attention to the ICMP error reporting allows for more
timely detection of errors in L2TP userspace, and aids in debugging
connectivity issues.
Reinstate ICMP error handling for UDP encap L2TP tunnels:
* implement struct udp_tunnel_sock_cfg .encap_err_rcv in order to allow
the L2TP code to handle ICMP errors;
* only implement error-handling for tunnels which have a managed
socket: unmanaged tunnels using a kernel socket have no userspace to
report errors back to;
* flag the error on the socket, which allows for userspace to get an
error such as -ECONNREFUSED back from sendmsg/recvmsg;
* pass the error into ip[v6]_icmp_error() which allows for userspace to
get extended error information via. MSG_ERRQUEUE.

Most of the callers of erofs_read_metabuf() have the following form:
block = erofs_blknr(sb, offset);
off = erofs_blkoff(sb, offset);
p = erofs_read_metabuf(...., erofs_pos(sb, block), ...);
if (IS_ERR(p))
return PTR_ERR(p);
q = p + off;
// no further uses of p, block or off.
The value passed to erofs_read_metabuf() is offset rounded down to block
size, i.e. offset - off. Passing offset as-is would increase the return
value by off in case of success and keep the return value unchanged in
in case of error. In other words, the same could be achieved by
q = erofs_read_metabuf(...., offset, ...);
if (IS_ERR(q))
return PTR_ERR(q);
This commit convert these simple cases.

Force the max_register of the test regmap to be one register longer
than the number of test registers, to prevent an array overflow in
the test loop.
The test defines num_reg_defaults = 6. With 6 registers and
stride == 2 the valid register addresses would be 0, 2, 4, 6, 8, 10.
However the loop checks attempting to access the odd address, so on
the final register it accesses address 11, and it writes entry [11]
of the read/written arrays.
Originally this worked because the max_register of the regmap was
hardcoded to be BLOCK_TEST_SIZE (== 12).
commit 710915743d53 ("regmap: kunit: Run sparse cache tests at non-zero
register addresses")
introduced the ability to start the test address range from any address,
which means adjusting the max_register. If max_register was not forced,
it was calculated either from num_reg_defaults or BLOCK_TEST_SIZE. This
correctly calculated that with num_reg_defaults == 6 and stride == 2 the
final valid address is 10. So the read/written arrays are allocated to
contain entries [0..10]. When stride attempted to access [11] it was
overflowing the array.

The legacy decompressor has elaborate logic to ensure that the
randomized physical placement of the decompressed kernel image does not
conflict with any memory reservations, including ones specified on the
command line using mem=, memmap=, efi_fake_mem= or hugepages=, which are
taken into account by the kernel proper at a later stage.
When booting in EFI mode, it is the firmware's job to ensure that the
chosen range does not conflict with any memory reservations that it
knows about, and this is trivially achieved by using the firmware's
memory allocation APIs.
That leaves reservations specified on the command line, though, which
the firmware knows nothing about, as these regions have no other special
significance to the platform. Since commit
a1b87d54f4e4 ("x86/efistub: Avoid legacy decompressor when doing EFI boot")
these reservations are not taken into account when randomizing the
physical placement, which may result in conflicts where the memory
cannot be reserved by the kernel proper because its own executable image
resides there.
To avoid having to duplicate or reuse the existing complicated logic,
disable physical KASLR entirely when such overrides are specified. These
are mostly diagnostic tools or niche features, and physical KASLR (as
opposed to virtual KASLR, which is much more important as it affects the
memory addresses observed by code executing in the kernel) is something
we can live without.

Commit 9ad18043fb35 ("thermal: core: Send trip crossing notifications
at init time if needed") overlooked the case when a trip point that
has started as invalid is set to a valid temperature later. Namely,
the initial threshold value for all trips is zero, so if a previously
invalid trip becomes valid and its (new) low temperature is above the
zone temperature, a spurious trip crossing notification will occur and
it may trigger the WARN_ON() in handle_thermal_trip().
To address this, set the initial threshold for all trips to INT_MAX.
There is also the case when a valid writable trip becomes invalid that
requires special handling. First, in accordance with the change
mentioned above, the trip's threshold needs to be set to INT_MAX to
avoid the same issue. Second, if the trip in question is passive and
it has been crossed by the thermal zone temperature on the way up, the
zone's passive count has been incremented and it is in the passive
polling mode, so its passive count needs to be adjusted to allow the
passive polling to be turned off eventually.

The required_opp_tables parsing is not perfect, as the OPP core does the
parsing solely based on the DT node pointers.
The core sets the required_opp_tables entry to the first OPP table in
the "opp_tables" list, that matches with the node pointer.
If the target DT OPP table is used by multiple devices and they all
create separate instances of 'struct opp_table' from it, then it is
possible that the required_opp_tables entry may be set to the incorrect
sibling device.
Unfortunately, there is no clear way to initialize the right values
during the initial parsing and we need to do this at a later point of
time.
Cross check the OPP table again while the genpds are attached and fix
them if required.
Also add a new API for the genpd core to fetch the device pointer for
the genpd.

Commit 262fc47ac174 ('xen/balloon: don't use PV mode extra memory for zone
device allocations') removed the addition of the extra memory ranges to the
unpopulated range allocator, using those only for the balloon driver.
This forces the unpopulated allocator to attach hotplug ranges even when spare
memory (as part of the extra memory ranges) is available. Furthermore, on PVH
domains it defeats the purpose of commit 38620fc4e893 ('x86/xen: attempt to
inflate the memory balloon on PVH'), as extra memory ranges would only be
used to map foreign memory if the kernel is built without XEN_UNPOPULATED_ALLOC
support.
Fix this by adding a helpers that adds the extra memory ranges to the list of
unpopulated pages, and zeroes the ranges so they are not also consumed by the
balloon driver.
This should have been part of 38620fc4e893, hence the fixes tag.
Note the current logic relies on unpopulated_init() (and hence
arch_xen_unpopulated_init()) always being called ahead of balloon_init(), so
that the extra memory regions are consumed by arch_xen_unpopulated_init().

Use try_cmpxchg() instead of cmpxchg(*ptr, old, new) == old.
The x86 CMPXCHG instruction returns success in the ZF flag,
so this change saves a compare after CMPXCHG.
Also, try_cmpxchg() implicitly assigns old *ptr value to "old"
when CMPXCHG fails. There is no need to explicitly assign
old *ptr value to the temporary, which can simplify the
surrounding source code.
No functional change intended.

cpu_max_write()
In the cgroup v2 CPU subsystem, assuming we have a
cgroup named 'test', and we set cpu.max and cpu.max.burst:
# echo 1000000 > /sys/fs/cgroup/test/cpu.max
# echo 1000000 > /sys/fs/cgroup/test/cpu.max.burst
then we check cpu.max and cpu.max.burst:
# cat /sys/fs/cgroup/test/cpu.max
1000000 100000
# cat /sys/fs/cgroup/test/cpu.max.burst
1000000
Next we set cpu.max again and check cpu.max and
cpu.max.burst:
# echo 2000000 > /sys/fs/cgroup/test/cpu.max
# cat /sys/fs/cgroup/test/cpu.max
2000000 100000
# cat /sys/fs/cgroup/test/cpu.max.burst
1000
... we find that the cpu.max.burst value changed unexpectedly.
In cpu_max_write(), the unit of the burst value returned
by tg_get_cfs_burst() is microseconds, while in cpu_max_write(),
the burst unit used for calculation should be nanoseconds,
which leads to the bug.
To fix it, get the burst value directly from tg->cfs_bandwidth.burst.

Change se->load.weight to se_weight(se) in the calculation for the
initial util_avg to avoid unnecessarily inflating the util_avg by 1024
times.
The reason is that se->load.weight has the unit/scale as the scaled-up
load, while cfs_rg->avg.load_avg has the unit/scale as the true task
weight (as mapped directly from the task's nice/priority value). With
CONFIG_32BIT, the scaled-up load is equal to the true task weight. With
CONFIG_64BIT, the scaled-up load is 1024 times the true task weight.
Thus, the current code may inflate the util_avg by 1024 times. The
follow-up capping will not allow the util_avg value to go wild. But the
calculation should have the correct logic.

Commit in Fixes moved the optimize_nops() call inside apply_relocation()
and made it a second optimization pass after the relocations have been
done.
Since optimize_nops() works only on NOPs, that is fine and it'll simply
jump over instructions which are not NOPs.
However, it made that call with repl_len as the buffer length to
optimize.
However, it can happen that there are alternatives calls like this one:
alternative("mfence; lfence", "", ALT_NOT(X86_FEATURE_APIC_MSRS_FENCE));
where the replacement length is 0. And using repl_len is wrong because
apply_alternatives() expands the buffer size to the length of the source
insn that is being patched, by padding it with one-byte NOPs:
for (; insn_buff_sz < a->instrlen; insn_buff_sz++)
insn_buff[insn_buff_sz] = 0x90;
Long story short: pass the length of the original instruction(s) as the
length of the temporary buffer which to optimize.
Result:
SMP alternatives: feat: 11*32+27, old: (lapic_next_deadline+0x9/0x50 (ffffffff81061829) len: 6), repl: (ffffffff89b1cc60, len: 0) flags: 0x1

falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence

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

"rmmod bonding" causes an oops ever since commit cc317ea3d927 ("bonding:
remove redundant NULL check in debugfs function"). Here are the relevant
functions being called:
bonding_exit()
bond_destroy_debugfs()
debugfs_remove_recursive(bonding_debug_root);
bonding_debug_root = NULL; <--------- SET TO NULL HERE
bond_netlink_fini()
rtnl_link_unregister()
__rtnl_link_unregister()
unregister_netdevice_many_notify()
bond_uninit()
bond_debug_unregister()
(commit removed check for bonding_debug_root == NULL)
debugfs_remove()
simple_recursive_removal()
down_write() -> OOPS
However, reverting the bad commit does not solve the problem completely
because the original code contains a race that could cause the same
oops, although it was much less likely to be triggered unintentionally:
CPU1
rmmod bonding
bonding_exit()
bond_destroy_debugfs()
debugfs_remove_recursive(bonding_debug_root);
CPU2
echo -bond0 > /sys/class/net/bonding_masters
bond_uninit()
bond_debug_unregister()
if (!bonding_debug_root)
CPU1
bonding_debug_root = NULL;
So do NOT revert the bad commit (since the removed checks were racy
anyway), and instead change the order of actions taken during module
removal. The same oops can also happen if there is an error during
module init, so apply the same fix there.

Problem
=========
After commit 67f695134703 ("ipv6: Move setting default metric for routes"),
we noticed that the logic of assigning the default value of fc_metirc
changed in the ioctl process. That is, when users use ioctl(fd, SIOCADDRT,
rt) with a non-zero metric to add a route, then they may fail to delete a
route with passing in a metric value of 0 to the kernel by ioctl(fd,
SIOCDELRT, rt). But iproute can succeed in deleting it.
As a reference, when using iproute tools by netlink to delete routes with
a metric parameter equals 0, like the command as follows:
ip -6 route del fe80::/64 via fe81::5054:ff:fe11:3451 dev eth0 metric 0
the user can still succeed in deleting the route entry with the smallest
metric.
Root Reason
===========
After commit 67f695134703 ("ipv6: Move setting default metric for routes"),
When ioctl() pass in SIOCDELRT with a zero metric, rtmsg_to_fib6_config()
will set a defalut value (1024) to cfg->fc_metric in kernel, and in
ip6_route_del() and the line 4074 at net/ipv3/route.c, it will check by
if (cfg->fc_metric && cfg->fc_metric != rt->fib6_metric)
continue;
and the condition is true and skip the later procedure (deleting route)
because cfg->fc_metric != rt->fib6_metric. But before that commit,
cfg->fc_metric is still zero there, so the condition is false and it
will do the following procedure (deleting).
Solution
========
In order to keep a consistent behaviour across netlink() and ioctl(), we
should allow to delete a route with a metric value of 0. So we only do
the default setting of fc_metric in route adding.

The btf_dump test fails:

The "fop_flags" is a recent addition to the struct file_operations in

TASK_SIZE_MAX should be set to a constant value, at least the largest
valid userspace address under any runtime configuration. This optimizes
the check in __access_ok(), which no longer needs to compute the runtime
value of TASK_SIZE. The check does not need to be exact, as long as it
accepts all valid userspace addresses and rejects all valid kernel
addresses; well-behaved programs will never fail the access_ok() check.
For RISC-V, which requires all virtual addresses to be sign extended,
the optimal choice is LONG_MAX because it simplifies the limit
comparison to a sign bit test.
This removes about half of the references to pgtable_l[45]_enabled.

On runtime resume, pci_dev_wait() is called:
pci_pm_runtime_resume()
pci_pm_bridge_power_up_actions()
pci_bridge_wait_for_secondary_bus()
pci_dev_wait()
While a device is runtime suspended along with its PCI hierarchy, the
device could get disconnected. In such case, the link will not come up no
matter how long pci_dev_wait() waits for it.
Besides the above mentioned case, there could be other ways to get the
device disconnected while pci_dev_wait() is waiting for the link to come
up.
Make pci_dev_wait() exit if the device is already disconnected to avoid
unnecessary delay.
The use cases of pci_dev_wait() boil down to two:
1. Waiting for the device after reset
2. pci_bridge_wait_for_secondary_bus()
The callers in both cases seem to benefit from propagating the
disconnection as error even if device disconnection would be more
analoguous to the case where there is no device in the first place which
return 0 from pci_dev_wait(). In the case 2, it results in unnecessary
marking of the devices disconnected again but that is just harmless extra
work.
Also make sure compiler does not become too clever with dev->error_state
and use READ_ONCE() to force a fetch for the up-to-date value.

Arul, Mateusz, Imcarneiro91, and Aman reported a regression caused by
07eab0901ede ("efi/x86: Remove EfiMemoryMappedIO from E820 map"). On the
Lenovo Legion 9i laptop, that commit removes the ECAM area from E820, which
means the early E820 validation fails, which means we don't enable ECAM in
the "early MCFG" path.
The static MCFG table describes ECAM without depending on the ACPI
interpreter. Many Legion 9i ACPI methods rely on that, so they fail when
PCI config access isn't available, resulting in the embedded controller,
PS/2, audio, trackpad, and battery devices not being detected. The _OSC
method also fails, so Linux can't take control of the PCIe hotplug, PME,
and AER features:

PCI: ECAM [mem 0xc0000000-0xce0fffff] reserved to work around lack of ACPI motherboard _CRS
Per PCI Firmware r3.3, sec 4.1.2, ECAM space must be reserved by a PNP0C02
resource, but there's no requirement to mention it in E820, so we shouldn't
look at E820 to validate the ECAM space described by MCFG.
In 2006, 946f2ee5c731 ("[PATCH] i386/x86-64: Check that MCFG points to an
e820 reserved area") added a sanity check of E820 to work around buggy MCFG
tables, but that over-aggressive validation causes failures like this one.
Keep the E820 validation check for machines older than 2016, an arbitrary
ten years after 946f2ee5c731, so machines that depend on it don't break.
Skip the early E820 check for 2016 and newer BIOSes since there's no
requirement to describe ECAM in E820.

It is reported that _DSM evaluation fails in ucsi_acpi_dsm() on Lenovo
IdeaPad Pro 5 due to a missing address space handler for the EC address
space:
ACPI Error: No handler for Region [ECSI] (000000007b8176ee) [EmbeddedControl] (20230628/evregion-130)
This happens because if there is no ECDT, the EC driver only registers
the EC address space handler for operation regions defined in the EC
device scope of the ACPI namespace while the operation region being
accessed by the _DSM in question is located beyond that scope.
To address this, modify the ACPI EC driver to install the EC address
space handler at the root of the ACPI namespace for the first EC that
can be found regardless of whether or not an ECDT is present.
Note that this change is consistent with some examples in the ACPI
specification in which EC operation regions located outside the EC
device scope are used (for example, see Section 9.17.15 in ACPI 6.5),
so the current behavior of the EC driver is arguably questionable.

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

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

Currently ALSA timer doesn't have the lower limit of the start tick
time, and it allows a very small size, e.g. 1 tick with 1ns resolution
for hrtimer. Such a situation may lead to an unexpected RCU stall,
where the callback repeatedly queuing the expire update, as reported
by fuzzer.
This patch introduces a sanity check of the timer start tick time, so
that the system returns an error when a too small start size is set.
As of this patch, the lower limit is hard-coded to 100us, which is
small enough but can still work somehow.

A few of the ROHM PMICs allow setting low-power state specific voltages
for regulators. These voltages are then taken in use (by the hardware)
when the PMIC state is changed.
The voltages for these states can be given via device-tree. If
unsupported voltage has been given, the users have only seen print:
"driver callback failed to parse DT for regulator <name>". This does
help to pinpoint the problem to some extent, but there may be several
properties in device-tree so it should help if we can be a bit more
specific.
Print the voltage value and the run-state property if voltage can not be
supported.

Some of the regulators on the BD71828 have common voltage setting for
RUN/SUSPEND/IDLE/LPSR states. The enable control can be set for each
state though.
The driver allows setting the voltage values for these states via
device-tree. As a side effect, setting the voltages for
SUSPEND/IDLE/LPSR will also change the RUN level voltage which is not
desired and can break the system.
The comment in code reflects this behaviour, but it is likely to not
make people any happier. The right thing to do is to allow setting the
enable/disable state at SUSPEND/IDLE/LPSR via device-tree, but to
disallow setting state specific voltages for those regulators.
BUCK1 is a bit different. It only shares the SUSPEND and LPSR state
voltages. The former behaviour of allowing to silently overwrite the
SUSPEND state voltage by LPSR state voltage is also changed here so that
the SUSPEND voltage is prioritized over LPSR voltage.
Prevent setting PMIC state specific voltages for regulators which do not
support it.

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

With the mentioned commit (see the fixes tag) on every AP bus scan an
uevent "AP bus change bindings complete" is emitted. Furthermore if an AP
device switched from one driver to another, for example by manipulating the
apmask, there was never a "bindings complete" uevent generated.
The "bindings complete" event should be sent once when all AP devices have
been bound to device drivers and again if unbind/bind actions take place
and finally all AP devices are bound again. Therefore implement this.

Kernel panic - not syncing: Fatal exception: panic_on_oops
occured when /sys/bus/ap/a[pq]mask was updated with a relative mask value
(like +0x10-0x12,+60,-90) with one of the numeric values exceeding INT_MAX.
The fix is simple: use unsigned long values for the internal variables. The
correct checks are already in place in the function but a simple int for
the internal variables was used with the possibility to overflow.

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

During a cgroup_rstat_flush() call, the lowest level of nodes are flushed
first before their parents. Since commit 3b8cc6298724 ("blk-cgroup:
Optimize blkcg_rstat_flush()"), iostat propagation was still done to
the parent. Grandparent, however, may not get the iostat update if the
parent has no blkg_iostat_set queued in its lhead lockless list.
Fix this iostat propagation problem by queuing the parent's global
blkg->iostat into one of its percpu lockless lists to make sure that
the delta will always be propagated up to the grandparent and so on
toward the root blkcg.
Note that successive calls to __blkcg_rstat_flush() are serialized by
the cgroup_rstat_lock. So no special barrier is used in the reading
and writing of blkg->iostat.lqueued.

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

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

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

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

Remove wrong mask on subsys_vendor_id. Both the Vendor ID and Subsystem
Vendor ID are u16 variables and are written to a u32 register of the
controller. The Subsystem Vendor ID was always 0 because the u16 value
was masked incorrectly with GENMASK(31,16) resulting in all lower 16
bits being set to 0 prior to the shift.
Remove both masks as they are unnecessary and set the register correctly
i.e., the lower 16-bits are the Vendor ID and the upper 16-bits are the
Subsystem Vendor ID.
This is documented in the RK3399 TRM section 17.6.7.1.17

"Finally something fun. Mike Rapoport does some cleanup to allow us to

It starts with a non-functional changes API rename / placeholders to
then allow architectures to define their requirements into a new shiny

Archs now can intitialize this execmem_info as the last part of
mm_core_init() if they have to diverge from the norm. Each range is a
known type clearly articulated and spelled out in enum execmem_type.

Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang. It was re-enabled in the
kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow
sanitizer").
Let's rearrange the check to not perform any arithmetic, thus not
tripping the sanitizer.
