Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Paolo Bonzini:
"The bulk of the changes here is a largish change to guest_memfd,
delaying the clearing and encryption of guest-private pages until they
are actually added to guest page tables. This started as "let's make
it impossible to misuse the API" for SEV-SNP; but then it ballooned a
bit.
The new logic is generally simpler and more ready for hugepage support
in guest_memfd.
Summary:
- fix latent bug in how usage of large pages is determined for
confidential VMs
- fix "underline too short" in docs
- eliminate log spam from limited APIC timer periods
- disallow pre-faulting of memory before SEV-SNP VMs are initialized
- delay clearing and encrypting private memory until it is added to
guest page tables
- this change also enables another small cleanup: the checks in
SNP_LAUNCH_UPDATE that limit it to non-populated, private pages can

The current "nretries > 1 || nretries >= max_retries" check in
cs_watchdog_read() will always evaluate to true, and thus pr_warn(), if
nretries is greater than 1. The intent is instead to never warn on the
first try, but otherwise warn if the successful retry was the last retry.
Therefore, change that "||" to "&&".

NetApp server requires the file to be open with FILE_READ_EA access in
order to support FSCTL_GET_REPARSE_POINT, otherwise it will return
STATUS_INVALID_DEVICE_REQUEST. It doesn't make any sense because
there's no requirement for FILE_READ_EA bit to be set nor
STATUS_INVALID_DEVICE_REQUEST being used for something other than
"unsupported reparse points" in MS-FSA.
To fix it and improve compatibility, set FILE_READ_EA & SYNCHRONIZE
bits to match what Windows client currently does.

Although the Arm architecture permits concurrent modification and
execution of NOP and branch instructions, it still requires some
synchronisation to ensure that other CPUs consistently execute the newly
written instruction:
> When the modified instructions are observable, each PE that is
> executing the modified instructions must execute an ISB or perform a
> context synchronizing event to ensure execution of the modified
> instructions
Prior to commit f6cc0c501649 ("arm64: Avoid calling stop_machine() when
patching jump labels"), the arm64 jump_label patching machinery
performed synchronisation using stop_machine() after each modification,
however this was problematic when flipping static keys from atomic
contexts (namely, the arm_arch_timer CPU hotplug startup notifier) and
so we switched to the _nosync() patching routines to avoid "scheduling
while atomic" BUG()s during boot.
In hindsight, the analysis of the issue in f6cc0c501649 isn't quite
right: it cites the use of IPIs in the default patching routines as the
cause of the lockup, whereas stop_machine() does not rely on IPIs and
the I-cache invalidation is performed using __flush_icache_range(),
which elides the call to kick_all_cpus_sync(). In fact, the blocking
wait for other CPUs is what triggers the BUG() and the problem remains
even after f6cc0c501649, for example because we could block on the
jump_label_mutex. Eventually, the arm_arch_timer driver was fixed to
avoid the static key entirely in commit a862fc2254bd
("clocksource/arm_arch_timer: Remove use of workaround static key").
This all leaves the jump_label patching code in a funny situation on
arm64 as we do not synchronise with other CPUs to reduce the likelihood
of a bug which no longer exists. Consequently, toggling a static key on
one CPU cannot be assumed to take effect on other CPUs, leading to
potential issues, for example with missing preempt notifiers.
Rather than revert f6cc0c501649 and go back to stop_machine() for each
patch site, implement arch_jump_label_transform_apply() and kick all
the other CPUs with an IPI at the end of patching.

In an unrelated change, the two syscalls are no longer architecture

Despite multiple attempts to get the syscall number assignment right
for the newly added uretprobe syscall, we ended up with a bit of a mess:
- The number is defined as 467 based on the assumption that the
xattrat family of syscalls would use 463 through 466, but those
did not make it into 6.11.
- The include/uapi/asm-generic/unistd.h file still lists the number
463, but the new scripts/syscall.tbl that was supposed to have the
same data lists 467 instead as the number for arc, arm64, csky,
hexagon, loongarch, nios2, openrisc and riscv. None of these
architectures actually provide a uretprobe syscall.
- All the other architectures (powerpc, arm, mips, ...) don't list
this syscall at all.
There are two ways to make it consistent again: either list it with
the same syscall number on all architectures, or only list it on x86
but not in scripts/syscall.tbl and asm-generic/unistd.h.
Based on the most recent discussion, it seems like we won't need it
anywhere else, so just remove the inconsistent assignment and instead
move the x86 number to the next available one in the architecture
specific range, which is 335.

The microphone/speaker privacy shutter ALSA control handlers need to
call pm_runtime_resume, since the hardware needs to be powered up to
check the hardware state of the shutter. The IRQ handler for the
shutters also needs to notify the ALSA control to inform user-space

between the sdw_dev_lock and the controls_rwsem.
To avoid this mutex inversion cache the kctl pointers before the IRQ

Commit 804e498e0496 ("sd: convert to the atomic queue limits API")
introduced pairs of function calls to queue_limits_start_update() and
queue_limits_commit_update(). These two functions lock and unlock
q->limits_lock. In sd_revalidate_disk(), sd_read_cpr() is called after
queue_limits_start_update() call and before queue_limits_commit_update()
call. sd_read_cpr() locks q->sysfs_dir_lock and &q->sysfs_lock. Then new
lock dependencies were created between q->limits_lock, q->sysfs_dir_lock
and q->sysfs_lock, as follows:
sd_revalidate_disk
queue_limits_start_update
mutex_lock(&q->limits_lock)
sd_read_cpr
disk_set_independent_access_ranges
mutex_lock(&q->sysfs_dir_lock)
mutex_lock(&q->sysfs_lock)
mutex_unlock(&q->sysfs_lock)
mutex_unlock(&q->sysfs_dir_lock)
queue_limits_commit_update
mutex_unlock(&q->limits_lock)
However, the three locks already had reversed dependencies in other
places. Then the new dependencies triggered the lockdep WARN "possible
circular locking dependency detected" [1]. This WARN was observed by
running the blktests test case srp/002.
To avoid the WARN, move the sd_read_cpr() call in sd_revalidate_disk()
after the queue_limits_commit_update() call. In other words, move the
sd_read_cpr() call out of the q->limits_lock region.

====================
mptcp: fix endpoints with 'signal' and 'subflow' flags
When looking at improving the user experience around the MPTCP endpoints
setup, I noticed that setting an endpoint with both the 'signal' and the
'subflow' flags -- as it has been done in the past by users according to
bug reports we got -- was resulting on only announcing the endpoint, but
not using it to create subflows: the 'subflow' flag was then ignored.
My initial thought was to modify IPRoute2 to warn the user when the two
flags were set, but it doesn't sound normal to ignore one of them. I
then looked at modifying the kernel not to allow having the two flags
set, but when discussing about that with Mat, we thought it was maybe
not ideal to do that, as there might be use-cases, we might break some
configs. Then I saw it was working before v5.17. So instead, I fixed the
support on the kernel side (patch 5) using Paolo's suggestion. This also
includes a fix on the options side (patch 1: for v5.11+), an explicit
deny of some options combinations (patch 2: for v5.18+), and some
refactoring (patches 3 and 4) to ease the inclusion of the patch 5.
While at it, I added a new selftest (patch 7) to validate this case --
including a modification of the chk_add_nr helper to inverse the sides
were the counters are checked (patch 6) -- and allowed ADD_ADDR echo
just after the MP_JOIN 3WHS.
The selftests modification have the same Fixes tag as the previous
commit, but no 'Cc: Stable': if the backport can work, that's good --
but it still need to be verified by running the selftests -- if not, no
need to worry, many CIs will use the selftests from the last stable
version to validate previous stable releases.

It should be quite uncommon to set both the subflow and the signal
flags: the initiator of the connection is typically the one creating new
subflows, not the other peer, then no need to announce additional local
addresses, and use it to create subflows.
But some people might be confused about the flags, and set both "just to
be sure at least the right one is set". To verify the previous fix, and
avoid future regressions, this specific case is now validated: the
client announces a new address, and initiates a new subflow from the
same address.
While working on this, another bug has been noticed, where the client
reset the new subflow because an ADD_ADDR echo got received as the 3rd
ACK: this new test also explicitly checks that no RST have been sent by
the client and server.
The 'Fixes' tag here below is the same as the one from the previous

Up to the 'Fixes' commit, having an endpoint with both the 'signal' and
'subflow' flags, resulted in the creation of a subflow and an address
announcement using the address linked to this endpoint. After this
commit, only the address announcement was done, ignoring the 'subflow'
flag.
That's because the same bitmap is used for the two flags. It is OK to
keep this single bitmap, the already selected local endpoint simply have
to be re-used, but not via select_local_address() not to look at the
just modified bitmap.
Note that it is unusual to set the two flags together: creating a new
subflow using a new local address will implicitly advertise it to the
other peer. So in theory, no need to advertise it explicitly as well.
Maybe there are use-cases -- the subflow might not reach the other peer
that way, we can ask the other peer to try initiating the new subflow
without delay -- or very likely the user is confused, and put both flags
"just to be sure at least the right one is set". Still, if it is
allowed, the kernel should do what has been asked: using this endpoint
to announce the address and to create a new subflow from it.
An alternative is to forbid the use of the two flags together, but
that's probably too late, there are maybe use-cases, and it was working
before. This patch will avoid people complaining subflows are not
created using the endpoint they added with the 'subflow' and 'signal'
flag.
Note that with the current patch, the subflow might not be created in
some corner cases, e.g. if the 'subflows' limit was reached when sending
the ADD_ADDR, but changed later on. It is probably not worth splitting
id_avail_bitmap per target ('signal', 'subflow'), which will add another
large field to the msk "just" to track (again) endpoints. Anyway,
currently when the limits are changed, the kernel doesn't check if new
subflows can be created or removed, because we would need to keep track
of the received ADD_ADDR, and more. It sounds OK to assume that the
limits should be properly configured before establishing new
connections.

feature cannot work with the 'subflow' flag.
Technically, if both the 'signal' and 'subflow' flags are set, it will
be possible to create the listening socket, but not to establish a
subflow using this source port. So better to explicitly deny it, not to
create some confusions because the expected behaviour is not possible.

Before this patch, receiving an ADD_ADDR echo on the just connected
MP_JOIN subflow -- initiator side, after the MP_JOIN 3WHS -- was
resulting in an MP_RESET. That's because only ACKs with a DSS or
ADD_ADDRs without the echo bit were allowed.
Not allowing the ADD_ADDR echo after an MP_CAPABLE 3WHS makes sense, as
we are not supposed to send an ADD_ADDR before because it requires to be
in full established mode first. For the MP_JOIN 3WHS, that's different:
the ADD_ADDR can be sent on a previous subflow, and the ADD_ADDR echo
can be received on the recently created one. The other peer will already
be in fully established, so it is allowed to send that.
We can then relax the conditions here to accept the ADD_ADDR echo for
MPJ subflows.

both callers have verified that fd is not greater than ->max_fds;
however, misprediction might end up with
tofree = fdt->fd[fd];
being speculatively executed. That's wrong for the same reasons
why it's wrong in close_fd()/file_close_fd_locked(); the same
solution applies - array_index_nospec(fd, fdt->max_fds) could differ
from fd only in case of speculative execution on mispredicted path.

While zeroing the upper 32 bits of an 8-byte getuser on 32-bit x86 was
fixed by commit 8c860ed825cb ("x86/uaccess: Fix missed zeroing of ia32 u64
get_user() range checking") it was broken again in commit 8a2462df1547
("x86/uaccess: Improve the 8-byte getuser() case").
This is because the register which holds the upper 32 bits (%ecx) is being
cleared _after_ the check_range, so if the range check fails, %ecx is never
cleared.
This can be reproduced with:
./tools/testing/kunit/kunit.py run --arch i386 usercopy
Instead, clear %ecx _before_ check_range in the 8-byte case. This
reintroduces a bit of the ugliness we were trying to avoid by adding
another #ifndef CONFIG_X86_64, but at least keeps check_range from needing
a separate bad_get_user_8 jump.

The RISC-V kernel already has checks to ensure that memory which would
lie outside of the linear mapping is not used. However those checks
use memory_limit, which is used to implement the mem= kernel command
line option (to limit the total amount of memory, not its address
range). When memory is made up of two or more non-contiguous memory
banks this check is incorrect.
Two changes are made here:
- add a call in setup_bootmem() to memblock_cap_memory_range() which
will cause any memory which falls outside the linear mapping to be
removed from the memory regions.
- remove the check in create_linear_mapping_page_table() which was
intended to remove memory which is outside the liner mapping based
on memory_limit, as it is no longer needed. Note a check for
mapping more memory than memory_limit (to implement mem=) is
unnecessary because of the existing call to
memblock_enforce_memory_limit().
This issue was seen when booting on a SV39 platform with two memory
banks:
0x00,80000000 1GiB
0x20,00000000 32GiB
This memory range is 158GiB from top to bottom, but the linear mapping
is limited to 128GiB, so the lower block of RAM will be mapped at
PAGE_OFFSET, and the upper block straddles the top of the linear
mapping.
This causes the following Oops:

The problem is that memblock (unaware that some physical memory cannot
be used) has allocated memory from the top of memory but which is
outside the linear mapping region.

"Resources present before probing" (Philipp Stanner)
- Fix a pciehp regression that clobbered the upper bits of RAID status
LEDs on NVMe devices behind an Intel VMD (Blazej Kucman)

The `if (req_max_level)` test was meant ignore req_max_level if
PG_LEVEL_NONE was returned. Hence, this function should return
max_level instead of the ignored req_max_level.
This is only a latent issue for now, since guest_memfd does not
support large pages.

The sysfs "attention" file normally controls the Slot Control Attention
Indicator with 0 (off), 1 (on), 2 (blink) settings.
576243b3f9ea ("PCI: pciehp: Allow exclusive userspace control of
indicators") added pciehp_set_raw_indicator_status() to allow userspace to
directly control all four bits in both the Attention Indicator and the
Power Indicator fields via the "attention" file.
This is used on Intel VMD bridges so utilities like "ledmon" can use sysfs
"attention" to control up to 16 indicators for NVMe device RAID status.
abaaac4845a0 ("PCI: hotplug: Use FIELD_GET/PREP()") broke this by masking
the sysfs data with PCI_EXP_SLTCTL_AIC, which discards the upper two bits
intended for the Power Indicator Control field (PCI_EXP_SLTCTL_PIC).
For NVMe devices behind an Intel VMD, ledmon settings that use the
PCI_EXP_SLTCTL_PIC bits, i.e., ATTENTION_REBUILD (0x5), ATTENTION_LOCATE
(0x7), ATTENTION_FAILURE (0xD), ATTENTION_OFF (0xF), no longer worked
correctly.
Mask with PCI_EXP_SLTCTL_AIC | PCI_EXP_SLTCTL_PIC to retain both the
Attention Indicator and the Power Indicator bits.

pci_intx() becomes managed if pcim_enable_device() has been called in
advance. Commit 25216afc9db5 ("PCI: Add managed pcim_intx()") changed this
behavior so that pci_intx() always leads to creation of a separate device
resource for itself, whereas earlier, a shared resource was used for all
PCI devres operations.
Unfortunately, pci_intx() seems to be used in some drivers' remove() paths;
in the managed case this causes a device resource to be created on driver
detach, which causes .probe() to fail if the driver is reloaded:
pci 0000:00:1f.2: Resources present before probing
Fix the regression by only redirecting pci_intx() to its managed twin
pcim_intx() if the pci_command changes.
