When compressed data deduplication is enabled, multiple logical extents
may reference the same compressed physical cluster.
The previous commit 94c43de73521 ("erofs: fix wrong primary bvec
selection on deduplicated extents") already avoids using shortened
bvecs. However, in such cases, the extra temporary buffers also
need to be preserved for later use in z_erofs_fill_other_copies() to
to prevent data corruption.
IOWs, extra temporary buffers have to be retained not only due to
varying start relative offsets (`pageofs_out`, as indicated by
`pcl->multibases`) but also because of shortened bvecs.

...
Both 204185 and 54095257 have the same start relative offset of 3481,
but the logical page 55 of `android.hardware.graphics.composer@2.1.so`
ranges from 225280 to 229632, forming a shortened bvec [225280, 225536)
that cannot be used for decompressing the range from 54095257 to
54309344 of `com.android.vndk.v28.apex`.
Since `pcl->multibases` is already meaningless, just mark `be->keepxcpy`
on demand for simplicity.
Again, this issue can only lead to data corruption if `-Ededupe` is on.

Nathan reported [1] that when built with clang, the um kernel
crashes pretty much immediately. This turned out to be an issue
with the inline assembly I had added, when clang used %rax/%eax
for both operands. Reorder it so current->thread.segv_continue
is written first, and then the lifetime of _faulted won't have
overlap with the lifetime of segv_continue.
In the email thread Benjamin also pointed out that current->mm
is only NULL for true kernel tasks, but we could do this for a
userspace task, so the current->thread.segv_continue logic must
be lifted out of the mm==NULL check.
Finally, while looking at this, put a barrier() so the NULL
assignment to thread.segv_continue cannot be reorder before
the possibly faulting operation.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Fix read out of bounds bug in tracing_splice_read_pipe()
The size of the sub page being read can now be greater than a page.
But the buffer used in tracing_splice_read_pipe() only allocates a
page size. The data copied to the buffer is the amount in sub buffer
which can overflow the buffer.
Use min((size_t)trace_seq_used(&iter->seq), PAGE_SIZE) to limit the
amount copied to the buffer to a max of PAGE_SIZE.
- Fix the test for NULL from "!filter_hash" to "!*filter_hash"
The add_next_hash() function checked for NULL at the wrong pointer
level.
- Do not use the array in trace_adjust_address() if there are no
elements
The trace_adjust_address() finds the offset of a module that was
stored in the persistent buffer when reading the previous boot buffer
to see if the address belongs to a module that was loaded in the
previous boot. An array is created that matches currently loaded
modules with previously loaded modules. The trace_adjust_address()
uses that array to find the new offset of the address that's in the
previous buffer. But if no module was loaded, it ends up reading the
last element in an array that was never allocated.
Check if nr_entries is zero and exit out early if it is.
- Remove nested lock of trace_event_sem in print_event_fields()
The print_event_fields() function iterates over the ftrace_events
list and requires the trace_event_sem semaphore held for read. But
this function is always called with that semaphore held for read.
Remove the taking of the semaphore and replace it with
lockdep_assert_held_read(&trace_event_sem)

"Fix a double SIGFPE crash"
* tag 'parisc-for-6.15-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Fix double SIGFPE crash
|
|
Camm noticed that on parisc a SIGFPE exception will crash an application with
a second SIGFPE in the signal handler. Dave analyzed it, and it happens
because glibc uses a double-word floating-point store to atomically update
function descriptors. As a result of lazy binding, we hit a floating-point
store in fpe_func almost immediately.
When the T bit is set, an assist exception trap occurs when when the
co-processor encounters *any* floating-point instruction except for a double
store of register %fr0. The latter cancels all pending traps. Let's fix this
by clearing the Trap (T) bit in the FP status register before returning to the
signal handler in userspace.
The issue can be reproduced with this test program:
root@parisc:~# cat fpe.c
static void fpe_func(int sig, siginfo_t *i, void *v) {
sigset_t set;
sigemptyset(&set);
sigaddset(&set, SIGFPE);
sigprocmask(SIG_UNBLOCK, &set, NULL);
printf("GOT signal %d with si_code %ld\n", sig, i->si_code);
}
int main() {
struct sigaction action = {
.sa_sigaction = fpe_func,
.sa_flags = SA_RESTART|SA_SIGINFO };
sigaction(SIGFPE, &action, 0);
feenableexcept(FE_OVERFLOW);
return printf("%lf\n",1.7976931348623158E308*1.7976931348623158E308);
}

Commit:
d54d610243a4 ("x86/boot/sev: Avoid shared GHCB page for early memory acceptance")
provided a fix for SEV-SNP memory acceptance from the EFI stub when
running at VMPL #0. However, that fix was insufficient for SVSM SEV-SNP
guests running at VMPL >0, as those rely on a SVSM calling area, which
is a shared buffer whose address is programmed into a SEV-SNP MSR, and
the SEV init code that sets up this calling area executes much later
during the boot.
Given that booting via the EFI stub at VMPL >0 implies that the firmware
has configured this calling area already, reuse it for performing memory
acceptance in the EFI stub.

Merge cpufreq fixes for 6.15-rc5:
- Fix a recent regression causing systems where frequency tables are
used by cpufreq to have issues with setting frequency limits (Rafael
Wysocki).
- Fix a recent regressions causing frequency boost settings to become
out-of-sync if platform firmware updates the registers associated
with them during system resume (Viresh Kumar).
- Fix an unchecked MSR aceess in the intel_pstate driver occurring when
CPUID indicates no turbo, but the driver attempts to enable turbo
frequencies due to a misleading value read from an MSR (Srinivas
Pandruvada).

On Qualcomm chipsets not all GPIOs are wakeup capable. Those GPIOs do not
have a corresponding MPM pin and should not be handled inside the MPM
driver. The IRQ domain hierarchy is always applied, so it's required to
explicitly disconnect the hierarchy for those. The pinctrl-msm driver marks
these with GPIO_NO_WAKE_IRQ. qcom-pdc has a check for this, but
irq-qcom-mpm is currently missing the check. This is causing crashes when
setting up interrupts for non-wake GPIOs:
root@rb1:~# gpiomon -c gpiochip1 10
irq: IRQ159: trimming hierarchy from :soc@0:interrupt-controller@f200000-1
Unable to handle kernel paging request at virtual address ffff8000a1dc3820
Hardware name: Qualcomm Technologies, Inc. Robotics RB1 (DT)
pc : mpm_set_type+0x80/0xcc
lr : mpm_set_type+0x5c/0xcc
Call trace:
mpm_set_type+0x80/0xcc (P)
qcom_mpm_set_type+0x64/0x158
irq_chip_set_type_parent+0x20/0x38

edge_detector_setup+0x260/0x364
linereq_create+0x420/0x5a8
gpio_ioctl+0x2d4/0x6c0
Fix this by copying the check for GPIO_NO_WAKE_IRQ from qcom-pdc.c, so that
MPM is removed entirely from the hierarchy for non-wake GPIOs.

The folio_index() helper is only needed for mixed usage of page cache
and swap cache, for pure page cache usage, the caller can just use
folio->index instead.
It can't be a swap cache folio here. Swap mapping may only call into fs
through 'swap_rw' but btrfs does not use that method for swap.

This reverts commit 7e06de7c83a746e58d4701e013182af133395188.
Commit 7e06de7c83a7 ("btrfs: canonicalize the device path before adding
it") tries to make btrfs to use "/dev/mapper/*" name first, then any
filename inside "/dev/" as the device path.
This is mostly fine when there is only the root namespace involved, but
when multiple namespace are involved, things can easily go wrong for the
d_path() usage.
As d_path() returns a file path that is namespace dependent, the
resulted string may not make any sense in another namespace.
Furthermore, the "/dev/" prefix checks itself is not reliable, one can
still make a valid initramfs without devtmpfs, and fill all needed
device nodes manually.
Overall the userspace has all its might to pass whatever device path for
mount, and we are not going to win the war trying to cover every corner
case.
So just revert that commit, and do no extra d_path() based file path
sanity check.

[BUG]

[CAUSE]
Mount option "rescue=idatacsums" will completely skip loading the csum
tree, so that any data read will not find any data csum thus we will
ignore data checksum verification.
Normally call sites utilizing csum tree will check the fs state flag
NO_DATA_CSUMS bit, but unfortunately scrub does not check that bit at all.
This results in scrub to call btrfs_search_slot() on a NULL pointer
and triggered above crash.
[FIX]
Check both extent and csum tree root before doing any tree search.

for it to return 0 as the number of folios in the eb when the first

btrfs_prelim_ref() calls the old and new reference variables in the
incorrect order. This causes a NULL pointer dereference because oldref
is passed as NULL to trace_btrfs_prelim_ref_insert().
Note, trace_btrfs_prelim_ref_insert() is being called with newref as
oldref (and oldref as NULL) on purpose in order to print out
the values of newref.
To reproduce:
echo 1 > /sys/kernel/debug/tracing/events/btrfs/btrfs_prelim_ref_insert/enable

In preparation for making the kmalloc() family of allocators type aware,
we need to make sure that the returned type from the allocation matches
the type of the variable being assigned. (Before, the allocator would
always return "void *", which can be implicitly cast to any pointer type.)
The assigned type is "struct folio **" but the returned type will be
"struct page **". These are the same allocation size (pointer size), but
the types don't match. Adjust the allocation type to match the assignment.

This actually reverts 86e92eeeb237 ("bcachefs: Annotate struct bch_xattr
with __counted_by()").
After the x_name, there is a value. According to the disscussion[1],
__counted_by assumes that the flexible array member contains exactly
the amount of elements that are specified. Now there are users came across

the __counted_by here[2], so revert that.

The original code would skip null delay pointers, but when the pointers
were converted to point within the spi_device struct, the check was not
updated to skip delays of zero. Hence all spi devices that didn't set
delays would fail to probe.

The function trace_adjust_address() is used to map addresses of modules
stored in the persistent memory and are also loaded in the current boot to
return the current address for the module.
If there's only one module entry, it will simply use that, otherwise it
performs a bsearch of the entry array to find the modules to offset with.
The issue is if there are no modules in the array. The code does not
account for that and ends up referencing the first element in the array
which does not exist and causes a crash.
If nr_entries is zero, exit out early as if this was a core kernel
address.
