Current minimum required version of binutils is 2.25,
which supports PAUSE instruction mnemonic.
Replace "REP; NOP" with this proper mnemonic.
No functional change intended.

um_pci_init() open-codes what the irq_domain_create_linear() helper
does already. Use the helper instead of open-coding it.

Implement a new virtual PCI driver based on the VFIO framework.
This driver allows users to pass through PCI devices to UML via
VFIO. Currently, only MSI-X capable devices are supported, and
it is assumed that drivers will use MSI-X.

Segfaults can occur at times where the mmap lock cannot be taken. If
that happens the segfault handler may not be able to take the mmap lock.
Fix the code to use the same approach as most other architectures.
Unfortunately, this requires copying code from mm/memory.c and modifying
it slightly as UML does not have exception tables.

We send a SIGALRM to userspace processes to interrupt them. Really,
doing so is only needed if they are actually executing at the time (to
ensure we return to kernelspace). Unfortunately, we do not have that
information readily available. We can however be sure that this is never
the case when we are in time-travel mode with infinite CPU.

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.

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

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.

which this is enabled and visible for end users. It usually doesn't
correspond to the version in which the patch was developed, but rather a

On some paths in print_event_fields() it takes the trace_event_sem for
read, even though it should always be held when the function is called.
Remove the taking of that mutex and add a lockdep_assert_held_read() to
make sure the trace_event_sem is held when print_event_fields() is called.

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
a false positive detection of an out of bounds write caused by
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.
