dec_pending() is given an error status (possibly 0) to be recorded
against a bio. It can be called several times on the one 'struct
dm_io', and it is careful to only assign a non-zero error to
io->status. However when it then assigned io->status to bio->bi_status,
it is not careful and could overwrite a genuine error status with 0.
This can happen when chained bios are in use. If a bio is chained
beneath the bio that this dm_io is handling, the child bio might
complete and set bio->bi_status before the dm_io completes.
This has been possible since chained bios were introduced in 3.14, and
has become a lot easier to trigger with commit 18a25da84354 ("dm: ensure
bio submission follows a depth-first tree walk") as that commit caused
dm to start using chained bios itself.
A particular failure mode is that if a bio spans an 'error' target and a
working target, the 'error' fragment will complete instantly and set the
->bi_status, and the other fragment will normally complete a little
later, and will clear ->bi_status.
The fix is simply to only assign io_error to bio->bi_status when
io_error is not zero.

On some platforms there's an ITS available but it's not enabled
because reading or writing the registers is denied by the
firmware. In fact, reading or writing them will cause the system
to reset. We could remove the node from DT in such a case, but
it's better to skip nodes that are marked as "disabled" in DT so
that we can describe the hardware that exists and use the status
property to indicate how the firmware has configured things.

A DMB instruction can be used to ensure the relative order of only
memory accesses before and after the barrier. Since writes to system
registers are not memory operations, barrier DMB is not sufficient
for observability of memory accesses that occur before ICC_SGI1R_EL1
writes.
A DSB instruction ensures that no instructions that appear in program
order after the DSB instruction, can execute until the DSB instruction
has completed.

Commit 7778c4b27cbe ("irqchip: mips-gic: Use pcpu_masks to avoid reading
GIC_SH_MASK*") removed the read of the hardware mask register when
handling shared interrupts, instead using the driver's shadow pcpu_masks
entry as the effective mask. Unfortunately this did not take account of
the write to pcpu_masks during gic_shared_irq_domain_map, which
effectively unmasks the interrupt early. If an interrupt is asserted,
gic_handle_shared_int decodes and processes the interrupt even though it
has not yet been unmasked via gic_unmask_irq, which also sets the
appropriate bit in pcpu_masks.
On the MIPS Boston board, when a console command line of
"console=ttyS0,115200n8r" is passed, the modem status IRQ is enabled in
the UART, which is immediately raised to the GIC. The interrupt has been
mapped, but no handler has yet been registered, nor is it expected to be
unmasked. However, the write to pcpu_masks in gic_shared_irq_domain_map
has effectively unmasked it, resulting in endless reports of:
[ 5.058454] irq 13, desc: ffffffff80a7ad80, depth: 1, count: 0, unhandled: 0
[ 5.062057] ->handle_irq(): ffffffff801b1838,
[ 5.062175] handle_bad_irq+0x0/0x2c0
Where IRQ 13 is the UART interrupt.
To fix this, just remove the write to pcpu_masks in
gic_shared_irq_domain_map. The existing write in gic_unmask_irq is the
correct place for what is now the effective unmasking.

binder_send_failed_reply() is called when a synchronous
transaction fails. It reports an error to the thread that
is waiting for the completion. Given that the transaction
is synchronous, there should never be more than 1 error
response to that thread -- this was being asserted with
a WARN().
However, when exercising the driver with syzbot tests, cases
were observed where multiple "synchronous" requests were
sent without waiting for responses, so it is possible that
multiple errors would be reported to the thread. This testing
was conducted with panic_on_warn set which forced the crash.
This is easily reproduced by sending back-to-back
"synchronous" transactions without checking for any
response (eg, set read_size to 0):
bwr.write_buffer = (uintptr_t)&bc1;
bwr.write_size = sizeof(bc1);
bwr.read_buffer = (uintptr_t)&br;
bwr.read_size = 0;
ioctl(fd, BINDER_WRITE_READ, &bwr);
sleep(1);
bwr2.write_buffer = (uintptr_t)&bc2;
bwr2.write_size = sizeof(bc2);
bwr2.read_buffer = (uintptr_t)&br;
bwr2.read_size = 0;
ioctl(fd, BINDER_WRITE_READ, &bwr2);
sleep(1);
The first transaction is sent to the servicemanager and the reply
fails because no VMA is set up by this client. After
binder_send_failed_reply() is called, the BINDER_WORK_RETURN_ERROR
is sitting on the thread's todo list since the read_size was 0 and
the client is not waiting for a response.
The 2nd transaction is sent and the BINDER_WORK_RETURN_ERROR has not
been consumed, so the thread's reply_error.cmd is still set (normally
cleared when the BINDER_WORK_RETURN_ERROR is handled). Therefore
when the servicemanager attempts to reply to the 2nd failed
transaction, the error is already set and it triggers this warning.
This is a user error since it is not waiting for the synchronous
transaction to complete. If it ever does check, it will see an
error.
Changed the WARN() to a pr_warn().

Several i586-class CPUs supporting this instruction are missing from
the X86_CMPXCHG64 config group.
Using a configuration with either M586TSC or M586MMX currently sets
X86_MINIMUM_CPU_FAMILY=4 instead of the correct value of 5.
Booting on an i486 it will fail to generate the "This kernel
requires an i586 CPU, but only detected an i486 CPU" message and
intentional halt as expected. It will instead just silently hang
when it hits i586-specific instructions.
The M586 CPU is not in this list because at least the Cyrix 5x86
lacks this instruction, and perhaps others.

First set of fixes for current -rc cycle. Most of the changes are on
dwc3 this time around (59%) with some function changes (25%).
Out of the those, the most important fixes are:
- EP0 TRB counter fix on dwc3
- dwc3-omap stopped missing events during suspend/resume
- maxpacket size fix for ep0 in dwc3
- Descriptor processing fix for functionfs
Apart from these, your usual set of important-but-not-so-critical
fixes all over the place.

Improve error handling when disarming ftrace-based kprobes. Like with
arm_kprobe_ftrace(), propagate any errors from disarm_kprobe_ftrace() so
that we do not disable/unregister kprobes that are still armed. In other
words, unregister_kprobe() and disable_kprobe() should not report success
if the kprobe could not be disarmed.
disarm_all_kprobes() keeps its current behavior and attempts to
disarm all kprobes. It returns the last encountered error and gives a
warning if not all probes could be disarmed.
This patch is based on Petr Mladek's original patchset (patches 2 and 3)
back in 2015, which improved kprobes error handling, found here:
https://lkml.org/lkml/2015/2/26/452
However, further work on this had been paused since then and the patches
were not upstreamed.

Improve error handling when arming ftrace-based kprobes. Specifically, if
we fail to arm a ftrace-based kprobe, register_kprobe()/enable_kprobe()
should report an error instead of success. Previously, this has lead to
confusing situations where register_kprobe() would return 0 indicating
success, but the kprobe would not be functional if ftrace registration
during the kprobe arming process had failed. We should therefore take any
errors returned by ftrace into account and propagate this error so that we
do not register/enable kprobes that cannot be armed. This can happen if,
for example, register_ftrace_function() finds an IPMODIFY conflict (since
kprobe_ftrace_ops has this flag set) and returns an error. Such a conflict
is possible since livepatches also set the IPMODIFY flag for their ftrace_ops.
arm_all_kprobes() keeps its current behavior and attempts to arm all
kprobes. It returns the last encountered error and gives a warning if
not all probes could be armed.
This patch is based on Petr Mladek's original patchset (patches 2 and 3)
back in 2015, which improved kprobes error handling, found here:
https://lkml.org/lkml/2015/2/26/452

ACM driver may accept data to transmit while system is not fully
resumed. In this case ACM driver buffers data and prepare URBs
on usb anchor list.
There is a little chance that two tasks put a char and initiate
acm_tty_flush_chars(). In such a case, driver will put one URB
twice on usb anchor list.
This patch also reset length of data before resue of a buffer.
This not only prevent sending rubbish, but also lower risc of race.
Without this patch we hit following kernel panic in one of our
stabilty/stress tests.

syzkaller recently triggered OOM during percpu map allocation;
while there is work in progress by Dennis Zhou to add __GFP_NORETRY
semantics for percpu allocator under pressure, there seems also a
missing bpf_map_precharge_memlock() check in array map allocation.
Given today the actual bpf_map_charge_memlock() happens after the
find_and_alloc_map() in syscall path, the bpf_map_precharge_memlock()
is there to bail out early before we go and do the map setup work
when we find that we hit the limits anyway. Therefore add this for
array map as well.

Pull power management fixes from Rafael Wysocki:
"These fix a recently introduced build issue related to cpuidle and two
bugs in the PM core, update cpuidle documentation and clean up memory
allocations in the operating performance points (OPP) framework.
Specifics:
- Fix a recently introduced build issue related to cpuidle by
covering all of the relevant combinations of Kconfig options
in its header (Rafael Wysocki).
- Add missing invocation of pm_runtime_drop_link() to the
!CONFIG_SRCU variant of __device_link_del() (Lukas Wunner).
- Fix unbalanced IRQ enable in the wakeup interrupts framework
(Tony Lindgren).
- Update cpuidle sysfs ABI documentation (Aishwarya Pant).
- Use GFP_KERNEL instead of GFP_ATOMIC for allocating memory
in dev_pm_opp_init_cpufreq_table() (Jia-Ju Bai)"

This ensures that we return the right structures back to userspace.
Otherwise, it looks like the reserved fields in the response structures
in userspace might have uninitialized data in them.

just a missed remnant from an earlier version of the function before
this locking was moved into uverbs_free_xrcd.

The command number is not bounds checked against the command mask before it
is shifted, resulting in an ubsan hit. This does not cause malfunction since
the command number is eventually bounds checked, but we can make this ubsan
clean by moving the bounds check to before the mask check.

This is really being used as an assert that the expected usecnt
is being held and implicitly that the usecnt is valid. Rename it to
assert_uverbs_usecnt and tighten the checks to only accept valid
values of usecnt (eg 0 and < -1 are invalid).
The tigher checkes make the assertion cover more cases and is more
likely to find bugs via syzkaller/etc.
