commit ff0c129d3b5ecb3df7c8f5e2236582bf745b6c5f upstream.

bio_sectors() returns the value in the units of 512-byte sectors (no
matter what the real sector size of the device).  dm-crypt multiplies
bio_sectors() by on_disk_tag_size to calculate the space allocated for
integrity tags.  If dm-crypt is running with sector size larger than
512b, it allocates more data than is needed.

Device Mapper trims the extra space when passing the bio to
dm-integrity, so this bug didn't result in any visible misbehavior.
But it must be fixed to avoid wasteful memory allocation for the block
integrity payload.

dump_thread32() in aout_core_dump() does not clear the user32 structure
allocated on the stack as the first thing on function entry.

As a result, the dump.u_comm, dump.u_ar0 and dump.signal which get
assigned before the clearing, get overwritten.

Rename that function to fill_dump() to make it clear what it does and
call it first thing.

commit dfcc34c99f3ebc16b787b118763bf9cb6b1efc7a upstream.

sync_request_write no longer submits writes to a Faulty device. This has
the unfortunate side effect that bitmap bits can be incorrectly cleared
if a recovery is interrupted (previously, end_sync_write would have
prevented this). This means the next recovery may not copy everything
it should, potentially corrupting data.

Add a function for doing the proper md_bitmap_end_sync, called from
end_sync_write and the Faulty case in sync_request_write.

commit cf43a757fd49442bc38f76088b70c2299eed2c2f upstream.

In the middle of do_exit() there is there is a call
"ptrace_event(PTRACE_EVENT_EXIT, code);" That call places the process
in TACKED_TRACED aka "(TASK_WAKEKILL | __TASK_TRACED)" and waits for
for the debugger to release the task or SIGKILL to be delivered.

Skipping past dequeue_signal when we know a fatal signal has already
been delivered resulted in SIGKILL remaining pending and
TIF_SIGPENDING remaining set.  This in turn caused the
scheduler to not sleep in PTACE_EVENT_EXIT as it figured
a fatal signal was pending.  This also caused ptrace_freeze_traced
in ptrace_check_attach to fail because it left a per thread
SIGKILL pending which is what fatal_signal_pending tests for.

This difference in signal state caused strace to report
strace: Exit of unknown pid NNNNN ignored

Therefore update the signal handling state like dequeue_signal
would when removing a per thread SIGKILL, by removing SIGKILL
from the per thread signal mask and clearing TIF_SIGPENDING.

commit e4a056987c86f402f1286e050b1dee3f4ce7c7eb upstream.

The problem is that the default for MQ is not to gather entropy, whereas
the default for the legacy queue was always to gather it.  The original
attempt to fix entropy gathering for rotational disks under MQ added an
else branch in sd_read_block_characteristics().  Unfortunately, the entire
check isn't reached if the device has no characteristics VPD page.  Since
this page was only introduced in SBC-3 and its optional anyway, most less
expensive rotational disks don't have one, meaning they all stopped
gathering entropy when we made MQ the default.  In a wholly unrelated
change, openssl and openssh won't function until the random number
generator is initialised, meaning lots of people have been seeing large
delays before they could log into systems with default MQ kernels due to
this lack of entropy, because it now can take tens of minutes to initialise
the kernel random number generator.

The fix is to set the non-rotational and add-randomness flags
unconditionally early on in the disk initialization path, so they can be
reset only if the device actually reports being non-rotational via the VPD
page.

commit 0722069a5374b904ec1a67f91249f90e1cfae259 upstream.

When printing multiple uprobe arguments as strings the output for the
earlier arguments would also include all later string arguments.

This is best explained in an example:

Consider adding a uprobe to a function receiving two strings as
parameters which is at offset 0xa0 in strlib.so and we want to print
both parameters when the uprobe is hit (on x86_64):

$ echo 'p:func /lib/strlib.so:0xa0 +0(%di):string +0(%si):string' > \
    /sys/kernel/debug/tracing/uprobe_events

When the function is called as func("foo", "bar") and we hit the probe,
the trace file shows a line like the following:

  [...] func: (0x7f7e683706a0) arg1="foobar" arg2="bar"

Note the extra "bar" printed as part of arg1. This behaviour stacks up
for additional string arguments.

The strings are stored in a dynamically growing part of the uprobe
buffer by fetch_store_string() after copying them from userspace via
strncpy_from_user(). The return value of strncpy_from_user() is then
directly used as the required size for the string. However, this does
not take the terminating null byte into account as the documentation
for strncpy_from_user() cleary states that it "[...] returns the
length of the string (not including the trailing NUL)" even though the
null byte will be copied to the destination.

Therefore, subsequent calls to fetch_store_string() will overwrite
the terminating null byte of the most recently fetched string with
the first character of the current string, leading to the
"accumulation" of strings in earlier arguments in the output.

Fix this by incrementing the return value of strncpy_from_user() by
one if we did not hit the maximum buffer size.

commit 8f9aca0c45322a807a343fc32f95f2500f83b9ae upstream.

The older machines don't have the QCI instruction available.
With support for up to 256 crypto cards the probing of each
card has been extended to check card ids from 0 up to 255.
For machines with QCI support there is a filter limiting the
range of probed cards. The older machines (z196 and older)
don't have this filter and so since support for 256 cards is
in the driver all cards are probed. However, these machines
also require to have the card id fit into 6 bits. Exceeding
this limit results in a specification exception which happens
on every kernel startup even when there is no crypto configured
and used at all.

This fix limits the range of probed crypto cards to 64 if
there is no QCI instruction available to obey to the older
ap architecture and so fixes the specification exceptions
on z196 machines.

commit bfc913682464f45bc4d6044084e370f9048de9d5 upstream.

Eiger machine vector definition has nr_irqs 128, and working 2.6.26
boot shows SCSI getting IRQ-s 64 and 65. Current kernel boot fails
because Symbios SCSI fails to request IRQ-s and does not find the disks.
It has been broken at least since 3.18 - the earliest I could test with
my gcc-5.

The headers have moved around and possibly another order of defines has
worked in the past - but since 128 seems to be correct and used, fix
arch/alpha/include/asm/irq.h to have NR_IRQS=128 for Eiger.

This fixes 4.19-rc7 boot on my Force Flexor A264 (Eiger subarch).

commit 491af60ffb848b59e82f7c9145833222e0bf27a5 upstream.

Fix page fault handling code to fixup r16-r18 registers.
Before the patch code had off-by-two registers bug.
This bug caused overwriting of ps,pc,gp registers instead
of fixing intended r16,r17,r18 (see `struct pt_regs`).

More details:

Initially Dmitry noticed a kernel bug as a failure
on strace test suite. Test passes unmapped userspace
pointer to io_submit:

```c
    #include <err.h>
    #include <unistd.h>
    #include <sys/mman.h>
    #include <asm/unistd.h>
    int main(void)
    {
        unsigned long ctx = 0;
        if (syscall(__NR_io_setup, 1, &ctx))
            err(1, "io_setup");
        const size_t page_size = sysconf(_SC_PAGESIZE);
        const size_t size = page_size * 2;
        void *ptr = mmap(NULL, size, PROT_READ | PROT_WRITE,
                         MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);
        if (MAP_FAILED == ptr)
            err(1, "mmap(%zu)", size);
        if (munmap(ptr, size))
            err(1, "munmap");
        syscall(__NR_io_submit, ctx, 1, ptr + page_size);
        syscall(__NR_io_destroy, ctx);
        return 0;
    }
```

Running this test causes kernel to crash when handling page fault:

```

```

Here `gp` has invalid value. `gp is s overwritten by a fixup for the
following page fault handler in `io_submit` syscall handler:

```
    __se_sys_io_submit
    ...
        ldq     a1,0(t1)
        bne     t0,4280 <__se_sys_io_submit+0x180>
```

After a page fault `t0` should contain -EFALUT and `a1` is 0.
Instead `gp` was overwritten in place of `a1`.

This happens due to a off-by-two bug in `dpf_reg()` for `r16-r18`
(aka `a0-a2`).

I think the bug went unnoticed for a long time as `gp` is one
of scratch registers. Any kernel function call would re-calculate `gp`.

Dmitry tracked down the bug origin back to 2.1.32 kernel version
where trap_a{0,1,2} fields were inserted into struct pt_regs.
And even before that `dpf_reg()` contained off-by-one error.

commit a9a238e83fbb0df31c3b9b67003f8f9d1d1b6c96 upstream.

This reverts commit 172b06c3 ("mm: slowly shrink slabs with a
relatively small number of objects").

This change changes the agressiveness of shrinker reclaim, causing small
cache and low priority reclaim to greatly increase scanning pressure on
small caches.  As a result, light memory pressure has a disproportionate
affect on small caches, and causes large caches to be reclaimed much
faster than previously.

As a result, it greatly perturbs the delicate balance of the VFS caches
(dentry/inode vs file page cache) such that the inode/dentry caches are
reclaimed much, much faster than the page cache and this drives us into
several other caching imbalance related problems.

As such, this is a bad change and needs to be reverted.

[ Needs some massaging to retain the later seekless shrinker
  modifications.]

commit 3bf6b57ec2ec945e5a6edf5c202a754f1e852ecd upstream.

This reverts commit d6ebf508.

I forgot that the kernel's default lease period should never be
decreased!

After a kernel upgrade, the kernel has no way of knowing on its own what
the previous lease time was.  Unless userspace tells it otherwise, it
will assume the previous lease period was the same.

So if we decrease this value in a kernel upgrade, we end up enforcing a
grace period that's too short, and clients will fail to reclaim state in
time.  Symptoms may include EIO and log messages like "NFS:
nfs4_reclaim_open_state: Lock reclaim failed!"

There was no real justification for the lease period decrease anyway.

commit dcf6e2e38a1c7ccbc535de5e1d9b14998847499d upstream.

The kblockd workqueue is created with the WQ_MEM_RECLAIM flag set.
This generates a rescuer thread for that queue that will trigger when
the CPU is under heavy load and collect the uncompleted work.

In the case of mmc, this creates the possibility of a deadlock when
there are multiple partitions on the device as other blk-mq work is
also run on the same queue. For example:

- worker 0 claims the mmc host to work on partition 1
- worker 1 attempts to claim the host for partition 2 but has to wait
  for worker 0 to finish
- worker 0 schedules complete_work to release the host
- rescuer thread is triggered after time-out and collects the dangling
  work
- rescuer thread attempts to complete the work in order starting with
  claim host
- the task to release host is now blocked by a task to claim it and
  will never be called

The above results in multiple hung tasks that lead to failures to
mount partitions.

Handling complete_work on a separate workqueue avoids this by keeping
the work completion tasks separate from the other blk-mq work. This
allows the host to be released without getting blocked by other tasks
attempting to claim the host.

commit d6f11e7d91f2ac85f66194fe3ef8789b49901d64 upstream.

The MMC device tree bindings include properties used to signal various
signalling speed modes. Until now the sunxi driver was accepting them
without any further filtering, while the sunxi device trees were not
actually using them.

Since some of the H5 boards can not run at higher speed modes stably,
we are resorting to declaring the higher speed modes per-board.

Regardless, having boards declare modes and blindly following them,
even without proper support in the driver, is generally a bad thing.

Filter out all unsupported modes from the capabilities mask after
the device tree properties have been parsed.

The reason is that while event init code does several checks
for BTS events and prevents several unwanted config bits for
BTS event (like precise_ip), the PERF_EVENT_IOC_PERIOD allows
to create BTS event without those checks being done.

Following sequence will cause the crash:

If we create an 'almost' BTS event with precise_ip and callchains,
and it into a BTS event it will crash the perf_prepare_sample()
function because precise_ip events are expected to come
in with callchain data initialized, but that's not the
case for intel_pmu_drain_bts_buffer() caller.

Adding a check_period callback to be called before the period
is changed via PERF_EVENT_IOC_PERIOD. It will deny the change
if the event would become BTS. Plus adding also the limit_period
check as well.

commit 528871b456026e6127d95b1b2bd8e3a003dc1614 upstream.

The following commit:

  9dff0aa95a32 ("perf/core: Don't WARN() for impossible ring-buffer sizes")

results in perf recording failures with larger mmap areas:

  root@skl:/tmp# perf record -g -a
  failed to mmap with 12 (Cannot allocate memory)

The root cause is that the following condition is buggy:

	if (order_base_2(size) >= MAX_ORDER)
		goto fail;

The problem is that @size is in bytes and MAX_ORDER is in pages,
so the right test is:

	if (order_base_2(size) >= PAGE_SHIFT+MAX_ORDER)
		goto fail;

Fix it.

commit d0243693fbf6fbd48b4efb2ba7210765983b03e3 upstream.

Commit 83a86fbb ("irqchip/gic: Loudly complain about the use of
IRQ_TYPE_NONE") started warning about incorrect dts usage for irqs.
ARM GIC only supports active-high interrupts for SPI (Shared Peripheral
Interrupts), and the Palmas PMIC by default is active-low.

Palmas PMIC allows changing the interrupt polarity using register
PALMAS_POLARITY_CTRL_INT_POLARITY, but configuring sys_nirq1 with
a pull-down and setting PALMAS_POLARITY_CTRL_INT_POLARITY made the
Palmas RTC interrupts stop working. This can be easily tested with
kernel tools rtctest.c.

Turns out the SoC inverts the sys_nirq pins for GIC as they do not go
through a peripheral device but go directly to the MPUSS wakeupgen.
I've verified this by muxing the interrupt line temporarily to gpio_wk16
instead of sys_nirq1. with a gpio, the interrupt works fine both
active-low and active-high with the SoC internal pull configured and
palmas polarity configured. But as sys_nirq1, the interrupt only works
when configured ACTIVE_LOW for palmas, and ACTIVE_HIGH for GIC.

Note that there was a similar issue earlier with tegra114 and palmas
interrupt polarity that got fixed by commit df545d1c ("mfd: palmas:
Provide irq flags through DT/platform data"). However, the difference
between omap5 and tegra114 is that tegra inverts the palmas interrupt
twice, once when entering tegra PMC, and again when exiting tegra PMC
to GIC.

Let's fix the issue by adding a custom wakeupgen_irq_set_type() for
wakeupgen and invert any interrupts with wrong polarity. Let's also
warn about any non-sysnirq pins using wrong polarity. Note that we
also need to update the dts for the level as IRQ_TYPE_NONE never
has irq_set_type() called, and let's add some comments and use proper
pin nameing to avoid more confusion later on.

could deplete asid bits and overwrite kvm_sev_info's regions_list.

Multiple calls to KVM_SVM_INIT is not likely to occur with QEMU, but this
should likely be fixed anyway.

This code is serialized by kvm->lock.

The code tries to allocate a contiguous buffer with a size supplied by
the server (maxBuf). This could fail if memory is fragmented since it
results in high order allocations for commonly used server
implementations. It is also wasteful since there are probably
few locks in the usual case. Limit the buffer to be no larger than a
page to avoid memory allocation failures due to fragmentation.

When a fan is controlled via linear fallback without cstate, we
shouldn't stop polling.  Otherwise it won't be adjusted again and
keeps running at an initial crazy pace.

[ Upstream commit df209c43a0e8258e096fb722dfbdae4f0dd13fde ]

devm_kzalloc(), devm_kstrdup() and devm_kasprintf() all can
fail internal allocation and return NULL. Using any of the assigned
objects without checking is not safe. As this is early in the boot
phase and these allocations really should not fail, any failure here
is probably an indication of a more serious issue so it makes little
sense to try and rollback the previous allocated resources or try to
continue;  but rather the probe function is simply exited with -ENOMEM.

These two lines are active high, not active low. The bug was
found when we changed the kernel to respect the polarity defined
in the device tree.

Add the board level fixed regulators for 3.3V and 1.8V which is used to
power - among other things - the tlv320aic3106 codec.

Apart from removing the following warning during boot:
tlv320aic3x-codec 0-0018: Invalid supply voltage(s) AVDD: -22, DVDD: -22

With the correct voltages the driver can select correct OCMV value to
reduce pop noise.
