Two locking fixes in the core/ttm area, a couple of small driver fixes

each, mostly for smaller things, though the msm has a DSI fix for a

Olivier Langlois has been struggling with coredumps being incompletely written in
processes using io_uring.
Olivier Langlois <olivier@trillion01.com> writes:

The coredump code deliberately supports being interrupted by SIGKILL,
and depends upon prepare_signal to filter out all other signals. Now
that signal_pending includes wake ups for TIF_NOTIFY_SIGNAL this hack
in dump_emitted by the coredump code no longer works.
Make the coredump code more robust by explicitly testing for all of
the wakeup conditions the coredump code supports. This prevents
new wakeup conditions from breaking the coredump code, as well
as fixing the current issue.
The filesystem code that the coredump code uses already limits
itself to only aborting on fatal_signal_pending. So it should
not develop surprising wake-up reasons either.
v2: Don't remove the now unnecessary code in prepare_signal.

TPS23861 has a configuration bit for setting of the
current shunt value used on the board.
Its bit 0 of the General Mask 1 register.
According to the datasheet bit values are:
0 for 255 mOhm (Default)
1 for 250 mOhm
So, configure the bit before registering the hwmon
device according to the value passed in the DTS or
default one if none is passed.
This caused potentially reading slightly skewed values
due to max current value being 1.02A when 250mOhm shunt
is used instead of 1.0A when 255mOhm is used.

The timer instance per queue is exclusive, and snd_seq_timer_open()
should have managed the concurrent accesses. It looks as if it's
checking the already existing timer instance at the beginning, but
it's not right, because there is no protection, hence any later
concurrent call of snd_seq_timer_open() may override the timer
instance easily. This may result in UAF, as the leftover timer
instance can keep running while the queue itself gets closed, as
spotted by syzkaller recently.
For avoiding the race, add a proper check at the assignment of
tmr->timeri again, and return -EBUSY if it's been already registered.

instead of 0 when the clk was registered with the clk framework.
After commit 001d8dc338 ("drm/msm/dsi: remove temp data from global
pll structure") we use a hardcoded value for the parent clk frequency,
i.e. VCO_REF_CLK_RATE, and we also hardcode the value for FRAC_BITS,
instead of getting it from the config structure. This combination of
changes to the recalc function allows us to properly calculate the
frequency of the PLL regardless of whether or not the PLL has been
clk_prepare()d or clk_set_rate()d. That's a good improvement.
Unfortunately, this means that now we won't call down into the PLL clk
driver when we call clk_set_rate() because the frequency calculated in
the framework matches the frequency that is set in hardware. If the rate
is the same as what we want it should be OK to not call the set_rate PLL
op. The real problem is that the prepare op in this driver uses a
private struct member to stash away the vco frequency so that it can
call the set_rate op directly during prepare. Once the set_rate op is
never called because recalc_rate told us the rate is the same, we don't
set this private struct member before the prepare op runs, so we try to
call the set_rate function directly with a frequency of 0. This
effectively kills the PLL and configures it for a rate that won't work.
Calling set_rate from prepare is really quite bad and will confuse any
downstream clks about what the rate actually is of their parent. Fixing
that will be a rather large change though so we leave that to later.
For now, let's stash away the rate we calculate during recalc so that
the prepare op knows what frequency to set, instead of 0. This way
things keep working and the display can enable the PLL properly. In the
future, we should remove that code from the prepare op so that it
doesn't even try to call the set rate function.

The function init_cq_frag_buf() can be called to initialize the current CQ
fragments buffer cq->buf, or the temporary cq->resize_buf that is filled
during CQ resize operation.
However, the offending commit started to use function get_cqe() for
getting the CQEs, the issue with this change is that get_cqe() always
returns CQEs from cq->buf, which leads us to initialize the wrong buffer,
and in case of enlarging the CQ we try to access elements beyond the size
of the current cq->buf and eventually hit a kernel panic.

This patch eliminates the following smatch warning:
drivers/gpu/drm/drm_auth.c:320 drm_master_release() warn: unlocked access 'master' (line 318) expected lock '&dev->master_mutex'
The 'file_priv->master' field should be protected by the mutex lock to
'&dev->master_mutex'. This is because other processes can concurrently
modify this field and free the current 'file_priv->master'
pointer. This could result in a use-after-free error when 'master' is
dereferenced in subsequent function calls to
'drm_legacy_lock_master_cleanup()' or to 'drm_lease_revoke()'.
An example of a scenario that would produce this error can be seen
from a similar bug in 'drm_getunique()' that was reported by Syzbot:
https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803
In the Syzbot report, another process concurrently acquired the
device's master mutex in 'drm_setmaster_ioctl()', then overwrote
'fpriv->master' in 'drm_new_set_master()'. The old value of
'fpriv->master' was subsequently freed before the mutex was unlocked.

Commit 719e1f561a ("ACPI: Execute platform _OSC also with query bit
clear") makes acpi_bus_osc_negotiate_platform_control() not only query
the platforms capabilities but it also commits the result back to the
firmware to report which capabilities are supported by the OS back to
the firmware
On certain systems the BIOS loads SSDT tables dynamically based on the
capabilities the OS claims to support. However, on these systems the
_OSC actually clears some of the bits (under certain conditions) so what
happens is that now when we call the _OSC twice the second time we pass
the cleared values and that results errors like below to appear on the
system log:
ACPI BIOS Error (bug): Could not resolve symbol [\_PR.PR00._CPC], AE_NOT_FOUND (20210105/psargs-330)
ACPI Error: Aborting method \_PR.PR01._CPC due to previous error (AE_NOT_FOUND) (20210105/psparse-529)
In addition the ACPI 6.4 spec says following [1]:
If the OS declares support of a feature in the Support Field in one
call to _OSC, then it must preserve the set state of that bit
(declaring support for that feature) in all subsequent calls.
Based on the above we can fix the issue by passing the same set of
capabilities to the platform wide _OSC in both calls regardless of the
query flag.
While there drop the context.ret.length checks which were wrong to begin
with (as the length is number of bytes not elements). This is already
checked in acpi_run_osc() that also returns an error in that case.
Includes fixes by Hans de Goede.

The calclulation of how many bytes we stuff into the
DSI pipeline for video mode panels is off by three
orders of magnitude because we did not account for the
fact that the DRM mode clock is in kilohertz rather
than hertz.
This used to be:
drm_mode_vrefresh(mode) * mode->htotal * mode->vtotal
which would become for example for s6e63m0:
60 x 514 x 831 = 25628040 Hz, but mode->clock is
25628 as it is in kHz.
This affects only the Samsung GT-I8190 "Golden" phone
right now since it is the only MCDE device with a video
mode display.
Curiously some specimen work with this code and wild
settings in the EOL and empty packets at the end of the
display, but I have noticed an eeire flicker until now.
Others were not so lucky and got black screens.

KVM's mechanism for accessing guest memory translates a guest physical
address (gpa) to a host virtual address using the right-shifted gpa
(also known as gfn) and a struct kvm_memory_slot. The translation is
performed in __gfn_to_hva_memslot using the following formula:
hva = slot->userspace_addr + (gfn - slot->base_gfn) * PAGE_SIZE
It is expected that gfn falls within the boundaries of the guest's
physical memory. However, a guest can access invalid physical addresses
in such a way that the gfn is invalid.
__gfn_to_hva_memslot is called from kvm_vcpu_gfn_to_hva_prot, which first
retrieves a memslot through __gfn_to_memslot. While __gfn_to_memslot
does check that the gfn falls within the boundaries of the guest's
physical memory or not, a CPU can speculate the result of the check and
continue execution speculatively using an illegal gfn. The speculation
can result in calculating an out-of-bounds hva. If the resulting host
virtual address is used to load another guest physical address, this
is effectively a Spectre gadget consisting of two consecutive reads,
the second of which is data dependent on the first.
Right now it's not clear if there are any cases in which this is
exploitable. One interesting case was reported by the original author
of this patch, and involves visiting guest page tables on x86. Right
now these are not vulnerable because the hva read goes through get_user(),
which contains an LFENCE speculation barrier. However, there are
patches in progress for x86 uaccess.h to mask kernel addresses instead of
using LFENCE; once these land, a guest could use speculation to read
from the VMM's ring 3 address space. Other architectures such as ARM
already use the address masking method, and would be susceptible to
this same kind of data-dependent access gadgets. Therefore, this patch
proactively protects from these attacks by masking out-of-bounds gfns
in __gfn_to_hva_memslot, which blocks speculation of invalid hvas.
Sean Christopherson noted that this patch does not cover
kvm_read_guest_offset_cached. This however is limited to a few bytes
past the end of the cache, and therefore it is unlikely to be useful in

When using shadow paging, unload the guest MMU when emulating a guest TLB
flush to ensure all roots are synchronized. From the guest's perspective,
flushing the TLB ensures any and all modifications to its PTEs will be
recognized by the CPU.
Note, unloading the MMU is overkill, but is done to mirror KVM's existing
handling of INVPCID(all) and ensure the bug is squashed. Future cleanup
can be done to more precisely synchronize roots when servicing a guest
TLB flush.
If TDP is enabled, synchronizing the MMU is unnecessary even if nested
TDP is in play, as a "legacy" TLB flush from L1 does not invalidate L1's
TDP mappings. For EPT, an explicit INVEPT is required to invalidate
guest-physical mappings; for NPT, guest mappings are always tagged with
an ASID and thus can only be invalidated via the VMCB's ASID control.
This bug has existed since the introduction of KVM_VCPU_FLUSH_TLB.
It was only recently exposed after Linux guests stopped flushing the
local CPU's TLB prior to flushing remote TLBs (see commit 4ce94eabac,
"x86/mm/tlb: Flush remote and local TLBs concurrently"), but is also
visible in Windows 10 guests.

Allow creating FDB steering rules only when in switchdev mode.
The only software model where a userspace application can manipulate
FDB entries is when it manages the eswitch. This is only possible in
switchdev mode where we expose a single RDMA device with representors
for all the vports that are connected to the eswitch.

Update CP_PROTECT register programming based on downstream.
A6XX_PROTECT_RW is renamed to A6XX_PROTECT_NORDWR to make things aligned
and also be more clear about what it does.
Note that this required switching to use the CP_ALWAYS_ON_COUNTER as the
GMU counter is not accessible from the cmdstream. Which also means
using the CPU counter for the msm_gpu_submit_flush() tracepoint (as
catapult depends on being able to compare this to the start/end values
captured in cmdstream). This may need to be revisited when IFPC is
enabled.
Also, compared to downstream, this opens up CP_PERFCTR_CP_SEL as the
userspace performance tooling (fdperf and pps-producer) expect to be
able to configure the CP counters.

I met a gpu addr bug recently and the kernel log
tells me the pc is memcpy/memset and link register is
radeon_uvd_resume.
As we know, in some architectures, optimized memcpy/memset
may not work well on device memory. Trival memcpy_toio/memset_io
can fix this problem.
BTW, amdgpu has already done it in:
commit ba0b2275a6 ("drm/amdgpu: use memcpy_to/fromio for UVD fw upload"),
that's why it has no this issue on the same gpu and platform.

Use the __string() machinery provided by the tracing subystem to make a
copy of the string literals consumed by the "nested VM-Enter failed"
tracepoint. A complete copy is necessary to ensure that the tracepoint
can't outlive the data/memory it consumes and deference stale memory.
Because the tracepoint itself is defined by kvm, if kvm-intel and/or
kvm-amd are built as modules, the memory holding the string literals
defined by the vendor modules will be freed when the module is unloaded,
whereas the tracepoint and its data in the ring buffer will live until
kvm is unloaded (or "indefinitely" if kvm is built-in).
This bug has existed since the tracepoint was added, but was recently
exposed by a new check in tracing to detect exactly this type of bug.

xen-netback: take a reference to the RX task thread
Until commit 39fe2fc966 ("selftests: kvm: make allocation of extra
memory take effect", 2021-05-27), parameter extra_mem_pages was used
only to calculate the page table size for all the memory chunks,
because real memory allocation happened with calls of
vm_userspace_mem_region_add() after vm_create_default().
Commit 39fe2fc966 however changed the meaning of extra_mem_pages to
the size of memory slot 0. This makes the memory allocation more
flexible, but makes it harder to account for the number of
pages needed for the page tables. For example, memslot_perf_test
has a small amount of memory in slot 0 but a lot in other slots,
and adding that memory twice (both in slot 0 and with later
calls to vm_userspace_mem_region_add()) causes an error that
was fixed in commit 000ac42953 ("selftests: kvm: fix overlapping
addresses in memslot_perf_test", 2021-05-29)
Since both uses are sensible, add a new parameter slot0_mem_pages
to vm_create_with_vcpus() and some comments to clarify the meaning of
slot0_mem_pages and extra_mem_pages. With this change,
memslot_perf_test can go back to passing the number of memory
pages as extra_mem_pages.
