commit ef3e40a7ea8dbe2abd0a345032cd7d5023b9684f upstream.
When using the PtrAuth feature in a guest, we need to save the host's
keys before allowing the guest to program them. For that, we dump
them in a per-CPU data structure (the so called host context).
But both call sites that do this are in preemptible context,
which may end up in disaster should the vcpu thread get preempted
before reentering the guest.
Instead, save the keys eagerly on each vcpu_load(). This has an
increased overhead, but is at least safe.

commit 0370964dd3ff7d3d406f292cb443a927952cbd05 upstream.
On a VHE system, the EL1 state is left in the CPU most of the time,
and only syncronized back to memory when vcpu_put() is called (most
of the time on preemption).
Which means that when injecting an exception, we'd better have a way
to either:
(1) write directly to the EL1 sysregs
(2) synchronize the state back to memory, and do the changes there
For an AArch64, we already do (1), so we are safe. Unfortunately,
doing the same thing for AArch32 would be pretty invasive. Instead,
we can easily implement (2) by calling the put/load architectural
backends, and keep preemption disabled. We can then reload the
state back into EL1.

[ Upstream commit 3866f217aaa81bf7165c7f27362eee5d7919c496 ]
call_undef_hook() in traps.c applies the same instr_mask for both 16-bit
and 32-bit thumb instructions. If instr_mask then is only 16 bits wide
(0xffff as opposed to 0xffffffff), the first half-word of 32-bit thumb
instructions will be masked out. This makes the function match 32-bit
thumb instructions where the second half-word is equal to instr_val,
regardless of the first half-word.
The result in this case is that all undefined 32-bit thumb instructions
with the second half-word equal to 0xde01 (udf #1) work as breakpoints
and will raise a SIGTRAP instead of a SIGILL, instead of just the one
intended 16-bit instruction. An example of such an instruction is
0xeaa0de01, which is unallocated according to Arm ARM and should raise a
SIGILL, but instead raises a SIGTRAP.
This patch fixes the issue by setting all the bits in instr_mask, which
will still match the intended 16-bit thumb instruction (where the
upper half is always 0), but not any 32-bit thumb instructions.

[ Upstream commit 24cf6eef79a7e85cfd2ef9dea52f769c9192fc6e ]
"usb-nop-xceiv" is good enough if we don't lose the configuration done
by the firmware, but we'd really prefer a real driver.
Unfortunately, the PHY core is odd in that when the node is compatible
with "usb-nop-xceiv", it ignores the other compatible strings. Let's
just remove it.

[ Upstream commit 665e7c73a7724a393b4ec92d1ae1e029925ef2b7 ]
Avoid LDB and IPU DI clocks both using the same parent. LDB requires
pasthrough clock to avoid breaking timing while IPU DI does not.
Force IPU DI clocks to use IMX6QDL_CLK_PLL2_PFD0_352M as parent
and LDB to use IMX6QDL_CLK_PLL5_VIDEO_DIV.
This fixes an issue where attempting atomic modeset while using
HDMI and display port at the same time causes LDB clock programming
to destroy the programming of HDMI that was done during the same
modeset.

[ Upstream commit 71f8af1110101facfad68989ff91f88f8e2c3e22 ]
Tomas Paukrt reports that his SAM9X60 based system (ARM926, ARMv5TJ)
fails to fix up alignment faults, eventually resulting in a kernel
oops.
The problem occurs when using CONFIG_CPU_USE_DOMAINS with commit
e6978e4bf181 ("ARM: save and reset the address limit when entering an
exception"). This is because the address limit is set back to
TASK_SIZE on exception entry, and, although it is restored on exception
exit, the domain register is not.
Hence, this sequence can occur:
interrupt
pt_regs->addr_limit = addr_limit // USER_DS
addr_limit = USER_DS
alignment exception
__probe_kernel_read()
old_fs = get_fs() // USER_DS
set_fs(KERNEL_DS)
addr_limit = KERNEL_DS
dacr.kernel = DOMAIN_MANAGER
interrupt
pt_regs->addr_limit = addr_limit // KERNEL_DS
addr_limit = USER_DS
alignment exception
__probe_kernel_read()
old_fs = get_fs() // USER_DS
set_fs(KERNEL_DS)
addr_limit = KERNEL_DS
dacr.kernel = DOMAIN_MANAGER
...
set_fs(old_fs)
addr_limit = USER_DS
dacr.kernel = DOMAIN_CLIENT
...
addr_limit = pt_regs->addr_limit // KERNEL_DS
interrupt returns
At this point, addr_limit is correctly restored to KERNEL_DS for
__probe_kernel_read() to continue execution, but dacr.kernel is not,
it has been reset by the set_fs(old_fs) to DOMAIN_CLIENT.
This would not have happened prior to the mentioned commit, because
addr_limit would remain KERNEL_DS, so get_fs() would have returned
KERNEL_DS, and so would correctly nest.
This commit fixes the problem by also saving the DACR on exception
entry if either CONFIG_CPU_SW_DOMAIN_PAN or CONFIG_CPU_USE_DOMAINS are
enabled, and resetting the DACR appropriately on exception entry to
match addr_limit and PAN settings.

[ Upstream commit 738b150ecefbffb6e55cfa8a3b66a844f777d8fb ]
Looks like using the UART CTS pin does not always trigger for a wake-up
when the SoC is idle.
This is probably because the modem first uses gpio_149 to signal the SoC
that data will be sent, and the CTS will only get used later when the
data transfer is starting.
Let's fix the issue by configuring the gpio_149 pad as the wakeirq for
UART. We have gpio_149 managed by the USB PHY for powering up the right
USB mode, and after that, the gpio gets recycled as the modem wake-up
pin. If needeed, the USB PHY can also later on be configured to use
gpio_149 pad as the wakeirq as a shared irq.
Let's also configure the missing properties for uart-has-rtscts and
current-speed for the modem port while at it. We already configure the
hardware flow control pins with uart1_pins pinctrl setting.

commit 0ebeea8ca8a4d1d453ad299aef0507dab04f6e8d upstream.
Given the legacy bpf_probe_read{,str}() BPF helpers are broken on archs
with overlapping address ranges, we should really take the next step to
disable them from BPF use there.
To generally fix the situation, we've recently added new helper variants
bpf_probe_read_{user,kernel}() and bpf_probe_read_{user,kernel}_str().
For details on them, see 6ae08ae3dea2 ("bpf: Add probe_read_{user, kernel}
and probe_read_{user,kernel}_str helpers").
Given bpf_probe_read{,str}() have been around for ~5 years by now, there
are plenty of users at least on x86 still relying on them today, so we
cannot remove them entirely w/o breaking the BPF tracing ecosystem.
However, their use should be restricted to archs with non-overlapping
address ranges where they are working in their current form. Therefore,
move this behind a CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE and
have x86, arm64, arm select it (other archs supporting it can follow-up
on it as well).
For the remaining archs, they can workaround easily by relying on the
feature probe from bpftool which spills out defines that can be used out
of BPF C code to implement the drop-in replacement for old/new kernels
via: bpftool feature probe macro

[ Upstream commit 8101b5a1531f3390b3a69fa7934c70a8fd6566ad ]
Stephen reported the following build warning on a ARM multi_v7_defconfig
build with GCC 9.2.1:
kernel/futex.c: In function 'do_futex':
kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized]
1676 | return oldval == cmparg;
| ~~~~~~~^~~~~~~~~
kernel/futex.c:1652:6: note: 'oldval' was declared here
1652 | int oldval, ret;
| ^~~~~~
introduced by commit a08971e9488d ("futex: arch_futex_atomic_op_inuser()
calling conventions change").
While that change should not make any difference it confuses GCC which
fails to work out that oldval is not referenced when the return value is
not zero.
GCC fails to properly analyze arch_futex_atomic_op_inuser(). It's not the
early return, the issue is with the assembly macros. GCC fails to detect
that those either set 'ret' to 0 and set oldval or set 'ret' to -EFAULT
which makes oldval uninteresting. The store to the callsite supplied oldval
pointer is conditional on ret == 0.
The straight forward way to solve this is to make the store unconditional.
Aside of addressing the build warning this makes sense anyway because it
removes the conditional from the fastpath. In the error case the stored
value is uninteresting and the extra store does not matter at all.

commit e47cb97f153193d4b41ca8d48127da14513d54c7 upstream.
The Clock Pulse Generator (CPG) device node lacks the extal2 clock.
This may lead to a failure registering the "r" clock, or to a wrong
parent for the "usb24s" clock, depending on MD_CK2 pin configuration and
boot loader CPG_USBCKCR register configuration.
This went unnoticed, as this does not affect the single upstream board
configuration, which relies on the first clock input only.

commit 90d4d3f4ea45370d482fa609dbae4d2281b4074f upstream.
Even though commit cfb5d65f2595 ("ARM: dts: dra7: Add bus_dma_limit
for L3 bus") added bus_dma_limit for L3 bus, the PCIe controller
gets incorrect value of bus_dma_limit.
Fix it by adding empty dma-ranges property to axi@0 and axi@1
(parent device tree node of PCIe controller).

commit 706024a52c614b478b63f7728d202532ce6591a9 upstream.
The initial Zinc patchset, after some mailing list discussion, contained
code to ensure that kernel_fpu_enable would not be kept on for more than
a 4k chunk, since it disables preemption. The choice of 4k isn't totally
scientific, but it's not a bad guess either, and it's what's used in
both the x86 poly1305, blake2s, and nhpoly1305 code already (in the form
of PAGE_SIZE, which this commit corrects to be explicitly 4k for the
former two).
Ard did some back of the envelope calculations and found that
at 5 cycles/byte (overestimate) on a 1ghz processor (pretty slow), 4k
means we have a maximum preemption disabling of 20us, which Sebastian
confirmed was probably a good limit.
Unfortunately the chunking appears to have been left out of the final
patchset that added the glue code. So, this commit adds it back in.

commit a9a8ba90fa5857c2c8a0e32eef2159cec717da11 upstream.
Rather than chunking via PAGE_SIZE, this commit changes the arch

maximum acceptable latency don't suddenly become invalid on platforms

commit be08d278eb09210fefbad4c9b27d7843f1c096b2 upstream.
With the introduction of 55c7c0621078 ("ARM: dts: bcm283x: Fix vc4's
firmware bus DMA limitations") the firmware bus has to comply with
/soc's DMA limitations. Ultimately linking both buses to a same
dma-ranges property. The patch (and author) missed the fact that a bus'
#address-cells and #size-cells properties are not inherited, but set to
a fixed value which, in this case, doesn't match /soc's. This, although
not breaking Linux's DMA mapping functionality, generates ugly dtc
warnings.
Fix the issue by adding the correct address and size cells properties
under the firmware bus.

Fix this by having v7_cpu_resume() compiled only when cpu_resume() it

inadvertently using a stub and introducing a regression to the bug the

commit 4141f1a40fc0789f6fd4330e171e1edf155426aa upstream.
In order to wake from suspend by ethernet magic packets the GPC
must be used as intc does not have wakeup functionality.
But the FEC DT node currently uses interrupt-extended,
specificying intc, thus breaking WoL.
This problem is probably fallout from the stacked domain conversion
as intc used to chain to GPC.
So replace "interrupts-extended" by "interrupts" to use the default
parent which is GPC.

commit bb9562cf5c67813034c96afb50bd21130a504441 upstream.
The current arm BPF JIT does not correctly compile RSH or ARSH when the
immediate shift amount is 0. This causes the "rsh64 by 0 imm" and "arsh64
by 0 imm" BPF selftests to hang the kernel by reaching an instruction
the verifier determines to be unreachable.
The root cause is in how immediate right shifts are encoded on arm.
For LSR and ASR (logical and arithmetic right shift), a bit-pattern
of 00000 in the immediate encodes a shift amount of 32. When the BPF
immediate is 0, the generated code shifts by 32 instead of the expected
behavior (a no-op).
This patch fixes the bugs by adding an additional check if the BPF
immediate is 0. After the change, the above mentioned BPF selftests pass.

commit 4178417cc5359c329790a4a8f4a6604612338cca upstream.
This patch fixes an incorrect check in how immediate memory offsets are
computed for BPF_DW on arm.
For BPF_LDX/ST/STX + BPF_DW, the 32-bit arm JIT breaks down an 8-byte
access into two separate 4-byte accesses using off+0 and off+4. If off
fits in imm12, the JIT emits a ldr/str instruction with the immediate
and avoids the use of a temporary register. While the current check off
<= 0xfff ensures that the first immediate off+0 doesn't overflow imm12,
it's not sufficient for the second immediate off+4, which may cause the
second access of BPF_DW to read/write the wrong address.
This patch fixes the problem by changing the check to
off <= 0xfff - 4 for BPF_DW, ensuring off+4 will never overflow.
A side effect of simplifying the check is that it now allows using
negative immediate offsets in ldr/str. This means that small negative
offsets can also avoid the use of a temporary register.
This patch introduces no new failures in test_verifier or test_bpf.c.

Pull ARM DT and driver fixes from Arnd Bergmann:
"For the devicetree files, there are a total of 20 patches, almost
entirely for 32-bit machines:
- The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
both for correctness and for style that are addressed in separate
patches. This causes most of the changed lines of the DT updates
this time.
- More Allwinner updates fixing the identification of the security
system on sun8i/A33, a recent regression of the A83t ethernet, and
a few board specific issues on the TBS-A711 macine.
- Several bug fixes for OMAP dts files, most notably fixing the
timings for the NAND flash on the Nokia N900 that regressed a while
ago after the move to configuring them from DT. Some other OMAPs
now set the correct dma limits on the L3 bus, and a regression fix
addresses lost Ethernet on dm814x
- One incorrect setting in the newly added Raspberry Pi Zero W that
may cause issues with the SD card controller.
- A missing property on the bcm2835 firmware node caused incorrect
DMA settings.
- An old bug on the oxnas platform causing spurious interrupts is
finally addressed.
- A regression on the Exynos Midas board broke the OLED panel power
supply.
- The i.MX6 phycore SoM specified the wrong voltage for the SoC, this
is now set to the values from the datasheet.
- Some 64-bit machines use a deprecated string to identify the PSCI
firmware.
There are also several small code fixes addressing mostly serious
issues:
- Fix the sunxi rsb bus access to no longer return incorrect data
when mixing 8 and 16 bit I/O.
- Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
quirk in the ti-sysc driver
- Fix a NULL pointer access from a race in the fsl dpio driver
- Fix a v5.5 regression in the exynos-chipid driver that caused an
invalid error code probing the device on non-exynos platforms
- Fix an out-of-bounds access in the AMD TEE driver"

Commit d4ec0cb05064 ("ARM: dts: exynos: Add support for the
touch-sensitive buttons on Midas family") added a new fixed regulator
("voltage-regulator-6") to base "midas" .dtsi, but it didn't update the
clients of that .dtsi, which define their own fixed regulators starting
from the "voltage-regulator-6". This results in aliasing of the regulator
dt nodes and breaks operation of OLED panel due to lack of power supply.
Fix this by increasing the numbers in the fixed regulator names for those
boards.
