[ Upstream commit 3a36273e5a ]
If no free IBI slot is available, svc_i3c_master_handle_ibi returns
immediately. This causes the STOP condition to be missed because the
EmitStop request is sent when the transfer is not complete. To resolve
this, svc_i3c_master_handle_ibi must wait for the transfer to complete
before returning.

[ Upstream commit 9d4f219807 ]
In `i3c_master_register`, a possible refcount inconsistency has been
identified, causing possible resource leak.
Function `of_node_get` increases the refcount of `parent->of_node`. If
function `i3c_bus_init` fails, the function returns immediately without
a corresponding decrease, resulting in an inconsistent refcounter.
Move call i3c_bus_init() after device_initialize() to let callback
i3c_masterdev_release() release of_node.

The I2C pins for some of the instances on J784S4/J742S2/AM69 are
configured as PIN_INPUT_PULLUP while these pins are open-drain type and
do not support internal pull-ups [0][1][2]. The pullup configuration
bits in the corresponding padconfig registers are reserved and any
writes to them have no effect and readback checks on those bits fail.
Update the pinmux settings to use PIN_INPUT instead of PIN_INPUT_PULLUP

when ivpu_gem_bo_free() removes the BO from the BOs list before it

[ Upstream commit ced37e9cea ]
When triggering a stack dump via sysrq (echo t > /proc/sysrq-trigger),
KASAN may report false-positive out-of-bounds access:
BUG: KASAN: out-of-bounds in __show_regs+0x4b/0x340
Call Trace:
dump_stack_lvl
print_address_description.constprop.0
print_report
__show_regs
show_trace_log_lvl

sysrq_handle_showstate
__handle_sysrq
write_sysrq_trigger
proc_reg_write
vfs_write
ksys_write
do_syscall_64
entry_SYSCALL_64_after_hwframe
The issue occurs as follows:
Task A (walk other tasks' stacks) Task B (running)
1. echo t > /proc/sysrq-trigger
show_trace_log_lvl
regs = unwind_get_entry_regs()
show_regs_if_on_stack(regs)
2. The stack value pointed by
`regs` keeps changing, and
so are the tags in its
KASAN shadow region.
__show_regs(regs)
regs->ax, regs->bx, ...
3. hit KASAN redzones, OOB
When task A walks task B's stack without suspending it, the continuous changes
in task B's stack (and corresponding KASAN shadow tags) may cause task A to
hit KASAN redzones when accessing obsolete values on the stack, resulting in
false positive reports.
Simply stopping the task before unwinding is not a viable fix, as it would
alter the state intended to inspect. This is especially true for diagnosing
misbehaving tasks (e.g., in a hard lockup), where stopping might fail or hide
the root cause by changing the call stack.
Therefore, fix this by disabling KASAN checks during asynchronous stack
unwinding, which is identified when the unwinding task does not match the
current task (task != current).

there is a path where the assumption is not true.

Relocate the wake-gpios and perst-gpios properties from the pcie0
controller node to the pcieport0 node. These GPIOs are associated with
the PCIe root port and should reside under the pcieport0 node.
Also rename perst-gpios to reset-gpios to match the expected property name
in the PCIe port node.

[ Upstream commit c2703c9016 ]
The UFS device is ovbiously dma coherent like the other IOMMU devices
like usb, mmc, ... let's fix this by adding the flag.
To be sure an extensive test has been performed to be sure it's
safe, as downstream uses this flag for UFS as well.
As an experiment, I checked how the dma-coherent could impact
the UFS bandwidth, and it happens the max bandwidth on cached
write is slighly highter (up to 10%) while using less cpu time
since cache sync/flush is skipped.

[ Upstream commit 2602949b22 ]
I recently got occasional build failures at -Os or -Oz that would always
involve waitpid(), where the assembler would complain about this:
init.s: Error: .size expression for waitpid.constprop.0 does not evaluate to a constant
And without -fno-asynchronous-unwind-tables it could also spit such
errors:
init.s:836: Error: CFI instruction used without previous .cfi_startproc
init.s:838: Error: .cfi_endproc without corresponding .cfi_startproc
init.s: Error: open CFI at the end of file; missing .cfi_endproc directive
A trimmed down reproducer is as simple as this:
int main(int argc, char **argv)
{
int ret, status;
if (argc == 0)
ret = waitpid(-1, &status, 0);
else
ret = waitpid(-1, &status, 0);
return status;
}
It produces the following asm code on x86_64:
.text
.section .text.nolibc_memmove_memcpy
.weak memmove
.weak memcpy
memmove:
memcpy:
movq %rdx, %rcx
(...)
retq
.section .text.nolibc_memset
.weak memset
memset:
xchgl %eax, %esi
movq %rdx, %rcx
pushq %rdi
rep stosb
popq %rax
retq
.type waitpid.constprop.0.isra.0, @function
waitpid.constprop.0.isra.0:
subq $8, %rsp
(...)
jmp *.L5(,%rax,8)
.section .rodata
.align 8
.align 4
.L5:
.quad .L10
(...)
.quad .L4
.text
.L10:
(...)
.cfi_def_cfa_offset 8
ret
.cfi_endproc
.LFE273:
.size waitpid.constprop.0.isra.0, .-waitpid.constprop.0.isra.0
It's a bit dense, but here's the explanation: the compiler has emitted a
".text" statement because it knows it's working in the .text section.
Then, our hand-written asm code for the mem* functions forced the section
to .text.something without the compiler knowing about it, so it thinks
the code is still being emitted for .text. As such, without any .section
statement, the waitpid.constprop.0.isra.0 label is in fact placed in the
previously created section, here .text.nolibc_memset.
The waitpid() function involves a switch/case statement that can be
turned to a jump table, which is what the compiler does with the .rodata
section, and after that it restores .text, which is no longer the
previous .text.nolibc_memset section. Then the CFI statements cross a
section, so does the .size calculation, which explains the error.
While a first approach consisting in placing an explicit ".text" at the
end of these functions was verified to work, it's still unreliable as
it depends on what the compiler remembers having emitted previously. A
better approach is to replace the ".section" with ".pushsection", and
place a ".popsection" at the end, so that these code blocks are agnostic
to where they're placed relative to other blocks.
