LoongArch: BPF: Fix unconditional bswap instructions
We can see that "bswap32: Takes an unsigned 32-bit number in either big-
or little-endian format and returns the equivalent number with the same
bit width but opposite endianness" in BPF Instruction Set Specification,
so it should clear the upper 32 bits in "case 32:" for both BPF_ALU and
BPF_ALU64.
[root@linux fedora]# echo 1 > /proc/sys/net/core/bpf_jit_enable
[root@linux fedora]# modprobe test_bpf
Before:
test_bpf: #313 BSWAP 32: 0x0123456789abcdef -> 0xefcdab89 jited:1 ret 1460850314 != -271733879 (0x5712ce8a != 0xefcdab89)FAIL (1 times)
test_bpf: #317 BSWAP 32: 0xfedcba9876543210 -> 0x10325476 jited:1 ret -1460850316 != 271733878 (0xa8ed3174 != 0x10325476)FAIL (1 times)
After:

LoongArch: BPF: Fix sign-extension mov instructions
We can see that "Short form of movsx, dst_reg = (s8,s16,s32)src_reg" in
include/linux/filter.h, additionally, for BPF_ALU64 the value of the
destination register is unchanged whereas for BPF_ALU the upper 32 bits
of the destination register are zeroed, so it should clear the upper 32
bits for BPF_ALU.
[root@linux fedora]# echo 1 > /proc/sys/net/core/bpf_jit_enable
[root@linux fedora]# modprobe test_bpf
Before:
test_bpf: #81 ALU_MOVSX | BPF_B jited:1 ret 2 != 1 (0x2 != 0x1)FAIL (1 times)
test_bpf: #82 ALU_MOVSX | BPF_H jited:1 ret 2 != 1 (0x2 != 0x1)FAIL (1 times)
After:
test_bpf: #81 ALU_MOVSX | BPF_B jited:1 6 PASS
test_bpf: #82 ALU_MOVSX | BPF_H jited:1 6 PASS
By the way, the bpf selftest case "./test_progs -t verifier_movsx" can
also be fixed with this patch.

This is because we signed-extend function return values. When subprog
mode is enabled, we have:
cls_redirect()
-> get_global_metrics() returns pcpu ptr 0xfffffefffc00b480
The pointer returned is later signed-extended to 0xfffffffffc00b480 at
`BPF_JMP | BPF_EXIT`. During BPF prog run, this triggers unhandled page
fault and a kernel panic.
Drop the unnecessary signed-extension on return values like other
architectures do.
With this change, we have:

Further investigation shows that this panic is triggered by memory
load operations:
ptr = bpf_cgrp_storage_get(&map_a, task->cgroups->dfl_cgrp, 0,
BPF_LOCAL_STORAGE_GET_F_CREATE);
The expression `task->cgroups->dfl_cgrp` involves two memory load.
Since the field offset fits in imm12 or imm14, we use ldd or ldptrd
instructions. But both instructions have the side effect that it will
signed-extended the imm operand. Finally, we got the wrong addresses
and panics is inevitable.
Use a generic ldxd instruction to avoid this kind of issues.
With this change, we have:

LoongArch: Preserve syscall nr across execve()
Currently, we store syscall nr in pt_regs::regs[11] and syscall execve()
accidentally overrides it during its execution:
sys_execve()
-> do_execve()
-> do_execveat_common()
-> bprm_execve()
-> exec_binprm()
-> search_binary_handler()
-> load_elf_binary()
-> ELF_PLAT_INIT()
ELF_PLAT_INIT() reset regs[11] to 0, so in syscall_exit_to_user_mode()
we later get a wrong syscall nr. This breaks tools like execsnoop since
it relies on execve() tracepoints.
Skip pt_regs::regs[11] reset in ELF_PLAT_INIT() to fix the issue.

LoongArch: Set unwind stack type to unknown rather than set error flag
During unwinding, unwind_done() is used as an end condition. Normally it unwind to the user stack and then set the stack type to unknown, which is a normal exit. When something unexpected happens in unwind process and we cannot unwind anymore, we should set the error flag, and also set the stack type to unknown to indicate that the unwind process can not continue. The error flag emphasizes that the unwind process produce an unexpected error. There is no unexpected things when we unwind the PT_REGS in the top of IRQ stack and find out that is an user mode PT_REGS. Thus, we should not set error flag and just set stack type to unknown.

LoongArch: Apply dynamic relocations for LLD
For the following assembly code:
.text
.global func
func:
nop
.data
var:
.dword func
When linked with `-pie`, GNU LD populates the `var` variable with the
pre-relocated value of `func`. However, LLVM LLD does not exhibit the
same behavior. This issue also arises with the `kernel_entry` in arch/
loongarch/kernel/head.S:
_head:
.word MZ_MAGIC /* "MZ", MS-DOS header */
.org 0x8
.dword kernel_entry /* Kernel entry point */
The correct kernel entry from the MS-DOS header is crucial for jumping
to vmlinux from zboot. This necessity is why the compressed relocatable
kernel compiled by Clang encounters difficulties in booting.
To address this problem, it is proposed to apply dynamic relocations to
place with `--apply-dynamic-relocs`.

KVM: SVM: Update EFER software model on CR0 trap for SEV-ES
In general, activating long mode involves setting the EFER_LME bit in the EFER register and then enabling the X86_CR0_PG bit in the CR0 register. At this point, the EFER_LMA bit will be set automatically by hardware. In the case of SVM/SEV guests where writes to CR0 are intercepted, it's necessary for the host to set EFER_LMA on behalf of the guest since hardware does not see the actual CR0 write. In the case of SEV-ES guests where writes to CR0 are trapped instead of intercepted, the hardware *does* see/record the write to CR0 before exiting and passing the value on to the host, so as part of enabling SEV-ES support commit |

KVM fixes for 6.7-rcN:
- When checking if a _running_ vCPU is "in-kernel", i.e. running at CPL0,
get the CPL directly instead of relying on preempted_in_kernel, which
is valid if and only if the vCPU was preempted, i.e. NOT running.
- Set .owner for various KVM file_operations so that files refcount the
KVM module until KVM is done executing _all_ code, including the last
few instructions of kvm_put_kvm(). And then revert the misguided
attempt to rely on "struct kvm" refcounts to pin KVM-the-module.
- Fix a benign "return void" that was recently introduced.

ARM: SoC fixes for v6.7
Most of the changes are devicetree fixes for NXP, Mediatek, Rockchips
Arm machines as well as Microchip RISC-V, and most of these address
build-time warnings for spec violations and other minor issues. One of
the Mediatek warnings was enabled by default and prevented a clean build.
The ones that address serious runtime issues are all on the i.MX platform:
- a boot time panic on imx8qm
- USB hanging under load on imx8
- regressions on the imx93 ethernet phy
Code fixes include a minor error handling for the i.MX PMU driver, and
a number of firmware driver fixes:
- OP-TEE fix for supplicant based device enumeration, and a new
sysfs attribute to needed to fix a race against userspace
- Arm SCMI fix for possible truncation/overflow in the frequency
computations
- Multiple FF-A fixes for the newly added notification support.

x86/tdx: Allow 32-bit emulation by default
32-bit emulation was disabled on TDX to prevent a possible attack by a VMM injecting an interrupt on vector 0x80. Now that int80_emulation() has a check for external interrupts the limitation can be lifted. To distinguish software interrupts from external ones, int80_emulation() checks the APIC ISR bit relevant to the 0x80 vector. For software interrupts, this bit will be 0. On TDX, the VAPIC state (including ISR) is protected and cannot be manipulated by the VMM. The ISR bit is set by the microcode flow during the handling of posted interrupts.

x86/entry: Do not allow external 0x80 interrupts
The INT 0x80 instruction is used for 32-bit x86 Linux syscalls. The kernel expects to receive a software interrupt as a result of the INT 0x80 instruction. However, an external interrupt on the same vector also triggers the same codepath. An external interrupt on vector 0x80 will currently be interpreted as a 32-bit system call, and assuming that it was a user context. Panic on external interrupts on the vector. To distinguish software interrupts from external ones, the kernel checks the APIC ISR bit relevant to the 0x80 vector. For software interrupts, this bit will be 0.

x86/entry: Convert INT 0x80 emulation to IDTENTRY
There is no real reason to have a separate ASM entry point implementation for the legacy INT 0x80 syscall emulation on 64-bit. IDTENTRY provides all the functionality needed with the only difference that it does not: - save the syscall number (AX) into pt_regs::orig_ax - set pt_regs::ax to -ENOSYS Both can be done safely in the C code of an IDTENTRY before invoking any of the syscall related functions which depend on this convention. Aside of ASM code reduction this prepares for detecting and handling a local APIC injected vector 0x80.

x86/coco: Disable 32-bit emulation by default on TDX and SEV
The INT 0x80 instruction is used for 32-bit x86 Linux syscalls. The
kernel expects to receive a software interrupt as a result of the INT
0x80 instruction. However, an external interrupt on the same vector
triggers the same handler.
The kernel interprets an external interrupt on vector 0x80 as a 32-bit
system call that came from userspace.
A VMM can inject external interrupts on any arbitrary vector at any
time. This remains true even for TDX and SEV guests where the VMM is
untrusted.
Put together, this allows an untrusted VMM to trigger int80 syscall
handling at any given point. The content of the guest register file at
that moment defines what syscall is triggered and its arguments. It
opens the guest OS to manipulation from the VMM side.
Disable 32-bit emulation by default for TDX and SEV. User can override
it with the ia32_emulation=y command line option.

bpf: Fix prog_array_map_poke_run map poke update
Lee pointed out issue found by syscaller [0] hitting BUG in prog array
map poke update in prog_array_map_poke_run function due to error value
returned from bpf_arch_text_poke function.
There's race window where bpf_arch_text_poke can fail due to missing
bpf program kallsym symbols, which is accounted for with check for
-EINVAL in that BUG_ON call.
The problem is that in such case we won't update the tail call jump
and cause imbalance for the next tail call update check which will
fail with -EBUSY in bpf_arch_text_poke.
I'm hitting following race during the program load:
CPU 0 CPU 1
bpf_prog_load
bpf_check
do_misc_fixups
prog_array_map_poke_track
map_update_elem
bpf_fd_array_map_update_elem
prog_array_map_poke_run
bpf_arch_text_poke returns -EINVAL
bpf_prog_kallsyms_add
After bpf_arch_text_poke (CPU 1) fails to update the tail call jump, the next
poke update fails on expected jump instruction check in bpf_arch_text_poke
with -EBUSY and triggers the BUG_ON in prog_array_map_poke_run.
Similar race exists on the program unload.
Fixing this by moving the update to bpf_arch_poke_desc_update function which
makes sure we call __bpf_arch_text_poke that skips the bpf address check.
Each architecture has slightly different approach wrt looking up bpf address
in bpf_arch_text_poke, so instead of splitting the function or adding new
'checkip' argument in previous version, it seems best to move the whole
map_poke_run update as arch specific code.

This is because we called riscv_noncoherent_supported() for all the stages
during IOCP probe. riscv_noncoherent_supported() function sets
noncoherent_supported variable to true which has an annotation set to
"__ro_after_init" due to which we were seeing the above splat. Fix this by
probing for IOCP only once in boot stage by having a boolean variable
"done" which will be set to true upon IOCP probe in errata_probe_iocp()
and we bail out early if "done" is set to true.
While at it make return type of errata_probe_iocp() to void as we were
not checking the return value in andes_errata_patch_func().

riscv: Fix SMP when shadow call stacks are enabled
This fixes two bugs in SCS initialization for secondary CPUs. First,
the SCS was not initialized at all in the spinwait boot path. Second,
the code for the SBI HSM path attempted to initialize the SCS before
enabling the MMU. However, that involves dereferencing the thread
pointer, which requires the MMU to be enabled.
Fix both issues by setting up the SCS in the common secondary entry
path, after enabling the MMU.

riscv: fix misaligned access handling of C.SWSP and C.SDSP
This is a backport of a fix that was done in OpenSBI: ec0559eb315b
("lib: sbi_misaligned_ldst: Fix handling of C.SWSP and C.SDSP").
Unlike C.LWSP/C.LDSP, these encodings can be used with the zero
register, so checking that the rs2 field is non-zero is unnecessary.
Additionally, the previous check was incorrect since it was checking
the immediate field of the instruction instead of the rs2 field.

RISC-V: hwprobe: Always use u64 for extension bits
Extensions are getting added quickly and their hwprobe bits will soon
exceed 31 (which pair values accommodate, since they're of type u64).
However, in one tree, where a bunch of extensions got merged prior to
zicboz, zicboz already got pushed to bit 32. Pushing it exposed a
32-bit compilation bug, since unsigned long was used instead of u64.

arm64: dts: rockchip: Fix eMMC Data Strobe PD on rk3588
JEDEC standard JESD84-B51 defines the eMMC Data Strobe line, which is
currently used only in HS400 mode, as a device->host clock signal that
"is used only in read operation. The Data Strobe is always High-Z (not
driven by the device and pulled down by RDS) or Driven Low in write
operation, except during CRC status response." RDS is a pull-down
resistor specified in the 10K-100K ohm range. Thus per the standard, the
Data Strobe is always pulled to ground (by the eMMC and/or RDS) during
write operations.
Evidently, the eMMC host controller in the RK3588 considers an active
voltage on the eMMC-DS line during a write to be an error.
The default (i.e. hardware reset, and Rockchip BSP) behavior for the
RK3588 is to activate the eMMC-DS pin's builtin pull-down. As a result,
many RK3588 board designers do not bother adding a dedicated RDS
resistor, instead relying on the RK3588's internal bias. The current
devicetree, however, disables this bias (`pcfg_pull_none`), breaking
HS400-mode writes for boards without a dedicated RDS, but with an eMMC
chip that chooses to High-Z (instead of drive-low) the eMMC-DS line.
(The Turing RK1 is one such board.)
Fix this by changing the bias in the (common) emmc_data_strobe case to
reflect the expected hardware/BSP behavior. This is unlikely to cause
regressions elsewhere: the pull-down is only relevant for High-Z eMMCs,
and if this is redundant with a (dedicated) RDS resistor, the effective
result is only a lower resistance to ground -- where the range of
tolerance is quite high. If it does, it's better fixed in the specific
devicetrees.
