bpf, arm64: Remove garbage frame for struct_ops trampoline

bpf, arm64: Remove garbage frame for struct_ops trampoline

[ Upstream commit 87cb58aebdf7005661a07e9fd5a900f924d48c75 ]

The callsite layout for arm64 fentry is:

mov x9, lr
nop

When a bpf prog is attached, the nop instruction is patched to a call
to bpf trampoline:

mov x9, lr
bl <bpf trampoline>

So two return addresses are passed to bpf trampoline: the return address
for the traced function/prog, stored in x9, and the return address for
the bpf trampoline itself, stored in lr. To obtain a full and accurate
call stack, the bpf trampoline constructs two fake function frames using
x9 and lr.

However, struct_ops progs are invoked directly as function callbacks,
meaning that x9 is not set as it is in the fentry callsite. In this case,
the frame constructed using x9 is garbage. The following stack trace for
struct_ops, captured by perf sampling, illustrates this issue, where
tcp_ack+0x404 is a garbage frame:

ffffffc0801a04b4 bpf_prog_50992e55a0f655a9_bpf_cubic_cong_avoid+0x98 (bpf_prog_50992e55a0f655a9_bpf_cubic_cong_avoid)
ffffffc0801a228c [unknown] ([kernel.kallsyms]) // bpf trampoline
ffffffd08d362590 tcp_ack+0x798 ([kernel.kallsyms]) // caller for bpf trampoline
ffffffd08d3621fc tcp_ack+0x404 ([kernel.kallsyms]) // garbage frame
ffffffd08d36452c tcp_rcv_established+0x4ac ([kernel.kallsyms])
ffffffd08d375c58 tcp_v4_do_rcv+0x1f0 ([kernel.kallsyms])
ffffffd08d378630 tcp_v4_rcv+0xeb8 ([kernel.kallsyms])

To fix it, construct only one frame using lr for struct_ops.

The above stack trace also indicates that there is no kernel symbol for
struct_ops bpf trampoline. This will be addressed in a follow-up patch.

When __bpf_prog_enter() returns zero, the arm64 register x20 that stores

To fix it, assign the return value of bpf_prog_enter() to x20 register
immediately upon its return.

bpf, arm64: fix bug in BPF_LDX_MEMSX

[ Upstream commit 114b5b3b4bde7358624437be2f12cde1b265224e ]

A64_LDRSW() takes three registers: Xt, Xn, Xm as arguments and it loads
and sign extends the value

bpf, arm64: fix bug in BPF_LDX_MEMSX

[ Upstream commit 114b5b3b4bde7358624437be2f12cde1b265224e ]

A64_LDRSW() takes three registers: Xt, Xn, Xm as arguments and it loads
and sign extends the value at address Xn + Xm into register Xt.

Currently, the offset is being directly used in place of the tmp
register which has the offset already loaded by the last emitted
instruction.

This will cause JIT failures. The easiest way to reproduce this is to
test the following code through test_bpf module:

{
"BPF_LDX_MEMSX | BPF_W",
.u.insns_int = {
BPF_LD_IMM64(R1, 0x00000000deadbeefULL),
BPF_LD_IMM64(R2, 0xffffffffdeadbeefULL),
BPF_STX_MEM(BPF_DW, R10, R1, -7),
BPF_LDX_MEMSX(BPF_W, R0, R10, -7),
BPF_JMP_REG(BPF_JNE, R0, R2, 1),
BPF_ALU64_IMM(BPF_MOV, R0, 0),
BPF_EXIT_INSN(),
},
INTERNAL,
{ },
{ { 0, 0 } },
.stack_depth = 7,
},

We need to use the offset as -7 to trigger this code path, there could
be other valid ways to trigger this from proper BPF programs as well.

This code is rejected by the JIT because -7 is passed to A64_LDRSW() but
it expects a valid register (0 - 31).

Merge drm/drm-next into drm-intel-next

Catching-up with drm-next and drm-intel-gt-next.
It will unblock a code refactor around the platform
definitions (names vs acronyms).

A collection of device specific fixes, none particularly remarkable.
There's a set of repetitive fixes for the RealTek drivers fixing an
issue with suspend that was replicated in multiple drivers.

ASoC: Updates for v6.6

Here's an initial batch of updates for ASoC for this release cycle.
We've got a bunch of new drivers in here, a bit of core work from
Morimoto-san and quite a lot of janitorial work. There's several
updates that pull in changes from other subsystems in order to build
on them:

- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes.
- Create a library function for intlog10() and use it in the NAU8825
driver.
- Include the ASoC tests, including the topology tests, in the default
KUnit full test coverage. This also involves enabling UML builds of
ALSA since that's the default KUnit test environment which pulls in
the addition of some stubs to the driver.
- More factoring out from Morimoto-san.
- Convert a lot of drivers to use the more modern maple tree register
cache.
- Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic
CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.
