commit 61890dc28f7d9e9aac8a9471302613824c22fae4 upstream.
The commit 89ff3dfac604 ("usb: gadget: f_hid: fix f_hidg lifetime vs
cdev") has introduced a bug that leads to hid device corruption after
the replug operation.
Reverse device managed memory allocation for the report descriptor
to fix the issue.
Tested:
This change was tested on the AMD EthanolX CRB server with the BMC
based on the OpenBMC distribution. The BMC provides KVM functionality
via the USB gadget device:
- before: KVM page refresh results in a broken USB device,
- after: KVM page refresh works without any issues.
Fixes: 89ff3dfac604 ("usb: gadget: f_hid: fix f_hidg lifetime vs cdev")

As soon as control->i2c_address is set, return; remove the "break;" from the
switch--it is unnecessary. This mimics what happens when for some cases in the
switch, we call helper functions with "return <helper function>".
Remove final function "return true;" to indicate that the switch is final and

Abstract RAS I2C EEPROM addresses from chip names, and set their macro
definition names to the address they set, not the chip they attach
to. Since most chips either use I2C EEPROM address 0 or 40000h for the RAS
table start offset, this leaves us with only two macro definitions as
opposed to five, and removes the redundancy of four.

[ Upstream commit 95dd1e34ff5bbee93a28ff3947eceaf6de811b1a ]
If gpio_set_transitory() fails, we should free the GPIO again. Most
notably, the flag FLAG_REQUESTED has previously been set in
gpiod_request_commit(), and should be reset on failure.
To my knowledge, this does not affect any current users, since the
gpio_set_transitory() mainly returns 0 and -ENOTSUPP, which is converted
to 0. However the gpio_set_transitory() function calles the .set_config()
function of the corresponding GPIO chip and there are some GPIO drivers in
which some (unlikely) branches return other values like -EPROBE_DEFER,
and -EINVAL. In these cases, the above mentioned FLAG_REQUESTED would not
be reset, which results in the pin being blocked until the next reboot.

[ Upstream commit 27d25348d42161837be08fc63b04a2559d2e781c ]
A write-access violation page fault kernel crash was observed while running
cpuhotplug LTP testcases on SEV-ES enabled systems. The crash was
observed during hotplug, after the CPU was offlined and the process
was migrated to different CPU. setup_ghcb() is called again which
tries to update ghcb_version in sev_es_negotiate_protocol(). Ideally this
is a read_only variable which is initialised during booting.
Trying to write it results in a pagefault:

[ Upstream commit d78ab792705c7be1b91243b2544d1a79406a2ad7 ]
When the ring buffer is being resized, it can cause side effects to the
running tracer. For instance, there's a race with irqsoff tracer that
swaps individual per cpu buffers between the main buffer and the snapshot
buffer. The resize operation modifies the main buffer and then the
snapshot buffer. If a swap happens in between those two operations it will
break the tracer.
Simply stop the running tracer before resizing the buffers and enable it
again when finished.

There's a race where if an event is discarded from the ring buffer and an
interrupt were to happen at that time and insert an event, the time stamp
is still used from the discarded event as an offset. This can screw up the
timings.
If the event is going to be discarded, set the "before_stamp" to zero.
When a new event comes in, it compares the "before_stamp" with the
"write_stamp" and if they are not equal, it will insert an absolute
timestamp. This will prevent the timings from getting out of sync due to
the discarded event.

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:

[ Upstream commit 348ddab81f7b0983d9fb158df910254f08d3f887 ]
etm4_platform_driver (which lives in ".data" contains a reference to
etm4_remove_platform_dev(). So the latter must not be marked with __exit
which results in the function being discarded for a build with
CONFIG_CORESIGHT_SOURCE_ETM4X=y which in turn makes the remove pointer
contain invalid data.
etm4x_amba_driver referencing etm4_remove_amba() has the same issue.
Drop the __exit annotations for the two affected functions and a third
one that is called by the other two.
For reasons I don't understand this isn't catched by building with
CONFIG_DEBUG_SECTION_MISMATCH=y.

commit 1aa3aaf8953c84bad398adf6c3cabc9d6685bf7d upstream
A transaction complete work is allocated and queued for each
transaction. Under certain conditions the work->type might be marked as
BINDER_WORK_TRANSACTION_ONEWAY_SPAM_SUSPECT to notify userspace about
potential spamming threads or as BINDER_WORK_TRANSACTION_PENDING when
the target is currently frozen.
However, these work types are not being handled in binder_release_work()
so they will leak during a cleanup. This was reported by syzkaller with
the following kmemleak dump:

commit 9dea1c724fc36643e83216c1f5a26613412150db upstream.
The NTC is defined as ntc@0 but it doesn't need any address at all.
Fix the unit_address_vs_reg warning by dropping the unit address: since
the node name has to be generic also fully rename it from ntc@0 to
thermal-sensor.

commit 61b94d54421a1f3670ddd5396ec70afe833e9405 upstream.
Before suspending the LARBs we're making sure that any operation is
done: this never happens because we are unexpectedly unclocking the
LARB20 before executing the suspend handler for the MediaTek Smart
Multimedia Interface (SMI) and the cause of this is incorrect clocks
on this LARB.
Fix this issue by changing the Local Arbiter 20 (used by the video
encoder secondary core) apb clock to CLK_VENC_CORE1_VENC;
furthermore, in order to make sure that both the PM resume and video
encoder operation is stable, add the CLK_VENC(_CORE1)_LARB clock to
the VENC (main core) and VENC_CORE1 power domains, as this IP cannot
communicate with the rest of the system (the AP) without local
arbiter clocks being operational.
