x86/CPU/AMD: Save AMD NodeId as cpu_die_id
[ Upstream commit 028c221ed1904af9ac3c5162ee98f48966de6b3d ] AMD systems provide a "NodeId" value that represents a global ID indicating to which "Node" a logical CPU belongs. The "Node" is a physical structure equivalent to a Die, and it should not be confused with logical structures like NUMA nodes. Logical nodes can be adjusted based on firmware or other settings whereas the physical nodes/dies are fixed based on hardware topology. The NodeId value can be used when a physical ID is needed by software. Save the AMD NodeId to struct cpuinfo_x86.cpu_die_id. Use the value from CPUID or MSR as appropriate. Default to phys_proc_id otherwise. Do so for both AMD and Hygon systems. Drop the node_id parameter from cacheinfo_*_init_llc_id() as it is no longer needed. Update the x86 topology documentation.

Revert: "ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS"
commit adab66b71abfe206a020f11e561f4df41f0b2aba upstream.
It was believed that metag was the only architecture that required the ring
buffer to keep 8 byte words aligned on 8 byte architectures, and with its
removal, it was assumed that the ring buffer code did not need to handle
this case. It appears that sparc64 also requires this.
The following was reported on a sparc64 boot up:
kernel: futex hash table entries: 65536 (order: 9, 4194304 bytes, linear)

regulator: axp20x: Fix DLDO2 voltage control register mask for AXP22x
commit 291de1d102fafef0798cdad9666cd4f8da7da7cc upstream.
When I use the axp20x chip to power my SDIO device on the 5.4 kernel,
the output voltage of DLDO2 is wrong. After comparing the register
manual and source code of the chip, I found that the mask bit of the
driver register of the port was wrong. I fixed this error by modifying
the mask register of the source code. This error seems to be a copy
error of the macro when writing the code. Now the voltage output of
the DLDO2 port of axp20x is correct. My development environment is
Allwinner A40I of arm architecture, and the kernel version is 5.4.

platform/x86: intel-vbtn: Allow switch events on Acer Switch Alpha 12
commit fe6000990394639ed374cb76c313be3640714f47 upstream.
This 2-in-1 model (Product name: Switch SA5-271) features a SW_TABLET_MODE
that works as it would be expected, both when detaching the keyboard and
when folding it behind the tablet body.
It used to work until the introduction of the allow list at
commit 8169bd3e6e193 ("platform/x86: intel-vbtn: Switch to an allow-list
for SW_TABLET_MODE reporting"). Add this model to it, so that the Virtual
Buttons device announces the EV_SW features again.

libnvdimm/namespace: Fix reaping of invalidated block-window-namespace labels
commit 2dd2a1740ee19cd2636d247276cf27bfa434b0e2 upstream.
A recent change to ndctl to attempt to reconfigure namespaces in place
uncovered a label accounting problem in block-window-type namespaces.
The ndctl "create.sh" test is able to trigger this signature:
WARNING: CPU: 34 PID: 9167 at drivers/nvdimm/label.c:1100 __blk_label_update+0x9a3/0xbc0 [libnvdimm]
[..]
RIP: 0010:__blk_label_update+0x9a3/0xbc0 [libnvdimm]
[..]
Call Trace:

kernfs_fop_write+0xcf/0x1c0
vfs_write+0xcc/0x380
ksys_write+0x68/0xe0
When allocated capacity for a namespace is renamed (new UUID) the labels
with the old UUID need to be deleted. The ndctl behavior to always
destroy namespaces on reconfiguration hid this problem.
The immediate impact of this bug is limited since block-window-type
namespaces only seem to exist in the specification and not in any
shipping products. However, the label handling code is being reused for
other technologies like CXL region labels, so there is a benefit to
making sure both vertical labels sets (block-window) and horizontal
label sets (pmem) have a functional reference implementation in
libnvdimm.

xenbus/xenbus_backend: Disallow pending watch messages
commit 9996bd494794a2fe393e97e7a982388c6249aa76 upstream. 'xenbus_backend' watches 'state' of devices, which is writable by guests. Hence, if guests intensively updates it, dom0 will have lots of pending events that exhausting memory of dom0. In other words, guests can trigger dom0 memory pressure. This is known as XSA-349. However, the watch callback of it, 'frontend_changed()', reads only 'state', so doesn't need to have the pending events. To avoid the problem, this commit disallows pending watch messages for 'xenbus_backend' using the 'will_handle()' watch callback.

xen/xenbus: Allow watches discard events before queueing
commit fed1755b118147721f2c87b37b9d66e62c39b668 upstream. If handling logics of watch events are slower than the events enqueue logic and the events can be created from the guests, the guests could trigger memory pressure by intensively inducing the events, because it will create a huge number of pending events that exhausting the memory. Fortunately, some watch events could be ignored, depending on its handler callback. For example, if the callback has interest in only one single path, the watch wouldn't want multiple pending events. Or, some watches could ignore events to same path. To let such watches to volutarily help avoiding the memory pressure situation, this commit introduces new watch callback, 'will_handle'. If it is not NULL, it will be called for each new event just before enqueuing it. Then, if the callback returns false, the event will be discarded. No watch is using the callback for now, though.

xen-blkback: set ring->xenblkd to NULL after kthread_stop()
commit 1c728719a4da6e654afb9cc047164755072ed7c9 upstream.
When xen_blkif_disconnect() is called, the kernel thread behind the
block interface is stopped by calling kthread_stop(ring->xenblkd).
The ring->xenblkd thread pointer being non-NULL determines if the
thread has been already stopped.
Normally, the thread's function xen_blkif_schedule() sets the
ring->xenblkd to NULL, when the thread's main loop ends.
However, when the thread has not been started yet (i.e.
wake_up_process() has not been called on it), the xen_blkif_schedule()
function would not be called yet.
In such case the kthread_stop() call returns -EINTR and the
ring->xenblkd remains dangling.
When this happens, any consecutive call to xen_blkif_disconnect (for
example in frontend_changed() callback) leads to a kernel crash in
kthread_stop() (e.g. NULL pointer dereference in exit_creds()).
This is XSA-350.

clk: ingenic: Fix divider calculation with div tables
commit 11a163f2c7d6a9f27ce144cd7e367a81c851621a upstream.
The previous code assumed that a higher hardware value always resulted
in a bigger divider, which is correct for the regular clocks, but is
an invalid assumption when a divider table is provided for the clock.
Perfect example of this is the PLL0_HALF clock, which applies a /2
divider with the hardware value 0, and a /1 divider otherwise.

pinctrl: sunxi: Always call chained_irq_{enter, exit} in sunxi_pinctrl_irq_handler
commit a1158e36f876f6269978a4176e3a1d48d27fe7a1 upstream. It is found on many allwinner soc that there is a low probability that the interrupt status cannot be read in sunxi_pinctrl_irq_handler. This will cause the interrupt status of a gpio bank to always be active on gic, preventing gic from responding to other spi interrupts correctly.

md/cluster: fix deadlock when node is doing resync job
commit bca5b0658020be90b6b504ca514fd80110204f71 upstream.
md-cluster uses MD_CLUSTER_SEND_LOCK to make node can exclusively send msg.
During sending msg, node can concurrently receive msg from another node.
When node does resync job, grab token_lockres:EX may trigger a deadlock:
```
nodeA nodeB
-------------------- --------------------
a.
send METADATA_UPDATED
held token_lockres:EX
b.
md_do_sync
resync_info_update
send RESYNCING
+ set MD_CLUSTER_SEND_LOCK
+ wait for holding token_lockres:EX
c.
mdadm /dev/md0 --remove /dev/sdg
+ held reconfig_mutex
+ send REMOVE
+ wait_event(MD_CLUSTER_SEND_LOCK)
d.
recv_daemon //METADATA_UPDATED from A
process_metadata_update
+ (mddev_trylock(mddev) ||
MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD)
//this time, both return false forever
```
Explaination:
a. A send METADATA_UPDATED
This will block another node to send msg
b. B does sync jobs, which will send RESYNCING at intervals.
This will be block for holding token_lockres:EX lock.
c. B do "mdadm --remove", which will send REMOVE.
This will be blocked by step <b>: MD_CLUSTER_SEND_LOCK is 1.
d. B recv METADATA_UPDATED msg, which send from A in step <a>.
This will be blocked by step <c>: holding mddev lock, it makes
wait_event can't hold mddev lock. (btw,
MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD keep ZERO in this scenario.)
There is a similar deadlock in commit

md/cluster: block reshape with remote resync job
commit a8da01f79c89755fad55ed0ea96e8d2103242a72 upstream.
Reshape request should be blocked with ongoing resync job. In cluster
env, a node can start resync job even if the resync cmd isn't executed
on it, e.g., user executes "mdadm --grow" on node A, sometimes node B
will start resync job. However, current update_raid_disks() only check
local recovery status, which is incomplete. As a result, we see user will
execute "mdadm --grow" successfully on local, while the remote node deny
to do reshape job when it doing resync job. The inconsistent handling
cause array enter unexpected status. If user doesn't observe this issue
and continue executing mdadm cmd, the array doesn't work at last.
Fix this issue by blocking reshape request. When node executes "--grow"
and detects ongoing resync, it should stop and report error to user.
The following script reproduces the issue with ~100% probability.
(two nodes share 3 iSCSI luns: sdg/sdh/sdi. Each lun size is 1GB)
```
# on node1, node2 is the remote node.
ssh root@node2 "mdadm -S --scan"
mdadm -S --scan
for i in {g,h,i};do dd if=/dev/zero of=/dev/sd$i oflag=direct bs=1M \
count=20; done
mdadm -C /dev/md0 -b clustered -e 1.2 -n 2 -l mirror /dev/sdg /dev/sdh
ssh root@node2 "mdadm -A /dev/md0 /dev/sdg /dev/sdh"
sleep 5
mdadm --manage --add /dev/md0 /dev/sdi
mdadm --wait /dev/md0
mdadm --grow --raid-devices=3 /dev/md0
mdadm /dev/md0 --fail /dev/sdg
mdadm /dev/md0 --remove /dev/sdg

iio:adc:ti-ads124s08: Fix alignment and data leak issues.
commit 1e405bc2512f80a903ddd6ba8740cee885238d7f upstream.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp() assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data with alignment
explicitly requested. This data is allocated with kzalloc() so no
data can leak apart from previous readings.
In this driver the timestamp can end up in various different locations
depending on what other channels are enabled. As a result, we don't
use a structure to specify it's position as that would be misleading.

The buffer is expressed as a u32 array, yet the extra space for

This will result in 2 extra u32 elements.
Fix by dividing by sizeof(u32).

As such the buffer does not need to be as long as stated.

iio:pressure:mpl3115: Force alignment of buffer
commit 198cf32f0503d2ad60d320b95ef6fb8243db857f upstream.
Whilst this is another case of the issue Lars reported with
an array of elements of smaller than 8 bytes being passed
to iio_push_to_buffers_with_timestamp(), the solution here is
a bit different from the other cases and relies on __aligned
working on the stack (true since 4.6?)
This one is unusual. We have to do an explicit memset() each time
as we are reading 3 bytes into a potential 4 byte channel which
may sometimes be a 2 byte channel depending on what is enabled.
As such, moving the buffer to the heap in the iio_priv structure
doesn't save us much. We can't use a nice explicit structure
on the stack either as the data channels have different storage
sizes and are all separately controlled.

iio: buffer: Fix demux update
commit 19ef7b70ca9487773c29b449adf0c70f540a0aab upstream.
When updating the buffer demux, we will skip a scan element from the
device in the case `in_ind != out_ind` and we enter the while loop.
in_ind should only be refreshed with `find_next_bit()` in the end of the
loop.
Note, to cause problems we need a situation where we are skippig over
an element (channel not enabled) that happens to not have the same size
as the next element. Whilst this is a possible situation we haven't
actually identified any cases in mainline where it happens as most drivers
have consistent channel storage sizes with the exception of the timestamp
which is the last element and hence never skipped over.

mtd: parser: cmdline: Fix parsing of part-names with colons
commit 639a82434f16a6df0ce0e7c8595976f1293940fd upstream.
Some devices (especially QCA ones) are already using hardcoded partition
names with colons in it. The OpenMesh A62 for example provides following
mtd relevant information via cmdline:
root=31:11 mtdparts=spi0.0:256k(0:SBL1),128k(0:MIBIB),384k(0:QSEE),64k(0:CDT),64k(0:DDRPARAMS),64k(0:APPSBLENV),512k(0:APPSBL),64k(0:ART),64k(custom),64k(0:KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive) rootfsname=rootfs rootwait
The change to split only on the last colon between mtd-id and partitions
will cause newpart to see following string for the first partition:
KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive)
Such a partition list cannot be parsed and thus the device fails to boot.
Avoid this behavior by making sure that the start of the first part-name
("(") will also be the last byte the mtd-id split algorithm is using for
its colon search.

smp2p_update_bits() should disable interrupts when it acquires its

inversion can occur.
This function is called both with interrupts enabled in
qcom_q6v5_request_stop(), and with interrupts disabled in
ipa_smp2p_panic_notifier(). IRQ handling of spinlocks should be
consistent to avoid the panic notifier deadlocking because it's
sitting on the thread that's already got the lock via _request_stop().

teardown step because bus accesses may still be ongoing until that
function returns.
All of these bugs have existed since the driver was first introduced,
so it seems fair to fix them together in a single commit.

spi: mt7621: Disable clock in probe error path
commit 24f7033405abe195224ec793dbc3d7a27dec0b98 upstream.
Commit 702b15cb9712 ("spi: mt7621: fix missing clk_disable_unprepare()
on error in mt7621_spi_probe") sought to disable the SYS clock on probe
errors, but only did so for 2 of 3 potentially failing calls: The clock
needs to be disabled on failure of devm_spi_register_controller() as
well.
Moreover, the commit purports to fix a bug in commit

spi: synquacer: Disable clock in probe error path
commit 8853b2503014aca5c793d2c7f0aabc990b32bdad upstream.
If the calls to platform_get_irq() or devm_request_irq() fail on probe
of the SynQuacer SPI driver, the clock "sspi->clk" is erroneously not
unprepared and disabled.
If the clock rate "master->max_speed_hz" cannot be determined, the same
happens and in addition the spi_master struct is not freed.
Fix it.

spi: st-ssc4: Fix unbalanced pm_runtime_disable() in probe error path
commit 5ef76dac0f2c26aeae4ee79eb830280f16d5aceb upstream.
If the calls to devm_platform_ioremap_resource(), irq_of_parse_and_map()
or devm_request_irq() fail on probe of the ST SSC4 SPI driver, the
runtime PM disable depth is incremented even though it was not
decremented before. Fix it.

spi: sc18is602: Don't leak SPI master in probe error path
commit 5b8c88462d83331dacb48aeaec8388117fef82e0 upstream.
If the call to devm_gpiod_get_optional() fails on probe of the NXP
SC18IS602/603 SPI driver, the spi_master struct is erroneously not freed.
Fix by switching over to the new devm_spi_alloc_master() helper.

spi: rb4xx: Don't leak SPI master in probe error path
commit a4729c3506c3eb1a6ca5c0289f4e7cafa4115065 upstream.
If the calls to devm_clk_get(), devm_spi_register_master() or
clk_prepare_enable() fail on probe of the Mikrotik RB4xx SPI driver,
the spi_master struct is erroneously not freed.
Fix by switching over to the new devm_spi_alloc_master() helper.

spi: pic32: Don't leak DMA channels in probe error path
commit c575e9113bff5e024d75481613faed5ef9d465b2 upstream.
If the calls to devm_request_irq() or devm_spi_register_master() fail
on probe of the PIC32 SPI driver, the DMA channels requested by
pic32_spi_dma_prep() are erroneously not released. Plug the leak.
