ASoC: Fixes for v5.14
A collection of fixes for ASoC that have come in since the merge window,
all driver specific. There is a new core feature added for reversing
the order of operations when shutting down, this is needed to fix a bug
with the AMD Stonyridge platform, and we also tweak the Kconfig to make
the SSM2518 driver user selectable so it can be used with generic cards
but that requires no actual code changes.

Richard reported sporadic (roughly one in 10 or so) null dereferences and
other strange behaviour for a set of automated LTP tests. Things like:
BUG: kernel NULL pointer dereference, address: 0000000000000008
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
PGD 0 P4D 0
Oops: 0000 [#1] PREEMPT SMP PTI
CPU: 0 PID: 1516 Comm: umount Not tainted 5.10.0-yocto-standard #1
Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-48-gd9c812dda519-prebuilt.qemu.org 04/01/2014
RIP: 0010:kernfs_sop_show_path+0x1b/0x60
...or these others:

RIP: 0010:d_alloc_parallel+0x98/0x510
RIP: 0010:do_readlinkat+0x86/0x120
There were other less common instances of some kind of a general scribble
but the common theme was mount and cgroup and a dubious dentry triggering
the NULL dereference. I was only able to reproduce it under qemu by
replicating Richard's setup as closely as possible - I never did get it
to happen on bare metal, even while keeping everything else the same.
In commit 71d883c37e8d ("cgroup_do_mount(): massage calling conventions")
we see this as a part of the overall change:
--------------
struct cgroup_subsys *ss;
- struct dentry *dentry;
[...]
- dentry = cgroup_do_mount(&cgroup_fs_type, fc->sb_flags, root,
- CGROUP_SUPER_MAGIC, ns);
[...]
- if (percpu_ref_is_dying(&root->cgrp.self.refcnt)) {
- struct super_block *sb = dentry->d_sb;
- dput(dentry);
+ ret = cgroup_do_mount(fc, CGROUP_SUPER_MAGIC, ns);
+ if (!ret && percpu_ref_is_dying(&root->cgrp.self.refcnt)) {
+ struct super_block *sb = fc->root->d_sb;
+ dput(fc->root);
deactivate_locked_super(sb);
msleep(10);
return restart_syscall();
}
--------------
In changing from the local "*dentry" variable to using fc->root, we now
export/leave that dentry pointer in the file context after doing the dput()
in the unlikely "is_dying" case. With LTP doing a crazy amount of back to
back mount/unmount [testcases/bin/cgroup_regression_5_1.sh] the unlikely
becomes slightly likely and then bad things happen.
A fix would be to not leave the stale reference in fc->root as follows:
--------------
dput(fc->root);
+ fc->root = NULL;
deactivate_locked_super(sb);
--------------
...but then we are just open-coding a duplicate of fc_drop_locked() so we
simply use that instead.

To quote Alexey[1]:
I was adding custom tracepoint to the kernel, grabbed full F34 kernel
.config, disabled modules and booted whole shebang as VM kernel.
Then did
perf record -a -e ...
It crashed:
general protection fault, probably for non-canonical address 0x435f5346592e4243: 0000 [#1] SMP PTI
CPU: 1 PID: 842 Comm: cat Not tainted 5.12.6+ #26
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014
RIP: 0010:t_show+0x22/0xd0
Then reproducer was narrowed to
# cat /sys/kernel/tracing/printk_formats
Original F34 kernel with modules didn't crash.
So I started to disable options and after disabling AFS everything
started working again.
The root cause is that AFS was placing char arrays content into a
section full of _pointers_ to strings with predictable consequences.
Non canonical address 435f5346592e4243 is "CB.YFS_" which came from
CM_NAME macro.
Steps to reproduce:
CONFIG_AFS=y
CONFIG_TRACING=y
# cat /sys/kernel/tracing/printk_formats
Fix this by the following means:
(1) Add enum->string translation tables in the event header with the AFS
and YFS cache/callback manager operations listed by RPC operation ID.
(2) Modify the afs_cb_call tracepoint to print the string from the
translation table rather than using the string at the afs_call name
pointer.
(3) Switch translation table depending on the service we're being accessed
as (AFS or YFS) in the tracepoint print clause. Will this cause
problems to userspace utilities?
Note that the symbolic representation of the YFS service ID isn't
available to this header, so I've put it in as a number. I'm not sure
if this is the best way to do this.
(4) Remove the name wrangling (CM_NAME) macro and put the names directly
into the afs_call_type structs in cmservice.c.

The 8250 handle_irq callback is not just called from the interrupt
handler but also from a timer callback when polling (e.g. for ports
without an interrupt line). Consequently the callback must explicitly
disable interrupts to avoid a potential deadlock with another interrupt
in polled mode.
Add back an irqrestore-version of the sysrq port-unlock helper and use
it in the 8250 callbacks that need it.
Fixes: 75f4e830fa9c ("serial: do not restore interrupt state in sysrq helper")

This reverts commit c742199a014de23ee92055c2473d91fe5561ffdf.
c742199a014d ("mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge")
breaks arm64 in at least two ways for configurations where PUD or PMD
folding occur:
1. We no longer install huge-vmap mappings and silently fall back to
page-granular entries, despite being able to install block entries
at what is effectively the PGD level.
2. If the linear map is backed with block mappings, these will now
silently fail to be created in alloc_init_pud(), causing a panic
early during boot.
The pgtable selftests caught this, although a fix has not been
forthcoming and Christophe is AWOL at the moment, so just revert the
change for now to get a working -rc3 on which we can queue patches for
5.15.
A simple revert breaks the build for 32-bit PowerPC 8xx machines, which
rely on the default function definitions when the corresponding
page-table levels are folded, since commit a6a8f7c4aa7e ("powerpc/8xx:
add support for huge pages on VMAP and VMALLOC"), eg:
powerpc64-linux-ld: mm/vmalloc.o: in function `vunmap_pud_range':
linux/mm/vmalloc.c:362: undefined reference to `pud_clear_huge'
To avoid that, add stubs for pud_clear_huge() and pmd_clear_huge() in
arch/powerpc/mm/nohash/8xx.c as suggested by Christophe.

Currently TEE_SHM_DMA_BUF flag has been inappropriately used to not
register shared memory allocated for private usage by underlying TEE
driver: OP-TEE in this case. So rather add a new flag as TEE_SHM_PRIV
that can be utilized by underlying TEE drivers for private allocation
and usage of shared memory.
With this corrected, allow tee_shm_alloc_kernel_buf() to allocate a
shared memory region without the backing of dma-buf.

drm: Return -ENOTTY for non-drm ioctls
Return -ENOTTY from drm_ioctl() when userspace passes in a cmd number
which doesn't relate to the drm subsystem.
Glibc uses the TCGETS ioctl to implement isatty(), and without this
change isatty() returns it incorrectly returns true for drm devices.
To test run this command:
$ if [ -t 0 ]; then echo is a tty; fi < /dev/dri/card0
which shows "is a tty" without this patch.
This may also modify memory which the userspace application is not
expecting.

After mq-deadline learned to deal with cgroups, the BLKCG_MAX_POLS value
became too small for all the elevators to be registered properly. The
following issue is seen:
```

blkcg_policy_register: BLKCG_MAX_POLS too small
initcall bfq_init+0x0/0x8b returned -28 after 507 usecs
```
which renders BFQ non-functional.

Now that all architectures provide arch_atomic_long_*(), we can
implement the generic bitops atop these rather than atop
atomic_long_*(), and provide arch_*() forms of the bitops that are safe
to use in noinstr code.
Now that all architectures provide arch_atomic_long_*(), we can
build the generic arch_*() bitops atop these, which can be safely used
in noinstr code. The regular bitop wrappers are built atop these.
As the generic non-atomic bitops use plain accesses, these will be
implicitly instrumented unless they are inlined into noinstr functions
(which is similar to arch_atomic*_read() when based on READ_ONCE()).
The wrappers are modified so that where the underlying arch_*() function
uses a plain access, no explicit instrumentation is added, as this is
redundant and could result in confusing reports.
Since function prototypes get excessively long with both an `arch_`
prefix and `__always_inline` attribute, the return type and function
attributes have been split onto a separate line, matching the style of
the generated atomic headers.

Now that all architectures provide arch_{atomic,atomic64}_*(), we can
build arch_atomic_long_*() atop these, which can be safely used in
noinstr code. The regular atomic_long_*() wrappers are built atop these,
as we do for {atomic,atomic64}_*() atop arch_{atomic,atomic64}_*().
We don't provide arch_* versions of the cond_read*() variants, as we
don't have arch_* versions of the underlying atomic/atomic64 functions
(nor the smp_cond_load*() helpers these are typically based on).

In 7fedb63a8307 ("bpf: Tighten speculative pointer arithmetic mask") we
narrowed the offset mask for unprivileged pointer arithmetic in order to
mitigate a corner case where in the speculative domain it is possible to
advance, for example, the map value pointer by up to value_size-1 out-of-
bounds in order to leak kernel memory via side-channel to user space.
The verifier's state pruning for scalars leaves one corner case open
where in the first verification path R_x holds an unknown scalar with an
aux->alu_limit of e.g. 7, and in a second verification path that same
register R_x, here denoted as R_x', holds an unknown scalar which has
tighter bounds and would thus satisfy range_within(R_x, R_x') as well as
tnum_in(R_x, R_x') for state pruning, yielding an aux->alu_limit of 3:
Given the second path fits the register constraints for pruning, the final
generated mask from aux->alu_limit will remain at 7. While technically
not wrong for the non-speculative domain, it would however be possible
to craft similar cases where the mask would be too wide as in 7fedb63a8307.
One way to fix it is to detect the presence of unknown scalar map pointer
arithmetic and force a deeper search on unknown scalars to ensure that
we do not run into a masking mismatch.

This patch adds a driver for PCHG (Peripheral CHarGer). PCHG is a
framework managing power supplies for peripheral devices.
This driver creates a sysfs node for each peripheral charge port:
/sys/class/power_supply/peripheral<n>
where <n> is the index of a charge port.
For example, when a stylus is connected to a NFC/WLC port, the node
returns:
/sys/class/power_supply/peripheral0/
capacity=50
charge_type=Standard
scope=Device
status=Charging
type=Battery

Pull fallthrough fixes from Gustavo Silva:
"This fixes many fall-through warnings when building with Clang and
-Wimplicit-fallthrough, and also enables -Wimplicit-fallthrough for
Clang, globally.
It's also important to notice that since we have adopted the use of
the pseudo-keyword macro fallthrough, we also want to avoid having
more /* fall through */ comments being introduced. Contrary to GCC,
Clang doesn't recognize any comments as implicit fall-through markings
when the -Wimplicit-fallthrough option is enabled.
So, in order to avoid having more comments being introduced, we use
the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang,
will cause a warning in case a code comment is intended to be used as
a fall-through marking. The patch for Makefile also enforces this.
We had almost 4,000 of these issues for Clang in the beginning, and
there might be a couple more out there when building some
architectures with certain configurations. However, with the recent
fixes I think we are in good shape and it is now possible to enable
the warning for Clang"

ISH IPC driver uses asynchronous workqueue to do resume now, but there is
a potential timing issue: when child devices resume before bus driver, it
will cause child devices resume failed and cannot be recovered until
reboot. The current implementation in this case do wait for IPC to resume
but fail to accommodate for a case when there is no ISH reboot and soft
resume is taking time. This issue is apparent on Tiger Lake platform with
5.11.13 kernel when doing suspend to idle then resume(s0ix) test. To
resolve this issue, we change ISHTP HID client to use asynchronous resume
callback too. In the asynchronous resume callback, it waits for the ISHTP
resume done event, and then notify ISHTP HID client link ready.

Tracepoint trace_qdisc_enqueue() is introduced to trace skb at
the entrance of TC layer on TX side. This is similar to
trace_qdisc_dequeue():
1. For both we only trace successful cases. The failure cases
can be traced via trace_kfree_skb().
2. They are called at entrance or exit of TC layer, not for each
->enqueue() or ->dequeue(). This is intentional, because
we want to make trace_qdisc_enqueue() symmetric to
trace_qdisc_dequeue(), which is easier to use.
The return value of qdisc_enqueue() is not interesting here,
we have Qdisc's drop packets in ->dequeue(), it is impossible to
trace them even if we have the return value, the only way to trace
them is tracing kfree_skb().
We only add information we need to trace ring buffer. If any other
information is needed, it is easy to extend it without breaking ABI,

Currently, serializing operations such as page fault, read, or readahead
against hole punching is rather difficult. The basic race scheme is
like:
fallocate(FALLOC_FL_PUNCH_HOLE) read / fault / ..
truncate_inode_pages_range()
<create pages in page
cache here>
<update fs block mapping and free blocks>
Now the problem is in this way read / page fault / readahead can
instantiate pages in page cache with potentially stale data (if blocks
get quickly reused). Avoiding this race is not simple - page locks do
not work because we want to make sure there are *no* pages in given
range. inode->i_rwsem does not work because page fault happens under
mmap_sem which ranks below inode->i_rwsem. Also using it for reads makes
the performance for mixed read-write workloads suffer.
So create a new rw_semaphore in the address_space - invalidate_lock -
that protects adding of pages to page cache for page faults / reads /
readahead.

APIs" from Alexandru Ardelean <aardelean@deviqon.com>:
These APIs aren't used anywhere and most-likely exist because of the
general principle of C APIs, where if an API function does an
allocation/registration, it must also have an equivalent
deallocation/deregistration counterpart.
For devm_ functions this isn't all that true (for all cases), as the idea
of these function is to provide an auto-cleanup logic on drivers/system
de-init.
Removing these discourages any weird logic that could be created with
such an API functions.
