ASoC: Fixes for v5.19
A collection of fixes for v5.19, quite large but nothing major - a good
chunk of it is more stuff that was identified by mixer-test regarding
event generation.
|

The patch applies the same quirks used for SC-01 at firmware v1.1.0 to
the ones running v1.0.0, with respect to hard-coded sample rates.
I got two more units and successfully tested the patch series with both
firmwares.
The support is now complete (not accounting ASIO).

Fiero SC-01 is a USB sound card with two mono inputs and a single
stereo output. The inputs are composed into a single stereo stream.
The device uses a vendor-provided driver on Windows and does not work
at all without it. The driver mostly provides ASIO functionality, but
also alters the way the sound card is queried for sample rates and
clocks.
ALSA queries those failing with an EPIPE (same as Windows 10 does).
Presumably, the vendor-provided driver does not query it at all, simply
matching by VID:PID. Thus, I consider this a buggy firmware and adhere
to a set of fixed endpoint quirks instead.
The soundcard has an internal clock. Implicit feedback mode is required
for the playback.
I have updated my device to v1.1.0 from a Windows 10 VM using a vendor-
provided binary prior to the development, hoping for it to just begin
working. The device provides no obvious way to downgrade the firmware,
and regardless, there's no binary available for v1.0.0 anyway.
Thus, I will be getting another unit to extend the patch with support
for that. Expected to be a simple copy-paste of the existing one,
though.
There were no previous reports of that device in context of Linux
anywhere. Other issues have been reported though, but that's out of the
scope.

Always run fbdev removal first to remove simpledrm via
sysfb_disable(). This clears the internal state. The later call
to drm_aperture_detach_drivers() then does nothing. Otherwise,
with drm_aperture_detach_drivers() running first, the call to
sysfb_disable() uses inconsistent state.

In mcp251xfd_register_get_dev_id() the device ID register is read with
handcrafted SPI transfers. As all registers, this register is in
little endian. Further it is not naturally aligned in struct
mcp251xfd_map_buf_nocrc::data. However after the transfer the register
content is converted from big endian to CPU endianness not taking care
of being unaligned.
Fix the conversion by converting from little endian to CPU endianness
taking the unaligned source into account.
Side note: So far the register content is 0x0 on all mcp251xfd
compatible chips, and is only used for an informative printk.

dev_id
The device ID register is 32 bits wide. The driver uses incorrectly
the size of a pointer to a u32 to calculate the length of the SPI
transfer. This results in a read of 2 registers on 64 bit platforms.
This is no problem on the Linux side, as the RX buffer of the SPI
transfer is large enough. In the mpc251xfd chip this results in the
read of an undocumented register. So far no problems were observed.
Fix the length of the SPI transfer to read the device ID register
only.

In commit 169d00a25658 ("can: mcp251xfd: add TX IRQ coalescing
support") software based TX coalescing was added to the driver. The
key idea is to keep the TX complete IRQ disabled for some time after
processing it and re-enable later by a hrtimer. When bringing the
interface down, this timer has to be stopped.
Add the missing hrtimer_cancel() of the tx_irq_time hrtimer to
mcp251xfd_stop().

TBC register
The mcp251xfd compatible chips have an erratum ([1], [2]), where the
received CRC doesn't match the calculated CRC. In commit
c7eb923c3caf ("can: mcp251xfd: mcp251xfd_regmap_crc_read(): work
around broken CRC on TBC register") the following workaround was
implementierend.
- If a CRC read error on the TBC register is detected and the first
byte is 0x00 or 0x80, the most significant bit of the first byte is
flipped and the CRC is calculated again.
- If the CRC now matches, the _original_ data is passed to the reader.
For now we assume transferred data was OK.
New investigations and simulations indicate that the CRC send by the
device is calculated on correct data, and the data is incorrectly
received by the SPI host controller.
Use flipped instead of original data and update workaround description
in mcp251xfd_regmap_crc_read().

During a reset, there may have been transmits in flight that are no
longer valid and cannot be fulfilled. Resetting and clearing the
queues is insufficient; each skb also needs to be explicitly freed
so that upper levels are not left waiting for confirmation of a
transmit that will never happen. If this happens frequently enough,
the apparent backlog will cause TCP to begin "congestion control"
unnecessarily, culminating in permanently decreased throughput.

Received CAN frames are pushed to RX-offload together with a
timestamp. RX-offload is designed to handle overflows of the timestamp
correctly, if 32 bit timestamps are provided.
The timestamps of m_can core are only 16 bits wide. So this patch
shifts them to full 32 bit before passing them to RX-offload.

The gs_usb driver appears to suffer from a malady common to many USB
CAN adapter drivers in that it performs usb_alloc_coherent() to
allocate a number of USB request blocks (URBs) for RX, and then later
relies on usb_kill_anchored_urbs() to free them, but this doesn't
actually free them. As a result, this may be leaking DMA memory that's
been used by the driver.
This commit is an adaptation of the techniques found in the esd_usb2
driver where a similar design pattern led to a memory leak. It
explicitly frees the RX URBs and their DMA memory via a call to
usb_free_coherent(). Since the RX URBs were allocated in the
gs_can_open(), we remove them in gs_can_close() rather than in the
disconnect function as was done in esd_usb2.
For more information, see the 928150fad41b ("can: esd_usb2: fix memory
leak").

In commit d5f9023fa61e ("can: bcm: delay release of struct bcm_op
after synchronize_rcu()") Thadeu Lima de Souza Cascardo introduced two
synchronize_rcu() calls in bcm_release() (only once at socket close)
and in bcm_delete_rx_op() (called on removal of each single bcm_op).
Unfortunately this slow removal of the bcm_op's affects user space
applications like cansniffer where the modification of a filter
removes 2048 bcm_op's which blocks the cansniffer application for
40(!) seconds.
In commit 181d4447905d ("can: gw: use call_rcu() instead of costly
synchronize_rcu()") Eric Dumazet replaced the synchronize_rcu() calls
with several call_rcu()'s to safely remove the data structures after
the removal of CAN ID subscriptions with can_rx_unregister() calls.
This patch adopts Erics approach for the can-bcm which should be
applicable since the removal of tasklet_kill() in bcm_remove_op() and
the introduction of the HRTIMER_MODE_SOFT timer handling in Linux 5.4.

The USBH composed of EHCI and OHCI controllers needs the PHY clock to be
initialized first, before enabling (gating) them. The reverse is also
required when going to suspend.
So, add USBPHY clock as 1st entry in both controllers, so the USBPHY PLL
gets enabled 1st upon controller init. Upon suspend/resume, this also makes
the clock to be disabled/re-enabled in the correct order.
This fixes some IRQ storm conditions seen when going to low-power, due to
PHY PLL being disabled before all clocks are cleanly gated.

Fixes stm32mp15*-scmi DTS files introduced in [1] to also access PWR
regulators through SCMI service. This is needed since enabling secure
only access to RCC clock and reset controllers also enables secure
access only on PWR voltage regulators reg11, reg18 and usb33 hence
these must also be accessed through SCMI Voltage Domain protocol.
This change applies on commit [2] that already corrects issues from
commit [1].

Currently the implementation will split the PUD when a fallback is taken
inside the create_huge_pud function. This isn't where it should be done:
the splitting should be done in wp_huge_pud, just like it's done for PMDs.
Reason being that if a callback is taken during create, there is no PUD
yet so nothing to split, whereas if a fallback is taken when encountering
a write protection fault there is something to split.
It looks like this was the original intention with the commit where the
splitting was introduced, but somehow it got moved to the wrong place
between v1 and v2 of the patch series. Rebase mistake perhaps.

The subpage we calculate is an invalid pointer for device private pages,
because device private pages are mapped via non-present device private
entries, not ordinary present PTEs.
Let's just not compute broken pointers and fixup later. Move the proper
assignment of the correct subpage to the beginning of the function and
assert that we really only have a single page in our folio.
This currently results in a BUG when tying to compute anon_exclusive,
because:

Higher order allocations for vmemmap pages from buddy allocator must be
able to be treated as indepdenent small pages as they can be freed
individually by the caller. There is no problem for higher order vmemmap
pages allocated at boot time since each individual small page will be
initialized at boot time. However, it will be an issue for memory hotplug
case since those higher order vmemmap pages are allocated from buddy
allocator without initializing each individual small page's refcount. The
system will panic in put_page_testzero() when CONFIG_DEBUG_VM is enabled
if the vmemmap page is freed.

failures like:

When fallocate() is used on a shmem file, the pages we allocate can end up
with !PageUptodate.
Since UFFDIO_CONTINUE tries to find the existing page the user wants to
map with SGP_READ, we would fail to find such a page, since
shmem_getpage_gfp returns with a "NULL" pagep for SGP_READ if it discovers
!PageUptodate. As a result, UFFDIO_CONTINUE returns -EFAULT, as it would
do if the page wasn't found in the page cache at all.
This isn't the intended behavior. UFFDIO_CONTINUE is just trying to find
if a page exists, and doesn't care whether it still needs to be cleared or
not. So, instead of SGP_READ, pass in SGP_NOALLOC. This is the same,
except for one critical difference: in the !PageUptodate case, SGP_NOALLOC
will clear the page and then return it. With this change, UFFDIO_CONTINUE
works properly (succeeds) on a shmem file which has been fallocated, but
otherwise not modified.

Looking at the conditional lock acquire functions in the kernel due to
the new sparse support (see commit 4a557a5d1a61 "sparse: introduce
conditional lock acquire function attribute"), it became obvious that
the lockref code has a couple of them, but they don't match the usual
naming convention for the other ones, and their return value logic is
also reversed.
In the other very similar places, the naming pattern is '*_and_lock()'
(eg 'atomic_put_and_lock()' and 'refcount_dec_and_lock()'), and the
function returns true when the lock is taken.
The lockref code is superficially very similar to the refcount code,
only with the special "atomic wrt the embedded lock" semantics. But
instead of the '*_and_lock()' naming it uses '*_or_lock()'.
And instead of returning true in case it took the lock, it returns true
if it *didn't* take the lock.
Now, arguably the reflock code is quite logical: it really is a "either
decrement _or_ lock" kind of situation - and the return value is about
whether the operation succeeded without any special care needed.
So despite the similarities, the differences do make some sense, and
maybe it's not worth trying to unify the different conditional locking
primitives in this area.
But while looking at this all, it did become obvious that the
'lockref_get_or_lock()' function hasn't actually had any users for
almost a decade.
The only user it ever had was the shortlived 'd_rcu_to_refcount()'
function, and it got removed and replaced with 'lockref_get_not_dead()'
back in 2013 in commits 0d98439ea3c6 ("vfs: use lockred 'dead' flag to
mark unrecoverably dead dentries") and e5c832d55588 ("vfs: fix dentry
RCU to refcounting possibly sleeping dput()")
In fact, that single use was removed less than a week after the whole
function was introduced in commit b3abd80250c1 ("lockref: add
'lockref_get_or_lock() helper") so this function has been around for a
decade, but only had a user for six days.
Let's just put this mis-designed and unused function out of its misery.
We can think about the naming and semantic oddities of the remaining
'lockref_put_or_lock()' later, but at least that function has users.
And while the naming is different and the return value doesn't match,
that function matches the whole '{atomic,refcount}_dec_and_test()'
pattern much better (ie the magic happens when the count goes down to
zero, not when it is incremented from zero).

Qualcomm ARM64 DT fixes for v5.19
This removes duplicate includes in the sc7180-trogdor files, which
accidentally ended up disabling nodes intended to be enabled.
It corrects identifiers for CPU6/7 on MSM8994. On SM8450 the UFS node's
interconnects property is updated to match the #interconnect-cells,
avoiding sync_state issues and the GIC ITS is defined, to correct the
references from the PCIe nodes. On SDM845 the display subsystem's AHB
clock is corrected and on msm8992 devices, the supplies for lvs 1 and 2
are correctly specified.
Lastly, a welcome addition of Konrad as reviewer for the Qualcomm SoC.

The kernel tends to try to avoid conditional locking semantics because
it makes it harder to think about and statically check locking rules,
but we do have a few fundamental locking primitives that take locks
conditionally - most obviously the 'trylock' functions.
That has always been a problem for 'sparse' checking for locking
imbalance, and we've had a special '__cond_lock()' macro that we've used
to let sparse know how the locking works:
# define __cond_lock(x,c) ((c) ? ({ __acquire(x); 1; }) : 0)
so that you can then use this to tell sparse that (for example) the
spinlock trylock macro ends up acquiring the lock when it succeeds, but
not when it fails:
#define raw_spin_trylock(lock) __cond_lock(lock, _raw_spin_trylock(lock))
and then sparse can follow along the locking rules when you have code like
if (!spin_trylock(&dentry->d_lock))
return LRU_SKIP;
.. sparse sees that the lock is held here..
spin_unlock(&dentry->d_lock);
and sparse ends up happy about the lock contexts.
However, this '__cond_lock()' use does result in very ugly header files,
and requires you to basically wrap the real function with that macro
that uses '__cond_lock'. Which has made PeterZ NAK things that try to
fix sparse warnings over the years [1].
To solve this, there is now a very experimental patch to sparse that
basically does the exact same thing as '__cond_lock()' did, but using a
function attribute instead. That seems to make PeterZ happy [2].
Note that this does not replace existing use of '__cond_lock()', but
only exposes the new proposed attribute and uses it for the previously
unannotated 'refcount_dec_and_lock()' family of functions.
For existing sparse installations, this will make no difference (a
negative output context was ignored), but if you have the experimental
sparse patch it will make sparse now understand code that uses those
functions, the same way '__cond_lock()' makes sparse understand the very
similar 'atomic_dec_and_lock()' uses that have the old '__cond_lock()'
annotations.
Note that in some cases this will silence existing context imbalance
warnings. But in other cases it may end up exposing new sparse warnings
for code that sparse just didn't see the locking for at all before.
This is a trial, in other words. I'd expect that if it ends up being
successful, and new sparse releases end up having this new attribute,
we'll migrate the old-style '__cond_lock()' users to use the new-style
'__cond_acquires' function attribute.
The actual experimental sparse patch was posted in [3].

"This fixes some stalling problems and corrects the last of the
problems (I hope) observed during testing of the new atomic xattr
update feature.
- Fix statfs blocking on background inode gc workers
- Fix some broken inode lock assertion code
- Fix xattr leaf buffer leaks when cancelling a deferred xattr update
operation
- Clean up xattr recovery to make it easier to understand.
- Fix xattr leaf block verifiers tripping over empty blocks.
- Remove complicated and error prone xattr leaf block bholding mess.
- Fix a bug where an rt extent crossing EOF was treated as "posteof"
blocks and cleaned unnecessarily.
- Fix a UAF when log shutdown races with unmount"
* tag 'xfs-5.19-fixes-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
xfs: prevent a UAF when log IO errors race with unmount
xfs: dont treat rt extents beyond EOF as eofblocks to be cleared
xfs: don't hold xattr leaf buffers across transaction rolls
xfs: empty xattr leaf header blocks are not corruption
xfs: clean up the end of xfs_attri_item_recover
xfs: always free xattri_leaf_bp when cancelling a deferred op
xfs: use invalidate_lock to check the state of mmap_lock
xfs: factor out the common lock flags assert
xfs: introduce xfs_inodegc_push()
xfs: bound maximum wait time for inodegc work

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Insufficient validation of element datatype and length in
nft_setelem_parse_data(). At least commit 7d7402642eaf updates
maximum element data area up to 64 bytes when only 16 bytes
where supported at the time. Support for larger element size
came later in fdb9c405e35b though. Picking this older commit
as Fixes: tag to be safe than sorry.
2) Memleak in pipapo destroy path, reproducible when transaction
in aborted. This is already triggering in the existing netfilter
test infrastructure since more recent new tests are covering this
path.

New elements that reside in the clone are not released in case that the
transaction is aborted.

Add nft_set_pipapo_match_destroy() helper function to release the
elements in the lookup tables.
Stefano Brivio says: "We additionally look for elements pointers in the
cloned matching data if priv->dirty is set, because that means that
cloned data might point to additional elements we did not commit to the
working copy yet (such as the abort path case, but perhaps not limited
to it)."
