[ Upstream commit 615d435400435876ac68c1de37e9526a9164eaec ]
Currently hda on tegra30 fails to open a stream with an input/output error.
For example:
speaker-test -Dhw:0,3 -c 2
speaker-test 1.2.2
Playback device is hw:0,3
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
0 - Front Left
Write error: -5,Input/output error
xrun_recovery failed: -5,Input/output error
Transfer failed: Input/output error
The tegra-hda device was introduced in tegra30 but only utilized in
tegra124 until recent chips. Tegra210/186 work only due to a hardware
change. For this reason it is unknown when this issue first manifested.
Discussions with the hardware team show this applies to all current tegra
chips. It has been resolved in the tegra234, which does not have hda
support at this time.
The explanation from the hardware team is this:
Below is the striping formula referenced from HD audio spec.
{ ((num_channels * bits_per_sample) / number of SDOs) >= 8 }
The current issue is seen because Tegra HW has a problem with boundary
condition (= 8) for striping. The reason why it is not seen on
Tegra210/Tegra186 is because it uses max 2SDO lines. Max SDO lines is
read from GCAP register.
For the given stream (channels = 2, bps = 16);
ratio = (channels * bps) / NSDO = 32 / NSDO;
On Tegra30, ratio = 32/4 = 8 (FAIL)
On Tegra210/186, ratio = 32/2 = 16 (PASS)
On Tegra194, ratio = 32/4 = 8 (FAIL) ==> Earlier workaround was
applied for it
If Tegra210/186 is forced to use 4SDO, it fails there as well. So the
behavior is consistent across all these chips.
Applying the fix in [1] universally resolves this issue on tegra30-hda.
Tested on the Ouya game console and the tf201 tablet.

The block layer code will split a large zeroout request into multiple bios
and if WRITE SAME is disabled because the storage device reports that it
does not support it (or support the length used), we can get an error
message from the block layer despite the setting of RQF_QUIET on the first
request. This is because more than one request may have already been
submitted.
Fix this by setting RQF_QUIET when BLK_STS_TARGET is returned to fail the
request early, we don't need to log a message because we did not actually
submit the command to the device, and the block layer code will handle the
error by submitting individual write bios.

Currently the kexec kernel can panic or hang due to 2 causes:
1) hv_cpu_die() is not called upon kexec, so the hypervisor corrupts the
old VP Assist Pages when the kexec kernel runs. The same issue is fixed
for hibernation in commit 421f090c81 ("x86/hyperv: Suspend/resume the
VP assist page for hibernation"). Now fix it for kexec.
2) hyperv_cleanup() is called too early. In the kexec path, the other CPUs
are stopped in hv_machine_shutdown() -> native_machine_shutdown(), so
between hv_kexec_handler() and native_machine_shutdown(), the other CPUs
can still try to access the hypercall page and cause panic. The workaround
"hv_hypercall_pg = NULL;" in hyperv_cleanup() is unreliabe. Move
hyperv_cleanup() to a better place.

Daire Byrne reports a ~50% aggregrate throughput regression on his
Linux NFS server after commit da1661b93b ("SUNRPC: Teach server to
use xprt_sock_sendmsg for socket sends"), which replaced
kernel_send_page() calls in NFSD's socket send path with calls to
sock_sendmsg() using iov_iter.
Investigation showed that tcp_sendmsg() was not using zero-copy to
send the xdr_buf's bvec pages, but instead was relying on memcpy.
This means copying every byte of a large NFS READ payload.
It looks like TLS sockets do indeed support a ->sendpage method,
so it's really not necessary to use xprt_sock_sendmsg() to support
TLS fully on the server. A mechanical reversion of da1661b93b is
not possible at this point, but we can re-implement the server's
TCP socket sendmsg path using kernel_sendpage().

commit 45db630e5f7ec83817c57c8ae387fe219bd42adf upstream.
Since we allow removing the timeline map at runtime, there is a risk
that rq->hwsp points into a stale page. To control that risk, we hold
the RCU read lock while reading *rq->hwsp, but we missed a couple of
important barriers. First, the unpinning / removal of the timeline map
must be after all RCU readers into that map are complete, i.e. after an
rcu barrier (in this case courtesy of call_rcu()). Secondly, we must
make sure that the rq->hwsp we are about to dereference under the RCU
lock is valid. In this case, we make the rq->hwsp pointer safe during
i915_request_retire() and so we know that rq->hwsp may become invalid
only after the request has been signaled. Therefore is the request is
not yet signaled when we acquire rq->hwsp under the RCU, we know that
rq->hwsp will remain valid for the duration of the RCU read lock.
This is a very small window that may lead to either considering the
request not completed (causing a delay until the request is checked
again, any wait for the request is not affected) or dereferencing an
invalid pointer.

Otherwise a malicious user could (ab)use the "recalculate" feature

while the device is already usable. When the system restarts before all
checksums have been calculated, the calculation continues where it was
interrupted even if the recalculate feature is not requested the next
time the dm device is set up.
Disable recalculating if we use internal_hash or journal_hash with a
key (e.g. HMAC) and we don't have the "legacy_recalculate" flag.
This may break activation of a volume, created by an older kernel,
that is not yet fully recalculated -- if this happens, the user should
add the "legacy_recalculate" flag to constructor parameters.

dm_get_dev_t() is just used to convert an arbitrary 'path' string
into a dev_t. It doesn't presume that the device is present; that
check will be done later, as the only caller is dm_get_device(),
which does a dm_get_table_device() later on, which will properly
open the device.
So if the path string already _is_ in major:minor representation
we can convert it directly, avoiding a recursion into the filesystem
to lookup the block device.
This avoids a hang in multipath_message() when the filesystem is
inaccessible.

RPMB ACM23 case, we need to set bit 31 to CMD23 argument, otherwise
RPMB write operation will return general fail.
However, no matter V4 is enabled or not, the dwcmshc's ARGUMENT2
register is 32-bit block count register which doesn't support stuff
bits of CMD23 argument. So let's handle this specific ACMD23 case.
From another side, this patch also prepare for future v4 enabling
for dwcmshc, because from the 4.10 spec, the ARGUMENT2 register is
redefined as 32bit block count which doesn't support stuff bits of
CMD23 argument.

commit b503087445ce7e45fabdee87ca9e460d5b5b5168 upstream.
If extended CSD was not available, the eMMC driver would incorrectly
set the block size to 0, as the data_sector_size field of ext_csd
was never initialized. This issue was exposed by commit 817046ecddbc
("block: Align max_hw_sectors to logical blocksize") which caused
max_sectors and max_hw_sectors to be set to 0 after setting the block
size to 0, resulting in a kernel panic in bio_split when attempting
to read from the device. Fix it by only reading the block size from
ext_csd if it is available.

commit 1e249cb5b7fc09ff216aa5a12f6c302e434e88f9 upstream.
When lazytime is enabled and an inode is being written due to its
in-memory updated timestamps having expired, either due to a sync() or
syncfs() system call or due to dirtytime_expire_interval having elapsed,
the VFS needs to inform the filesystem so that the filesystem can copy
the inode's timestamps out to the on-disk data structures.
This is done by __writeback_single_inode() calling
mark_inode_dirty_sync(), which then calls ->dirty_inode(I_DIRTY_SYNC).
However, this occurs after __writeback_single_inode() has already
cleared the dirty flags from ->i_state. This causes two bugs:
- mark_inode_dirty_sync() redirties the inode, causing it to remain
dirty. This wastefully causes the inode to be written twice. But
more importantly, it breaks cases where sync_filesystem() is expected
to clean dirty inodes. This includes the FS_IOC_REMOVE_ENCRYPTION_KEY
ioctl (as reported at
https://lore.kernel.org/r/20200306004555.GB225345@gmail.com), as well
as possibly filesystem freezing (freeze_super()).
- Since ->i_state doesn't contain I_DIRTY_TIME when ->dirty_inode() is
called from __writeback_single_inode() for lazytime expiration,
xfs_fs_dirty_inode() ignores the notification. (XFS only cares about
lazytime expirations, and it assumes that i_state will contain
I_DIRTY_TIME during those.) Therefore, lazy timestamps aren't
persisted by sync(), syncfs(), or dirtytime_expire_interval on XFS.
Fix this by moving the call to mark_inode_dirty_sync() to earlier in
__writeback_single_inode(), before the dirty flags are cleared from
i_state. This makes filesystems be properly notified of the timestamp
expiration, and it avoids incorrectly redirtying the inode.
This fixes xfstest generic/580 (which tests
FS_IOC_REMOVE_ENCRYPTION_KEY) when run on ext4 or f2fs with lazytime
enabled. It also fixes the new lazytime xfstest I've proposed, which
reproduces the above-mentioned XFS bug
(https://lore.kernel.org/r/20210105005818.92978-1-ebiggers@kernel.org).
Alternatively, we could call ->dirty_inode(I_DIRTY_SYNC) directly. But
due to the introduction of I_SYNC_QUEUED, mark_inode_dirty_sync() is the
right thing to do because mark_inode_dirty_sync() now knows not to move
the inode to a writeback list if it is currently queued for sync.

commit 518837e65068c385dddc0a87b3e577c8be7c13b1 upstream.
When an incremental send finds an extent that is shared, it checks which
file extent items in the range refer to that extent, and for those it
emits clone operations, while for others it emits regular write operations
to avoid corruption at the destination (as described and fixed by commit
d906d49fc5 ("Btrfs: send, fix file corruption due to incorrect cloning
operations")).
However when the root we are cloning from is the send root, we are cloning
from the inode currently being processed and the source file range has
several extent items that partially point to the desired extent, with an
offset smaller than the offset in the file extent item for the range we
want to clone into, it can cause the algorithm to issue a clone operation
that starts at the current eof of the file being processed in the receiver
side, in which case the receiver will fail, with EINVAL, when attempting
to execute the clone operation.
Example reproducer:
$ cat test-send-clone.sh
#!/bin/bash
DEV=/dev/sdi
MNT=/mnt/sdi
mkfs.btrfs -f $DEV >/dev/null
mount $DEV $MNT
# Create our test file with a single and large extent (1M) and with
# different content for different file ranges that will be reflinked
# later.

btrfs subvolume snapshot -r $MNT $MNT/snap1
btrfs send -f /tmp/snap1.send $MNT/snap1
# Now do a series of changes to our file such that we end up with
# different parts of the extent reflinked into different file offsets
# and we overwrite a large part of the extent too, so no file extent
# items refer to that part that was overwritten. This used to confuse
# the algorithm used by the kernel to figure out which file ranges to
# clone, making it attempt to clone from a source range starting at
# the current eof of the file, resulting in the receiver to fail since
# it is an invalid clone operation.

File digest in the new filesystem:

The clone operation is invalid because its source range starts at the
current eof of the file in the receiver, causing the receiver to get
an EINVAL error from the clone operation when attempting it.
For the example above, what happens is the following:
1) When processing the extent at file offset 1M, the algorithm checks that
the extent is shared and can be (fully or partially) found at file
offset 0.
At this point the file has a size (and eof) of 1M at the receiver;
2) It finds that our extent item at file offset 1M has a data offset of
64K and, since the file extent item at file offset 0 has a data offset
of 0, it issues a clone operation, from the same file and root, that
has a source range offset of 64K, destination offset of 1M and a length
of 64K, since the extent item at file offset 0 refers only to the first
128K of the shared extent.
After this clone operation, the file size (and eof) at the receiver is
increased from 1M to 1088K (1M + 64K);
3) Now there's still 896K (960K - 64K) of data left to clone or write, so
it checks for the next file extent item, which starts at file offset
128K. This file extent item has a data offset of 0 and a length of
256K, so a clone operation with a source range offset of 256K, a
destination offset of 1088K (1M + 64K) and length of 128K is issued.
After this operation the file size (and eof) at the receiver increases
from 1088K to 1216K (1088K + 128K);
4) Now there's still 768K (896K - 128K) of data left to clone or write, so
it checks for the next file extent item, located at file offset 384K.
This file extent item points to a different extent, not the one we want
to clone, with a length of 640K. So we issue a write operation into the
file range 1216K (1088K + 128K, end of the last clone operation), with
a length of 640K and with a data matching the one we can find for that
range in send root.
After this operation, the file size (and eof) at the receiver increases
from 1216K to 1856K (1216K + 640K);
5) Now there's still 128K (768K - 640K) of data left to clone or write, so
we look into the file extent item, which is for file offset 1M and it
points to the extent we want to clone, with a data offset of 64K and a
length of 960K.
However this matches the file offset we started with, the start of the
range to clone into. So we can't for sure find any file extent item
from here onwards with the rest of the data we want to clone, yet we
proceed and since the file extent item points to the shared extent,
with a data offset of 64K, we issue a clone operation with a source
range starting at file offset 1856K, which matches the file extent
item's offset, 1M, plus the amount of data cloned and written so far,
which is 64K (step 2) + 128K (step 3) + 640K (step 4). This clone
operation is invalid since the source range offset matches the current
eof of the file in the receiver. We should have stopped looking for
extents to clone at this point and instead fallback to write, which
would simply the contain the data in the file range from 1856K to
1856K + 128K.
So fix this by stopping the loop that looks for file ranges to clone at
clone_range() when we reach the current eof of the file being processed,
if we are cloning from the same file and using the send root as the clone
root. This ensures any data not yet cloned will be sent to the receiver
through a write operation.
A test case for fstests will follow soon.

This occurred because we freed our backref node in
btrfs_backref_error_cleanup(), but then tried to free it again in
btrfs_backref_release_cache(). This is because
btrfs_backref_release_cache() will cycle through all of the
cache->leaves nodes and free them up. However
btrfs_backref_error_cleanup() freed the backref node with
btrfs_backref_free_node(), which simply kfree()d the backref node
without unlinking it from the cache. Change this to a
btrfs_backref_drop_node(), which does the appropriate cleanup and
removes the node from the cache->leaves list, so when we go to free the
remaining cache we don't trip over items we've already dropped.

commit 004b8ae9e2de55ca7857ba8471209dd3179e088c upstream.
In commit d68b29584c25 ("dm crypt: use GFP_ATOMIC when allocating
crypto requests from softirq") code was incorrectly copy and pasted
from crypt_alloc_req_skcipher()'s crypto request allocation code to
crypt_alloc_req_aead(). It is OK from runtime perspective as both
simple encryption request pointer and AEAD request pointer are part of
a union, but may confuse code reviewers.

commit 67ea698c3950d10925be33c21ca49ffb64e21842 upstream.
It turned out that VIA codecs also mute the sound in the lowest mixer
level. Turn on the dac_min_mute flag to indicate the mute-as-minimum
in TLV like already done in Conexant and IDT codecs.

commit 495dc7637cb5ca8e39c46db818328410bb6e73a1 upstream.
The Acer Apire E5-575T laptop with codec ALC255 has a terrible
background noise comes from internal mic capture. And the jack
sensing dose not work for headset like some other Acer laptops.
This patch limits the internal mic boost on top of the existing
ALC255_FIXUP_ACER_MIC_NO_PRESENCE quirk for Acer Aspire E5-575T.

commit 217bfbb8b0bfa24619b11ab75c135fec99b99b20 upstream.
snd_seq_oss_synth_make_info() didn't check the error code from
snd_seq_oss_midi_make_info(), and this leads to the call of strlcpy()
with the uninitialized string as the source, which may lead to the
access over the limit.
Add the proper error check for avoiding the failure.

commit f419e5940f1d9892ea6f45acdaca572b9e73ff39 upstream.
Newer ideapads (e.g.: Yoga 14s, 720S 14) come with ELAN0634 touchpad do not
use EC to switch touchpad.
Reading VPCCMD_R_TOUCHPAD will return zero thus touchpad may be blocked
unexpectedly.
Writing VPCCMD_W_TOUCHPAD may cause a spurious key press.
Add has_touchpad_switch to workaround these machines.

commit 9bba96275576da0cf78ede62aeb2fc975ed8a32d upstream.
There are several reports about the tps6598x causing
interrupt flood on boards with the INT3515 ACPI node, which
then causes instability. There appears to be several
problems with the interrupt. One problem is that the
I2CSerialBus resources do not always map to the Interrupt
resource with the same index, but that is not the only
problem. We have not been able to come up with a solution
for all the issues, and because of that disabling the device
for now.
The PD controller on these platforms is autonomous, and the
purpose for the driver is primarily to supply status to the
userspace, so this will not affect any functionality.

commit bc1c2048abbe3c3074b4de91d213595c57741a6b upstream.
In order to not to start returning errors when new I2C_M flags are
added, change behavior to just ignore all flags that we don't know
about. This includes the I2C_M_DMA_SAFE flag that already exists but
causes -EINVAL to be returned for valid transactions.

commit 27b7c6e096264cc7b91bb80a4f65f8c0a66f079f upstream.
Upon a communication error, the interrupt handler can call
tegra_i2c_disable_packet_mode. This causes a sleeping poll to happen
unless the current transaction was marked atomic. Fix this by
making the poll happen atomically if we are in an IRQ.
This matches the behavior prior to the patch mentioned
in the Fixes tag.
