When flushing the serial port's buffer, uart_flush_buffer() calls
kfifo_reset() but if there is an outstanding DMA transfer then the
completion function will consume data from the kfifo via
uart_xmit_advance(), underflowing and leading to ongoing DMA as the
driver tries to transmit another 2^32 bytes.
This is readily reproduced with serial-generic and amidi sending even
short messages as closing the device on exit will wait for the fifo to
drain and in the underflow case amidi hangs for 30 seconds on exit in
tty_wait_until_sent(). A trace of that gives:
kworker/1:1-84 [001] 51.769423: bprint: serial8250_tx_dma: tx_size=3 fifo_len=3
amidi-763 [001] 51.769460: bprint: uart_flush_buffer: resetting fifo

irq/21-fe530000-76 [000] 51.804949: bprint: __dma_tx_complete: tx_size=4096
Since the port lock is held in when the kfifo is reset in
uart_flush_buffer() and in __dma_tx_complete(), adding a flush_buffer
hook to adjust the outstanding DMA byte count is sufficient to avoid the
kfifo underflow.

Mounting a filesystem that requires quota state changing will generate a
transaction.
We already check for a read-only device; we should do that for
norecovery too.
A quotacheck on a norecovery mount, and with the right log size, will cause
the mount process to hang on:

This is caused by a transaction running with bogus initialized head/tail
I initially hit this while running generic/050, with random log
sizes, but I managed to reproduce it reliably here with the steps
below:
mkfs.xfs -f -lsize=1025M -f -b size=4096 -m crc=1,reflink=1,rmapbt=1, -i
sparse=1 /dev/vdb2 > /dev/null
mount -o usrquota,grpquota,prjquota /dev/vdb2 /mnt
xfs_io -x -c 'shutdown -f' /mnt
umount /mnt
mount -o ro,norecovery,usrquota,grpquota,prjquota /dev/vdb2 /mnt
Last mount hangs up
As we add yet another validation if quota state is changing, this also
add a new helper named xfs_qm_validate_state_change(), factoring the
quota state changes out of xfs_qm_newmount() to reduce cluttering
within it.

I received a report from the release engineering side of the house that
xfs_scrub without the -n flag (aka fix it mode) would try to fix a

Source: https://blogs.oracle.com/linux/post/xfs-online-filesystem-repair
It is strange that xfs_scrub doesn't refuse to run, because the kernel
is supposed to return EOPNOTSUPP if we actually needed to run a repair,
and xfs_io's repair subcommand will perror that. And yet:
# xfs_io -x -c 'repair probe' /mnt/test
#
The first problem is commit dcb660f922 (4.15) which should have had
xchk_probe set the CORRUPT OFLAG so that any of the repair machinery
will get called at all.
It turns out that some refactoring that happened in the 6.6-6.8 era
broke the operation of this corner case. What we *really* want to
happen is that all the predicates that would steer xfs_scrub_metadata()
towards calling xrep_attempt() should function the same way that they do
when repair is compiled in; and then xrep_attempt gets to return the
fatal EOPNOTSUPP error code that causes the probe to fail.
Instead, commit 8336a64eb7 (6.6) started the failwhale swimming by
hoisting OFLAG checking logic into a helper whose non-repair stub always
returns false, causing scrub to return "repair not needed" when in fact
the repair is not supported. Prior to that commit, the oflag checking
that was open-coded in scrub.c worked correctly.
Similarly, in commit 4bdfd7d157 (6.8) we hoisted the IFLAG_REPAIR
and ALREADY_FIXED logic into a helper whose non-repair stub always
returns false, so we never enter the if test body that would have called
xrep_attempt, let alone fail to decode the OFLAGs correctly.
The final insult (yes, we're doing The Naked Gun now) is commit
48a72f6086 (6.8) in which we hoisted the "are we going to try a
repair?" predicate into yet another function with a non-repair stub
always returns false.
Fix xchk_probe to trigger xrep_probe if repair is enabled, or return
EOPNOTSUPP directly if it is not. For all the other scrub types, we
need to fix the header predicates so that the ->repair functions (which
are all xrep_notsupported) get called to return EOPNOTSUPP. Commit
48a72 is tagged here because the scrub code prior to LTS 6.12 are
incomplete and not worth patching.

As PD2.0 spec ("6.5.6.2 PSSourceOffTimer")，the PSSourceOffTimer is
used by the Policy Engine in Dual-Role Power device that is currently
acting as a Sink to timeout on a PS_RDY Message during a Power Role
Swap sequence. This condition leads to a Hard Reset for USB Type-A and

The role switch registration and set_role() can happen in parallel as they
are invoked independent of each other. There is a possibility that a driver
might spend significant amount of time in usb_role_switch_register() API
due to the presence of time intensive operations like component_add()
which operate under common mutex. This leads to a time window after
allocating the switch and before setting the registered flag where the set
role notifications are dropped. Below timeline summarizes this behavior

The behaviour of kthread_create_worker() was recently changed to align
with the one of kthread_create(). The kthread worker is created but not
awaken by default. This is to allow the use of kthread_affine_preferred()
and kthread_bind[_mask]() with kthread workers. In order to keep the
old behaviour and wake the kthread up, kthread_run_worker() must be
used. All the pre-existing users have been converted, except for UVC
that was introduced in the same merge window as the API change.
This results in hangs:

When usb_control_msg is used in the get_bMaxPacketSize0 function, the
USB pipe does not include the endpoint device number. This can cause
failures when a usb hub port is reinitialized after encountering a bad
cable connection. As a result, the system logs the following error
messages:
usb usb2-port1: cannot reset (err = -32)
usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
usb usb2-port1: attempt power cycle
usb 2-1: new high-speed USB device number 5 using ci_hdrc
usb 2-1: device descriptor read/8, error -71
The problem began after commit 85d07c5562 ("USB: core: Unite old
scheme and new scheme descriptor reads"). There
usb_get_device_descriptor was replaced with get_bMaxPacketSize0. Unlike
usb_get_device_descriptor, the get_bMaxPacketSize0 function uses the
macro usb_rcvaddr0pipe, which does not include the endpoint device
number. usb_get_device_descriptor, on the other hand, used the macro
usb_rcvctrlpipe, which includes the endpoint device number.
By modifying the get_bMaxPacketSize0 function to use usb_rcvctrlpipe
instead of usb_rcvaddr0pipe, the issue can be resolved. This change will
ensure that the endpoint device number is included in the USB pipe,
preventing reinitialization failures. If the endpoint has not set the
device number yet, it will still work because the device number is 0 in
udev.

There is a frequent timeout during controller enter/exit from halt state
after toggling the run_stop bit by SW. This timeout occurs when

when USB2 suspend PHY was disabled by passing the SNPS quirks

However, there is a requirement to enable USB2 suspend PHY by setting of
GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY bits when controller starts
in gadget or host mode results in the timeout issue.
This commit addresses this timeout issue by ensuring that the bits

The fastboot tool for communicating with Android bootloaders does not
work reliably with this device if USB 2 Link Power Management (LPM)
is enabled.
Various fastboot commands are affected, including the
following, which usually reproduces the problem within two tries:
fastboot getvar kernel
getvar:kernel FAILED (remote: 'GetVar Variable Not found')
This issue was hidden on many systems up until commit 63a1f84549
("xhci: stored cached port capability values in one place") as the xhci
driver failed to detect USB 2 LPM support if USB 3 ports were listed
before USB 2 ports in the "supported protocol capabilities".
Adding the quirk resolves the issue. No drawbacks are expected since
the device uses different USB product IDs outside of fastboot mode, and
since fastboot commands worked before, until LPM was enabled on the
tested system by the aforementioned commit.

of 1 byte (so the reassembled message is supposed to be 9 bytes long), and
we then receive a second fragment of size 9 bytes (which is not supposed to
happen), we currently wrongly bypass the fragment reassembly code but still
pass the pointer to the acm->notification_buffer to
acm_process_notification().
Make this less wrong by always going through fragment reassembly when we
expect more fragments.
Before this patch, receiving an overlong fragment could lead to `newctrl`
in acm_process_notification() being uninitialized data (instead of data
coming from the device).

If the first fragment is shorter than struct usb_cdc_notification, we can't
calculate an expected_size. Log an error and discard the notification
instead of reading lengths from memory outside the received data, which can
lead to memory corruption when the expected_size decreases between
fragments, causing `expected_size - acm->nb_index` to wrap.
This issue has been present since the beginning of git history; however,
it only leads to memory corruption since commit ea2583529c
("cdc-acm: reassemble fragmented notifications").
A mitigating factor is that acm_ctrl_irq() can only execute after userspace
has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will
do that automatically depending on the USB device's vendor/product IDs and
its other interfaces.

Some Renesas HCs require firmware upload to work, this is handled by the
xhci_pci_renesas driver. Other variants of those chips load firmware from
a SPI flash and are ready to work with xhci_pci alone.
A refactor merged in v6.12 broke the latter configuration so that users
are finding their hardware ignored by the normal driver and are forced to
enable the firmware loader which isn't really necessary on their systems.
Let xhci_pci work with those chips as before when the firmware loader is
disabled by kernel configuration.

This driver supports page faults on PCI RID since commit <9f831c16c69e>
("iommu/vt-d: Remove the pasid present check in prq_event_thread") by
allowing the reporting of page faults with the pasid_present field cleared
to the upper layer for further handling. The fundamental assumption here
is that the detach or replace operations act as a fence for page faults.
This implies that all pending page faults associated with a specific RID
or PASID are flushed when a domain is detached or replaced from a device
RID or PASID.
However, the intel_iommu_drain_pasid_prq() helper does not correctly
handle faults for RID. This leads to faults potentially remaining pending
in the iommu hardware queue even after the domain is detached, thereby
violating the aforementioned assumption.
Fix this issue by extending intel_iommu_drain_pasid_prq() to cover faults
for RID.

This is because in resume path, CNTRL[EPHEn] is not set. Fix this by
setting CNTRL[EPHEn] to 1 in resume path if EFR[EPHSUP] is set.
Note
May be better approach is to save the control register in suspend path
and restore it in resume path instead of trying to set indivisual

PIPEDSL is reading as 0 when in SRDENT(PSR1) or DEEP_SLEEP(PSR2). On
wake-up scanline counting starts from vblank_start - 1. We don't know if
wake-up is already ongoing when evasion starts. In worst case PIPEDSL could
start reading valid value right after checking the scanline. In this
scenario we wouldn't have enough time to write all registers. To tackle
this evade scanline 0 as well. As a drawback we have 1 frame delay in flip
when waking up.

- use intel_dsb_emit_wait_dsl

We have different approach on how flip is considered being complete. We are
waiting for vblank on DSB and generate interrupt when it happens and this
interrupt is considered as indication of completion -> we definitely do not
want to skip vblank wait.
Also not skipping scanline wait shouldn't cause any problems if we are in
DEEP_SLEEP PIPEDSL register is returning 0 -> evasion does nothing and if
we are not in DEEP_SLEEP evasion works same way as without PSR.

Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
Currently, DRM atomic uAPI allows only primary planes to be flipped
asynchronously. However, each driver might be able to perform async
flips in other different plane types. To enable drivers to set their own
restrictions on which type of plane they can or cannot flip, use the
existing atomic_async_check() from struct drm_plane_helper_funcs to
enhance this flexibility, thus allowing different plane types to be able
to do async flips as well.
Create a new parameter for the atomic_async_check(), `bool flip`. This
parameter is used to distinguish when this function is being called from
a plane update from a full page flip.
In order to prevent regressions and such, we keep the current policy: we
skip the driver check for the primary plane, because it is always
allowed to do async flips on it.
