commit 3d1cf435e2 upstream.
If the device passed as the target (second argument) to
device_is_dependent() is not completely registered (that is, it has
been initialized, but not added yet), but the parent pointer of it
is set, it may be missing from the list of the parent's children
and device_for_each_child() called by device_is_dependent() cannot
be relied on to catch that dependency.
For this reason, modify device_is_dependent() to check the ancestors
of the target device by following its parent pointer in addition to
the device_for_each_child() walk.

commit 576667bad3 upstream.
Once the command ring doorbell is rung the xHC controller will parse all
command TRBs on the command ring that have the cycle bit set properly.
If the driver just started writing the next command TRB to the ring when
hardware finished the previous TRB, then HW might fetch an incomplete TRB
as long as its cycle bit set correctly.
A command TRB is 16 bytes (128 bits) long.
Driver writes the command TRB in four 32 bit chunks, with the chunk
containing the cycle bit last. This does however not guarantee that
chunks actually get written in that order.
This was detected in stress testing when canceling URBs with several
connected USB devices.
Two consecutive "Set TR Dequeue pointer" commands got queued right
after each other, and the second one was only partially written when
the controller parsed it, causing the dequeue pointer to be set
to bogus values. This was seen as error messages:
"Mismatch between completed Set TR Deq Ptr command & xHCI internal state"
Solution is to add a write memory barrier before writing the cycle bit.

commit 643a4df7fe upstream.
The system that use Synopsys USB host controllers goes to suspend
when using USB audio player. This causes the USB host controller
continuous send interrupt signal to system, When the number of
interrupts exceeds 100000, the system will forcibly close the
interrupts and output a calltrace error.
When the system goes to suspend, the last interrupt is reported to
the driver. At this time, the system has set the state to suspend.
This causes the last interrupt to not be processed by the system and
not clear the interrupt flag. This uncleared interrupt flag constantly
triggers new interrupt event. This causing the driver to receive more
than 100,000 interrupts, which causes the system to forcibly close the
interrupt report and report the calltrace error.
so, when the driver goes to sleep and changes the system state to
suspend, the interrupt flag needs to be cleared.

Commit c685af1108 ("serial: mvebu-uart: fix tx lost characters") fixed tx
lost characters at low baud rates but started causing tx lost characters
when kernel is going to power off or reboot.
TX_EMP tells us when transmit queue is empty therefore all characters were
transmitted. TX_RDY tells us when CPU can send a new character.
Therefore we need to use different check prior transmitting new character
and different check after all characters were sent.
This patch splits polling code into two functions: wait_for_xmitr() which
waits for TX_RDY and wait_for_xmite() which waits for TX_EMP.
When rebooting A3720 platform without this patch on UART is print only:

The irq_domain_trim_hierarchy() function doesn't consider the irq + ipi

[ Upstream commit 070222731b ]
THe HP Stream x360 Convertible PC 11 DSDT has the following VGBS function:
Method (VGBS, 0, Serialized)
{
If ((^^PCI0.LPCB.EC0.ROLS == Zero))
{
VBDS = Zero
}
Else
{
VBDS = Zero
}
Return (VBDS) /* \_SB_.VGBI.VBDS */
}
Which is obviously wrong, because it always returns 0 independent of the
2-in-1 being in laptop or tablet mode. This causes the intel-vbtn driver
to initially report SW_TABLET_MODE = 1 to userspace, which is known to
cause problems when the 2-in-1 is actually in laptop mode.
During earlier testing this turned out to not be a problem because the
2-in-1 would do a Notify(..., 0xCC) or Notify(..., 0xCD) soon after
the intel-vbtn driver loaded, correcting the SW_TABLET_MODE state.
Further testing however has shown that this Notify() soon after the
intel-vbtn driver loads, does not always happen. When the Notify
does not happen, then intel-vbtn reports SW_TABLET_MODE = 1 resulting in
a non-working touchpad.
IOW the tablet-mode reporting is not reliable on this device, so it
should be dropped from the allow-list, fixing the touchpad sometimes
not working.

Event Message: A PCI parity error was detected on a component at bus 0 device 5 function 0.
Severity: Critical
Message ID: PCI1308
The original code tried to handle the sense data pointer differently when

In my patch, I tried to ensure that the same value is used on both 32-bit
and 64-bit kernels, and picked what seemed to be the most sensible
combination, storing 32-bit addresses in the first four bytes (as 32-bit
kernels already did), and 64-bit addresses in eight consecutive bytes (as
64-bit kernels already did), but evidently this was incorrect.
Always storing the dma_addr_t pointer as 64-bit little-endian,
i.e. initializing the second four bytes to zero in case of 32-bit
addressing, apparently solved the problem for Phil, and is consistent with
what all 64-bit little-endian machines did before.
I also checked in the history that in previous versions of the code, the
pointer was always in the first four bytes without padding, and that
previous attempts to fix 64-bit user space, big-endian architectures and
64-bit DMA were clearly flawed and seem to have introduced made this worse.

[ Upstream commit 3499ba8198 ]
For a while, event channel notification via the PCI platform device
has been broken, because we attempt to communicate with xenstore before
we even have notifications working, with the xs_reset_watches() call
in xs_init().
We tend to get away with this on Xen versions below 4.0 because we avoid
calling xs_reset_watches() anyway, because xenstore might not cope with
reading a non-existent key. And newer Xen *does* have the vector
callback support, so we rarely fall back to INTX/GSI delivery.
To fix it, clean up a bit of the mess of xs_init() and xenbus_probe()
startup. Call xs_init() directly from xenbus_init() only in the !XS_HVM
case, deferring it to be called from xenbus_probe() in the XS_HVM case
instead.
Then fix up the invocation of xenbus_probe() to happen either from its
device_initcall if the callback is available early enough, or when the
callback is finally set up. This means that the hack of calling
xenbus_probe() from a workqueue after the first interrupt, or directly
from the PCI platform device setup, is no longer needed.

644bda6f34 ("dm table: fall back to getting device using name_to_dev_t()")
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.

- Arriving GRO skb (or GSO skb in a virtualised environment) that is

If so:
- Consume the SKB and its segments.

commit dcfea72e79 upstream.
As part of the continual effort to remove direct usage of skb->next and
skb->prev, this patch adds a helper for iterating through the
singly-linked variant of skb lists, which are used for lists of GSO
packet. The name "skb_list_..." has been chosen to match the existing
function, "kfree_skb_list, which also operates on these singly-linked
lists, and the "..._walk_safe" part is the same idiom as elsewhere in
the kernel.
This patch removes the helper from wireguard and puts it into
linux/skbuff.h, while making it a bit more robust for general usage. In
particular, parenthesis are added around the macro argument usage, and it
now accounts for trying to iterate through an already-null skb pointer,
which will simply run the iteration zero times. This latter enhancement
means it can be used to replace both do { ... } while and while (...)
open-coded idioms.
This should take care of these three possible usages, which match all
current methods of iterations.
skb_list_walk_safe(segs, skb, next) { ... }
skb_list_walk_safe(skb, skb, next) { ... }
skb_list_walk_safe(segs, skb, segs) { ... }

rxrpc_read() contains two consecutive loops. The first loop calculates the

the array. When there is an error in identifying the token in the first
loop, the token is skipped, no change is made to the toksizes[] array.
When the same error happens in the second loop, the token is not skipped.
This will cause the toksizes[] array to be out of step and will overrun
past the calculated sizes.
Fix this by making both loops log a message and return an error in this
case. This should only happen if a new token type is incompletely
implemented, so it should normally be impossible to trigger this.

[ Upstream commit 3226b158e6 ]
Both virtio net and napi_get_frags() allocate skbs
with a very small skb->head
While using page fragments instead of a kmalloc backed skb->head might give
a small performance improvement in some cases, there is a huge risk of
under estimating memory usage.
For both GOOD_COPY_LEN and GRO_MAX_HEAD, we can fit at least 32 allocations
per page (order-3 page in x86), or even 64 on PowerPC
We have been tracking OOM issues on GKE hosts hitting tcp_mem limits
but consuming far more memory for TCP buffers than instructed in tcp_mem[2]
Even if we force napi_alloc_skb() to only use order-0 pages, the issue
would still be there on arches with PAGE_SIZE >= 32768
This patch makes sure that small skb head are kmalloc backed, so that
other objects in the slab page can be reused instead of being held as long
as skbs are sitting in socket queues.
Note that we might in the future use the sk_buff napi cache,
instead of going through a more expensive __alloc_skb()
Another idea would be to use separate page sizes depending
on the allocated length (to never have more than 4 frags per page)
I would like to thank Greg Thelen for his precious help on this matter,
analysing crash dumps is always a time consuming task.
