[ Upstream commit e51d8d3ea3 ]
When sensor discovery fails, this means that the system doesn't have
any sensors connected and a user should only be notified at most one time.
A message is already displayed at WARN level of "failed to discover,
sensors not enabled". It's pointless to show that the client init failed
at ERR level for the same condition.
Check the return code and don't display this message in those conditions.

[ Upstream commit c31b14d86d ]
In case push_rcu() and related functions are buggy, there's a
WARN_ON(len >= 128), which the selftest tries to hit by being tricky. In
case it is hit, we shouldn't corrupt the kernel's stack, though;
otherwise it may be hard to even receive the report that it's buggy. So
conditionalize the stack write based on that WARN_ON()'s return value.
Note that this never *actually* happens anyway. The WARN_ON() in the
first place is bounded by IS_ENABLED(DEBUG), and isn't expected to ever
actually hit. This is just a debugging sanity check.
Additionally, hoist the constant 128 into a named enum,
MAX_ALLOWEDIPS_BITS, so that it's clear why this value is chosen.

[ Upstream commit 151c8e499f ]
Using msleep() is problematic because it's compared against
ratelimiter.c's ktime_get_coarse_boottime_ns(), which means on systems
with slow jiffies (such as UML's forced HZ=100), the result is
inaccurate. So switch to using schedule_hrtimeout().
However, hrtimer gives us access only to the traditional posix timers,
and none of the _COARSE variants. So now, rather than being too
imprecise like jiffies, it's too precise.
One solution would be to give it a large "range" value, but this will
still fire early on a loaded system. A better solution is to align the
timeout to the actual coarse timer, and then round up to the nearest
tick, plus change.
So add the timeout to the current coarse time, and then
schedule_hrtimer() until the absolute computed time.
This should hopefully reduce flakes in CI as well. Note that we keep the
retry loop in case the entire function is running behind, because the
test could still be scheduled out, by either the kernel or by the
hypervisor's kernel, in which case restarting the test and hoping to not
be scheduled out still helps.

commit 7da17624e7
nt: usb: USB_RTL8153_ECM should not default to y
In general, device drivers should not be enabled by default.
which basically broke the commit it claimed to fix, ie:
commit 657bc1d10b
r8153_ecm: avoid to be prior to r8152 driver
Avoid r8153_ecm is compiled as built-in, if r8152 driver is compiled
as modules. Otherwise, the r8153_ecm would be used, even though the
device is supported by r8152 driver.
this commit amounted to:
drivers/net/usb/Kconfig:
+config USB_RTL8153_ECM
+ tristate "RTL8153 ECM support"
+ depends on USB_NET_CDCETHER && (USB_RTL8152 || USB_RTL8152=n)
+ default y
+ help
+ This option supports ECM mode for RTL8153 ethernet adapter, when
+ CONFIG_USB_RTL8152 is not set, or the RTL8153 device is not
+ supported by r8152 driver.
drivers/net/usb/Makefile:
-obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o r8153_ecm.o
+obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o
+obj-$(CONFIG_USB_RTL8153_ECM) += r8153_ecm.o
And as can be seen it pulls a piece of the cdc_ether driver out into
a separate config option to be able to make this piece modular in case
cdc_ether is builtin, while r8152 is modular.
While in general, device drivers should indeed not be enabled by default:
this isn't a device driver per say, but rather this is support code for
the CDCETHER (ECM) driver, and should thus be enabled if it is enabled.

As part of FIB offload simulation, netdevsim stores IPv4 and IPv6 routes
and holds a reference on FIB info structures that in turn hold a
reference on the associated nexthop device(s).
In the unlikely case where we are unable to allocate memory to process a
route deletion request, netdevsim will not release the reference from
the associated FIB info structure, thereby preventing the associated
nexthop device(s) from ever being removed [1].
Fix this by scheduling a work item that will flush netdevsim's FIB table
upon route deletion failure. This will cause netdevsim to release its
reference from all the FIB info structures in its table.

The commit 3c82a21f43 ("net: allow binding socket in a VRF when
there's an unbound socket") changed the inet socket lookup to avoid
packets in a VRF from matching an unbound socket. This is to ensure the
necessary isolation between the default and other VRFs for routing and
forwarding. VRF-unaware processes running in the default VRF cannot
access another VRF and have to be run with 'ip vrf exec <vrf>'. This is
to be expected with tcp_l3mdev_accept disabled, but could be reallowed
when this sysctl option is enabled. So instead of directly checking dif
and sdif in inet[6]_match, here call inet_sk_bound_dev_eq(). This
allows a match on unbound socket for non-zero sdif i.e. for packets in
a VRF, if tcp_l3mdev_accept is enabled.

[ Upstream commit 9fdf6d97f0 ]
SMBus packet error checking (PEC) is implemented by appending one
additional byte of checksum data at the end of the message. This provides
additional protection and allows to detect data corruption on the I2C bus.
SMBus block reads support variable length reads. The first byte in the read
message is the number of available data bytes.
The combination of PEC and block read is currently not supported by the
Cadence I2C driver.
* When PEC is enabled the maximum transfer length for block reads
increases from 33 to 34 bytes.
* The I2C core smbus emulation layer relies on the driver updating the
`i2c_msg` `len` field with the number of received bytes. The updated
length is used when checking the PEC.
Add support to the Cadence I2C driver for handling SMBus block reads with
PEC. To determine the maximum transfer length uses the initial `len` value
of the `i2c_msg`. When PEC is enabled this will be 2, when it is disabled
it will be 1.
Once a read transfer is done also increment the `len` field by the amount
of received data bytes.
This change has been tested with a UCM90320 PMBus power monitor, which
requires block reads to access certain data fields, but also has PEC
enabled by default.

[ Upstream commit 9393761aec ]
When the post-processor hardware block is enabled, the driver
allocates an internal queue of buffers for the decoder enginer,
and uses the vb2 queue for the post-processor engine.
For instance, on a G1 core, the decoder engine produces NV12 buffers
and the post-processor engine can produce YUY2 buffers. The decoder
engine expects motion vectors to be appended to the NV12 buffers,
but this is only required for CODECs that need motion vectors,
such as H.264.
Fix the post-processor logic accordingly.

[ Upstream commit 104a70e1d0 ]
Bit 21 in register 0x24 (slice header info 1) actually represents
negated version of low delay flag. This can be seen in vendor Cedar
library source code. While this flag is not part of the standard, it can
be found in reference HEVC implementation.
Fix macro name and change it to flag.

[ Upstream commit 97ef77c52b ]
The original direct splicing mechanism from Jens required the input to
be a regular file because it was avoiding the special socket case. It
also recognized blkdevs as being close enough to a regular file. But it
forgot about chardevs, which behave the same way and work fine here.
This is an okayish heuristic, but it doesn't totally work. For example,
a few chardevs should be spliceable here. And a few regular files
shouldn't. This patch fixes this by instead checking whether FMODE_LSEEK
is set, which represents decently enough what we need rewinding for when
splicing to internal pipes.
