[ Upstream commit 50ac7479846053ca8054be833c1594e64de496bb ]
The userspace utility "driverctl" can be used to change/override the
system's default driver choices. This is useful in some situations
(buggy driver, old driver missing a device ID, trying a workaround,
etc.) where the user needs to load a different driver.
However, this is also prone to user error, where a driver is mapped
to a device it's not designed to drive. For example, if the ice driver
is mapped to driver iavf devices, the ice driver crashes.
Add a check to return an error if the ice driver is being used to
probe a virtual function.

[ Upstream commit 2459dcb96bcba94c08d6861f8a050185ff301672 ]
IFLA_IFNAME is nul-term string which means that IFLA_IFNAME buffer can be
larger than length of string which contains.
Function __rtnl_newlink() generates new own ifname if either IFLA_IFNAME
was not specified at all or userspace passed empty nul-term string.
It is expected that if userspace does not specify ifname for new ppp netdev
then kernel generates one in format "ppp<id>" where id matches to the ppp
unit id which can be later obtained by PPPIOCGUNIT ioctl.
And it works in this way if IFLA_IFNAME is not specified at all. But it
does not work when IFLA_IFNAME is specified with empty string.
So fix this logic also for empty IFLA_IFNAME in ppp_nl_newlink() function
and correctly generates ifname based on ppp unit identifier if userspace
did not provided preferred ifname.
Without this patch when IFLA_IFNAME was specified with empty string then
kernel created a new ppp interface in format "ppp<id>" but id did not
match ppp unit id returned by PPPIOCGUNIT ioctl. In this case id was some
number generated by __rtnl_newlink() function.

[ Upstream commit 2383cb9497d113360137a2be308b390faa80632d ]
Commit a5e63c7d38d5 "net: phy: micrel: Fix detection of ksz87xx
switch" broke link detection on the external ports of the KSZ8795.
The previously unused phy_driver structure for these devices specifies
config_aneg and read_status functions that appear to be designed for a
fixed link and do not work with the embedded PHYs in the KSZ8795.
Delete the use of these functions in favour of the generic PHY
implementations which were used previously.

gpio-lookup tables
[ Upstream commit 9d7b132e62e41b7d49bf157aeaf9147c27492e0f ]
The gpiod_lookup_table.table passed to gpiod_add_lookup_table() must
be terminated with an empty entry, add this.
Note we have likely been getting away with this not being present because
the GPIO lookup code first matches on the dev_id, causing most lookups to
skip checking the table and the lookups which do check the table will
find a matching entry before reaching the end. With that said, terminating
these tables properly still is obviously the correct thing to do.

[ Upstream commit 704e624f7b3e8a4fc1ce43fb564746d1d07b20c0 ]
On s390, the following build warning occurs:
drivers/net/ethernet/marvell/mvpp2/mvpp2.h:844:2: warning: overflow in
conversion from 'long unsigned int' to 'int' changes value from
'18446744073709551584' to '-32' [-Woverflow]
844 | ((total_size) - MVPP2_SKB_HEADROOM - MVPP2_SKB_SHINFO_SIZE)
This happens because MVPP2_SKB_SHINFO_SIZE, which is 320 bytes (which is
already 64-byte aligned) on some architectures, actually gets ALIGN'd up
to 512 bytes in the s390 case.
So then, when this is invoked:
MVPP2_RX_MAX_PKT_SIZE(MVPP2_BM_SHORT_FRAME_SIZE)
...that turns into:
704 - 224 - 512 == -32
...which is not a good frame size to end up with! The warning above is a
bit lucky: it notices a signed/unsigned bad behavior here, which leads
to the real problem of a frame that is too short for its contents.
Increase MVPP2_BM_SHORT_FRAME_SIZE by 32 (from 704 to 736), which is
just exactly big enough. (The other values can't readily be changed
without causing a lot of other problems.)

The software mapping for GPIO, which initially comes from Microsoft,
is subject to change by respective Windows and firmware developers.
Due to the above the driver had been written and published way ahead
of the schedule, and thus the numbering schema used in it is outdated.

[ Upstream commit 798a315fc359aa6dbe48e09d802aa59b7e158ffc ]
Some pin doesn't support PUPD register, if it fails and fallbacks with
bias_set_combo case, it will call mtk_pinconf_bias_set_pupd_r1_r0() to
modify the PUPD pin again.
Since the general bias set are either PU/PD or PULLSEL/PULLEN, try
bias_set or bias_set_rev1 for the other fallback case. If the pin
doesn't support neither PU/PD nor PULLSEL/PULLEN, it will return
-ENOTSUPP.

commit d9cee9f85b22fab88d2b76d2e92b18e3d0e6aa8c upstream.
There are a few scenarios where init_active_labels() can return without
registering deactivate_labels() to run when the region is disabled. In
particular label error injection creates scenarios where a DIMM is
disabled, but labels on other DIMMs in the region become activated.
Arrange for init_active_labels() to always register deactivate_labels().

commit b93dfa6bda4d4e88e5386490f2b277a26958f9d3 upstream.
Fix the NFIT parsing code to treat a 0 index in a SPA Range Structure as
a special case and not match Region Mapping Structures that use 0 to
indicate that they are not mapped. Without this fix some platform BIOS
descriptions of "virtual disk" ranges do not result in the pmem driver
attaching to the range.
Details:
In addition to typical persistent memory ranges, the ACPI NFIT may also
convey "virtual" ranges. These ranges are indicated by a UUID in the SPA
Range Structure of UUID_VOLATILE_VIRTUAL_DISK, UUID_VOLATILE_VIRTUAL_CD,
UUID_PERSISTENT_VIRTUAL_DISK, or UUID_PERSISTENT_VIRTUAL_CD. The
critical difference between virtual ranges and UUID_PERSISTENT_MEMORY,
is that virtual do not support associations with Region Mapping
Structures. For this reason the "index" value of virtual SPA Range
Structures is allowed to be 0. If a platform BIOS decides to represent
NVDIMMs with disconnected "Region Mapping Structures" (range-index ==
0), the kernel may falsely associate them with standalone ranges where
the "SPA Range Structure Index" is also zero. When this happens the
driver may falsely require labels where "virtual disks" are expected to
be label-less. I.e. "label-less" is where the namespace-range ==
region-range and the pmem driver attaches with no user action to create
a namespace.

commit acc68b8d2a1196c4db806947606f162dbeed2274 upstream.
The CPSW switchdev driver inherited fix from commit 9421c9015047 ("net:
ethernet: ti: cpsw: fix min eth packet size") which changes min TX packet
size to 64bytes (VLAN_ETH_ZLEN, excluding ETH_FCS). It was done to fix HW
packed drop issue when packets are sent from Host to the port with PVID and
un-tagging enabled. Unfortunately this breaks some other non-switch
specific use-cases, like:
- [1] CPSW port as DSA CPU port with DSA-tag applied at the end of the
packet
- [2] Some industrial protocols, which expects min TX packet size 60Bytes
(excluding FCS).
Fix it by configuring min TX packet size depending on driver mode
- 60Bytes (ETH_ZLEN) for multi mac (dual-mac) mode
- 64Bytes (VLAN_ETH_ZLEN) for switch mode
and update it during driver mode change and annotate with
READ_ONCE()/WRITE_ONCE() as it can be read by napi while writing.

commit 86ff25ed6cd8240d18df58930bd8848b19fce308 upstream.
If an i2c driver happens to not provide the full amount of data that a
user asks for, it is possible that some uninitialized data could be sent
to userspace. While all in-kernel drivers look to be safe, just be sure
by initializing the buffer to zero before it is passed to the i2c driver
so that any future drivers will not have this issue.
Also properly copy the amount of data recvieved to the userspace buffer,
as pointed out by Dan Carpenter.

commit 5afc1540f13804a31bb704b763308e17688369c5 upstream.
Currently the for-loop that scans for the optimial adc_period iterates
through all the possible adc_period levels because the exit logic in
the loop is inverted. I believe the comparison should be swapped and
the continue replaced with a break to exit the loop at the correct
point.

commit 84edec86f449adea9ee0b4912a79ab8d9d65abb7 upstream.
The datasheets have the following note for the conversion time
specification: "This parameter is specified by design and/or
characterization and it is not tested in production."
Parts have been seen that require more time to do 14-bit conversions for
the relative humidity channel. The result is ENXIO due to the address
phase of a transfer not getting an ACK.
Delay an additional 1 ms per conversion to allow for additional margin.

commit 9898cb24e454602beb6e17bacf9f97b26c85c955 upstream.
The ADS7950 requires that CS is deasserted after each SPI word. Before
commit e2540da86ef8 ("iio: adc: ti-ads7950: use SPI_CS_WORD to reduce
CPU usage") the driver used a message with one spi transfer per channel
where each but the last one had .cs_change set to enforce a CS toggle.
This was wrongly translated into a message with a single transfer and
.cs_change set which results in a CS toggle after each word but the
last which corrupts the first adc conversion of all readouts after the
first readout.

commit 3125f26c514826077f2a4490b75e9b1c7a644c42 upstream.
When registering new ppp interface via PPPIOCNEWUNIT ioctl then kernel has
to choose interface name as this ioctl API does not support specifying it.
Kernel in this case register new interface with name "ppp<id>" where <id>
is the ppp unit id, which can be obtained via PPPIOCGUNIT ioctl. This
applies also in the case when registering new ppp interface via rtnl
without supplying IFLA_IFNAME.
PPPIOCNEWUNIT ioctl allows to specify own ppp unit id which will kernel
assign to ppp interface, in case this ppp id is not already used by other
ppp interface.
In case user does not specify ppp unit id then kernel choose the first free
ppp unit id. This applies also for case when creating ppp interface via
rtnl method as it does not provide a way for specifying own ppp unit id.
If some network interface (does not have to be ppp) has name "ppp<id>"
with this first free ppp id then PPPIOCNEWUNIT ioctl or rtnl call fails.
And registering new ppp interface is not possible anymore, until interface
which holds conflicting name is renamed. Or when using rtnl method with
custom interface name in IFLA_IFNAME.
As list of allocated / used ppp unit ids is not possible to retrieve from
kernel to userspace, userspace has no idea what happens nor which interface
is doing this conflict.
So change the algorithm how ppp unit id is generated. And choose the first
number which is not neither used as ppp unit id nor in some network
interface with pattern "ppp<id>".
This issue can be simply reproduced by following pppd call when there is no
ppp interface registered and also no interface with name pattern "ppp<id>":
pppd ifname ppp1 +ipv6 noip noauth nolock local nodetach pty "pppd +ipv6 noip noauth nolock local nodetach notty"
Or by creating the one ppp interface (which gets assigned ppp unit id 0),
renaming it to "ppp1" and then trying to create a new ppp interface (which
will always fails as next free ppp unit id is 1, but network interface with
name "ppp1" exists).
This patch fixes above described issue by generating new and new ppp unit
id until some non-conflicting id with network interfaces is generated.

commit 26b75952ca0b8b4b3050adb9582c8e2f44d49687 upstream.
Kunpeng920's EHCI controller does not have SBRN register.
Reading the SBRN register when the controller driver is
initialized will get 0.
When rebooting the EHCI driver, ehci_shutdown() will be called.
if the sbrn flag is 0, ehci_shutdown() will return directly.
The sbrn flag being 0 will cause the EHCI interrupt signal to
not be turned off after reboot. this interrupt that is not closed
will cause an exception to the device sharing the interrupt.
Therefore, the EHCI controller of Kunpeng920 needs to skip
the read operation of the SBRN register.

[ Upstream commit 914ab19e471d8fb535ed50dff108b0a615f3c2d8 ]
Implement a .shutdown hook that will be called during a kexec operation
so that the TEE shared memory, session, and context that were set up
during .probe can be properly freed/closed.
Additionally, don't use dma-buf backed shared memory for the
fw_shm_pool. dma-buf backed shared memory cannot be reliably freed and
unregistered during a kexec operation even when tee_shm_free() is called
on the shm from a .shutdown hook. The problem occurs because
dma_buf_put() calls fput() which then uses task_work_add(), with the
TWA_RESUME parameter, to queue tee_shm_release() to be called before the
current task returns to user mode. However, the current task never
returns to user mode before the kexec completes so the memory is never
freed nor unregistered.
Use tee_shm_alloc_kernel_buf() to avoid dma-buf backed shared memory
allocation so that tee_shm_free() can directly call tee_shm_release().
This will ensure that the shm can be freed and unregistered during a
kexec operation.

[ Upstream commit 376e4199e327a5cf29b8ec8fb0f64f3d8b429819 ]
Currently TEE_SHM_DMA_BUF flag has been inappropriately used to not
register shared memory allocated for private usage by underlying TEE
driver: OP-TEE in this case. So rather add a new flag as TEE_SHM_PRIV
that can be utilized by underlying TEE drivers for private allocation
and usage of shared memory.
With this corrected, allow tee_shm_alloc_kernel_buf() to allocate a
shared memory region without the backing of dma-buf.

drm/amd/display: Only set default brightness for OLED
[Why]
We used to unconditionally set backlight path as AUX for panels capable
of backlight adjustment via DPCD in set default brightness.
[How]
This should be limited to OLED panel only since we control backlight via
PWM path for SDR mode in LCD HDR panel.

has used these since the start, so for the moment, let's only fix
the warning.

commit 9c9c6d0ab08acfe41c9f7efa72c4ad3f133a266b upstream.
The register offset for SFC_DONE was missing a '0' at the end, causing
us to read from a non-existent register address. We only use this
register in error state dumps so the mistake hasn't caused any real
problems, but fixing it will hopefully make the error state dumps a bit
more useful for debugging.

commit ce5a595744126be4f1327e29e3c5ae9aac6b38d5 upstream.
We currently only enforce BW floors for a subset of nodes in a path.
All BCMs that need updating are queued in the pre_aggregate/aggregate
phase. The first set() commits all queued BCMs and subsequent set()
calls short-circuit without committing anything. Since the floor BW
isn't set in sum_avg/max_peak until set(), then some BCMs are committed
before their associated nodes reflect the floor.
Set the floor as each node is being aggregated. This ensures that all
all relevant floors are set before the BCMs are committed.

commit 73606ba9242f8e32023699b500b7922b4cf2993c upstream.
The pre_aggregate callback isn't called in all cases before calling
aggregate. Add the missing calls so providers can rely on consistent
framework behavior.

commit 456a9dace42ecfcec7ce6e17c18d1985d628dcd0 upstream.
The initial BW values may be used by providers to enforce floors. Zero
these values after sync-state so that providers know when to stop
enforcing them.

commit 8311ee2164c5cd1b63a601ea366f540eae89f10e upstream.
In meson_spicc_probe, the error handling code needs to clean up master
by calling spi_master_put, but the remove function does not have this
function call. This will lead to memory leak of spicc->master.
