commit d710359c0b445e8c03e24f19ae2fb79ce7282260 upstream.
IIO trigger interface function iio_trigger_get() should be called after
iio_trigger_register() (or its devm analogue) strictly, because of
iio_trigger_get() acquires module refcnt based on the trigger->owner
pointer, which is initialized inside iio_trigger_register() to
THIS_MODULE.
If this call order is wrong, the next iio_trigger_put() (from sysfs
callback or "delete module" path) will dereference "default" module
refcnt, which is incorrect behaviour.

The 0 value used for INV_CHIP_ICM42600 was not working since the
match in i2c/spi was checking against NULL value.
To keep this check, add a first INV_CHIP_INVALID 0 value as safe

commit 90bc2af24638659da56397ff835f3c95a948f991 upstream.
Re-reading a recently merged fix to the raw_gadget driver showed that
it inadvertently introduced a double-free bug in a failure pathway.
If raw_ioctl_init() encounters an error after the driver ID number has
been allocated, it deallocates the ID number before returning. But
when dev_free() runs later on, it will then try to deallocate the ID
number a second time.
Closely related to this issue is another error in the recent fix: The
ID number is stored in the raw_dev structure before the code checks to
see whether the structure has already been initialized, in which case
the new ID number would overwrite the earlier value.
The solution to both bugs is to keep the new ID number in a local
variable, and store it in the raw_dev structure only after the check
for prior initialization. No errors can occur after that point, so
the double-free will never happen.

[ Upstream commit a2b1a5d40bd12b44322c2ccd40bb0ec1699708b6 ]
As reported by Yuming, currently tc always show a latency of UINT_MAX
for netem Qdisc's on 32-bit platforms:
$ tc qdisc add dev dummy0 root netem latency 100ms
$ tc qdisc show dev dummy0
qdisc netem 8001: root refcnt 2 limit 1000 delay 275s 275s
^^^^^^^^^^^^^^^^
Let us take a closer look at netem_dump():
qopt.latency = min_t(psched_tdiff_t, PSCHED_NS2TICKS(q->latency,
UINT_MAX);
qopt.latency is __u32, psched_tdiff_t is signed long,
(psched_tdiff_t)(UINT_MAX) is negative for 32-bit platforms, so
qopt.latency is always UINT_MAX.
Fix it by using psched_time_t (u64) instead.
Note: confusingly, users have two ways to specify 'latency':
1. normally, via '__u32 latency' in struct tc_netem_qopt;
2. via the TCA_NETEM_LATENCY64 attribute, which is s64.
For the second case, theoretically 'latency' could be negative. This
patch ignores that corner case, since it is broken (i.e. assigning a
negative s64 to __u32) anyways, and should be handled separately.
Thanks Ted Lin for the analysis [1] .

but it's more easily observable with discards (fstrim).
The device gets to a state that is also not possible to use

Booting with nvme_core.default_ps_max_latency=0 solves the issue.

commit 534d2eaf1970274150596fdd2bf552721e65d6b2 upstream.
It used to be that mix_interrupt_randomness() would credit 1 bit each
time it ran, and so add_interrupt_randomness() would schedule mix() to
run every 64 interrupts, a fairly arbitrary number, but nonetheless
considered to be a decent enough conservative estimate.
Since e3e33fc2ea7f ("random: do not use input pool from hard IRQs"),
mix() is now able to credit multiple bits, depending on the number of
calls to add(). This was done for reasons separate from this commit, but
it has the nice side effect of enabling this patch to schedule mix()
less often.
Currently the rules are:
a) Credit 1 bit for every 64 calls to add().
b) Schedule mix() once a second that add() is called.
c) Schedule mix() once every 64 calls to add().
Rules (a) and (c) no longer need to be coupled. It's still important to
have _some_ value in (c), so that we don't "over-saturate" the fast
pool, but the once per second we get from rule (b) is a plenty enough
baseline. So, by increasing the 64 in rule (c) to something larger, we
avoid calling queue_work_on() as frequently during irq storms.
This commit changes that 64 in rule (c) to be 1024, which means we
schedule mix() 16 times less often. And it does *not* need to change the
64 in rule (a).
Fixes: 58340f8e952b ("random: defer fast pool mixing to worker")

commit 7bc08056a6dabc3a1442216daf527edf61ac24b6 upstream.
Add a special case to block_rtas_call() to allow the ibm,platform-dump RTAS
call through the RTAS filter if the buffer address is 0.
According to PAPR, ibm,platform-dump is called with a null buffer address
to notify the platform firmware that processing of a particular dump is
finished.
Without this, on a pseries machine with CONFIG_PPC_RTAS_FILTER enabled, an
application such as rtas_errd that is attempting to retrieve a dump will
encounter an error at the end of the retrieval process.

Add usb product id of the Quectel RM500K module.
RM500K provides 2 mandatory interfaces to Linux host after enumeration.
- /dev/ttyUSB5: this is a serial interface for control path. User needs
to write AT commands to this device node to query status, set APN,
set PIN code, and enable/disable the data connection to 5G network.
- ethX: this is the data path provided as a RNDIS devices. After the
data connection has been established, Linux host can access 5G data
network via this interface.

[ Upstream commit 8af52fe9fd3bf5e7478da99193c0632276e1dfce ]
The following sequence currently causes a driver bug warning
when using virtio_net:
# ip link set eth0 up
# echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem)
<resume>
# ip link set eth0 down
Missing register, driver bug
WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60
Call trace:
xdp_rxq_info_unreg+0x58/0x60

__dev_change_flags+0xd8/0x210
dev_change_flags+0x24/0x64
do_setlink+0x230/0xdd0
...
This happens because virtnet_freeze() frees the receive_queue
completely (including struct xdp_rxq_info) but does not call
xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the
receive_queue again but does not call xdp_rxq_info_reg().
Actually, parts of virtnet_freeze_down() and virtnet_restore_up()
are almost identical to virtnet_close() and virtnet_open(): only
the calls to xdp_rxq_info_(un)reg() are missing. This means that
we can fix this easily and avoid such problems in the future by
just calling virtnet_close()/open() from the freeze/restore handlers.
Aside from adding the missing xdp_rxq_info calls the only difference
is that the refill work is only cancelled if netif_running(). However,
this should not make any functional difference since the refill work
should only be active if the network interface is actually up.

From: Jason A. Donenfeld <[email protected]>
commit f3eac426657d985b97c92fa5f7ae1d43f04721f3 upstream.
The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call.
Complicating things, however, is that POWER8 systems need some per-cpu
state and kmalloc, which isn't available at this stage. So we split
things up into an early phase and a later opportunistic phase. This
commit also removes some noisy log messages that don't add much.

commit 9ae6e8b1c9bbf6874163d1243e393137313762b7 upstream.
During postsuspend dm-era does the following:
1. Archives the current era
2. Commits the metadata, as part of the RPC call for archiving the
current era
3. Stops the worker
Until the worker stops, it might write to the metadata again. Moreover,
these writes are not flushed to disk immediately, but are cached by the
dm-bufio client, which writes them back asynchronously.
As a result, the committed metadata of a suspended dm-era device might
not be consistent with the in-core metadata.
In some cases, this can result in the corruption of the on-disk
metadata. Suppose the following sequence of events:
1. Load a new table, e.g. a snapshot-origin table, to a device with a
dm-era table
2. Suspend the device
3. dm-era commits its metadata, but the worker does a few more metadata
writes until it stops, as part of digesting an archived writeset
4. These writes are cached by the dm-bufio client
5. Load the dm-era table to another device.
6. The new instance of the dm-era target loads the committed, on-disk
metadata, which don't include the extra writes done by the worker
after the metadata commit.
7. Resume the new device
8. The new dm-era target instance starts using the metadata
9. Resume the original device
10. The destructor of the old dm-era target instance is called and
destroys the dm-bufio client, which results in flushing the cached
writes to disk
11. These writes might overwrite the writes done by the new dm-era
instance, hence corrupting its metadata.
Fix this by committing the metadata after the worker stops running.
stop_worker uses flush_workqueue to flush the current work. However, the
work item may re-queue itself and flush_workqueue doesn't wait for
re-queued works to finish.
This could result in the worker changing the metadata after they have
been committed, or writing to the metadata concurrently with the commit
in the postsuspend thread.
Use drain_workqueue instead, which waits until the work and all
re-queued works finish.

From: Chaitanya Kulkarni <[email protected]>
[ Upstream commit c03fd85de293a4f65fcb94a795bf4c12a432bb6c ]
nvme_clear_request() has a check for flag REQ_DONTPREP and it is called
from nvme_init_request() and nvme_setuo_cmd().
The function nvme_init_request() is called from nvme_alloc_request()
and nvme_alloc_request_qid(). From these two callers new request is
allocated everytime. For newly allocated request RQF_DONTPREP is never
set. Since after getting a tag, block layer sets the req->rq_flags == 0
and never sets the REQ_DONTPREP when returning the request :-
nvme_alloc_request()
blk_mq_alloc_request()
blk_mq_rq_ctx_init()
rq->rq_flags = 0 <----
nvme_alloc_request_qid()
blk_mq_alloc_request_hctx()
blk_mq_rq_ctx_init()
rq->rq_flags = 0 <----
The block layer does set req->rq_flags but REQ_DONTPREP is not one of
them and that is set by the driver.
That means we can unconditinally set the REQ_DONTPREP value to the
rq->rq_flags when nvme_init_request()->nvme_clear_request() is called
from above two callers.
Move the check for REQ_DONTPREP from nvme_clear_nvme_request() into
nvme_setup_cmd().
This is needed since nvme_alloc_request() now gets called from fast
path when NVMeOF target is configured with passthru backend to avoid
unnecessary checks in the fast path.

From: Kai-Heng Feng <[email protected]>
[ Upstream commit 4e0effd9007ea0be31f7488611eb3824b4541554 ]
Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps
Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which
will be significantly lower when 1) ASPM is disabled or 2) SoC package
c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx
speed can reach to ~950Mbps.
According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC",
"DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so
set it to 1b for "DMA is considered idle when there is no Rx or Tx AND
when there are no TLPs indicating that CPU is active detected on the
PCIe link (such as the host executes CSR or Configuration register read
or write operation)" and performing Tx should also fall under "active
CPU on PCIe link" case.
In addition to that, commit b6e0c419f040 ("igb: Move DMA Coalescing init
code to separate function.") seems to wrongly changed from enabling
E1000_PCIEMISC_LX_DECISION to disabling it, also fix that.

[ Upstream commit 345023b0db315648ccc3c1a36aee88304a8b4d91 ]
This new function combines the netlink register attribute parser
and the store validation function.
This update requires to replace:
enum nft_registers dreg:8;
in many of the expression private areas otherwise compiler complains
with:
error: cannot take address of bit-field ‘dreg’
when passing the register field as reference.

From: Xin Long <[email protected]>
[ Upstream commit be07f056396d6bb40963c45a02951c566ddeef8e ]
This patch is to use "struct work_struct" for the finalize work queue
instead of "struct tipc_net_work", as it can get the "net" and "addr"
from tipc_net's other members and there is no need to add extra net
and addr in tipc_net by defining "struct tipc_net_work".
Note that it's safe to get net from tn->bcl as bcl is always released
after the finalize work queue is done.

From: Samuel Holland <[email protected]>
[ Upstream commit 1342b5b23da9559a1578978eaff7f797d8a87d91 ]
If the component driver fails to bind, or is unbound, the driver data
for the top-level platform device points to a freed drm_device. If the
system is then suspended, the driver passes this dangling pointer to
drm_mode_config_helper_suspend(), which crashes.
Fix this by only setting the driver data while the platform driver holds
a reference to the drm_device.
Fixes: 624b4b48d9d8 ("drm: sun4i: Add support for suspending the display driver")

commit 33b29dbb39bcbd0a96e440646396bbf670b914fa upstream.
The EM05-G modem has 2 USB configurations that are configurable via the AT
command AT+QCFG="usbnet",[ 0 | 2 ] which make the modem enumerate with
the following interfaces, respectively:
"RMNET" : AT + DIAG + NMEA + Modem + QMI
"MBIM" : MBIM + AT + DIAG + NMEA + Modem
The detailed description of the USB configuration for each mode as follows:

commit 83810f84ecf11dfc5a9414a8b762c3501b328185 upstream.
If ports are not turned off in shutdown then runtime suspended
self-powered USB devices may survive in U3 link state over S5.
During subsequent boot, if firmware sends an IPC command to program
the port in DISCONNECT state, it will time out, causing significant
delay in the boot time.
Turning off roothub port power is also recommended in xhci
specification 4.19.4 "Port Power" in the additional note.

commit e5f3205b04d7f95a2ef43bce4b454a7f264d6923 upstream.
IIO trigger interface function iio_trigger_get() should be called after
iio_trigger_register() (or its devm analogue) strictly, because of
iio_trigger_get() acquires module refcnt based on the trigger->owner
pointer, which is initialized inside iio_trigger_register() to
THIS_MODULE.
If this call order is wrong, the next iio_trigger_put() (from sysfs
callback or "delete module" path) will dereference "default" module
refcnt, which is incorrect behaviour.

commit 12378a5a75e33f34f8586706eb61cca9e6d4690c upstream.
When a packet enters the OVS datapath and does not match any existing
flows installed in the kernel flow cache, the packet will be sent to
userspace to be parsed, and a new flow will be created. The kernel and
OVS rely on each other to parse packet fields in the same way so that
packets will be handled properly.
As per the design document linked below, OVS expects all later IPv6
fragments to have nw_proto=44 in the flow key, so they can be correctly
matched on OpenFlow rules. OpenFlow controllers create pipelines based
on this design.
This behavior was changed by the commit in the Fixes tag so that
nw_proto equals the next_header field of the last extension header.
However, there is no counterpart for this change in OVS userspace,
meaning that this field is parsed differently between OVS and the
kernel. This is a problem because OVS creates actions based on what is
parsed in userspace, but the kernel-provided flow key is used as a match
criteria, as described in Documentation/networking/openvswitch.rst. This
leads to issues such as packets incorrectly matching on a flow and thus
the wrong list of actions being applied to the packet. Such changes in
packet parsing cannot be implemented without breaking the userspace.
The offending commit is partially reverted to restore the expected
behavior.
The change technically made sense and there is a good reason that it was
implemented, but it does not comply with the original design of OVS.
If in the future someone wants to implement such a change, then it must
be user-configurable and disabled by default to preserve backwards
compatibility with existing OVS versions.

[ Upstream commit 566d3c57eb526f32951af15866086e236ce1fc8a ]
When a write command to a sequential write required or sequential write
preferred zone result in the zone write pointer reaching the end of the
zone, the zone condition must be set to full AND the number of implicitly
or explicitly open zones updated to have a correct accounting for zone
resources. However, the function zbc_inc_wp() only sets the zone condition
to full without updating the open zone counters, resulting in a zone state
machine breakage.
Introduce the helper function zbc_set_zone_full() and use it in
zbc_inc_wp() to correctly transition zones to the full condition.

commit 93a8ba2a619816d631bd69e9ce2172b4d7a481b8 upstream.
Contrary to what was believed at the time, the ramp delay of 150us is not
plenty for the PU LDO with the default step time of 512 pulses of the 24MHz
clock. Measurements have shown that after enabling the LDO the voltage on
VDDPU_CAP jumps to ~750mV in the first step and after that the regulator
executes the normal ramp up as defined by the step size control.
This means it takes the regulator between 360us and 370us to ramp up to
the nominal 1.15V voltage for this power domain. With the old setting of
the ramp delay the power up of the PU GPC domain would happen in the middle
of the regulator ramp with the voltage being at around 900mV. Apparently
this was enough for most units to properly power up the peripherals in the
domain and execute the reset. Some units however, fail to power up properly,
especially when the chip is at a low temperature. In that case any access
to the GPU registers would yield an incorrect result with no way to recover
from this situation.
Change the ramp delay to 380us to cover the measured ramp up time with a
bit of additional slack.

commit 56ec3e755bd1041d35bdec020a99b327697ee470 upstream.
It turned out that Lenovo shipped two completely different products
with the very same PCI SSID, where both require different quirks;
namely, Lenovo C940 has already the fixup for its speaker
(ALC298_FIXUP_LENOVO_SPK_VOLUME) with the PCI SSID 17aa:3818, while
Yoga Duet 7 has also the very same PCI SSID but requires a different
quirk, ALC287_FIXUP_YOGA7_14TIL_SPEAKERS.
Fortunately, both are with different codecs (C940 with ALC298 and Duet
7 with ALC287), hence we can apply different fixes by checking the
codec ID. This patch implements that special fixup function.
For easier handling, the internal function for applying a specific
fixup entry is exported as __snd_hda_apply_fixup(), so that it can be
called from the codec driver. The rest is simply calling it with a
different fixup ID depending on the codec ID.

commit 28438794aba47a27e922857d27b31b74e8559143 upstream.
Since commit f02e8a6596b7 ("module: Sort exported symbols"),
EXPORT_SYMBOL* is placed in the individual section ___ksymtab(_gpl)+<sym>
(3 leading underscores instead of 2).
Since then, modpost cannot detect the bad combination of EXPORT_SYMBOL
and __init/__exit.
Fix the .fromsec field.

Even when the eth port is resticted to work with speeds not higher than 1G,
and so the eth driver is requesting the phy (via phylink) to advertise up
to 1000BASET support, the aquantia phy device is still advertising for 2.5G
and 5G speeds.
Clear these advertising defaults when requested.

[ Upstream commit 3046a827316c0e55fc563b4fb78c93b9ca5c7c37 ]
A customer reported a request_socket leak in a Calico cloud environment. We
found that a BPF program was doing a socket lookup with takes a refcnt on
the socket and that it was finding the request_socket but returning the parent
LISTEN socket via sk_to_full_sk() without decrementing the child request socket
1st, resulting in request_sock slab object leak. This patch retains the
existing behaviour of returning full socks to the caller but it also decrements
the child request_socket if one is present before doing so to prevent the leak.
Thanks to Curtis Taylor for all the help in diagnosing and testing this. And
thanks to Antoine Tenart for the reproducer and patch input.
v2 of this patch contains, refactor as per Daniel Borkmann's suggestions to
validate RCU flags on the listen socket so that it balances with bpf_sk_release()
and update comments as per Martin KaFai Lau's suggestion. One small change to
Daniels suggestion, put "sk = sk2" under "if (sk2 != sk)" to avoid an extra
instruction.
Fixes: f7355a6c0497 ("bpf: Check sk_fullsock() before returning from bpf_sk_lookup()")

commit c01d4d0a82b71857be7449380338bc53dde2da92 upstream.
random.c ratelimits how much it warns about uninitialized urandom reads
using __ratelimit(). When the RNG is finally initialized, it prints the
number of missed messages due to ratelimiting.
It has been this way since that functionality was introduced back in
2018. Recently, cc1e127bfa95 ("random: remove ratelimiting for in-kernel
unseeded randomness") put a bit more stress on the urandom ratelimiting,
which teased out a bug in the implementation.
Specifically, when under pressure, __ratelimit() will print its own
message and reset the count back to 0, making the final message at the
end less useful. Secondly, it does so as a pr_warn(), which apparently
is undesirable for people's CI.
Fortunately, __ratelimit() has the RATELIMIT_MSG_ON_RELEASE flag exactly
for this purpose, so we set the flag.
Fixes: 4e00b339e264 ("random: rate limit unseeded randomness warnings")

From: Alan Stern <[email protected]>
commit f2d8c2606825317b77db1f9ba0fc26ef26160b30 upstream.
In a report for a separate bug (which has already been fixed by commit
5f0b5f4d50fa "usb: gadget: fix race when gadget driver register via
ioctl") in the raw-gadget driver, the syzbot console log included
error messages caused by attempted registration of a new driver with
the same name as an existing driver:
> kobject_add_internal failed for raw-gadget with -EEXIST, don't try to register things with the same name in the same directory.
> UDC core: USB Raw Gadget: driver registration failed: -17
> misc raw-gadget: fail, usb_gadget_register_driver returned -17
These errors arise because raw_gadget.c registers a separate UDC
driver for each of the UDC instances it creates, but these drivers all
have the same name: "raw-gadget". Until recently this wasn't a
problem, but when the "gadget" bus was added and UDC drivers were
registered on this bus, it became possible for name conflicts to cause
the registrations to fail. The reason is simply that the bus code in
the driver core uses the driver name as a sysfs directory name (e.g.,
/sys/bus/gadget/drivers/raw-gadget/), and you can't create two
directories with the same pathname.
To fix this problem, the driver names used by raw-gadget are made
distinct by appending a unique ID number: "raw-gadget.N", with a
different value of N for each driver instance. And to avoid the
proliferation of error handling code in the raw_ioctl_init() routine,
the error return paths are refactored into the common pattern (goto
statements leading to cleanup code at the end of the routine).

[ Upstream commit c81aba8fde2aee4f5778ebab3a1d51bd2ef48e4c ]
commit 979934da9e7a ("[PATCH] mips: update IRQ handling for vr41xx") added
a function irq_dispatch, and it'll increase irq_err_count when the get_irq
callback returns a negative value, but increase irq_err_count in get_irq
was not removed.
And also, modpost complains once gpio-vr41xx drivers become modules.
ERROR: modpost: "irq_err_count" [drivers/gpio/gpio-vr41xx.ko] undefined!
So it would be a good idea to remove repetitive increase irq_err_count in
get_irq callback.

commit ec6d0dde71d760aa60316f8d1c9a1b0d99213529 upstream.
On execve[at], we are zero'ing out most of the thread register state
including gpr[0], which contains the syscall number. Due to this, we
fail to trigger the syscall exit tracepoint properly. Fix this by
retaining gpr[0] in the thread register state.

commit d2214cca4d3eadc74eac9e30301ec7cad5355f00 upstream.
The irq handler was only checking the mask for the first ADCs in the case of the
F4 and H7 generation, since it was iterating up to the num_irq value. This patch add
the maximum number of ADC in the common register, which map to the number of entries of
eoc_msk and ovr_msk in stm32_adc_common_regs. This allow the handler to check all ADCs in
that module.
Tested on a STM32F429NIH6.

[ Upstream commit 69135c572d1f84261a6de2a1268513a7e71753e2 ]
After setting the sock ktls, update ctx->sk_proto to sock->sk_prot by
tls_update(), so now ctx->sk_proto->close is tls_sk_proto_close(). When
close the sock, tls_sk_proto_close() is called for sock->sk_prot->close
is tls_sk_proto_close(). But ctx->sk_proto->close() will be executed later
in tls_sk_proto_close(). Thus tls_sk_proto_close() executed repeatedly
occurred. That will trigger the following bug.

Updating a proto which is same with sock->sk_prot is incorrect. Add proto

From: Mikulas Patocka <[email protected]>
commit 90736eb3232d208ee048493f371075e4272e0944 upstream.
Commit 85e123c27d5c ("dm mirror log: round up region bitmap size to
BITS_PER_LONG") introduced a regression on 64-bit architectures in the
lvm testsuite tests: lvcreate-mirror, mirror-names and vgsplit-operation.
If the device is shrunk, we need to clear log bits beyond the end of the
device. The code clears bits up to a 32-bit boundary and then calculates
lc->sync_count by summing set bits up to a 64-bit boundary (the commit
changed that; previously, this boundary was 32-bit too). So, it was using
some non-zeroed bits in the calculation and this caused misbehavior.
Fix this regression by clearing bits up to BITS_PER_LONG boundary.

commit 06781a5026350cde699d2d10c9914a25c1524f45 upstream.
The DEVICE_BUSY_TIMEOUT value is described in the Reference Manual as:
| Timeout waiting for NAND Ready/Busy or ATA IRQ. Used in WAIT_FOR_READY
| mode. This value is the number of GPMI_CLK cycles multiplied by 4096.
So instead of multiplying the value in cycles with 4096, we have to
divide it by that value. Use DIV_ROUND_UP to make sure we are on the
safe side, especially when the calculated value in cycles is smaller
than 4096 as typically the case.
This bug likely never triggered because any timeout != 0 usually will
do. In my case the busy timeout in cycles was originally calculated as
2408, which multiplied with 4096 is 0x968000. The lower 16 bits were
taken for the 16 bit wide register field, so the register value was
0x8000. With 2970bf5a32f0 ("mtd: rawnand: gpmi: fix controller timings
setting") however the value in cycles became 2384, which multiplied
with 4096 is 0x950000. The lower 16 bit are 0x0 now resulting in an
intermediate timeout when reading from NAND.

[ Upstream commit be857b7f77d130dbbd47c91fc35198b040f35865 ]
Events CPU_CYCLES and INSTRUCTIONS can be submitted with two different
perf_event attribute::type values:
- PERF_TYPE_HARDWARE: when invoked via perf tool predefined events name
cycles or cpu-cycles or instructions.
- pmu->type: when invoked via perf tool event name cpu_cf/CPU_CYLCES/ or
cpu_cf/INSTRUCTIONS/. This invocation also selects the PMU to which
the event belongs.
Handle both type of invocations identical for events CPU_CYLCES and
INSTRUCTIONS. They address the same hardware.
The result is different when event modifier exclude_kernel is also set.
Invocation with event modifier for user space event counting fails.
Output before:

commit 37d838de369b07b596c19ff3662bf0293fdb09ee upstream.
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
In brcmstb_init_sram, it pass dn to of_address_to_resource(),
of_address_to_resource() will call of_find_device_by_node() to take
reference, so we should release the reference returned by
of_find_matching_node().

commit 99bded02dae5e1e2312813506c41dc8db2fb656c upstream.
The check for spurious IRQs introduced in 695e2f5c289bb assumed that the bits
in the control and status registers are aligned. This is true for the H7 and MP1
version, but not the F4. The interrupt was then never handled on the F4.
Instead of increasing the complexity of the comparison and check each bit specifically,
we remove this check completely and rely on the generic handler for spurious IRQs.

Right now nvme_alloc_request() allocates a request from block layer
based on the value of the qid. When qid set to NVME_QID_ANY it used
blk_mq_alloc_request() else blk_mq_alloc_request_hctx().
The function nvme_alloc_request() is called from different context, The
only place where it uses non NVME_QID_ANY value is for fabrics connect
commands :-
nvme_submit_sync_cmd() NVME_QID_ANY
nvme_features() NVME_QID_ANY
nvme_sec_submit() NVME_QID_ANY
nvmf_reg_read32() NVME_QID_ANY
nvmf_reg_read64() NVME_QID_ANY
nvmf_reg_write32() NVME_QID_ANY
nvmf_connect_admin_queue() NVME_QID_ANY
nvme_submit_user_cmd() NVME_QID_ANY

nvme_keep_alive() NVME_QID_ANY
nvme_alloc_request()
nvme_timeout() NVME_QID_ANY
nvme_alloc_request()
nvme_delete_queue() NVME_QID_ANY
nvme_alloc_request()
nvmet_passthru_execute_cmd() NVME_QID_ANY
nvme_alloc_request()
nvmf_connect_io_queue() QID
__nvme_submit_sync_cmd()
nvme_alloc_request()
With passthru nvme_alloc_request() now falls into the I/O fast path such
that blk_mq_alloc_request_hctx() is never gets called and that adds
additional branch check in fast path.
Split the nvme_alloc_request() into nvme_alloc_request() and
nvme_alloc_request_qid().
Replace each call of the nvme_alloc_request() with NVME_QID_ANY param
with a call to newly added nvme_alloc_request() without NVME_QID_ANY.
Replace a call to nvme_alloc_request() with QID param with a call to
newly added nvme_alloc_request() and nvme_alloc_request_qid()
based on the qid value set in the __nvme_submit_sync_cmd().

[ Upstream commit ce0db505bc0c51ef5e9ba446c660de7e26f78f29 ]
Following commit 17e822f7591f ("drm/msm: fix unbalanced
pm_runtime_enable in adreno_gpu_{init, cleanup}"), any call to
adreno_unbind() will disable runtime PM twice, as indicated by the call
trees below:
adreno_unbind()
-> pm_runtime_force_suspend()
-> pm_runtime_disable()
adreno_unbind()
-> gpu->funcs->destroy() [= aNxx_destroy()]
-> adreno_gpu_cleanup()
-> pm_runtime_disable()
Note that pm_runtime_force_suspend() is called right before
gpu->funcs->destroy() and both functions are called unconditionally.
With recent addition of the eDP AUX bus code, this problem manifests
itself when the eDP panel cannot be found yet and probing is deferred.
On the first probe attempt, we disable runtime PM twice as described
above. This then causes any later probe attempt to fail with
[drm:adreno_load_gpu [msm]] *ERROR* Couldn't power up the GPU: -13
preventing the driver from loading.
As there seem to be scenarios where the aNxx_destroy() functions are not
called from adreno_unbind(), simply removing pm_runtime_disable() from
inside adreno_unbind() does not seem to be the proper fix. This is what
commit 17e822f7591f ("drm/msm: fix unbalanced pm_runtime_enable in
adreno_gpu_{init, cleanup}") intended to fix. Therefore, instead check
whether runtime PM is still enabled, and only disable it in that case.

[ Upstream commit ff672c67ee7635ca1e28fb13729e8ef0d1f08ce5 ]
On x86-64 the tail call count is passed from one BPF function to another
through %rax. Additionally, on function entry, the tail call count value
is stored on stack right after the BPF program stack, due to register
shortage.
The stored count is later loaded from stack either when performing a tail
call - to check if we have not reached the tail call limit - or before
calling another BPF function call in order to pass it via %rax.
In the latter case, we miscalculate the offset at which the tail call count
was stored on function entry. The JIT does not take into account that the
allocated BPF program stack is always a multiple of 8 on x86, while the
actual stack depth does not have to be.
This leads to a load from an offset that belongs to the BPF stack, as shown
in the example below:
SEC("tc")
int entry(struct __sk_buff *skb)
{
/* Have data on stack which size is not a multiple of 8 */
volatile char arr[1] = {};
return subprog_tail(skb);
}
int entry(struct __sk_buff * skb):
0: (b4) w2 = 0
1: (73) *(u8 *)(r10 -1) = r2
2: (85) call pc+1#bpf_prog_ce2f79bb5f3e06dd_F
3: (95) exit
int entry(struct __sk_buff * skb):
0xffffffffa0201788: nop DWORD PTR [rax+rax*1+0x0]
0xffffffffa020178d: xor eax,eax
0xffffffffa020178f: push rbp

0xffffffffa02017ad: leave

Fix it by rounding up the BPF stack depth to a multiple of 8, when
calculating the tail call count offset on stack.

Since commit 9bcf15f75cac ("iio: adc: axp288: Fix TS-pin handling") we
preserve the bias current set by the firmware at boot. This fixes issues
we were seeing on various models.
Some models like the Nuvision Solo 10 Draw tablet actually need the
old hardcoded 80ųA bias current for battery temperature monitoring
to work properly.
Add a quirk entry for the Nuvision Solo 10 Draw to the DMI quirk table
to restore setting the bias current to 80ųA on this model.

commit 53632ba87d9f302a8d97a11ec2f4f4eec7bb75ea upstream.
If CONFIG_TRIM_UNUSED_KSYMS is enabled and the kernel is built from
a pristine state, the vmlinux is linked twice.
Commit 3fdc7d3fe4c0 ("kbuild: link vmlinux only once for
CONFIG_TRIM_UNUSED_KSYMS") explains why this happens, but it did not fix
the issue at all.
Now I realized I had applied a wrong patch.
In v1 patch [1], the autoksyms_recursive target correctly recurses to
"$(MAKE) -f $(srctree)/Makefile autoksyms_recursive".
In v2 patch [2], I accidentally dropped the diff line, and it recurses to
"$(MAKE) -f $(srctree)/Makefile vmlinux".
Restore the code I intended in v1.

commit e561e472a3d441753bd012333b057f48fef1045b upstream.
The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call. Fortunately,
each platform already has a setup_arch function pointer, which means
it's easy to wire this up. This commit also removes some noisy log
messages that don't add much.

[ Upstream commit cb78d1b5efffe4cf97e16766329dd7358aed3deb ]
The recent patch to make afs_getattr consult the server didn't account
for the pseudo-inodes employed by the dynamic root-type afs superblock
not having a volume or a server to access, and thus an oops occurs if
such a directory is stat'd.
Fix this by checking to see if the vnode->volume pointer actually points
anywhere before following it in afs_getattr().
This can be tested by stat'ing a directory in /afs. It may be
sufficient just to do "ls /afs" and the oops looks something like:

2.35.1
From: Takashi Iwai <[email protected]>
commit 5faa0bc69102f3a4c605581564c367be5eb94dfa upstream.
Currently the Conexant codec driver sets up the beep NID after calling
snd_hda_gen_parse_auto_config(). It turned out that this results in
the insufficient setup for the beep control, as the generic parser
handles the fake path in snd_hda_gen_parse_auto_config() only if the
beep_nid is set up beforehand.
For dealing with the beep widget properly, call cx_auto_parse_beep()
before snd_hda_gen_parse_auto_config() call.
Fixes: 51e19ca5f755 ("ALSA: hda/conexant - Clean up beep code")

From: Dmitry Rokosov <[email protected]>
commit 9354c224c9b4f55847a0de3e968cba2ebf15af3b upstream.
IIO trigger interface function iio_trigger_get() should be called after
iio_trigger_register() (or its devm analogue) strictly, because of
iio_trigger_get() acquires module refcnt based on the trigger->owner
pointer, which is initialized inside iio_trigger_register() to
THIS_MODULE.
If this call order is wrong, the next iio_trigger_put() (from sysfs
callback or "delete module" path) will dereference "default" module
refcnt, which is incorrect behaviour.

There is however a section warning generated which is already reported
in the 5.4 stable queue discussion:
