6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zev Weiss <zev@bewilderbeest.net>
commit 920057ad521dc8669e534736c2a12c14ec9fb2d7 upstream.
In the regmap conversion in commit 4ef2774511dc ("hwmon: (nct6775)
Convert register access to regmap API") I reused the 'reg' variable
for all three register reads in the fan speed calculation loop in
nct6775_update_device(), but failed to notice that the value from the
first one (data->REG_FAN[i]) is actually used in the call to
nct6775_select_fan_div() at the end of the loop body. Since that
patch the register value passed to nct6775_select_fan_div() has been
(conditionally) incorrectly clobbered with the value of a different
register than intended, which has in at least some cases resulted in
fan speeds being adjusted down to zero.
Fix this by using dedicated temporaries for the two intermediate
register reads instead of 'reg'.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chengming Zhou <zhouchengming@bytedance.com>
[ Upstream commit c0490bc9bb62d9376f3dd4ec28e03ca0fef97152 ]
We don't need to maintain per-queue leaf_cfs_rq_list on !SMP, since
it's used for cfs_rq load tracking & balancing on SMP.
But sched debug interface uses it to print per-cfs_rq stats.
This patch fixes the !SMP version of cfs_rq_is_decayed(), so the
per-queue leaf_cfs_rq_list is also maintained correctly on !SMP,
to fix the warning in assert_list_leaf_cfs_rq().
Fixes: 0a00a354644e ("sched/fair: Delete useless condition in tg_unthrottle_up()")

From: David Howells <dhowells@redhat.com>
[ Upstream commit 066baf92bed934c9fb4bcee97a193f47aa63431c ]
copy_mc_to_user() has the destination marked __user on powerpc, but not on
x86; the latter results in a sparse warning in lib/iov_iter.c.
Fix this by applying the tag on x86 too.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Qais Yousef <qyousef@layalina.io>
[ Upstream commit 6b00a40147653c8ea748e8f4396510f252763364 ]
When uclamp_max is being used, the util of the task could be higher than
the spare capacity of the CPU, but due to uclamp_max value we force-fit
it there.
The way the condition for checking for max_spare_cap in
find_energy_efficient_cpu() was constructed; it ignored any CPU that has
its spare_cap less than or _equal_ to max_spare_cap. Since we initialize
max_spare_cap to 0; this lead to never setting max_spare_cap_cpu and
hence ending up never performing compute_energy() for this cluster and
missing an opportunity for a better energy efficient placement to honour
uclamp_max setting.
max_spare_cap = 0;
cpu_cap = capacity_of(cpu) - cpu_util(p); // 0 if cpu_util(p) is high
...
util_fits_cpu(...); // will return true if uclamp_max forces it to fit
...
// this logic will fail to update max_spare_cap_cpu if cpu_cap is 0
if (cpu_cap > max_spare_cap) {
max_spare_cap = cpu_cap;
max_spare_cap_cpu = cpu;
}
prev_spare_cap suffers from a similar problem.
Fix the logic by converting the variables into long and treating -1
value as 'not populated' instead of 0 which is a viable and correct
spare capacity value. We need to be careful signed comparison is used
when comparing with cpu_cap in one of the conditions.

From: Qais Yousef <qyousef@layalina.io>
[ Upstream commit 23c9519def98ee0fa97ea5871535e9b136f522fc ]
find_energy_efficient_cpu() bails out early if effective util of the
task is 0 as the delta at this point will be zero and there's nothing
for EAS to do. When uclamp is being used, this could lead to wrong
decisions when uclamp_max is set to 0. In this case the task is capped
to performance point 0, but it is actually running and consuming energy
and we can benefit from EAS energy calculations.
Rework the condition so that it bails out when both util and uclamp_min
are 0.
We can do that without needing to use uclamp_task_util(); remove it.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Zijlstra <peterz@infradead.org>
[ Upstream commit f0498d2a54e7966ce23cd7c7ff42c64fa0059b07 ]
Kuyo reported sporadic failures on a sched_setaffinity() vs CPU
hotplug stress-test -- notably affine_move_task() remains stuck in
wait_for_completion(), leading to a hung-task detector warning.
Specifically, it was reported that stop_one_cpu_nowait(.fn =
migration_cpu_stop) returns false -- this stopper is responsible for
the matching complete().
The race scenario is:
CPU0 CPU1
// doing _cpu_down()
__set_cpus_allowed_ptr()
task_rq_lock();
takedown_cpu()
stop_machine_cpuslocked(take_cpu_down..)
<PREEMPT: cpu_stopper_thread()
MULTI_STOP_PREPARE
...
__set_cpus_allowed_ptr_locked()
affine_move_task()
task_rq_unlock();
<PREEMPT: cpu_stopper_thread()\>
ack_state()
MULTI_STOP_RUN
take_cpu_down()
__cpu_disable();
stop_machine_park();
stopper->enabled = false;
/>
/>
stop_one_cpu_nowait(.fn = migration_cpu_stop);
if (stopper->enabled) // false!!!
That is, by doing stop_one_cpu_nowait() after dropping rq-lock, the
stopper thread gets a chance to preempt and allows the cpu-down for
the target CPU to complete.
OTOH, since stop_one_cpu_nowait() / cpu_stop_queue_work() needs to
issue a wakeup, it must not be ran under the scheduler locks.
Solve this apparent contradiction by keeping preemption disabled over
the unlock + queue_stopper combination:
preempt_disable();
task_rq_unlock(...);
if (!stop_pending)
stop_one_cpu_nowait(...)
preempt_enable();
This respects the lock ordering contraints while still avoiding the
above race. That is, if we find the CPU is online under rq-lock, the
targeted stop_one_cpu_nowait() must succeed.
Apply this pattern to all similar stop_one_cpu_nowait() invocations.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Reuben Hawkins <reubenhwk@gmail.com>
[ Upstream commit 7116c0af4b8414b2f19fdb366eea213cbd9d91c2 ]
Readahead was factored to call generic_fadvise. That refactor added an
S_ISREG restriction which broke readahead on block devices.
In addition to S_ISREG, this change checks S_ISBLK to fix block device
readahead. There is no change in behavior with any file type besides block
devices in this change.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jingbo Xu <jefflexu@linux.alibaba.com>
[ Upstream commit 6654408a33e6297d8e1d2773409431d487399b95 ]
The cgwb cleanup routine will try to release the dying cgwb by switching
the attached inodes. It fetches the attached inodes from wb->b_attached
list, omitting the fact that inodes only with dirty timestamps reside in
wb->b_dirty_time list, which is the case when lazytime is enabled. This
causes enormous zombie memory cgroup when lazytime is enabled, as inodes
with dirty timestamps can not be switched to a live cgwb for a long time.
It is reasonable not to switch cgwb for inodes with dirty data, as
otherwise it may break the bandwidth restrictions. However since the
writeback of inode metadata is not accounted for, let's also switch
inodes with dirty timestamps to avoid zombie memory and block cgroups
when laztytime is enabled.

From: Ben Wolsieffer <ben.wolsieffer@hefring.com>
[ Upstream commit c73801ae4f22b390228ebf471d55668e824198b6 ]
On no-MMU, all futexes are treated as private because there is no need
to map a virtual address to physical to match the futex across
processes. This doesn't quite work though, because private futexes
include the current process's mm_struct as part of their key. This makes
it impossible for one process to wake up a shared futex being waited on
in another process.
Fix this bug by excluding the mm_struct from the key. With
a single address space, the futex address is already a unique key.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alison Schofield <alison.schofield@intel.com>
[ Upstream commit 8f012db27c9516be1a7aca93ea4a6ca9c75056c9 ]
numa_fill_memblks() fills in the gaps in numa_meminfo memblks
over an physical address range.
The ACPI driver will use numa_fill_memblks() to implement a new Linux
policy that prescribes extending proximity domains in a portion of a
CFMWS window to the entire window.
Dan Williams offered this explanation of the policy:
A CFWMS is an ACPI data structure that indicates *potential* locations
where CXL memory can be placed. It is the playground where the CXL
driver has free reign to establish regions. That space can be populated
by BIOS created regions, or driver created regions, after hotplug or
other reconfiguration.
When BIOS creates a region in a CXL Window it additionally describes
that subset of the Window range in the other typical ACPI tables SRAT,
SLIT, and HMAT. The rationale for BIOS not pre-describing the entire
CXL Window in SRAT, SLIT, and HMAT is that it can not predict the
future. I.e. there is nothing stopping higher or lower performance
devices being placed in the same Window. Compare that to ACPI memory
hotplug that just onlines additional capacity in the proximity domain
with little freedom for dynamic performance differentiation.
That leaves the OS with a choice, should unpopulated window capacity
match the proximity domain of an existing region, or should it allocate
a new one? This patch takes the simple position of minimizing proximity
domain proliferation by reusing any proximity domain intersection for
the entire Window. If the Window has no intersections then allocate a
new proximity domain. Note that SRAT, SLIT and HMAT information can be
enumerated dynamically in a standard way from device provided data.
Think of CXL as the end of ACPI needing to describe memory attributes,
CXL offers a standard discovery model for performance attributes, but
Linux still needs to interoperate with the old regime.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alison Schofield <alison.schofield@intel.com>
[ Upstream commit 8f1004679987302b155f14b966ca6d4335814fcb ]
Commit fd49f99c1809 ("ACPI: NUMA: Add a node and memblk for each
CFMWS not in SRAT") did not account for the case where the BIOS
only partially describes a CFMWS Window in the SRAT. That means
the omitted address ranges, of a partially described CFMWS Window,
do not get assigned to a NUMA node.
Replace the call to phys_to_target_node() with numa_add_memblks().
Numa_add_memblks() searches an HPA range for existing memblk(s)
and extends those memblk(s) to fill the entire CFMWS Window.
Extending the existing memblks is a simple strategy that reuses
SRAT defined proximity domains from part of a window to fill out
the entire window, based on the knowledge* that all of a CFMWS
window is of a similar performance class.
*Note that this heuristic will evolve when CFMWS Windows present
a wider range of characteristics. The extension of the proximity
domain, implemented here, is likely a step in developing a more
sophisticated performance profile in the future.
There is no change in behavior when the SRAT does not describe
the CFMWS Window at all. In that case, a new NUMA node with a
single memblk covering the entire CFMWS Window is created.
Fixes: fd49f99c1809 ("ACPI: NUMA: Add a node and memblk for each CFMWS not in SRAT")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adam Dunlap <acdunlap@google.com>
[ Upstream commit f79936545fb122856bd78b189d3c7ee59928c751 ]
Previously, if copy_from_kernel_nofault() was called before
boot_cpu_data.x86_virt_bits was set up, then it would trigger undefined
behavior due to a shift by 64.
This ended up causing boot failures in the latest version of ubuntu2204
in the gcp project when using SEV-SNP.
Specifically, this function is called during an early #VC handler which
is triggered by a CPUID to check if NX is implemented.
Fixes: 1aa9aa8ee517 ("x86/sev-es: Setup GHCB-based boot #VC handler")

From: Yuntao Wang <ytcoode@gmail.com>
[ Upstream commit 001470fed5959d01faecbd57fcf2f60294da0de1 ]
Since the size value is added to the base address to yield the last valid
byte address of the GDT, the current size value of startup_gdt_descr is
incorrect (too large by one), fix it.
[ mingo: This probably never mattered, because startup_gdt[] is only used
in a very controlled fashion - but make it consistent nevertheless. ]

[ Upstream commit 12590d4d0e331d3cb9e6b3494515cd61c8a6624e ]
clk_get_rate() might sleep, and that prevents dm-timer based PWM from being
used from atomic context.
Fix that by getting fclk rate in probe() and using a notifier in case rate
changes.

Use the smaller of the two buffer sizes when calling strnlen(). When
src length is unknown (SIZE_MAX), it is adjusted to use dest length,
which is what the original code did.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen Yu <yu.c.chen@intel.com>
[ Upstream commit a0b0bad10587ae2948a7c36ca4ffc206007fbcf3 ]
When a CPU is about to be offlined, x86 validates that all active
interrupts which are targeted to this CPU can be migrated to the remaining
online CPUs. If not, the offline operation is aborted.
The validation uses irq_matrix_allocated() to retrieve the number of
vectors which are allocated on the outgoing CPU. The returned number of
allocated vectors includes also vectors which are associated to managed
interrupts.
That's overaccounting because managed interrupts are:
- not migrated when the affinity mask of the interrupt targets only
the outgoing CPU
- migrated to another CPU, but in that case the vector is already
pre-allocated on the potential target CPUs and must not be taken into
account.
As a consequence the check whether the remaining online CPUs have enough
capacity for migrating the allocated vectors from the outgoing CPU might
fail incorrectly.
Let irq_matrix_allocated() return only the number of allocated non-managed
interrupts to make this validation check correct.

From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit 56cfb8ce1f7f6c4e5ca571a2ec0880e131cd0311 ]
There may be sometimes reasons to actually run the work
if it's pending, add flush functions for both regular and
delayed wiphy work that will do this.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit eadfb54756aea5610d8d0a467f66305f777c85dd ]
This also has the wiphy locked here then. We need to use
the _locked version of cfg80211_sched_scan_stopped() now,
which also fixes an old deadlock there.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
[ Upstream commit e0c1ca236e28e4263fba76d47a108ed95dcae33e ]
In case the user sets the enable_ini to some preset, we want to honor
the value.
Remove the ops to set the value of the module parameter is runtime, we
don't want to allow to modify the value in runtime since we configure
the firmware once at the beginning on its life.
Fixes: b49c2b252b58 ("iwlwifi: Configure FW debug preset via module param.")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brett Creeley <brett.creeley@intel.com>
[ Upstream commit 221465de6bd8090ab61267f019866e8d2dd4ea3d ]
Currently when configuring promiscuous mode on the AVF we detect a
change in the netdev->flags. We use IFF_PROMISC and IFF_ALLMULTI to
determine whether or not we need to request/release promiscuous mode
and/or multicast promiscuous mode. The problem is that the AQ calls for
setting/clearing promiscuous/multicast mode are treated separately. This
leads to a case where we can trigger two promiscuous mode AQ calls in
a row with the incorrect state. To fix this make a few changes.
Use IAVF_FLAG_AQ_CONFIGURE_PROMISC_MODE instead of the previous
IAVF_FLAG_AQ_[REQUEST|RELEASE]_[PROMISC|ALLMULTI] flags.
In iavf_set_rx_mode() detect if there is a change in the
netdev->flags in comparison with adapter->flags and set the
IAVF_FLAG_AQ_CONFIGURE_PROMISC_MODE aq_required bit. Then in
iavf_process_aq_command() only check for IAVF_FLAG_CONFIGURE_PROMISC_MODE
and call iavf_set_promiscuous() if it's set.
In iavf_set_promiscuous() check again to see which (if any) promiscuous
mode bits have changed when comparing the netdev->flags with the
adapter->flags. Use this to set the flags which get sent to the PF
driver.
Add a spinlock that is used for updating current_netdev_promisc_flags
and only allows one promiscuous mode AQ at a time.
[1] Fixes the fact that we will only have one AQ call in the aq_required
queue at any one time.
[2] Streamlines the change in promiscuous mode to only set one AQ
required bit.
[3] This allows us to keep track of the current state of the flags and
also makes it so we can take the most recent netdev->flags promiscuous
mode state.
[4] This fixes the problem where a change in the netdev->flags can cause
IAVF_FLAG_AQ_CONFIGURE_PROMISC_MODE to be set in iavf_set_rx_mode(),
but cleared in iavf_set_promiscuous() before the change is ever made via
AQ call.

From: Leon Hwang <hffilwlqm@gmail.com>
[ Upstream commit 96daa9874211d5497aa70fa409b67afc29f0cb86 ]
Get and check data_fd. It should not check map_fd again.
Meanwhile, correct some 'return' to 'goto out'.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miri Korenblit <miriam.rachel.korenblit@intel.com>
[ Upstream commit 499d02790495958506a64f37ceda7e97345a50a8 ]
Currently we are setting the rate in the tx cmd for
mgmt frames (e.g. during connection establishment).
This was problematic when sending mgmt frames in eSR mode,
as we don't know what link this frame will be sent on
(This is decided by the FW), so we don't know what is the
lowest rate.
Fix this by not setting the rate in tx cmd and rely
on FW to choose the right one.
Set rate only for injected frames with fixed rate,
or when no sta is given.
Also set for important frames (EAPOL etc.) the High Priority flag.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aananth V <aananthv@google.com>
[ Upstream commit e326578a21414738de45f77badd332fb00bd0f58 ]
For passive TCP Fast Open sockets that had SYN/ACK timeout and did not
send more data in SYN_RECV, upon receiving the final ACK in 3WHS, the
congestion state may awkwardly stay in CA_Loss mode unless the CA state
was undone due to TCP timestamp checks. However, if
tcp_rcv_synrecv_state_fastopen() decides not to undo, then we should
enter CA_Open, because at that point we have received an ACK covering
the retransmitted SYNACKs. Currently, the icsk_ca_state is only set to
CA_Open after we receive an ACK for a data-packet. This is because
tcp_ack does not call tcp_fastretrans_alert (and tcp_process_loss) if
!prior_packets
Note that tcp_process_loss() calls tcp_try_undo_recovery(), so having
tcp_rcv_synrecv_state_fastopen() decide that if we're in CA_Loss we
should call tcp_try_undo_recovery() is consistent with that, and
low risk.

protection that struct_size() adds against potential integer overflows
is defeated. Fix this by hardening call to struct_size() with size_add().

[ Upstream commit e22c6ea025013ae447fe269269753ffec763dde5 ]
If, for any reason, the open-coded arithmetic causes a wraparound, the
protection that `struct_size()` adds against potential integer overflows
is defeated. Fix this by hardening call to `struct_size()` with `size_mul()`.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Herbert Xu <herbert@gondor.apana.org.au>
[ Upstream commit 8d338c76f7cfe0eb4bc46078b1c09c8c5fc75353 ]
The crypto_async_request passed to the completion is not guaranteed
to be the original request object. Only the data field can be relied
upon.
Fix this by storing the socket pointer with the AEAD request.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Baochen Qiang <quic_bqiang@quicinc.com>
[ Upstream commit 39564b475ac5a589e6c22c43a08cbd283c295d2c ]
Commit 5b32b6dd96633 ("ath11k: Remove core PCI references from
PCI common code") breaks with one MSI vector because it moves
affinity setting after IRQ request, see below log:
[ 1417.278835] ath11k_pci 0000:02:00.0: failed to receive control response completion, polling..
[ 1418.302829] ath11k_pci 0000:02:00.0: Service connect timeout
[ 1418.302833] ath11k_pci 0000:02:00.0: failed to connect to HTT: -110
[ 1418.303669] ath11k_pci 0000:02:00.0: failed to start core: -110
The detail is, if do affinity request after IRQ activated,
which is done in request_irq(), kernel caches that request and
returns success directly. Later when a subsequent MHI interrupt is
fired, kernel will do the real affinity setting work, as a result,
changs the MSI vector. However at that time host has configured
old vector to hardware, so host never receives CE or DP interrupts.
Fix it by setting affinity before registering MHI controller
where host is, for the first time, doing IRQ request.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Fietkau <nbd@nbd.name>
[ Upstream commit baa19b2e4b7bbb509a7ca7939c8785477dcd40ee ]
It turns out that the code in mt7603_rx_pse_busy() does not detect actual
hardware hangs, it only checks for busy conditions in PSE.
A reset should only be performed if these conditions are true and if there
is no rx activity as well.
Reset the counter whenever a rx interrupt occurs. In order to also deal with
a fully loaded CPU that leaves interrupts disabled with continuous NAPI
polling, also check for pending rx interrupts in the function itself.

[ Upstream commit c677dda165231c3efffb9de4bace249d5d2a51b9 ]
Only trigger PSE reset if PSE was stuck, otherwise it can cause DMA issues.
Trigger the PSE reset while DMA is fully stopped in order to improve
reliabilty.

[ Upstream commit 3176205933494bd184c6acd70e796c382bc729b5 ]
Before preparing the new beacon, check the queue status, flush out all
previous beacons and buffered multicast packets, then (if necessary)
try to recover more gracefully from a stuck beacon condition by making a
less invasive attempt at getting the MAC un-stuck.

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit 79bd60ee87e1136718a686d6617ced5de88ee350 ]
If an error occurs and channel_detector_exit() is called, it relies on
entries of the 'detectors' array to be NULL.
Otherwise, it may access to un-initialized memory.
Fix it and initialize the memory, as what was done before the commit in
Fixes.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
[ Upstream commit 046ece773cc77ef5d2a1431b188ac3d0840ed150 ]
In accordance with ACPI specificication and _DSD data buffer
representation the data there is an array of bytes. Hence,
accessing it with something longer will create a sparse data
which is against of how device property APIs work in general
and also not defined in the ACPI specification (see [1]).
Fix the code to emit an error if non-byte accessor is used to
retrieve _DSD buffer data.
Fixes: 369af6bf2c28 ("ACPI: property: Read buffer properties as integers")

From: Ondrej Zary <linux@zary.sk>
[ Upstream commit 35a341c9b25da6a479bd8013bcb11a680a7233e3 ]
Toshiba Portégé R100 has both acpi_video and toshiba_acpi vendor
backlight driver working. But none of them gets activated as it has
a VGA with no kernel driver (Trident CyberBlade XP4m32).
The DMI strings are very generic ("Portable PC") so add a custom
callback function to check for Trident CyberBlade XP4m32 PCI device
before enabling the vendor backlight driver (better than acpi_video
as it has more brightness steps).

From: Aditya Kumar Singh <quic_adisi@quicinc.com>
[ Upstream commit 77f1ee6fd8b6e470f721d05a2e269039d5cafcb7 ]
Tx power is fetched from firmware's pdev stats. However, during active
CAC, firmware does not fill the current Tx power and sends the max
initialised value filled during firmware init. If host sends this power
to user space, this is wrong since in certain situations, the Tx power
could be greater than the max allowed by the regulatory. Hence, host
should not be fetching the Tx power during an active CAC.
Fix this issue by returning -EAGAIN error so that user space knows that there's
no valid value available.

From: Marc Kleine-Budde <mkl@pengutronix.de>
[ Upstream commit fe5c9940dfd8ba0c73672dddb30acd1b7a11d4c7 ]
During testing, I triggered a can_restart() with the netif carrier
being OK [1]. The BUG_ON, which checks if the carrier is OK, results
in a fatal kernel crash. This is neither helpful for debugging nor for
a production system.
[1] The root cause is a race condition in can_restart() which will be
fixed in the next patch.
Do not crash the kernel, issue an error message instead, and continue
restarting the CAN device anyway.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Kleine-Budde <mkl@pengutronix.de>
[ Upstream commit 6841cab8c4504835e4011689cbdb3351dec693fd ]
This race condition was discovered while updating the at91_can driver
to use can_bus_off(). The following scenario describes how the
converted at91_can driver would behave.
When a CAN device goes into BUS-OFF state, the driver usually
stops/resets the CAN device and calls can_bus_off().
This function sets the netif carrier to off, and (if configured by
user space) schedules a delayed work that calls can_restart() to
restart the CAN device.
The can_restart() function first checks if the carrier is off and
triggers an error message if the carrier is OK.
Then it calls the driver's do_set_mode() function to restart the
device, then it sets the netif carrier to on. There is a race window
between these two calls.
The at91 CAN controller (observed on the sama5d3, a single core 32 bit
ARM CPU) has a hardware limitation. If the device goes into bus-off
while sending a CAN frame, there is no way to abort the sending of
this frame. After the controller is enabled again, another attempt is
made to send it.
If the bus is still faulty, the device immediately goes back to the
bus-off state. The driver calls can_bus_off(), the netif carrier is
switched off and another can_restart is scheduled. This occurs within
the race window before the original can_restart() handler marks the
netif carrier as OK. This would cause the 2nd can_restart() to be
called with an OK netif carrier, resulting in an error message.
The flow of the 1st can_restart() looks like this:
can_restart()
// bail out if netif_carrier is OK
netif_carrier_ok(dev)
priv->do_set_mode(dev, CAN_MODE_START)
// enable CAN controller
// sama5d3 restarts sending old message
// CAN devices goes into BUS_OFF, triggers IRQ
// IRQ handler start
at91_irq()
at91_irq_err_line()
can_bus_off()
netif_carrier_off()
schedule_delayed_work()
// IRQ handler end
netif_carrier_on()
The 2nd can_restart() will be called with an OK netif carrier and the
error message will be printed.
To close the race window, first set the netif carrier to on, then
restart the controller. In case the restart fails with an error code,
roll back the netif carrier to off.

------------------
From: Felipe Negrelli Wolter <felipe.negrelliwolter@silabs.com>
[ Upstream commit ea2274ab0b18549dbf0e755e41d8c5e8b5232dc3 ]
When frames are sent over the air, the device always applies the data
rates in descending order. The driver assumed Minstrel also provided
rate in descending order.
However, in some cases, Minstrel can a choose a fallback rate greater
than the primary rate. In this case, the two rates was inverted, the
device try highest rate first and we get many retries.
Since the device always applies rates in descending order, the
workaround is to drop the rate when it higher than its predecessor in

This patch has been tested in isolated room with a series of
attenuators. Here are the Minstrel statistics with 80dBm of attenuation:

We can notice the device try now to send with lower rates (and high
success rates). At the end, we measured 20-25% better throughput with
this patch.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Juhee Kang <claudiajkang@gmail.com>
[ Upstream commit 4b6c6065fca123d419afef005a696f51e6590470 ]
The open code is defined as a helper function(tp_to_dev) on r8169_main.c,
which the open code is &tp->pci_dev->dev. The helper function was added
in commit 1e1205b7d3e9 ("r8169: add helper tp_to_dev"). And then later,
commit f1e911d5d0df ("r8169: add basic phylib support") added
r8169_phylink_handler function but it didn't use the helper function.
Thus, tp_to_dev() replaces the open code. This patch doesn't change logic.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiner Kallweit <hkallweit1@gmail.com>
[ Upstream commit 621735f590643e3048ca2060c285b80551660601 ]
In very rare cases (I've seen two reports so far about different
RTL8125 chip versions) it seems the MAC locks up when link goes down
and requires a software reset to get revived.
Realtek doesn't publish hw errata information, therefore the root cause
is unknown. Realtek vendor drivers do a full hw re-initialization on
each link-up event, the slimmed-down variant here was reported to fix
the issue for the reporting user.
It's not fully clear which parts of the NIC are reset as part of the
software reset, therefore I can't rule out side effects.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xin Long <lucien.xin@gmail.com>
[ Upstream commit cf791b22bef7d9352ff730a8727d3871942d6001 ]
This patch adds a test case to reproduce the SCTP DATA chunk retransmission
timeout issue caused by the improper SCTP collision processing in netfilter
nf_conntrack_proto_sctp.
In this test, client sends a INIT chunk, but the INIT_ACK replied from
server is delayed until the server sends a INIT chunk to start a new
connection from its side. After the connection is complete from server
side, the delayed INIT_ACK arrives in nf_conntrack_proto_sctp.
The delayed INIT_ACK should be dropped in nf_conntrack_proto_sctp instead
of updating the vtag with the out-of-date init_tag, otherwise, the vtag
in DATA chunks later sent by client don't match the vtag in the conntrack
entry and the DATA chunks get dropped.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Phil Sutter <phil@nwl.cc>
[ Upstream commit c4eee56e14fe001e1cff54f0b438a5e2d0dd7454 ]
Assume that caller's 'to' offset really represents an upper boundary for
the pattern search, so patterns extending past this offset are to be
rejected.
The old behaviour also was kind of inconsistent when it comes to
fragmentation (or otherwise non-linear skbs): If the pattern started in
between 'to' and 'from' offsets but extended to the next fragment, it
was not found if 'to' offset was still within the current fragment.
Test the new behaviour in a kselftest using iptables' string match.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 73ed8e03388d16c12fc577e5c700b58a29045a15 ]
cookie_init_timestamp() is supposed to return a 64bit timestamp
suitable for both TSval determination and setting of skb->tstamp.
Unfortunately it uses 32bit fields and overflows after
2^32 * 10^6 nsec (~49 days) of uptime.
Generated TSval are still correct, but skb->tstamp might be set
far away in the past, potentially confusing other layers.
tcp_ns_to_ts() is changed to return a full 64bit value,
ts and ts_now variables are changed to u64 type,
and TSMASK is removed in favor of shifts operations.
While we are at it, change this sequence:
ts >>= TSBITS;
ts--;
ts <<= TSBITS;
ts |= options;
to:
ts -= (1UL << TSBITS);

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gregory Greenman <gregory.greenman@intel.com>
[ Upstream commit 5af2bb3168db6b0af9988eb25cccf2e3bc4455e2 ]
When rx/tx queues are being freed, on a different CPU there could be
still rx flow running. Call napi_synchronize() to prevent such a race.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit 37fb29bd1f90f16d1abc95c0e9f0ff8eec9829ad ]
When we want to synchronize the NAPI, which was added in
commit 5af2bb3168db ("wifi: iwlwifi: call napi_synchronize()
before freeing rx/tx queues"), we also need to make sure we
can't actually reschedule the NAPI. Yes, this happens while
interrupts are disabled, but interrupts may still be running
or pending. Also call iwl_pcie_synchronize_irqs() to ensure
we won't reschedule the NAPI.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miri Korenblit <miriam.rachel.korenblit@intel.com>
[ Upstream commit 658939fc68d3241f9a0019e224cd7154438c23f2 ]
If a TX queue has no space for new TX frames, the driver will keep
these frames in the overflow queue, and during reclaim flow it
will retry to send the frames from that queue.
But if the reclaim flow was invoked from TX queue flush, we will also
TX these frames, which is wrong as we don't want to TX anything
after flush.
This might also cause assert 0x125F when removing the queue,
saying that the driver removes a non-empty queue
Fix this by TXing the overflow queue's frames only if we are
not in flush queue flow.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Song Liu <song@kernel.org>
[ Upstream commit d35381aa73f7e1e8b25f3ed5283287a64d9ddff5 ]
htab_lock_bucket uses the following logic to avoid recursion:
1. preempt_disable();
2. check percpu counter htab->map_locked[hash] for recursion;
2.1. if map_lock[hash] is already taken, return -BUSY;
3. raw_spin_lock_irqsave();
However, if an IRQ hits between 2 and 3, BPF programs attached to the IRQ
logic will not able to access the same hash of the hashtab and get -EBUSY.
This -EBUSY is not really necessary. Fix it by disabling IRQ before
checking map_locked:
1. preempt_disable();
2. local_irq_save();
3. check percpu counter htab->map_locked[hash] for recursion;
3.1. if map_lock[hash] is already taken, return -BUSY;
4. raw_spin_lock().
Similarly, use raw_spin_unlock() and local_irq_restore() in
htab_unlock_bucket().

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit 48cf49d31994ff97b33c4044e618560ec84d35fb ]
snprintf() does not return negative values on error.
To know if the buffer was too small, the returned value needs to be
compared with the length of the passed buffer. If it is greater or
equal, the output has been truncated, so add checks for the truncation
to create_pnp_modalias() and create_of_modalias(). Also make them
return -ENOMEM in that case, as they already do that elsewhere.
Moreover, the remaining size of the buffer used by snprintf() needs to
be updated after the first write to avoid out-of-bounds access as
already done correctly in create_pnp_modalias(), but not in
create_of_modalias(), so change the latter accordingly.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yan Zhai <yan@cloudflare.com>
[ Upstream commit 03d6c848bfb406e9ef6d9846d759e97beaeea113 ]
When the ipv6 stack output a GSO packet, if its gso_size is larger than
dst MTU, then all segments would be fragmented. However, it is possible
for a GSO packet to have a trailing segment with smaller actual size
than both gso_size as well as the MTU, which leads to an "atomic
fragment". Atomic fragments are considered harmful in RFC-8021. An
Existing report from APNIC also shows that atomic fragments are more
likely to be dropped even it is equivalent to a no-op [1].
Add an extra check in the GSO slow output path. For each segment from
the original over-sized packet, if it fits with the path MTU, then avoid
generating an atomic fragment.

------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit ff672b9ffeb3f82135488ac16c5c5eb4b992999b ]
Both ipvlan_process_v4_outbound() and ipvlan_process_v6_outbound()
increment dev->stats.tx_errors in case of errors.
Unfortunately there are two issues :
1) ipvlan_get_stats64() does not propagate dev->stats.tx_errors to user.
2) Increments are not atomic. KCSAN would complain eventually.
Use DEV_STATS_INC() to not miss an update, and change ipvlan_get_stats64()
to copy the value back to user.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Konrad Dybcio <konrad.dybcio@linaro.org>
[ Upstream commit 4afda5f6bcdf673ef2556fcfa458daf3a5a648d8 ]
The GCC driver contains clocks that are owned (meaning configured and
scaled) by the RPM core.
Remove them from Linux to stop interjecting the RPM's logic.
Fixes: b1e010c0730a ("clk: qcom: Add MSM8996 Global Clock Control (GCC) driver")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Devi Priya <quic_devipriy@quicinc.com>
[ Upstream commit f7b7d30158cff246667273bd2a62fc93ee0725d2 ]
If the parent clock rate is greater than unsigned long max/2 then
integer overflow happens when calculating the clock rate on 32-bit systems.
As RCG2 uses half integer dividers, the clock rate is first being
multiplied by 2 which will overflow the unsigned long max value.
Hence, replace the common pattern of doing 64-bit multiplication
and then a do_div() call with simpler mult_frac call.

From: Konrad Dybcio <konrad.dybcio@linaro.org>
[ Upstream commit 9906c4140897bbdbff7bb71c6ae67903cb9954ce ]
Some branch clocks are governed externally and we're only supposed to
send a request concerning their shutdown, not actually ensure it happens.
Use the BRANCH_HALT_SKIP define to skip checking the halt bit.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen-Yu Tsai <wenst@chromium.org>
[ Upstream commit 7442edec72bc657e6ce38ae01de9f10e55decfaa ]
The MT6358 and MT6366 PMICs, and likely many others from MediaTek, have
a chip ID register, making the chip semi-discoverable.
The driver currently supports two PMICs and expects to be probed on one
or the other. It does not account for incorrect mfd driver entries or
device trees. While these should not happen, if they do, it could be
catastrophic for the device. The driver should be sure the hardware is
what it expects.
Make the driver fail to probe if the chip ID presented is not a known
one.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robert Chiras <robert.chiras@nxp.com>
[ Upstream commit 15cee75dacb82ade710d61bfd536011933ef9bf2 ]
Move the elcdif_pll clock initialization before the lcd_clk, since the
elcdif_clk needs to be initialized ahead of lcd_clk, being its parent.
This change fixes issues with the LCD clocks during suspend/resume.

[ Upstream commit d5252d9697a3e7007c741e9c103073868955a304 ]
The clock dividers might be used with clock stop bit enabled or not.
Current tables only support recommended values from the datasheet. This
might result in warnings like below because no valid clock divider is
found. Resulting in a 0 divider.
There are Renesas ARM Trusted Firmware version out there which e.g.
configure 0x201 (shifted logical right by 2: 0x80) and with this match
the added { STPnHCK | 0, 1 }:

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
[ Upstream commit d2692ed490e680a41401cef879adebcfafb4298f ]
The SD MUX output (SD0) is further divided by 4 in G2{L,UL}. The
divided clock is SD0_DIV4. SD0_DIV4 is registered with
CLK_SET_RATE_PARENT which means a rate request for it is propagated to
the MUX and could reach rzg2l_cpg_sd_clk_mux_set_parent() concurrently
with the users of SD0.
Add proper locking to avoid concurrent accesses on SD MUX set rate
registers.

[ Upstream commit bf51d3b2d048c312764a55d91d67a85ee5535e31 ]
The onitial value of the CPG_PL2SDHI_DSEL bits 0..1 or 4..6 is 01b. The
hardware user's manual (r01uh0914ej0130-rzg2l-rzg2lc.pdf) specifies that
setting 0 is prohibited. Hence rzg2l_cpg_sd_clk_mux_get_parent() should
just read CPG_PL2SDHI_DSEL, trust the value, and return the proper clock
parent index based on the value read.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
[ Upstream commit a2b23159499efd36b2d63b3c4534075d12ddc97a ]
According to the hardware manual for RZ/G2L
(r01uh0914ej0130-rzg2l-rzg2lc.pdf), the computation formula for PLL rate
is as follows:
Fout = ((m + k/65536) * Fin) / (p * 2^s)
and k has values in the range [-32768, 32767]. Dividing k by 65536 with
integer arithmetic gives zero all the time, causing slight differences
b/w what has been set vs. what is displayed. Thus, get rid of this and
decompose the formula before dividing k by 65536.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dario Binacchi <dario.binacchi@amarulasolutions.com>
[ Upstream commit 3400d546a741a2b2001d88e7fa29110d45a3930d ]
The ti_clk_register() and ti_clk_register_omap_hw() functions are always
called with the parameter of type "struct device" set to NULL, since the
functions from which they are called always have a parameter of type
"struct device_node". Replacing "struct device" type parameter with
"struct device_node" will allow you to register a TI clock to the common
clock framework by taking advantage of the facilities provided by the
"struct device_node" type. Further, adding the "of_" prefix to the name
of these functions explicitly binds them to the "struct device_node"
type.
The patch has been tested on a Beaglebone board.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit ed85891a276edaf7a867de0e9acd0837bc3008f2 ]
When a WMI device besides the first one somehow fails to register,
retval is returned while still containing a negative error code. This
causes the ACPI device fail to probe, leaving behind zombie WMI devices
leading to various errors later.
Handle the single error path separately and return 0 unconditionally
after trying to register all WMI devices to solve the issue. Also
continue to register WMI devices even if some fail to allocate memory.

From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit eba9ac7abab91c8f6d351460239108bef5e7a0b6 ]
Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via
file private data"), the miscdevice stores a pointer to itself inside
filp->private_data, which means that private_data will not be NULL when
wmi_char_open() is called. This might cause memory corruption should
wmi_char_open() be unable to find its driver, something which can
happen when the associated WMI device is deleted in wmi_free_devices().
Fix the problem by using the miscdevice pointer to retrieve the WMI
device data associated with a char device using container_of(). This
also avoids wmi_char_open() picking a wrong WMI device bound to a
driver with the same name as the original driver.

When build with W=1 and "-Werror=format-truncation", below error is

Given that
1. '%d' could take 10 charactors,
2. '%s' could take 10 charactors ("crit_alarm"),
3. "temp", "_" and the NULL terminator take 6 charactors,
fix the problem by increasing CORETEMP_NAME_LENGTH to 28.

From: Guenter Roeck <linux@roeck-us.net>
[ Upstream commit 28da9dee3594423534f3ea1e1f61e6bb2d2fa651 ]
This reverts commit fd2d53c367ae9983c2100ac733a834e0c79d7537.
As reported by Ian Nartowicz, this and the preceding patch
result in a failure to load the driver on Celsius W280.
While the alternative would be to add the board to the DMI
override table, it is quite likely that other systems are
also affected. Revert the offending patches to avoid future
problems.

Use bit macros then accessing SCH5627_REG_CTRL, so that people
do not need to look at the datasheet to find out what each bit
does.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit 7da8a635436029957c5350da3acf51d78ed64071 ]
When the lock bit inside SCH5627_REG_CTRL is set, then the virtual
registers become read-only until the next power cycle.
Disallow write access to those registers in such a case.
Tested on a Fujitsu Esprimo P720.

[ Upstream commit 342f7e4967d02b0ec263b15916304fc54841b608 ]
It's possible for users to try to duplicate the CRTC state even when the
state doesn't exist. drm_atomic_helper_crtc_duplicate_state() (and other
users of __drm_atomic_helper_crtc_duplicate_state()) already guard this
with a WARN_ON() instead of crashing, so let's do that here too.

From: Stefan Eichenberger <stefan.eichenberger@toradex.com>
[ Upstream commit 3b0a01a6a5224ed9b3f69f44edaa889b2e2b9779 ]
Enable hot plug detection when it is available on the HDMI port.
Without this connecting to a different monitor with incompatible timing
before the 10 seconds poll period will lead to a broken display output.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 941882a0e96d245f38116e940912b404b6a93c6f ]
The driver calls lt8912_bridge_detach() from its lt8912_remove()
function. As the DRM core detaches bridges automatically, this leads to
calling lt8912_bridge_detach() twice. The code probably has tried to
manage the double-call with the 'is_attached' variable, but the driver
never sets the variable to false, so its of no help.
Fix the issue by dropping the call to lt8912_bridge_detach() from
lt8912_remove(), as the DRM core will handle the detach call for us,
and also drop the useless is_attached field.

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 44283993144a03af9df31934d6c32bbd42d1a347 ]
The lt8912b driver, in its bridge detach function, calls
drm_connector_unregister() and drm_connector_cleanup().
drm_connector_unregister() should be called only for connectors
explicitly registered with drm_connector_register(), which is not the
case in lt8912b.
The driver's drm_connector_funcs.destroy hook is set to
drm_connector_cleanup().
Thus the driver should not call either drm_connector_unregister() nor
drm_connector_cleanup() in its lt8912_bridge_detach(), as they cause a
crash on bridge detach:

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 6985c5efc4057bc79137807295d84ada3123d051 ]
lt8912b only calls drm_bridge_hpd_enable() if it creates a connector and
the next bridge has DRM_BRIDGE_OP_HPD set. However, when calling
drm_bridge_hpd_disable() it misses checking if a connector was created,
calling drm_bridge_hpd_disable() even if HPD was never enabled. I don't
see any issues caused by this wrong call, though.
Add the check to avoid wrongly calling drm_bridge_hpd_disable().

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit a2d9036615f0adfa5b0a46bb2ce42ef1d9a04fbe ]
smatch reports:
drivers/gpu/drm/bridge/tc358768.c:223 tc358768_update_bits() error: uninitialized symbol 'orig'.
Fix this by bailing out from tc358768_update_bits() if the
tc358768_read() produces an error.

------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 66962d5c3c51377b9b90cae35b7e038950438e02 ]
The driver has a few places where it does:
if (thing_is_enabled_in_config)
update_thing_bit_in_hw()
This means that if the thing is _not_ enabled, the bit never gets
cleared. This affects the h/vsyncs and continuous DSI clock bits.
Fix the driver to always update the bit.

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit e5fb21678136a9d009d5c43821881eb4c34fae97 ]
The TC358768 documentation uses HFP, HBP, etc. values to deal with the
video mode, while the driver currently uses the DRM display mode
(htotal, hsync_start, etc).
Change the driver to convert the DRM display mode to struct videomode,
which then allows us to use the same units the documentation uses. This
makes it much easier to work on the code when using the TC358768
documentation as a reference.

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 013ea98cdfccef3b7c38b087c1f629488d2ef683 ]
The driver debug prints DSI related timings as raw register values in
hex. It is much more useful to see the "logical" value of the timing,
not the register value.
Change the prints to print the values separately, in case a single
register contains multiple values, and use %u to have it in a more human
consumable form.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 699cf62a7d4550759f4a50e614b1952f93de4783 ]
The Toshiba documentation talks about HSByteClk when referring to the
DSI HS byte clock, whereas the driver uses 'dsibclk' name. Also, in a
few places the driver calculates the byte clock from the DSI clock, even
if the byte clock is already available in a variable.
To align the driver with the documentation, change the 'dsibclk'
variable to 'hsbyteclk'. This also make it easier to visually separate
'dsibclk' and 'dsiclk' variables.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit b3aa7b34924a9ed64cf96899cac4d8ea08cd829e ]
The driver defines TC358768_PRECISION as 1000, and uses "nsk" to refer
to clock periods. The original author does not remember where all this
came from. Effectively the driver is using picoseconds as the unit for
clock periods, yet referring to them by "nsk".
Clean this up by just saying the periods are in picoseconds.

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit f1dabbe645065d20ca863c8d446c74c59ca1ca9d ]
The tc358768_ns_to_cnt() is, most likely, supposed to do a div-round-up
operation, but it misses subtracting one from the dividend.
Fix this by just using DIV_ROUND_UP().

------------------
From: Xiaogang Chen <xiaogang.chen@amd.com>
[ Upstream commit 7bfaa160caed8192f8262c4638f552cad94bcf5a ]
This patch fixes:
1: ref number of prange's svm_bo got decreased by an async call from hmm. When
wait svm_bo of prange got released we shoul also wait prang->svm_bo become NULL,
otherwise prange->svm_bo may be set to null after allocate new vram buffer.
2: During waiting svm_bo of prange got released in a while loop should reschedule
current task to give other tasks oppotunity to run, specially the the workque
task that handles svm_bo ref release, otherwise we may enter to softlock.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michel Dänzer <mdaenzer@redhat.com>
[ Upstream commit 003048ddf44b1a6cfa57afa5a0cf40673e13f1ba ]
It was only checking planes which had any state changes in the same
commit. However, it also needs to check other enabled planes.
Not doing this meant that a commit might spuriously "succeed", resulting
in the cursor plane displaying with incorrect scaling. See
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3177#note_1824263
for an example.

From: Michel Dänzer <mdaenzer@redhat.com>
[ Upstream commit bc0b79ce2050aa523c38c96b6d26340a96bfbdca ]
If no plane was newly enabled or changed scaling, there can be no new
scaling mismatch with the cursor plane.
By not pulling non-cursor plane states into all atomic commits while
the cursor plane is enabled, this avoids synchronizing all cursor plane
changes to vertical blank, which caused the following IGT tests to fail:
kms_cursor_legacy@cursor-vs-flip.*
kms_cursor_legacy@flip-vs-cursor.*

From: Gabriel Krisman Bertazi <krisman@suse.de>
[ Upstream commit ab69838e7c75b0edb699c1a8f42752b30333c46f ]
Commit 3851d25c75ed0 ("io_uring: check for rollover of buffer ID when
providing buffers") introduced a check to prevent wrapping the BID
counter when sqe->off is provided, but it's off-by-one too
restrictive, rejecting the last possible BID (65534).
i.e., the following fails with -EINVAL.
io_uring_prep_provide_buffers(sqe, addr, size, 0xFFFF, 0, 0);

nbufs tracks the number of buffers and not the last bgid. In 16-bit, we
have 2^16 valid buffers, but the check mistakenly rejects the last
bid. Let's fix it to make the interface consistent with the

From: Jason-JH.Lin <jason-jh.lin@mediatek.com>
[ Upstream commit 3ec71e05ae6e7f46512e568ed81c92be589003dd ]
According to the comment in drm_atomic_helper_async_commit(),
we should make sure FBs have been swapped, so that cleanups in the
new_state performs a cleanup in the old FB.
So we should move swapping FBs after calling mtk_plane_update_new_state(),
to avoid using the old FB which could be freed.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jason-JH.Lin <jason-jh.lin@mediatek.com>
[ Upstream commit 53412dc2905401207f264dc30890f6b9e41524a6 ]
The difference between drm_atomic_helper_commit_tail() and
drm_atomic_helper_commit_tail_rpm() is
drm_atomic_helper_commit_tail() will commit plane first and
then enable crtc, drm_atomic_helper_commit_tail_rpm() will
enable crtc first and then commit plane.
Before mediatek-drm enables crtc, the power and clk required
by OVL have not been turned on, so the commit plane cannot be
committed before crtc is enabled. That means OVL layer should
not be enabled before crtc is enabled.
Therefore, the atomic_commit_tail of mediatek-drm is hooked with
drm_atomic_helper_commit_tail_rpm().
Another reason is that the plane_state of drm_atomic_state is not
synchronized with the plane_state stored in mtk_crtc during crtc enablng,
so just set all planes to disabled.

[ Upstream commit 44b968d0d0868b7a9b7a5c64464ada464ff4d532 ]
cdn_dp_audio_codec_init() can fail. So add some error handling.
If component_add() fails, the previous cdn_dp_audio_codec_init() call
should be undone, as already done in the remove function.

If DSI host attachment fails, the LT9611UXC driver will remove the
bridge without ensuring that there is no outstanding HPD work being
done. In rare cases this can result in the warnings regarding the mutex
being incorrect. Fix this by forcebly freing IRQ and flushing the work.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Rutland <mark.rutland@arm.com>
[ Upstream commit 20f3b8eafe0ba5d3c69d5011a9b07739e9645132 ]
When KPTI is in use, we cannot register a runstate region as XEN
requires that this is always a valid VA, which we cannot guarantee. Due
to this, xen_starting_cpu() must avoid registering each CPU's runstate
region, and xen_guest_init() must avoid setting up features that depend
upon it.
We tried to ensure that in commit:
f88af7229f6f22ce (" xen/arm: do not setup the runstate info page if kpti is enabled")
... where we added checks for xen_kernel_unmapped_at_usr(), which wraps
arm64_kernel_unmapped_at_el0() on arm64 and is always false on 32-bit
arm.
Unfortunately, as xen_guest_init() is an early_initcall, this happens
before secondary CPUs are booted and arm64 has finalized the
ARM64_UNMAP_KERNEL_AT_EL0 cpucap which backs
arm64_kernel_unmapped_at_el0(), and so this can subsequently be set as
secondary CPUs are onlined. On a big.LITTLE system where the boot CPU
does not require KPTI but some secondary CPUs do, this will result in
xen_guest_init() intializing features that depend on the runstate
region, and xen_starting_cpu() registering the runstate region on some
CPUs before KPTI is subsequent enabled, resulting the the problems the
aforementioned commit tried to avoid.
Handle this more robsutly by deferring the initialization of the
runstate region until secondary CPUs have been initialized and the
ARM64_UNMAP_KERNEL_AT_EL0 cpucap has been finalized. The per-cpu work is
moved into a new hotplug starting function which is registered later
when we're certain that KPTI will not be used.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@linaro.org>
[ Upstream commit 6471da5ee311d53ef46eebcb7725bc94266cc0cf ]
The "ret" variable is declared as ssize_t and it can hold negative error
codes but the "rk_obj->base.size" variable is type size_t. This means
that when we compare them, they are both type promoted to size_t and the
negative error code becomes a high unsigned value and is treated as
success. Add a cast to fix this.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com>
[ Upstream commit 2c269f42d0f382743ab230308b836ffe5ae9b2ae ]
Linux enables MSI-X before disabling INTx, but keeps MSI-X masked until
the table is filled. Then it disables INTx just before clearing MASKALL
bit. Currently this approach is rejected by xen-pciback.
According to the PCIe spec, device cannot use INTx when MSI/MSI-X is
enabled (in other words: enabling MSI/MSI-X implicitly disables INTx).
Change the logic to consider INTx disabled if MSI/MSI-X is enabled. This
applies to three places:
- checking currently enabled interrupts type,
- transition to MSI/MSI-X - where INTx would be implicitly disabled,
- clearing INTx disable bit - which can be allowed even if MSI/MSI-X is
enabled, as device should consider INTx disabled anyway in that case

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
[ Upstream commit 5e05be78264594634860087953649487f486ffcc ]
If the drm/msm init code gets an error during output modeset
initialisation, the kernel will report an error regarding DRM memory
manager not being clean during shutdown. This is because
msm_dsi_modeset_init() allocates a piece of GEM memory for the TX
buffer, but destruction of the buffer happens only at
msm_dsi_host_destroy(), which is called during DSI driver's remove()
time, much later than the DRM MM shutdown.
To solve this issue, move the TX buffer destruction to dsi_unbind(), so
that the buffer is destructed at the correct time. Note, we also have to
store a reference to the address space, because priv->kms->aspace is
cleared before components are unbound.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andre Przywara <andre.przywara@arm.com>
[ Upstream commit 851354cbd12bb9500909733c3d4054306f61df87 ]
The AppliedMicro XGene-1 CPU has an erratum where the timer condition
would only consider TVAL, not CVAL. We currently apply a workaround when
seeing the PartNum field of MIDR_EL1 being 0x000, under the assumption
that this would match only the XGene-1 CPU model.
However even the Ampere eMAG (aka XGene-3) uses that same part number, and
only differs in the "Variant" and "Revision" fields: XGene-1's MIDR is
0x500f0000, our eMAG reports 0x503f0002. Experiments show the latter
doesn't show the faulty behaviour.
Increase the specificity of the check to only consider partnum 0x000 and
variant 0x00, to exclude the Ampere eMAG.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>
[ Upstream commit 5855d422a6f250f3518f43b49092c8e87a5e42be ]
Due to the initial confusion about MIPI_DSI_MODE_EOT_PACKET, properly
renamed to MIPI_DSI_MODE_NO_EOT_PACKET, reflecting its actual meaning,
both the DSI_TXRX_CON register setting for bit (HSTX_)DIS_EOT and the
later calculation for horizontal sync-active (HSA), back (HBP) and
front (HFP) porches got incorrect due to the logic being inverted.
This means that a number of settings were wrong because....:
- DSI_TXRX_CON register setting: bit (HSTX_)DIS_EOT should be
set in order to disable the End of Transmission packet;
- Horizontal Sync and Back/Front porches: The delta used to
calculate all of HSA, HBP and HFP should account for the
additional EOT packet.
Before this change...
- Bit (HSTX_)DIS_EOT was being set when EOT packet was enabled;
- For HSA/HBP/HFP delta... all three were wrong, as words were
added when EOT disabled, instead of when EOT packet enabled!
Invert the logic around flag MIPI_DSI_MODE_NO_EOT_PACKET in the
MediaTek DSI driver to fix the aforementioned issues.

From: Hao Chen <chenhao418@huawei.com>
[ Upstream commit 50b560783f7f71790bcf70e9e9855155fb0af8c1 ]
When tearing down a 'hisi_hns3' PMU, we mistakenly run the CPU hotplug
callbacks after the device has been unregistered, leading to fireworks
when we try to execute empty function callbacks within the driver:
| Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000

Use cpuhp_state_remove_instance_nocalls() instead of
cpuhp_state_remove_instance() so that the notifiers don't execute after
the PMU device has been unregistered.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robin Murphy <robin.murphy@arm.com>
[ Upstream commit 7819e05a0dceac20c5ff78ec9b252faf3b76b824 ]
CMN implements a set of CoreSight-format peripheral ID registers which
in principle we should be able to use to identify the hardware. However
so far we have avoided trying to use the part number field since the
TRMs have all described it as "configuration dependent". It turns out,
though, that this is a quirk of the documentation generation process,
and in fact the part number should always be a stable well-defined field
which we can trust.
To that end, revamp our model detection to rely less on ACPI/DT, and
pave the way towards further using the hardware information as an
identifier for userspace jevent metrics. This includes renaming the
revision constants to maximise readability.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robin Murphy <robin.murphy@arm.com>
[ Upstream commit e3e73f511c49c741f6309862c2248958ad77bbaa ]
It transpires that dtm_unit_info is another register which got shuffled
in CMN-700 without me noticing. Fix that in a way which also proactively
fixes the fragile laziness of its consumer, just in case any further
fields ever get added alongside dtc_domain.

------------------
From: Yicong Yang <yangyicong@hisilicon.com>
[ Upstream commit 6d7d51e88e21c0af1ca96a3617afef334bfeffcf ]
Check whether the event type matches the PMU type firstly in
pmu::event_init() before touching the event. Otherwise we'll
change the events of others and lead to incorrect results.
Since in perf_init_event() we may call every pmu's event_init()
in a certain case, we should not modify the event if it's not
ours.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Junhao He <hejunhao3@huawei.com>
[ Upstream commit b805cafc604bfdb671fae7347a57f51154afa735 ]
When we fail to register the uncore pmu, the pmu context may not been
allocated. The error handing will call cpuhp_state_remove_instance()
to call uncore pmu offline callback, which migrate the pmu context.
Since that's liable to lead to some kind of use-after-free.
Use cpuhp_state_remove_instance_nocalls() instead of
cpuhp_state_remove_instance() so that the notifiers don't execute after
the PMU device has been failed to register.

Usually there is only one llcc device. But if there were a second, even
a failed probe call would modify the global drv_data pointer. So check
if drv_data is valid before overwriting it.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dhruva Gole <d-gole@ti.com>
[ Upstream commit 7b7a224b1ba1703583b25a3641ad9798f34d832a ]
The TI-SCI message protocol provides a way to communicate between
various compute processors with a central system controller entity. It
provides the fundamental device management capability and clock control
in the SOCs that it's used in.
The remove function failed to do all the necessary cleanup if
there are registered users. Some things are freed however which
likely results in an oops later on.
Ensure that the driver isn't unbound by suppressing its bind and unbind
sysfs attributes. As the driver is built-in there is no way to remove
device once bound.
We can also remove the ti_sci_remove call along with the
ti_sci_debugfs_destroy as there are no callers for it any longer.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sudeep Holla <sudeep.holla@arm.com>
[ Upstream commit 7d0bc6360f17ea323ab25939a34857123d7d87e5 ]
Commit 19b8766459c4 ("firmware: arm_ffa: Fix FFA device names for logical
partitions") added an ID to the FFA device using ida_alloc() and append
the same to "arm-ffa" to make up a unique device name. However it missed
to stash the id value in ffa_dev to help freeing the ID later when the
device is destroyed.
Due to the missing/unassigned ID in FFA device, we get the following
warning when the FF-A device is unregistered.
| ida_free called for id=0 which is not allocated.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sudeep Holla <sudeep.holla@arm.com>
[ Upstream commit 2d698e8b4fd22374dac0a2d5150ab24d57a222ab ]
An FF-A ABI could support both the SMC32 and SMC64 conventions.
A callee that runs in the AArch64 execution state and implements such
an ABI must implement both SMC32 and SMC64 conventions of the ABI.
So the FF-A drivers will need the option to choose the mode irrespective
of FF-A version and the partition execution mode flag in the partition
information.
Let us remove the check on the FF-A version for allowing the selection
of 32bit mode of messaging. The driver will continue to set the 32-bit
mode if the partition execution mode flag specified that the partition
supports only 32-bit execution.
Fixes: 106b11b1ccd5 ("firmware: arm_ffa: Set up 32bit execution mode flag using partiion property")

The pinmux for LED3 and LED4 are incorrectly attached to the
omap3_pmx_core when they should be connected to the omap3_pmx_wkup
pin mux. This was likely masked by the fact that the bootloader
used to do all the pinmuxing.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thierry Reding <treding@nvidia.com>
[ Upstream commit c0b80988eb78d6423249ab530bfbc6b238790a26 ]
The shared interrupts 0-9 of the TKE are mapped to interrupts 0-9, but
shared interrupts 10-15 are mapped to 256-261. Correct the mapping for
the final 6 interrupts. This prevents the TKE from requesting the RTC
interrupt (along with several GTE and watchdog interrupts).
Reported-by: Shubhi Garg <shgarg@nvidia.com>

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej Wieczor-Retman <maciej.wieczor-retman@intel.com>
[ Upstream commit 4d7f4e8158b62f63031510cdc24acc520956c091 ]
Compiling pidfd selftest after adding a __printf() attribute to
ksft_print_msg() and ksft_test_result_pass() exposes -Wformat warnings
in error_report(), test_pidfd_poll_exec_thread(),
child_poll_exec_test(), test_pidfd_poll_leader_exit_thread(),
child_poll_leader_exit_test().
The ksft_test_result_pass() in error_report() expects a string but
doesn't provide any argument after the format string. All the other
calls to ksft_print_msg() in the functions mentioned above have format
strings that don't match with other passed arguments.
Fix format specifiers so they match the passed variables.
Add a missing variable to ksft_test_result_pass() inside
error_report() so it matches other cases in the switch statement.

From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
[ Upstream commit 4a28c7665c2a1ac0400864eabb0c641e135f61aa ]
Benchmark command is copied into an array in the stack. The array is
BENCHMARK_ARGS items long but the command line could try to provide a
longer command. Argument size is also fixed by BENCHMARK_ARG_SIZE (63
bytes of space after fitting the terminating \0 character) and user
could have inputted argument longer than that.
Return error in case the benchmark command does not fit to the space
allocated for it.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrea Righi <andrea.righi@canonical.com>
[ Upstream commit 3737df782c740b944912ed93420c57344b1cf864 ]
Use a similar approach as commit a419beac4a07 ("module/decompress: use
vmalloc() for zstd decompression workspace") and replace kmalloc() with
vmalloc() also for the gzip module decompression workspace.
In this case the workspace is represented by struct inflate_workspace
that can be fairly large for kmalloc() and it can potentially lead to
allocation errors on certain systems:
$ pahole inflate_workspace
struct inflate_workspace {
struct inflate_state inflate_state; /* 0 9544 */
/* --- cacheline 149 boundary (9536 bytes) was 8 bytes ago --- */
unsigned char working_window[32768]; /* 9544 32768 */
/* size: 42312, cachelines: 662, members: 2 */
/* last cacheline: 8 bytes */
};
Considering that there is no need to use continuous physical memory,
simply switch to vmalloc() to provide a more reliable in-kernel module
decompression.

[ Upstream commit 9f8948db9849d202dee3570507d3a0642f92d632 ]
The interrupt handler invokes pm_runtime_get_sync() without checking the

Add a proper verification and switch to pm_runtime_resume_and_get(), to
avoid the need to call pm_runtime_put_noidle() for decrementing the PM
usage counter before returning from the error condition.

From: Cristian Ciocaltea <cristian.ciocaltea@collabora.com>
[ Upstream commit 2d5661e6008ae1a1cd6df7cc844908fb8b982c58 ]
According to the documentation, drivers are responsible for undoing at
removal time all runtime PM changes done during probing.
Hence, add the missing calls to pm_runtime_dont_use_autosuspend(), which
are necessary for undoing pm_runtime_use_autosuspend().
Note this would have been handled implicitly by
devm_pm_runtime_enable(), but there is a need to continue using
pm_runtime_enable()/pm_runtime_disable() in order to ensure the runtime
PM is disabled as soon as the remove() callback is entered.

If component_add() fails, probe() returns without calling
pm_runtime_put(), which leaves the runtime PM usage counter incremented.
Fix the issue by jumping to err_pm label and drop the now unnecessary
pm_runtime_disable() call.

[ Upstream commit 85a1bf86fac0c195929768b4e92c78cad107523b ]
According to the documentation, drivers are responsible for undoing at
removal time all runtime PM changes done during probing.
Hence, add the missing calls to pm_runtime_dont_use_autosuspend(), which
are necessary for undoing pm_runtime_use_autosuspend().

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Wahren <wahrenst@gmx.net>
[ Upstream commit b58a36008bfa1aadf55f516bcbfae40c779eb54b ]
The last RCU stall fix caused a massive throughput regression of the
hwrng on Raspberry Pi 0 - 3. hwrng_msleep doesn't sleep precisely enough
and usleep_range doesn't allow scheduling. So try to restore the
best possible throughput by introducing hwrng_yield which interruptable
sleeps for one jiffy.
Some performance measurements on Raspberry Pi 3B+ (arm64/defconfig):
sudo dd if=/dev/hwrng of=/dev/null count=1 bs=10000
cpu_relax ~138025 Bytes / sec
hwrng_msleep(1000) ~13 Bytes / sec
hwrng_yield ~2510 Bytes / sec
Fixes: 96cb9d055445 ("hwrng: bcm2835 - use hwrng_msleep() instead of cpu_relax()")

6.1-stable review patch. If anyone has any objections, please let me know.

From: Jonas Gorski <jonas.gorski@gmail.com>
[ Upstream commit 464bd8ec2f06707f3773676a1bd2c64832a3c805 ]
When the membase and pci_dev pointer were moved to a new struct in priv,
the actual membase users were left untouched, and they started reading
out arbitrary memory behind the struct instead of registers. This
unfortunately turned the RNG into a constant number generator, depending
on the content of what was at that offset.
To fix this, update geode_rng_data_{read,present}() to also get the
membase via amd_geode_priv, and properly read from the right addresses
again.

[ Upstream commit 81760bedc65194ff38e1e4faefd5f9f0c95c19a4 ]
If, for any reason, the open-coded arithmetic causes a wraparound,
the protection that `struct_size()` provides against potential integer
overflows is defeated. Fix this by hardening calls to `struct_size()`
with `size_add()`, `size_sub()` and `size_mul()`.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit 9c20cb8b1847dedddec3d5163079290542bf00bf ]
If the device is already in the up state, a subsequent write of `up` to
the sysfs attribute /sys/bus/pci/devices/<BDF>/qat/state brings the
device down.
Fix this behaviour by ignoring subsequent `up` commands if the device is
already in the up state.
Fixes: 1bdc85550a2b ("crypto: qat - fix concurrency issue when device state changes")

From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit e9612987e437b7ada686f472c7596686fabecb2b ]
Move the logic that maps, unmaps and converts scatterlists into QAT
bufferlists from qat_algs.c to a new module, qat_bl.
This is to allow reuse of the logic by the data compression service.
This commit does not implement any functional change.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit b0cd997f35598c4fc01bf22061e1eb88fc10afad ]
Rename the functions qat_alg_sgl_to_bufl() and qat_alg_free_bufl() as
qat_bl_sgl_to_bufl() and qat_bl_free_bufl() after their relocation into
the qat_bl module.
This commit does not implement any functional change.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit 3ed330d0dba61d2e08a0eed7aa3d5def3f0c749b ]
The functions qat_alg_sgl_to_bufl() and qat_alg_free_bufl() take as
argument a qat_crypto_instance and a qat_crypto_request structure.
These two structures are used only to get a reference to the
adf_accel_dev and qat_crypto_request_buffs.
In order to reuse these functions for the compression service, change
the signature so that they take adf_accel_dev and
qat_crypto_request_buffs.

From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit 36ebc7472afeb58f1eb1d4c1f0546b9e98acea46 ]
The structure qat_crypto_request_buffs which contains the source and
destination buffer lists and correspondent sizes and dma addresses is
also required for the compression service.
Rename it as qat_request_buffs and move it to qat_bl.h.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit cf692906bd61af2eec06a32a83d2a8ec3acf3548 ]
The compression service requires an additional pre-allocated buffer for
each destination scatter list.
Extend the function qat_alg_sgl_to_bufl() to take an additional
structure that contains the dma address and the size of the extra
buffer which will be appended in the destination FW SGL.
The logic that unmaps buffers in qat_alg_free_bufl() has been changed to
start unmapping from buffer 0 instead of skipping the initial buffers
num_buff - num_mapped_bufs as that functionality was not used in the
code.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit 9b2f33a1bfcda90b857431a764c9c8f9a412bbe5 ]
The function adf_dev_init(), through the subsystem qat_crypto, populates
the list of list of crypto instances accel_dev->crypto_list.
If the list of instances is not empty, the function adf_dev_start() will
then call qat_algs_registers() and qat_asym_algs_register() to register
the crypto algorithms into the crypto framework.
If any of the functions in adf_dev_start() fail, the caller of such
function, in the error path calls adf_dev_down() which in turn call
adf_dev_stop() and adf_dev_shutdown(), see for example the function
state_store in adf_sriov.c.
However, if the registration of crypto algorithms is not done,
adf_dev_stop() will try to unregister the algorithms regardless.
This might cause the counter active_devs in qat_algs.c and
qat_asym_algs.c to get to a negative value.
Add a new state, ADF_STATUS_CRYPTO_ALGS_REGISTERED, which tracks if the
crypto algorithms are registered into the crypto framework. Then use
this to unregister the algorithms if such flag is set. This ensures that
the crypto algorithms are only unregistered if previously registered.

codes for RTAS and hypercalls are not the same.
Fix this issue by restoring the use of H_BUSY and H_IS_LONG_BUSY().

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomas Glozar <tglozar@redhat.com>
[ Upstream commit 36c75ce3bd299878fd9b238e9803d3817ddafbf3 ]
nd_region_acquire_lane uses get_cpu, which disables preemption. This is
an issue on PREEMPT_RT kernels, since btt_write_pg and also
nd_region_acquire_lane itself take a spin lock, resulting in BUG:
sleeping function called from invalid context.
Fix the issue by replacing get_cpu with smp_process_id and
migrate_disable when needed. This makes BTT operations preemptible, thus
permitting the use of spin_lock.
BUG example occurring when running ndctl tests on PREEMPT_RT kernel:
BUG: sleeping function called from invalid context at
kernel/locking/spinlock_rt.c:48
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 4903, name:

[ Upstream commit 5827e17d0555b566c32044b0632b46f9f95054fa ]
vmd_domain_reset() attempts to find whether the device may contain multiple
functions by checking 0x80 (Multi-Function Device), however, the hdr_type
variable has already been masked with PCI_HEADER_TYPE_MASK so the check can
never true.
To fix the issue, don't mask the read with PCI_HEADER_TYPE_MASK.

From: Danny Kaehn <danny.kaehn@plexus.com>
[ Upstream commit e3c2d2d144c082dd71596953193adf9891491f42 ]
Previously the cp2112 driver called INIT_DELAYED_WORK within
cp2112_gpio_irq_startup, resulting in duplicate initilizations of the
workqueue on subsequent IRQ startups following an initial request. This
resulted in a warning in set_work_data in workqueue.c, as well as a rare
NULL dereference within process_one_work in workqueue.c.
Initialize the workqueue within _probe instead.

------------------
From: Kai Ye <yekai13@huawei.com>
[ Upstream commit 7bbbc9d81be588ae4fb28b5b202e4421dbfef197 ]
There is no security data in the pointer. It is only a value transferred
as a structure. It makes no sense to zero a variable that is on the stack.
So not need to set the pointer to null.

From: Kai Ye <yekai13@huawei.com>
[ Upstream commit b40b62ed7b0ffe8eb2e6fe8bcfb47027c9a93e93 ]
The last register logic and different register logic are combined.
Use "u32" instead of 'int' in the regs function input parameter to
simplify some checks.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kai Ye <yekai13@huawei.com>
[ Upstream commit 94476b2b6d60bc926a585ae62e1bf69bd22c1dff ]
Considering that the qm feature and debugfs feature are independent.
The code related to debugfs is getting larger and larger. It should be
separate as a debugfs file. So move some debugfs code to new file from
qm file. The qm code logic is not modified. And maintainability is
enhanced.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Longfang Liu <liulongfang@huawei.com>
[ Upstream commit 5831fc1fd4a578232fea708b82de0c666ed17153 ]
If the queue isolation feature is enabled, the number of queues
supported by the device changes. When PF is enabled using the
current default number of queues, the default number of queues may
be greater than the number supported by the device. As a result,
the PF fails to be bound to the driver.
After modification, if queue isolation feature is enabled, when
the default queue parameter is greater than the number supported
by the device, the number of enabled queues will be changed to
the number supported by the device, so that the PF and driver
can be properly bound.
Fixes: 8bbecfb402f7 ("crypto: hisilicon/qm - add queue isolation support for Kunpeng930")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kursad Oney <kursad.oney@broadcom.com>
[ Upstream commit c0e824661f443b8cab3897006c1bbc69fd0e7bc4 ]
memset() description in ISO/IEC 9899:1999 (and elsewhere) says:
The memset function copies the value of c (converted to an
unsigned char) into each of the first n characters of the
object pointed to by s.
The kernel's arm32 memset does not cast c to unsigned char. This results
in the following code to produce erroneous output:
char a[128];
memset(a, -128, sizeof(a));
This is because gcc will generally emit the following code before
it calls memset() :
mov r0, r7
mvn r1, #127 ; 0x7f
bl 00000000 <memset>
r1 ends up with 0xffffff80 before being used by memset() and the
'a' array will have -128 once in every four bytes while the other
bytes will be set incorrectly to -1 like this (printing the first
8 bytes) :
test_module: -128 -1 -1 -1
test_module: -1 -1 -1 -128
The change here is to 'and' r1 with 255 before it is used.

From: Patrisious Haddad <phaddad@nvidia.com>
[ Upstream commit c1336bb4aa5e809a622a87d74311275514086596 ]
Previously when we had a RAW QP, we bound a counter to it when it moved
to INIT state, using the counter context inside RQC.
But when we try to modify that counter later in RTS state we used
modify QP which tries to change the counter inside QPC instead of RQC.
Now we correctly modify the counter set_id inside of RQC instead of QPC
for the RAW QP.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chengchang Tang <tangchengchang@huawei.com>
[ Upstream commit 9faef73ef4f6666b97e04d99734ac09251098185 ]
The current driver will print all asynchronous events. Some of the
print levels are set improperly, e.g. SRQ limit reach and SRQ last
wqe reach, which may also occur during normal operation of the software.
Currently, the information of these event is printed as a warning,
which causes a large amount of printing even during normal use of the
application. As a result, the service performance deteriorates.
This patch fixes the printing storms by modifying the print level.

------------------
From: Chengchang Tang <tangchengchang@huawei.com>
[ Upstream commit c64e9710f9241e38a1c761ed1c1a30854784da66 ]
ucmd in hns_roce_create_qp_common() are not initialized. But it works fine
until new member sdb_addr is added to struct hns_roce_ib_create_qp.
If the user-mode driver uses an old version ABI, then the value of the new
member will be undefined after ib_copy_from_udata().
This patch fixes it by initialize this variable to 0. And the default value
of the new member sdb_addr will be 0 which is invalid.

From: Chengchang Tang <tangchengchang@huawei.com>
[ Upstream commit b5f9efff101b06fd06a5e280a2b00b1335f5f476 ]
The ib_mtu_enum_to_int() and uverbs_attr_get_len() may returns a negative
value. In this case, mixed comparisons of signed and unsigned types will
throw wrong results.
This patch adds judgement for this situation.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
[ Upstream commit f549a82aff57865c47b5abd17336b23cd9bb2d2c ]
In an effort to not call sof_ops_free twice, we stopped running it when
probe was aborted.
Check the result of cancel_work_sync to see if this was the case.

[ Upstream commit 9e630efb5a4af56fdb15aa10405f5cfd3f5f5b83 ]
The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context. We fix it by calling
pm_runtime_disable when error returns.

------------------
From: Daniel Mentz <danielmentz@google.com>
[ Upstream commit a75a16c62a2540f11eeae4f2b50e95deefb652ea ]
utf16s_to_utf8s does not NULL terminate the output string. For us to be
able to add a NULL character when utf16s_to_utf8s returns, we need to make
sure that there is space for such NULL character at the end of the output
buffer. We can achieve this by passing an output buffer size to
utf16s_to_utf8s that is one character less than what we allocated.
Other call sites of utf16s_to_utf8s appear to be using the same technique
where they artificially reduce the buffer size by one to leave space for a
NULL character or line feed character.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Danny Kaehn <danny.kaehn@plexus.com>
[ Upstream commit dc3115e6c5d9863ec1a9ff1acf004ede93c34361 ]
Previously cp2112_gpio_irq_shutdown() always cancelled the
gpio_poll_worker, even if other IRQs were still active, and did not set
the gpio_poll flag to false. This resulted in any call to _shutdown()
resulting in interrupts no longer functioning on the chip until a
_remove() occurred (a.e. the cp2112 is unplugged or system rebooted).
Only cancel polling if all IRQs are disabled/masked, and correctly set
the gpio_poll flag, allowing polling to restart when an interrupt is
next enabled.

[ Upstream commit 553f7ac78fbb41b2c93ab9b9d78e42274d27daa9 ]
The SuperH BIOS earlyprintk code is protected by CONFIG_EARLY_PRINTK.
However, when this protection was added, it was missed that SuperH no
longer defines an EARLY_PRINTK config symbol since commit
e76fe57447e88916 ("sh: Remove old early serial console code V2"), so
BIOS earlyprintk can no longer be used.
Fix this by reviving the EARLY_PRINTK config symbol.

From: Bastien Nocera <hadess@hadess.net>
[ Upstream commit cae253d6033da885e71c29c1591b22838a52de76 ]
Now that we're in 2022, and the majority of desktop environments can and
should support touchpad gestures through libinput, remove the legacy
module parameter that made it possible to use gestures implemented in
firmware.
This will eventually allow simplifying the driver's initialisation code.
This reverts commit 9188dbaed68a4b23dc96eba165265c08caa7dc2a.

HIDPP_QUIRK_NO_HIDINPUT isn't used by any devices but still happens to
work as HIDPP_QUIRK_DELAYED_INIT is defined to the same value. Remove
HIDPP_QUIRK_NO_HIDINPUT and use HIDPP_QUIRK_DELAYED_INIT everywhere
instead.
Tested on a T650 which requires that quirk, and a number of unifying and
Bluetooth devices that don't.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 11ca0322a41920df2b462d2e45b0731e47ff475b ]
Restarting IO causes 2 problems:
1. Some devices do not like IO being restarted this was addressed in
commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary"), but that change has issues of its own and needs to
be reverted.
2. Restarting IO and specifically calling hid_device_io_stop() causes
received packets to be missed, which may cause connect-events to
get missed.
Restarting IO was introduced in commit 91cf9a98ae41 ("HID: logitech-hidpp:
make .probe usbhid capable") to allow to retrieve the device's name and
serial number and store these in hdev->name and hdev->uniq before
connecting any hid subdrivers (hid-input, hidraw) exporting this info
to userspace.
But this does not require restarting IO, this merely requires deferring
calling hid_connect(). Calling hid_hw_start() with a connect-mask of
0 makes it skip calling hid_connect(), so hidpp_probe() can simply call
hid_connect() later without needing to restart IO.
Remove the stop + restart of IO and instead just call hid_connect() later
to avoid the issues caused by restarting IO.
Now that IO is no longer stopped, hid_hw_close() must be called at the end
of probe() to balance the hid_hw_open() done at the beginning probe().

------------------
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 55bf70362ffc4ddd7c8745e2fe880edac00e4aff ]
Commit 91cf9a98ae41 ("HID: logitech-hidpp: make .probe usbhid capable")
makes hidpp_probe() first call hid_hw_start(hdev, 0) to allow IO
without connecting any hid subdrivers (hid-input, hidraw).
This is done to allow to retrieve the device's name and serial number
and store these in hdev->name and hdev->uniq.
Then later on IO was stopped and started again with hid_hw_start(hdev,
HID_CONNECT_DEFAULT) connecting hid-input and hidraw after the name
and serial number have been setup.
Commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary") changed the probe() code to only do the start with
a 0 connect-mask + restart later for unifying devices.
But for non unifying devices hdev->name and hdev->uniq are updated too.
So this change re-introduces the problem for which the start with
a 0 connect-mask + restart later behavior was introduced.
The previous patch in this series changes the unifying path to instead of
restarting IO only call hid_connect() later. This avoids possible issues
with restarting IO seen on non unifying devices.
Revert the change to limit the restart behavior to unifying devices to
fix hdev->name changing after userspace facing devices have already been
registered.

From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit ba9de350509504fb748837b71e23d7e84c83d93c ]
Calling get_wireless_feature_index() from probe() causes
the wireless_feature_index to only get set for unifying devices which
are already connected at probe() time. It does not get set for devices
which connect later.
Fix this by moving get_wireless_feature_index() to hidpp_connect_event(),
this does not make a difference for devices connected at probe() since
probe() will queue the hidpp_connect_event() for those at probe time.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: WangJinchao <wangjinchao@xfusion.com>
[ Upstream commit 7ddc21e317b360c3444de3023bcc83b85fabae2f ]
In a high-load arm64 environment, the pcrypt_aead01 test in LTP can lead
to system UAF (Use-After-Free) issues. Due to the lengthy analysis of
the pcrypt_aead01 function call, I'll describe the problem scenario
using a simplified model:
Suppose there's a user of padata named `user_function` that adheres to
the padata requirement of calling `padata_free_shell` after `serial()`
has been invoked, as demonstrated in the following code:
```c
struct request {
struct padata_priv padata;
struct completion *done;
};
void parallel(struct padata_priv *padata) {
do_something();
}
void serial(struct padata_priv *padata) {
struct request *request = container_of(padata,
struct request,
padata);
complete(request->done);
}
void user_function() {
DECLARE_COMPLETION(done)
padata->parallel = parallel;
padata->serial = serial;
padata_do_parallel();
wait_for_completion(&done);
padata_free_shell();
}
```
In the corresponding padata.c file, there's the following code:
```c
static void padata_serial_worker(struct work_struct *serial_work) {
...
cnt = 0;
while (!list_empty(&local_list)) {
...
padata->serial(padata);
cnt++;
}
local_bh_enable();
if (refcount_sub_and_test(cnt, &pd->refcnt))
padata_free_pd(pd);
}
```
Because of the high system load and the accumulation of unexecuted
softirq at this moment, `local_bh_enable()` in padata takes longer
to execute than usual. Subsequently, when accessing `pd->refcnt`,
`pd` has already been released by `padata_free_shell()`, resulting
in a UAF issue with `pd->refcnt`.
The fix is straightforward: add `refcount_dec_and_test` before calling
`padata_free_pd` in `padata_free_shell`.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
[ Upstream commit 203b01001c4d741205b9c329acddc5193ed56fbd ]
If a request has the flag CRYPTO_TFM_REQ_MAY_BACKLOG set, the function
qat_alg_send_message_maybacklog(), enqueues it in a backlog list if
either (1) there is already at least one request in the backlog list, or
(2) the HW ring is nearly full or (3) the enqueue to the HW ring fails.
If an interrupt occurs right before the lock in qat_alg_backlog_req() is
taken and the backlog queue is being emptied, then there is no request
in the HW queues that can trigger a subsequent interrupt that can clear
the backlog queue. In addition subsequent requests are enqueued to the
backlog list and not sent to the hardware.
Fix it by holding the lock while taking the decision if the request
needs to be included in the backlog queue or not. This synchronizes the
flow with the interrupt handler that drains the backlog queue.
For performance reasons, the logic has been changed to try to enqueue
first without holding the lock.

From: George Kennedy <george.kennedy@oracle.com>
[ Upstream commit 2ef422f063b74adcc4a4a9004b0a87bb55e0a836 ]
In the unlikely event that workqueue allocation fails and returns NULL in
mlx5_mkey_cache_init(), delete the call to
mlx5r_umr_resource_cleanup() (which frees the QP) in
mlx5_ib_stage_post_ib_reg_umr_init(). This will avoid attempted double
free of the same QP when __mlx5_ib_add() does its cleanup.
Resolves a splat:

From: Herve Codina <herve.codina@bootlin.com>
[ Upstream commit 7ba7bdef4d14e3722e2842da3b48cbadb73e52d6 ]
The loop searching for a matching device based on its compatible
string is aborted when a matching disabled device is found.
This abort prevents to add devices as soon as one disabled device
is found.
Continue searching for an other device instead of aborting on the
first disabled one fixes the issue.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen-Yu Tsai <wenst@chromium.org>
[ Upstream commit 61fdd1f1d2c183ec256527d16d75e75c3582af82 ]
The MT6366 PMIC is mostly, but not fully, compatible with MT6358. It has
a different set of regulators. Specifically, it lacks the camera related
VCAM* LDOs and VLDO28, but has additional VM18, VMDDR, and VSRAM_CORE LDOs.
The PMICs contain a chip ID register that can be used to detect which
exact model is preset, so it is possible to share a common base
compatible string.
Add a separate compatible for the MT6366 PMIC, with a fallback to the
MT6358 PMIC.

From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 831d1af85133e1763d41e20414912d9a1058ea72 ]
Commit 9e86b2ad4c11 changed the channel used for HPDET detection
(headphones vs lineout detection) from being hardcoded to
ARIZONA_ACCDET_MODE_HPL (HP left channel) to it being configurable
through arizona_pdata.hpdet_channel the DT/OF parsing added for
filling arizona_pdata on devicetree platforms ensures that
arizona_pdata.hpdet_channel gets set to ARIZONA_ACCDET_MODE_HPL
when not specified in the devicetree-node.
But on ACPI platforms where arizona_pdata is filled by
arizona_spi_acpi_probe() arizona_pdata.hpdet_channel was not
getting set, causing it to default to 0 aka ARIZONA_ACCDET_MODE_MIC.
This causes headphones to get misdetected as line-out on some models.
Fix this by setting hpdet_channel = ARIZONA_ACCDET_MODE_HPL.

The mutex locking is unnecessary here. The I2C transfers are guarded by

cause an emulated SMBUS transfer,
- i2c_master_send(), which causes an ordinary I2C transfer.
The Turris Omnia MCU LED controller is not semantically SMBUS, it
operates as a simple I2C bus. It does not implement any of the SMBUS
specific features, like PEC, or procedure calls, or anything. Moreover
the I2C controller driver also does not implement SMBUS, and so the
emulated SMBUS procedure from drivers/i2c/i2c-core-smbus.c is used for
the SMBUS calls, which gives an unnecessary overhead.
When I first wrote the driver, I was unaware of these facts, and I
simply used the first function that worked.
Drop the I2C SMBUS calls and instead use simple I2C transfers.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
[ Upstream commit 76fe464c8e64e71b2e4af11edeef0e5d85eeb6aa ]
Disabling a PWM (i.e. calling pwm_apply_state with .enabled = false)
gives no guarantees what the PWM output does. It might freeze where it
currently is, or go in a High-Z state or drive the active or inactive
state, it might even continue to toggle.
To ensure that the LED gets really disabled, don't disable the PWM even
when .duty_cycle is zero.
This fixes disabling a leds-pwm LED on i.MX28. The PWM on this SoC is
one of those that freezes its output on disable, so if you disable an
LED that is full on, it stays on. If you disable a LED with half
brightness it goes off in 50% of the cases and full on in the other 50%.

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit ff50f53276131a3059e8307d11293af388ed2bcd ]
In order to teach the compiler that 'trig->name' will never be truncated,
we need to tell it that 'cpu' is not negative.
When building with W=1, this fixes the following warnings:

VISIBLE_IF_KUNIT - A macro that sets symbols to be static if CONFIG_KUNIT
is not enabled. Otherwise if CONFIG_KUNIT is enabled there is no change to
the symbol definition.
EXPORT_SYMBOL_IF_KUNIT(symbol) - Exports symbol into

------------------
From: Rae Moar <rmoar@google.com>
[ Upstream commit b11e51dd70947107fa4076c6286dce301671afc1 ]
Use macros, VISIBLE_IF_KUNIT and EXPORT_SYMBOL_IF_KUNIT, to allow
static symbols to be conditionally set to be visible during
apparmor_policy_unpack_test, which removes the need to include the testing
file in the implementation file.
Change the namespace of the symbols that are now conditionally visible (by
adding the prefix aa_) to avoid confusion with symbols of the same name.
Allow the test to be built as a module and namespace the module name from
policy_unpack_test to apparmor_policy_unpack_test to improve clarity of
the module name.
Provide an example of how static symbols can be dealt with in testing.

From: Georgia Garcia <georgia.garcia@canonical.com>
[ Upstream commit 8884ba07786c718771cf7b78cb3024924b27ec2b ]
profile->disconnected was storing an invalid reference to the
disconnected path. Fix it by duplicating the string using
aa_unpack_strdup and freeing accordingly.
Fixes: 72c8a768641d ("apparmor: allow profiles to provide info to disconnected paths")

The issue was the use of testing a cpumap with NULL rather than using
empty, as a map containing the dummy value isn't NULL and the -1
results in an empty aggr map being allocated which legitimately
overflows when any member is accessed.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jinjie Ruan <ruanjinjie@huawei.com>
[ Upstream commit 9979cc64853b598518a485c2e554657d5c7a00c8 ]
The devm_clk_get_enabled() helper:
- calls devm_clk_get()
- calls clk_prepare_enable() and registers what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
Also replace devm_regulator_get() and regulator_enable() with
devm_regulator_get_enable() helper and remove regulator_disable().
Replace iio_device_register() with devm_iio_device_register() and remove
iio_device_unregister().
And st->reg is not used anymore, so remove it.
As Jonathan pointed out, couple of things that are wrong:
1) The device is powered down 'before' we unregister it with the
subsystem and as such userspace interfaces are still exposed which
probably won't do the right thing if the chip is powered down.
2) This isn't done in the error paths in probe.
To solve this problem, register a new callback adf4350_power_down()
with devm_add_action_or_reset(), to enable software power down in both
error and device detach path. So the remove function can be removed.
Remove spi_set_drvdata() from the probe function, since spi_get_drvdata()
is not used anymore.

1. Atoms are managed in page mode and should be released using atom_free()
instead of free().
2. When the event does not match, the atom needs to free.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vishal Moola (Oracle) <vishal.moola@gmail.com>
[ Upstream commit 247f9e1feef4e57911510c8f82348efb4491ea0e ]
This is the equivalent of find_get_pages_range_tag(), except for folios
instead of pages.
One noteable difference is filemap_get_folios_tag() does not take in a
maximum pages argument. It instead tries to fill a folio batch and stops
either once full (15 folios) or reaching the end of the search range.
The new function supports large folios, the initial function did not since
all callers don't use large folios.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vishal Moola (Oracle) <vishal.moola@gmail.com>
[ Upstream commit 1cd98ee747cff120ee9b93988ddb7315d8d8f8e7 ]
Convert the function to use a folio_batch instead of pagevec. This is in
preparation for the removal of find_get_pages_range_tag().
Also modified f2fs_all_cluster_page_ready to take in a folio_batch instead
of pagevec. This does NOT support large folios. The function currently
only utilizes folios of size 1 so this shouldn't cause any issues right
now.
This version of the patch limits the number of pages fetched to
F2FS_ONSTACK_PAGES. If that ever happens, update the start index here
since filemap_get_folios_tag() updates the index to be after the last
found folio, not necessarily the last used page.

The reason is f2fs_all_cluster_page_ready() assumes that pages array should
cover at least one cluster, otherwise, it will always return false, result
in deadloop.
By default, pages array size is 16, and it can cover the case cluster_size
is equal or less than 16, for the case cluster_size is larger than 16, let's
allocate memory of pages array dynamically.

we hit cached page in compress_inode's cache, dic may be released, it needs
break the loop rather than continuing it, in order to avoid accessing
invalid dic pointer.

tty_signal_session_leader(), which caused this leakage.
The pid memleak is triggered by the following race:

}
The issue is believed to be introduced by commit c8bcd9c5be24 ("tty:
Fix ->session locking") who moves the unlock of siglock in
disassociate_ctty() above "if (tty)", making a small window allowing
tty_signal_session_leader() to kick in. It can be easily reproduced by
adding a delay before "if (tty)" and at the entrance of
tty_signal_session_leader().
To fix this issue, we move "put_pid(current->signal->tty_old_pgrp)" after
"tty->ctrl.pgrp = NULL".

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Namhyung Kim <namhyung@kernel.org>
[ Upstream commit 0e501a65d35bf72414379fed0e31a0b6b81ab57d ]
The BTF func proto for a tracepoint has one more argument than the
actual tracepoint function since it has a context argument at the
begining. So it should compare to 5 when the tracepoint has 4
arguments.
typedef void (*btf_trace_sched_switch)(void *, bool, struct task_struct *, struct task_struct *, unsigned int);
Also, recent change in the perf tool would use a hand-written minimal
vmlinux.h to generate BTF in the skeleton. So it won't have the info
of the tracepoint. Anyway it should use the kernel's vmlinux BTF to
check the type in the kernel.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fenghua Yu <fenghua.yu@intel.com>
[ Upstream commit 88928addeec577386e8c83b48b5bc24d28ba97fd ]
idxd sub-drivers belong to bus dsa_bus_type. Thus, dsa_bus_type must be
registered in dsa bus init before idxd drivers can be registered.
But the order is wrong when both idxd and idxd_bus are builtin drivers.
In this case, idxd driver is compiled and linked before idxd_bus driver.
Since the initcall order is determined by the link order, idxd sub-drivers
are registered in idxd initcall before dsa_bus_type is registered
in idxd_bus initcall. idxd initcall fails:
[ 21.562803] calling idxd_init_module+0x0/0x110 @ 1
[ 21.570761] Driver 'idxd' was unable to register with bus_type 'dsa' because the bus was not initialized.
[ 21.586475] initcall idxd_init_module+0x0/0x110 returned -22 after 15717 usecs
[ 21.597178] calling dsa_bus_init+0x0/0x20 @ 1
To fix the issue, compile and link idxd_bus driver before idxd driver
to ensure the right registration order.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jia-Ju Bai <baijiaju@buaa.edu.cn>
[ Upstream commit ef307bc6ef04e8c1ea843231db58e3afaafa9fa6 ]
In _dwc2_hcd_urb_enqueue(), "urb->hcpriv = NULL" is executed without
holding the lock "hsotg->lock". In _dwc2_hcd_urb_dequeue():
spin_lock_irqsave(&hsotg->lock, flags);
...
if (!urb->hcpriv) {
dev_dbg(hsotg->dev, "## urb->hcpriv is NULL ##\n");
goto out;
}
rc = dwc2_hcd_urb_dequeue(hsotg, urb->hcpriv); // Use urb->hcpriv
...
out:
spin_unlock_irqrestore(&hsotg->lock, flags);
When _dwc2_hcd_urb_enqueue() and _dwc2_hcd_urb_dequeue() are
concurrently executed, the NULL check of "urb->hcpriv" can be executed
before "urb->hcpriv = NULL". After urb->hcpriv is NULL, it can be used
in the function call to dwc2_hcd_urb_dequeue(), which can cause a NULL
pointer dereference.
This possible bug is found by an experimental static analysis tool
developed by myself. This tool analyzes the locking APIs to extract
function pairs that can be concurrently executed, and then analyzes the
instructions in the paired functions to identify possible concurrency
bugs including data races and atomicity violations. The above possible
bug is reported, when my tool analyzes the source code of Linux 6.5.
To fix this possible bug, "urb->hcpriv = NULL" should be executed with
holding the lock "hsotg->lock". After using this patch, my tool never
reports the possible bug, with the kernelconfiguration allyesconfig for
x86_64. Because I have no associated hardware, I cannot test the patch
in runtime testing, and just verify it according to the code logic.

From: Michał Mirosław <mirq-linux@rere.qmqm.pl>
[ Upstream commit 7ab8716713c931ac79988f2592e1cf8b2e4fec1b ]
Tegra USB controllers seem to issue DMA in full 32-bit words only and thus
may overwrite unevenly-sized buffers. One such occurrence is detected by
SLUB when receiving a reply to a 1-byte buffer (below). Fix this by
allocating a bounce buffer also for buffers with sizes not a multiple of 4.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michał Mirosław <mirq-linux@rere.qmqm.pl>
[ Upstream commit 2ae61a2562c0d1720545b0845829a65fb6a9c2c6 ]
The USB host on Tegra3 works with 32-bit alignment. Previous code tried
to align the buffer, but it did align the wrapper struct instead, so
the buffer was at a constant offset of 8 bytes (two pointers) from
expected alignment. Since kmalloc() guarantees at least 8-byte
alignment already, the alignment-extending is removed.

From: Dan Carpenter <dan.carpenter@linaro.org>
[ Upstream commit 14f6d317913f634920a640e9047aa2e66f5bdcb7 ]
Zero is not a valid IRQ for in-kernel code and the irq_of_parse_and_map()
function returns zero on error. So this check for valid IRQs should only
accept values > 0.

[ Upstream commit 4d08c3d12b61022501989f9f071514d2d6f77c47 ]
It is not allowed to call kfree_skb() from hardware interrupt
context or with hardware interrupts being disabled.
So replace kfree_skb() with dev_kfree_skb_irq() under
spin_lock_irqsave(). Compile tested only.

------------------
From: Matti Vaittinen <mazziesaccount@gmail.com>
[ Upstream commit 2d3dff577dd0ea8fe9637a13822f7603c4a881c8 ]
The iio_generic_buffer can return garbage values when the total size of
scan data is not a multiple of the largest element in the scan. This can be
demonstrated by reading a scan, consisting, for example of one 4-byte and
one 2-byte element, where the 4-byte element is first in the buffer.
The IIO generic buffer code does not take into account the last two
padding bytes that are needed to ensure that the 4-byte data for next
scan is correctly aligned.
Add the padding bytes required to align the next sample with the scan size.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit 83c761f568733277ce1f7eb9dc9e890649c29a8c ]
If pxad_alloc_desc() fails on the first dma_pool_alloc() call, then
sw_desc->nb_desc is zero.
In such a case pxad_free_desc() is called and it will BUG_ON().
Remove this erroneous BUG_ON().
It is also useless, because if "sw_desc->nb_desc == 0", then, on the first
iteration of the for loop, i is -1 and the loop will not be executed.
(both i and sw_desc->nb_desc are 'int')

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

Move the const ignore_list definition out of the
of_count_icc_providers() function. This prevents the following stack
frame size warnings if the list is expanded:

__parse_fpscr() is called from two sites. First call is guarded

Second call is guarded by CONFIG_MATH_EMULATION which selects

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <masahiroy@kernel.org>
[ Upstream commit 7f54e00e5842663c2cea501bbbdfa572c94348a3 ]
When MODULE_DEVICE_TABLE(tee, ) is built on a host with a different
endianness from the target architecture, it results in an incorrect
MODULE_ALIAS().
For example, see a case where drivers/char/hw_random/optee-rng.c
is built as a module for ARM little-endian.
If you build it on a little-endian host, you will get the correct
MODULE_ALIAS:
$ grep MODULE_ALIAS drivers/char/hw_random/optee-rng.mod.c
MODULE_ALIAS("tee:ab7a617c-b8e7-4d8f-8301-d09b61036b64*");
However, if you build it on a big-endian host, you will get a wrong
MODULE_ALIAS:
$ grep MODULE_ALIAS drivers/char/hw_random/optee-rng.mod.c
MODULE_ALIAS("tee:646b0361-9bd0-0183-8f4d-e7b87c617aab*");
The same problem also occurs when you enable CONFIG_CPU_BIG_ENDIAN,
and build it on a little-endian host.
This issue has been unnoticed because the ARM kernel is configured for
little-endian by default, and most likely built on a little-endian host
(cross-build on x86 or native-build on ARM).
The uuid field must not be reversed because uuid_t is an array of __u8.
Fixes: 0fc1db9d1059 ("tee: add bus driver framework for TEE based devices")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <masahiroy@kernel.org>
[ Upstream commit ac96a15a0f0c8812a3aaa587b871cd5527f6d736 ]
When MODULE_DEVICE_TABLE(ishtp, ) is built on a host with a different
endianness from the target architecture, it results in an incorrect
MODULE_ALIAS().
For example, see a case where drivers/platform/x86/intel/ishtp_eclite.c
is built as a module for x86.
If you build it on a little-endian host, you will get the correct
MODULE_ALIAS:
$ grep MODULE_ALIAS drivers/platform/x86/intel/ishtp_eclite.mod.c
MODULE_ALIAS("ishtp:{6A19CC4B-D760-4DE3-B14D-F25EBD0FBCD9}");
However, if you build it on a big-endian host, you will get a wrong
MODULE_ALIAS:
$ grep MODULE_ALIAS drivers/platform/x86/intel/ishtp_eclite.mod.c
MODULE_ALIAS("ishtp:{BD0FBCD9-F25E-B14D-4DE3-D7606A19CC4B}");
This issue has been unnoticed because the x86 kernel is most likely built
natively on an x86 host.
The guid field must not be reversed because guid_t is an array of __u8.

------------------
From: Benjamin Gray <bgray@linux.ibm.com>
[ Upstream commit ff7a60ab1e065257a0e467c13b519f4debcd7fcf ]
Sparse reports a size mismatch in the endian swap. The Opal
implementation[1] passes the value as a __be64, and the receiving
variable out_qsize is a u64, so the use of be32_to_cpu() appears to be
an error.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Haren Myneni <haren@linux.ibm.com>
[ Upstream commit 73b25505ce043b561028e5571d84dc82aa53c2b4 ]
The VAS open window call prints error message and returns -EBUSY
after the migration suspend event initiated and until the resume
event completed on the destination system. It can cause the log
buffer filled with these error messages if the user space issues
continuous open window calls. Similar case even for DLPAR CPU
remove event when no credits are available until the credits are
freed or with the other DLPAR CPU add event.
So changes in the patch to use pr_err_ratelimited() instead of
pr_err() to display open window failure and not-available credits
error messages.
Use pr_fmt() and make the corresponding changes to have the
consistencein prefix all pr_*() messages (vas-api.c).

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Basavaraj Natikar <Basavaraj.Natikar@amd.com>
[ Upstream commit 4baf1218150985ee3ab0a27220456a1f027ea0ac ]
The AMD USB host controller (1022:43f7) isn't going into PCI D3 by default
without anything connected. This is because the policy that was introduced
by commit a611bf473d1f ("xhci-pci: Set runtime PM as default policy on all
xHC 1.2 or later devices") only covered 1.2 or later.
The 1.1 specification also has the same requirement as the 1.2
specification for D3 support. So expand the runtime PM as default policy
to all AMD 1.1 devices as well.
Fixes: a611bf473d1f ("xhci-pci: Set runtime PM as default policy on all xHC 1.2 or later devices")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sergey Shtylyov <s.shtylyov@omp.ru>
[ Upstream commit a5f928db59519a15e82ecba4ae3e7cbf5a44715a ]
If this driver enables the xHC clocks while resuming from sleep, it calls
clk_prepare_enable() without checking for errors and blithely goes on to
read/write the xHC's registers -- which, with the xHC not being clocked,
at least on ARM32 usually causes an imprecise external abort exceptions
which cause kernel oops. Currently, the chips for which the driver does
the clock dance on suspend/resume seem to be the Broadcom STB SoCs, based
on ARM32 CPUs, as it seems...
Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.

This crash is due to the clearing out the cxl_memdev's driver context
(@cxlds) before the subsystem is done with it. This is ultimately due to
the region(s), that this memdev is a member, being torn down and expecting
to be able to de-reference @cxlds, like here:
static int cxl_region_decode_reset(struct cxl_region *cxlr, int count)
...
if (cxlds->rcd)
goto endpoint_reset;
...
Fix it by keeping the driver context valid until memdev-device
unregistration, and subsequently the entire stack of related
dependencies, unwinds.

[ Upstream commit efb339a83368ab25de1a18c0fdff85e01c13a1ea ]
The PSP can return a "firmware error" code of -1 in circumstances where
the PSP has not actually been called. To make this protocol unambiguous,
name the value SEV_RET_NO_FW_CALL.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dionna Glaze <dionnaglaze@google.com>
[ Upstream commit 0144e3b85d7b42e8a4cda991c0e81f131897457a ]
The GHCB specification declares that the firmware error value for
a guest request will be stored in the lower 32 bits of EXIT_INFO_2. The
upper 32 bits are for the VMM's own error code. The fw_err argument to
snp_guest_issue_request() is thus a misnomer, and callers will need
access to all 64 bits.
The type of unsigned long also causes problems, since sw_exit_info2 is
u64 (unsigned long long) vs the argument's unsigned long*. Change this
type for issuing the guest request. Pass the ioctl command struct's error
field directly instead of in a local variable, since an incomplete guest
request may not set the error code, and uninitialized stack memory would
be written back to user space.
The firmware might not even be called, so bookend the call with the no
firmware call error and clear the error.
Since the "fw_err" field is really exitinfo2 split into the upper bits'
vmm error code and lower bits' firmware error code, convert the 64 bit
value to a union.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Williams <dan.j.williams@intel.com>
[ Upstream commit db10cb9b574675402bfd8fe1a31aafdd45b002df ]
CONFIG_DEBUG_SG highlights that get_{report,ext_report,derived_key)()}
are passing stack buffers as the @req_buf argument to
handle_guest_request(), generating a Call Trace of the following form:
WARNING: CPU: 0 PID: 1175 at include/linux/scatterlist.h:187 enc_dec_message+0x518/0x5b0 [sev_guest]
[..]
Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/26/2023
RIP: 0010:enc_dec_message+0x518/0x5b0 [sev_guest]
Call Trace:
<TASK>
[..]
handle_guest_request+0x135/0x520 [sev_guest]
get_ext_report+0x1ec/0x3e0 [sev_guest]
snp_guest_ioctl+0x157/0x200 [sev_guest]
Note that the above Call Trace was with the DEBUG_SG BUG_ON()s converted
to WARN_ON()s.
This is benign as long as there are no hardware crypto accelerators
loaded for the aead cipher, and no subsequent dma_map_sg() is performed
on the scatterlist. However, sev-guest can not assume the presence of
an aead accelerator nor can it assume that CONFIG_DEBUG_SG is disabled.
Resolve this bug by allocating virt_addr_valid() memory, similar to the
other buffers am @snp_dev instance carries, to marshal requests from
user buffers to kernel buffers.

From: Javier Carrasco <javier.carrasco.cruz@gmail.com>
[ Upstream commit 2be36c09b6b07306be33519e1aa70d2e2a2161bb ]
The current implementation passes PIN_IO_INTA_OUT (2) as a mask and
PIN_IO_INTAPM (GENMASK(1, 0)) as a value.
Swap the variables to assign mask and value the right way.
This error was first introduced with the alarm support. For better or
worse it worked as expected because 0x02 was applied as a mask to 0x03,
resulting 0x02 anyway. This will of course not work for any other value.

[ Upstream commit e3ea1b4847e49234e691c0d66bf030bd65bb7f2b ]
If device_register() returns error in pccardd(), it leads two issues:
1. The socket_released has never been completed, it will block
pcmcia_unregister_socket(), because of waiting for completion
of socket_released.
2. The device name allocated by dev_set_name() is leaked.
Fix this two issues by calling put_device() when device_register() fails.
socket_released can be completed in pcmcia_release_socket(), the name can
be freed in kobject_cleanup().

[ Upstream commit 402ab979b29126068e0b596b641422ff7490214c ]
As the comment of device_register() says, it should use put_device()
to give up the reference in the error path. Then, insofar resources
will be freed in pcmcia_release_dev(), the error path is no longer
needed. In particular, this means that the (previously missing) dropping
of the reference to &p_dev->function_config->ref is now handled by
pcmcia_release_dev().

[ Upstream commit 99e1241049a92dd3e9a90a0f91e32ce390133278 ]
Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically.
Therefore, it needs to be freed, which is done by the driver core for
us once all references to the device are gone. Therefore, move the
dev_set_name() call immediately before the call device_register(), which
either succeeds (then the freeing will be done upon subsequent remvoal),
or puts the reference in the error call. Also, it is not unusual that the
return value of dev_set_name is not checked.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Vasut <marex@denx.de>
[ Upstream commit 88d4b23a629ebd34f682f770cb6c2116c851f7b8 ]
The i.MX8MM/N/P does not define the .reset op since reset of the VPU is
done by genpd. Check whether the .reset op is defined before calling it
to avoid NULL pointer dereference.
Note that the Fixes tag is set to the commit which removed the reset op
from i.MX8M Hantro G2 implementation, this is because before this commit
all the implementations did define the .reset op.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Vasut <marex@denx.de>
[ Upstream commit 6e481d52d363218a3e6feb31694da74b38b30fad ]
In case of encoded input VP9 data width that is not multiple of macroblock
size, which is 16 (e.g. 1080x1920 frames, where 1080 is multiple of 8), the
width is padded to be a multiple of macroblock size (for 1080x1920 frames,
that is 1088x1920).
The hantro_postproc_g2_enable() checks whether the encoded data width is
equal to decoded frame width, and if not, enables down-scale mode. For a
frame where input is 1080x1920 and output is 1088x1920, this is incorrect
as no down-scale happens, the frame is only padded. Enabling the down-scale
mode in this case results in corrupted frames.
Fix this by adjusting the check to test whether encoded data width is
greater than decoded frame width, and only in that case enable the
down-scale mode.
To generate input test data to trigger this bug, use e.g.:
$ gst-launch-1.0 videotestsrc ! video/x-raw,width=272,height=256,format=I420 ! \
vp9enc ! matroskamux ! filesink location=/tmp/test.vp9
To trigger the bug upon decoding (note that the NV12 must be forced, as
that assures the output data would pass the G2 postproc):
$ gst-launch-1.0 filesrc location=/tmp/test.vp9 ! matroskademux ! vp9parse ! \
v4l2slvp9dec ! video/x-raw,format=NV12 ! videoconvert ! fbdevsink

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jacopo Mondi <jacopo.mondi@ideasonboard.com>
[ Upstream commit eeaa47d182fedfe68b8fd40ef3798761c8904791 ]
The ov5640_update_pixel_rate() function handles the parallel and MIPI
CSI-2 cases separately.
When running on a parallel setup the V4L2_CID_PIXEL_RATE value is
calculated at the beginning of the function using the values configured
with the frame_interval operations, and then the function immediately
returns.
The remaining of the function handles the MIPI CSI-2 configuration and
should not use the 'current_fr' and 'def_fps' fields as those are only
relevant for parallel mode.
Drop a small section of dead code that updates vblank using
frame_interval on a MIPI CSI-2 setup.

[ Upstream commit 8fc29e3c9f682d4ad9b0764d44ecc6c19b000051 ]
The value of V4L2_CID_VBLANK control is initialized to default vblank
value of 640x480 when driver probe. When OV5640 work at DVP mode, the
control value won't update and lead to sensor can't output data if the
resolution remain the same as last time since incorrect total vertical
size. So update it when there is a new value applied.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zheng Wang <zyytlz.wz@163.com>
[ Upstream commit bd5b50b329e850d467e7bcc07b2b6bde3752fbda ]
There may be some a race condition between timer function
bttv_irq_timeout and bttv_remove. The timer is setup in
probe and there is no timer_delete operation in remove
function. When it hit kfree btv, the function might still be
invoked, which will cause use after free bug.
This bug is found by static analysis, it may be false positive.
Fix it by adding del_timer_sync invoking to the remove function.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fei Shao <fshao@chromium.org>
[ Upstream commit 0aeccc63f3bc4cfd49dc4893da1409402ee6b295 ]
The driver uses the upper-bound approach to decide the target JPEG
encode quality, but there's a logic bug that if the desired quality is
higher than what the driver can support, the driver falls back to using
the worst quality.
Fix the bug by assuming using the best quality in the beginning, and
with trivial refactor to avoid long lines.

[ Upstream commit 36fe515c1a3cd5eac148e8a591a82108d92d5522 ]
According to H6 user manual, resets should always be de-asserted before
clocks are enabled. This is also consistent with vendor driver.

From: Pratyush Yadav <p.yadav@ti.com>
[ Upstream commit b2701715301a49b53d05c7d43f3fedc3b8743bfc ]
The notifier is added to the global notifier list when registered. When
the module is removed, the struct csi2rx_priv in which the notifier is
embedded, is destroyed. As a result the notifier list has a reference to
a notifier that no longer exists. This causes invalid memory accesses
when the list is iterated over. Similar for when the probe fails.
Unregister and clean up the notifier to avoid this.

Currently, noinc writes are cached as if they were standard incrementing

want to cache the last value written to the register, as is done in the
accelerated noinc handler (regmap_noinc_readwrite).

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
[ Upstream commit 2d6812b41e0d832919d72c72ebddf361df53ba1b ]
Instead of using one allocation per capture channel, use a single one. Also
store it in driver data instead of chip data.
This has several advantages:
- driver data isn't cleared when pwm_put() is called
- Reduces memory fragmentation
Also register the pwm chip only after the per capture channel data is
initialized as the capture callback relies on this initialization and it
might be called even before pwmchip_add() returns.
It would be still better to have struct sti_pwm_compat_data and the
per-channel data struct sti_cpt_ddata in a single memory chunk, but that's
not easily possible because the number of capture channels isn't known yet
when the driver data struct is allocated.

From: Florian Fainelli <florian.fainelli@broadcom.com>
[ Upstream commit e9bc4411548aaa738905d37851a0146c16b3bb21 ]
The suspend/resume functions currently utilize
clk_disable()/clk_enable() respectively which may be no-ops with certain
clock providers such as SCMI. Fix this to use clk_disable_unprepare()
and clk_prepare_enable() respectively as we should.

The put_device() calls rmi_release_function() which frees "fn" so the
dereference on the next line "fn->num_of_irqs" is a use after free.
Move the put_device() to the end to fix this.

The IXP4xx watchdog in early "A0" silicon is unreliable and

USRobotics USR8200 the watchdog is the only restart option,
so implement a "dummy" watchdog that can only support restart
in this case.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Willem de Bruijn <willemb@google.com>
[ Upstream commit 7b3ba18703a63f6fd487183b9262b08e5632da1b ]
LLC reads the mac header with eth_hdr without verifying that the skb
has an Ethernet header.
Syzbot was able to enter llc_rcv on a tun device. Tun can insert
packets without mac len and with user configurable skb->protocol
(passing a tun_pi header when not configuring IFF_NO_PI).

Add a mac_len test before all three eth_hdr(skb) calls under net/llc.
There are further uses in include/net/llc_pdu.h. All these are
protected by a test skb->protocol == ETH_P_802_2. Which does not
protect against this tun scenario.
But the mac_len test added in this patch in llc_fixup_skb will
indirectly protect those too. That is called from llc_rcv before any
other LLC code.
It is tempting to just add a blanket mac_len check in llc_rcv, but
not sure whether that could break valid LLC paths that do not assume
an Ethernet header. 802.2 LLC may be used on top of non-802.3
protocols in principle. The below referenced commit shows that used
to, on top of Token Ring.
At least one of the three eth_hdr uses goes back to before the start
of git history. But the one that syzbot exercises is introduced in
this commit. That commit is old enough (2008), that effectively all
stable kernels should receive this.

From: Dan Carpenter <dan.carpenter@linaro.org>
[ Upstream commit 876f8ab52363f649bcc74072157dfd7adfbabc0d ]
The prp_fill_rct() function can fail. In that situation, it frees the
skb and returns NULL. Meanwhile on the success path, it returns the
original skb. So it's straight forward to fix bug by using the returned
value.

TIPC bearer-related names including link names must be null-terminated
strings. If a link name which is not null-terminated is passed through
netlink, strstr() and similar functions can cause buffer overrun. This
causes the above issue.
This patch changes the nla_policy for bearer-related names from NLA_STRING
to NLA_NUL_STRING. This resolves the issue by ensuring that only
null-terminated strings are accepted as bearer-related names.
syzbot reported similar uninit-value issue related to bearer names [2]. The
root cause of this issue is that a non-null-terminated bearer name was
passed. This patch also resolved this issue.
Fixes: 7be57fc69184 ("tipc: add link get/dump to new netlink api")
Fixes: 0655f6a8635b ("tipc: add bearer disable/enable to new netlink api")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hou Tao <houtao1@huawei.com>
[ Upstream commit fd381ce60a2d79cc967506208085336d3d268ae0 ]
When there are concurrent uref release and bpf timer init operations,
the following sequence diagram is possible. It will break the guarantee
provided by bpf_timer: bpf_timer will still be alive after userspace
application releases or unpins the map. It also will lead to kmemleak
for old kernel version which doesn't release bpf_timer when map is
released.
bpf program X:
bpf_timer_init()
lock timer->lock
read timer->timer as NULL
read map->usercnt != 0
process Y:
close(map_fd)
// put last uref
bpf_map_put_uref()
atomic_dec_and_test(map->usercnt)
array_map_free_timers()
bpf_timer_cancel_and_free()
// just return
read timer->timer is NULL
t = bpf_map_kmalloc_node()
timer->timer = t
unlock timer->lock
Fix the problem by checking map->usercnt after timer->timer is assigned,
so when there are concurrent uref release and bpf timer init, either
bpf_timer_cancel_and_free() from uref release reads a no-NULL timer
or the newly-added atomic64_read() returns a zero usercnt.
Because atomic_dec_and_test(map->usercnt) and READ_ONCE(timer->timer)
in bpf_timer_cancel_and_free() are not protected by a lock, so add
a memory barrier to guarantee the order between map->usercnt and
timer->timer. Also use WRITE_ONCE(timer->timer, x) to match the lockless
read of timer->timer in bpf_timer_cancel_and_free().

I am looking at syzbot reports triggering kernel stack overflows
involving a cascade of ipvlan devices.
We can save 8 bytes in struct flowi_common.
This patch alone will not fix the issue, but is a start.

------------------
From: Jian Shen <shenjian15@huawei.com>
[ Upstream commit 8ffbd1669ed1d58939d6e878dffaa2f60bf961a4 ]
When ptr_ring_init() returns failure in page_pool_init(), free_percpu()
is not called to free pool->recycle_stats, which may cause memory
leak.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit fa2df45af13091f76b89adb84a28f13818d5d631 ]
Initially, commit 4237c75c0a35 ("[MLSXFRM]: Auto-labeling of child
sockets") introduced security_inet_conn_request() in some functions
where reqsk is allocated. The hook is added just after the allocation,
so reqsk's IPv4 remote address was not initialised then.
However, SELinux/Smack started to read it in netlbl_req_setattr()
after the cited commits.
This bug was partially fixed by commit 284904aa7946 ("lsm: Relocate
the IPv4 security_inet_conn_request() hooks").
This patch fixes the last bug in DCCPv4.
Fixes: 389fb800ac8b ("netlabel: Label incoming TCP connections correctly in SELinux")
Fixes: 07feee8f812f ("netlabel: Cleanup the Smack/NetLabel code to fix incoming TCP connections")

relabelled by the lsm.").
Commit 284904aa7946 ("lsm: Relocate the IPv4 security_inet_conn_request()
hooks") fixed that kind of issue only in TCPv4 because IPv6 labeling was
not supported at that time. Finally, the same issue was introduced again
in IPv6.
Let's apply the same fix on DCCPv6 and TCPv6.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: NeilBrown <neilb@suse.de>
[ Upstream commit e8ae8ad479e2d037daa33756e5e72850a7bd37a9 ]
The comment for idr_for_each_entry_ul() states
after normal termination @entry is left with the value NULL
This is not correct in the case where UINT_MAX has an entry in the idr.
In that case @entry will be non-NULL after termination.
No current code depends on the documentation being correct, but to
save future code we should fix it.
Also fix idr_for_each_entry_continue_ul(). While this is not documented
as leaving @entry as NULL, the mellanox driver appears to depend on
it doing so. So make that explicit in the documentation as well as in
the code.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hangbin Liu <liuhangbin@gmail.com>
[ Upstream commit 63e201916b27260218e528a2f8758be47f99bbf4 ]
In the PMTU test, when all previous tests are skipped and the new test
passes, the exit code is set to 0. However, the current check mistakenly
treats this as an assignment, causing the check to pass every time.
Consequently, regardless of how many tests have failed, if the latest test
passes, the PMTU test will report a pass.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hariprasad Kelam <hkelam@marvell.com>
[ Upstream commit 508c58f76ca510956625c945f9b8eb104f2c8208 ]
current implementation is such that tot_tx_queues contains both
xdp queues and normal tx queues. which will be allocated in interface
open calls and deallocated on interface down calls respectively.
With addition of QOS, where send quees are allocated/deallacated upon
user request Qos send queues won't be part of tot_tx_queues. So this
patch renames tot_tx_queues to non_qos_queues.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Subbaraya Sundeep <sbhatta@marvell.com>
[ Upstream commit ab6dddd2a669a0ecc2ce07485c7a15fadbb5a0aa ]
Current implementation is such that the number of Send queues (SQs)
are decided on the device probe which is equal to the number of online
cpus. These SQs are allocated and deallocated in interface open and c
lose calls respectively.
This patch defines new APIs for initializing and deinitializing Send
queues dynamically and allocates more number of transmit queues for
QOS feature.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geetha sowjanya <gakula@marvell.com>
[ Upstream commit 3423ca23e08bf285a324237abe88e7e7d9becfe6 ]
On interface down, the pending SQEs in the NIX get dropped
or drained out during SMQ flush. But skb's pointed by these
SQEs never get free or updated to the stack as respective CQE
never get added.
This patch fixes the issue by freeing all valid skb's in SQ SG list.
Fixes: b1bc8457e9d0 ("octeontx2-pf: Cleanup all receive buffers in SG descriptor")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: D. Wythe <alibuda@linux.alibaba.com>
[ Upstream commit 5211c9729484c923f8d2e06bd29f9322cc42bb8f ]
Considering scenario:
smc_cdc_rx_handler
__smc_release
sock_set_flag
smc_close_active()
sock_set_flag
__set_bit(DEAD) __set_bit(DONE)
Dues to __set_bit is not atomic, the DEAD or DONE might be lost.
if the DEAD flag lost, the state SMC_CLOSED will be never be reached
in smc_close_passive_work:
if (sock_flag(sk, SOCK_DEAD) &&
smc_close_sent_any_close(conn)) {
sk->sk_state = SMC_CLOSED;
} else {
/* just shutdown, but not yet closed locally */
sk->sk_state = SMC_APPFINCLOSEWAIT;
}
Replace sock_set_flags or __set_bit to set_bit will fix this problem.
Since set_bit is atomic.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: D. Wythe <alibuda@linux.alibaba.com>
[ Upstream commit c5bf605ba4f9d6fbbb120595ab95002f4716edcb ]
This patch re-fix the issues mentioned by commit 22a825c541d7
("net/smc: fix NULL sndbuf_desc in smc_cdc_tx_handler()").
Blocking sending message do solve the issues though, but it also
prevents the peer to receive the final message. Besides, in logic,
whether the sndbuf_desc is NULL or not have no impact on the processing
of cdc message sending.
Hence that, this patch allows the cdc message sending but to check the
sndbuf_desc with care in smc_cdc_tx_handler().

From: George Shuklin <george.shuklin@gmail.com>
[ Upstream commit 9fc3bc7643341dc5be7d269f3d3dbe441d8d7ac3 ]
Dell R650xs servers hangs on reboot if tg3 driver calls
tg3_power_down.
This happens only if network adapters (BCM5720 for R650xs) were
initialized using SNP (e.g. by booting ipxe.efi).
The actual problem is on Dell side, but this fix allows servers
to come back alive after reboot.

disk->private_data as NULL as before. UAF may be triggered in nbd_open()
if someone tries to open nbd device right after nbd_put() since nbd has
been free in nbd_dev_remove().
Fix this by implementing ->free_disk and free private data in it.

If one of the underlying disks of raid or dm is set to read-only, then
each io will generate new log, which will cause message storm. This
environment is indeed problematic, however we can't make sure our
naive custormer won't do this, hence use pr_warn_ratelimited() to
prevent message storm in this case.

This commit changes virtio/vsock to use sk_buff instead of
virtio_vsock_pkt. Beyond better conforming to other net code, using
sk_buff allows vsock to use sk_buff-dependent features in the future
(such as sockmap) and improves throughput.

[ Upstream commit 3a5cc90a4d1756072619fe511d07621bdef7f120 ]
If the same remote peer, using the same port, tries to connect
to a server on a listening port more than once, the server will
reject the connection, causing a "connection reset by peer"
error on the remote peer. This is due to the presence of a
dangling socket from a previous connection in both the connected
and bound socket lists.
The inconsistency of the above lists only occurs when the remote
peer disconnects and the server remains active.
This bug does not occur when the server socket is closed:
virtio_transport_release() will eventually schedule a call to
virtio_transport_do_close() and the latter will remove the socket
from the bound and connected socket lists and clear the sk_buff.
However, virtio_transport_do_close() will only perform the above
actions if it has been scheduled, and this will not happen
if the server is processing the shutdown message from a remote peer.
To fix this, introduce a call to vsock_remove_sock()
when the server is handling a client disconnect.
This is to remove the socket from the bound and connected socket
lists without clearing the sk_buff.

From: Heiner Kallweit <hkallweit1@gmail.com>
[ Upstream commit 8999ce4cfc87e61b4143ec2e7b93d8e92e11fa7f ]
So far we ignore the setting of IFF_MULTICAST. Fix this and clear bit
AcceptMulticast if IFF_MULTICAST isn't set.
Note: Based on the implementations I've seen it doesn't seem to be 100% clear
what a driver is supposed to do if IFF_ALLMULTI is set but IFF_MULTICAST
is not. This patch is based on the understanding that IFF_MULTICAST has
precedence.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeremy Sowden <jeremy@azazel.net>
[ Upstream commit 6f56ad1b92328997e1b1792047099df6f8d7acb5 ]
`nf_nat_redirect_ipv4` takes a `struct nf_nat_ipv4_multi_range_compat`,
but converts it internally to a `struct nf_nat_range2`. Change the
function to take the latter, factor out the code now shared with
`nf_nat_redirect_ipv6`, move the conversion to the xt_REDIRECT module,
and update the ipv4 range initialization in the nft_redir module.
Replace a bare hex constant for 127.0.0.1 with a macro.
Remove `WARN_ON`. `nf_nat_setup_info` calls `nf_ct_is_confirmed`:
/* Can't setup nat info for confirmed ct. */
if (nf_ct_is_confirmed(ct))
return NF_ACCEPT;
This means that `ct` cannot be null or the kernel will crash, and
implies that `ctinfo` is `IP_CT_NEW` or `IP_CT_RELATED`.
nft_redir has separate ipv4 and ipv6 call-backs which share much of
their code, and an inet one switch containing a switch that calls one of
the others based on the family of the packet. Merge the ipv4 and ipv6
ones into the inet one in order to get rid of the duplicate code.
Const-qualify the `priv` pointer since we don't need to write through
it.
Assign `priv->flags` to the range instead of OR-ing it in.
Set the `NF_NAT_RANGE_PROTO_SPECIFIED` flag once during init, rather
than on every eval.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Westphal <fw@strlen.de>
[ Upstream commit 80abbe8a8263106fe45a4f293b92b5c74cc9cc8a ]
The ipv6 redirect target was derived from the ipv4 one, i.e. its
identical to a 'dnat' with the first (primary) address assigned to the
network interface. The code has been moved around to make it usable
from nf_tables too, but its still the same as it was back when this
was added in 2012.
IPv6, however, has different types of addresses, if the 'wrong' address
comes first the redirection does not work.
In Daniels case, the addresses are:
inet6 ::ffff:192 ...
inet6 2a01: ...
... so the function attempts to redirect to the mapped address.
Add more checks before the address is deemed correct:
1. If the packets' daddr is scoped, search for a scoped address too
2. skip tentative addresses
3. skip mapped addresses
Use the first address that appears to match our needs.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anup Patel <apatel@ventanamicro.com>
[ Upstream commit c4676f8dc1e12e68d6511f9ed89707fdad4c962c ]
The riscv_of_processor_hartid() used by riscv_of_parent_hartid() fails
for HARTs disabled in the DT. This results in the following warning
thrown by the RISC-V INTC driver for the E-core on SiFive boards:
[ 0.000000] riscv-intc: unable to find hart id for /cpus/cpu@0/interrupt-controller
The riscv_of_parent_hartid() is only expected to read the hartid
from the DT so we directly call of_get_cpu_hwid() instead of calling
riscv_of_processor_hartid().

From: Erik Kurzinger <ekurzinger@nvidia.com>
[ Upstream commit 101c9f637efa1655f55876644d4439e552267527 ]
If DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT is invoked with the
DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE flag set but no fence has yet been
submitted for the given timeline point the call will fail immediately
with EINVAL. This does not match the intended behavior where the call
should wait until the fence has been submitted (or the timeout expires).
The following small example program illustrates the issue. It should
wait for 5 seconds and then print ETIME, but instead it terminates right
away after printing EINVAL.
#include <stdio.h>
#include <fcntl.h>
#include <time.h>
#include <errno.h>
#include <xf86drm.h>
int main(void)
{
int fd = open("/dev/dri/card0", O_RDWR);
uint32_t syncobj;
drmSyncobjCreate(fd, 0, &syncobj);
struct timespec ts;
clock_gettime(CLOCK_MONOTONIC, &ts);
uint64_t point = 1;
if (drmSyncobjTimelineWait(fd, &syncobj, &point, 1,
ts.tv_sec * 1000000000 + ts.tv_nsec + 5000000000, // 5s
DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE, NULL)) {

[ Upstream commit 004fc58edea6f00db9ad07b40b882e8d976f7a54 ]
Property 'playback-codecs' is referenced as 'speaker-codec' in the error
message, and this can lead to confusion.
Correct the error message such that the correct property name is
referenced.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jerome Brunet <jbrunet@baylibre.com>
[ Upstream commit 15be353d55f9e12e34f9a819f51eb41fdef5eda8 ]
The HDMI hotplug callback to the hdmi-codec is currently registered when
jack is set.
The hotplug not only serves to report the ASoC jack state but also to get
the ELD. It should be registered when the component probes instead, so it
does not depend on the card driver registering a jack for the HDMI to
properly report the ELD.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jens Axboe <axboe@kernel.dk>
commit f8f9ab2d98116e79d220f1d089df7464ad4e026d upstream.
io_uring does non-blocking connection attempts, which can yield some
unexpected results if a connect request is re-attempted by an an
application. This is equivalent to the following sync syscall sequence:
sock = socket(AF_INET, SOCK_STREAM | SOCK_NONBLOCK, IPPROTO_TCP);
connect(sock, &addr, sizeof(addr);
ret == -1 and errno == EINPROGRESS expected here. Now poll for POLLOUT
on sock, and when that returns, we expect the socket to be connected.
But if we follow that procedure with:
connect(sock, &addr, sizeof(addr));
you'd expect ret == -1 and errno == EISCONN here, but you actually get
ret == 0. If we attempt the connection one more time, then we get EISCON
as expected.
io_uring used to do this, but turns out that bluetooth fails with EBADFD
if you attempt to re-connect. Also looks like EISCONN _could_ occur with
this sequence.
Retain the ->in_progress logic, but work-around a potential EISCONN or
EBADFD error and only in those cases look at the sock_error(). This
should work in general and avoid the odd sequence of a repeated connect
request returning success when the socket is already connected.
This is all a side effect of the socket state being in a CONNECTING
state when we get EINPROGRESS, and only a re-connect or other related
operation will turn that into CONNECTED.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dominique Martinet <dominique.martinet@atmark-techno.com>
commit 421b605edb1ce611dee06cf6fd9a1c1f2fd85ad0 upstream.
This reverts commit 84ee19bffc9306128cd0f1c650e89767079efeff.
The commit above made quirks with an OEMID fail to be applied, as they
were checking card->cid.oemid for the full 16 bits defined in MMC_FIXUP
macros but the field would only contain the bottom 8 bits.
eMMC v5.1A might have bogus values in OEMID's higher bits so another fix
will be made, but it has been decided to revert this until that is ready.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit dec96fc2dcb59723e041416b8dc53e011b4bfc2e ]
In the tree search v2 ioctl we use the type size_t, which is an unsigned
long, to track the buffer size in the local variable 'buf_size'. An
unsigned long is 32 bits wide on a 32 bits architecture. The buffer size
defined in struct btrfs_ioctl_search_args_v2 is a u64, so when we later
try to copy the local variable 'buf_size' to the argument struct, when
the search returns -EOVERFLOW, we copy only 32 bits which will be a
problem on big endian systems.
Fix this by using a u64 type for the buffer sizes, not only at
btrfs_ioctl_tree_search_v2(), but also everywhere down the call chain
so that we can use the u64 at btrfs_ioctl_tree_search_v2().
Fixes: cc68a8a5a433 ("btrfs: new ioctl TREE_SEARCH_V2")

A cleanup, but I don't believe we need it in -stable.
