975e2590a7 Bluetooth: hci_conn: do return error from hci_enhanced_setup_sync()
[ Upstream commit 0eaf7c7e85 ]

The commit e07a06b4eb ("Bluetooth: Convert SCO configure_datapath to
hci_sync") missed to update the *return* statement under the *case* of
BT_CODEC_TRANSPARENT in hci_enhanced_setup_sync(), which led to returning
success (0) instead of the negative error code (-EINVAL).  However, the
result of hci_enhanced_setup_sync() seems to be ignored anyway, since NULL
gets passed to hci_cmd_sync_queue() as the last argument in that case and
the only function interested in that result is specified by that argument.

dcb367e707 Bluetooth: hci_event: fix MTU for BN == 0 in CIS Established
[ Upstream commit 0b3725dbf6 ]

BN == 0x00 in CIS Established means no isochronous data for the
corresponding direction (Core v6.1 pp. 2394). In this case SDU MTU
should be 0.

However, the specification does not say the Max_PDU_C_To_P or P_To_C are
then zero.  Intel AX210 in Framed CIS mode sets nonzero Max_PDU for
direction with zero BN.  This causes failure later when we try to LE
Setup ISO Data Path for disabled direction, which is disallowed (Core
v6.1 pp. 2750).

Fix by setting SDU MTU to 0 if BN == 0.

bdb19cd0de net: bridge: fix soft lockup in br_multicast_query_expired()
[ Upstream commit d1547bf460 ]

When set multicast_query_interval to a large value, the local variable
'time' in br_multicast_send_query() may overflow. If the time is smaller
than jiffies, the timer will expire immediately, and then call mod_timer()
again, which creates a loop and may trigger the following soft lockup
issue.

  watchdog: BUG: soft lockup - CPU#1 stuck for 221s! [rb_consumer:66]

The multicast_startup_query_interval can also cause this issue. Similar to

87c36bef9e net: xilinx: axienet: Fix RX skb ring management in DMAengine mode
[ Upstream commit fd980bf6e9 ]

Submit multiple descriptors in axienet_rx_cb() to fill Rx skb ring. This
ensures the ring "catches up" on previously missed allocations.

Increment Rx skb ring head pointer after BD is successfully allocated.
Previously, head pointer was incremented before verifying if descriptor is
successfully allocated and has valid entries, which could lead to ring
state inconsistency if descriptor setup failed.

These changes improve reliability by maintaining adequate descriptor
availability and ensuring proper ring buffer state management.

f884c7b15e RDMA/bnxt_re: Fix a possible memory leak in the driver

60a56f5a54 rust: alloc: replace aligned_size() with Kmalloc::aligned_layout()
[ Upstream commit fde578c862 ]

aligned_size() dates back to when Rust did support kmalloc() only, but
is now used in ReallocFunc::call() and hence for all allocators.

However, the additional padding applied by aligned_size() is only
required by the kmalloc() allocator backend.

Hence, replace aligned_size() with Kmalloc::aligned_layout() and use it
for the affected allocators, i.e. kmalloc() and kvmalloc(), only.

While at it, make Kmalloc::aligned_layout() public, such that Rust
abstractions, which have to call subsystem specific kmalloc() based
allocation primitives directly, can make use of it.

846bda1478 iosys-map: Fix undefined behavior in iosys_map_clear()
[ Upstream commit 5634c8cb29 ]

The current iosys_map_clear() implementation reads the potentially
uninitialized 'is_iomem' boolean field to decide which union member
to clear. This causes undefined behavior when called on uninitialized
structures, as 'is_iomem' may contain garbage values like 0xFF.

UBSAN detects this as:
    UBSAN: invalid-load in include/linux/iosys-map.h:267
    load of value 255 is not a valid value for type '_Bool'

Fix by unconditionally clearing the entire structure with memset(),
eliminating the need to read uninitialized data and ensuring all
fields are set to known good values.

f7798cb62d drm/format-helper: Add generic conversion to 32-bit formats
[ Upstream commit d55d0b066f ]

Add drm_fb_xfrm_line_32to32() to implement conversion from 32-bit
pixels to 32-bit pixels. The pixel-conversion is specified by the
given callback parameter. Mark the helper as always_inline to avoid
overhead from function calls.

Then implement all existing line-conversion functions with the new
generic call and the respective pixel-conversion helper.

7a60c21384 cgroup/cpuset: Fix a partition error with CPU hotplug
[ Upstream commit 150e298ae0 ]

It was found during testing that an invalid leaf partition with an
empty effective exclusive CPU list can become a valid empty partition
with no CPU afer an offline/online operation of an unrelated CPU. An
empty partition root is allowed in the special case that it has no
task in its cgroup and has distributed out all its CPUs to its child
partitions. That is certainly not the case here.

The problem is in the cpumask_subsets() test in the hotplug case
(update with no new mask) of update_parent_effective_cpumask() as it
also returns true if the effective exclusive CPU list is empty. Fix that
by addding the cpumask_empty() test to root out this exception case.
Also add the cpumask_empty() test in cpuset_hotplug_update_tasks()
to avoid calling update_parent_effective_cpumask() for this special case.

Since commit d74b27d63a ("cgroup/cpuset: Change cpuset_rwsem

used the cpuslocked version of the static branch API to enable

same for cpusets_insane_config_key.

The cpusets_insane_config_key can be enabled in the
check_insane_mems_config() which is called from update_nodemask()
or cpuset_hotplug_update_tasks() with both cpu hotplug lock and
cpuset_mutex held. Deadlock can happen with a pending hotplug event that
tries to acquire the cpu hotplug write lock which will block further
cpus_read_lock() attempt from check_insane_mems_config(). Fix that by
switching to use static_branch_enable_cpuslocked().

commit d8df126349 upstream.

Since

  923f3a2b48 ("x86/resctrl: Query LLC monitoring properties once during boot")

resctrl_cpu_detect() has been moved from common CPU initialization code to
the vendor-specific BSP init helper, while Hygon didn't put that call in their
code.

This triggers a division by zero fault during early booting stage on our
machines with X86_FEATURE_CQM* supported, where get_rdt_mon_resources() tries
to calculate mon_l3_config with uninitialized boot_cpu_data.x86_cache_occ_scale.

Add the missing resctrl_cpu_detect() in the Hygon BSP init helper.

3439c15ae9 tls: fix handling of zero-length records on the rx_list
commit 62708b9452 upstream.

Each recvmsg() call must process either
 - only contiguous DATA records (any number of them)
 - one non-DATA record

If the next record has different type than what has already been
processed we break out of the main processing loop. If the record
has already been decrypted (which may be the case for TLS 1.3 where
we don't know type until decryption) we queue the pending record
to the rx_list. Next recvmsg() will pick it up from there.

Queuing the skb to rx_list after zero-copy decrypt is not possible,
since in that case we decrypted directly to the user space buffer,
and we don't have an skb to queue (darg.skb points to the ciphertext
skb for access to metadata like length).

Only data records are allowed zero-copy, and we break the processing
loop after each non-data record. So we should never zero-copy and
then find out that the record type has changed. The corner case
we missed is when the initial record comes from rx_list, and it's
zero length.

9c4afcaf82 ovl: use I_MUTEX_PARENT when locking parent in ovl_create_temp()
commit 5f1c8965e7 upstream.

ovl_create_temp() treats "workdir" as a parent in which it creates an
object so it should use I_MUTEX_PARENT.

Prior to the commit identified below the lock was taken by the caller
which sometimes used I_MUTEX_PARENT and sometimes used I_MUTEX_NORMAL.
The use of I_MUTEX_NORMAL was incorrect but unfortunately copied into
ovl_create_temp().

Note to backporters: This patch only applies after the last Fixes given
below (post v6.16).  To fix the bug in v6.7 and later the
inode_lock() call in ovl_copy_up_workdir() needs to nest using
I_MUTEX_PARENT.

f483319e1f drm/i915/icl+/tc: Cache the max lane count value
[ Upstream commit 5fd3523654 ]

The PHY's pin assignment value in the TCSS_DDI_STATUS register - as set
by the HW/FW based on the connected DP-alt sink's TypeC/PD pin
assignment negotiation - gets cleared by the HW/FW on LNL+ as soon as
the sink gets disconnected, even if the PHY ownership got acquired
already by the driver (and hence the PHY itself is still connected and
used by the display). This is similar to how the PHY Ready flag gets
cleared on LNL+ in the same register.

To be able to query the max lane count value on LNL+ - which is based on
the above pin assignment - at all times even after the sink gets
disconnected, the max lane count must be determined and cached during
the PHY's HW readout and connect sequences. Do that here, leaving the
actual use of the cached value to a follow-up change.

v2: Don't read out the pin configuration if the PHY is disconnected.

51ffbf14e2 compiler: remove __ADDRESSABLE_ASM{_STR,}() again

__ADDRESSABLE_ASM_STR() is where the necessary stringification happens.
As long as "sym" doesn't contain any odd characters, no quoting is
required for its use with .quad / .long. In fact the quotation gets in
the way with gas 2.25; it's only from 2.26 onwards that quoted symbols
are half-way properly supported.

However, assembly being different from C anyway, drop
__ADDRESSABLE_ASM_STR() and its helper macro altogether. A simple
.global directive will suffice to get the symbol "declared", i.e. into
the symbol table. While there also stop open-coding STATIC_CALL_TRAMP()
and STATIC_CALL_KEY().

d0c68045b8 tracing: Limit access to parser->buffer when trace_get_user failed
[ Upstream commit 6a909ea83f ]

When the length of the string written to set_ftrace_filter exceeds
FTRACE_BUFF_MAX, the following KASAN alarm will be triggered:

BUG: KASAN: slab-out-of-bounds in strsep+0x18c/0x1b0
Read of size 1 at addr ffff0000d00bd5ba by task ash/165

CPU: 1 UID: 0 PID: 165 Comm: ash Not tainted 6.16.0-g6bcdbd62bd56-dirty

 el0_svc+0xec/0xf0

 el0t_64_sync+0x1ac/0x1b0

The reason is that trace_get_user will fail when processing a string
longer than FTRACE_BUFF_MAX, but not set the end of parser->buffer to 0.
Then an OOB access will be triggered in ftrace_regex_release->
ftrace_process_regex->strsep->strpbrk. We can solve this problem by
limiting access to parser->buffer when trace_get_user failed.

e1fdc506c3 tracing: Remove unneeded goto out logic
[ Upstream commit c89504a703 ]

Several places in the trace.c file there's a goto out where the out is
simply a return. There's no reason to jump to the out label if it's not
doing any more logic but simply returning from the function.

Replace the goto outs with a return and remove the out labels.

c456108605 iio: temperature: maxim_thermocouple: use DMA-safe buffer for spi_read()
[ Upstream commit ae5bc07ec9 ]

Replace using stack-allocated buffers with a DMA-safe buffer for use
with spi_read(). This allows the driver to be safely used with
DMA-enabled SPI controllers.

The buffer array is also converted to a struct with a union to make the
usage of the memory in the buffer more clear and ensure proper alignment.

f49697dfba usb: dwc3: Remove WARN_ON for device endpoint command timeouts
commit 45eae113dc upstream.

This commit addresses a rarely observed endpoint command timeout
which causes kernel panic due to warn when 'panic_on_warn' is enabled
and unnecessary call trace prints when 'panic_on_warn' is disabled.
It is seen during fast software-controlled connect/disconnect testcases.
The following is one such endpoint command timeout that we observed:

1. Connect
   =======
->dwc3_thread_interrupt
 ->dwc3_ep0_interrupt
  ->configfs_composite_setup
   ->composite_setup
    ->usb_ep_queue
     ->dwc3_gadget_ep0_queue
      ->__dwc3_gadget_ep0_queue
       ->__dwc3_ep0_do_control_data
        ->dwc3_send_gadget_ep_cmd

2. Disconnect
   ==========
->dwc3_thread_interrupt
 ->dwc3_gadget_disconnect_interrupt
  ->dwc3_ep0_reset_state
   ->dwc3_ep0_end_control_data
    ->dwc3_send_gadget_ep_cmd

In the issue scenario, in Exynos platforms, we observed that control
transfers for the previous connect have not yet been completed and end
transfer command sent as a part of the disconnect sequence and
processing of USB_ENDPOINT_HALT feature request from the host timeout.
This maybe an expected scenario since the controller is processing EP
commands sent as a part of the previous connect. It maybe better to
remove WARN_ON in all places where device endpoint commands are sent to
avoid unnecessary kernel panic due to warn.

900fdc733f usb: dwc3: Ignore late xferNotReady event to prevent halt timeout
commit 58577118cc upstream.

During a device-initiated disconnect, the End Transfer command resets
the event filter, allowing a new xferNotReady event to be generated
before the controller is fully halted. Processing this late event
incorrectly triggers a Start Transfer, which prevents the controller
from halting and results in a DSTS.DEVCTLHLT bit polling timeout.

Ignore the late xferNotReady event if the controller is already in a
disconnected state.

2f7fc6ec5a usb: xhci: Fix slot_id resource race conflict
commit 2eb0337615 upstream.

xHC controller may immediately reuse a slot_id after it's disabled,
giving it to a new enumerating device before the xhci driver freed
all resources related to the disabled device.

In such a scenario, device-A with slot_id equal to 1 is disconnecting
while device-B is enumerating, device-B will fail to enumerate in the
follow sequence.

1.[device-A] send disable slot command
2.[device-B] send enable slot command
3.[device-A] disable slot command completed and wakeup waiting thread
4.[device-B] enable slot command completed with slot_id equal to 1 and
	     wakeup waiting thread
5.[device-B] driver checks that slot_id is still in use (by device-A) in
	     xhci_alloc_virt_device, and fail to enumerate due to this
	     conflict
6.[device-A] xhci->devs[slot_id] set to NULL in xhci_free_virt_device

To fix driver's slot_id resources conflict, clear xhci->devs[slot_id] and
xhci->dcbba->dev_context_ptrs[slot_id] pointers in the interrupt context
when disable slot command completes successfully. Simultaneously, adjust
function xhci_free_virt_device to accurately handle device release.
